Overview
Puget Sound riders also pay the Sound Transit RTA excise: motorcycles registered in the district owe the same 1.1% of depreciated MSRP as cars, which adds $100+ a year on newer bikes. Electric motorcycles get their own $30 EV fee - a bargain next to the $225 electric cars pay. Buying a bike triggers the standard Washington purchase math: use tax at your combined vehicle rate (fair-market-value rule included), title transfer within 15 days, and $20 for an original motorcycle plate.

Washington motorcycle fees FAQ
How much are motorcycle tabs in Washington?
About $82.75 a year outside the Sound Transit district and TBD cities: $30 tab fee + $35 weight fee + $6 filing + $11 service + $0.75 in small DOL fees. Inside the RTA district, add 1.1% of the bike's depreciated MSRP - roughly $145 more on a two-year-old $14,000 bike.
Why does my motorcycle pay a car's weight fee?
The weight-fee statute (RCW 46.17.365) covers motorcycles by reference and its lowest tier is 'up to 4,000 lbs' - which captures every motorcycle ever made at the same $35 as a compact sedan. Riders have complained for years, but the 2026 fee revision raised the tier from $25+$10 to $35 rather than carving bikes out.
Do motorcycles pay the RTA car-tab tax?
Yes - the Sound Transit MVET applies to motorcycles registered at district addresses, at the same 1.1% of MSRP run through the 1996 depreciation schedule. A new $20,000 bike in Seattle owes $220 of RTA on top of its tabs; by year five it's still about $163.
What does it cost to buy and register a used motorcycle in Seattle?
On a $9,000 private-party bike: about $995 in use tax (≈11.05%), $39.50 in title fees, $82.75 in tabs, $50 Seattle TBD fee, $20 for a plate if it needs one, plus the RTA line for the bike's age - call it $1,300–$1,400 all-in. And remember the fair-market-value rule: a suspiciously low price gets taxed at book value.
How much extra does an electric motorcycle cost to register?
$30 a year (RCW 46.17.323) - Washington deliberately set it below the $225 electric cars pay. An electric motorcycle's total renewal is about $112.75 plus any TBD/RTA lines for your address.
Do mopeds and scooters register the same way?
Mopeds have their own cheaper lane: a $30 license fee but no weight fee, and they're exempt from the RTA excise in practice because they carry no MSRP-based valuation. Anything titled as a motorcycle - most scooters over 50cc - pays the full motorcycle stack including the $35 weight fee.
Is there a motorcycle inspection or emissions test in Washington?
Neither. Washington ended emissions testing entirely in January 2020 (motorcycles were never included anyway) and has no periodic safety inspection. You do need a motorcycle endorsement on your license and a DOT helmet - but neither shows up on the registration bill.
