Washington Car Sales Tax: Use Tax on Out-of-State Purchases and the Luxury Tax

Washington charges sales tax on a car bought here and use tax on a car a Washington resident buys somewhere else. Both run at the state rate of 6.5 percent plus the local rate, and since January 1, 2026, the state adds a 0.5 percent motor vehicle sales and use tax on top. A Washington dealer collects the tax at the sale. On a car you buy in another state, or from a private seller, you pay it when you register the car with the Department of Licensing (DOL).

This guide is for Washington residents who buy a car out of state and bring it home. It covers the rate, how the value is set, the credit for tax paid elsewhere, Oregon purchases, the 8 percent luxury tax, a purchase from a New York dealer and the deadline to transfer the title. If you are moving to Washington with a car you already own, our guide to registering an out-of-state car in Washington covers the new resident exemption instead. The rules come from the Washington Department of Revenue (DOR), DOL and the New York State Department of Taxation and Finance.

What Is the Sales Tax on a Car in Washington?

The state rate of 6.5 percent plus your local rate, plus 0.5 percent. DOR's page on use tax sets use tax at the same state rate as sales tax, 6.5 percent, plus a local rate that depends on where the item is first used, and its Tax Rate Lookup Tool gives the combined rate for any Washington address.

The 0.5 percent is a separate charge. DOR's page on the motor vehicle sales/use tax describes it as an additional tax on all retail sales, leases and transfers of motor vehicles. The rate is 0.5 percent from January 1, 2026, up from 0.3 percent through December 31, 2025. Cars, SUVs, pickups, motorcycles and motorhomes are all covered, while trailers and repairs are not. Some websites still quote 0.3 percent, so check the date on any calculator you use.

Two more charges can apply to the same purchase. A vehicle priced above the luxury tax deduction owes the 8 percent luxury tax covered below. And DOL says residents of King, Pierce and Snohomish counties who live inside the Sound Transit district pay the Regional Transit Authority (RTA) excise tax when they buy a vehicle and at each tab renewal, which our Washington registration guide explains.

Do You Owe Washington Tax on a Car Bought in Another State?

Yes, if you live in Washington. DOR's page on vehicles brought into Washington from out of state says Washington residents who buy a vehicle outside the state and bring it in owe use tax on the value of that vehicle. Use tax is due when Washington sales tax was not paid, and a car is subject to one or the other, not both on the same transaction.

DOR counts you as a resident for sales and use tax if you take actions that show you intend to live in Washington on more than a temporary or transient basis. Three rules then set the bill:

• When. Use tax is paid when the vehicle is licensed and registered in Washington.
• Which rate. The rate is set by the owner's place of residence, not by where the car was bought.
• On what value. Use tax is based on the vehicle's fair market value, which is generally the amount paid to the seller, and never less than what you paid.

The 0.5 percent goes on the same bill. DOR says that when sales tax was not paid at the time of purchase, the motor vehicle sales/use tax applies as use tax when the vehicle is registered with DOL, and it names a purchase outside Washington as one of those cases.

How Is the Value Set on a Private Purchase?

From what you paid, unless it falls well below the market. DOL's use tax page explains how licensing offices work out the value. DOL takes average fair market values from Price Digests, an industry source DOR also uses. It may accept the purchase price instead when the fair market value is below $7,500 or when the price is within 20 percent of the fair market value.

If the car is worth less because of its condition, DOL lets you show it with a repair estimate from a registered mechanic, an appraisal from a registered dealer, or a lower average retail value from a source such as NADA or Kelley Blue Book. For a vehicle, DOL also asks for DOR's Declaration of Buyer and Seller Regarding Value of Used Vehicle Sold, signed by both of you and stating the price and the car's condition.

The bill of sale matters here. DOL's page on how to buy and register a vehicle says the sale price you and the seller enter on the Vehicle/Vessel Bill of Sale is used to calculate the use tax, so write the real price and keep the paperwork.

How Does the Credit for Tax Paid in Another State Work?

Dollar for dollar against the Washington use tax. DOR says that when you can show you paid sales or use tax in another state before bringing the vehicle into Washington, you may apply that amount against the Washington use tax. If the other state charged less than Washington, you pay the difference at registration.

Not every charge counts. DOR excludes licensing fees, lessor taxes and value added taxes such as Canada's goods and services tax (GST). Bring proof that shows the tax itself, such as the dealer's buyer's order or a receipt from the other state's tax office, not just the price.

What the seller collected decides how much credit you have. If no sales or use tax was paid in the other state, there is nothing to credit, so the full Washington use tax and the 0.5 percent are due at registration.

