Automatic Extension Granted by Alabama

The Alabama Department of Revenue (ALDOR) grants an automatic six-month extension for filing state income tax returns. Taxpayers who cannot file by the original due date of April 15, 2026, are automatically extended until October 15, 2026. No application or form submission is required to receive this extension to file.

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, taxpayers 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.

How to Make Extension Payments

Alabama offers two online payment methods:

• ACH Debit: Use myalabamataxes.alabama.gov. No fee. Do not use Form 40V for ACH payments.
• Credit Card: Pay via officialpayments.com (Jurisdiction Code 1100) or paystatetax.com/al. Phone: 1-800-272-9829. A convenience fee applies.

Using Form 40V

For mail-in payments, use Form 40V to ensure your payment is properly credited.

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%, plus an additional 1% per month after 30 days from notice and demand. Paying your balance by April 15 eliminates the failure-to-pay penalty entirely.

1. 1Gather your tax documents (W-2s, 1099s, receipts, etc.)
