๐๏ธ What is the Alabama Income Tax?
Alabama income tax uses a progressive three-bracket system with rates of 2%, 4%, and 5%. The 5% top rate applies to virtually all income above the first few thousand dollars, making Alabama's tax structure effectively close to a flat 5% for most wage earners. For 2025, single filers enter the 5% bracket at just $3,000 of taxable income, and married couples enter it at $6,000. Alabama's top rate of 5% is among the lower rates in the southeastern United States and well below states like California (13.3%) or New York (10.9%).
One of Alabama's most distinctive tax features is the deductibility of federal income taxes paid. Alabama is one of only three states in the US that allows taxpayers to deduct their actual federal income tax liability from their Alabama taxable income before applying state rates. This deduction significantly reduces Alabama's effective tax burden for middle and higher earners. On a $100,000 income, federal tax of roughly $13,700 reduces Alabama taxable income by that full amount, saving about $685 in Alabama state tax compared to a system without this deduction.
Alabama's standard deduction phases out as income rises, which is an unusual design. A single filer earning $20,499 or less receives the full $2,500 deduction, but that deduction shrinks by $25 for every $500 of additional income. By the time income reaches $60,499, the deduction has fallen to its minimum of $500. The personal exemption of $1,500 for single filers and $3,000 for joint filers does not phase out, providing a consistent reduction at all income levels. Together, the phaseout mechanics mean that moderate-income earners effectively have more Alabama taxable income relative to their gross wages than the headline deduction numbers suggest.
Alabama has no state disability insurance (SDI) deduction, unlike California (1.1%), New York (0.5%), or New Jersey. Alabama workers pay only state income tax and federal FICA on top of federal income tax. Several Alabama cities, including Birmingham and Gadsden, levy a 1% local income tax on wages earned within their limits, which this calculator does not include. This tool estimates annual tax liability for standard wage earners using the 2025 Alabama Department of Revenue brackets and the 2025 IRS federal brackets.
