Louisiana Sales Tax Calculator 2026 – how it works
Louisiana’s State general sales and use tax applies a flat statewide rate to the taxable amount of a transaction. Under this simplified approach, the estimated tax is calculated by applying the state sales tax rate of 5.00% to the taxable sales price or taxable use amount. This content reflects the standard state-level rate only and does not address any other potential tax layers or transaction-specific rules. For official guidance and publications, refer to the Louisiana Department of Revenue (https://revenue.louisiana.gov).
Examples
A simplified estimate applies the 5.00% state sales tax rate to the taxable amount. For example, if a transaction has a taxable amount of 100, the estimated state sales tax would be 5.00 and the total would be 105. This example illustrates the flat-rate structure at the state level and is limited to the standard statewide rate described here.
Limitations and important notes
Results are simplified estimates based only on the standard Louisiana state-level sales tax rate of 5.00%. This summary does not account for transaction-specific taxability determinations, sourcing rules, or other state-administered sales and use tax considerations that may affect whether an amount is taxable or how it is measured. It also does not represent a filing calculation or an official determination of tax due. Official rules and interpretations may differ from simplified estimates.
