When filing an amended Alabama individual income tax return, you must complete Form 40 (or Form 40NR for nonresidents) and check the “Amended” box. This is required if you discover any changes to your income, deductions, or credits after filing your original return. You must also attach a detailed explanation page outlining all changes made to your return.
