Mississippi Tax on Capital Gains 2026 – Mississippi taxes capital gains as ordinary income with no separate long-term or short-term rates at the state level. For tax year 2026, the state applies a flat 4% rate on taxable income above the first $10,000. This represents a reduction from the 4.4% rate in 2025 as part of Mississippi’s ongoing income tax phase-down.
Federal long-term capital gains rates (0%, 15%, or 20%) still apply separately. Residents and investors in Mississippi should understand both state and federal rules to accurately calculate their total tax liability on asset sales in 2026.
Mississippi Capital Gains Tax Rates for 2026
Mississippi uses a simple structure for individual income tax, including capital gains:
- 0% on the first $10,000 of taxable income.
- 4% on all taxable income above $10,000.
This rate applies uniformly to short-term and long-term capital gains, ordinary income, and other taxable income. There are no special state-level preferential rates for long-term holdings.
For married filing jointly or combined returns, each spouse’s tax is calculated separately and then combined. The $10,000 threshold is per return (or effectively per spouse in some cases). Personal exemptions further reduce taxable income: $6,000 for single filers, $12,000 for married filing jointly, plus additional amounts for dependents, age 65+, or blindness.
Note: No local or city income taxes apply to capital gains in Mississippi.
How Capital Gains Are Taxed in Mississippi in 2026?
Mississippi follows federal rules for computing capital gains and losses (using IRS Schedule D) but taxes the net gain as ordinary income at the state rate above.
- Short-term capital gains (assets held one year or less) → taxed at the 4% state rate (after the $10,000 threshold).
- Long-term capital gains (assets held more than one year) → also taxed at the 4% state rate with no preferential treatment.
Capital losses offset gains in the same year. Net capital losses are limited to $3,000 per year against ordinary income (consistent with federal rules), with carryover allowed.
All realized capital gains must be reported on your Mississippi return unless specifically exempted.
Special Exemptions for Capital Gains in Mississippi
Mississippi offers targeted exemptions that can eliminate state tax on certain long-term gains:
- Gains from the sale of authorized shares in financial institutions domiciled in Mississippi.
- Gains from the sale of interests in domestic corporations, domestic limited partnerships, or domestic limited liability companies held for more than one year.
Important: Any exempt gain must first be reduced by capital losses from the current year or from the two years before or after the gain.
These exemptions do not apply to federal capital gains tax. Consult a tax professional to verify eligibility, as specific definitions of “domestic” entities and “authorized shares” are governed by Mississippi Code Ann. § 27-7-9.
Federal vs. Mississippi Capital Gains Tax: Side-by-Side Comparison
| Aspect | Federal (2026) | Mississippi (2026) |
|---|---|---|
| Long-term rates | 0%, 15%, or 20% (income-based brackets) | 4% (flat on income > $10,000) |
| Short-term rates | Ordinary income rates (up to 37%) | Same as ordinary income (4%) |
| Separate rate for LTCG | Yes | No |
| Exemptions | Limited (e.g., primary residence) | Specific domestic entity gains |
| Net investment income tax | 3.8% on high earners | None |
Your total effective rate on long-term capital gains in Mississippi can be as low as the federal rate plus 4% state tax (minus any exemptions). High-income filers may also face the federal 3.8% Net Investment Income Tax.
How to Calculate Your 2026 Mississippi Capital Gains Tax (Step-by-Step)?
- Compute your federal capital gain/loss using IRS Schedule D.
- Report the Mississippi-source portion on Form 80-105 (residents) or 80-205 (nonresidents/part-year residents).
- Apply any qualifying state exemptions and offset with losses.
- Add net taxable capital gains to your other Mississippi taxable income.
- Subtract personal exemptions and standard/itemized deductions.
- Apply the state tax: 0% on first $10,000 + 4% on the rest.
Example: A single filer with $50,000 long-term capital gain and no other income (after $6,000 exemption) would have approximately $34,000 taxable income → roughly $960 in Mississippi state tax (4% of $24,000).
Recent Changes Affecting Capital Gains Tax in 2026
Mississippi continues its multi-year income tax reduction plan. The top rate drops from 4.4% in 2025 to 4% in 2026, with further scheduled reductions to 3.75% in 2027 and lower in subsequent years (subject to revenue triggers).
This phase-down directly lowers the state tax bite on capital gains for 2026 asset sales. No other major capital-gains-specific changes were enacted for 2026.
Strategies to Minimize Mississippi Capital Gains Tax in 2026
- Hold assets longer than one year (federal benefit + qualifies for state domestic-entity exemptions where applicable).
- Harvest capital losses to offset gains.
- Utilize 1031 exchanges for real estate (defers federal and state tax).
- Time sales around the $10,000 threshold or personal exemptions.
- Consider retirement accounts (e.g., IRAs) where gains grow tax-deferred.
- Relocate strategically (though Mississippi’s low rate is already competitive).
Always document holding periods and basis carefully for both federal and state audits.
