Establishing a tax on certain business activities related to surpluses generated under the zero-emission vehicle program.

SB 5811 establishes an excise tax on certain business activities related to surplus zero-emission vehicle (ZEV) credits generated by vehicle manufacturers in Washington state. The existing ZEV program requires manufacturers to sell a minimum percentage of ZEVs or acquire credits, allowing some to generate surplus credits. This bill imposes a 2% tax on the sale price of ZEV credits sold to other manufacturers, and also applies to the pooling and banking of these surplus credits. The intent is to tax these "windfall profits" and reinvest the funds into other programs that promote cleaner vehicles and support state climate goals.
