Individuals in Alabama are required to report and pay their state income taxes using Form 40, Form 40A, or Form 40NR. For tax year 2010, returns must be filed by April 18, 2011 with the Alabama Department of Revenue (ADOR). Taxpayers who file late will be subject to penalties and interest charges ― however, there is an option to receive six extra months to file.

If you cannot file your Alabama state tax return by the due date, you do not need to officially request a tax extension. The Alabama Department of Revenue automatically grants six-month tax extensions, giving you until October 18, 2011 to file your return. In general, no extensions are permitted for more than six months (except in cases where taxpayers are out of the country).

It’s important to note that if you expect to owe state income tax this year, it must still be paid by the original deadline of April 18, 2011. You can make your state tax payment online (via ACH Debit, E-Check, or credit card) or with a check or money order (accompanied by Form 40-V (Individual Income Tax Payment Voucher).

For additional information, please visit the Alabama Department of Revenue’s Individual and Corporate Tax Division, under the "Automatic Extension" section.

Individuals, who will not meet the April filing deadline but expect to owe state income tax, must still pay their taxes by the original April due date.

You can make a payment online to the Alabama Department of Revenue (using ACH Debit, E-Check, or a credit card) through the Alabama Online Tax Payments system ― note this link will take you website not managed by FileLater.

If you choose to make your tax payment by check or money order, you must fill-out Form 40-V (Individual Income Tax Payment Voucher) and check the box for “Automatic Extension Payment.” Mail your Form 40-V to the Alabama Department of Revenue by April 18, 2011 to avoid incurring late fees.
