How Louisiana sales tax works
Louisiana charges a state sales tax of 5.00%, and most areas add a local rate on top.
The average combined rate is about 10.12%, but the exact figure depends on your county or city. 5% state rate (raised in 2025) plus very high local rates.
Sales tax is added at checkout to the price of taxable goods and some services, so the total you pay is the listed price plus the combined rate.
