Mississippi Capital Gains Tax Rate (2026)
Mississippi capital gains tax overview
Mississippi has a 4.7% flat rate (down from 5% after reforms). No preferential capital gains rate.
Federal + Mississippi combined rates
Your total capital gains tax bill includes both layers — federal and state. Here is what a Mississippi investor pays in 2026 for long-term gains:
| Federal Long-Term Rate | Mississippi State Rate | Combined Rate | Plus NIIT (if applicable) |
|---|---|---|---|
| 0% | 4.70% | 4.70% | 8.5% |
| 15% | 4.70% | 19.7% | 23.5% |
| 20% | 4.70% | 24.7% | 28.5% |
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 — Mississippi does not have an equivalent.
How Mississippi compares to other states
Mississippi's top rate of 4.70% 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%
- Mississippi: 4.70% — total with 15% federal = 19.7%
- 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 Mississippi residents
With a top state rate of 4.70%, minimizing capital gains tax is particularly important in Mississippi. Key strategies:
- Hold over 1 year for long-term federal rates (0/15/20%). Mississippi 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% ($4,940) 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 Mississippi 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 Mississippi capital gains tax rules
Tax history and legal basis
Mississippi taxes capital gains as ordinary income. The state moved to a flat rate of 4.7% effective 2026, completing a multi-year phase-out of its graduated system.
Exemptions and special treatment
Mississippi does not offer preferential capital gains rates. The state previously exempted the first $5,000 of taxable income but is phasing this out with the flat tax transition. No specific capital gains exclusions exist.
Filing requirements
File Form 80-105 (resident). Mississippi starts with federal AGI. The state requires estimated payments if owing $200+. Filing deadline is April 15.
Recent changes and legislative updates
Mississippi has been phasing toward a flat tax: from a system with rates of 0%/3%/4%/5% to a flat 4.7% by 2026. The eventual goal is to reach 4% or eliminate the income tax entirely. The first $10,000 of income is now exempt for all filers.
Worked example: $50,000 capital gain in Mississippi
Here's exactly what a Mississippi 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 |
| Mississippi state tax (4.7%) | −$2,350 | Applied to the full gain amount |
| Total tax owed | −$9,850 | Federal + state combined |
| You keep | $40,150 | 80.3% of your gain |
After both federal and Mississippi state tax, you keep $40,150 of your original $50,000 gain. The effective combined rate is 19.7%.
Frequently asked questions — Mississippi
Does Mississippi tax short-term and long-term gains differently?
No — Mississippi 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 a Mississippi tax return if I only have capital gains?
If you have capital gains income and meet Mississippi's filing threshold, you are required to file a Mississippi state income tax return. The threshold is typically similar to the standard deduction amount — check the MS Department of Revenue for the current year's filing requirements.
What if I moved to Mississippi mid-year?
If you moved to Mississippi during the year, you are a part-year resident. Mississippi generally taxes capital gains realized while you were a Mississippi 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.
