Louisiana Tax on Capital Gains 2026 – Louisiana taxes capital gains as ordinary income at the state level. For tax year 2026, the state applies a flat 3% rate with no distinction between short-term and long-term gains. This guide explains everything U.S. taxpayers—especially Louisiana residents, part-year residents, and non-residents with Louisiana-source income—need to know about the Louisiana tax on capital gains in 2026, including how it interacts with federal taxes and recent law changes.
Louisiana Capital Gains Tax Rate 2026
Louisiana uses a flat 3% individual income tax rate on all taxable income, including capital gains, for taxable periods beginning on or after January 1, 2025. This rate remains in effect for 2026 with no scheduled changes for individuals.
Unlike the federal system, Louisiana does not offer preferential rates for long-term capital gains. All realized gains—whether from stocks, real estate, cryptocurrencies, or business assets—are taxed at the same 3% flat rate once included in Louisiana taxable income.
There are no local income taxes in Louisiana, so the state rate is the only additional layer beyond federal taxes.
How Louisiana Taxes Short-Term vs. Long-Term Capital Gains?
Louisiana treats short-term and long-term capital gains identically for state tax purposes. Both are included in federal adjusted gross income (AGI) and flow through to Louisiana taxable income, where the flat 3% rate applies.
- Short-term gains (assets held one year or less): Taxed at ordinary federal income rates (up to 37%) plus the 3% Louisiana rate.
- Long-term gains (assets held more than one year): Eligible for federal preferential rates of 0%, 15%, or 20%, plus the 3% Louisiana rate.
This structure makes Louisiana relatively taxpayer-friendly compared to states with higher top rates, but the lack of a state-level long-term preference means holding periods matter more for your federal bill than your state bill.
Federal Capital Gains Tax Rates for 2026 and Interaction with Louisiana
Federal long-term capital gains rates for 2026 remain 0%, 15%, and 20%, with income thresholds adjusted for inflation:
| Filing Status | 0% Rate (Taxable Income) | 15% Rate (Taxable Income) | 20% Rate (Taxable Income) |
|---|---|---|---|
| Single | $0 – $49,450 | $49,451 – $545,500 | Over $545,500 |
| Married Filing Jointly | $0 – $98,900 | $98,901 – $613,700 | Over $613,700 |
Short-term gains and ordinary income follow the regular federal brackets (up to 37%). High earners may also owe the 3.8% Net Investment Income Tax (NIIT).
Louisiana starts its calculation with your federal AGI (which already includes all capital gains). You then make Louisiana-specific additions and subtractions to arrive at Louisiana taxable income, which is taxed at 3%.
Major Changes to Louisiana Capital Gains Tax Effective 2025–2026
The most significant recent change is the full repeal of the net capital gains deduction for sales or exchanges occurring on or after January 1, 2025. Previously, Louisiana residents could deduct up to 100% of net capital gains from the sale of certain non-publicly traded Louisiana-domiciled businesses (if held for five or more years). This deduction is no longer available for 2025 and later tax years, including 2026.
The state also completed its shift to a flat 3% individual income tax rate in 2025 (replacing the prior graduated brackets), which applies fully to 2026 capital gains.
How to Calculate Louisiana Tax on Capital Gains in 2026?
- Report all capital gains on your federal Form 1040/Schedule D.
- Use federal AGI as the starting point for Louisiana Form IT-540 (Resident) or IT-540B (Nonresident/Part-Year).
- Apply Louisiana additions and subtractions (e.g., add back certain interest/dividends if applicable; subtract qualifying retirement income).
- Multiply Louisiana taxable income by the flat 3% rate.
Louisiana does not require a separate capital gains worksheet for most filers in 2026, as the flat rate simplifies calculations.
Exemptions, Deductions, and Credits Related to Capital Gains
Louisiana offers standard personal exemptions and deductions that reduce overall taxable income (and thus the tax on capital gains). Qualifying retirement income, Social Security, and certain other items remain exempt or deductible. However, the former business net capital gains deduction no longer applies.
No special capital gains exemptions exist beyond these general provisions.
Reporting Capital Gains on Your Louisiana Tax Return
- Residents: File Form IT-540 and report all capital gains.
- Non-residents and part-year residents: File Form IT-540B and report only Louisiana-source capital gains (e.g., from Louisiana real estate or business interests).
- Deadline: May 15, 2027, for 2026 tax year returns (with automatic six-month filing extension to November 15, 2027). Payment is still due by the original deadline.

Strategies to Minimize Louisiana Tax on Capital Gains in 2026
- Hold assets longer than one year to qualify for lower federal long-term rates.
- Use tax-loss harvesting to offset gains.
- Consider 1031 exchanges for real estate to defer gains (federal and state rules align on deferral).
- Time large sales around other income to manage overall brackets.
- Maximize Louisiana retirement income deductions and exemptions.
Consult a tax professional for personalized planning, especially with federal NIIT or large business sales.
Louisiana Capital Gains Tax for Non-Residents
Non-residents pay Louisiana tax only on capital gains from Louisiana sources, such as the sale of Louisiana real property or interests in Louisiana-based businesses. The same 3% flat rate applies.
