State plus local sales tax
The United States has no national sales tax. Forty-five states and the District of Columbia charge a statewide sales tax, listed below as of January 1, 2026, and most also let cities, counties and special districts add local rates. Choose your state, then enter your local rate to match the combined rate on a receipt.
Alaska, Delaware, Montana, New Hampshire and Oregon have no statewide sales tax, though some Alaska localities charge one. Some items, such as groceries or prescription drugs, are taxed at a lower rate or exempt in many states; choose Custom rate when an item is taxed differently.
Add tax or find the pre-tax price
To add sales tax, enter the price before tax: $100 at a combined 8.25% becomes $108.25. To work backwards from a total, choose Price includes tax and enter the total. Results are rounded to the nearest cent, as most registers do.
Rates change, and your state revenue department publishes the official current rate for an address. This calculator does arithmetic only and is not tax advice.
