US sales tax is local
Unlike most countries, the US has no national sales tax. Instead, 45 states plus DC charge a state sales tax, and thousands of cities and counties add local taxes on top. The result is a combined rate that varies not just by state but by zip code.
The no-sales-tax states
Five states charge no statewide sales tax: Alaska, Delaware, Montana, New Hampshire and Oregon (though Alaska allows local sales taxes). For those, this calculator shows $0 unless you enter a custom local rate.
Why use a custom rate
Because local taxes vary so much, the state averages here are a guide. If you know your exact local rate β from a receipt or your city's website β enter it in the override field for a precise figure.
Reverse calculation
Choose "Remove tax" to find the pre-tax price from a total that already includes sales tax β handy for bookkeeping and expense reports.
