About Sales tax calculator
American shelf prices leave the tax off, so the number you pay at the register is the price plus a sales tax that depends on where you buy. This calculator starts from the state rate for all 50 states and Washington, D.C., taken from the Tax Foundation's table as of 1 July 2026, and adds the local rate you type for your city, county or special district. It then shows the tax, the total and the combined rate, or works backwards from a receipt total to the price before tax.
The combined rate at a store is the honest weak point of every sales tax calculator: local rates change street by street, and one ZIP code can include several cities and districts with different rates. This page doesn't look up addresses or ZIP codes and never claims to. For each state it offers the average local rate as a starting point, clearly labelled as an average, and the exact figure is on a receipt or in your state revenue department's rate lookup.
Five states charge no statewide sales tax — Alaska, Delaware, Montana, New Hampshire and Oregon — though Alaska's towns and some Montana resort areas levy their own. Groceries, clothing and prescriptions are exempt or taxed at a lower rate in many states, so in the Invoice lines view each item can be marked as taxable or not taxed, and the receipt is totalled the way a register does it.
The calculator doesn't cover use tax, hotel and rental car surcharges, or seller registration and filing.
Privacy
Prices, rates and receipt lines are added up by the page in your browser; the state table is built into the page, so nothing you type is sent off to look up a rate. Recent inputs are remembered in this browser's local storage, and the price, state and local rate are kept in the page address so a copied link reopens them.
