How to File Louisiana Sales Tax Online | TaxHero

Filing your Louisiana sales tax return is simple with the state’s online system. You can file and pay directly through the Louisiana Taxpayer Access Point (LaTAP) website, as long as your business is registered to collect and remit sales tax.

This guide will walk you through the step-by-step process of filing online so you can submit returns on time, avoid penalties, and stay compliant with Louisiana’s sales tax rules.

What You Need Before Filing

Before filing your sales tax return, you must prepare specific records to ensure your report is accurate. Here are the standard documents required to file a sales tax return in Louisiana:

  • Louisiana Sales Tax Account (Account ID) – You’re required to provide your Louisiana sales and use tax account ID to file your sales tax return. Once your registration with the Louisiana Department of Revenue (LDR) is approved, you should receive your account details electronically. This is your official state account number.
    NOTE: A “Direct Marketers Permit” is a specific type of sales tax permit for out-of-state sellers who do not have a physical presence in Louisiana and do not meet the economic nexus threshold but voluntarily collect and remit sales tax. It is not the standard sales tax account for all businesses.
  • Louisiana Taxpayer Access Point (LaTAP) Account Log-in Details – The primary way to file your Louisiana sales tax return online is by logging onto your LaTAP account. To access the site, ensure you have your log-in credentials ready (e.g., your username and password).
  • Total Sales – Gather your total revenue during the filing period. This includes all sales, whether they’re taxable or not. Even if you currently have no sales records, you’re still required to file a return.
  • Taxable Sales – Compile the total taxable sales your business made within the filing period. You’ll need this data to determine how much sales tax you owe and must pay for the filing period.
  • Taxable Purchases – Verify the total amount of taxable purchases your business spent within the filing period. This applies to both in-state and out-of-state transactions.
  • Local Sales Tax Report – Louisiana requires businesses to file a local sales tax report as well. The state of Louisiana has a centralized online filing system through LaTAP that allows you to file both state and local sales taxes on one return. This means you must list all your sales in each city, parish, or other local jurisdiction in Louisiana.
  • NAICS Code – You’re required to have your business’s assigned NAICS code available to include on your sales tax return if it’s not already on file. NAICS codes can often be found on your federal corporate income tax return.
  • FEIN Numbers – The LDR requires registered businesses to provide their FEIN numbers. You can enter your FEIN at the bottom of your sales tax return.
  • Bank Account and Routing Number – Select which bank account you want to use for paying the due taxes in your report. Prepare your bank details and routing number ahead of time.
  • Filing Frequency Schedule – The state assigns a specific due date for every registered business based on your sales tax liability during a filing period. You can find your designated filing frequency (monthly, quarterly, or annually) on your official registration documents from the LDR.

Due Dates

In Louisiana, your filing schedule and due dates generally change depending on your monthly collected sales tax. For guidance, refer to the table below.

FREQUENCY LIABILITY REPORTING PERIOD DUE DATE
Monthly Most businesses are initially assigned a monthly filing schedule Monthly 20th day of the month following the reporting period
Quarterly A business may be eligible for quarterly filing if its tax liability averages less than $500 per month.
    • January – March
    • April – June
    • July – September
    • October – December
  • April 20
  • July 20
  • October 20
  • January 20
NOTE: If the 20th day falls on a weekend or a state legal holiday, the due date is moved to the next business day. In the event of a natural disaster, the state applies the same rule.
However, for those who wish to follow an irregular or alternate filing period, you must request approval from the LDR.
Learn more about Louisiana sales tax filing regulations through the Louisiana Administrative Code 61:I.4351.

Due Date Filing Extensions

In case you can’t file or pay your return on time, the LDR does not generally allow a regular filing extension for sales tax. The Louisiana Department of Revenue (LDR) typically only grants extensions in the event of a state-declared disaster and announces them via a Revenue Information Bulletin.
Any interest and penalties will accrue on any payment made after the original due date. The granting of a filing extension does not extend the time to pay the tax due.

Timely Filing Discount

Some states give businesses a discount for collecting, filing, and remitting sales tax on time. In Louisiana, vendors are allowed to deduct and keep a percentage of their sales and use tax as compensation for filing on time.
The vendor’s compensation rate is 1.05%. However, effective for tax periods beginning on or after January 1, 2025, the maximum amount of compensation a vendor can receive is reduced from $1,500 to $750 per month.
The effective rate of the vendor’s compensation is 0.84% due to a change in how the compensation is calculated relative to the new state sales tax rate.
To learn how to compute your vendor’s compensation fee, refer to the latest information from the Louisiana Department of Revenue (LDR).

Filing Amended Returns

If you wish to correct a previously submitted return, you may amend it through LaTAP. Follow the official instructions provided by the Louisiana DOR:
  • Step 1: Log in to your LaTAP account.
  • Step 2: Under the “Account” page, find the “Filing Periods” section.
  • Step 3: Choose the filing period you wish to amend, then click on “View Return.”
  • Step 4: Next, click the “Change” button in the upper-right corner of the return.
  • Step 5: Finally, you can update the information you wish to change or correct. After that, you may now resubmit your return.
NOTE: Even if you previously filed by paper, you can still amend your return through LaTAP.

Refunds

If you refunded a customer and have already filed and paid your sales tax return, Louisiana Rule §4369 allows you to request a sales tax refund.
You may take a credit for the tax on your next sales tax return, or you can file a claim for a refund. To claim your refund, you must file an amended return or a claim for refund form.
In your amended return, you can claim the credit by deducting the refunded amount from the due taxes you originally owed. If you’re filing by paper, ensure you mark the return form as an “Amended” return.
The state typically issues the refund in the same manner as a credit return, which the taxpayer files timely.
Overpayment Refunds: In case you simply had a case of overpayment on your sales tax return, you can file a claim for a refund.
You may fill out the Claim for Refund of Overpayment (Form R-20127), which can be downloaded from the LDR website. After filling out the form, here are more pointers to keep in mind:
  • Retailers often use this refund process for overpayments, and they separate it from a credit taken on a subsequent return.
  • You may refund bad debts. These debts typically refer to uncollectible accounts that you have charged off for federal income tax purposes. You cannot simply deduct bad debts from your sales on your tax return. You must apply for a refund for the tax you paid on the bad debt.
  • The Louisiana Department of Revenue (LDR) will review your claim to determine whether your request is valid or not. Prepare supporting documents to support your refund claim.
NOTE: If your refund claim is $25,000 or higher, the LDR requires you to electronically file all schedules and invoices associated with the refund claim. This rule is in accordance with the Louisiana RS §1520.2.

Filing Zero Returns in Louisiana

The Louisiana Department of Revenue (LDR) requires registered businesses to file a return even if they have no taxes to pay or report. Filing a zero return online is simple. You only have to follow the same steps as filing a standard return.
In the fields asking for your total sales or collected sales tax, you must write zero (0). This lets the LDR know that your return is a zero return.
When filing by paper, the same rule applies.
