Selling online means navigating sales tax rules that differ in nearly every state. Below are clear answers to the Frequently Asked Questions (FAQs) ecommerce and CPG brands ask most, from nexus to registration to back taxes.
Do I Need To Collect Sales Tax?
Yes. Most tangible products sold online are taxable, but the rules vary by state; you only need to collect sales tax in states where you have nexus.Taxability gets more complicated beyond physical goods. Services, SaaS, apparel, and digital goods may be taxed differently depending on the jurisdiction. Selling through marketplaces adds another layer, because it affects who is responsible for collecting and remitting the tax.TaxHero’s full-service solution automatically handles taxability determinations, so you never have to guess.
What Is Nexus and Why Does It Matter?
Nexus is the connection between a seller and a state that triggers a sales tax obligation. If you have nexus in a state, you are legally required to register, collect, and remit sales tax in that state.Understanding nexus is the first step toward staying compliant and avoiding costly penalties. There are two main types.
What Creates Physical Nexus?
Having a tangible presence in a state creates physical nexus.Common triggers include:
Offices
Warehouses
Employees
Certain activities at trade shows
Third-party fulfillment locations
Using third-party fulfillment centers can also create nexus when your inventory is stored in another state. The rules vary by state, so review your specific business activities rather than assuming every activity creates the same obligations.
What Creates Economic Nexus
Economic nexus is based on your sales volume or transaction count in a state. The Supreme Court’s 2018 South Dakota v. Wayfairruling established that states can require out-of-state sellers to collect sales tax once they exceed a sales threshold.Economic nexus thresholds vary by state. Many states use a $100,000 sales threshold, while others set different thresholds or impose additional transaction requirements. Several states have also eliminated their transaction-count thresholds. Check each state’s current rules, including which sales count toward the threshold and the measurement period. Ongoing monitoring helps growing ecommerce brands identify potential registration obligations.
How Do I Know Where I Have Nexus?
Map your sales data against each state’s economic nexus thresholds, and review your physical footprint (inventory, staff, locations) alongside it.Manual tracking is error-prone and time-consuming, especially if you sell in many states. TaxHero’s nexus monitoring service continuously tracks your exposure and alerts you before you cross a threshold, so you can act in time. Because real sales tax accountants review your situation, you get expert judgment and not just a spreadsheet flag.
Does Selling on a Marketplace Affect My Nexus?
Yes, but not in the way many sellers assume.Marketplace facilitator laws generally require qualifying platforms like Amazon and Walmart Marketplace to collect and remit sales tax on taxable marketplace sales where the laws apply.However, sellers may still have registration, reporting, and recordkeeping obligations. Sales through their own websites and other channels can create separate collection responsibilities.
Does storing inventory in an Amazon fulfillment center create sales tax nexus?
Yes. Inventory stored in a state through Amazon’s Fulfillment by Amazon (FBA) program can create physical nexus, even when Amazon collects sales tax on marketplace transactions. Sellers may still need to register, file returns, or meet other state reporting requirements.
How Do I Register To Collect Sales Tax?
Register with each state’s department of revenue where you have nexus before you begin collecting. The process looks like this:
Identify the states where you have nexus.
Gather your business information (entity details, EIN, ownership information, and so on).
Register with each state’s department of revenue.
Some states don’t require registration at all. The NOMAD states (New Hampshire, Oregon, Montana, Alaska, and Delaware) have no statewide sales tax, though some jurisdictions in Alaska impose local sales taxes and local permits may be required.Need help getting your sales tax permit? Check our step-by-step guide. If you prefer a hands-off registration process, TaxHero also handles the paperwork for ecommerce brands, removing the administrative burden entirely.
How Often Do I Need To File Sales Tax Returns?
Sales tax filing frequency varies by state. Depending on the jurisdiction, businesses may need to file monthly, quarterly, or annually. States may assign filing schedules based on tax liability, sales volume, or other applicable criteria. Requirements and deadlines differ across the 45 states with a general statewide sales tax, Washington, D.C., and hundreds of independent, home-rule local jurisdictions.Alaska doesn’t impose a statewide sales tax, but its local municipalities do. Filing returns through the local government or the ARSSTC (Alaska Remote Sellers Sales Tax Commission) is another factor businesses selling into that state shouldn’t overlook.
What If I Have Unpaid Sales Tax From Past Years?
If you have unpaid sales tax, the total amount owed typically varies based on the specific state laws, the outstanding tax balance, and how long the liability remained unaddressed. This commonly happens to many ecommerce brands that discover unexpected nexus obligations as they scale.Voluntary disclosure agreements (VDAs) may help an eligible business resolve past sales tax exposure. Depending on the state and the agreement, benefits may include reduced or waived penalties and a limited lookback period. Eligibility rules vary, and businesses that have already been contacted by a tax authority may not qualify.TaxHero has also helped businesses address historical sales tax exposure. Read how one brand resolved a sales tax audit involving nearly $53,900 in liability.

Ready to simplify sales tax compliance?Book a consultation now to discuss your business, understand your potential compliance gaps, and explore how a managed solution can support your growth. Do small businesses need to collect sales tax? It depends. If your business sells taxable goods or services and has sales tax nexus in a state, you generally must register, collect sales tax when required, and file returns there.Nexus can come from a physical presence or from crossing a state’s economic threshold, and the rules differ in every sales-tax state. The sections below break down how it all works so that each one can stand on its own.
Why Sales Tax Compliance Is More Complex Than Ever
Sales tax obligations have grown significantly in recent years. States have expanded sales-tax rules in some areas, including certain services and digital products, while others continue to exempt many of these transactions. At the same time, enforcement is intensifying. State tax authorities also have more tools to identify businesses with potential sales tax obligations, increasing the importance of accurate registration, collection, and filing.For ecommerce and CPG brands selling into many states, this complexity compounds quickly. Every state can bring its own rates, rules, registration process, and filing calendar.
What’s Changing In Sales Tax Right Now?
Sales tax rules vary by state and can change over time. Small businesses selling across state lines should monitor several areas:
Taxability of products and services. States treat certain services, software, and digital products differently. Review the rules that apply to your specific products.
Updated nexus thresholds. States continue to update their economic nexus rules, such as setting their own sales thresholds and measurement methods. Some also have changed or eliminated transaction-count tests.
Marketplace facilitator definitions. Many states require qualifying marketplaces to collect and remit tax on facilitated sales. Sellers may still have separate registration, reporting, or collection obligations
Online sales remain a focal point for state tax authorities. Staying current with these changes is essential to avoiding penalties, since a missed rule change can quietly create months of uncollected tax.
Understanding Sales Tax Nexus
Nexus is the connection between your business and a state that gives that state the right to require you to collect and remit sales tax. There are two primary types:
Physical nexus comes from a tangible presence, such as an office, store, employees, or property in the state. It can also arise in less obvious ways. Inventory stored in a fulfillment center, employees working in a state, or certain in-state representatives and affiliate arrangements may create nexus, depending on state law and the specific circumstances.
Economic nexuscomes from your sales activity. If you exceed a state’s sales or transaction threshold, you may owe sales tax in that state even without a physical presence.
Thresholds, registration requirements, and filing deadlines all vary by state, so there is no single rule to memorize. You should review these activities alongside their sales figures when evaluating registration requirements.
How Economic Nexus Affects Ecommerce Brands
The2018 South Dakota vs. Wayfairdecision changed the landscape by allowing states to require certain remote sellers to collect sales tax based on economic activity in the state, even without a physical presence. States then adopted their own economic nexus thresholds and requirements.
For ecommerce brands, this means growth can trigger nexus in multiple states faster than many business owners expect. A strong holiday season or a viral product can push you past thresholds in several states at once.
Sales Tax Exemptions and Certificate Management
Not every sale is taxable. Common exemption categories include:
Resale:Purchases by a business that will resell the items
Manufacturing: Materials or equipment used in production
Agriculture: Qualifying farm-related purchases
Nonprofit: Purchases by qualifying exempt organizations
When a customer claims an exemption, sellers generally need to obtain and retain the documentation required by the applicable state. Requirements vary by state and exemption type, so businesses should make sure certificates are complete, valid, and properly maintained.
Managing exemption certificates requires consistent recordkeeping. Missing documentation, incomplete forms, or outdated certificates can create problems during an audit. You need to maintain organized records and review certificates in accordance with applicable state requirements.
Filing, Deadlines, and Reporting Requirements
Once you are registered, each state assigns a filing frequency, such as monthly, quarterly, or annually. The frequency may depend on factors such as your sales volume, tax liability, or filing history, and it can change as your business grows.There’s also a difference in where you file. Most states administer state sales tax and many applicable local taxes through a state-level system.Some jurisdictions have different procedures. Colorado, Louisiana, and Alaska are examples where certain local taxes may involve separate registration, collection, or filing requirements.Late filings lead to penalties and interest and may create additional compliance issues with the tax authority. A reliable system, such as automated reminders and filing workflows, can help reduce missed deadlines as operations expand.
How Online and Digital Sales Create Sales Tax Obligations
Selling across state lines through your own website or an ecommerce platform can trigger sales tax responsibilities in each state where you have nexus. How those obligations work depends on how the sale happens:
Marketplace-facilitated sales: A qualifying marketplace generally collects and remits sales tax when required by state law. However, you still need to register, file returns, report marketplace sales, or meet other state requirements.
Direct sales: when you sell through your own site, you are responsible for collecting, reporting, and remitting the tax.
Digital products and software subscriptions require an additional review. States differ in how they classify and tax downloadable products, electronically delivered software, and SaaS (Software-as-a-Service).
The tax treatment depends on the applicable state’s law and the characteristics of the product or service. You should verify the current rules for each state where they have sales tax obligations.
Common Sales Tax Mistakes Small Businesses Make
Most compliance problems are common and fixable. Here are the errors we see most often:
Failing to identify nexus. Not tracking sales and activity by state means thresholds get crossed unnoticed.
Missing rate changes. State and local rates change often, and outdated rates lead to under- or over-collection.
Assuming marketplaces cover everything. A marketplace may collect and remit tax on marketplace-facilitated sales, but you may still have registration, filing, or collection responsibilities for direct sales and other transactions.
Failing to maintain valid exemption documentation. Missing or outdated certificates can leave you liable for uncollected tax.
Treating filing as an afterthought. Missed deadlines add penalties and interest.
The good news is that each of these can be prevented with the right process. Regularly reviewing nexus, tax rates, exemption documentation, and filing deadlines helps you identify the gaps before they become more difficult to resolve.
How to Build a Stronger Sales Tax Process
You don’t need to fix everything at once. These practical steps reduce risk quickly:
Conduct a nexus review. Look at where you sell, where you store inventory, and where you have people or partners, and compare them against each state’s thresholds.
Centralize your records. Keep sales data, registrations, returns, and certificates in one organized place.
Document your tax decisions. Note why you treat a product or customer as taxable or exempt, so you can support the decision in an audit.
Set up filing reminders. Build a calendar of every state’s due dates, or let a system do it for you.
Automation can help businesses organize sales data, monitor potential nexus obligations, and manage recurring filing tasks. As an ecommerce brand expands into more states, the right processes and tools can make sales tax compliance easier to manage.
Why Automation Is Essential for Growing Ecommerce Brands
Manual sales tax management becomes unsustainable as sales volume and geographic reach expand. Spreadsheets that worked for two states may break down at ten.
Businesses evaluating sales tax solutions should consider their filing volume, registration needs, reporting requirements, level of support, and overall cost when choosing a provider.
Frequently Asked Questions
1. Do small businesses have to collect sales tax in every state where they sell?+
No. You generally must collect sales tax only in states where you have nexus and where your products or services are taxable. Some states have no statewide sales tax at all. Because nexus rules vary, review each state where you sell.
2. What is economic nexus and how do I know if I’ve triggered it?+
Economic nexus is a sales-tax obligation created by the volume of your sales or transactions in a state, regardless of physical presence. To know if you’ve triggered it, compare your sales into each state against that state’s threshold, and monitor this continuously as you grow.
3. What happens if I file a sales tax return late?+
Late filing can result in penalties and interest. If you have missed a deadline, file as soon as possible and consult a tax professional about options such as penalty abatement.
4. How do sales tax rules apply to digital products and online subscriptions?+
It depends on the state. Software, subscriptions, and downloadable goods are taxable in some states and exempt in others, and the rules are frequently updated. Check each state’s current treatment for your specific product.
Read our state-by-state guideline here:Sales Tax on Digital Goods by State
5. What is an exemption certificate and when do I need one?+
An exemption certificate is a document a buyer provides to show that a purchase is not subject to sales tax, for example because it is for resale. You need to collect and keep a valid one whenever you make a sale without charging tax.
Exemption certificates may also be used to claim tax exemptions for other reasons, such as specific organizations that don’t need to pay sales tax or certain qualified business types selling non-taxable goods. Depending on the state, the scope of use for exemption certificates varies.
6. Can selling through Amazon or Shopify create sales tax obligations for my business?+
Yes, it can. Marketplace-facilitated sales may be handled by the marketplace for collection and remittance, but those sales can still affect your registration, filing, or nexus obligations, depending on the state. Whether you use Shopify or your own site, you are generally responsible for collecting and remitting sales tax in any state where you have nexus.
7. How does TaxHero help small businesses manage multistate sales tax compliance?+
TaxHero combines automation with real sales tax professionals to handle nexus monitoring, registrations, exemption certificate management, and filing and payments end-to-end, all with transparent pricing.

As your business grows, you’ll commonly encounter 2 terms: business registration and sales tax registration. They sound similar, but they serve entirely different purposes. Registering your LLC or getting a local business license doesn’t mean you’re allowed to collect sales tax. On the other hand, getting a sales tax permit doesn’t grant you the legal right to operate a physical business entity in that state. Mixing up these two distinct requirements exposes your ecommerce brand to noncompliance risks. This guide clarifies the difference and explains the factors you need to consider before registering.
Business Registration vs. Sales Tax Registration: What’s the Difference?
Business registration and sales tax registration are entirely separate legal processes handled by different state agencies. A common misconception among ecommerce founders is that forming an LLC or incorporating automatically takes care of state tax requirements, but it doesn’t. Each registration serves a distinct operational purpose:
Business Registration: This process establishes your legal business entity (like an LLC or C-Corp) or registers your existing business to do business in a new state when foreign qualification is required. This is typically handled by the Secretary of State and gives your brand the legal right to operate, sign contracts, and open bank accounts in that jurisdiction.
Sales Tax Registration: This registers a business with the relevant state tax authority to collect and remit sales tax when required. The registration process is separate from forming an entity or qualifying to do business in that state.
In short, business registration establishes who you are in a state, while sales tax registration authorizes you to collect sales tax on the state’s behalf. You can’t legally collect a single cent of sales tax from customers until your sales tax registration is approved, regardless of whether your business is officially registered there.
What Is a Sales Tax Permit?
A sales tax permit is a legal license issued by a state government that authorizes your business to collect and remit sales tax. Depending on the state where you trigger nexus, this document may be referred to under different terms, such as:
Seller’s permit
Vendor’s license
Retail license
Regardless of the name, its core purpose remains identical. It acts as your official tax account with a state’s Department of Revenue. Securing this permit is mandatory before you start collecting sales tax from buyers in that state. Collecting tax from customers without an active permit is illegal. States view this practice as pocketing state funds under pretenses, which carries severe financial penalties and risks criminal fraud charges. Once a state approves your permit, they will assign you a specific filing schedule (monthly, quarterly, or annually), often based on your sales volume. You’re then legally required to file a return on that schedule, even if you have zero sales or zero tax to report for that specific period. Need help getting your sales tax permit? Check our step-by-step guide.
When Does an Ecommerce Business Need to Register for Sales Tax?
You only need to register for a sales tax permit once your business establishes a sales tax nexus in a specific state. Sales tax nexus is a legal term for a business connection to a jurisdiction that is significant enough to trigger tax obligations. For ecommerce brands, nexus generally comes down to two types:
Physical Nexus: Triggered by physical assets like warehouses, remote employees, inventory stored in fulfillment centers (like Amazon FBA), or traveling to in-person trade shows. The specific activities that establish nexus depend on state law.
Economic Nexus: Triggered purely by your economic activity. Once your sales revenue or transaction volume in a state crosses a specific dollar amount or number of transactions, you become legally required to register.
Since rules vary by state, you can read our comprehensive guide on economic nexus for a full view of state-by-state rules.The critical takeaway is that nexus is dynamic, not static. As your operations scale and your inventory shifts across fulfillment networks, your tax footprints change. In this case, registering your business in states where you have nexus becomes a separate concern. Establishing a reliable, proactive compliance system is also crucial to keeping your business protected from back taxes, penalties, and audit risks.
Can Someone Handle Sales Tax Registration and Filing for My Business?
Yes, you can fully outsource your sales tax registration, filing, remittance, and ongoing compliance to a third-party partner. A fully managed compliance provider removes the burden of registration and filing by combining software automation with human tax experts who handle the work for you. When working with a full-service partner, your multi-state compliance lifecycle runs on autopilot through a continuous, standard workflow:
Nexus Monitoring: Tracking your sales across all channels to spot where you owe tax next.
Registration: Filing the exact paperwork to secure your state sales tax permits.
Collection: Integrating with your shopping cart to collect the right tax amounts at checkout.
Filing: Preparing and submitting accurate, reconciled tax forms to each state.
Remittance: Automatically transferring the collected tax funds to state treasuries on time.
Ongoing Monitoring: Repeating the loop continuously so you stay compliant as you scale.
What Does a Full-Service Sales Tax Compliance Provider Handle?
For scaling ecommerce brands that are required to register in multiple states or are close to crossing a nexus threshold, outsourcing compliance can help your business save time and resources. A full-service provider generally handles 4 key compliance needs.
1. Sales Tax Registration
Managing registrations across multiple states involves a lot of paperwork, which eats into your business’s productive hours. A full-service provider takes this step off your plate:
Identify Obligations: Analyzing your historical transaction data across all sales channels to pinpoint exactly where you have triggered physical or economic nexus.
Prepare Applications: Gathering your corporate documents, EIN, and officer details to complete state-specific applications accurately.
Submit Registrations: Filing the paperwork directly with each state’s Department of Revenue.
Track Status: Monitoring the state approval pipelines and securing your official tax permit numbers and login credentials.
2. Tax Return Preparation & Filing
Filing is a monthly operational hurdle. A provider takes over managing state portals entirely:
Data Reconciliation: Pulling data directly from Shopify, Amazon, and other marketplaces to clean, format, and reconcile gross sales against taxable transactions.
Return Preparation: Filling out the specific tax forms for each state, county, and local jurisdiction.
On-Time Submission: Executing the actual filing inside state portals according to your assigned monthly, quarterly, or annual schedules.
3. Automated Remittance
Full-service providers can also take care of the remittance part to complete the filing cycle:
Fund Management: Promptly calculating your total tax liabilities across all active states before the due dates hit.
Direct Remittance: Clearing the payment directly to each state treasury on your behalf, eliminating the need for your finance team to manage dozens of separate bank transfers or state-specific wallet setups.
4. Ongoing Compliance & Defense
State tax landscapes change constantly, and your business footprint scales dynamically. A provider ensures you’re always compliant and protected:
Nexus & Deadline Monitoring: Continually tracking your rolling sales volumes to alert you the moment you approach a threshold in a new state.
Regulatory Updates: Automatically adjusting backend systems when states change tax rates, product exemptions, or boundary lines.
Notice & Audit Support: Taking point if a state sends a confusing discrepancy letter or initiates an audit, interpreting the notice, pulling the audit data, and defending your returns.
How to Choose a Sales Tax Registration and Filing Service
Selecting the right partner to manage your sales tax footprint is a major operational decision. If you choose a vendor that only handles software calculations, your internal team will still have to do the heavy administrative lifting. Before you sign a contract with a registration and filing service, use this practical checklist to ensure they can fully manage your compliance lifecycle.
True Multi-State Registration
The provider shouldn’t just tell you where you need to register. They must actively prepare and submit corporate applications to secure your sales tax permits in the states covered by the provider’s service.
Continuous Nexus Monitoring
The service must track your trailing sales revenue and transaction counts across every state at regular intervals or in real time, depending on the provider’s monitoring capabilities, so a new filing obligation never blindsides you.
Hands-Off Filing and Remittance
Look for a partner that takes complete ownership of the filing process. They should automatically compile your returns, file them with the state, and remit the correct funds directly to state treasuries on your behalf.
Proactive Deadline Management
State tax calendars change constantly based on your rolling volume. Your provider must map out and manage your unique filing frequencies (monthly, quarterly, or annually) to help reduce the risk of missed deadlines.
Native Ecommerce Integrations
Your provider must have direct access to your active sales records. Whether you sell on Shopify, Amazon, eBay, or wholesale channels, they need to pull and reconcile all multi-channel data automatically.
In-House Human Tax Expertise
Automated software breaks when edge cases pop up, like complex product taxability rules or changing local jurisdictions. Ensure you have direct access to real sales tax experts who can guide your strategy.
Notice and Audit Support
State revenue departments regularly send confusing discrepancy letters. A true full-service partner steps in immediately to interpret the notice, pull historical data, and handle communications with state agents.
Back-Filing and Historical Resolution
If your brand has past unfiled periods or outstanding liabilities, your provider must be able to handle historical cleanups, calculate back taxes, and execute Voluntary Disclosure Agreements (VDAs).
Transparent, Predictable Pricing
Avoid platforms that hide your total cost behind opaque per-return fees, unexpected filing add-ons, or variable transaction spikes. Look for flat, predictable pricing that scales cleanly with your business growth.

