Alabama state income tax rates and calculator

Updated Mar. 27, 2025

Alabama taxes income using a progressive, or graduated, rate system, with rates ranging from 2 percent to 5 percent across three tax brackets.

Alabama personal income tax rates for 2024

For income earned in 2024 and filed on tax returns in 2025, you’ll pay the tax rates noted in the table below.

Like the U.S. tax system, Alabama has a graduated, or progressive, tax system. That means your marginal tax rate is the top rate you pay, but your effective, or actual, tax rate is a blend of tax rates. Usually, your effective tax rate will be lower than your marginal rate.

For example, a single or head-of-household filer in Alabama with $30,000 in taxable income in 2024 will pay a 2 percent tax rate on their first $500 of income, a 4 percent tax rate on income that falls between $500 and $3,000 (in other words, on $2,500 of income), and 5 percent on any income over $3,000 (in our example, that means a 5 percent rate on $27,000).
