Washington adds a motor vehicle sales/use tax of 0.5% from 1 January 2026 (it was 0.3% through 31 December 2025) on top of regular retail sales tax, which is a 6.5% state rate plus a local rate (Washington Department of Revenue, read October 2026). On a $30,000 vehicle the additional tax is $150, before sales tax.

Introduction
The Washington Department of Revenue calls it an additional tax on all retail sales, leases and transfers of motor vehicles. It sits alongside the ordinary retail sales tax and funds transportation improvements. Sellers collect it at the time of sale; if sales tax was not paid, use tax applies at the time the vehicle is registered with the Department of Licensing.
This guide sets out the two layers, the date the additional rate rose, what is excluded, and the lease rule, and the separate luxury vehicle tax. The local sales tax rate depends on where the buyer receives the vehicle, so the examples leave it out rather than guess a figure.
Section 01
The Two Layers of Tax
The state rate of retail sales tax is 6.5%, and the Department says the local rate varies by city and/or county. The additional motor vehicle tax is separate: "Effective Jan. 1, 2026, the rate is 0.5% (0.005)." Through 31 December 2025 the rate was 0.3%.

These are illustrations only. The local portion of sales tax comes on top and depends on location.
Section 03
Luxury Vehicle Tax on Expensive Vehicles
Since 1 January 2026 Washington also has a separate luxury motor vehicle tax: 8% on the sale or lease of a new or used motor vehicle priced at more than $100,000. The Department of Revenue says it is in addition to retail sales tax and the motor vehicle sales/use tax. The deduction is $100,000 through 30 June 2026, $102,000 from 1 July 2026 to 30 June 2027, and rises 2% each 1 July. For a purchase the taxable amount is the selling price plus any trade-in property, minus the deduction; for a lease it is the fair market value at lease inception, minus the deduction. Exemptions include commercial motor vehicles, vehicles over 10,000 lb gross weight rating other than motor homes, sales to nonresidents (from 1 July 2026) and recreational vehicles from 1 July to 31 December 2026. If the tax is not paid at purchase, it applies when the vehicle is registered with the Department of Licensing.
Our arithmetic: a $120,000 vehicle with no trade-in bought from 1 July 2026 to 30 June 2027 has a taxable amount of $18,000 and a luxury tax of $1,440, on top of the other taxes. The $30,000 examples above are below the threshold, so this tax does not apply to them.
Section 04
What Is and Is Not Covered
Covered: motor vehicles licensed for on-road use, including SUVs, recreational vehicles and motorhomes, plus demonstration, executive and service vehicles on which the dealership owes use tax.
Not covered: farm tractors, farm vehicles, off-road vehicles, non-highway vehicles, trailers and snowmobiles are outside the definition of a motor vehicle for this tax.
Subject to regular sales tax only: retail car rentals under the rental car tax, post-sale equipment and installation charged to the owner, maintenance agreements and warranties, and repairs.
Exemptions follow sales tax: a sale of a motor vehicle that is exempt from sales tax is also exempt from the motor vehicle sales/use tax, for example sales to carriers in interstate commerce, to the US Government, or to a Tribe or Tribal citizen.
Section 05
Private Sales, Out-of-State Purchases and Leases
Private or out-of-state purchase: if sales tax was not paid at purchase, use tax applies when the vehicle is registered with the Department of Licensing. This happens when a vehicle is bought from a private party or outside Washington.
Partial exemption for public safety tax: a partial exemption removes the voter-approved public safety component of the local sales tax on retail sales of motor vehicles and on the first 36 months of lease payments.
Long leases: leases that run beyond 36 months do not qualify for the partial exemption, so lessors use the regular rate and location codes for payments after the 36th month, and the motor vehicle sales tax still applies.
