How does this calculator work?
Alabama state income tax uses three brackets (2 %/4 %/5 %) on taxable income after standard deduction, personal exemption, and the unique Alabama deduction for federal taxes paid. For a single filer in 2025 with $60 000 gross and $8 000 federal tax paid, state taxable income is roughly $47 500, yielding about $2 275 in Alabama state tax (≈ 3.8 % effective rate).
Formula
How this is calculated
Alabama levies a graduated state income tax on three brackets: 2 % on the first $500 of taxable income, 4 % on the next $2 500 ($500–$3 000), and 5 % on everything above $3 000. These brackets have been unchanged for decades and apply to all filing statuses. The 2025 standard deduction is $2 500 for single filers, $7 500 for married filing jointly, $3 750 for married filing separately, and $4 700 for head-of-household. A personal exemption of $1 500 (single/MFS) or $3 000 (MFJ/HOH) further reduces taxable income, plus $1 000 per dependent.
A notable Alabama-specific feature is that federal income taxes paid are deductible from Alabama AGI before computing state tax — this can significantly reduce state liability for higher earners who pay substantial federal tax. This calculator deducts your estimated federal tax before applying the brackets.
FICA payroll taxes (Social Security 6.2 % on wages up to $176 100 and Medicare 1.45 % on all wages for 2025) are withheld from most wages separately from state income tax and are shown here for a complete picture. Local (city/county) taxes, which vary across Alabama, are not included — check your municipality separately. All rates shown are 2025 estimates; verify with a tax professional for your specific situation.
Frequently asked questions
Yes — Alabama is one of a handful of states that allows taxpayers to deduct actual federal income taxes paid on their Alabama return. This meaningfully lowers Alabama taxable income for earners who pay significant federal tax. The deduction uses taxes actually paid, not withheld, so it is based on your prior-year federal return or current-year estimates.
Progressive — Alabama taxes income in three brackets: 2 % on the first $500, 4 % on $500–$3 000, and 5 % on everything above $3 000 of taxable income. These bracket thresholds are the same for all filing statuses. The effective rate is always lower than 5 % because the lower brackets apply first.
Some Alabama cities levy their own occupational tax. Birmingham charges 1 % on earned income, and a number of other municipalities have similar levies. These city taxes are separate from state income tax and are not included in this calculator — check with your city or employer for local rates.
