In most cases, yes. Do you have to pay sales tax? If you live in one of the 45 states or the District of Columbia that impose a general sales tax, the default answer on retail purchases is yes, with combined state and local rates typically landing between 6% and 11%. Whether the tax appears on your receipt depends on what you’re buying, who’s selling it, and where the transaction happens. And when a seller doesn’t collect, the obligation doesn’t vanish. It shifts to you as a “use tax” you’re supposed to report on your own.
Why Some Sellers Charge Tax and Others Don’t
A state can only require a business to collect sales tax if that business has a sufficient connection to the state, a concept the law calls nexus. For decades this meant a physical presence: a storefront, a warehouse, employees on the ground. A retailer with no footprint in your state had no duty to charge you tax, even if it shipped to your door every week.
That changed in 2018, when the Supreme Court in South Dakota v. Wayfair, Inc. allowed states to require collection from remote sellers based on their sales volume alone. South Dakota’s threshold was $100,000 in annual sales or 200 separate transactions, and most states adopted similar benchmarks. Several states, including Wisconsin, Maine, South Dakota, and Louisiana, have since dropped the transaction count and kept only the dollar figure.
The bigger practical shift for online shoppers came from marketplace facilitator laws. Roughly 46 states now require platforms like Amazon, eBay, Etsy, and Walmart.com to collect and remit sales tax on the transactions they handle, regardless of whether the individual third-party seller would have owed anything on its own. If you see sales tax on your Amazon receipt from a small vendor you’ve never heard of, that’s why. The gap still exists when you buy directly from a small business’s own website and that business hasn’t crossed your state’s economic nexus threshold. Those are the transactions where use tax obligations still commonly arise.
What’s Taxable
The broadest and most consistent category is tangible personal property: anything you can pick up and carry out of a store. Electronics, furniture, appliances, clothing in most states, and vehicles all fall here. If you’re buying a physical product at retail, assume it’s taxable unless your state has carved out a specific exemption.
Digital goods are increasingly treated the same way. Roughly 40 states tax at least some digital products, including software downloads, streaming subscriptions, e-books, and digital music. The rules vary. Some states tax digital goods broadly, others only reach downloads that have a physical equivalent. Cloud-based software subscriptions sit in a gray area: about half the states tax Software as a Service in some form, and half don’t. Pennsylvania taxes it as tangible property, Texas taxes 80% of the charge under its data-processing rules, and California and Florida exempt it entirely.
Professional services like legal advice, accounting, and consulting remain untaxed in most states. The historical rationale is that sales tax targeted goods, not labor. But the line keeps moving, particularly for services tied to a physical result, such as repair work, landscaping, or custom fabrication. If you’re paying someone to do something that produces a physical outcome, check whether your state taxes it.
Common Exemptions
About 33 states fully exempt unprepared groceries. A few others tax them at a reduced rate, typically 1% to 4%. Prepared food, like a deli sandwich or a restaurant meal, is almost always taxed at the full rate even in states that exempt raw ingredients. Prescription medications are exempt in nearly every state.
A handful of states, mostly in the Northeast, exempt everyday clothing outright. Others achieve a similar effect through sales tax holidays that create a temporary tax-free window, usually with a per-item price cap. A $50 pair of jeans qualifies; a $500 designer jacket may not.
Government agencies and qualifying nonprofits can buy goods without paying sales tax, but they have to present the right documentation at the register. Some states issue numbered exemption certificates; others accept a purchase order or agency credit card. The exemption covers purchases made with the organization’s funds for its own purposes, not personal purchases by employees who happen to work there.
Businesses buying inventory for resale can avoid tax at the wholesale level by presenting a resale certificate. The tax is meant to be collected once, when the item reaches its final consumer. Misusing a resale certificate for personal purchases is treated seriously, with penalties ranging from percentage-based surcharges on the unpaid tax to misdemeanor charges in states that treat intentional misuse as evasion.
