Sales Tax by State: What Online Shoppers Should Know

Five states have no statewide sales tax, but if you shop online, the tax you pay follows your delivery address, not the seller. Since the 2018 Wayfair ruling, online retailers collect tax for the buyer's state, and combined state-plus-local rates run as high as 10.13 percent. Here is how the system actually works and how to check the exact rate on anything you buy.

Rate figures in this article are snapshots as of 2026. State rates move rarely but local rates change often, so verify the current number with your state's department of revenue before relying on it for a large purchase.

Which states have no sales tax?

Five states have no statewide sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon. Shoppers in Delaware and Oregon genuinely pay zero on most purchases, which is why Delaware malls near the Pennsylvania and New Jersey borders do such brisk business.

Alaska carries an asterisk worth knowing. It has no state-level tax, but local jurisdictions are free to impose their own, and many do: the average local rate there runs about 1.76 percent. New Hampshire has no sales tax but is famous for high property taxes, which is how the state funds itself instead. The broader lesson: no-sales-tax states are not no-tax states. They simply collect their revenue through income taxes, property taxes, or other levies. Judge a state's total tax burden, not one line of it.

How high can combined sales tax rates go?

The state rate is only half the story. Cities, counties, and special districts pile local taxes on top, and in some places the local add-ons exceed the state tax itself. The Tax Foundation's midyear 2026 ranking puts the highest average combined rates in Louisiana (10.13 percent), Tennessee (9.61 percent), Washington (9.57 percent), Arkansas (9.48 percent), and Alabama (9.46 percent). California has the highest state-level rate at 7.25 percent, with local add-ons pushing its combined average to about 8.82 percent.

Put that in concrete terms: a $999 laptop rings up about $101 in sales tax in Louisiana and $0 in Oregon. On a $35,000 car, the difference between a 10 percent combined rate and a 6 percent one is $1,400, which is worth knowing before you sign. Our Sales Tax Calculator runs these numbers for any purchase amount so you can see the tax before you commit. And remember the snapshot warning above: confirm the live rate with your state's revenue department, because local rates shift with ballot measures and new district taxes.

Why do online retailers charge sales tax now?

For most of the internet's history, online shopping was effectively tax-free unless the seller had a store or warehouse in your state. That ended in 2018 with South Dakota v. Wayfair, when the Supreme Court ruled that states can require out-of-state sellers with substantial economic activity, typically $100,000 in sales or 200 transactions a year in the state, to collect sales tax. Physical presence stopped being the test; economic presence became the test.

Every state with a sales tax then passed marketplace facilitator laws, which go one step further: they make the platform itself, Amazon, eBay, Etsy, Walmart Marketplace, responsible for collecting tax on every transaction, including sales by small third-party sellers who would never hit the threshold on their own. That is why the tax line appears on nearly every online checkout today. The tax-free internet checkout is over, and it has been over for years. If a small seller's site still shows no tax, that usually means the seller is below the threshold, not that the purchase is exempt.

Whose tax rate applies: yours or the seller's?

Yours, always. Online sales tax is destination-based: the rate is set by the address where the item is delivered. Order from a Florida seller to a Texas address and you pay the Texas rate for your specific city and county. Two customers buying the identical item from the identical website can see different tax totals because they live in different jurisdictions.

This has two practical consequences shoppers miss. First, buying from a seller in a no-tax state does not help you: an Oregon seller shipping to California collects California tax. Second, moving changes your online tax bill the day your delivery address changes, which is one more small line item in the true cost of relocating. The seller's location is irrelevant to the math in nearly every state.

What is use tax, and when does it hit you?

Use tax is the backup tax your home state charges when no sales tax was collected on a taxable purchase: goods bought out of state and brought home, or online orders from sellers too small to collect. Legally you owe it, and most state income tax returns include a line asking you to declare untaxed purchases. Enforcement against individuals buying small items is rare, but businesses get audited on this routinely.

For shoppers, the honest summary is that marketplace facilitator laws made use tax mostly a non-issue on everyday online buying, because the platform already collected. It still matters in the edge cases: a purchase from a tiny out-of-state shop below the economic nexus threshold, or goods you physically buy while traveling in a no-tax state and bring home. Knowing the concept exists keeps you from accidentally assuming "no tax collected" means "no tax owed."

How do you check the exact rate before you buy?

For everyday shopping, the checkout page does the work: the retailer calculates the destination-based rate for your address. But when you want to verify, plan a big purchase, or sanity-check a suspiciously high tax line, go to the source. Every state's department of revenue publishes current rates and usually offers a lookup tool by address or ZIP code.

One caution about ZIP code lookups: a single ZIP can span multiple tax jurisdictions, so the result is an estimate. For a large purchase, use an address-level lookup from the state itself. For quick math on any amount, our Sales Tax Calculator applies state and typical local rates instantly, and the Discount Calculator helps you compare sale prices after tax, which is the number that actually matters when two stores advertise different pre-tax prices.

Frequently Asked Questions

Which states have no sales tax in 2026?

