Common mistakes to avoid

Using only the state rate

Louisiana's 4.45% state rate is only the starting point. New Orleans is 9.45% combined.

Subtracting tax from a gross total

To reverse sales tax, divide by 1 + (rate ÷ 100). Do not subtract the percentage from the tax-inclusive price.

Treating groceries and clothing the same

Exemptions differ by item. Review Louisiana rules for food, apparel, medicine, and digital goods before invoicing.

Quoting the average rate for every address

The 9.56% average is useful for estimates; use address-level rates for compliance and customer quotes.
