How Much are Used Car Sales Taxes in Washington?

How is Used Car Sales Tax Calculated in Washington?

When you purchase a car in the state of Washington, you have to pay the motor vehicle sales/lease tax, also known as the motor vehicle surtax. This tax amounts to three-tenths of one percent (0.3%) of the motor vehicle purchase price. It applies to all retail sales, leases, and transfers of motor vehicles.

Vehicle’s Purchase Price vs Fair Market Value

You may think you can outsmart the government by negotiating a low "official" purchase price and paying the rest in a side transaction. But the Washington Department of Motor Vehicles (DMV) is onto you. If you’re buying the car from a private party, you must declare the car's fair market value to the DMV and pay the appropriate amount of sales tax based on that value.

If the DMV suspects that the purchase price of the vehicle was artificially decreased, they will calculate sales tax based on the car’s fair market value. The DMV establishes what the car is worth on the open market by referring to Price Digests or other reliable sources of information about used car prices. If the DMV concludes that the car's fair market value is greater than the selling price, the sales tax can be assessed based on the fair market value.

If you bought a car for less than its fair market value and think it's really worth less than the average fair market value, you can make your case for a lower value by submitting a verified appraisal or an affidavit from the seller.

Keep in mind that the Department of Revenue may evaluate and audit buyer and seller declarations on the value of used vehicles sold. Sometimes, an audit can result in additional taxes, interest, and fines.

Do You Pay Taxes When You Buy a Car From a Private Seller in Washington?

The used car sales tax rate for the state of Washington is 6.5% of the car’s selling price, whether you buy from a private seller or a dealer. The tax law does not discriminate between the two.

Cities and counties collect additional taxes on car leases and purchases, and the rates can range from 0.5% to 3.5%, depending on where you live. That can bring the total amount of sales tax in Washington State to between 7.3% and 10.6%, with the average combined rate of 8.84%.

If you want to register and pay taxes in cities like Goldendale and Lyle, you’ll be facing the state’s lowest rates (7.5%). Residents of Lynnwood and Bothell aren’t so lucky, as their car taxes are the highest in the Evergreen State (10.6%).

Here are the combined vehicle sales taxes for some cities in Washington State:

Seattle: 10.4%

Vancouver: 8.6%

  • Registration fee: $50
  • Plate transfer fee: $10
  • Vehicle title fee: $26

How to Pay Washington Vehicle Sales Tax

Here's how to pay car sales tax in Washington after you’ve purchased a used car from a private seller:

1. You and the seller each complete the Vehicle/Vessel Bill of Sale. When you buy the car on PrivateAuto, we provide an official Washington bill of sale and prompt both of you to sign it in our app at the appropriate stage of the transaction process.
2. Calculate the amount of sales tax due depending on the tax rate for your city and county. The Washington sales tax on cars is 6.5%. To determine the sales tax, multiply the vehicle's price by 0.0650. For example, if you paid $10,000 for a car, the sales tax would be $650. If you live in a city or county where additional sales tax is levied, add the local tax rate to get your total tax rate, then divide that rate by 100 and multiply the car's purchase price by the resulting figure. Determine the amount of sales tax you owe based on the vehicle’s purchase price. (If it’s a gift, the tax amount is zero.) Calculating how much your car will cost after taxes can be a nuisance, but our sales tax calculator might come in handy.
3. Sign the Vehicle Title Application in front of a notary public or a licensing agent.
4. Submit your forms and payments. You can submit documentation to the local office or online.
5. If needed, also submit an affidavit of Loss/Release of Interest or Odometer Disclosure Statement.
6. Get payment proof from the Washington Department of Motor Vehicles.
7. Get your new registration and title. Once you've paid the sales tax and turned in the necessary paperwork, you'll get your new registration and title for the car. The title and registration will show that you bought the car and that the sales tax has been paid. You will also get new license plates.

If you buy a car in a state that levies no sales or use tax and plan to register it in Washington, you must pay taxes in Washington state.

How to Avoid Paying Sales Tax on a Car in Washington?

There’s no way around it—property taxes, income taxes, sales taxes, and other taxes are part of life. You are required by law to pay sales taxes on used cars in Washington or any other state. However, you may qualify for an exemption.

Washington Car Sales Tax Exemptions

Vehicles received as gifts are generally exempt from taxation. Here are some tax exemptions for used vehicle purchases, as listed on the Washington Vehicle Registration website:

If someone gifted you the vehicle and you can provide proof that the person who donated the vehicle to you paid sales or use tax on it, you should be exempt.
If you purchase a motor vehicle while on active military duty, you may avoid paying car sales tax. Read more about this here.

Many people think buying from car dealers is a magical solution to avoid all the hassle (and perhaps a tax here and there). In fact, you pay more when you go to a dealer. Dealerships charge a "documentation fee" above and beyond the taxes you pay to the state. The average documentation fee in the state of Washington is $150.

Avoid documentation fees and get lower prices when you buy used cars from private sellers right here on PrivateAuto.
