Louisiana tax guide: sales, income and property tax
Three taxes decide most everyday money calculations in Louisiana: what you pay at the register, what leaves your paycheck, and what your home costs each year. This guide sets out each one with the current figures, then links to the calculators that apply them. Rates are reviewed against state sources; confirm a specific transaction with the Louisiana Department of Revenue.
The short answer
Louisiana: 5% state sales tax, about 9.56% average combined (rank 1 of 51 — 2.95 points above the 6.61% all-state average), a flat income tax, and an average effective property tax of 0.55% (rank 45 of 51). On a $100 purchase at the average combined rate, the tax is $10.
Sales tax in Louisiana
The statewide base rate is 5%. Counties, cities and special districts add their own layers, bringing the average combined rate to about 9.56% — and the rate at a specific address can sit well above or below that average. On a $100 purchase, the tax is $5 at the base rate and roughly $10 at the average combined rate. The difference is local tax, which is why two towns in the same state can charge noticeably different totals on the same item.
Groceries are exempt from the state tax; parish/local taxes on food vary.
Worked examples at the average combined rate
What the 9.56% average combined rate adds to purchases of different sizes:
| Purchase | Tax | Total |
|---|---|---|
| $25 | $2 | $27 |
| $100 | $10 | $110 |
| $500 | $48 | $548 |
| $1,000 | $96 | $1,096 |
| $10,000 | $956 | $10,956 |
If you sell into Louisiana from another state, economic nexus rules can oblige you to collect its tax once your sales pass the state's threshold — the exact threshold and what counts toward it are in the Louisiana sales tax calculator and rate page, and the data hub for the state is the Louisiana locations page.
Income tax in Louisiana
Louisiana taxes income at a single flat rate. Moved to a flat 3% income tax in 2025, paired with the state sales tax rising to 5%. A flat structure makes take-home pay easy to estimate: state tax is close to a fixed share of taxable income, after the state's own deductions and exemptions.
Federal tax applies the same everywhere; the state layer is what changes a paycheck between two states. Run the same salary through the paycheck calculator and the take-home pay calculator with and without a state rate to see the size of the difference before negotiating a move or a remote-work arrangement.
Property tax in Louisiana
The average effective property tax rate in Louisiana is about 0.55% of a home's value per year. On a $400,000 home that is roughly $2,200 a year, or $183 a month — a real line in the housing budget, collected through escrow in most mortgages. Averages hide wide local variation: the county and school district set most of the rate, and homestead exemptions can cut the taxable value for owner-occupiers.
How Louisiana compares
The states closest to Louisiana on average combined sales tax, with the national extremes for scale. The all-state averages across the 51 entries are 6.61% for combined sales tax and 1.04% for property tax.
| State | Combined sales tax | Property tax |
|---|---|---|
| Louisiana (this guide) | 9.56% | 0.55% |
| Tennessee | 9.55% | 0.67% |
| Arkansas | 9.44% | 0.62% |
| Washington | 9.38% | 0.87% |
| Alabama | 9.29% | 0.42% |
| Oregon — lowest combined | 0% | 0.82% |
What this means for your money
Property tax is light in Louisiana: an average effective rate of 0.55% ranks 45 of 51, well below the all-state average of 1.04%. A $400,000 home carries about $2,200 a year. Low property tax lowers the fixed cost of owning, which partly offsets whatever the state's income and sales taxes take.
Read together: Louisiana combines an average combined sales tax of 9.56% (rank 1 of 51), an average effective property tax of 0.55% (rank 45 of 51) and a flat state income tax. A household comparing states should compare all three against its own pattern — a high earner who rents weighs the income tax most; a homeowner on a fixed income weighs the property tax most.
