The sales tax calculator makes it easy to find the tax on any purchase in any US state. Simply enter your purchase price and state to get an instant result.
Understanding State vs Local Sales Tax
Most purchases are subject to both a state sales tax and local sales taxes (county and city). This calculator shows the state rate — your actual rate will be higher if your location has local taxes. For example, Tennessee has a 7% state rate, but with local taxes, the average total rate is about 9.5%.
States with No Sales Tax
Five states have no state sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon. If you shop in these states, you'll typically pay no sales tax (though some Alaska localities do charge local sales tax).
Online Shopping and Sales Tax
Following the 2018 Supreme Court ruling in South Dakota v. Wayfair, states can require online sellers to collect sales tax even without a physical presence. Major retailers like Amazon now collect sales tax in all states that have it, so you'll pay the same rate shopping online as in-store.