What If My Business Is Already Behind on Sales Tax?
If you realize your brand has missed registrations or has been selling in states without a permit, don’t panic. You can resolve existing compliance issues safely by following a structured cleanup process:
Assess Total Historical Exposure: Calculate exactly how much tax your brand should have collected and remitted during the unfiled periods across each state.
Execute Historical Back-Filing: For short periods of noncompliance or minimal liabilities, registering normally and filing back returns is often the fastest way to get current.
Pursue a Voluntary Disclosure Agreement (VDA): If your brand has had material outstanding liabilities for several years, a formal VDA is your best tool. States will typically waive or drastically reduce penalties and limit the lookback period in exchange for you coming forward voluntarily.
Leverage Professional Assistance: Attempting to back-file or negotiate a VDA on your own can inadvertently trigger a broader corporate audit. Professional tax experts know exactly how to approach states anonymously, handle forensic data, and negotiate the lowest possible settlement.
Our team regularly steps in to clean up complex, historical sales tax exposure for scaling brands. We handle the data reconciliation, calculate your exact exposure, and execute the right resolution strategy so you can wipe the slate clean and scale forward without worry.
Frequently Asked Questions
1. Can someone register my business for sales tax?+
Yes. You can fully outsource this process to a full-service compliance provider or tax professional. They will review your sales data to identify your nexus footprints, gather your corporate details, and prepare and submit the state applications on your behalf.
2. Can someone file my sales tax returns for me?+

Learn more: Multi-State Sales Tax Filing Best Practices
3. Do I need a sales tax permit if I sell online?+
Yes, if you have established physical or economic nexus in that state. Online brands trigger physical nexus through inventory, warehouses, or remote staff, and trigger economic nexus once their sales revenue or transaction volume exceeds state-defined thresholds. Without establishing nexus, you’re generally not required to register for a sales tax permit.
4. Does registering an LLC automatically register me for sales tax?+
No. Forming or registering an LLC does not automatically register you for sales tax. You must complete a separate, dedicated application with that state’s Department of Revenue to secure your sales tax permit before you can legally collect tax from customers.
5. Can a sales tax provider register my business in multiple states?+
Yes. A true full-service provider can execute registrations across all US states where you have triggered nexus. They handle the distinct paperwork requirements for each state simultaneously, saving your operations team from having to manage dozens of separate state portals.
6. What’s the difference between sales tax software and a full-service provider?+
Sales tax software is generally a self-service tool that calculates sales tax rates at checkout and packages the data into report templates, leaving your team to handle the actual filing. A full-service provider handles the entire loop for you, taking over data reconciliation, registration, return filing, remittance, and state notice management.
7. Can someone help me if I’m already behind on sales tax filings?+
Yes. A specialized sales tax partner can perform historical data forensics, calculate your exact back-tax exposure, and execute the right resolution strategy. They can back-file old returns or negotiate a Voluntary Disclosure Agreement (VDA) to limit your penalties.

Sales tax compliance becomes more complicated as an ecommerce business expands into multiple states. Each state has its own tax rules, registration requirements, filing frequencies, and deadlines.The easiest way to manage multistate sales tax is to use a sales tax automation solution that integrates with your sales channels, calculates applicable taxes, and helps you prepare and file returns. A managed service can reduce manual work further by combining technology with professional support.However, automation alone doesn’t guarantee full compliance. Businesses must still identify where they have sales tax nexus, register where required, maintain accurate transaction data, and meet their tax obligations.This guide explains how sales tax automation works, what to look for in a solution, and how to decide between software and a managed service.
Why Manual Sales Tax Filing Puts Ecommerce Brands at Risk
Managing sales tax manually becomes harder as a business grows. Selling in several states can mean tracking multiple tax rates, registration requirements, return forms, and payment deadlines.Manual processes also create several risks:
Deadlines are missed. If you track due dates by state in a spreadsheet, it’s easy to lose track of which return is due next.
Rates are calculated wrong. States use differentsourcing rules, and local taxes may also apply. Applying the wrong rule can lead to
inaccurate collections and returns.
New nexus updates go unnoticed. Growing sales can trigger economic nexus midyear, creating unexpected sales tax collection and remittance obligations in new states. For the full picture, our guide to sales tax nexus explains exactly how physical and economic nexus work.
Errors multiply in scale. A small mistake on 50 orders a month is a pain. But the same mistake on 5,000 orders a month is a real liability that needs a solution.
In 2018, the U.S. Supreme Court’s decision in South Dakota v. Wayfair, Inc. allowed states to require certain out-of-state sellers to collect and remit sales tax without a physical presence. Each state sets its own economic nexus rules, including the applicable sales thresholds and measurement periods.As a result, businesses selling across state lines need a reliable way
to track changing obligations. Spreadsheets may work for a simple
operation, but they can become harder to maintain as sales channels and filing jurisdictions increase.
What Does Sales Tax Automation Actually Do?
Sales tax automation uses software to calculate applicable taxes, organize transaction data, and support compliance tasks across different jurisdictions.Depending on the solution, it can help businesses:
Calculate sales tax using current rates and applicable tax rules.
Connect transaction data from ecommerce platforms and marketplaces.
Monitor sales against economic nexus thresholds.
Prepare sales tax returns using transaction and liability data.
Track filing schedules and deadlines.
Submit returns electronically.
Coordinate tax payments and remittance.
Maintain reports and filing records.
Sales tax automation integrates with your sales channels, such as Shopify, marketplaces, or any order source, and uses transaction data to determine amounts owed, prepare tax returns, and handle filing and payments for each state.It’s a rules-based system that performs tasks a person would do manually, but without the exhaustion or errors. This reduces your team’s time on sales and use tax, lowers audit risk, and improves data integrity across ERP and billing systems.
How Automation Handles Multi-State Filing
The main advantage of automation is that it brings information from multiple sales channels into a more organized compliance process.Ohio, for instance, requires sales and use tax taxpayers to file electronically. Businesses can file and pay through the state’s OH|TAX eServices system. Washington also runs everything through its own My DOR portal.Most sales tax software can consolidate transaction data, apply relevant tax rules, and help prepare returns for registered jurisdictions. It can also help track filing deadlines, eliminating the need for the business to maintain separate calendars and spreadsheets.This reduces repetitive work, but the business still needs accurate data, correct tax settings, and a process for reviewing exceptions.
The Role of Accountants and Sales Tax Professionals
Automation handles many rules-based tasks, but some situations require professional judgment.Examples include determining whether a business has nexus in a state, reviewing unusual transactions, evaluating exemption documentation, interpreting tax notices, and addressing discrepancies in filed returns.An accountant or sales tax professional can help investigate these issues and determine the appropriate next steps.The most useful setup combines reliable software with human oversight for matters that require research, interpretation, or business-specific decisions.

Not every automation tool is built the same way, and the feature list can get long fast. Here’s what actually matters for an ecommerce brand:
Native platform integration. It should connect directly to Shopify, your marketplaces, and any other channels you sell through, without requiring you to manually export and upload files.
Nexus monitoring. The tool should flag when your sales in a new state are approaching or have crossed an economic nexus threshold, not just calculate tax in states you’ve already told it about.
A real filing calendar. Look for a tool that tracks every due date across every state you’re registered in, not just the states with the biggest volume.
Notice and audit support. When a state sends a letter, you want a system (and ideally a person) that catches it and responds, not one that leaves it sitting in an inbox.
Transparent, predictable pricing. Per-order or per-transaction fees can sneak up on you if there’s no cap. A flat or capped structure makes budgeting a lot easier.
How to Set Up Sales Tax Automation for Your Ecommerce Business
A reliable sales tax automation process starts with identifying obligations and ends with confirming that required returns have been filed and payments made.
Step 1: Evaluate Your Current Nexus Footprint
Before automating sales tax, determine where your business must register and collect sales tax.Sales tax nexus generally falls into two categories:
Physical nexus: A connection created by activities or presence in a state, such as employees, offices, inventory, or other qualifying business activities.
Economic nexus: An obligation that may arise when sales into a state exceed its applicable economic nexus threshold, even without a physical presence.
Economic nexus thresholds vary by state. Many states use a $100,000 sales threshold, but the rules differ in how sales are measured and which transactions count. Some jurisdictions may also apply transaction-count thresholds.Review sales by state, physical business activities, inventory locations, and applicable state rules. Do not rely on a single nationwide threshold to determine where your business must register.Once you identify your obligations, establish a process for monitoring changes as your sales and operations grow.
Step 2: Connect Your Ecommerce Platform
Integrate your sales tax software with the platforms and systems that contain your transaction data.Depending on your business, these may include Shopify, marketplaces, accounting software, enterprise resource planning systems, and other sales channels.The integration should capture the information needed for accurate calculations and returns, including transaction amounts, product details, shipping charges, refunds, and, where applicable, exemption information.Check whether the integration supports your specific platforms and whether it requires manual uploads or adjustments.Our post on whether Shopify collects sales tax explains the gap between what Shopify handles and what still needs to happen behind the scenes.
Step 3: Register in Required States
You can’t file (automated or not) in a state where you’re not registered. Once you’ve confirmed nexus in Step 1, register for a seller’s permit in each of those states before enabling automated filing.Skipping this step and trying to automate filing anyway is one of the most common and avoidable mistakes ecommerce brands make.
Step 4: Let Automation Handle Filing Payments
Once nexus is mapped, your platform is connected, and registrations are complete, automation can handle the repetitive tasks:
Retrieve transaction data periodically
Prepare the returns and submit them electronically
Ensure payments are made on time.
At this stage, your role shifts from filing to reviewing monthly reports and verifying their accuracy.
Sales Tax Automation Software vs. Managed Services
The easiest solution depends on how much work your business wants to handle internally.Sales tax software can automate calculations and selected compliance tasks. Managed services combine technology with additional support and may handle return preparation, filing, and other responsibilities on your behalf.
When is Automation Software Enough?
Software may be sufficient when your team has the expertise and time to manage registrations, review returns, resolve exceptions, and coordinate payments.It can be especially useful when your main challenge is calculating tax across sales channels or organizing data for your existing accounting workflow.Before choosing software, determine whether it includes the filing capabilities you need. A checkout tax calculator alone may not cover return preparation, filing, or remittance.
When Should You Consider a Managed Sales Tax Service?
A managed service may be a better fit when your team wants to reduce the time spent coordinating multiple jurisdictions and handling recurring compliance tasks.This can be particularly useful for growing ecommerce brands that sell across multiple states, handle complex transactions, or lack dedicated sales tax staff.Compare providers based on their supported jurisdictions, integration capabilities, filing responsibilities, payment process, notice support, and professional oversight.The goal is to establish a dependable process for managing the full range of sales tax obligations, not just automating calculations.
How Much Does Sales Tax Automation Cost?
Cost is where many ecommerce sellers get surprised, mostly because pricing in this space isn’t standardized. A few real numbers to work from:
State registration fees
These are usually the lowest-cost items, but they still add up across multiple states. Most states don’t charge for a seller’s permit. However, some states have seller’s permit fees that range from $5 to $100.
Software-only platforms
Sales tax automation pricing varies by provider, order volume, number of filing jurisdictions, and included services.
Some plans charge a monthly subscription fee, while others add fees for returns beyond the included filing credits. Compare the total cost of calculations, filings, registrations, and support before choosing a solution.
Full-service providers
These providers, merging automation with real accountant oversight, usually have different pricing models. They are often offered as a flat monthly fee or based on your order volume. This approach is appealing to most businesses because it avoids layering a subscription fee on top of per-filing charges and additional notice-handling costs.The true comparison isn’t only the sticker price but also what’s included. A cheaper plan that lacks notice response or audit support might end up costing more when issues arise for the first time.
Common Mistakes Ecommerce Brands Make When Automating Sales Tax
A few patterns show up again and again once brands start automating:
Automating before registering. Automation can file only in states where you’re already registered. Turning it on before you’ve completed registrations creates more problems.
Assuming the software catches new nexus on its own. Some tools flag approaching thresholds; many don’t. If no one’s actively monitoring your sales growth by state, you can cross a threshold without anyone noticing for months.
Ignoring notices because “the software handles it.” Automation files returns; it doesn’t automatically resolve a letter from a state department of revenue. Those still require a human response.
Feeding messy data into the system. Refunds, exemption certificates, and marketplace-collected sales must be reconciled before being included in your filings. Garbage in, garbage out still applies here.
It’s important to recognize that this isn’t solely a software issue.The Streamlined Sales Tax helps participating states simplify aspects of sales tax administration. Its Certified Service Provider program allows eligible sellers to work with approved providers for certain tax calculation and filing services.This is the main reason a formal certification program for automated tax systems was created.
Frequently Asked Questions
1. What is sales tax automation and how does it work for ecommerce businesses?+
It integrates with and manages your sales channels to calculate the tax owed per transaction based on the transaction’s source, and to prepare and file returns with the appropriate states.
This streamlines the manual process of generating reports and submitting filings for each state.
2. Can I automate sales tax filing across all U.S. states?+
Some providers support filing across many state and local jurisdictions,
but coverage varies. You must identify your obligations, complete
required registrations, provide accurate data, and confirm which returns and services the provider supports.
3. Do I still need an accountant if I use sales tax automation software?+
Yes. Automation efficiently manages repetitive calculations and filing tasks, but exemption questions, audit responses, and notices from state agencies often require a knowledgeable person familiar with your business details.
4. How do I know if my ecommerce business has nexus in a state before automating?+
Review your sales and transaction numbers by state against each state’s economic nexus thresholds, and verify whether you have any physical presence, such as inventory, employees, or a warehouse, in that state.
5. What happens if my automated filing has an error or gets audited?+
Automation helps minimize errors but cannot completely prevent them, particularly if the initial data was flawed. If a state raises an issue or initiates an audit, it’s beneficial to have a provider or accountant who can respond directly, rather than leaving you to interpret the state’s notice on your own.
6. How long does it take to set up sales tax automation for an online store?+
Setup time depends on registration volume, with approvals taking anywhere from days to several weeks. After completing the registrations, linking your platform and enabling automated filing is typically swift.
7. Is automated sales tax filing compliant with every state’s requirements?+
Automation follows state filing rules, but compliance depends on accurate data and active nexus registrations. The tool follows the rules, but proper setup remains your responsibility or your provider’s.
Is Sales Tax Automation Right for Your Ecommerce Business?
Managing sales tax across multiple states involves more than calculating the correct rate at checkout. Businesses must understand their nexus obligations, register where required, maintain accurate transaction records, and meet return deadlines.TaxHero combines sales tax automation with professional support to help ecommerce businesses manage these responsibilities.Its services support tax calculations and filing, while sales tax professionals help with nexus analysis, registrations, notices, and compliance questions.For businesses evaluating a solution, it is important to understand how these capabilities fit their existing operations and which responsibilities remain with their team.Not sure where your business stands?

