What Is Sales Tax?
Sales tax is a consumption-based tax charged on the sale of goods and services and collected by the seller at the point of purchase. Prices may be listed before tax or include tax, depending on the country or region.
Sales Tax in the United States
The U.S. has no federal sales tax. Sales tax is imposed at the state and local levels, with rates varying by state, city, and product type. Five states—Alaska, Delaware, Montana, New Hampshire, and Oregon—do not levy statewide sales tax.
How Sales Tax Rates Work
Sales tax rates typically range from 0% to over 10% when state and local taxes are combined. Certain items, such as food or prescription medicine, may be exempt depending on state law.
Sales Tax vs VAT vs GST
Sales Tax (U.S.): Applied only at the final retail sale
VAT (Value-Added Tax): Collected at each stage of production
GST (Goods and Services Tax): Similar to VAT, used in several countries
Why Sales Tax Matters
Sales tax is a major revenue source for state and local governments and directly affects consumer purchase costs and business pricing strategies.
