Alabama capital gains tax overview
Alabama capital gains tax planning starts with the federal rules, then layers on Alabama's own treatment (graduated income tax (top rate up to 5%)). This calculator estimates both so you can see a combined effective rate before you sell stocks, crypto, real estate, or other capital assets.
Federally, short-term gains (held one year or less) are taxed as ordinary income, while long-term gains generally use 0%, 15%, or 20% preferential rates for tax years 2025 and 2026. High earners may also owe the 3.8% Net Investment Income Tax when MAGI exceeds the IRS threshold for their filing status.
Alabama generally taxes capital gains under its graduated income-tax framework. For planning estimates we apply Alabama's top modeled rate (graduated income tax (top rate up to 5%)) to taxable gains. Your actual marginal state rate may be lower depending on total Alabama taxable income.
Alabama figures in this model are drawn from the official source we cite for the state: https://www.revenue.alabama.gov/. Confirm the current-year statute or agency page before you file — rates and special rules can change.

FAQ

How does Alabama tax capital gains?
Alabama generally taxes capital gains under its graduated income-tax framework (Graduated income tax (top rate up to 5%)). For planning we apply the top modeled rate to taxable gains; your actual Alabama marginal rate may be lower depending on total taxable income.
Is the Alabama amount on this calculator exact?
No. Graduated states are estimated at the top modeled rate, not a full multi-bracket state return. Federal tax and NIIT are stacked separately. Federal short-term and long-term capital gains tax, and the 3.8% Net Investment Income Tax when MAGI exceeds the IRS threshold, can still apply.