Online marketplaces have become a major sales channel for ecommerce businesses. If you sell products through platforms such as Amazon, eBay, Etsy, Walmart, or TikTok Shop, those platforms may act as marketplace facilitators. A marketplace facilitator helps facilitate sales between sellers and customers. Depending on the platform, it may list products, process payments, collect sales tax, and assist with shipping. Marketplace facilitator laws determine when these platforms must collect and remit sales tax on behalf of sellers. However, using a marketplace does not automatically eliminate a seller’s own sales tax obligations. Sellers may still need to determine where they have economic nexus, register for sales tax, collect tax on direct sales, file returns, and maintain compliance records. This guide explains how marketplace facilitator laws work, how they affect sellers, and how marketplace sales can affect economic nexus.
What are Marketplace Facilitator Laws?
The United States has implemented marketplace facilitator laws to simplify sales tax collection from online marketplace transactions.Instead of requiring every third-party seller to collect and remit sales tax on marketplace transactions, these laws generally place the responsibility for collection and remittance on the marketplace facilitator.For example, if a seller makes a taxable sale through a marketplace such as Etsy or eBay and the marketplace must collect tax under the applicable state law, the marketplace generally collects and remits the tax for that transaction.Marketplace facilitator laws help states collect sales tax from marketplace transactions while reducing the number of individual sellers responsible for collecting and remitting tax on those sales.However, the seller may still have other sales tax obligations, including registration, filing, reporting, or collecting tax on sales made outside the marketplace.
Do All Marketplace Facilitators Collect Sales Tax?
No. Whether a marketplace must collect and remit sales tax depends on applicable state law and whether the marketplace meets the requirements to be a marketplace facilitator in that state.
For example, a marketplace may be required to collect sales tax once it meets a state’seconomic nexusor marketplace facilitator threshold. The specific requirements vary by state.
Sellers should therefore check the rules that apply to the marketplace and state involved rather than assume that every marketplace transaction is automatically covered.
How do Marketplace Facilitator Laws Affect Sellers?
Marketplace facilitator laws can reduce the seller’s responsibility for collecting and remitting sales tax on covered marketplace transactions. However, they do not necessarily remove all of the seller’s sales tax obligations. Depending on the state, a marketplace seller may still need to:
File a zero or informational return when the marketplace collects and remits the tax.
Register for a non-reporting tax status when the state offers it.
Collect, file, and remit sales tax on taxable sales made outside the marketplace.
Do Marketplace Facilitator Sales Count Toward Economic Nexus?
It depends on the state.Some states include marketplace facilitator sales when calculating a seller’s economic nexus threshold. Other states exclude marketplace sales when the facilitator collects and remits sales tax on the seller’s behalf.This means sellers should not assume that marketplace sales always count toward an economic nexus threshold. They also should not assume that marketplace sales are always excluded.Treatment can vary by state, type of sale, and whether the marketplace facilitator collects and remits the applicable tax.For this reason, marketplace sellers should track marketplace sales separately from sales made through their own websites and other sales channels.
Marketplace Facilitator Nexus vs. Seller Economic Nexus
The terms marketplace facilitator nexus and seller economic nexus are related but different concepts.Marketplace facilitator nexus determines when a marketplace facilitator must collect and remit sales tax on marketplace transactions.Seller economic nexus determines when an individual seller’s economic activity in a state creates a sales tax obligation.A marketplace can therefore collect sales tax on a seller’s marketplace transactions, while the seller may still have separate registration or filing obligations.Reaching an economic nexus threshold also does not automatically mean that the seller must collect tax on marketplace transactions. In states with marketplace facilitator laws, the facilitator may remain responsible for collecting and remitting tax on covered marketplace sales.
Which States Count Marketplace Sales Toward Economic Nexus?
States take different approaches to marketplace sales when calculating economic nexus thresholds.Some states include marketplace sales in the seller’s threshold calculation. Others exclude marketplace sales when the marketplace facilitator collects and remits the tax.The following table provides a high-level view of the treatment. We advise sellers to verify the current rules with the applicable state tax authority because economic nexus rules can change.
However, if all sales are made exclusively through a collecting marketplace facilitator, individual sellers are not required to register with the ARSSTC (Submit a Marketplace Seller Affidavit)
Included towards the threshold for individual sellers. A statutory deduction for marketplace sales is allowed if the facilitator collects and remits the tax
Included towards the threshold for individual sellers. However, if all sales are exclusively made through a marketplace facilitator, the individual seller is not required to register.
Excluded from the threshold for individual sellers
Note: “Yes” and “No” refer to whether marketplace sales are included in the individual seller’s economic nexus threshold calculation under the applicable rules. They do not determine whether the marketplace facilitator must collect sales tax. Some states have additional conditions or exceptions.
Example: How Marketplace Sales Can Affect Economic Nexus
Suppose a retailer makes $80,000 in sales through its Shopify store and $50,000 in sales through Amazon.The retailer sells to customers in a state with a $100,000 economic nexus threshold.If the state includes marketplace facilitator sales in the threshold calculation, the retailer may have $130,000 in qualifying sales and exceed the threshold.If the state excludes marketplace facilitator sales when the facilitator collects and remits the tax, the retailer may have only $80,000 in qualifying sales for that calculation.The seller should therefore check the state’s current rules before determining whether marketplace sales count toward the economic nexus threshold.
Why Sellers Should Track Marketplace Sales Separately
Even when a marketplace collects and remits sales tax, sellers should maintain records of their marketplace transactions. Many states encourage businesses to keep records for 3 to 4 years.Tracking marketplace sales separately can help sellers:
Determine whether marketplace sales count toward an economic nexus threshold.
Identify when registration may be required.
Separate marketplace sales from direct website sales.
Complete required sales tax returns.
Document sales activity during a sales tax audit.
Monitor changes in economic nexus exposure across states.
Keeping marketplace and non-marketplace sales separate also makes it easier to determine which sales remain the seller’s responsibility.
Marketplace Facilitator Tax Laws in Different States
While the general concept behind marketplace facilitator laws is straightforward, their requirements vary across states.Each state can establish its own rules for marketplace facilitators, including the sales threshold, transaction threshold, registration requirements, and marketplace transactions covered by the law.Refer to the table below for each state’s marketplace sales threshold.
NOTE: Marketplace facilitator rules and economic nexus requirements can change. Always verify the current requirements with the applicable state tax authority.
US Marketplace Sales Tax Compliance
Marketplace facilitator laws handle a lot of the heavy lifting, but they don’t give you a free pass on sales tax. Even if Amazon, Walmart, or Etsy collects and remits tax on your behalf, you’re still responsible for keeping your business compliant. Here’s exactly what compliance looks like for you.
1. Track Your Direct Sales Separately From Marketplaces
If you sell through your own website in addition to platforms like Amazon, you must keep these channels separated. Marketplace facilitator laws only cover transactions on their specific platforms. For any direct sales you make through your own Shopify or WooCommerce store, you’re entirely responsible for calculating, collecting, and remitting the sales tax yourself.
2. Keep Immaculate Records
You need to maintain detailed records of every single transaction, regardless of where it happened. Your records should clearly show the gross sales amount, the specific marketplace used, and the tax collected by that platform. If an auditor ever knocks on your door, you must be able to prove that the marketplace actually collected the tax on those specific orders.
3. File Your Returns and Reconcile the Data
Many states still require you to file a sales tax return even if 100% of your sales go through a marketplace. When you file, you’ll usually report your gross sales first. Then you’ll deduct marketplace sales so that your net taxable sales reflect what you actually owe. Reconciling your records ensures you aren’t paying tax twice or underreporting your revenue.
4. Maintain Proper Registrations
Don’t rush to close your sales tax permits just because a marketplace handles collections. In states where you have physical inventory, employees, or meet the direct sales thresholds, you must maintain an active sales tax registration. Closing a permit prematurely can lead to severe penalties and compliance headaches down the road.
Which States Do Not Have Marketplace Facilitator Laws?
All 45 states with a statewide general sales tax, plus Washington, D.C., have marketplace-facilitator collection rules. The NOMAD states: Alaska, Delaware, Montana, New Hampshire, and Oregon do not have a statewide sales tax. Alaska does not have a statewide sales tax but allows local jurisdictions to impose sales taxes and marketplace-facilitator rules.Because sales tax rules differ by state and local jurisdiction, marketplace sellers should review the applicable requirements where their customers are located.
Know Your Nexus As A Marketplace Seller
Marketplace sellers should monitor their economic nexus status even when a marketplace collects sales tax. To determine whether you have established economic nexus:
Option A: Trace your sales history. Review sales by state and separate marketplace transactions from direct sales. Check whether the state includes or excludes marketplace sales from its threshold calculation.
Option B: Use sales tax software. TaxHero’s Nexus Analysis can help identify states where your business may have established sales tax nexus.
Option C: Work with a sales tax professional. A sales tax professional can help review nexus exposure and determine whether registration or other compliance action is required.
If a seller discovers that it may have established nexus in a state, it should review the state’s registration, filing, and collection requirements as soon as possible.
The 2026 Trend: Why States are Dropping the 200-Transaction Rule
Economic nexus rules keep changing as states update their sales tax laws.Several states have removed or changed the traditional 200-transaction threshold. This means sellers should not assume that the same revenue and transaction thresholds apply in every state. Marketplace sellers should review current state requirements regularly, especially when their sales volume changes or they expand into new states.
Does Marketplace Facilitator Collection Mean You’re Fully Compliant?
No, it doesn’t automatically mean you’re fully compliant. While marketplace facilitator laws take a massive burden off your shoulders, relying entirely on Amazon, Walmart, or Etsy to handle your sales tax compliance is a dangerous mistake. The marketplace only handles taxes on transactions processed through its platform. The rest of your business compliance is still your responsibility.
Where You Still Have Tax Obligations
Even if a marketplace handles 90% of your sales, you’re still on the hook for several critical compliance areas:
Direct website sales: Your own online store’s entirely separate from 3rd-party platforms.
Sales through other channels, such as wholesale orders, social media shopping links, or invoicing clients directly, aren’t covered by marketplace laws.
Registration requirements: You must still register for tax permits in states where you meet physical or economic thresholds.
Filing and reporting requirements: Most states expect you to file a zero-dollar or informational return showing your marketplace revenue.
Recordkeeping and reconciliation: You’ve got to prove to auditors exactly which transactions were taxed by the marketplace.
A Practical Example
Imagine you run a growing ecommerce brand. You sell your product on Amazon and also run your own Shopify store. Amazon automatically calculates, collects, and remits the sales tax for every order placed on Amazon. However, Amazon doesn’t look at your Shopify store. For your direct website sales, you’re the one who must track nexus, set up tax collection at checkout, and file returns to pay the state. If you ignore your Shopify sales, you’re exposed to major tax penalties.
The Practical Takeaway
Marketplace facilitator laws reduce some of your day-to-day compliance work, but they don’t eliminate it. Think of platforms as helpers for a specific slice of your business, while you remain the ultimate compliance officer for your entire company.
When Does an Ecommerce Business Need Sales Tax Compliance Help?
It depends on your business layout. Not every ecommerce business needs a dedicated sales tax compliance service. If you’re just starting out and only sell in your home state, you can handle the paperwork on your own.However, as your business grows, manual tracking quickly turns into a major headache.
When Help Becomes Highly Valuable
You’ll likely need to look for professional or automated help when your business hits these milestones:
Selling across multiple states: Managing different tax rules and deadlines across state lines gets complicated fast.
Selling through multiple channels: Combining marketplace sales with your own direct website creates messy data.
Managing multiple tax registrations: Tracking active permits across states takes too much time.
Handling recurring filing obligations: Filing monthly or quarterly returns across multiple states can eat up your calendar.
Growing your transaction volume: More orders mean a higher risk of costly calculation mistakes.
Facing frequent rule changes: State tax laws change constantly, and keeping up with them’s a full-time job.
Hitting resource limits: Your internal team doesn’t have the time or background to manage tax audits.
What a Compliance Service Actually Does
A dedicated service or software automates the trickiest parts of compliance. At a high level, they handle your registrations, ensure accurate tax calculation at checkout, manage your filing schedules, and monitor your ongoing economic nexus exposure.
A Simple Decision Framework
To figure out where you stand, look at your current complexity:
Manual management is enough if: You have a simple business model, low order volume, and limited tax obligations in just one or two states.
Automation or professional support makes sense if: You run a growing, multi-state, multi-channel business where a single compliance error could cost you thousands in penalties.
Frequently Asked Questions
1. Is Amazon a marketplace facilitator?+
Yes. Amazon acts as a marketplace facilitator for qualifying transactions and may collect and remit sales tax on behalf of third-party sellers.
However, Amazon’s sales tax collection does not necessarily eliminate the seller’s registration or filing obligations.
2. Is TikTok a marketplace facilitator?+
TikTok Shop can act as a marketplace facilitator for transactions made through its marketplace.
The specific tax collection responsibilities depend on the applicable state and the requirements that apply to the platform.
3. Do I need to pay taxes if I sell on Shopify?+
Selling through Shopify does not automatically make Shopify the marketplace facilitator responsible for collecting and remitting your sales tax.
In general, sellers using Shopify may remain responsible for collecting and filing their own sales tax.
Learn more →Does Shopify Collect Sales Tax?
4. Why is Shopify not a marketplace facilitator?+
Shopify primarily provides ecommerce infrastructure that allows businesses to operate their own online stores. A marketplace facilitator, by contrast, facilitates transactions between marketplace sellers and customers through a marketplace platform.
This distinction affects who may be responsible for collecting and remitting sales tax under state marketplace facilitator laws.
5. Do I need to collect sales tax if I sell online in different states?+
Not necessarily. Selling online to customers in different states does not automatically mean you need to collect sales tax in every state.
You generally need to collect sales tax when you have sales tax nexus in a state and are required to collect tax there. Nexus can be created through physical presence, economic activity, or other state-specific rules. Marketplace facilitator laws may also affect how you tax and report sales.
6. Does a marketplace facilitator handle all sales tax compliance?+
No, a marketplace facilitator only handles a limited scope of sales tax compliance. While marketplace collection reduces your workload, it only covers orders placed on that specific platform. It doesn’t handle compliance for independent or direct orders.
7. If a marketplace collects sales tax, do I still need to register?+
It depends on your business activities and the specific state rules.While the marketplace handles collection, states consider your overall footprint to determine registration requirements. You’ll generally still need to register if:
Marketplace sales count: Depending on the state, they may count toward your economic nexus threshold. Revisit the complete state-by-state table for your reference.
The state requires informational returns: Many states expect you to register and file a report of your gross sales, even if the marketplace pays the tax.
You have physical nexus: Storing inventory in a marketplace warehouse or hiring remote staff in a state usually triggers a physical registration requirement.
You sell through your own website: If your direct website sales cross a state’s economic threshold, you must register to collect tax on those non-marketplace orders.
8. What sales tax responsibilities remain with marketplace sellers?+
Even when a marketplace handles tax collection, the ultimate compliance responsibility for your business stays with you.Marketplace sellers remain fully responsible for:
Direct sales: Tax on orders from your own site (like Shopify).
Other channels: Wholesale deals or direct billing.
Registrations: Keeping active permits where you have nexus.
Filings: Submitting state returns, even if they’re zero-dollar reports.
Recordkeeping: Proving to auditors that the marketplace collected the tax.
9. Do I need a service to handle sales tax compliance for my ecommerce business?+
Not necessarily. Some ecommerce businesses can manage sales tax compliance themselves, especially if they only operate in a few states.
A sales tax service can help when you have nexus in multiple states, sell through multiple channels, or need help with registration, tax calculation, filing, and remittance.

Sales tax can be one of the most confusing parts of running an ecommerce or online business. Rules vary by state, local jurisdiction, product, service, and the customer’s location.
This guide explains what sales tax is, how it works, when you need to collect it, what nexus means, how to register and file, and how to stay compliant across multiple states.
Key Takeaways
Customers generally pay sales tax, and sellers collect it.
There is no federal U.S. sales tax. States and local jurisdictions establish their own rules.
Rates vary by location. A customer’s combined rate can include state, county, city, and special district taxes.
Not every product or service is taxable. Taxability depends on the state and, in some cases, the local jurisdiction.
Nexus and taxability are separate questions. Having nexus in a state does not automatically make every sale taxable.
Online businesses can have obligations even without a physical location in a state. Economic nexus can create an obligation based on sales activity.
Registration generally comes before collection. Once a business determines that it has a sales tax obligation, it may need to register with the state before collecting tax.
Sales tax rules and rates change. Businesses selling in multiple states need an ongoing process for monitoring nexus, taxability, rates, registration, and filing requirements.
What is Sales Tax?
It is a consumption tax charged on certain purchases of taxable goods and services. The buyer generally pays the tax, the seller collects it, and the seller remits it to the applicable state or local tax authority.
Sales tax is an indirect tax because the business collecting it generally does not bear the economic cost. Instead, the business collects the tax from the customer and passes it on to the government.
The United States does not have a nationwide federal sales tax. Instead, sales tax is imposed primarily by states and local jurisdictions such as counties, cities, and special taxing districts.
This is why the sales tax rate and rules can change depending on where a transaction takes place.
Who pays sales tax?
The customer generally pays sales tax as part of the purchase price.
Who collects sales tax?
The seller generally collects sales tax from the customer when the seller is legally required to do so.
Who receives sales tax?
The seller generally remits the tax to the appropriate state or local tax authority.
Is sales tax the same in every state?
No. States have different sales tax rates, taxability rules, exemptions, nexus rules, registration requirements, and filing obligations.Some states also use taxes that operate differently from a traditional sales tax. Arizona imposes a Transaction Privilege Tax (TPT), Hawaii imposes a General Excise Tax (GET), and New Mexico imposes a Gross Receipts Tax (GRT). These taxes are often discussed alongside sales tax because they apply broadly to business transactions and affect ecommerce sellers.
How Does It Work?
A typical transaction involves four basic steps:
Determine whether the seller has nexus in the jurisdiction.
Determine whether the product or service is taxable.
Determine the applicable rate and sourcing rules.
Collect, report, and remit the tax when required.
For example, an ecommerce business may sell a taxable product to a customer in another state. If the business has sales tax nexus in that state and the product is taxable there, the business may need to collect the applicable sales tax from the customer.
How Is It Calculated?
Sales tax is computed as a percentage of the sales price, with rates varying by jurisdiction, and some local governments also collect their own. To calculate your tax, you must list the price of your taxable product, including any taxable shipping charges. After that, determine the combined sales tax rate that applies to the transaction’s location. Then convert the state’s combined sales tax rate to decimal form.Once you convert the rate to decimal format, multiply your product’s price by the decimal. The result is your estimated sales tax for that transaction.
Here’s the simplified formula breakdown:Price of Goods + Shipping Fee xState Sales Tax Rates +Local Sales Tax Rates= Your Total Sales Tax
Example Scenario:
You’re selling a taxable product worth $50 with a $10 shipping fee. This brings your total sale price to $60.
The product was shipped to New York City, New York, where shippingis taxable. The combined state, county, city, and other local rates in New York City, New York, are 8.875%.
Convert the state’s combined sales tax rate into decimal format. 8.875% turned into decimal format is: 0.08875
Now, multiply your sale price by the decimal form of the combined city, county, and state sales tax rate. 60 x 0.08875 is = $5.325 When rounded off, this amount becomes = $5.33
Finally, add everything to your base sales price to collect sales tax accurately. [Product Price] $50 + [Shipping Fee] $10 + [Calculated Sales Tax] $5.33 TOTAL = $65.33
To simplify the calculation, you can also use TaxHero’s FREE Sales Tax Calculator.As shown in the example above, the combined rate refers to the combined state and local (i.e., County, City, District) sales tax rates.You must also understand that the business responsible for collecting the tax must ensure that the correct amount is collected, reported, and remitted under the applicable rules.
State and Local Sales Tax: What Is The Difference?
A state sales tax is imposed by the state government.
A local sales tax is imposed by a local jurisdiction, such as a county, city, or special taxing district.
The rate charged to a customer can therefore be higher than the state’s base rate.
For example, a state may have a statewide sales tax rate while a particular city or county adds additional local taxes.
Businesses should not assume a state’s published rate automatically applies to every transaction.
The applicable combined rate depends on the jurisdiction and the rules governing the transaction.
Are All Goods and Services Subject To Sales Tax?
Not every product or service is taxable in every state.State law determines taxability, which can vary significantly between jurisdictions.
For example:
A product may be taxable in one state but exempt in another.
A service may be taxable in one state but not another.
A product may be exempt from state tax but subject to a local tax.
Digital products and software may be subject to different tax rules than physical goods.
Certain purchases may qualify for specific exemptions.
This creates an important distinction: Nexus determines whether a business may have a sales tax obligation in a jurisdiction. Taxability determines whether a particular transaction is subject to tax.
Having nexus does not automatically mean every sale the business makes is taxable.
Before collecting sales tax, businesses should determine both where they have an obligation and what they must tax.
Which States Collect and Do Not Collect?
As of 2026, 45 states and the District of Columbia impose a statewide general sales tax or comparable broad-based consumption tax. Many states also allow local governments to impose additional sales taxes. However, the following eight states do not impose local sales taxes:
New Jersey does allow certain local sales taxes. For example, local sales taxes apply to certain sales in Atlantic City and Cape May County. The state also has an Urban Enterprise Zone (UEZ), where qualified businesses can charge a reduced state sales tax rate of 3.3125% on certain qualifying sales.Meanwhile, the states that do not collect sales tax are called the NOMAD states, a name derived from the first letter of those states. The NOMAD states do not impose a statewide general sales tax, and those states are:
NOTE: Alaska allows its local jurisdictions to impose and collect local sales tax. Oregon also imposes a Corporate Activity Tax (CAT), which is measured on a business’s commercial activity and is separate from a retail sales tax.

