Guide
How sales tax is calculated
Tax = price × rate ÷ 100. Total = price + tax. To take tax out of a total, divide by (1 + rate ÷ 100): at 7.25%, a $107.25 total is $100.00 before tax and $7.25 tax.
Example: a $80.00 purchase in Texas at the 6.25% state rate has $5.00 tax, for $85.00.
State rate plus local rate
Sales tax in the United States is set by each state, and most states also let counties, cities and special districts add their own rate on top. This calculator uses each state’s statewide rate. Local taxes are not included yet; if you know your local rate, enter it in the local rate box and it is added to the state rate.
California, Utah and Virginia charge a mandatory statewide local add-on (1.25%, 1.25% and 1%). It applies everywhere in those states, so it is included in the rate shown, following the Tax Foundation’s method.
States with no statewide sales tax
Alaska, Delaware, Montana, New Hampshire and Oregon have no statewide sales tax. Alaska lets local governments charge one, and some Montana resort areas charge a local resort tax.
Common questions
Why is my receipt different from the calculator?
Usually because of local taxes, which are added to the state rate, or because some items (often groceries or prescription medicine) are taxed at a lower rate or not at all in your state.
Do online orders charge sales tax?
Most large online sellers now collect sales tax based on the delivery address, at the state and local rate for that address.
