About Sales Tax in the United States
Sales tax in the United States is not collected at the federal level. Instead, each state sets its own base rate, and many counties, cities, and special districts add extra percentages on top. This means the actual rate varies depending on your ZIP code.
The nationwide average sales tax is about 7%. Some states, like Oregon and Delaware, have no sales tax at all, while others, like California and Tennessee, have higher rates. Use the calculator above to estimate your total cost including sales tax.