When to Collect Sales Tax?
A business generally needs to collect sales tax when:
It has sales tax nexus in a jurisdiction; and
The transaction involves a taxable product or service; and
The business must collect tax in accordance with that jurisdiction’s rules.
This is especially important for ecommerce businesses because selling to customers in another state can create tax obligations even when the business has no office or store there.Before collecting tax, businesses generally need to determine whether they have a nexus and complete any required registration. Collecting sales tax without the appropriate sales tax permits is not allowed and could result in non-compliance penalties.
What is Sales Tax Nexus?
A sales tax nexus is a sufficient connection between a business and a state that can create a sales tax registration and collection obligation. Once a sales tax nexus is created, your business generally must register in the state and begin collecting and remitting sales tax. But how can you identify once a sales tax nexus exists for your business? Two types of sales tax nexus determine your business’s presence in a state: physical nexus and economic nexus.
Physical Nexus
Physical nexus generally occurs when a business has a sufficient physical presence or business activity in a state.Common examples can include:
A physical store or office
A warehouse
Inventory stored in the state
Employees working in the state
Sales representatives or other business representatives
Certain contractors or agents
Other activities specified under state law
The exact rules differ by state. For ecommerce businesses, inventory can be particularly important. Using a third-party logistics provider, fulfillment center, or marketplace fulfillment service may create physical nexus depending on the state’s rules and the circumstances.
Economic Nexus
Economic nexus is a sales tax connection created when an out-of-state business reaches a state’s specified level of economic activity, typically measured by sales revenue, transaction volume, or both. This matters for online sellers because a business can establish nexus without a traditional physical location in the state.Economic nexus thresholds differ by state and can change over time. For example, Alabama uses a $250,000 sales threshold under its current rules and has eliminated its former 200-transaction threshold.Other states use different thresholds, measurement periods, and rules. To check each state’s economic nexus threshold, read: Ultimate Guide to Understanding Economic Nexus
Do Online Sellers Have to Collect Sales Tax?
Online sellers do not automatically have to collect sales tax on every sale.An online seller generally needs to collect sales tax when it has the required nexus in the customer’s state, the transaction is taxable, and the state requires collection.This means an ecommerce business may have sales tax obligations in multiple states even if it operates from a single location.Marketplace sellers also need to understand how marketplace facilitator lawsinteract with their own nexus and registration obligations.A marketplace may collect and remit tax on a seller’s behalf, but marketplace collection does not necessarily eliminate the seller’s own nexus, registration, or reporting responsibilities.
Who Should Register for Sales Tax
Businesses that have a sales tax collection obligation generally need to register with the relevant state before collecting sales tax.This can affect:
Businesses operating inside a state: A business with a physical presence, such as a store, office, warehouse, inventory, or employees, may establish physical nexus and therefore have a sales tax registration obligation.
Remote and ecommerce businesses: An out-of-state seller can establish economic nexus by exceeding the applicable threshold or otherwise meeting a state’s requirements.
Once an obligation is identified, the business may need to:
Determine its registration requirement.
Register for a sales tax permit.
Configure its sales tax collection system.
Begin collecting when required.
File sales tax returns.
Remit the tax collected.
Continue monitoring its obligations.
How to File Sales Tax Returns
Once you register your business in a state, you become responsible for collecting and remitting sales taxes accurately and on time. If it’s your first time filing a sales tax return, a general rule is that each state has different procedures, requirements, and due dates.In today’s digital age, where most things can be done online, we can generalize the steps for filing sales tax returns online into this standard process:
Step 1: Prepare your ecommerce tax report (e.g., tax report from Shopify) – Make sure that your report is accurate and contains all the information you need to file your sales tax return correctly.
Step 2: Search for your state’s filing website – For example, Colorado instructs filers to use “Revenue Online” for a simplified filing process. Usually, the filing website is the same page when you register a business online. However, other states could have unique links that may direct you to.
Step 3: Log in using your sales tax account – Generally, this account refers to your state sales tax account, which is typically created when you register your business online.
Step 4: Locate the “File Return” option – Different state websites have different layouts, but since your goal is to file a return, most of them should have this option, or it may be worded differently.
Step 5: Begin filing your sales tax return – Make sure you select the correct filing period and enter your data based on your tax report. Usually, there’s an option to save your return as a draft and continue later if you can’t complete it immediately.
FILING TIP: A few states offer a discount for those who file their returns on time. This is commonly referred to as a “timely filing discount.” However, some states may use different terms, like Nevada’s “Collection Allowance.” To claim the discount and help save, ensure you always file on time.
How to Stay Compliant with Sales Tax Regulations
Given the complexity of U.S. sales tax rules, staying compliant can feel like a difficult endeavor. To ensure your business complies with the various laws, here are 7 critical things every business should know to stay compliant.
Keep track of your nexus — It’s important to know where you stand in the “invisible bridge” that connects your business to a state’s economic system. Once you cross that bridge and establish a nexus, you’ll have to comply with tax regulations. Failure to comply can result in penalties that harm your business.
Check every state’s specific rules – Never assume that one state’s sales tax rule is the same as another’s. Even if some rules seem common across many states, it’s still best to navigate safely by verifying each state’s specific rules.
Always keep records – Your transactions are proof of your business activities. Once your business establishes a nexus, a good practice for staying compliant is to maintain records. These records will help your business stay clear during audits and avoid penalties.
Register your business – Once a nexus is established, don’t delay your business’s registration. Otherwise, you risk being liable for non-compliance. If you need help registering your business, you can let TaxHero do it for you or read our state-by-state guides.
Identify your product’s taxability – The taxability of goods and services varies depending on the state’s specific rules and guidelines. You must know where your product is subject to taxation and where it is exempt.
Calculate with precision – Even a small difference in the report can cost you an audit. This is why tip #3 is crucial: your records can also help you accurately calculate your total sales tax. Always be mindful of local, district, and local option taxes that may apply to your transactions.
Remit sales tax on time – After registering your business, make sure you never miss your returns and their filing due dates. Dates vary across states, so always check the correct due dates for the states you are selling in.
NOTE: You can also consider outsourcing sales tax compliance by choosing the most fitting tax software for you. With TaxHero, we take care of all your compliance needs so you don’t have to.
What Happens If You Don’t Collect or Remit?
Failure to comply can result in penalties, interest, assessments, and other enforcement actions.The consequences depend on the jurisdiction, the type of violation, the amount of tax involved, and other circumstances.Potential issues can include:
Because penalties vary by state, businesses should check the rules of the applicable state rather than assuming a single penalty structure applies nationwide.
Frequently Asked Questions
1. I am an online seller. Do I have to collect sales tax on all the salesI make?+
No. Online sellers do not have to collect sales tax on every sale. Generally, collection is required when the seller has the necessary nexus in the applicable state, the transaction is taxable, and the seller is responsible for collecting the tax under that state’s rules.
2. What does sales tax holidays mean?+
A sales tax holiday is a limited period during which states allow tax-free purchases of specific items. States typically offer this to encourage consumer spending. Common types include:
Energy Star Appliance – This holiday encourages buyers to purchase energy-efficient appliances such as refrigerators and washers.
Emergency Preparedness – Common in states that are prone to hurricanes, such as Alabama, Florida, and Texas.
Back-to-School – The most common holiday, typically occurring between late July and August. This holiday usually exempts goods like clothing, footwear, school supplies, and sometimes even personal computers or tablets.
3. Are products like food, clothing, SaaS, and shipping taxable?+
Grocery food is often exempt, but taxability varies by state and by the type of food. Prepared food, restaurant meals, candy, beverages, and other food products may be taxable. Clothing is considered tangible property and may be taxable or non-taxable, depending on the state. Many states offer partial exemptions from sales tax for clothing that they deem necessary. SaaS taxability varies by state. Some states tax SaaS and other electronically delivered products or services, while others exempt them or apply different rules. Businesses should check the rules in each state where they have an obligation.Sales tax on shipping varies by state; some states impose it, while others don’t. There are also unique conditions that vary by state. For example, in Florida, shipping is exempt if the shipping option is optional and the buyer has a pick-up option. Additionally, the invoice must state the shipping charges separately for the exemption to be valid.
Meanwhile, in states like New York and Texas, businesses generally charge customers taxes on shipping charges by default, even if they itemize the goods separately.
The Bottom Line
Sales tax is not one nationwide tax with one set of rules. It is a collection of state and local tax systems with different rates, nexus rules, taxability rules, registration requirements, filing schedules, and exemptions.For an ecommerce business, compliance comes down to answering four questions:
Where do I have sales tax nexus?
What products or services are taxable in those jurisdictions?
How much sales tax should I collect?
When and where do I need to file and remit it?
As your business grows across states and sales channels, monitoring those answers becomes increasingly important.TaxHero helps ecommerce businesses monitor sales tax obligations, identify potential nexus, and manage multi-state sales tax compliance.Explore TaxHero’s sales tax solutions now or book a free demo today.
Economic nexus determines when an online business must register, collect, and remit sales tax in a state based on its sales activity there.
You can establish economic nexus even without a physical location, employees, or inventory in a state. Each state sets its own economic nexus threshold and rules for determining which sales count.
For ecommerce businesses selling across multiple states, tracking these rules is essential. Crossing a state’s economic nexus threshold can create sales tax registration and collection obligations.
What is Economic Nexus?
Economic nexus is a sales tax connection created when a business reaches a state’s required level of economic activity. States generally measure economic activity using sales revenue, transaction volume, or both. The specific threshold varies by state.
Economic nexus became widely adopted after the U.S. Supreme Court’s 2018 decision in South Dakota v. Wayfair, Inc. The decision allowed states to require certain out-of-state sellers to collect sales tax based on their economic activity in the state, even without a physical presence.
Today, most states with a sales tax have economic nexus rules for remote sellers.
Economic Nexus vs. Physical Nexus
Economic nexus is based primarily on economic activity in a state. Physical nexus is based on a business’s physical connection to the state.Physical nexus can arise from activities such as:
Maintaining an office, store, or warehouse
Storing inventory in the state
Having employees or representatives in the state
Using certain third-party fulfillment arrangements
Conducting other activities that create a physical presence
A business can establish sales tax nexus through physical presence, economic activity, or both.
How Does Economic Nexus Work?
States set their own economic nexus thresholds. A threshold may be based on:
A dollar amount of sales
A number of transactions
A combination of sales and transactions
For example, a state may require an out-of-state seller to register after reaching $100,000 in sales during a specified measurement period. Another state may require $100,000 in sales or 200 transactions.Some states have removed their transaction-count thresholds. Recent changes include Louisiana in 2023, Alaska and Utah in 2025, and Illinois and Kentucky in 2026. This means ecommerce businesses cannot rely on one nationwide rule when monitoring economic nexus.
What Sales Count Toward Economic Nexus?
States do not all use the same definition of sales when measuring economic nexus.Depending on the state, the calculation may include:
Gross sales
Taxable sales
Retail sales
Gross receipts
Sales of tangible personal property
Certain marketplace sales
Other specified receipts
A business should therefore use each state’s rules when calculating its economic nexus exposure.Simply adding total sales by state may not produce the correct result.
Economic Nexus Measurement Period
States also use different measurement periods.Common approaches include:
Previous calendar year
Current or previous calendar year
Previous 12 months
A rolling 12-month period
Four preceding sales tax quarters
A state-specific period
For example, Connecticut uses a 12-month period ending September 30, while New York uses the preceding four sales tax quarters.Understanding the measurement period is important because reaching a threshold depends not only on how much you sell but also on when the state measures those sales.
Economic Nexus Thresholds by State in 2026
The following table provides a state-by-state overview of economic nexus rules for 2026.Because states can change their thresholds and calculation rules, businesses should verify the applicable state guidance before registering or making collection decisions.
Note: Thresholds and measurement rules can change. Verify state-specific requirements before relying on this table for registration or collection decisions.The NOMAD states: Alaska, Delaware, Montana, New Hampshire, and Oregon do not impose a general statewide sales tax. Alaska has no statewide sales tax, but participating local jurisdictions may impose sales tax under the Alaska Remote Seller Sales Tax Commission framework.
How To Know If Your Business Has Economic Nexus
To determine whether your business has economic nexus, review your sales activity in each state where you have customers.Use this process:
Identify your sales by state: Break down your sales based on the destination state.
Review the state’s measurement period: Determine whether the state looks at the previous calendar year, current year, previous 12 months, or another period.
Check the applicable threshold: Compare your qualifying sales and transaction volume with the state’s threshold.
Review marketplace sales: Determine whether marketplace sales must be included in the state’s economic nexus calculation.
Determine your obligations: If you meet the applicable threshold, review the state’s requirements for registration, collection, filing, and remittance.
Do Marketplace Sales Count Toward Economic Nexus?
Marketplace sales can count toward economic nexus even when the marketplace facilitatorcollects and remits the sales tax.However, states treat marketplace sales differently.Some states include marketplace sales when determining whether a seller has exceeded its economic nexus threshold. Other states exclude certain marketplace sales or treat them differently.This creates an important distinction:Marketplace collection responsibility and economic nexus are not always the same thing.A marketplace may collect and remit sales tax on a transaction while the seller’s marketplace sales still contribute to its economic nexus calculation.For this reason, marketplace sellers should track marketplace sales separately from direct website sales and review the rules for each state.
Do I Need to Collect Sales Tax If I Sell Online in Different States?
Not automatically.Selling to customers in another state does not by itself mean you must collect that state’s sales tax. You generally need a sales tax obligation in that state when your business has a taxable product or service and has established sales tax nexus there.Sales tax nexus can arise through physical presence or economic activity.For remote ecommerce sellers, economic nexus is often the key consideration. If your qualifying sales or transactions exceed a state’s threshold, you may need to register, collect sales tax, and file returns under that state’s rules.However, marketplace facilitator laws can shift the responsibility for collecting and remitting tax on marketplace transactions to the platform.That does not necessarily eliminate the need to evaluate your nexus.
Economic Nexus for Shopify Stores
Shopify stores can create economic nexus when their sales into a state exceed that state’s threshold.A Shopify merchant selling nationwide should monitor sales by state rather than assuming that Shopify’s tax settings determine whether the business has nexus.A typical monitoring process includes:
Tracking sales by destination state.
Identifying states where sales are approaching the nexus threshold.
Reviewing what each state includes in its calculation.
Checking whether marketplace sales are included.
Registering when required.
Configuring sales tax collection after registration.
File and remit collected tax according to the state’s schedule.
This becomes more complicated when a business sells through both Shopify and marketplaces such as Amazon, eBay, Etsy, or Walmart Marketplace.
Economic Nexus for Marketplace Sellers
Marketplace sellers can establish economic nexus based on their sales activity even when the marketplace handles sales tax collection.For example, a seller may generate enough marketplace sales to exceed a state’s economic nexus threshold. The marketplace may then collect and remit tax on those transactions, but the seller may still need to determine whether registration or other reporting requirements apply.If the seller also operates its own Shopify store, it must consider both sales channels when monitoring nexus.
Economic Nexus for Different Business Models
Economic nexus also affects businesses selling SaaS, software, digital products, and other services.However, reaching an economic nexus threshold does not automatically mean that every sale is taxable.States differ in how they tax software, SaaS, digital products, and services.A business should therefore evaluate two separate questions:
Has the business established nexus in the state?
Are its products or services taxable in that state?
A business can have nexus without owing sales tax on every type of sale.
What Happens After You Establish Economic Nexus?
Crossing an economic nexus threshold can create several compliance obligations.Depending on the state, you may need to:
The exact timing of these obligations varies by state.Do not assume that crossing a threshold has the same collection start date in every state.
What to Do If You Fall Below the Threshold?
Some states have removed their transaction-count thresholds. This means a business that previously established nexus based only on transaction volume may no longer meet the state’s current threshold.However, falling below a threshold does not automatically cancel an existing registration or filing obligation.If you believe you no longer have nexus, check the state’s rules for closing or maintaining the account before stopping collection or filing.
Common Economic Nexus Mistakes
Assuming every state uses a $100,000 threshold
Many states use $100,000, but some use higher thresholds. California, New York, and Texas, for example, use $500,000 sales thresholds under their current rules. Alabama and Mississippi use $250,000 thresholds.
Using the same measurement period for every state
States use different measurement periods. A business can therefore cross a threshold in one state while remaining below the threshold in another.
Ignoring marketplace sales
Marketplace sales may count toward economic nexus even when the marketplace collects the tax.
Assuming marketplace collection eliminates nexus
Collection responsibility and nexus are separate questions.
Waiting until the end of the year to check nexus
Some states use current-year sales or rolling periods. Waiting until year-end can cause a business to miss an obligation.
Treating nexus and taxability as the same thing
Establishing nexus does not automatically mean every product or service is taxable.
Frequently Asked Questions
1. How do economic nexus laws apply to me if I run a seasonal business?+
Seasonal businesses are not exempt from these laws. Accurately calculate your sales and transactions during your operating months to comply with the respective state’s thresholds and criteria.
2. How does economic nexus relate to other forms, like click-through or affiliate nexus?+
Economic nexus focuses on sales and transaction thresholds, while click-through and affiliate nexus focus on relationships with affiliates in a state. Therefore, depending on your business model, you might need to comply with one or more nexus regulations.
3. What actions should I take if I realize my business has unknowingly established an economic nexus in a state?+
Suppose you find out you’ve unknowingly established an economic nexus. In that case, consult a tax expert promptly to understand the steps needed for compliance and to correct any past discrepancies.

