Find your combined rate
US sales tax is set by the state plus counties and cities: for example California 7.25% state rate, plus your city or county. The combined rate can be over 10% in some cities. Your state’s Department of Revenue website has a rate lookup by address.

- Online sellers usually charge tax based on the delivery address.

Errors and how to fix them
