How Sales Tax Works in Every State (2026 Guide)

You see the price tag on a new laptop: $999. You get to the register, and the total is $1,086. That extra $87 is sales tax, and depending on where you live, it could be higher, lower, or nonexistent. Sales tax is the most common tax most Americans encounter on a daily basis, yet few people understand how it's actually calculated or why it varies so dramatically from one address to the next.

This guide breaks down exactly how sales tax works across the United States in 2026 — how rates are set, which states charge nothing at all, what gets taxed versus what doesn't, and how it all affects the real cost of everything you buy.

How Sales Tax Is Calculated

Sales tax is a consumption tax imposed by state and local governments on the sale of goods and certain services. The calculation itself is straightforward: take the price of the item and multiply it by the applicable tax rate. A $50 item at a 7% sales tax rate costs you $53.50.

What makes sales tax complicated isn't the math — it's the layering. In most states, the tax you pay at checkout is actually a combination of multiple rates stacked on top of each other:

State sales tax is the base rate set by the state legislature. This applies uniformly to all taxable purchases made anywhere within the state.

County sales tax is an additional rate imposed by the county government. Not all counties add a tax, and rates vary widely within the same state.

City or municipal sales tax is yet another layer added by cities and towns. Major cities often impose higher rates than surrounding suburbs or rural areas.

Special district taxes can be added for specific purposes — transit funding, stadium construction, tourism promotion, or other local projects. These are the taxes that make the rate at one intersection different from the rate two miles down the road.

This layering means there are over 11,000 distinct sales tax jurisdictions across the country. Two stores on opposite sides of a county line can charge different rates. This is why your receipt at a gas station in one neighborhood might show a different tax amount than a station three blocks away.

The 5 States With No Sales Tax

Five states impose no state-level sales tax at all. If you live in or shop in these states, the sticker price is the price you pay (in most cases):

Residents of these states save substantially over their lifetimes. Someone spending $40,000 per year on taxable goods in a state with a 7% combined rate pays $2,800 annually in sales tax — that's $28,000 over a decade that a resident of Oregon simply keeps.

Highest and Lowest Tax States

Among the 45 states (plus D.C.) that charge sales tax, rates vary significantly. The state-level rate is only part of the picture — combined average rates that include local taxes tell the real story of what consumers actually pay.

Highest combined average rates include Louisiana (around 9.55%), Tennessee (around 9.55%), Arkansas (around 9.44%), Washington state (around 9.29%), and Alabama (around 9.24%). In these states, local add-ons push the effective rate well above the state base.

Lowest combined average rates (among states that charge sales tax) include Alaska (1.76% average due to limited local taxes), Hawaii (4.44%), Wisconsin (5.43%), Wyoming (5.44%), and Maine (5.50%). Hawaii's rate is deceptive, however, because the state taxes many services and business-to-business transactions that other states exempt, so the tax touches a broader base of economic activity.

Colorado has the lowest state-level rate at 2.90%, but local taxes can push combined rates above 11% in some Denver-area locations. This is a perfect example of why the state rate alone doesn't tell you what you'll actually pay.

What's Taxable vs. Exempt

Not everything you buy is subject to sales tax. Every state with a sales tax defines its own list of taxable and exempt goods and services, and these lists vary more than most people realize.

Groceries

Most states exempt unprepared grocery food from sales tax — but not all. Alabama, Mississippi, and South Dakota tax groceries at the full state rate. Several other states like Arkansas, Illinois, Missouri, Tennessee, Utah, and Virginia tax groceries at a reduced rate. Prepared food (restaurant meals, deli items, hot food from a grocery store) is taxed in nearly every state, even those that exempt raw groceries.

Clothing

Clothing is fully taxable in most states, but a handful provide complete or partial exemptions. New York exempts clothing and footwear items under $110 per item. Pennsylvania exempts most everyday clothing. New Jersey, Minnesota, and several other northeastern states also exempt clothing. If you're planning a back-to-school shopping spree, where you buy can make a meaningful difference.

