Need to mail your Arkansas state tax return? Here’s exactly where to send it, plus tips to avoid delays.
Quick Fix Summary
Pick the right P.O. box based on your balance:
- Refund due: Arkansas State Income Tax, P.O. Box 1000, Little Rock, AR 72203-1000
- Tax due: Arkansas State Income Tax, P.O. Box 2144, Little Rock, AR 72203-2144
- No tax due (zero balance): Arkansas State Income Tax, P.O. Box 8026, Little Rock, AR 72203-8026
What’s the deal with these separate P.O. boxes anyway?
Arkansas splits mailed state returns into three Little Rock lockboxes. The right box depends entirely on whether you owe money, are getting a refund, or broke even. Send it to the wrong one? Congratulations, you just added weeks to your processing time.
How do I figure out which box to use?
Look at line 42 on your AR1000 form. Negative number? That’s your refund, so use P.O. Box 1000. Positive number? You owe, so hit P.O. Box 2144. Zero? Then P.O. Box 8026 is your destination. Honestly, this is the simplest part of the whole process.
What should I write on the envelope?
Just the correct P.O. box number, written clearly. “PO Box 1000” works fine—no need for fancy abbreviations like “P.O.B. 1000.” Print it if you’re worried about smudges, but handwriting is totally acceptable.
Do I need to include anything else with my return?
If you owe money, attach a check made out to “Arkansas State Treasury.” Write your Social Security number and “2025 AR1000” on the check so they know who’s paying. Expecting a refund? Skip the mailing hassle and set up direct deposit instead.
How much postage should I put on the envelope?
One Forever stamp? Probably not enough. Weigh your envelope first. As of 2026, First-Class rates are $0.68 for the first ounce, then $0.24 for each extra ounce USPS Notice 2025. Better to overestimate than get a “postage due” notice.
Where’s the best place to drop off the envelope?
Any USPS location will do. Ask for a free Certificate of Mailing (PS Form 3817) when you drop it off. Hold onto that receipt—you’ll want proof until your refund shows up or your payment posts.
What if I sent it to the wrong box?
Double-check the box number against the official list on the Arkansas Department of Finance and Administration (DFA) website at www.dfa.arkansas.gov. The good news? The boxes haven’t changed since 2023, so odds are you just misread the instructions.
How can I track my mailed return?
If you used tracking, log in to USPS Package Tracking and enter your label number. Most Little Rock deliveries take 3–5 business days once it’s scanned.
Who do I call if my refund is late?
Dial the DFA refund hotline at 1-800-882-9275 (toll-free) or 501-682-1100. They can confirm whether your return was received and processed within 7–10 business days of acceptance.
Is there a better way to file than mailing?
Absolutely. Use the Arkansas Taxpayer Access Point (ATAP) at https://atap.arkansas.gov. E-filed returns usually process in 7–10 days—versus 6–8 weeks for paper returns. It’s faster, cheaper, and way less stressful.
How do I speed up my refund?
Sign up for direct deposit on your AR1000 form. Once accepted, refunds hit your account in 3–5 business days. No waiting for a check to arrive in the mail.
Should I use certified mail for payments?
Only if you’re mailing a check. Certified Mail with return receipt gives you proof of delivery. Keep the green card until the payment shows up in your ATAP account—that way you know it posted.
What’s the safest way to keep records?
Snap a photo or scan your signed AR1000 before mailing it. Save the barcode image too—once processed, it contains your confirmation number. (Trust me, you’ll thank yourself next tax season.)
