What this tool does
Computes Alabama state tax for the 2025 full-year resident table above 100,000 of taxable income: the table’s base amount plus 5% of the excess.
How to use it
- Enter taxable income after deductions and exemptions — not gross income.
- Enter 1 for married filing jointly, or 0 otherwise (single, married filing separately, head of household).
- Run it for the tax amount.
Worked example
Taxable income of 120,000 filing separately gives (120,000 − 100,000) × 5% + 4,958 = 5,958. Filing jointly uses a base of 4,918 instead.

- Can I use it below 100,000 of taxable income?
- No. This table covers the above-100,000 band. Lower bands use a different schedule — consult the official materials.
- Does it include federal tax?
- No. It computes Alabama state tax only, excluding federal income tax, payroll taxes, and local taxes.
What this tool does not cover
Based on the 2025 schedule, and tax law changes. It does not compute deductions or exemptions, so you must determine taxable income first. Verify against the state tax authority before filing.
