How Sales Tax Works
Sales tax is a percentage added to the price of goods and services. The rate varies by state and locality. To calculate: Tax = Amount × (Rate / 100), Total = Amount + Tax.
State sales tax rates range from 0% (Oregon, Montana, New Hampshire, Delaware) to over 9% (California, Tennessee, Arkansas). Many cities add local taxes on top of the state rate.
