Understanding the state tax deadline and refund process is important for every taxpayer in Arkansas. The Arkansas Department of Finance and Administration (DFA) manages income tax filings, extensions, and refunds for the state.
In 2026, most taxpayers must file their 2025 Arkansas individual income tax return by the regular deadline, but there are special rules and extension options if you cannot complete your return by that date.
Knowing these rules helps you avoid penalties and makes sure you get any refund you expect.
What Is the Arkansas State Tax Filing Deadline for 2026?
For most individual taxpayers, the deadline to submit 2025 state income tax returns in Arkansas is April 15, 2026. You must file by that date to avoid penalties and interest on any tax you owe.
If April 15 falls on a weekend or holiday, the due date may shift to the next business day.
This deadline applies regardless of whether you file electronically or by mail. If you mail your return, it must be postmarked by April 15 to be considered timely.
The DFA instructions also remind filers to attach all required forms and sign the return for it to be accepted.
Can I Get More Time to File My Arkansas Tax Return?
Yes. Arkansas allows extensions of time to file your return, but not extensions to pay any tax owed. If you cannot file by April 15:
- You can request an automatic federal extension by submitting IRS Form 4868 by the April 15 deadline. Arkansas will automatically honor the federal extension for your state return. This typically gives you until November 15, 2026 to file your Arkansas return.
- If you prefer not to use the federal extension, you can request a state extension by filing Arkansas Form AR1055 by April 15. If approved, this extension also gives you extra time to submit your return, usually up to 180 days. You must attach the approved extension to your return when you file.
Remember: Even with an extension to file, any tax owed must still be paid by April 15 to avoid penalties and interest. Extensions do not delay payment deadlines.
Are There Special Deadline Extensions for 2026?
Yes. For tax year 2024 returns filed in 2025, the state previously issued a special extension out to December 3, 2025 due to severe weather in 2025.
Taxpayers had to attach IRS disaster relief documentation or check the federal extension box on their return to use that extended deadline. Penalties did not apply if the return was filed by December 3, 2025, but estimated payment deadlines were not extended.
For 2025 returns due in 2026, no statewide disaster extension has been announced as of early 2026. The standard due date remains April 15, 2026, unless you secure an extension as described above.
Always check the official DFA deadlines page for updates that may apply to your filing year.
How Do I File My Arkansas State Tax Return?
You can file your Arkansas state return in several ways:
- Electronically (e‑file) using tax software or through a tax professional. E‑filing is usually faster and more reliable.
- Paper mailing your return to the DFA address printed in the instructions. Make sure it is postmarked by the deadline.
- Through a preparer who handles both federal and state filings for you.
E‑filing generally results in faster processing and refunds compared with paper returns. Always keep copies of your filed return and all supporting documents for your records.
When Should I Expect My Arkansas Tax Refund?
If you are due a refund after filing your 2025 Arkansas state return in 2026, most refunds are processed after the state accepts your return. According to official DFA guidance:
- E‑filed and accurate returns usually get refunds within about 10 business days after the return is accepted.
- Paper‑filed returns often take longer, typically 6 to 8 weeks from the date you mailed them.
These are general guidelines. The exact timing of refunds can vary based on return volume and whether additional review is needed.
How Do I Check the Status of My Arkansas State Tax Refund?
To check your refund status, visit the Arkansas Taxpayer Access Point (ATAP) on the DFA website. You will need your Social Security number, the tax year, and the exact refund amount from your return.
The tool provides status updates from received through processing and issued stages.
If you prefer to check by phone, you can call the DFA refund hotline. The contact numbers are available on the DFA income tax page. These resources help you track your refund once your return has been filed.
What Happens If I Miss the Filing Deadline?
If you miss the April 15, 2026 deadline and do not have an approved extension, penalties and interest may apply. Penalties can be charged based on how late your return is filed and how much tax you owe. Interest accrues from the original due date until payment is made in full.
If you owe tax but cannot pay the full amount by April 15, file your return on time and pay as much as you can.
The DFA will assess interest and penalty only on the unpaid balance. Filing on time even with partial payment can reduce penalties.
