Establishing a tax on certain business activities related to surpluses generated under the zero-emission vehicle program.
House Bill 2077 establishes a new tax on certain vehicle manufacturers. This tax applies to profits generated from surplus zero-emission vehicle (ZEV) credits, which are earned when a manufacturer exceeds the state's ZEV sales requirements. The bill requires the Department of Ecology to share manufacturers' ZEV credit activity with the Department of Revenue, and manufacturers must report the prices of ZEV credit transactions. The collected tax revenue is intended to be reinvested into programs that further promote cleaner vehicles.

MINOR
The document was updated from a draft version (Substitute Bill) to the final certified version passed by the Washington State Legislature. This change adds official certification signatures, specific vote counts, and filing dates, confirming the bill is now law.
Scope change
The substantive scope of the bill remains unchanged; the text continues to establish a tax on surplus credits from the zero-emission vehicle program.
ENFORCEMENT
Added official certification of enrollment, including signatures from the Chief Clerk and Secretary of State, and specific vote counts for both the House and Senate.
ADDED
Added the legislative session details (69th Legislature, 2025 Regular Session) and the final passing dates for the House and Senate.
TECHNICAL
Removed the draft bill identifier (H-2255.1) and the 'Read First Time' date, as these are no longer relevant for the enacted law.
