Free USA Sales Tax Calculator — State + Local Combined Rates

Sales tax in the United States is not uniform — it varies dramatically depending on the state, county, and even city where the purchase is made. While 5 states (Alaska, Delaware, Montana, New Hampshire, and Oregon) impose no statewide sales tax, the remaining 45 states charge rates ranging from 2.9% (Colorado) to 7.25% (California). On top of state rates, thousands of local jurisdictions — counties, cities, and special taxing districts — add their own surcharges. The combined rate in some areas of Louisiana and Tennessee exceeds 10%. This free USA Sales Tax Calculator helps Americans, tourists, and businesses accurately compute the total sales tax on any purchase amount using combined state and local rates, ensuring full compliance with United States tax regulations.

🇺🇸 How USA Sales Tax Works

Unlike Value Added Tax (VAT) used in most countries, USA sales tax is a single-stage tax collected only at the point of final sale to the consumer. It is NOT included in the listed price — Americans see the pre-tax price on the shelf and the tax is added at checkout. Businesses collect sales tax on behalf of the state and remit it to the appropriate taxing authority. With the 2018 South Dakota v. Wayfair Supreme Court decision, online retailers must now also collect sales tax in states where they have 'economic nexus,' even without a physical presence.
