Alabama residents may choose to itemize deductions on their state income tax return (Form 40) instead of claiming the standard deduction. Itemized deductions are similar to those allowed at the federal level, but Alabama may treat certain items differently. To itemize, taxpayers must check box “a” on line 11 of Form 40 and complete and attach Schedule A.
Eligible Itemized Deductions
- Medical and dental expenses — Deductible if they exceed a certain threshold (similar to federal rules).
- Taxes — Includes real estate and personal property taxes paid in Alabama.
- Charitable contributions — Donations to qualified organizations may be deductible.
- Home mortgage interest — Interest paid on a qualified home mortgage is deductible.
- Miscellaneous deductions — Certain other expenses may qualify, subject to Alabama rules.
Special Rules for Part-Year Residents
- Part-year residents must prorate their itemized deductions to reflect only expenses incurred during their period of Alabama residency.
- Only income earned while residing in Alabama is reportable, and deductions must align with that residency period.
- Federal tax liability is prorated using a percentage of Alabama adjusted gross income (AGI) to federal AGI to determine the deductible amount on line 12 of Form 40.
Nonresidents and Form 40NR
- Nonresidents who earned income from Alabama sources must file Form 40NR if their gross income from Alabama exceeds the prorated personal exemption.
- Itemized deductions are allowed on Form 40NR, but only for expenses directly related to Alabama income.
