Alabama Income Tax Calculator 2026 – how it works
Alabama individual income tax is calculated using a progressive bracket system. Taxable income is first reduced by applicable deductions and exemptions, then taxed in segments at increasing rates. Income up to $500 is taxed at 2%, income from $501 to $3,000 is taxed at 4%, and income above $3,000 is taxed at 5%. Because the top rate applies at relatively low income levels, most taxable income beyond the initial brackets is subject to the 5% marginal rate.
Examples
Under Alabama’s progressive structure, moving into a higher bracket does not mean all income is taxed at the higher rate. For example, if taxable income exceeds $3,000, only the portion above $3,000 is taxed at 5%, while earlier portions remain taxed at 2% and 4%. As income increases further, the total tax rises primarily due to the larger share taxed at the top marginal rate.
Limitations and important notes
This calculator provides a simplified estimate based on Alabama’s published tax brackets, a base standard deduction, and a single personal exemption amount. It does not account for all deductions, credits, income adjustments, phase-out calculations, federal income tax deductibility, or special residency rules that may apply. Results may differ from a final Alabama return.