Five states have no statewide sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon. Alaska is the asterisk: it has no state-level tax, but many local jurisdictions there charge their own, averaging about 1.76 percent locally. The other four truly charge zero at the state level, though local add-ons are rare but possible. Note that no-sales-tax does not mean no-tax: these states fund themselves through other taxes, and several of them make up for it with high property or income taxes instead. Moving to New Hampshire for the shopping and staying for the property tax bill is a classic rookie mistake.

Which states have the highest sales tax rates?

At the state level, California is highest at 7.25 percent. But the number you actually pay includes local taxes, and on that combined measure the Tax Foundation's midyear 2026 ranking puts Louisiana first at 10.13 percent average combined, followed by Tennessee (9.61 percent), Washington (9.57 percent), Arkansas (9.48 percent), and Alabama (9.46 percent). A $999 laptop costs about $101 in tax in Louisiana versus zero in Oregon, which is real money on big purchases. Always verify the current rate with your state's department of revenue before making plans around these figures, because local rates change frequently.

Why do online retailers charge me sales tax now?

Because of the 2018 Supreme Court decision in South Dakota v. Wayfair. Before that ruling, states could generally only force retailers with a physical presence, like a store or warehouse, to collect sales tax. Wayfair threw that rule out: now a state can require any seller with enough economic activity there, typically $100,000 in sales or 200 transactions a year, to collect its tax. Every state with a sales tax has since passed marketplace facilitator laws, which make platforms like Amazon, eBay, and Etsy collect tax on behalf of their third-party sellers. The tax-free internet checkout is effectively over, and it has been for years.

Do I owe sales tax based on my state or the seller's state?

Yours. Online sales tax is destination-based: the rate is determined by where the item is delivered, not where the seller sits. If you live in Texas and buy from a seller in Florida, you pay Texas tax at the rate for your delivery address, including any local add-ons for your city and county. That is why two buyers ordering the same item from the same website can see different tax totals. It also means moving changes your online tax bill immediately. The seller's location is irrelevant to the calculation in nearly every state.

What is use tax, and do I actually have to pay it?

Use tax is the backup tax for purchases where no sales tax was collected: you owe it to your home state on taxable items you buy elsewhere and bring home, or buy online from a seller that did not collect. Legally, yes, you owe it, and most state income tax returns include a line where you are supposed to declare untaxed purchases. In practice, states rarely chase individuals for small amounts, but they absolutely do audit businesses. Since marketplace facilitator laws now make the big platforms collect automatically, use tax mostly matters for purchases from small out-of-state sellers that fall below economic nexus thresholds.

Are groceries and clothing taxed the same as other goods?

No, and the differences are bigger than most shoppers realize. Many states exempt groceries entirely or tax them at a reduced rate: Tennessee, for example, taxes groceries at a lower rate than its 7 percent general rate. Clothing gets special treatment in a few states, most famously Pennsylvania, which exempts most everyday clothing. Then there are the quirks: some states tax candy but not groceries, or tax soft drinks differently from juice. Digital goods are the newest battleground, with a growing number of states taxing downloads, streaming, and software subscriptions. Check your state's specific exemptions before assuming anything.

What are sales tax holidays and are they worth it?

Sales tax holidays are short windows, usually a weekend, when a state suspends tax on specific categories like school supplies, clothing, or hurricane preparedness gear. About a dozen states run them, mostly in late summer around back-to-school season. They can save real money if you were going to buy the items anyway: skipping a 7 percent tax on $500 of school supplies is $35 back. My take: use them as a calendar reminder to buy what you already need, not as a reason to buy what you do not.

How can I check the exact sales tax rate for my address?

Start with your state's department of revenue website, which publishes current state rates and usually a lookup tool for local add-ons by ZIP code or address. That is the authoritative source, and it matters because local rates change far more often than state rates. For quick estimates, our Sales Tax Calculator applies state and typical local rates to any purchase amount. One warning: ZIP codes can span multiple tax jurisdictions, so a ZIP-based lookup is an estimate. For a business calculating tax on customers, or a large purchase where every fraction of a percent matters, use an address-level lookup from the state itself.

Can I avoid sales tax by buying from a no-tax state?

Not legally, if the item is delivered to your home state. Remember the destination rule: the tax follows the delivery address, so ordering from an Oregon seller to a California address means California tax, collected by the seller under marketplace facilitator or economic nexus rules. Driving across the border and bringing goods home yourself triggers use tax in your home state, which you legally owe. The only clean way to pay zero is to both buy and take delivery in a no-tax state, which is why the classic advice is about shopping while traveling, not about gaming online checkout.

Do sales tax rates change often?

State-level rates change rarely: most states have held the same statewide rate for years. Local rates change constantly, as cities and counties add fractions of a percent for transit, schools, stadiums, and other projects, often through ballot measures. That is why combined rates drift upward over time even when the state rate never moves. For shoppers, the practical effect is small on any single purchase. For anyone doing tax planning or running a business, it means the rate you used last year deserves a fresh check. Treat any published rate table, including this article, as a snapshot: confirm the live number with your state's revenue department.
