Alabama Tax Calculator

Alabama taxes income using a tiered bracket system, meaning different portions of your paycheck are taxed at different rates as your income rises. One notable feature: Alabama is among a small handful of states that let you deduct the federal income tax you paid from your state taxable income, which can meaningfully lower your bill. This calculator applies Alabama's brackets to your entered income and shows both your marginal and effective state rate.

How Alabama income tax works

  • Alabama applies a tiered bracket schedule, so only the portion of income inside each bracket is taxed at that bracket's rate.
  • A federal-income-tax deduction is available, which can lower effective Alabama taxable income for filers who claim it.
  • The calculator shows your marginal rate (the rate on your last dollar) alongside your overall effective rate.

Frequently asked questions

How is Alabama income tax calculated?

Alabama uses a tiered bracket system, so income is taxed in layers rather than at one flat rate. The calculator walks your entered income through each bracket to compute the total state tax owed and shows the equivalent marginal and effective rates.

Does Alabama tax Social Security benefits?

No. Alabama excludes Social Security benefits from state taxable income entirely, regardless of your total income.

Can I deduct federal taxes on my Alabama return?

Yes — Alabama is one of only a few states that allow a deduction for federal income taxes paid, which can meaningfully reduce your Alabama taxable income and lower your effective state rate.

How much state tax will I pay in Alabama?

It depends on your taxable income and any federal-tax deduction you claim. Enter your income into the calculator above to see your exact bracket-by-bracket breakdown and total state tax.
