Sales Tax Calculator by State

Sales Tax Calculator by State looks up the 2026 statewide base sales tax rate for any US state and instantly calculates the tax amount and total cost for a purchase. Five states — Alaska, Delaware, Montana, New Hampshire, and Oregon — charge no statewide sales tax at all. The rate shown is a floor estimate: most states allow cities and counties to add local surtax on top of the statewide rate, so the actual rate paid at checkout can be higher depending on location. This makes the tool ideal for quick budget checks, price comparisons across states, and back-of-envelope estimates before a big purchase.
