Ultimate Guide to Understanding Economic Nexus

Diving into the ecommerce world is exciting. However, the jargon can be a bit much. One term you’ll hear is “economic nexus.” In simple terms, think of it like a signpost in the world of sales taxes, guiding businesses where they stand.

Here at TaxHero, we want to make things simple. Therefore, we’ll break down this term, explain why it matters, and help you understand how it affects your ecommerce business. Ready to get started?

What is Economic Nexus?

Economic nexus is a set of criteria used to determine whether your ecommerce business has a significant presence in a particular state. This idea became well-known because of the 2018 South Dakota v. Wayfair case. If your ecommerce business meets these criteria, you must follow that state’s tax rules, which means collecting and remitting sales tax.

Simply put, if your ecommerce business has a notable footprint in a state – through sales, transactions, or physical presence – it triggers economic nexus in that jurisdiction.

Thus, the importance of understanding the economic nexus in ecommerce lies in avoiding legal issues and planning finances wisely. In addition, it helps you expand your business smoothly without unexpected tax problems. It serves as a guide for navigating potential tax obligations when entering new markets, ensuring compliance and supporting strategic growth.

Criteria for Establishing Economic Nexus

When establishing an economic nexus for your ecommerce business, states generally consider a few key factors. Here’s what you need to keep an eye on:

Sales Revenue: The total dollar amount of sales. However, states differ in whether they count Gross Sales (everything), while others consider only Taxable Sales (items not exempt).
Transaction Volume: Besides the amount you earn, the number of transactions you conduct in a state also counts. For example, if you have a high volume of sales transactions in a state, it establishes an economic nexus.
Marketplace Sales: In most states, sales made through platforms like Amazon or Walmart do count toward your threshold, even if the marketplace collects the tax for you.
Keeping Up with Changes: State laws regarding economic nexus can change. Make it a practice to regularly check for updates to avoid surprises and ensure you’re meeting all necessary criteria.

State-by-State Variations in Economic Nexus Laws

When managing an ecommerce business that spans different states, it’s vital to be aware of the variations in economic nexus laws across states. Here’s why it matters:

Different Thresholds

First, each state sets its thresholds for establishing economic nexus based on sales revenue or transaction volume. Therefore, it’s essential to be aware of these individual thresholds to remain compliant and avoid unnecessary complications.

As of 2026, here are the updated economic nexus thresholds in each state:

Varied Definitions

Not all states define economic nexus in the same way. Some focus more on sales revenue, while others prioritize transaction volumes or physical presence. Keeping tabs on these variations helps in strategizing your ecommerce business operations effectively.

Seeking Expert Advice

Given the complexities, seeking advice from ecommerce sales tax professionals like TaxHero can be the best action. We can also help you navigate the maze of state laws, ensuring your ecommerce business remains compliant and thrives.

Economic Nexus for Different Business Models

Although economic nexus laws apply broadly, their impact can vary by business model. Therefore, to ensure your business remains compliant, you must understand how your specific industry interacts with nexus laws.

Economic Nexus for SaaS and Software

Software-as-a-Service (SaaS) is taxable in some states (such as New York and Texas) but not in others (such as California).

Nevertheless, even if your service isn’t taxable in a specific state, your gross revenue may still trigger a “non-collecting seller” reporting requirement.

If you are a SaaS provider, your nexus is often triggered purely by your digital footprint.

Economic Nexus for Wholesalers and B2B

In states that use “Gross Sales” as the threshold (like Illinois), your tax-exempt wholesale sales count toward the $100,000 limit. Also, once you hit the limit, you must register and collect valid Exemption Certificates from your customers to avoid being liable for the tax yourself.

The Role of Marketplace Facilitators

If you sell exclusively on Amazon, you may still have economic nexus. While Amazon collects and remits the tax in most states, your sales volume on their platform counts toward your state thresholds.

If you later launch your own direct-to-consumer website, you may already have an immediate obligation to collect tax because of your previous Amazon history.

What to Do if You Fall Below the Threshold?

Recently, several states have updated their laws to remove the “200 transaction” count. As a result, some businesses that previously registered solely on the basis of transaction volume may no longer meet the nexus requirements.

For example, if your business was previously registered in a state like Indiana or Utah solely because of transaction volume (and you don’t hit the $100,000 revenue mark), you may be eligible to de-register.

However, do not simply stop filing. You must follow the state’s formal “account closure” process to avoid “failure to file” penalties.
