How Sales Tax Works

Sales tax in the United States is charged at the point of sale on most goods and some services. Unlike VAT systems used in other countries, US sales tax is only collected at the final retail sale — not at each stage of production.

Rates vary significantly by state, ranging from 0% in states like Oregon and Delaware to 7.25% in California (state rate only). When local taxes are added, combined rates can exceed 10% in some cities.
