Frequently asked questions
Why are my Seattle-area tabs so expensive?
The RTA (Sound Transit) excise tax — 1.1% of your vehicle's depreciated MSRP using a statutory schedule that depreciates slower than market value. On a newer $50,000 vehicle that's $400–$500 per year on top of standard fees. The rate is scheduled to drop to 0.8% in 2028 when older bonds retire.
Did Washington tab fees go up in 2026?
Yes — SB 5801 raised weight fees about 40% effective January 1, 2026 (a typical car's weight fee went from $25 to $35), with another increase scheduled for 2029. Title fees for dealer-processed sales rise to $40 in October 2026.
Can I avoid the RTA tax?
Only by garaging the vehicle at an address outside the Sound Transit district boundary — it's address-based, not county-wide. Parts of King, Pierce, and Snohomish counties fall outside the district.
