The nation's highest combined rate, built on local taxes
Louisiana's 5% statewide rate is modest, but parish and city taxes are the heaviest in the country, producing the nation's highest average combined rate at 10.11% — an average local add-on above 5 percentage points. More than half of what a typical Louisiana shopper pays comes from local taxes, not the state.
Because parishes and cities set their own rates and bases, two neighboring parishes can charge very different totals, so the 5% pre-fill is far below the real combined figure. Enter your parish and city's combined rate; some items may be taxed differently. This is an estimate, not tax advice.
