    This is the state rate plus the population-weighted average local rate. Your actual rate depends on the specific address — city and special-district taxes vary within every state. Before collecting tax from customers, verify the exact rate for the delivery address with the state’s Department of Revenue or an address-level lookup.

    How this works

    State, local, and combined — and why your address matters

    Sales tax in the United States is not one tax but a stack of them. Most states set a statewide rate, then allow counties, cities, and special districts to add their own on top. What you actually pay at the register is the combined rate for that specific location — which is why the same purchase can cost more in a city centre than in a suburb ten minutes away.

    This calculator shows the state rate plus the population-weighted average local rate. That average is genuinely useful for a quick estimate and for comparing states, but it is not the rate for any one address. Louisiana tops the table at over 10% combined, while Delaware, Montana, New Hampshire and Oregon charge nothing at all. Alaska is the odd one out: no state sales tax, but local taxes that in some towns climb higher than several states' combined rates.

    The gap between the average and a real address is exactly where sales tax gets people into trouble. If you're a shopper, the average is close enough to budget with. If you collect sales tax from customers — an online seller, a service business, anyone with nexus in a state — you are responsible for charging the correct rate for each customer's address, and the state average will not satisfy an auditor. For that you need an address-level lookup, which every state Department of Revenue provides.

    A few wrinkles the headline rate hides: groceries, clothing, and prescriptions are exempt or reduced-rate in many states, so the general rate here won't apply to every basket. California, Utah, and Virginia bake a mandatory local add-on into their state figure. And New Jersey's average dips slightly below its state rate because Urban Enterprise Zones charge half rate in designated areas. The per-state pages spell out each of these where they apply.

    Working out what your business owes across multiple states is its own project — see our state income tax calculator for the income side, or book a free consultation about sales-tax nexus and registration.

    Questions

    Sales tax, answered

    Five states levy no sales tax at any level: Delaware, Montana, New Hampshire and Oregon have neither a state nor a local sales tax. Alaska has no statewide sales tax, but many Alaskan localities levy their own, so you may still pay sales tax on a purchase there. Everywhere else charges a state sales tax, and most add local taxes on top.

    Louisiana has the highest average combined rate at 10.13% — a 5.00% state rate plus about 5.13% in average local taxes. Tennessee, Arkansas, Washington and Louisiana all cluster near the top; the specific ranking shifts as local rates change.

    Because it is a state average, not an address-level rate. Sales tax is set by the delivery address, and cities, counties, and special districts within a state can charge more or less than the statewide average. A downtown address and a suburb in the same state often differ. Use this for a close estimate, then confirm the exact rate for your address.

    Every state Department of Revenue publishes an address-level rate lookup, which is the authoritative source for what to charge. Several paid services also return address-accurate rates via an API if you need to automate it for a store. This tool intentionally shows the state average rather than guessing at a city rate free data cannot verify.

    Switch to “Find the pre-tax price” and enter a total you already paid. The tool works backwards from the combined rate to split that total into the original price and the sales tax inside it — useful for expense records and bookkeeping when a receipt only shows the total.
