WA HB1921

Establishes a per-mile road usage charge of 2.6 cents to replace declining fuel tax revenue, with a voluntary program beginning July 1, 2027 for electric/hybrid vehicles and a mandatory program phasing in from July 1, 2029 through July 1, 2035 based on vehicle fuel economy ratings (starting with 40+ MPG vehicles and eventually covering all vehicles rated 20+ MPG)

Participants enrolled in the road usage charge program receive waivers of the $100 electric vehicle registration fee and $75 transportation electrification fee, plus a fuel tax credit to avoid double taxation

Creates a 10% road usage assessment on top of the road usage fee for mandatory program participants, with proceeds dedicated to multimodal transportation including rail, bicycle, pedestrian, and public transit

Requires vehicle owners to report odometer mileage for fee calculation, with strong privacy protections prohibiting collection of specific location data without explicit consent and limiting data collection to information necessary for fee calculation

Establishes the road usage charge highway account (for highway preservation/maintenance) and road usage assessment account (for multimodal purposes), and directs the Joint Transportation Committee to study tribal impacts, heavy vehicle fees, and off-road vehicle funding by various 2026-2028 deadlines