Sales tax nexus is a rule you can’t ignore as an ecommerce business. It’s the legal link between your business and a specific state that requires you to collect sales tax from customers living there. Whether you’re shipping orders from home or selling nationwide, crossing these state lines can change your tax responsibilities overnight. To secure your business, you must understand what creates a nexus and what to do next. You can cross the line by storing inventory in an out-of-state warehouse or by simply hitting a state’s dollar sales threshold. As sales tax rules vary across the country, this guide breaks down the complex laws for U.S. ecommerce business owners.
What is Sales Tax Nexus?
Sales tax nexus is a connection between a business and a statethat determines whether the business must collect sales tax from customers in that state. Think of it as an invisible bridge connecting your business to places where you have many customers.Understanding this connection helps you operate correctly and stay on the right side of the law regarding sales tax collection, supporting a smooth, successful operation. In short, nexus determines when your business has a legal sales tax obligation in a specific state. If your commercial activities cross a state’s specific threshold, you can no longer ignore its local tax authorities. You become legally responsible for managing the entire compliance lifecycle within that jurisdiction.Once a nexus is established, you must complete 4 critical steps to stay compliant:
Register for a sales tax permit with the state before collecting
Collect the correct sales tax amount at checkout
Prepare and file regular sales tax returns before deadlines
Remit the collected sales tax to the state government
What Is Economic Nexus and How Does It Affect Ecommerce Businesses?
Economic nexus is a tax connection triggered purely by your sales revenue or order volume within a state, without needing any physical presence there. This modern rule originates from the landmark 2018 Supreme Court decision: South Dakota v. Wayfair, Inc., which allowed states to impose a sales tax obligation on remote online sellers. Today, if you ship enough orders to buyers in a specific state, you can easily cross the economic threshold and must legally collect its local sales tax.
Revenue, Transactions, and Measurement Periods
States generally measure your economic presence using two specific types of thresholds:
Total sales/revenue: A dollar amount of sales sent into the state (most commonly $100,000, though larger states like California set it at $500,000).
Number of transactions: A specific volume of individual orders (most commonly 200 transactions).
NOTE: As of 2026, multiple states have removed the transaction threshold for their economic nexus standards. To determine if you have crossed these lines, you must look at a state’s measurement period. Most states evaluate your sales data using either the previous or current calendar year, while others look at a rolling 12-month window.
What Happens When You Exceed a Threshold
The moment your ecommerce store exceeds a state’s threshold, your legal obligations change. You must start doing the following right away:
Register for a sales tax permit with that state
Set up tax collection at checkout
Begin filing regular returns
Here’s a sample scenario: An ecommerce brand is based in Ohio, but they ship orders nationwide. Over the year, their total sales to customers in Georgia steadily climb until they exceed $100,000 in sales, officially crossing Georgia’s economic nexus threshold. Despite having no physical office or inventory in Georgia, they now have economic nexus in the state and must immediately start collecting Georgia sales tax. NOTE: Collecting sales tax without an official sales tax permit is considered illegal. Please register your business the moment you establish a nexus. This will also help prevent accumulating non-compliance penalties.
Economic Nexus Thresholds by State
Because each state has its own sales tax laws, the rules for crossing an economic nexus threshold vary widely. As an ecommerce seller, you must actively monitor both your state-by-state sales revenue and your overall transaction counts to ensure you don’t accidentally cross a legal line.While the standard threshold for many states is $100,000 in sales, some larger states demand much more. Other states still enforce a strict 200-transaction limit. For instance, you can trigger nexus in California only after crossing $500,000 in sales. In Georgia, crossing $100,000 in sales or making 200 transactions into the state triggers an immediate tax obligation.Tracking state-by-state sales tax rules can be complicated, especially when they may change at any time. For a complete, up-to-date breakdown of every jurisdiction’s specific thresholds, you can check out our state-by-state economic nexus table in another guide.
What Activities Can Create Sales Tax Nexus?
Businesses can create sales tax nexus in 2 ways.
1. Economic Nexus Triggers
Economic nexus is established based on varying criteria.
It depends on the amount of sales your business generates
Or the number of transactions you have in a state
Sometimes, BOTH thresholds must be crossed, like in Connecticut and New York
2. Physical Nexus Triggers
Let’s visualize for a moment – perhaps you have a welcoming storefront, a bustling warehouse, or even an employee based in a specific state. Any of these scenarios create a physical nexus. It forms a concrete bridge between your business and the geographical boundaries of that state, a link that comes with its set of responsibilities. Here are the main ways you can have a physical nexus:
Storing inventory in a location, like a third-party fulfillment center (3PL), or maintaining a warehouse of your own
Employing staff or sales representatives in the state, including affiliates
Regular physical presence through business activities such as meetings or providing services
Attending temporary trade shows, storing digital goods on localized servers, or traveling out-of-state to perform services can quickly cross the line into physical nexus.
Marketplace Facilitator Laws
Marketplace facilitator laws have significantly changed how sales tax responsibilities apply to many online sellers. These laws require large ecommerce platforms to collect and remit sales tax on behalf of third-party sellers using their marketplaces. As a result, the burden of collecting sales tax may shift from the individual seller to the platform itself. However, marketplace facilitator laws don’t always eliminate nexus considerations.
Sellers may still have nexus obligations: Even when marketplace platforms collect tax, sellers may still establish nexus through their own activities, such as storing inventory or operating independent online stores.
Multi-channel selling creates additional responsibilities: Businesses that sell through multiple channels, such as their own website and third-party marketplaces, may still need to track nexus and collect sales tax for non-marketplace sales.
Marketplace sales are included in the threshold count: Some states include facilitated marketplace sales toward your economic nexus threshold count. Even if businesses sell exclusively through marketplaces, they can still establish nexus.
How Do You Monitor Sales Tax Nexus Across Multiple States?
Nexus monitoring is an ongoing operational task for every growing ecommerce business. As your sales volumes fluctuate and state rules constantly shift, a footprint that’s perfectly compliant today could easily cross a legal threshold tomorrow. A multi-layered tracking strategy is one of the best ways to actively monitor your nexus.
1. Centralize and Track Sales by State
To monitor your footprints accurately, you must be able to pull your historical sales data and filter it by the customer’s shipping state. Your tracking must look at the full picture of your brand’s footprint, combining revenue from your independent storefront (like Shopify) alongside sales from all different ecommerce channels and marketplaces (like Amazon, eBay, or Etsy). Even if a marketplace automatically collects the tax for you, as stated above, many states still count those marketplace transactions toward your overall economic threshold.
2. Monitor Evolving State Thresholds and Rules
Once you have your multi-channel sales data organized by state, regularly compare it against each jurisdiction’s specific economic limits and designated lookback periods. This requires close attention, as state tax departments frequently update regulations. For example, staying compliant means tracking the ongoing legislative trend of states updating or eliminating transaction thresholds to simplify rules for small businesses.
3. Leverage Automation Software
Manually cross-referencing your real-time sales spreadsheets against multiple sets of state tax laws is a recipe for human error. Most successful ecommerce brands delegate this burden to specialized sales tax automation software or professional sales tax service providers. These platforms securely connect to your storefronts, automatically aggregate your multi-channel sales data, and send you instant alerts the moment you approach a state’s compliance boundary. With TaxHero, we combine software with the skills of real, professional accountants. If you need help tracking your nexus across states, you can book a free demo with us today.
What Happens After You Establish Sales Tax Nexus?
Once a business establishes nexus in a state, it typically becomes responsible for several tax compliance obligations. These responsibilities ensure that the business collects and reports sales tax correctly within that jurisdiction. Failing to respond promptly after establishing nexus can result in penalties or additional tax liabilities. After nexus is established, businesses usually need to:
Register for a sales tax permit: Before collecting sales tax, businesses must register with the state’s Department of Revenue and obtain a valid sales tax permit.
Collect sales tax from customers: Once registered, businesses must charge the applicable state and local sales tax rates on taxable products or services sold to customers in that state.
Configure your ecommerce store: Set up your online store settings to ensure it accurately collects the right amount of sales tax. Undercharging may result in penalties, forcing you to pay the undercharged amount out of pocket.
Understand different taxability rules: Rules, rates, and exemptions varyby state. Local regulations may also vary. Each jurisdiction may impose unique rules, such as adding special district taxes to certain sales.
Know the sourcing rules: States follow either an origin-based or destination-based sourcing rule. For most remote sellers, transactions often follow a destination-based sourcing rule. This means sales tax is calculated based on the buyer’s location.
File sales tax returns: Businesses must regularly report collected sales tax to the state. All applicable details must be accurately reported, including exempt sales. Filing frequency may vary by state and company sales volume.
Complete the remittance: Filing your returns is not the end of the compliance cycle. To complete it, you must remit the collected sales tax to the state authorities.
Ongoing compliance maintenance: Actively track your business’s compliance standing so you don’t fall behind ever-changing sales tax rules.
Maintain tax records: Proper documentation of sales transactions, collected taxes, and filed returns is essential for maintaining compliance during audits or regulatory reviews.
Understanding these steps helps businesses transition smoothly into compliance after creating nexus.
What’s the Easiest Way to Calculate and File Sales Tax Across Multiple States?
The easiest way to calculate and file sales tax across multiple states is to use sales tax automation software oroutsource the entire process to a professional compliance service provider. These compliance tools seamlessly connect to your online store, instantly computing the exact tax rates at checkout and automatically submitting your returns on time without any manual data entry. The ideal solution depends on your preferred approach.
Why Multistate Sales Tax Is So Complicated
Handling this process by hand is incredibly difficult because the US lacks a single, unified tax system. Instead, ecommerce sellers must navigate a confusing patchwork of local laws, including:
Diverse Rates and Sourcing: Depending on the state’s sourcing rules, the tax rate is based either on where your business is located (origin-based) or where your buyer lives (destination-based). Some states also use a hybrid approach, combining both depending on the transaction rules.
Product Taxability: Rules change drastically depending on what you sell. A product that is fully taxable in one state might be exempt in another.
Varying Frequencies and Deadlines: States assign your filing schedules (monthly, quarterly, or annually) based on your sales volume. Their filing deadlines rarely align, forcing you to track dozens of different due dates every single month.
Registration and Remittance: You must formally register for a unique sales tax permit in each state before you can legally collect a single dime. Once collected, you must log into each state’s portal to remit the funds securely.
3 Ways to Manage Your Compliance
Choosing the right compliance strategy depends heavily on your business structure and preferred solutions. Before deciding how to approach compliance, consider your current business size, the number of states where you have nexus, your total monthly sales volume, your mix of sales channels, and how much hands-on management you want to deal with.

Frequently Asked Questions
1. How do I know which states I have nexus in?+
To determine if you have an economic nexus in a state, you’ll need to examine that state’s specific sales and transaction thresholds. These criteria may vary between states. At TaxHero, we offer services like nexus checking to guide you through this process and help you stay on the right side of the law.
2. What are the penalties for not complying with sales tax nexus regulations?+
Non-compliance can result in various penalties, including fines and interest on unpaid taxes. In extreme cases, it might lead to legal action. The specifics can depend on the state’s regulations.
3. Are there certain states that do not impose a sales tax?+
Yes, there are a few states, specifically Delaware, Montana, New Hampshire, and Oregon, where no state sales tax is collected. While Alaska doesn’t impose a state sales tax, it allows local governments to charge a local sales tax. These states may still have other forms of business taxes in place.
4. Do I need to register in every state where I sell?+
No, you only need to register for a sales tax permit in states where your business has officially established a physical or economic nexus. A business with physical nexus or another qualifying connection may have to register even if its sales remain below the state’s economic nexus threshold.
5. Can sales tax software handle multistate compliance?+
While sales tax software is highly effective at automating real-time calculations and generating your required tax forms, it generally remains a self-service tool. You are still ultimately responsible for reviewing the system’s accuracy, fixing formatting errors, and manually approving final filings and payments unless you opt into their automated filing add-ons.

Selling online and growing your business is straightforward until you deal with U.S. sales tax. Instead of focusing on daily business, you now have to worry about compliance every time you sell to customers in different states.
The biggest hurdle is economic nexus, a law that requires you to register, collect, and remit sales tax in another state once you hit a specific sales threshold, even if you operate from home.
Managing this on your own is nearly impossible because the nation has more than 11,000 sales tax jurisdictions, each with its own changing rules, rates, and deadlines. As the paperwork piles up, many businesses wonder whether someone else can handle sales tax registration and filing, and whether their ecommerce business needs a dedicated compliance service.
This guide answers those questions by breaking down how sales tax for ecommerce businesses works, what tasks you can hand off or outsource, and how to choose the right sales tax solution.
Can Someone Handle My Sales Tax Registration and Filing for Me?
Yes, you can outsource your sales tax registration and filing to professional sales tax compliance service providers. Handing off these responsibilities allows you to offload the entire administrative burden to tax experts or automated tools. A full-service tax provider typically monitors your economic nexus thresholds across different states, registers your business with state revenue departments, accurately calculates taxes at checkout, and prepares and files your recurring tax returns on time. This approach especially benefits fast-growing ecommerce businesses, multichannel sellers managing orders across platforms (like Shopify, Amazon, and eBay), and international brands selling to U.S. customers. If your business is rapidly scaling and you spend more time tracking tax districts than marketing your products, outsourcing helps keep you compliant without draining internal resources. A common mistake growing ecommerce businesses make when outsourcing is ending up with sales tax software or tools that still make them do the manual work, such as:
Tracking changing rates and rules
Registering for permits in states
Filing and remitting returns on time
TaxHero combines sales tax software features with professional human tax services to take sales tax off your hands. Schedule a free call with our CEO, Lahari, an expert CPA, to find out how we can help your ecommerce business with sales tax.
Do I Need a Sales Tax Compliance Service for My Ecommerce Business?
Not every ecommerce business necessarily needs a sales tax compliance service right away. Whether you need a professional service depends entirely on your business setup. For guidance, consider the following:
Your current sales volume
Where your customers are located
How much time you’re willing to spend on manual paperwork
Handling compliance on your own is manageable if your business is in its early stages. For example, many states use a $100,000 sales threshold, but economic nexus rules vary. Check each state’s current rules before determining whether registration is required. Doing it yourself is also doable if you sell exclusively through marketplaces like Amazon, eBay, or Walmart, where marketplace facilitator laws typically handle the calculation, collection, and remittance at checkout. Professional support becomes especially valuable when sales tax compliance becomes a major liability as your business expands past economic nexus thresholds in different states.
What Does an Ecommerce Sales Tax Compliance Service Handle?
An ecommerce sales tax compliance service handles all of your sales tax work from start to finish, reducing the administrative work involved in sales tax compliance. Instead of leaving you to track thousands of changing tax laws on your own, a full-service provider handles every step for you. Below is a list of services a professional sales tax compliance provider offers:
Nexus Monitoring
Nexus monitoring tracks your sales volume across different states to pinpoint exactly where you legally owe tax. Compliance services connect directly to your shopping carts to calculate your revenue and transaction counts in real time. This automated tracking flags precisely when your business is approaching or has crossed an economic nexus threshold, giving you early warning before compliance liabilities accrue. TaxHero also offers a free nexus analysis for all our clients. Book a demo here.
Sales Tax Registration
Sales tax registration processes and requirements vary by state. With complex conditions and time-consuming steps, professional compliance services handle the entire application process. They’ll gather your corporate documentation, submit the paperwork to the relevant state authorities, and secure your official sales tax permit IDs.
Sales Tax Collection & Calculation
Sales tax collection and calculation applies the exact, real-time tax rate to a customer’s shopping cart at checkout. Since rates vary down to the specific street address, sales tax compliance service providers typically integrate directly with platforms like Shopify or WooCommerce. The system instantly verifies the buyer’s location, references current state and local tax rules, and applies the correct calculation to the order. Usually, this is done using sales tax software or automated tools developed by the service provider.
Sales Tax Return Preparation
Sales tax return preparation consolidates your raw transactional data into state-approved reporting formats. At the end of each tax cycle, a compliance service compiles your gross sales, taxable sales, and exemptions across all channels. The service breaks down your collected tax by state, county, city, and special district layers, helping ensure your figures reconcile with your sales records. Depending on your chosen service provider, returns may be prepared with automated tools or by a team of tax professionals.
Sales Tax Filing
Sales tax filing submits your completed tax return forms directly to each state’s revenue department. Each state enforces its own filing schedule, ranging from monthly to annual. Unique online portals and submission rules may also change these filing schedules. Professional sales tax compliance services manage the filing cycle automatically, uploading your finalized returns through secure state gateways ahead of every deadline. This also lets you take advantage of timely filing discounts in some states.
Sales Tax Remittance
Sales tax remittance securely transfers the tax money you collect from customers to the state. Failing to send these funds on time triggers heavy financial penalties. Sales tax compliance services automate this transfer by securely routing the exact tax liabilities from your business account straight to the appropriate state tax authority, completing the filing and remittance process.
Compliance & Deadline Monitoring
Compliance and deadline monitoring provides continuous oversight against changing sales tax rates, new laws, and filing dates. These regulations are never permanent, as states periodically adjust sales tax boundaries, alter exemption rules, and shift filing frequencies as your business grows. Ongoing monitoring and support from compliance service providers ensure your automated systems and filing routines adjust immediately to new updates without interrupting your daily business operations.
How Ecommerce Sales Tax Compliance Works
Managing your sales tax doesn’t have to be complicated. The entire process follows a simple, cyclical path. Here is the step-by-step summary of how sales tax compliance works for ecommerce businesses from start to finish:
Determine where you have nexus: Track your physical presence and sales volumes to find exactly which states you legally owe tax to.
Identify what you need to collect: Check state laws to see if your specific products or services are taxable or exempt.
Register where required: Apply for sales tax permits with state revenue departments before collecting any tax when you cross economic nexus thresholds.
Configure sales tax collection: Turn on and test the tax calculation settings inside your store checkout (like Shopify or WooCommerce).
Track transactions: Organize your sales data and distinguish marketplace-facilitated transactions from direct sales. Account for marketplace-collected tax and any state rules that require marketplace sales to be included in nexus calculations.
Prepare returns: Clean up your seasonal sales numbers and fill out the official breakdown forms required by each state.
File returns: Submit your completed paperwork using the correct return forms through the state online portal before the deadline.
Remit collected tax: Securely transfer the sales tax you collected from buyers to the state treasury.
Maintain ongoing compliance: Keep monitoring changing state sales tax laws, moving deadlines, and new sales spikes as your brand grows.
Managing Sales Tax Compliance In-House vs. Outsourcing
The main difference between managing sales tax in-house and outsourcing it is who performs and manages the compliance work. With an in-house approach, the business handles monitoring obligations, maintaining registrations, preparing and filing returns, tracking deadlines, and managing related compliance issues. With an outsourced service, the provider handles the specific tasks included in the service agreement. Full-service providers take over everything or most of the tasks, depending on your preferred setup.

