Louisiana sales tax rate
Louisiana charges a statewide sales tax of 5%. Cities, counties and special districts can add their own local sales taxes on top, which brings the population-weighted average combined rate to about 10.11% in 2026. Because local rates differ from place to place, the exact rate at a given address may be higher or lower than the average.
How to calculate Louisiana sales tax
Multiply the price by the rate: sales tax = price × rate ÷ 100, then add it to the price for the total. For a $100 purchase at the combined 10.11% rate, the tax is $10.11 and the total is $110.11. Use the calculator above for any amount, and swap in your local rate if you know it.