Is It Cheaper to Buy a Car in Oregon if You Live in Washington?

Not on tax. DOR uses Oregon as its own example: a Washington resident who buys items in Oregon for use in Washington, and pays no sales tax there, must report and pay use tax on the purchase. A car is no exception. DOL notes that Oregon does not have a state sales tax, so a car bought there arrives with no sales tax to credit.

When you register the car, you pay Washington use tax at your home rate on its value, plus the 0.5 percent, and the luxury tax if the price is high enough. Buying in Oregon can still make sense for the car itself, its price or its availability, but it does not lower what Washington collects.

Does the 8 Percent Luxury Tax Apply to a Car Bought Out of State?

Yes, if the price is above the deduction. DOR's page on the luxury motor vehicle tax describes an 8 percent tax, from January 1, 2026, on the sale or lease of a new or used motor vehicle priced above the deduction amount, in addition to sales tax and the 0.5 percent motor vehicle tax. If the luxury tax is not paid at the time of purchase, DOR says it applies when the vehicle is registered with DOL.

The tax applies only to the part of the price above the deduction, and DOR raises the deduction by 2 percent every July 1:

• January 1 to June 30, 2026. $100,000 per vehicle.
• July 1, 2026, to June 30, 2027. $102,000 per vehicle.

DOR adds any trade-in back to the selling price before taking off the deduction. A car bought out of state for $130,000 after July 1, 2026, with no trade-in, would owe the luxury tax on $28,000, which is $2,240. The 0.5 percent motor vehicle tax on $130,000 adds $650, and regular use tax at your home rate comes on top. These figures only illustrate the arithmetic.

DOR's exemptions list includes off-road vehicles and vehicles over 10,000 pounds gross weight other than motor homes. It also exempts sales to nonresidents from July 1, 2026, which helps a buyer from another state buying in Washington, not a Washington resident buying elsewhere.

What About a Car From a New York Dealer?

New York usually does not tax it, so Washington collects the full amount. New York's tax bulletin on motor vehicles, vessels and trailers (TB-ST-590) exempts a nonresident from New York State and local sales tax when the buyer has no permanent place of abode in New York, will not use the car in a New York job or business, and will not register it in New York, including a temporary registration. The buyer gives the dealer Form DTF-820 at the time of sale. Without it, the dealer collects New York sales tax at the rate where the car is delivered.

With the exemption, no New York tax is paid and Washington has nothing to credit, so your home rate and the 0.5 percent apply in full when you register. Our guide to buying a car in New York as an out-of-state resident walks through DTF-820. If the dealer does collect New York tax, keep the buyer's order showing it, since that is the proof DOR's credit needs.

Buyers from Florida dealers face a different setup, where Florida collects its own tax from nonresidents on a sliding rule. Our guide to Florida car sales tax covers Florida's side of that sale.

How Long Do You Have to Register the Car?

Fifteen days to transfer ownership. DOL's buy and register a vehicle page gives you 15 days after you buy a vehicle to transfer it into your name. After that, DOL charges $50 on the 16th day and $2 a day after the 16th day, up to $125.

The paperwork follows the private sale steps: the current title signed by every owner, a Vehicle Title Application signed in front of a licensing agent or a notary, the odometer disclosure for model year 2011 or newer, and the bill of sale with the price. DOL says you can mail the forms, which suits a purchase out of state when you will not be back right away. Call a vehicle licensing office first to confirm the forms, the amount and the mailing address.

What If You Are Moving to Washington, Not Buying?

Then a different rule applies. DOR exempts new residents from use tax on a private vehicle they acquired and used in another state more than 90 days before moving, as long as it is licensed in Washington within 30 days of the move. A car bought within 90 days of moving does not qualify and is taxed as described above. Our guide to registering an out-of-state car in Washington covers the exemption, the driver license that comes first, the RTA tax and the fees.

How Does Shipping Fit an Out-of-State Purchase?

The documents that set your tax travel apart from the car. Keep the title, the bill of sale and any proof of tax paid with you rather than in the glovebox, because the licensing office needs them for the value and the credit. Keep the signed bill of lading too, as a record of when the car was picked up and when it arrived.

Rivalane coordinates door to door transport to Washington with licensed carriers. Pickup and delivery dates are estimates, not guarantees, so plan the paperwork around the 15-day transfer window rather than the truck. Our page on New York to Washington car shipping covers that lane, the full list of car shipping routes covers others into the state, our page on car shipping in Washington covers deliveries across Washington, and the car shipping calculator prices the move.
