How much is sales tax in Louisiana?
Louisiana's base rate is 5%, but local parishes and municipalities add significantly more, creating combined rates anywhere from 5% to 12.95%. The average across Louisiana's 749 taxing jurisdictions is 9.89%, and Saint Joseph reaches the highest at 12.95%. Some rural parishes stay close to the 5% minimum, while urban and industrial areas climb much higher.
The gap between the lowest and highest rate in Louisiana is nearly 8 percentage points—massive. A customer in one parish might owe 5%, while another customer just a few miles away in a different parish could owe 11% or 12%. This variation means you must always verify by address; geographic guessing will cost you money.
What's taxed and what's exempt in Louisiana
Groceries are exempt from Louisiana sales tax, helping families afford food. Clothing purchases are taxable at the combined rate.
SaaS and software subscriptions are taxable in Louisiana, so digital products and cloud services incur sales tax. Prescription medicines are exempt. Restaurant meals and prepared foods are taxable.
Do you have to collect Louisiana sales tax? (Economic nexus)
Like most states after the 2018 Wayfair decision, Louisiana requires out-of-state sellers to register and collect once their sales into the state cross an economic-nexus threshold. That line is commonly around $100,000 of sales into Louisiana per year, and some states also count a number of separate transactions — but the exact figure, and whether the transaction count still applies, change from time to time. Confirm Louisiana's current threshold before you rely on it.
If you sell into Louisiana from out of state, the practical question is whether you've crossed that line. Watching your sales into each state is how you know when you're on the hook — and it's the kind of thing that's easy to miss until a notice shows up.

How to calculate Louisiana sales tax
The math itself is simple: multiply the taxable price by the combined rate for the buyer's location. A $100 order at 9.89% means about $9.89 in tax. The hard part is getting the right rate for every address, keeping it current as rates change, and doing it fast enough to run inside a checkout.
