How This Calculator Works

Our sales tax calculator combines state-level tax rates with local county and city rates to give you the exact amount of tax on any purchase. Select your state to see the state rate, then optionally choose a specific county for a more precise calculation. If you don't select a county, we use the statewide average local rate.
