About Sales Tax Calculator

Sales Tax Calculator answers two everyday questions instantly: "what will this cost with tax?" and "how much of this total was tax?" Pick your state, and the tool applies the 2026 state rate plus your state's average local rate, both of which you can override with your city's exact rate if you know it.

Built for both directions

Add mode starts from a sticker price and adds state and local tax. Reverse mode starts from a receipt total and works backwards to the pre-tax price, which is handy for expense reports, invoices, and bookkeeping.

Real 2026 rates, all 51 jurisdictions

Rates come from the Tax Foundation's July 1, 2026 midyear table: the statutory state rate plus the population-weighted average local rate for each state and DC. Special cases are handled, including the five states with no statewide sales tax, Alaska's local-only taxes, and the mandatory statewide local rates baked into California, Utah, and Virginia figures. Each state also has its own page, like the Texas sales tax calculator, with rates preloaded.

• Estimates only. Local sales tax rates vary by city, county, and district. The average local rate is a statewide average, so your register receipt may differ.
• Product rules vary. Many states exempt or discount groceries, clothing, or medicine, and some tax services differently. This tool applies one rate to the full amount.
• Rates change. Figures reflect the Tax Foundation's July 1, 2026 table. States and cities adjust rates during the year.
• No professional relationship. Using this site does not create any advisor or accountant relationship.
• No liability. We accept no liability for decisions made based on this tool's output.
