Alabama Tax Calculator
Alabama has a progressive income tax with a top rate of 5% — but the highest combined sales tax in the Southeast at ~9.15%.
Alabama's three-bracket income tax ranges from 2% to 5%, with the top rate kicking in above $3,000 of taxable income — one of the most graduated low-income thresholds in the country. The state has one of the highest combined sales tax rates in the Southeast at roughly 9.15% (4% state + up to 7% local additions, with some cities like Birmingham and Montgomery exceeding 10%). Property taxes are the lowest in the US at ~0.39% effective, reflecting the state's reliance on consumption taxes and income tax rather than real estate taxation. Alabama offers retirement-income exemptions for residents 65+ on most pension and IRA distributions up to a tiered limit, and a federal-standard-aligned deduction ($3,000 single). The state exempts Social Security benefits. Alabama's overall tax structure is regressive but moderate at higher incomes; combined with its low cost of living, the state attracts retirees and remote workers seeking affordability over tax breaks.
