How Washington DMV Fees Are Calculated in 2026
Washington State vehicle registration involves a $43 base fee plus one potential gotcha: if you live in King, Pierce, or Snohomish counties, you also pay the RTA (Regional Transit Authority) tax — a value-based annual charge that can add hundreds of dollars to your bill.
Base registration fee — $43
Washington's base annual registration is $43 for passenger vehicles. Plus a $15 license service fee. Motorcycles are $30.
RTA Tax — the big variable
The RTA tax is an annual value-based fee charged only in King, Pierce, and Snohomish counties (greater Seattle metro area). It's calculated at 1.1% of the vehicle's depreciated value. On a new $40,000 vehicle, that's $440 extra per year. On a 5-year-old $25,000 vehicle, roughly $165.
EV surcharge — $150/year
Washington charges $150 extra annually for electric vehicles. Washington also offers a sales tax exemption on EVs under $45,000 (check current eligibility as this has changed over time).
Title fee — $15
WA DOL charges $15 for a certificate of title.
Sales tax — varies widely
State sales tax is 6.5%, but Seattle (King County) reaches 10.25% with city and transit additions. Spokane is around 8.9%. Rural counties can be close to the base 6.5%.