Can Ecommerce Platforms Handle Sales Tax Compliance?
No, standard ecommerce platforms generally cannot handle your sales tax compliance on their own or without specific configurations. A common mistake new online sellers make is assuming a platform manages their entire tax burden just because it calculates tax at checkout. To protect your business, you must understand the difference between these 3 options:
Ecommerce Platform: Platforms like Shopify or WooCommerce can calculate and collect tax with the right configuration settings, but they don’t track your sales limits, register your permits, or file your returns.
Sales Tax Software: Tax software can automate calculations, nexus monitoring, reporting, and, depending on the product, filing and remittance. The level of automation varies by provider.
Sales Tax Compliance Service: A fully managed service combines technology with professional support and can handle tasks such as nexus monitoring, registration, return preparation, filing, and other compliance work under the service agreement.
In summary: Your standard ecommerce store platform will happily collect tax for you, but it leaves you on your own for sales tax compliance requirements. You’ll still do the manual work without outsourcing.

When Should You Outsource Ecommerce Sales Tax Compliance?
Deciding when to hand off your sales tax comes down to balancing your business complexity with your available time. Use this quick framework to evaluate where your ecommerce business stands today:
When to consider internal management
Few tax locations: You only sell to customers in your home state or a couple of nearby areas.
Simple sales setup: You sell a single type of product through just one online storefront.
In-house tax skills: You have an internal accountant with the time and knowledge to handle monthly forms.
When to consider outsourcing
Rapid growth: Your sales are expanding quickly into new regions across the country.
Multiple states: You have crossed economic nexus limits in several states, triggering multi-state tax duties.
Multiple channels: You sell across various platforms at the same time, like Shopify, Amazon, and eBay.
Heavy filing schedules: You’re facing constant monthly or quarterly filing deadlines.
No internal experts: You lack dedicated tax help and lose hours to paperwork instead of growing your brand.
Growing confusion: You find changing state tax laws difficult to manage and worry about costly audit mistakes.
Common Ecommerce Sales Tax Compliance Mistakes
Sales tax compliance mistakes can lead to unexpected back taxes, interest charges, and costly audit penalties. Even well-intentioned online brands frequently fall into common traps because state rules are constantly moving. To keep your business protected, make sure you are avoiding these six critical compliance pitfalls:
Failing to register after establishing nexus: A major mistake is continuing to sell in a state after you cross its economic nexus threshold without applying for a permit. Collecting sales tax without a permit is illegal. Failing to collect it also warrants additional non-compliance penalties.
Missing filing deadlines: States enforce strict monthly, quarterly, and annual due dates. Missing a deadline by even a single day can trigger automatic financial penalties and wipe out any discounts the state offers for on-time filing.
Assuming marketplace collection eliminates all obligations: While platforms like Amazon or Etsy automatically collect tax at checkout, they do not completely eliminate your duties. Economic nexus can still be triggered if a state includes marketplace sales toward your threshold. Selling outside marketplace facilitator platforms may also create separate sales tax obligations.
Incorrectly configuring tax collection: Relying blindly on standard platform settings without updating your tax zones can lead to under-collecting or over-collecting tax. If you don’t collect enough tax at checkout, you’ll have to pay the remaining balance out of your own pocket.
Failing to file required returns: Some business owners assume that if they had zero sales in a specific state during a slow quarter, they don’t need to file a return. In reality, failing to file a required “zero return” still results in non-filing penalties and system notices.
Outdated sales tax accounts: Failing to update your tax accounts when your business moves locations, changes ownership structures, or switches corporate names can stall your filings and result in suspended tax accounts.
Frequently Asked Questions

A sales tax compliance service manages your sales tax responsibilities from start to finish depending on your agreed setup. This often includes real-time sales tracking, registering for state permits, calculating tax at checkout, preparing and submitting returns, and securely paying the collected funds to the government.
6. Is sales tax software enough for an ecommerce business?+
It depends on your business structure. Generally, sales tax software is still often a do-it-yourself automated tool. However, businesses remain responsible for ensuring their tax obligations, registrations, configurations, and filings are accurate.

Best Sales Tax Software by Ecommerce Use Case
Best For Growing/Mid-Sized Ecommerce Businesses
Growing or mid-sized ecommerce businesses should look for software that can help their business automate sales tax processes as they expand into additional states and sales channels. TaxHero, Zamp, and Kintsugi are the top options for growing ecommerce businesses. These platforms provide different levels of automation and professional support at a more accessible cost than many enterprise-focused solutions.
Best For Multi-State Ecommerce Businesses
Managing sales tax across multiple states requires robust compliance tracking as economic nexus thresholds are met. Businesses navigating multi-state obligations often evaluate platforms like Avalara, Zamp, and Taxwire to handle complex multi-jurisdiction calculations, state registrations, and recurring filing schedules.The right solution depends heavily on whether your organization needs lightweight dashboard software or an enterprise-grade tax engine to support expanded geographic footprints.
Best For Fully Managed Sales Tax Compliance
Brands looking to completely offload their sales tax burdens frequently turn to fully managed compliance solutions. Specialized services, including TaxHero and Zamp, along with other top-tier managed platforms, aim to automate calculation processes while utilizing specialized support systems to handle filings and state notices.This operational approach allows businesses to outsource technical tax administration so internal teams can focus entirely on core growth strategies.
Best For Ecommerce Marketplaces
Selling across diverse digital channels introduces unique compliance challenges due to differing marketplace facilitator laws. Merchants operating on multiple platforms typically look for software with native integrations for major networks like Shopify and Amazon.Solutions like Numeral, Kintsugi, and Avalara are designed to sync this multichannel transaction data cleanly, ensuring accurate reporting across all active sales platforms.
Avalara vs TaxJar vs TaxHero
Choosing the right platform depends entirely on how your business sells products and how much help you want with your taxes.Avalara operates as a high-powered corporate engine built for massive scale, specializing in heavy-duty tools that also handle international taxes such as VAT, cross-border shipping rules, and custom database connections for large enterprises. TaxJar functions as a user-friendly software built for scaling independent online sellers who want full visibility over their tax liabilities. The platform specializes in organizing multichannel transaction data into clean reports and providing automated tools for store owners who prefer to manage their own filings. Meanwhile, TaxHero merges sales tax software features and compliance services by offering a completely done-for-you experience.Instead of giving you tools to manage yourself, TaxHero combines advanced automation tools with a dedicated team of real sales tax professionals, effectively acting as your personal, outsourced sales tax compliance department.
How to Choose Sales Tax Software for Your Ecommerce Business
While there are several excellent sales tax software brands to choose from, the right product still depends on what your business needs. To choose the right sales tax automation software for your business, consider these 7 crucial factors:
Coverage: Do you sell internationally? Or do you plan to keep your sales within the U.S. in the meantime? Some sales tax software supports global coverage; some do not. Look for the one that fits your business’s coverage.
Future Plans: If your business is steadily growing, you can invest in more advanced software that covers your future sales tax requirements rather than sticking to simple software with limited features.
Human Support: Good software will not function without real human support. Even if you are an independent business requiring minimal assistance, you will need a supportive team to handle your sales tax concerns, especially during the onboarding process, which generally requires technical knowledge.
Accounting Expertise: Advanced AI sales tax software isn’t always guaranteed to work on its own, as technology can still have its hiccups. Therefore, you should check your brand’s background. Is it composed of accounting experts that you can directly turn to for assistance?
Features Compatibility: Some software offers extensive features that may not always be beneficial for your business, such as providing GST or VAT compliance services, which may not be useful for businesses only selling within the U.S.
Audit Support and Representation: Search for software that keeps everything in one place for you. In the event of an audit, you’ll have easy access to all the information you need to support yourself in an audit. Some brands will also represent your business directly, providing financial security and peace of mind.
Automated Services vs. Done-For-You Service: In general, plenty of sales tax software tools can do automatic calculations and tracking. However, not all of them file and remit sales tax for you, including registering your business. If you’re searching for software that manages all your compliance requirements, look for software that offers a done-for-you service, like TaxHero or Zamp.

The software actively monitors your economic nexus thresholds, calculates precise rooftop-level tax rates at checkout, tracks exemptions, and generates or submits your recurring tax returns to state authorities.
5. Do ecommerce businesses need sales tax software?
Ecommerce businesses may benefit from sales tax software as they expand into multiple states, sales channels, and marketplaces. Sales tax software can simplify calculation, nexus monitoring, registration, and filing, reducing the manual work involved in managing sales tax obligations.
Does Shopify collect sales tax for you? Yes, it calculates and collects sales tax from your customers at checkout. However, it does not remit those taxes to the government on your behalf.
Shopify’s automated system determines the correct sales tax rate based on your customer’s shipping address and applies it to each transaction, making the collection process straightforward.
This guide explains how to identify where you owe sales tax (nexus), set up Shopify Tax, and understand the difference between collecting and remitting sales tax to help you stay compliant with state and local regulations. By the end, you’ll have a clear understanding of your responsibilities and the tools available to help you manage sales tax effectively.
Does Shopify Collect Sales Tax?
Shopify serves as the platform that automates sales tax calculations and collection at checkout, but it is the taxing authorities, such as state and local governments, that set the rules and receive the remitted taxes.
As the “merchant of record,” the seller is ultimately responsible for tax compliance, including registering for permits, filing returns, and remitting collected taxes. However, as of 2026, Shopify Tax is a comprehensive service that includes Shopify Tax Automated Filing as an integrated feature for eligible U.S. states. This facilitates both the filing and remittance of collected sales tax on your behalf, streamlining compliance and reducing manual effort.
What is Shopify Tax?
Shopify Tax is a specialized tool designed to streamline sales tax compliance for U.S.-based merchants. By analyzing customer addresses and specific product categories, the feature automatically calculates and applies the most accurate tax rates at checkout.
It also includes a liability insights tool, which monitors your sales data to help you identify where your business may have reached nexus. While the system provides the data and calculations needed, it is not automated by default; merchants must manually enable tax collection for specific jurisdictions within their admin settings.
The service is accessible to all Shopify users, offering a cost-effective solution for growing businesses. It is free of charge for your first $100,000 in annual U.S. sales each calendar year. Once you surpass that threshold, Shopify applies a small calculation fee to orders in states where tax collection is active: 0.35% for standard plans and 0.25% for Shopify Plus users.
Shopify Tax vs. Manual Tax
When managing sales tax on Shopify in the U.S., merchants can choose between Shopify Tax (Shopify’s automated tax solution) and a manual tax setup. Here’s how they compare:
Shopify Tax: Shopify’s automated tax engine for U.S. merchants, offering advanced features like smart product categorization, address-level rate accuracy, and automated filing in supported states.
Manual Tax: Merchants manually configure tax rates and rules for each state and locality, update rates as laws change, and handle all compliance steps without automation.
The right choice depends on your store’s size, complexity, and desire for automation. Here’s a side-by-side comparison:

Understanding Sales Tax Nexus: When Are You Required to Collect
While Shopify makes it easier to calculate taxes, understanding sales tax nexus ensures you know where you must collect tax. Various factors establish nexus, such as having a physical presence, employees, or economic activity in a state.
Physical Nexus
A physical nexus is established when your business has a tangible presence in a state, such as an office, warehouse, or employees, creating a legal obligation to collect and remit sales tax in that state. Consequently, this requires compliance with local sales tax laws.
Economic Nexus
An economic nexus ensures you know where you must collect tax. Various factors establish nexus, such as having a physical presence, employees, or economic activity in a state.Currently, most states, including California, New York, Texas, and Illinois, base their economic nexus solely on sales volume and no longer consider the number of transactions. Now, their economic nexus is typically based solely on sales volume, often $100,000 or $500,000 in annual sales, regardless of physical presence.Always check each state’s current requirements, as thresholds and rules can change.
Tracking exposure inside Shopify
To help sellers monitor their tax obligations, Shopify provides a liability tracker tool that highlights where your business is approaching or has crossed nexus thresholds.This automatically reviews your Shopify sales data, and highlights states where you have either reached or are approaching nexus thresholds, displaying statuses such as:
Monitoring: If you have reached 80% of a state’s threshold.
Action Required: If you have crossed the threshold and must register to collect tax.
By regularly reviewing this tracker, you can proactively identify new tax liabilities, register in the appropriate states, and ensure you remain compliant as your business grows.
Step-by-Step: How To Configure Shopify For Tax Collection
Before you can legally collect sales tax from customers, you must register for sales tax permit with each state where you have established nexus. Collecting sales tax without a valid permit is prohibited and can result in penalties.The registration process typically involves applying through the state’s Department of Revenue, providing business details, and receiving a permit number. After that, you can begin setting up your Shopify account.
From your Shopify admin, go to Settings > Taxes and duties.
In the Manage sales tax collection section, click your country or region.
Click Collect sales tax.
In the Tax number, enter your tax number. If you have applied for a tax number, but don’t have one yet, then leave this field blank. You can update it when you receive your number.
Click Collect tax.
Optional: To add more regions and account numbers, click Collect sales tax.
Managing Overrides and Exemptions
Overrides are where brands either get very precise or very confused. Common override needs include tax-exempt products, reduced rates, and differences in shipping taxability by state.For B2B sales and exemption claims, Shopify Tax now offers an integrated exemption feature. Sellers can now upload and manage exemption certificates directly within the customer profile in the Shopify admin, streamlining compliance and recordkeeping.While Shopify can improve the transaction experience, maintaining accurate exemption records in the platform is essential for audit defense.
Setting Up International Taxes
If you sell to customers outside the United States, you may need to collect and remit international taxes such as VAT (Value Added Tax).Shopify provides tools to help you configure these taxes for different countries, ensuring you meet global tax obligations. Be sure to research the requirements for each country you sell to, as international tax laws can vary widely.
Shopify Collection vs. Remittance
A common misconception among Shopify merchants is that Shopify handles the entire sales tax process, including sending the collected tax to the state.In reality, Shopify only calculates and collects the tax at checkout, then deposits those funds (along with your order proceeds) into your bank account. The responsibility for filing sales tax returns and remitting payment to the state remains entirely with you, the merchant.A simple flow looks like this:However, the gap between collection and remittance is bridged with the Shopify Tax Automatic Filing feature. For eligible U.S. states, Shopify can now facilitate the remittance process, effectively taking the funds and filing the returns for you.
Shop Channel Orders: Limited Remittance Scope
Currently, Shopify automatically collects and remits sales tax for all U.S. orders placed within the Shop app marketplace. However, this automatic remittance does not apply to Shop Pay checkouts on your own website, but only orders made directly through the Shop App are covered.If you sell across multiple channels, be sure to document which channel is responsible for remitting tax and reconcile accordingly.
Shopify Tax: Is It Worth It?
Shopify Tax is designed to minimize manual work and reduce the risk of costly errors, especially as your business grows and tax complexity increases. Key features that set Shopify Tax apart include:
Smart Tax Categorization: Automatically applies the correct tax rates to different product categories, such as clothing, digital goods, or other items, helping you avoid misclassification and compliance issues.
Address Validation: Calculates sales tax based on precise rooftop locations rather than just zip codes, ensuring more accurate rates and reducing the risk of under- or over-collection in states with complex local tax rules.
Enhanced Reporting: Offers improved reporting tools that make it easier to export detailed tax reports for reconciliation and tax season, streamlining your accounting workflow.
Shopify Tax is free for the first $100,000 in annual sales, then charges a small per-order fee (0.35% for most plans and 0.25% for Plus, up to $.99 per order), with no separate subscription required.If your store operates in a limited number of states with a simple product catalog, Shopify’s basic tax calculation may be sufficient. However, if you’re expanding into new states, adding more SKUs, or want to automate compliance and reduce manual oversight, Shopify Tax’s advanced features can provide significant value and peace of mind.
Common Pitfalls Sellers Should Avoid
Most sales tax issues do not come from “Shopify calculated the wrong rate.” They come from process gaps around registration timing, product taxability, and filing discipline.A few recurring pitfalls are:
Collecting without a permit: Turning on collection before registration can create problems with the state.
Marketplace confusion: Amazon may remit on marketplace orders; your Shopify storefront generally does not.
State nexus assumptions: a state you did not owe last year may become a requirement after a few months of growth.
Product miscoding: taxability varies for apparel, groceries, supplements, and digital items.
Missed filings: Many states require a return even when you had no sales during the period.
These are also the pitfalls that create compounding pain: once you are late in multiple states, cleanup takes time, documents need to be prepared, and careful amendments are required.
Frequently Asked Questions
1. Does Shopify automatically add sales tax?+
Shopify does not automatically handle everything related to sales tax.
It can calculate and add sales tax at checkout, but only after setup
You must register for a sales tax permit in each state where you have nexus
Registration must happen before enabling Shopify’s tax calculations
You’re also responsible for tracking nexus thresholds, including across marketplaces
In short, Shopify can apply sales tax—but only after you’ve completed the required registrations and setup.
2. Does Shopify collect and pay taxes?+
Shopify does not automatically collect, file, or remit sales taxes on your behalf by default. As the store owner, you remain responsible for setting up tax collection, filing returns, and paying any taxes owed to the appropriate authorities.
However, if you enable Shopify Tax and configure automated filing, Shopify can help calculate, collect, and in some cases file and remit taxes for you. This feature streamlines the process, but you still need to ensure everything is properly set up and compliant with local tax laws.
3. How is tax calculated in Shopify?+
Shopify calculates sales tax based on the customer’s shipping address, applicable state and local tax rates, your business’s physical or economic nexus, and the products being sold. It then applies the correct tax rate and rounds the tax at the line-item level.
4. Why is Shopify not collecting sales tax?+
Shopify may not collect sales tax if tax collection isn’t enabled in your settings, products are marked as non-taxable, or you haven’t established a sales tax nexus in the customer’s state.
5. How much tax do you pay on Shopify?+
The amount of tax you pay on Shopify depends on your location and plan, but Shopify may also charge a small fee for using its tax calculation feature. In the United States, this fee is typically 0.35% per order, or 0.25% if you’re on the Shopify Plus plan, with a maximum charge of $0.99 USD per order. In the United Kingdom and the European Union, the fee is slightly lower at 0.25%, or 0.15% for Shopify Plus users, also capped at $0.99 USD per order.

