How Sales Tax Works
Sales tax is a consumption tax imposed by state and local governments on the sale of goods and certain services. It is calculated as a percentage of the purchase price and collected by the retailer at the point of sale.
The Formula
Sales Tax = Price × (Tax Rate ÷ 100)
Total = Price + Sales TaxRates vary significantly by state — from 0% in states like Oregon, Montana, and New Hampshire, to over 7% in states like California, Tennessee, and Mississippi. Many cities and counties also add local taxes on top of the state rate.
