How to File Arkansas Sales Tax Online in 2026

Arkansas sales tax is filed online through the Arkansas Taxpayer Access Point (ATAP), the Department of Finance and Administration's portal. The Department's 2026 due date calendar lists the Sales & Use Tax Monthly Report for the previous month on the 20th of each month, and businesses that must make prepayments have two additional payment dates each month. If you had no sales, ATAP lets you file a zero dollar return.

This guide covers who files and when, how to get into ATAP, how to file and amend a return, how Arkansas sources local taxes, how to report no activity, how to pay, and what late filing costs.

This article is educational information, not tax advice. Filing rules, thresholds, and penalties can change, so confirm current requirements with the Arkansas Department of Finance and Administration before you file.

Who has to file, and how often

Businesses registered with the Department to collect sales and use tax report the tax they collect. Arkansas requires out-of-state sellers to collect and remit too. The Department's remote seller page says a remote seller or marketplace facilitator must collect and remit Arkansas sales and use tax if, in the current or previous year, its sales of tangible personal property, taxable services, digital codes, or specified digital products delivered into Arkansas exceeded $100,000 or 200 transactions. The page uses both "200 taxable transactions" and "200 transactions," so confirm with the Department how transactions are counted. Our Arkansas sales tax guide covers registration and nexus in more detail. If you sell software, see our post on Arkansas SaaS sales tax.

The Department's due date page lists a monthly report, and its FAQ refers to a monthly (quarterly or annual) reporting form for registered businesses. The pages we reviewed do not publish the volume thresholds that decide which frequency a business gets, so check the frequency assigned to your account in ATAP or confirm it with the Department.

Larger businesses have extra payment deadlines. Under Arkansas law, businesses with average net sales of $200,000 or more per month must make prepayments of sales and use tax, and prepayments must be paid by electronic funds transfer. The Department says out-of-state sellers with taxable sales averaging more than $200,000 per month make prepayments equal to 80% of the monthly state liability twice each month.

Separately, taxpayers with an average total tax liability of $20,000 or more per month must pay by an electronic method. The Department selects them by a computer review in October before the year the requirement applies.

Before you start: get into ATAP

You need to be registered with the Department before you can file. Our sales tax permit overview explains the process. To use ATAP, click Sign Up on the login page and follow the access request instructions. For immediate access to an existing business account, the Department's FAQ says you provide:

• The taxpayer ID (FEIN, Social Security number, or ITIN).
• The ZIP code of the primary address on the account.
• Your email address and phone number.
• The account type and account ID.
• The amount of one of the last three payments made to the Department. For a new business whose last payment was the application fee, the FAQ says to enter $50.00, and $0.00 if you have made no payments.

ATAP uses two-step verification, with a security code sent by email, text message, or an authentication app. Access levels let you give a CPA or colleague permission to file, pay, or only view. Your account ID appears in the top right corner of a return or other Department correspondence.

Before filing, gather your gross receipts for the period, sales broken out by the city and county where the customer received the item, and records for any deductions you claim, such as sales for resale supported by a valid exemption certificate. For wholesale sales, see our Arkansas resale certificate guide for what to collect from buyers.

Step-by-step: filing a return in ATAP

1. Log in to ATAP and open the Customer page for your sales and use tax account.
2. Select the period. For the current period, click File a Return next to the period listed. Past due periods are listed in the Action Center on the Customer page.
3. Enter your sales and deductions. Report sales by the state, city, and county taxes that apply. Do not leave required lines blank.
4. Save a draft if you need to. Click Save Draft, then Finish Later. You can continue from More, then Search Submissions.
5. Review and submit. If a payment is required, you can submit it at the end of the filing process.
6. Print or save your copy. The Department says paper copies are for your own records and should not be sent to the Department.

Local and destination-based rate pitfalls

Arkansas sales tax has state, city, and county pieces. Since January 1, 2008, the Department's FAQ says local sales tax is based on the point of delivery. If the customer takes possession at your store, you collect local tax for the store location. If you deliver, ship, or mail the item, local tax is based on the delivery address. Taxable services, such as lawncare, use the jurisdictions where the service is performed.

Local tax caps on single transactions no longer apply except for motor vehicles licensed for highway use, aircraft, watercraft, and manufactured housing. For other sales, sellers collect state, city, and county taxes at their full rate on the invoice total.

The Department offers a free local tax rate lookup where you enter an Arkansas address, and its site lists city and county rate changes. Our Arkansas sales tax calculator shows current rates by location.

Due dates and the weekend rule

The Department publishes a yearly calendar. For 2026 it lists these dates for the monthly report and the two prepayments:

The monthly report dates in June, September, and December fall after the 20th, in months where the 20th is a Saturday or Sunday. The pages we reviewed do not spell out a general weekend rule, so use the Department's calendar for the exact date each year and consider filing early. The dates are also on our Arkansas sales tax due dates page.

Filing a zero return

If you had no sales for the current period, the Department's ATAP FAQ says to click File a Return Reporting No Activity to submit a zero dollar return. The pages we reviewed do not say whether a zero return is optional, so confirm with the Department if you are unsure whether your account must file for a period with no activity.

Amending a return

To view or amend a filed return in ATAP, click View Returns on the Customer page, then View or Amend Return for the period. The pages we reviewed do not state a time limit for amending, so confirm current rules with the Department before you amend an older period.

Payment methods

• ACH debit through ATAP: Pay as part of filing, or use the Pay With Bank Account link. You can save a payment source for future use. If your bank uses a debit block or filter, the Department's FAQ gives an originator ID to provide to your bank.
• ACH credit: You instruct your bank to send the payment in the CCD+TXP format. You must already be registered and have an account ID, and the payment must carry the correct tax type code.
• Credit card: Click Pay With Credit Card in ATAP. You are sent to a third-party site, ACI Payments, Inc., to complete the payment.

The Department says payments may take 2 to 3 business days to clear the bank. For penalty and interest calculations, it treats the payment as received on the date the payment request was submitted. Failure to pay by EFT when required carries a 5% penalty on the tax due.

Penalties and interest for late payment

The Department's general Penalty and Interest Charges guidance (Subject 702, revised December 2020) says interest and penalty are charged on unpaid tax from the original due date until payment, with interest at 10% per year. It describes a failure to file penalty of 5% of the tax owed for each month or part of a month, up to 35%, and a failure to pay penalty of 1% per month, up to 35%, with combined penalties capped at 35%. The guidance says interest and penalty are generally not waived. That document is written around the April 15 income tax due date, so confirm with the Department how it applies to sales and use tax returns.

The Department's EFT page adds two penalties that apply to sales tax accounts. Failing to make a required prepayment results in a 5% penalty, and failing to pay a prepayment by EFT results in a 5% penalty for each occurrence.

Common mistakes to avoid

• Missing the prepayment dates. If your average net sales reach $200,000 a month, two extra payments are due each month.
• Using one local rate for every sale. Delivered sales use the rate at the delivery address.
• Assuming the 20th never moves. The 2026 calendar shows later dates in some months.
• Counting only one threshold. Nexus can come from $100,000 in sales or 200 transactions.
• Paying at the last minute. ACH payments can take 2 to 3 business days to clear, although the Department dates the payment from when you submit it.
• Skipping the calendar. Check the Department's yearly due date table rather than assuming last year's dates.

If you receive a sales tax notice

A missed or late return often leads to a letter. Our Arkansas sales tax notices guide explains what notices from the Arkansas Department of Finance and Administration mean, why businesses usually receive them, and what to do next. It also points to how to ask for penalty relief where the state publishes a process. Check the date on the notice, match it to your filing period, and follow the instructions on the notice itself.