Other Common Exemptions

Prescription medications are exempt from sales tax in all states that charge a sales tax. Over-the-counter medications are taxed in most states, though some have begun exempting them.

Digital goods — ebooks, downloaded music, streaming services, software — have an inconsistent tax landscape. About half the states now tax digital goods. The trend is toward taxing them, as states adapt tax codes originally written for physical merchandise.

Services are generally not taxed in most states, though this is changing. Hawaii, New Mexico, South Dakota, and West Virginia broadly tax services. Most states tax specific services like dry cleaning, landscaping, or repair work while leaving others untaxed.

Use Tax: The Tax You Probably Owe

Every state with a sales tax also has a use tax, and it catches many people by surprise. Use tax applies when you buy something without paying sales tax — typically from an out-of-state seller or in a state without sales tax — and then use the item in your home state.

For example, if you drive to Oregon (no sales tax) and buy a $2,000 television, then bring it home to California, you technically owe California use tax on that purchase. The same principle applies to items bought from private sellers, at out-of-state craft fairs, or from any source that didn't collect your state's tax.

Most states include a use tax line on the annual income tax return. Enforcement on small consumer purchases is minimal, but states are increasingly aggressive about collecting use tax on big-ticket items — especially vehicles, boats, and other items that require registration.

How Sales Tax Affects Big Purchases

Sales tax is easy to ignore on a $5 coffee, but it becomes a serious cost factor on major purchases. The difference between tax rates — or whether a purchase is taxable at all — can amount to hundreds or thousands of dollars.

Vehicles are one of the largest sales tax purchases most people make. Most states charge sales tax on cars based on the purchase price, and the tax is collected at the time of registration. Some states tax the full purchase price; others allow credit for a trade-in, taxing only the difference. A few states charge flat fees or capped amounts instead of a percentage.

Appliances and furniture are taxable in all states with a sales tax. Timing purchases around tax-free weekends (offered by about 20 states) or buying in lower-tax jurisdictions can produce real savings on these items.

Online Shopping and Sales Tax

The landscape of online sales tax changed dramatically after the Supreme Court's 2018 South Dakota v. Wayfair decision, which allowed states to require out-of-state sellers to collect sales tax even without a physical presence in the state. By 2026, nearly every state with a sales tax has adopted economic nexus laws based on this ruling.

In practical terms, this means you now pay sales tax on most online purchases regardless of where the seller is located. Amazon, Walmart, Target, and virtually all major online retailers collect sales tax for every state that imposes one. Smaller sellers are subject to thresholds — typically $100,000 in sales or 200 transactions within a state before they're required to collect.

The days of saving money by buying online to avoid sales tax are largely over. The rare exceptions involve very small sellers who haven't reached a state's threshold, purchases from private individuals on platforms like Craigslist or Facebook Marketplace, and purchases from sellers in states with specific exemptions. Even in these cases, use tax technically applies.

One area that remains unsettled is marketplace facilitator laws. Most states now require platforms like Amazon, eBay, and Etsy to collect and remit tax on behalf of third-party sellers. This means even a small Etsy shop's customers pay sales tax, collected and handled by the platform itself.

Calculate Your Exact Sales Tax

Whether you're budgeting for a big purchase, comparing prices across state lines, or just want to know what you'll pay at checkout, knowing the exact combined rate for your location makes a difference.

The Bottom Line

Sales tax is one of those everyday costs that most people never think about until they're staring at a receipt that's noticeably higher than expected. The combined state and local rate where you live determines how much extra you pay on everything from groceries to cars, and the differences between jurisdictions are significant — easily thousands of dollars per year. Five states charge no sales tax at all, while others push combined rates past 10%. What gets taxed varies just as widely, with groceries, clothing, and digital goods treated differently depending on where you shop. Understanding how these rates layer together — and using tools like the Sales Tax Calculator to check the exact amount before a big purchase — helps you budget accurately and avoid sticker shock at the register.
