File Your Tax Return Now →Alabama’s Automatic Personal Income Tax Extension
Alabama taxpayers who need extra time to complete their state return can take advantage of an automatic extension – no application, no separate form, no approval process required. The Alabama Department of Revenue (ALDOR) grants a six-month extension to file, moving your deadline from April 15 to October 15. What the extension does not move is your payment due date.
Original Deadline: April 15, 2026
Payment of any taxes owed is due by this date – even with the extension in place.
File by October 15, 2026
Your Alabama return must be filed by this date under the automatic six-month extension.
Payment Is Still Due by April 15
While the extension to file is automatic, it does not extend the time to pay. Any taxes owed are still due by April 15, 2026. If full payment is not received by this date, you may be subject to interest and penalties on the unpaid balance. Estimating your tax liability and paying on time is essential to avoid unnecessary charges.
Late Filing and Payment Penalties
Failure to file carries a penalty of the greater of $50 or 10% of unpaid tax. Failure to pay results in 1% per month up to 25%. Paying your balance by April 15 eliminates the failure-to-pay penalty entirely.
How to File Your Alabama Return After an Extension

- ✓Gather your tax documents (W-2s, 1099s, receipts, etc.)
