US Sales Tax Rates by State

Also searched as: sales tax calculator | tax calculator online free | add sales tax calculator | sales tax by state calculator Optimized for US users with American units and terminology.

Sales tax in the US is set at the state level, with some states also allowing local jurisdictions to add additional tax. Five states have no sales tax: Oregon, Montana, New Hampshire, Delaware, and Alaska (though Alaska allows local taxes). The highest combined state and average local rates are in Tennessee, Louisiana, and Arkansas.

How to Calculate Sales Tax

Tax Amount = Price × (Tax Rate ÷ 100). Total = Price + Tax. To find the pre-tax price from a total: Pre-Tax = Total ÷ (1 + Tax Rate ÷ 100). This reverse calculation is useful for expense reports or when you've paid an all-in price and need to know the taxable amount.
