State rate versus combined rate
Louisiana sets a statewide base rate of 5%. Counties, cities and special districts in many states add their own local rates, so the rate at the register can be higher than the state rate. Always use the combined rate for the address where the sale takes place, or where the goods are delivered.

What is taxable
Most tangible goods are taxable. Groceries, prescription drugs and some clothing are exempt or taxed at a lower rate in many states, and services are taxed in some states but not others. Check the Louisiana department of revenue guidance for your product.
Sellers and nexus
Since 2018, states can require remote sellers to collect sales tax once they pass an economic nexus threshold based on sales or transactions in the state. If you sell online into Louisiana, check whether you have crossed it.
Quick reference at 5%
