My Alabama Taxes, usually shortened to MAT, is the Alabama Department of Revenue’s online portal for individual filers. Inside your account you can prepare and file your state return for free, pay a balance by bank draft or card, view past returns and department letters, update your address, grant access to a preparer, and check the status of a refund. It’s the same system the department uses on its end, so filings and payments go straight to ADOR without a third party in the middle.
Creating Your MAT Account
Go to the My Alabama Taxes portal and choose the option to sign up. You’ll need your Social Security Number and the adjusted gross income from your current or prior-year Alabama return to confirm your identity.1Alabama Department of Revenue. My Alabama Taxes Sign-Up If you can’t find last year’s return, the number you want appears on the line labeled “Alabama Adjusted Gross Income” on Form 40.
Once you’re in, the portal gives you access to previously filed returns, official ADOR correspondence, address changes, preparer authorizations, and a secure messaging feature for questions about your account.2Alabama Department of Revenue. Individual Income Tax Electronic Filing Options For most account questions, that secure message is faster than calling.
Filing Your Return Through MAT
The main form for individual filers is Form 40, which covers full-year residents, part-year residents, and nonresidents with Alabama-source income. All Alabama taxpayers can prepare and submit Form 40 directly through MAT at no cost.2Alabama Department of Revenue. Individual Income Tax Electronic Filing Options You’ll be prompted for direct deposit information during the process if you’re expecting a refund.3Alabama Department of Revenue. Choose Direct Deposit
The deadline is April 15, or the next business day when the 15th falls on a weekend or holiday. Alabama grants an automatic six-month filing extension without a separate form, but the extension only covers paperwork. Any tax you owe is still due April 15, and interest and penalties start running on unpaid balances after that date.4Alabama Department of Revenue.

Other Ways to File
If you’d rather use commercial software, ADOR authorizes providers including TurboTax, H&R Block, TaxSlayer, TaxAct, FreeTaxUSA, and Cash App Taxes, among others.2Alabama Department of Revenue. Individual Income Tax Electronic Filing Options Some offer free state filing depending on your income and the complexity of your return. Paper filing is still allowed, but paper returns take longer to process and are more error-prone than an e-filed return.
Paying What You Owe
Payments run through MAT as well. Signed-in users can pay by ACH debit, pulling funds straight from a bank account. If you don’t have an account, the portal’s “Pay a Bill” feature handles one-time payments. Credit and debit cards are accepted through MAT too, with a third-party processing fee.5Alabama Department of Revenue. My Alabama Taxes FAQs
Checks and money orders can still be mailed to the address printed on your invoice or return. One thing to watch: under Alabama Code Section 41-1-20, any taxpayer whose payment for a given period reaches $750 or more is required to pay electronically.6Alabama Department of Revenue. EFT Threshold of $750
Estimated Payments
If you expect to owe $500 or more after withholding and credits, you’re required to make quarterly estimated payments on Form 40ES.7Justia Law. Alabama Code Title 40 Chapter 18 40-18-83 – Payment of Estimated Tax Installments are due April 15, June 15, September 15, and January 15 of the following year. Skipping them can trigger underpayment penalties even if you settle the full balance when you file.
Checking Your Refund
MAT has a “Where’s My Refund” tool. You’ll need your Social Security Number, the tax year, and the exact refund amount from your return. There’s also a 24-hour refund hotline at 1-855-894-7391.8Alabama Department of Revenue. Where’s My Refund Because I Have Not Received It Yet
ADOR asks that you wait at least six weeks after e-filing before checking. Returns flagged for review or identity verification typically take eight to ten weeks. If yours is pulled for additional review, you’ll get a letter asking for information, and the refund won’t move until you respond.8Alabama Department of Revenue. Where’s My Refund Because I Have Not Received It Yet
Identity Confirmation Quiz
Some filers receive a letter asking them to complete an Identity Confirmation Quiz before the refund is released. The quiz takes about five minutes and requires your Social Security Number, the Letter ID from the top-right corner of the notice, and a current email address. Questions come from personal information ADOR uses to confirm you filed the return.9Alabama Department of Revenue. Alabama Taxpayer Identity Protection Program To verify by phone instead, call 1-800-535-9410.
When the Refund Is Smaller Than Expected
A short refund usually means part of it was intercepted for an outstanding debt. Alabama can offset refunds for past-due child support, spousal support, and unpaid state tax balances. Child support intercepts require a minimum arrearage of $500.10Cornell Law School / Legal Information Institute. Alabama Admin Code Rule 660-3-6-.01 – General Intercept Information The federal Treasury Offset Program can also redirect a state refund toward certain federal debts. Either way, ADOR or the intercepting agency will send a notice explaining the amount and the reason.
If You File or Pay Late
Late filing and late payment carry separate penalties, and they can stack. The late filing penalty is the greater of 10 percent of the additional tax due with your return or $50. If you file late but don’t owe any tax, the penalty doesn’t apply to individual returns.11Alabama Legislature. Alabama Code Title 40 Revenue and Taxation 40-2A-11 – Civil Penalties Levied in Addition to Other Penalties Provided by Law
The late payment penalty is 1 percent of the unpaid tax for the first month, plus another 1 percent for each month or partial month after that, capped at 25 percent.11Alabama Legislature. Alabama Code Title 40 Revenue and Taxation 40-2A-11 – Civil Penalties Levied in Addition to Other Penalties Provided by Law Interest also runs on unpaid balances at a rate that adjusts quarterly. For the first quarter of 2026, the rate is 7 percent.12Alabama Department of Revenue. Quarterly Interest Rates Interest starts on the original due date whether or not you took the automatic extension.
Amending a Return
MAT does not handle amendments. If you need to correct a filed return, you’ll use Form 40X, enter the corrected figures, and attach a written explanation for each change along with any supporting documents. Form 40X has to be printed, signed, and mailed to the Alabama Department of Revenue, Individual & Corporate Tax, P.O. Box 327464, Montgomery, AL 36132-7464.13Alabama Department of Revenue.
