Louisiana's state sales tax rate is 4.45%. Cities and counties can add local taxes on top. The average combined rate across Louisiana is 10.01%.

What's Taxable for Restaurants & Food Businesses
Vendor Discount
Louisiana offers a vendor discount
1.1% of tax due (vendor compensation) if filed and paid on time
This is money back in your pocket for filing on time. TaxAside files on time, every time — so you capture this discount automatically.
Penalties for Late Filing
Late Filing Penalty
5% per month, max 25% of tax due
Interest
0.5% per month on unpaid tax
Miss a deadline and Louisianastarts charging penalties and interest immediately. That adds up fast on a busy restaurant's tax bill.
