Alabama Capital Gains Tax Calculator
Alabama taxes capital gains as ordinary income at the state level, which means a gain on selling shares, property or other investments is added to your other income and taxed using the Alabama income tax brackets, with no separate preferential long-term rate like the federal system provides. This calculator estimates the Alabama state tax on a capital gain by stacking the gain on top of your other taxable income and applying the sourced Alabama Department of Revenue brackets for tax year 2025, then taking the difference. Enter your gain, your other annual taxable income and your filing status to see the state tax attributable to the gain and the effective rate on it. The result is the Alabama state portion only; federal capital gains tax, which has separate short-term and long-term rates set by the IRS, is calculated separately. Because the gain stacks on your other income, the same gain is taxed at a higher rate the more you already earn. Some states provide specific exclusions or preferential treatment for certain gains; this tool uses the standard ordinary-income method and links the Alabama Department of Revenue so you can confirm any special rule that applies to you.

What are Alabama's income tax rates for 2025?
Alabama uses a graduated three-bracket income tax under Alabama Code §40-18-5. For single filers: 2% on the first $500, 4% on $501-$3,000, and 5% on income over $3,000. For married filing jointly: 2% on the first $1,000, 4% on $1,001-$6,000, and 5% on income over $6,000. Head of household and married filing separately use the single brackets.
What is Alabama's standard deduction?
Alabama's standard deduction is $3,000 for single filers and married filing separately, $8,500 for married filing jointly, and approximately $4,700 for head of household. These amounts phase out for higher-income taxpayers (roughly above $100,000 of income). Alabama also provides personal exemptions of $1,500 for single filers and $3,000 for married filing jointly, plus $1,000 per qualifying dependent, under Alabama Code §40-18-19.
Can Alabama residents deduct federal income taxes on their state return?
Yes. Alabama is one of only a handful of states that allows a deduction for federal income taxes paid. This deduction, under Alabama Code §40-18-15, can significantly reduce Alabama taxable income for taxpayers who owe substantial federal tax. The deduction applies to the actual federal income tax liability, not estimated payments, and is claimed on the Alabama return.
Does Alabama have any other notable tax features?
Alabama does not tax Social Security benefits. Food purchased for home consumption is subject to Alabama sales tax but exempt from some local sales taxes, making Alabama notable for still taxing groceries at the state level (though the state grocery rate was reduced to 3% in 2023). Alabama's income tax bracket thresholds are very low and have not been updated in decades, meaning most taxpayers quickly reach the 5% top bracket.
