Sales tax combines state and local rates. Five states (Oregon, Montana, New Hampshire, Delaware, Alaska) have no state sales tax. California has the highest state rate at 7.25%, but combined local rates in some areas push the total above 10%. Always check combined rates, as local taxes add 1-4% on top of state rates.
