Louisiana tax rules to know
Key points from our 2026 Louisiana data, compiled from the official sources listed at the end of this page:
- Flat 3% rate since 2025 (Act 11 of the 2024 Third Extraordinary Session), replacing the old 1.85%/3.5%/4.25% brackets.
- The standard deduction replaced the personal and dependent exemptions. It is CPI-U indexed from $12,500 / $25,000 (2025). The 2026 figures here ($12,875 single/MFS; $25,750 joint, head of household and surviving spouse) come from LDR's 2026 withholding tables and IT-540ESi. LDR says the final 2026 amounts may differ slightly after the calendar-2025 CPI-U data.
- Taxpayers 65+ can exclude up to $12,000 of retirement income each. That amount became CPI-U indexed from January 1, 2026, so the 2026 figure is slightly higher. Social Security is exempt.
Local income tax: none. Cities and counties in Louisiana do not levy their own income tax in our 2026 data.
