Alabama Standard Deduction
The Alabama standard deduction is a flat amount you can subtract from your gross income before Alabama income tax is calculated, instead of itemising individual deductions. This page shows the Alabama standard deduction for tax year 2025 by filing status, sourced directly from the Alabama Department of Revenue, and calculates your Alabama taxable income after the deduction. Enter your gross income and choose your filing status to see the deduction that applies and the taxable income that remains. Most filers take the standard deduction because it is simpler and, for many, larger than their itemisable deductions. You should itemise only if your allowable Alabama itemised deductions add up to more than the standard amount. The standard deduction is separate from the federal standard deduction the IRS applies to your federal return, and from any personal exemptions or credits Alabama provides. Use this alongside the Alabama income tax calculator to see how the deduction flows through to your final state tax. All figures here are the official published amounts; nothing is estimated.
The Alabama standard deduction for 2025 is $3,000.00 (single) and $8,500.00 (married filing jointly). On $60,000.00 of gross income, a single filer has $57,000.00 of Alabama taxable income.

Can Alabama residents deduct federal income taxes on their state return?
Yes. Alabama is one of only a handful of states that allows a deduction for federal income taxes paid. This deduction, under Alabama Code §40-18-15, can significantly reduce Alabama taxable income for taxpayers who owe substantial federal tax. The deduction applies to the actual federal income tax liability, not estimated payments, and is claimed on the Alabama return.
Does Alabama have any other notable tax features?
Alabama does not tax Social Security benefits. Food purchased for home consumption is subject to Alabama sales tax but exempt from some local sales taxes, making Alabama notable for still taxing groceries at the state level (though the state grocery rate was reduced to 3% in 2023). Alabama's income tax bracket thresholds are very low and have not been updated in decades, meaning most taxpayers quickly reach the 5% top bracket.
