Alabama Capital Gains Tax Rate (2026)
Alabama capital gains tax overview
Three brackets: 2% up to $500 (single), 4% up to $3,000, 5% above.
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:
| Federal Long-Term Rate | Alabama State Rate | Combined Rate | Plus NIIT (if applicable) |
|---|---|---|---|
| 0% | 5% | 5% | 8.8% |
| 15% | 5% | 20% | 23.8% |
| 20% | 5% | 25% | 28.8% |
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.
How Alabama compares to other states
Alabama's top rate of 5% places it in the lower-middle tier of state capital gains taxation. For comparison:
- Zero-tax states (FL, TX, NV, etc.): 0% — total with 15% federal = 15%
- Low-rate states (AZ, IN, PA): 2.5–3.1% — total with 15% federal = 17.5–18.1%
- Alabama: 5% — total with 15% federal = 20.0%
- High-rate states (NY, NJ): 10.75–10.9% — total with 15% federal = ~26%
- California: 13.3% — total with 15% federal = 28.3%
Tax-reduction strategies for Alabama residents
With a top state rate of 5%, minimizing capital gains tax is particularly important in Alabama. Key strategies:
- Hold over 1 year for long-term federal rates (0/15/20%). Alabama does not offer a preferential state rate, but federal savings alone are often 7–17%.
- Tax-loss harvesting: Offset your gains with losses realized in the same year. A $20,000 loss offsets $20,000 of gains dollar-for-dollar, saving up to 25% ($5,000) on that $20,000 at top rates.
- 0% bracket planning: In lower-income years (retirement, sabbatical, between jobs), realize gains at the federal 0% rate. You still owe Alabama state tax, but eliminating the federal component is significant.
- Donate appreciated stock directly to charity or a donor-advised fund to avoid capital gains tax entirely while generating a charitable deduction for the full fair market value.
- Installment sales: If selling a business or real estate, structuring as an installment sale spreads the gain over multiple years, potentially keeping each year's gain in a lower bracket.
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):
| Component | Amount | Notes |
|---|---|---|
| Capital gain | $50,000 | Long-term (held over 1 year) |
| Federal tax (15%) | −$7,500 | Based on $80,000 ordinary income + gain |
| Alabama state tax (5%) | −$2,500 | Applied to the full gain amount |
| Total tax owed | −$10,000 | Federal + state combined |
| You keep | $40,000 | 80.0% 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.
