How sales tax works in Louisiana
Louisiana has a modest 4.45% state rate but the highest average combined rate in the country, because parishes and cities add large local taxes — some areas exceed 11.5%. Local jurisdictions also administer and audit their own taxes, which makes compliance unusually complex.
Rates are approximate and current as of the 2024–2025 tax years. Local rates change and vary by address; confirm the exact figure with the Louisiana department of revenue or a rate lookup by ZIP code before relying on it.