Sales tax is often the most talked about tax for US remote sellers. However, there are several other taxes that sellers may need clarification on. Tax compliance around remote sellers involves other taxes, such as use, excise, and value-added (VAT) taxes. People often face difficulty differentiating them and consider them as the same thing. If you are one of them, this blog is for you. It discusses the difference between sales tax and other types of taxes.
What is Sales Tax?
A sales tax is a consumption tax assessed on the sale of taxable goods or service. It is usually added to the selling price of an item, so the seller collects it when a customer makes a taxable purchase. The customer pays sales tax in addition to the cost of the purchased product or service to the seller, who collects and remits it to the US federal government. The seller is responsible for sales tax collection, remittance, filing, and reporting. As a seller, you must have an economic or physical nexusto become eligible to collect and remit sales tax to the state. Each state has its regulations and rates for sales tax. Glimpse and learn about various sales tax facts in each state in our earlier blog. Lastly, some key points to remember about sales tax are:
Sales tax is imposed on tangible personal property, including furniture, toys, clothing, and other goods.
It is collected at the point of sale from the buyer.
The sales tax rate is usually calculated as a percentage of the transaction price.
If the seller fails to collect the due sales tax, they must pay it out of their pockets.
What is Use Tax?
Use tax is the tax on the use, consumption, or storage of taxable products and services. It is imposed on items where no sales tax has been paid earlier. If the sales tax is imposed on some products or services, use tax does not apply to such items.Use tax serves as a way to ensure that buyers who purchase items from online or out-of-state sales, where sales tax was not collected, still contribute to tax collection. Use tax is also called consumer use tax, as the buyer or consumer pays sales tax. Consumers directly pay use tax to the state’s Department of Revenue and file separate use tax returns.
Example of Use Tax
If your business is based in any state that charges sales tax, such as Florida, and sells to local customers there, you must collect and remit sales tax. If a buyer purchases a taxable item from some state that does not impose a sales tax and uses it in another state, they must pay use tax as a consumer if they don’t plan on reselling the item.
Key Differences between Sales Tax vs. Use Tax
Use tax and sales tax are often considered the same, but the two have some differences. Here are some of the critical differences between use tax and sales tax.
Use tax rates can be different from sales tax rates. It is complementary to sales tax.
It is only applicable on the purchase of taxable products where no sales tax was paid at the time of purchasing.
It may apply to items exempt from sales tax.
In consumer use tax, the purchaser is responsible for remitting the tax to their respective taxing jurisdiction.
What is Excise Tax?
The government imposes an excise tax to generate revenue that could be used to fund state programs. Excise tax refers to the tax imposed on specific items, mainly luxury goods or non-essential activities. The tax is usually included in the price of the taxable product or service. Understanding excise tax implementation is relatively simple. It entails that all businesses pay excise tax on certain goods and services. However, goods used for a specific purpose, for instance, alcohol used in medicines, might be tax-exempt.
Example of Excise Tax
Excise tax is usually imposed on fuel, alcohol, tobacco, airline tickets, and wagering. If a buyer visits a gas station to fill up their vehicle, a portion of the price includes excise tax. The seller collects and pays this tax to the government. In contrast, sales tax is imposed on a wide range of tangible goods, including furniture, toys, packaged food, and clothing.
Key Differences between Sales Tax vs. Excise Tax
Here are some critical differences between excise tax and sales tax.
Excise tax only applies to specific goods and services.
Excise tax is determined based on the volume of the taxable goods sold.
The calculation for excise tax can be more complex than sales tax.
Some excise taxes are known as sin taxes because they discourage certain activities harmful to society (such as cigarette production).
What is Sales Tax vs. Value-Added Tax?
Value Added Tax, commonly known as VAT, is a consumption tax on goods and services imposed throughout all phases of the supply chain where value is added: from sourcing, manufacturing, packaging, and order fulfillment until the point of sale VAT is imposed.Around 170 countries impose a value-added tax, but the US is an exemption. The United States does not have VAT; we impose excise, sales, and use taxes.
Why Different Types of Taxes Exist
Many people assume that all consumption taxes serve the same purpose. In reality, governments use different tax structures to address different economic activities and policy goals. Sales tax, use tax, excise tax, and value-added tax were designed to apply at different stages of the economic cycle. While they all generate government revenue, they operate differently depending on when a transaction occurs and who is responsible for paying the tax. Several reasons explain why these separate tax systems exist:
Different points of taxation: Some taxes apply at the retail stage when a product is sold to the final customer. Others may apply earlier in the supply chain, such as during manufacturing or distribution. Governments use different systems depending on when they want the tax to be collected.
Different policy goals: Certain taxes are created not only to generate revenue but also to influence behavior. For example, excise taxes on tobacco or alcohol are sometimes used to discourage excessive consumption of products that may affect public health.
Different economic structures across countries: Some rely heavily on value-added taxes, while others prefer retail-based sales taxes. These differences reflect how governments structure their tax systems and administrative processes.
Understanding why these tax systems exist makes it easier to recognize how they interact in real-world business transactions.
Why Use Tax Exist in the United States
Use tax exists primarily to prevent businesses and consumers from avoiding sales tax by purchasing products from out-of-state sellers. Without use tax, buyers could avoid paying tax simply by purchasing goods in jurisdictions where sales tax was not collected. Use tax works as a complement to sales tax, ensuring that taxable purchases remain subject to tax even when the seller did not collect it during the transaction. Here are several situations where use tax may apply:
Online purchases without collected sales tax: If a buyer purchases taxable goods from an out-of-state seller that does not collect sales tax, the buyer may still owe use tax to their home state.
Business purchases for internal use: Businesses sometimes purchase equipment, supplies, or software from vendors that do not charge sales tax. If the items are used within the state, the business may be responsible for reporting and paying use tax.
fInventory withdrawn for internal use: When a business removes inventory originally purchased for resale and uses it internally, that item may become subject to use tax because it is no longer being resold.
Because of these scenarios, many states require both businesses and consumers to report unpaid use tax on tax filings.
How VAT Works in Countries That Use It
Value-added tax operates very differently from the retail sales tax system used in the United States. Instead of collecting tax only at the final retail sale, VAT is applied incrementally at multiple stages of production and distribution. Each participant in the supply chain charges VAT on their sales but can also deduct the VAT paid on business purchases. This process allows tax to be applied only to the value added at each stage of production. A simplified example illustrates how the system works:
Manufacturer stage: A manufacturer sells goods to a wholesaler and charges VAT on the sale. The manufacturer remits the collected VAT to the tax authority.
Distribution stage: The wholesaler sells the product to a retailer and also charges VAT. However, the wholesaler can deduct the VAT paid to the manufacturer from the VAT collected from the retailer.
Retail stage: The retailer sells the final product to the consumer and charges VAT on the full retail price. The consumer ultimately bears the cost of the tax.
Because VAT is collected in stages, governments can track transactions throughout the supply chain rather than relying solely on the final retail sale.
Why Businesses Must Understand These Tax Differences
For businesses selling products domestically or internationally, understanding the difference between these tax systems is essential for maintaining compliance and avoiding unexpected tax liabilities. Different taxes can apply depending on the type of product being sold, the location of the buyer, and the structure of the transaction. Here are several practical reasons businesses should understand these distinctions.
Preventing compliance mistakes: Confusing sales tax and use tax responsibilities can lead to underreported tax liabilities. Businesses that do not properly track these obligations may face penalties or audit risks.
Managing cross-border sales: Companies selling internationally may encounter VAT systems in other countries, even though the United States primarily relies on sales tax and excise tax. Understanding the difference helps businesses prepare for international expansion.
Improving financial planning: Taxes can significantly affect pricing, margins, and reporting obligations. Businesses that understand how these taxes operate can make more informed decisions about sourcing products and expanding into new markets.
Learning the differences between these tax systems allows businesses to operate more confidently in complex tax environments.

Drop shipping has become a hot trend in ecommerce, allowing sellers to run their businesses without stocking inventory. While this model reduces upfront costs and lets you focus on sales and customer service, it also comes with its own challenges—especially around sales taxes. Are you wondering how sales tax works in the world of drop shipping? This ultimate guide is here to help. We’ll break down the basics and give you the tools to handle your sales tax responsibilities like a pro.
What is Drop Shipping?
Drop shipping is an ecommerce model where an online store sells products to consumers without keeping them in stock. Instead, when a store sells a product, it purchases the item from a third-party vendor, who then ships it directly to the customer. In essence, the seller never sees or handles the product. Imagine this: You’re the retailer, but instead of having a warehouse stacked with products, your role is more of an intermediary. When a customer orders on your website, you forward the details to a third-party supplier, who then handles packing and shipping the product directly to the customer’s doorstep. Pretty neat, huh?This fantastic setup means you don’t have to deal with the nitty-gritty of inventory management or shipping logistics. It’s like being a curator for an art gallery; you select what goes on display and how to present it, while someone else handles the behind-the-scenes details.
The New Standard: Economic Nexus
While physical presence used to be the only way to trigger tax obligations, the 2018 Supreme Court changed everything. Today, most dropshippers trigger economic nexus once they cross a state’s financial threshold, most commonly:
$100,000 in gross sales, or
200 separate transactions in a calendar year
Note: Some states have gross sales thresholds greater than $100,000, such as Alabama ($250,000) and New York ($500,000).In addition,as of Jan 1, 2026, many states (e.g., Illinois, Indiana, Iowa, and Maine) have removed the 200-transaction threshold.Crossing these thresholds means you must register and collect sales tax in that state.For more information about each state’s economic nexus, check out here: Economic Nexus: Everything You Need to Know.
The Three Points of View of Drop Shipping
The Customer
From the customer’s viewpoint, it’s business as usual—just like any other online shopping experience. They scroll through the online catalog, pick out what they like, and pay the retailer, including any relevant taxes. Then they simply wait for their package to arrive, hopefully within the estimated delivery window.
The Seller
When an order and payment come in from a customer, the seller springs into action. For any products not sitting in a warehouse—because we’re talking drop shipping here—the seller quickly places an order with their trusty supplier. Along with the payment, the seller shares the customer’s shipping details with the supplier to ensure the package reaches the correct destination.
The Supplier
Once the supplier receives the order and payment from the seller, it’s their turn to act. They locate the ordered items within their inventory, neatly package them, and then ship them to the customer’s doorstep. It’s a streamlined process that cuts out the middleman for shipping, making the whole transaction as efficient as possible.
Who Should Pay Sales Taxes in Drop Shipping?
Determining who is responsible for collecting and remitting sales tax in a drop-ship scenario can be complex. Sales tax is regulated at the state level, and each state has its own rules. Generally, the seller (the retailer) should collect sales tax from the customer and then remit it to the appropriate tax jurisdiction.However, in drop shipping, since the product goes directly from the supplier to the customer, three potential parties are involved: the customer, the seller, and the supplier.
If the seller (retailer) has a business presence (sales tax nexus) in the same state as the customer, then the seller is responsible for collecting and remitting sales tax.
If the seller (retailer) doesn’t have nexus in the customer’s state, but the supplier does, the supplier may be required to collect and remit sales tax in the customer’s state (this is particularly common in California; see the ‘10% Markup’ section below).
If neither the seller (retailer) nor the supplier has nexus in the customer’s state, generally, no sales tax needs to be collected and remitted.
Marketplace Facilitator Laws: Is the Tax Already Paid?
If you drop ship through platforms like Amazon, eBay, Etsy, or Walmart Marketplace, your tax burden is significantly lower. Under Marketplace Facilitator Laws active in 45+ states, the platform is responsible for calculating, collecting, and remitting sales tax on your behalf.Note: You may still be required to register for a sales tax permit in states where you have nexus, even if the marketplace handles the money, to report your “exempt” marketplace sales.
Sales Tax Exemption Certificates in Drop Shipping
Sales tax exemption certificates can make the already complex world of drop shipping even trickier. Here’s the deal: when a retailer buys items for resale, they can often avoid paying sales tax by providing a resale certificateto their supplier. It’s important for both parties, the retailer and the supplier, to be well-versed in the rules governing these certificates in the states where they operate.
Tennessee accepts out-of-state certificates for standard resale. However, they are notoriously strict about dropshipping. If a supplier ships to a TN customer on behalf of an unregistered retailer, the supplier often must charge tax.
Maryland has recently updated its guidance to allow more flexibility for registered out-of-state retailers, provided the goods are strictly for resale.
Some states, such as Hawaii, Illinois, and Massachusetts, do not accept out-of-state resale certificates for drop shipments. If your customer is in one of these states and you aren’t registered there, your supplier may be forced to charge you sales tax.
Mishandling the documentation of a tax-exempt sale may result in fines or other headaches. Therefore, it’s crucial to maintain accurate records to prevent potential issues down the road.
Dropshipping in California: The 10% Markup Rule
California is the most complex state for dropshippers. If your supplier is in California (or has a warehouse there) and ships to a CA customer on your behalf, and you are not registered for a CA permit, the supplier is liable for the tax.To protect themselves, the California Department of Tax and Fee Administration (CDTFA) requires the supplier to tax the actual retail price if known. The 10% markup is a default safety net when the retailer refuses to share their margins.
Preparing for Sales Tax Compliance
Here are some steps to help you prepare for sales tax compliance:
Identify Nexus: First, determine where you must pay sales tax and which states your business has a presence in. This might include states where you have physical locations, employees, or even a high sales volume.
Calculate and Collect Sales Tax: Use automated tools or consult with tax professionals to ensure you charge the correct rate.
File and Remit Sales Tax: Depending on your sales volume, you’ll need to file and remit sales tax on a monthly, quarterly, semi-annually, or annual basis.
Document Exemption Certificates: If you’re using resale certificates, keep accurate records showing compliance with the law.
Frequently Asked Questions
1. What permits do you need for dropshipping?+
For dropshipping, you’ll generally need the same permits and registrations required for most businesses. This typically includes obtaining a business license or local permit, depending on your city or state requirements. You’ll also need to register your business with the appropriate state or local agencies.
In addition, most dropshippers must apply for a federal tax ID number (EIN), register with their state’s tax authority, secure a sales tax permit to collect and remit sales tax where required, and comply with state rules on unemployment insurance and workers’ compensation if they have employees.
2. Do I need to pay taxes if I sell on Spotify?+
Yes. If you sell on Shopify, you’re generally responsible for handling your own tax compliance. As the merchant of record, you must register for the required sales tax permits, file returns, and remit any sales tax you collect to the appropriate state authorities.
Shopify Tax now offers an automated filing feature in eligible U.S. states. However, you’re still responsible for ensuring your registrations and overall compliance are properly set up.

What is Sales Tax?
Sales tax is a consumption tax the government imposes on retail or online sales. Every business, including ecommerce retailers, is responsible for collecting and remitting sales tax to the government. State or local governments can impose a sales tax in their respective jurisdictions, and businesses must comply with the relevant requirements. The definition of taxable items and sales tax rates vary among states, so you must understand them before beginning your business.
Importance of Sales Tax
Sales tax is an important component of government revenue. Usually, people are reluctant to pay income or wealth taxes and try to hide their finances. At the same time, they pay sales tax indirectly and find it comparatively more straightforward than other types of taxes. The sales tax collected from the consumers is used for the betterment of the citizens. States with well-managed tax collection systems grow their economy exponentially. For instance, Florida’s robust sales tax collection system generates steady economic growth.
What do Sales Taxes Pay for?
Most states imply a variety of taxes besides sales tax, such as income tax, use tax, wealth tax, and others. Governments usually collect the revenue from all taxes and use it collectively to finance different projects. It serves as the backbone of state and local government budgets.Here is how states usually spend sales tax.
The General Fund
Many states create a general fund, pooling the funds collected through sales tax and other taxes. A significant amount of sales tax goes into the general fund. The government uses this fund to finance various developmental projects in the state. Every state has a different plan for the allocation of the general fund. Usually, they spend this fund on the following:
Infrastructure improvement: Infrastructure improvement includes projects related to building and repairing roads, transit systems, water pipes, waste facilities, and others. It results in ease of transit and mobility for the people.
Betterment of transportation facilities: Public transport makes life easier for people. The general fund is spent on enhancing transportation facilities and their affordability for the general public.
Recreational facilities: The government can spend general funds on improving recreational facilities such as public parks. As a result, people can strengthen their community relations.
Fire department development: The fire department plays a significant role in protecting the lives and properties of people through firefighting. The tax is spent on getting the latest equipment, providing training, and improving the services of this department.
Police department development: The police department aims to provide a safe and secure environment to the public. The government uses the sales tax revenue to develop the police department to provide better public security services.
Public schools: Education is one of the most important concerns of governments, and they use tax revenue to improve public education facilities. The development of new schools and the improvement of existing schools are the focus of the general fund.
Provision of healthcare facilities: Local and state governments ensure that the citizens get the best healthcare facilities when needed. They use tax revenue to improve emergency healthcare and other medical care projects. It includes the provision of free or subsidized healthcare facilities and health insurance.
Sustainability projects: Another vital area is environmental safety. The government spends the general fund on projects that promote environmental sustainability. They may run awareness campaigns, conduct training programs and seminars, or provide alternative products that create environmental carbon footprints.
Besides these projects, the government may spend the sales tax on other activities promoting individuals’ social and economic security. Mass awareness programs, training facilities, seminars, and workshops are also a part of government expenditures.Some states allocate a significant portion of the general fund for healthcare facilities while others for educational facilities. The difference in allocation depends on the specific needs of the states.
Special Allocations
Sometimes, the government may decide to spend the sales tax on projects other than the general allocations. In such a situation, they pass a bill through the legislature to allocate the sales tax for a specific project. This may result in local and state governments temporarily increasing the sales tax rate to finance special projects. Some states have a separate fund allocated for special projects. They keep a specific percentage of the collected sales tax in that fund and use it when needed. The remaining portion of the sales tax revenue goes to the general fund.
How Sales Tax Spending Decisions Are Made
Sales tax revenue does not go directly into one fixed program. Instead, state and local governments decide how funds are distributed through a budgeting process that evaluates economic conditions, population needs, and long-term priorities. These decisions often happen months before the fiscal year begins and may change depending on revenue projections. Several elements influence how spending decisions take shape:
Legislative budgeting: Lawmakers review expected tax revenue and determine how much funding different departments receive each year.
Economic forecasts: If consumer spending rises or falls, governments may adjust their funding strategies to maintain stability.
Public priorities: Some regions allocate more toward safety programs, while others focus on transportation or education, depending on local needs.
Because each state follows its own process, the same level of sales tax revenue can produce very different outcomes across the country.
How Sales Tax Supports Everyday Community Services
When people think about sales tax spending, they often picture large infrastructure projects. However, many smaller services rely on this revenue to operate consistently. These daily improvements may not always be visible, yet they contribute to how communities function over time. Examples of everyday impact include:
Public space upkeep: Maintenance of parks, sidewalks, and shared facilities helps communities remain accessible and safe.
Local programs: Cities may fund training sessions, public workshops, or neighborhood initiatives that support residents.
Routine safety improvements: Small upgrades such as signage, lighting, or emergency preparedness programs often come from local budgets supported by sales tax.
These smaller services demonstrate how tax revenue influences daily life beyond major construction or development projects.
Why Sales Tax Spending Looks Different in Every State
Not all states allocate sales tax revenue in the same way. Differences in population size, industry focus, and economic activity shape how funds are distributed once they enter a state’s budget. For example, a tourism-focused state may invest more heavily in transportation networks, while a rapidly growing region might prioritize expanding schools or public safety programs. Geographic and economic differences also play a role, as rural areas may focus on maintaining essential services rather than launching large projects. Key factors that influence spending differences include:
Population growth and urban development
Regional industries such as tourism or manufacturing
Legislative decisions tied to local priorities
Recognizing these variations helps explain why two states with similar sales tax rates may still invest in very different areas.
The Indirect Benefits Sales Tax Spending Can Have on Businesses
Sales tax is often discussed from a consumer perspective, but businesses may also benefit indirectly when revenue is used to improve local infrastructure and services. These benefits do not always appear immediately, yet they can influence long-term growth and customer activity. Some ways businesses may feel these effects include:
Improved accessibility: Better roads, transit routes, and public spaces can increase customer traffic and make it easier for employees to commute.
Safer business environments: Investments in emergency services and community safety initiatives can create more stable operating conditions.
Economic development projects: Revitalized public areas or upgraded facilities may attract more visitors, which can support nearby retailers and service providers.
While sales tax spending is not directed toward individual businesses, the improvements funded through public budgets can help strengthen the overall business environment.

