Alabama State Income Tax Overview
Alabama has a graduated state income tax with three brackets ranging from 2% to 5%. Single filers pay 2% on income up to $500, 4% on income from $501 to $3,000, and 5% on income above $3,000. Married filers have slightly wider brackets, with the 5% top rate kicking in above $6,000. Alabama allows a standard deduction that phases out at higher income levels, and the state also permits a deduction for federal income taxes paid - a relatively rare benefit that can meaningfully reduce your Alabama taxable income. Residents should also factor in county and municipal occupational taxes that apply in many parts of the state.
Alabama Income Tax Brackets (2025)
These are the Alabama state income tax brackets for tax year 2025. Alabama applies the same brackets to all filing statuses. Only the income within each bracket is taxed at that rate -- not your entire income.
| Taxable Income | Tax Rate |
|---|---|
| $0 - $500 | 2% |
| $500 - $3,000 | 4% |
| Over $3,000 | 5% |

Understanding Your Alabama Tax Estimate
Your results combine two separate bills: federal tax owed to the IRS, and Alabama state tax owed to the Alabama Department of Revenue. The state return is filed separately from your federal Form 1040, with a state filing deadline of April 15. For the mechanics of how bracket math actually works -- why your effective rate is almost always lower than your top bracket -- see our marginal vs. effective tax rate guide.
Lowering Your Alabama Bill
Pre-tax retirement contributions reduce your federal and Alabama taxable income in the same move -- see our 401(k) contribution limits and HSA limits guides for the current caps. Beyond that, Alabama-specific credits and deductions that don't exist at the federal level are listed at the Alabama Department of Revenue -- worth checking, since these are easy to miss if you only look at federal guidance.
