Common questions
Sales tax, in plain terms
Which state has the highest sales tax?
Of the states covered here, California has the highest state-level rate at 7.25%, and Wyoming the lowest at 4%. State rates are only half the story though — local rates are added on top almost everywhere, and a low-rate state with high local taxes can cost more at the register than a high-rate one.
Why does the rate on my receipt not match the state rate?
Because a US sales tax bill is usually two or three taxes stacked: the state rate, then a county rate, a city rate and sometimes a special district. There are roughly 13,000 of these local jurisdictions and they change on their own schedules, so this calculator asks you for your local rate rather than guessing at it.
How do I calculate sales tax backwards from a total?
Divide the total by one plus the rate — a $107 total at 7% is $100 before tax, not $99.51. Taking 7% off the total is the common mistake, and it gets bigger as the rate does. Switch the calculator to "Take tax out of a total" and it does this for you.
Which states are covered?
8 so far: California, Tennessee, Washington, Texas, Florida, North Carolina, Wyoming, South Dakota. More are added one at a time, because every rate here is read from the state's own revenue department or statute before it goes on the page — a rate that is wrong is worse than one that is missing.