Use Tax: When No One Collects
When you buy something taxable and the seller doesn’t charge sales tax, you owe the equivalent amount as use tax to your home state. The rate matches your local sales tax rate. It applies whether you bought the item from an out-of-state retailer, at a garage sale, or from an overseas vendor. Every state that has a sales tax also has a use tax, and the legal obligation is real even though compliance is famously low.
Reporting typically happens on your annual state income tax return, which usually has a dedicated line for it. If you kept receipts, you report the actual amount of untaxed purchases. If you didn’t, many states offer a simplified lookup table based on your income bracket. These safe-harbor estimates are small, sometimes just a few dollars, and are designed to cover minor items bought while traveling. Anything expensive, like a vehicle or major appliance purchased without tax, has to be reported separately at its actual value.
Enforcement against individuals for small amounts is rare, but the obligation becomes very real for large purchases. States routinely cross-reference vehicle registrations and boat titles against tax records, and a car bought out of state without tax will get flagged. Late-payment penalties generally start around 5% and climb to 20% or more of the balance, plus interest.
States Without a General Sales Tax
Five states impose no statewide sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon. Residents and visitors don’t see sales tax added to most retail purchases, which makes these states popular destinations for big-ticket shopping trips.
The exemption isn’t always clean. Alaska allows local municipalities to impose their own sales taxes, and roughly 110 of them do, with rates from 1% to 7%. Montana allows a limited local resort tax in certain tourist areas. New Hampshire, Delaware, and Oregon have no local sales taxes at all.
Living in a no-sales-tax state doesn’t help much with major purchases you’ll use elsewhere. Buy a vehicle in Oregon and register it in a state with sales tax, and you’ll owe use tax to your home state at titling. That bill runs 6% to 10% of the purchase price depending on where you live. Some states offer a credit for taxes paid in the purchase state, but when the purchase state charges zero, there’s nothing to credit.
Buying Across State Lines
Cross-border purchases are where the rules get genuinely confusing, and vehicles are the most common flashpoint. Sales or use tax is generally owed where the vehicle will be registered and primarily used, not where it was purchased. Most states let out-of-state buyers claim an exemption from the seller’s state tax, but you have to request it and complete the paperwork at the dealership. If you don’t, the dealer may collect their state’s tax and you’ll still owe use tax at home, potentially paying twice.
The same principle applies when you move from a no-tax state to one with sales tax. Existing possessions generally aren’t taxed, but a vehicle or boat you bring along may trigger use tax or registration fees in the new state. Several states charge a flat infrastructure or titling fee instead of a percentage-based use tax on vehicles brought in from out of state.
International Orders
Buying from a foreign retailer doesn’t exempt you from federal duties or state use tax. The $800 de minimis threshold that used to let low-value imports enter duty-free was suspended effective August 29, 2025. All imported goods, regardless of value, are now subject to applicable duties, taxes, and fees. A $30 item from an overseas seller may now face customs charges that didn’t exist a few years ago.
State use tax applies on top of whatever you pay at customs. Even if you’ve paid foreign taxes or federal duties, your state still expects use tax on the purchase price if no state sales tax was collected at checkout. Marketplace facilitator laws help here too: if you buy an imported product through a major platform that collects tax, your use-tax obligation is already covered. The gap shows up when you order directly from a foreign seller’s own site.
Sales Tax Holidays
More than 20 states run temporary sales tax holidays, usually timed around back-to-school season in late summer. Specific categories become tax-free up to a per-item cap: clothing and footwear (often capped at $100 per item), school supplies (typically $30 to $50), and computers (with caps ranging from $500 to $1,500). Several states run separate holidays for emergency preparedness supplies like generators, batteries, and weather radios ahead of storm season, and a few have experimented with energy-efficient appliances and hunting gear.
The savings are real but modest for most shoppers. Timing a laptop purchase to fall within your state’s holiday can save $50 to $100. On a pack of notebooks, the savings are pennies.
