April 8, 2023

I am a serial entrepreneur and a consumer advocate. When I’m not helping car buyers, I love working on ventures that have a positive impact.
I run a cause marketing agency and serve on the board of Vayu Global Health where we are disrupting the medical industry and preventing the needless deaths of mothers and babies during childbirth.
It’s exciting to buy a new (or new for you) car, but it’s also far from cheap.
Things like sales tax and other fees are often forgotten about in the excitement of making a new car purchase. But in Washington, you’ll need to be prepared to spend additional money on these extra costs.
Here’s what to expect when it comes to taxes and fees in the state of Washington.

How Much Is the Car Sales Tax in Washington?
The state sales tax on a car purchase in Washington is 6.8%. This number is a sum of the base state sales tax of 6.5% plus a 0.3% “motor vehicle sales/lease tax.”
However, this does not include any potential local or county taxes. The average local tax rate in Washington is 2.368%, which brings the total average rate to 8.868%.
As an example, if you were to purchase a new sedan at a purchase price of $20,000, then you will have to pay an additional $1,360 in sales tax.
How to Calculate Washington Sales Tax on a Car
You can calculate the sales tax in Washington by multiplying the final purchase price by .068%.
For example, let’s say that you want to purchase a new car for $40,000, you would use the following formula to calculate the sales tax:
$40,000 x.068 = $2,720.
This means that your sales tax is $2,720 on a $40,000 purchase price.
Calculate Car Sales Tax in Washington Example:
- Initial Car Price: $40,000
- Sales Tax Rate: 6.8%
- Trade-In Amount: $5,000
- Incentives/Rebates: $2,000
Sales Tax = ($40,000 - $5,000) * .068
Sales Tax = $2,380
Remember that the total amount you pay for a car (out the door price) not only includes sales tax, but also registration, and dealership fees.

Do I Have to Pay Sales Tax on a Used Car?
The sales tax is the same 6.8% on a used vehicle.
For example, if you were to purchase a used car for $15,000, then you will have to pay an additional $1,020 in sales tax.
Which County Has the Highest Tax? Which Has the Lowest?
The city with the highest car sales tax is Tacoma with a 10.4% tax on all cars.
The county with the lowest car tax is Pierce County with a combined total tax rate of 8.3%.
Car Sales Tax for Trade-Ins in Washington
You don’t have to pay sales tax on trade-ins in Washington. In other words, be sure to subtract the trade-in amount from the car price before calculating sales tax.
As an example, let’s say you are purchasing a new SUV for $30,000 and your trade-in is worth $15,000. You will subtract the trade-in value by the purchase price and get $15,000. Therefore, your car sales tax will be based on the $15,000 amount.
Car Sales Tax on Private Sales in Washington
A sales tax is required on all private vehicle sales in Washington.
As an example, if you purchase a truck from a private party for $10,000, then you will pay 6.8% of that amount to the Washington DMV.
Tax on Rebates & Dealer Incentives
You do have to pay tax on dealer rebates and incentives in Washington. In other words, do not subtract the incentive/rebate amount from the car price before calculating sales tax.
As an example, if you are purchasing a new car for $50,000 with a $5,000 rebate, you will pay sales tax on the full $50,000 final cost of the car.
