Alabama Income Tax Calculator
Estimate your 2025 combined federal and Alabama income tax — Alabama adds progressive state income tax on top of federal.
Income tax in Alabama
Alabama's brackets are tiny — the 5% top rate starts at just $3,000 of taxable income for single filers ($6,000 joint), so nearly everyone pays close to 5% at the margin. Alabama uniquely lets filers deduct federal income tax paid from state taxable income (not modeled here), which lowers real-world effective rates, and cities such as Birmingham levy roughly 1% occupational taxes that are also excluded.
