How does US sales tax work?

Unlike UK VAT which is a single nationwide rate, US sales tax varies by state — and within states can vary further by county and city. This calculator uses the combined state rate. Always check your local county and city rates for precise calculations on large purchases.

Which states have no sales tax?: Five states have no state sales tax: Oregon, Montana, New Hampshire, Delaware and Alaska. However, some local jurisdictions in Alaska do levy a sales tax even though the state does not.
Is sales tax included in the price in the US?: Unlike in the UK where VAT is included in the displayed price, US prices are typically shown before sales tax. Tax is added at the register when you pay. This is why the final price you pay is always higher than the shelf price.
What is the difference between US sales tax and UK VAT?: UK VAT is a single national rate (20%) included in all displayed prices. US sales tax varies by state, county and city, is not included in shelf prices, and ranges from 0% to over 10% depending on location.
Why does sales tax vary so much between states?: Sales tax in the United States is set at state level, not federally. Each state sets its own base rate, and many states allow counties and cities to add local taxes on top. This is why the combined rate (state plus local) in places like Louisiana or Tennessee can exceed 9%, while states like Oregon and Delaware have no sales tax at all.
Are groceries taxed in the US?: It depends on the state. Some states (like California, Texas, and New York) exempt most grocery items from sales tax. Others (like Mississippi and Alabama) tax groceries at the full rate. Prepared food — such as restaurant meals or ready-to-eat items — is taxable in most states even where groceries are exempt.
Do online purchases in the US have sales tax?: Yes, in most cases. Following the 2018 Supreme Court ruling in South Dakota v. Wayfair, states can require online retailers to collect sales tax even if the retailer has no physical presence in that state. Most major online retailers now collect and remit sales tax for all US states.
