What Is Sales Tax?

Sales tax is a consumption tax imposed by governments on the sale of goods and services. In the United States, sales tax rates vary by state, county, and city, resulting in over 11,000 different tax jurisdictions. Unlike VAT, sales tax is only collected at the final point of sale to the consumer, not at each stage of production.

US sales tax rates range from 0% (Oregon, Montana) to over 10% in some localities
Five US states have no state sales tax: Alaska, Delaware, Montana, New Hampshire, Oregon
Sales tax is calculated on the pre-tax price: Tax = Price x Rate
Many states exempt groceries, prescription drugs, and clothing from sales tax

Knowing how to calculate sales tax helps you budget accurately and understand the true cost of purchases before you reach the checkout.
