Calculate Alabama state income tax with current state brackets, the Alabama standard deduction chart, personal and dependent exemptions, the federal tax deduction, and optional local tax.
Alabama uses a simple three-bracket state income tax system with rates of 2%, 4%, and 5%, but the taxable-income calculation is less simple than the rate table suggests. Alabama allows a deduction for federal income tax paid, uses filing-status-based personal exemptions, and applies the state's standard deduction chart instead of one flat deduction amount.
This calculator estimates Alabama tax using the current bracket structure published by ALDOR, the standard deduction chart tied to Alabama total income, the $1,500 or $3,000 personal exemption, the $300 dependent exemption, and any optional local occupational or income tax you enter. It is a planning tool, not a completed Alabama Form 40 return.
Because Alabama allows a federal tax deduction and some localities impose additional tax, the same gross income can produce very different state results depending on your filing status, federal liability, and work location.
Alabama's federal tax deduction, standard deduction chart, personal exemptions, and optional local taxes make quick mental estimates unreliable. This calculator brings those pieces together so you can estimate state liability and take-home pay without hand-building the Alabama worksheet.
Alabama Taxable Income = Gross Income − Deductions − Personal Exemption − Dependent Exemption − Federal Tax Deduction Single/Separate brackets: 2% (first $500), 4% ($500–$3,000), 5% (over $3,000) Married/Head of Family brackets: 2% (first $1,000), 4% ($1,000–$6,000), 5% (over $6,000) Personal Exemption = $1,500 single/MFS or $3,000 MFJ/Head of Family Dependent Exemption = $300 per dependent Standard Deduction = Alabama chart amount based on filing status and Alabama total income
Result: $2,585 state tax
With $65,000 income, the Alabama single standard deduction chart amount is $2,000. After the $1,500 personal exemption and a $9,000 federal tax deduction, taxable income is $52,500. Alabama tax is about $2,585: 2% on the first $500, 4% on the next $2,500, and 5% on the remaining taxable income.
Check the filing status first, then make sure the deduction amount matches the Alabama standard deduction chart or your actual itemized deductions. Alabama allows a federal income tax deduction, so the federal-tax input can materially change the final state result even when gross income stays the same.
The biggest errors are treating the Alabama standard deduction as one flat number, using the wrong filing status, or forgetting a local occupational tax. If the result looks off, recheck the deduction amount, the federal-tax input, and whether your city or county charges a local tax.

This calculator estimates Alabama taxable income by subtracting the entered deduction amount, the filing-status-based personal exemption, the $300-per-dependent exemption, and the entered federal income tax deduction from gross income. It then applies Alabama's 2%, 4%, and 5% bracket structure and adds any user-entered local tax as a percentage of gross income.
The page shows the current Alabama standard deduction chart amount as a hint, but it still lets you override that number with itemized deductions or another scenario input. It is a planning estimate rather than a full Form 40 preparation workflow and does not model every ALDOR credit, pension adjustment, or county-level edge case.
Alabama has three brackets: 2% on the first $500 ($1,000 married), 4% on the next $2,500 ($5,000 married), and 5% on income above $3,000 ($6,000 married). Use the bracket table to confirm where your taxable income lands.
Yes. Alabama allows a deduction for federal income tax paid or accrued, which is unusual among states. This page treats the federal-tax field as a user-supplied planning input rather than capping it at an arbitrary amount.
Alabama uses a standard deduction chart rather than one flat amount. The deduction depends on filing status and Alabama total income, and the chart is the official reference for tax years ending 12/31/2007 and later.
Some Alabama cities and counties levy an occupational or income tax. Birmingham charges 1%, for example. Check with your local municipality for exact rates.
Alabama gives a $1,500 personal exemption to single and married filing separately filers, and a $3,000 personal exemption to married filing jointly and head of family filers. The dependent exemption is $300 per dependent.
Alabama does not tax Social Security benefits and offers favorable treatment for pensions and retirement income, though some types may be partially taxable. Use this checkpoint when values look unexpected.
