Louisiana overhauled its tax system effective 2025, replacing the old three-bracket income tax with a flat rate and broadening the sales tax base. The new flat income tax rate of ~3.00% is one of the lowest among income-tax states. However, combined state and local sales taxes remain among the highest in the country, and local tax administration is notoriously complex, with individual parishes and municipalities managing their own systems.
Louisiana Income Tax Rates (2026)
Louisiana enacted comprehensive tax reform (HB 1, 2024 special session) that replaced the old progressive system:
| Tax Rate | Taxable Income Range |
|---|---|
| ~3.00% | All taxable income (flat rate) |
Previously, Louisiana had three brackets at 1.85%, 3.50%, and 4.25%. The new flat 3.00% rate took effect in 2025.
Louisiana’s standard deduction is built into the personal exemption system. The combined personal exemption and standard deduction equivalent is approximately ~$12,500 for single filers and ~$25,000 for married filing jointly under the reformed code.
Federal tax deduction: Under the old system, Louisiana allowed a deduction for federal income taxes paid. The 2024 reform eliminated or significantly modified this deduction as part of the overall rate reduction.
Sales Tax
| Component | Rate |
|---|---|
| State base rate | ~5.00% |
| Average combined (state + local) | ~9.55% |
| Highest combined rate | ~12.95% |
Louisiana has one of the highest average combined sales tax rates in the nation. The state rate was reduced from 4.45% and restructured under the 2024 reform (broadening the base while adjusting the rate). Local sales taxes are levied by parishes, municipalities, school boards, and special districts independently.
Tax complexity: Louisiana’s local sales tax system is among the most complex in the country. The Louisiana Sales and Use Tax Commission for Remote Sellers provides a single point of filing for remote sellers, but brick-and-mortar businesses must navigate parish-by-parish rules.
Exempt from sales tax: Prescription medications. Under the reform, many previously exempt goods and services were brought into the sales tax base, though groceries remain exempt from the state portion.
Property Tax
| Metric | Amount |
|---|---|
| Average effective rate | ~0.56% |
| National average | 0.99% |
Louisiana property taxes are well below the national average. Assessment ratios and millage rates vary by parish.
Assessment ratios:
- Residential: 10% of fair market value
- Commercial/industrial: 15% of fair market value
- Land: 10% of use value
Homestead exemption: The first ~$75,000 of a home’s assessed value (equivalent to ~$7,500 of assessed value at the 10% ratio) is exempt from parish and municipal property taxes (but not all special district millages).
Example: A home with a fair market value of $250,000, assessed at 10% = $25,000. After the $7,500 homestead exemption, the taxable value is $17,500. At a typical combined millage of ~100 mills, annual property tax is approximately ~$1,750.
Other Taxes
- Estate and inheritance tax: Louisiana does not impose a state estate tax or inheritance tax.
- Capital gains: Taxed at the flat ~3.00% income tax rate under the new system.
- Fuel tax: ~$0.20 per gallon — among the lowest in the nation.
- Cigarette tax: ~$1.08 per pack.
- Severance tax: Louisiana imposes severance taxes on oil (
12.50% of value), natural gas ($0.158 per MCF), and timber. This is a significant revenue source given the state’s energy industry. - Local occupational license taxes: Parishes and municipalities may impose license taxes on businesses.
- Franchise tax: The corporate franchise tax was repealed as part of the 2024 tax reform package.
Tax Breaks and Credits
- No Social Security tax: Louisiana does not tax Social Security benefits.
- Retirement income: Under the reformed system, the first ~$6,000 of retirement income from pensions, annuities, and other qualifying sources per person remains exempt. Federal, state, and military retirement may have additional exclusions.
- Homestead exemption: The ~$75,000 homestead exemption is automatic for owner-occupied homes and provides substantial property tax relief.
- School readiness tax credits: Credits for businesses and individuals supporting quality childcare (participation in the state’s quality rating system).
- Louisiana EITC: ~5% of the federal Earned Income Tax Credit (refundable).
- Historic preservation credit: 25% of qualifying rehabilitation expenses for state-registered historic structures.
- Motion picture investor credit: Louisiana’s film tax credit program (20%–25% of qualifying production expenses) has made the state a major film production hub.
- 529 plan deduction: Up to
$2,400 per beneficiary per year ($4,800 for married filing jointly).
