Washington Car Sales Tax Calculator (2026)

• Washington adds a 0.5 percent motor vehicle sales tax, effective January 1, 2026, to the 6.5 percent state retail sales tax, and local sales tax applies on top.
• Manufacturer rebates do not reduce the taxable price, though dealer rebates are treated as discounts and do.
• Trade-in value of a like-kind vehicle reduces the taxable selling price, but cash back on the trade-in does not count.

Figured with Washington's rules for a buyer in Seattle, at its 4.05% local rate.

• Used car, no trade-in$1,989

  $18,000 price. Taxed on $18,000.

• New car with a trade-in$2,763

  $35,000 price, $10,000 trade-in. Taxed on $25,000. The trade-in saves $1,105.

• New car with a trade-in and a rebate$3,315

  $45,000 price, $15,000 trade-in, $2,000 rebate. Taxed on $30,000. The trade-in saves $1,658. The rebate does not lower the tax.

These examples treat the agreed price as the taxable price. Where a state uses a book value instead, the tax can differ.

On a $30,000 car, tax runs from $2,640 in Yakima to $3,315 in Seattle, a difference of $675 among the 18 cities we list.

Before trade-in, for a buyer living in each city. In some states the rate follows the dealer's location instead; see the rules above and our methodology. Rates from dor.wa.gov, checked Nov 6, 2026.

The calculator covers a car bought from a dealer. These rules apply to other ways of buying or bringing a car to Washington.

Buying from a private seller

A car bought from a private seller owes Washington use tax, at the sales tax rate, on its fair market value, usually paid to the Department of Licensing at title transfer. The price paid is accepted if it is no more than 20% below the average retail value or that value is under $7,500; otherwise tax is on the retail value unless you document a lower value with a pricing guide, appraisal or repair estimate. (dor.wa.gov, checked Nov 10, 2026)

A car received as a gift

A car received as a gift or inheritance is exempt from use tax if the previous owner paid Washington sales or use tax and nothing is given in return; if it was registered in another state, credit is given for tax paid there. A gifted car with an outstanding loan generally does not qualify and is taxed on its fair market value. (dor.wa.gov, checked Nov 10, 2026)

Moving to Washington with your car

A new resident's personal car is exempt from Washington use tax if it was acquired and used in another state more than 90 days before moving and is licensed in Washington within 30 days of the move. A car bought in another state within 90 days before moving is not exempt. (dor.wa.gov, checked Nov 10, 2026)

Buying outside Washington

A Washington resident who buys a car in another state owes use tax on its value when registering it, at the rate for their place of residence. Sales or use tax shown to have been paid to the other state is credited against it, but licensing fees, lessor taxes and value added taxes are not. (dor.wa.gov, checked Nov 10, 2026)

Active-duty military

Washington residents on active duty for more than 6 months and stationed outside the state may not owe sales or use tax on a car bought and delivered outside Washington, unless it was acquired less than 30 days before discharge. Nonresident service members stationed in Washington may be exempt from vehicle excise and RTA tax by certifying a home of record outside Washington, and those staying less than 90 days may be exempt from sales and use tax with orders. (dol.wa.gov, checked Nov 10, 2026)

Deadline to pay

After you buy or receive a car as a gift, you have 15 days to transfer ownership into your name with the Department of Licensing, which is when use tax on a private purchase is usually paid. (dol.wa.gov, checked Nov 10, 2026)

Paying late

If ownership is not transferred within 15 days, the Department of Licensing charges a $50 late fee on the 16th day plus $2 for each day after that, up to $125. (dol.wa.gov, checked Nov 10, 2026)
