Alabama capital gains tax overview

Three brackets: 2% up to $500 (single), 4% up to $3,000, 5% above.

No preferential long-term rate: Unlike the federal system, Alabama taxes capital gains identically to ordinary income at the state level. This makes timing strategies especially important for Alabama residents with large gains.

Federal + Alabama combined rates

Your total capital gains tax bill includes both layers — federal and state. Here is what an Alabama investor pays in 2026 for long-term gains:

The NIIT (Net Investment Income Tax) adds an extra 3.8% for taxpayers whose MAGI exceeds $200,000 (single) or $250,000 (married filing jointly). It is a federal tax only — Alabama does not have an equivalent.

Detailed Alabama capital gains tax rules

Tax history and legal basis

Alabama has taxed capital gains as ordinary income since its modern income tax was established in 1933.

Exemptions and special treatment

Alabama allows a federal income tax deduction on state returns (one of few states that does), which effectively reduces the state tax on capital gains. There is no separate capital gains exclusion.

Filing requirements

File Form 40 (resident) or 40NR (non-resident). Capital gains are reported on Schedule D and flow to your Alabama return. The filing deadline matches the federal April 15 deadline.

Recent changes and legislative updates

Alabama reduced its top marginal rate from 5% to 5% flat for most filers in recent years. The state continues to allow federal tax paid as a deduction, making effective rates lower than the statutory rate.

Worked example: $50,000 capital gain in Alabama

Here's exactly what an Alabama resident would owe on a $50,000 long-term capital gain with $80,000 in other income (single filer, 2026):

ComponentAmountNotes
Capital gain$50,000Long-term (held over 1 year)
Federal tax (15%)−$7,500Based on $80,000 ordinary income + gain
Alabama state tax (5%)−$2,500Applied to the full gain amount
Total tax owed−$10,000Federal + state combined
You keep$40,00080.0% of your gain

After both federal and Alabama state tax, you keep $40,000 of your original $50,000 gain. The effective combined rate is 20.0%.

Frequently asked questions — Alabama

Does Alabama tax short-term and long-term gains differently?

No — Alabama taxes both short-term and long-term capital gains as ordinary income at the same rates as wages. There is no state-level preferential rate for patience. The federal system, however, taxes long-term gains at 0/15/20% vs. up to 37% for short-term — a significant difference that applies regardless of state.

Do I need to file an Alabama tax return if I only have capital gains?

If you have capital gains income and meet Alabama's filing threshold, you are required to file an Alabama state income tax return. The threshold is typically similar to the standard deduction amount — check the AL Department of Revenue for the current year's filing requirements.

What if I moved to Alabama mid-year?

If you moved to Alabama during the year, you are a part-year resident. Alabama generally taxes capital gains realized while you were an Alabama resident. Gains realized before you moved may be taxable by your prior state. Keep detailed records of when each sale occurred relative to your move date.