Get Complexity out of Sales Tax Compliance
Besides managing a full-fledged business, sales tax collection and remittance can get complicated, but automation can help. Connect with TaxHero by booking a call and learn how we can streamline your sales tax compliance. Thanks to globalization and the World Wide Web, businesses can now sell their products across the United States and worldwide, leading to opportunities for growth. However, complying with various rules and regulations can be challenging. Fortunately, the Streamlined Sales Tax Program (SSTP) offers a solution.Sales tax can be a complicated matter due to constantly evolving rules and requirements regarding its collection and remittance. To ensure businesses can properly understand and comply with these regulations, seeking professional assistance is often the best course of action.The SSTP is an initiative by the state and local governments to reduce the complexity of tax collection for retailers. This article provides everything you need to know about Streamlined Sales Tax.
What is Streamlined Sales Tax?
Streamlined Sales Tax (SST) is a program designed and run by states to simplify sales and use tax compliance for retailers by developing an organized sales and use tax system. It was formed in 1999 – 2000 to streamlinesales tax compliance with retailers responsible for collecting and remitting sales tax. The Streamlined Sales Tax Project (SSTP) is a collective national effort of the states to modernize the collection and remittance system of sales and use tax. States that become program members enter the Streamlined Sales and Use Tax Agreement (SSUTA). It requires them to comply with the policies and take measures to achieve the objectives of this initiative. The project benefits brick-and-mortar and ecommerce sellers alike. You can talk to a sales tax expert at TaxHero to determine if you qualify for SST or need registration.
The Objectives of the SSTP
The following are the main objectives of the Streamlined Sales Tax Program.
To minimize administrative costs and responsibility for the retailers.
To modernize the sales and use tax collection system.
To offer a fair, competitive environment to remote sellers and brick-and-mortar stores.
To develop a simple and business-friendly tax collection system
How Does the Streamlined Sales Tax Project Work?
Besides modernizing the sales tax collection system and simplifying it for businesses, the SSTP aims to provide a comprehensive plan to the states to streamline sales taxcollection. This program simplifies tax administration by offering state-level tax collection administration. In addition, it provides uniformity in tax base definitions and state and local sales tax bases. Under this program, all member states have a central electronic registration system. It establishes uniform sales tax collection standards and provides the latest technology systems to facilitate the whole process. All these measures encourage more businesses to register and collect sales tax promptly. It benefits both the government and businesses.
How does SSTP Benefit Businesses?
As discussed earlier, the primary aim of the SSTP is to reduce the complexities of sales tax collection to encourage businesses to collect and remit sales tax to the concerned authorities voluntarily. Small businesses can maximize this program to get worthwhile tax collection incentives. The following are the compelling benefits of SST registration.
If you conduct business in multiple states, you only need to register once, which applies to all SSTP member states. The registration process is simple and quick and occurs through the Streamlined Sales Tax Registration System.
There is no need to update information separately in each state. One update applies to all states.
You can use the same filing forms and exemption certificates for all streamlined sales tax states.
Tracking one identification number is enough for tax payment and filing in all member states.
You can reduce the burden of sales tax collection and filing by using certified sales tax administration software.
You can benefit from the uniform sourcing rules across all member SST states.
Volunteer sellers get free access to sales tax calculation and reporting services from a Certified Service Provider.
Businesses can save their cost by collecting, filing, reporting, and paying sales tax for all jurisdictions at one location.
What are Streamlined Sales Tax States?
The Streamlined Sales Tax Project currently has 23 full member states and one associate member state. Let’s call them the Streamlined Sales Tax States. The list exempts the states with no sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon. The full member states change their sales tax laws according to Streamlined Sales and Use Tax agreement requirements. On the other hand, the associate member states do not change their laws but comply with SSUTA requirements. The following states have full SSTP membership.
Arkansas
Georgia
Indiana
Iowa
Kansas
Kentucky
Michigan
Minnesota
Nebraska
Nevada
New Jersey
North Carolina
North Dakota
Ohio
Oklahoma
Rhode Island
South Dakota
Utah
Vermont
Washington
West Virginia
Wisconsin
Wyoming
Tennessee is an associate member of the project.
Conditions to Qualify in SSTP
You need a sales tax permit or license to collect and remit sales tax in a state where you have your economic or physical nexus. If you have nexus in any of the SSUTA member states, you can benefit from the streamlined sales tax program by registering as a volunteer seller. You must meet the following conditions to qualify and register as a volunteer seller in the Streamlined Sales Tax Program. These conditions must be fulfilled over 12 months.
You must not have a fixed place of business for more than a month in a member state.
The value of your property in the member state must be less than $50,000.
Your payroll in the member state must be less than $50,000.
Your total property or payroll in the member state must not exceed 25%.
Besides these, there might be some additional conditions that you must check before registering.
Why the Streamlined Sales Tax Program Exists
Before the Streamlined Sales Tax Program existed, multi-state selling often meant dealing with sales tax rules that were structured differently from one state to the next. Even when two states taxed the same type of transaction, the steps for registration, product definitions, and reporting requirements could be inconsistent, which created avoidable work for businesses expanding across state lines. To understand the “why” behind SST, it helps to focus on the problem it was built to solve: reducing compliance burden without taking away state authority. The Streamlined Sales and Use Tax Agreement (SSUTA) describes this as simplifying and modernizing sales and use tax administration to substantially reduce compliance burden. (This is the core “purpose statement” that supports the section.) What the program was designed to improve (in practical terms):
More consistent administration, not “one national tax”: SST is designed to standardize the way certain tax rules are administered across participating states, so sellers do not have to relearn an entirely different system every time they expand.
A central path for multi-state registration: Instead of approaching every state separately with different registration experiences, SST supports a centralized registration approach for participating states.
Modernized rules that support ecommerce reality: The SSUTA framework includes sourcing and administrative standards that support remote selling, rather than treating interstate sales as a special case that requires totally different logic every time.
What Streamlined Sales Tax Does Not Change
SST helps standardize parts of the process, but it does not remove the core obligations businesses still have under state law. This section is important for SEO because it matches what searchers are often really asking: “Does this program make sales tax go away?” The answer is no, and this clarifies exactly what remains unchanged. What SST does NOT do (quick clarity list):
It does not create a nationwide tax system: Member states still control their own sales tax systems and remain responsible for their own laws and enforcement. The SSUTA is an agreement to improve administration, not a replacement for state authority.
It does not erase nexus considerations: Whether you need to collect tax in a state still depends on your activity and obligations under that state’s rules. SST does not decide that for you. (It helps with the process once you’re registered/participating.)
It does not make local tax “disappear”: Participating states may streamline administration, but local taxes can still exist, and businesses still need accurate rate calculation and correct reporting.
How SST Helps Remote Sellers Navigate Multi-State Sales
Remote sellers usually struggle with sales tax for a simple reason: once you sell into multiple states, compliance becomes a systems problem. SST supports remote sellers by offering structured paths that reduce repetitive setup work and can support automation through certified providers. Instead of repeating “benefits” you already listed earlier, this section adds how the workflow actually becomes easier. Where SST can reduce friction for remote sellers:
Central registration reduces repeated onboarding: Remote sellers can register for participating states through the Streamlined system rather than starting from scratch every time.
Certified Service Providers support calculation + reporting workflows: SST has a Certified Service Provider (CSP) program, which is specifically designed to support sellers with the mechanics of compliance.
Volunteer sellers may qualify for free CSP services (in certain cases): SST outlines criteria for when sellers can receive free CSP services in a state, tied to registering through the Streamlined system and meeting eligibility conditions.
Their SST Eligibility
Many sellers wait until sales tax becomes painful before reviewing SST eligibility. A more practical approach is to evaluate sooner, when operational complexity starts showing up in predictable ways. This section is designed to capture search intent like “Do I qualify?” and “When should I use SST?” without repeating your qualification rules. Signals it may be time to review SST eligibility:
You are adding new states faster than your admin process can handle: If each new state expansion creates a new manual setup and internal checklist, SST may help reduce repeated work through its centralized approach.
You are relying on manual tax rate updates or inconsistent tools: If your team is updating rates, mappings, or reporting logic manually, it’s often a sign you’ve outgrown a DIY approach and should evaluate a structured compliance workflow. (SST’s CSP model exists for this reason.)
You want to know whether “volunteer seller” status applies to you: The SST free services program is tied to specific criteria and registration steps, so sellers who may qualify typically benefit from reviewing this early, not after problems occur.

Selling online means navigating sales tax rules that differ in nearly every state. Below are clear answers to the Frequently Asked Questions (FAQs) ecommerce and CPG brands ask most, from nexus to registration to back taxes.
Do small businesses need to collect sales tax? It depends. If your business sells taxable goods or services and has sales tax nexus in a state, you generally must register, collect sales tax when required, and file returns there.
Nexus can come from a physical presence or from crossing a state’s economic threshold, and the rules differ in every sales-tax state. The sections below break down how it all works so that each one can stand on its own.
As your business grows, you’ll commonly encounter 2 terms: business registration and sales tax registration. They sound similar, but they serve entirely different purposes.
Registering your LLC or getting a local business license doesn’t mean you’re allowed to collect sales tax. On the other hand, getting a sales tax permit doesn’t grant you the legal right to operate a physical business entity in that state.
Mixing up these two distinct requirements exposes your ecommerce brand to noncompliance risks. This guide clarifies the difference and explains the factors you need to consider before registering.
You only need to register for a sales tax permit once your business establishes a sales tax nexus in a specific state. Sales tax nexus is a legal term for a business connection to a jurisdiction that is significant enough to trigger tax obligations.
For ecommerce brands, nexus generally comes down to two types:
For scaling ecommerce brands that are required to register in multiple states or are close to crossing a nexus threshold, outsourcing compliance can help your business save time and resources.
A full-service provider generally handles 4 key compliance needs.
TaxHero doesn’t just sell you a software subscription and leave your team to manage it. We act as your fully outsourced sales tax department, taking the entire administrative burden off your plate so you can focus strictly on scaling your brand.
Our team combines automated multi-channel sales data with dedicated sales tax experts to handle your compliance lifecycle from start to finish:
Sales tax compliance becomes more complicated as an ecommerce business expands into multiple states. Each state has its own tax rules, registration requirements, filing frequencies, and deadlines.
The easiest way to manage multistate sales tax is to use a sales tax automation solution that integrates with your sales channels, calculates applicable taxes, and helps you prepare and file returns. A managed service can reduce manual work further by combining technology with professional support.
However, automation alone doesn’t guarantee full compliance. Businesses must still identify where they have sales tax nexus, register where required, maintain accurate transaction data, and meet their tax obligations.
This guide explains how sales tax automation works, what to look for in a solution, and how to decide between software and a managed service.
Not every automation tool is built the same way, and the feature list can get long fast. Here’s what actually matters for an ecommerce brand:
A reliable sales tax automation process starts with identifying obligations and ends with confirming that required returns have been filed and payments made.
Cost is where many ecommerce sellers get surprised, mostly because pricing in this space isn’t standardized. A few real numbers to work from:
Online marketplaces have become a major sales channel for ecommerce businesses. If you sell products through platforms such as Amazon, eBay, Etsy, Walmart, or TikTok Shop, those platforms may act as marketplace facilitators.
A marketplace facilitator helps facilitate sales between sellers and customers. Depending on the platform, it may list products, process payments, collect sales tax, and assist with shipping.
Marketplace facilitator laws determine when these platforms must collect and remit sales tax on behalf of sellers. However, using a marketplace does not automatically eliminate a seller’s own sales tax obligations.
Sellers may still need to determine where they have economic nexus, register for sales tax, collect tax on direct sales, file returns, and maintain compliance records.
This guide explains how marketplace facilitator laws work, how they affect sellers, and how marketplace sales can affect economic nexus.
Sales tax can be one of the most confusing parts of running an ecommerce or online business. Rules vary by state, local jurisdiction, product, service, and the customer’s location.
This guide explains what sales tax is, how it works, when you need to collect it, what nexus means, how to register and file, and how to stay compliant across multiple states.
To calculate your tax, you must list the price of your taxable product, including any taxable shipping charges. After that, determine the combined sales tax rate that applies to the transaction’s location. Then convert the state’s combined sales tax rate to decimal form.
Once you convert the rate to decimal format, multiply your product’s price by the decimal. The result is your estimated sales tax for that transaction.
Sales tax nexus is a rule you can’t ignore as an ecommerce business. It’s the legal link between your business and a specific state that requires you to collect sales tax from customers living there. Whether you’re shipping orders from home or selling nationwide, crossing these state lines can change your tax responsibilities overnight.
To secure your business, you must understand what creates a nexus and what to do next. You can cross the line by storing inventory in an out-of-state warehouse or by simply hitting a state’s dollar sales threshold.
As sales tax rules vary across the country, this guide breaks down the complex laws for U.S. ecommerce business owners.
Nexus monitoring is an ongoing operational task for every growing ecommerce business. As your sales volumes fluctuate and state rules constantly shift, a footprint that’s perfectly compliant today could easily cross a legal threshold tomorrow.
A multi-layered tracking strategy is one of the best ways to actively monitor your nexus.
Once a business establishes nexus in a state, it typically becomes responsible for several tax compliance obligations. These responsibilities ensure that the business collects and reports sales tax correctly within that jurisdiction.
Failing to respond promptly after establishing nexus can result in penalties or additional tax liabilities.
After nexus is established, businesses usually need to:
Selling online and growing your business is straightforward until you deal with U.S. sales tax. Instead of focusing on daily business, you now have to worry about compliance every time you sell to customers in different states.
The biggest hurdle is economic nexus, a law that requires you to register, collect, and remit sales tax in another state once you hit a specific sales threshold, even if you operate from home.
Managing this on your own is nearly impossible because the nation has more than 11,000 sales tax jurisdictions, each with its own changing rules, rates, and deadlines. As the paperwork piles up, many businesses wonder whether someone else can handle sales tax registration and filing, and whether their ecommerce business needs a dedicated compliance service.
This guide answers those questions by breaking down how sales tax for ecommerce businesses works, what tasks you can hand off or outsource, and how to choose the right sales tax solution.
No, standard ecommerce platforms generally cannot handle your sales tax compliance on their own or without specific configurations. A common mistake new online sellers make is assuming a platform manages their entire tax burden just because it calculates tax at checkout.
To protect your business, you must understand the difference between these 3 options:
Sales tax compliance mistakes can lead to unexpected back taxes, interest charges, and costly audit penalties. Even well-intentioned online brands frequently fall into common traps because state rules are constantly moving.
To keep your business protected, make sure you are avoiding these six critical compliance pitfalls:

However, the gap between collection and remittance is bridged with the Shopify Tax Automatic Filing feature. For eligible U.S. states, Shopify can now facilitate the remittance process, effectively taking the funds and filing the returns for you.
Shopify Tax is free for the first $100,000 in annual sales, then charges a small per-order fee (0.35% for most plans and 0.25% for Plus, up to $.99 per order), with no separate subscription required.
If your store operates in a limited number of states with a simple product catalog, Shopify’s basic tax calculation may be sufficient. However, if you’re expanding into new states, adding more SKUs, or want to automate compliance and reduce manual oversight, Shopify Tax’s advanced features can provide significant value and peace of mind.
Sales tax is often the most talked about tax for US remote sellers. However, there are several other taxes that sellers may need clarification on. Tax compliance around remote sellers involves other taxes, such as use, excise, and value-added (VAT) taxes.
People often face difficulty differentiating them and consider them as the same thing. If you are one of them, this blog is for you. It discusses the difference between sales tax and other types of taxes.
Many people assume that all consumption taxes serve the same purpose. In reality, governments use different tax structures to address different economic activities and policy goals.
Sales tax, use tax, excise tax, and value-added tax were designed to apply at different stages of the economic cycle. While they all generate government revenue, they operate differently depending on when a transaction occurs and who is responsible for paying the tax.
Several reasons explain why these separate tax systems exist:
For businesses selling products domestically or internationally, understanding the difference between these tax systems is essential for maintaining compliance and avoiding unexpected tax liabilities.
Different taxes can apply depending on the type of product being sold, the location of the buyer, and the structure of the transaction.
Here are several practical reasons businesses should understand these distinctions.
Drop shipping has become a hot trend in ecommerce, allowing sellers to run their businesses without stocking inventory. While this model reduces upfront costs and lets you focus on sales and customer service, it also comes with its own challenges—especially around sales taxes.
Are you wondering how sales tax works in the world of drop shipping? This ultimate guide is here to help. We’ll break down the basics and give you the tools to handle your sales tax responsibilities like a pro.
Sales tax is a crucial source of revenue for governments at different levels, and understanding what sales tax pays for is essential to comprehend public services and infrastructure funding. Sales taxes are vital in financing various aspects of society, including education, healthcare, transportation, public safety, and more.
Where does the collected sales tax go? What is sales tax used for? This blog sheds light on how paying sales tax improves communities and provides citizens with necessary resources.
Sales tax revenue does not go directly into one fixed program. Instead, state and local governments decide how funds are distributed through a budgeting process that evaluates economic conditions, population needs, and long-term priorities. These decisions often happen months before the fiscal year begins and may change depending on revenue projections.
