Tax preference performance statement—2025 c 417 ss 809 and 810: "This section is the tax preference performance statement for the tax preferences contained in sections 809 and 810, chapter 417, Laws of 2025. This performance statement is only intended to be used for subsequent evaluation of the tax preference. It is not intended to create a private right of action by any party or be used to determine eligibility for preferential tax treatment.

(1) The legislature categorizes the tax preferences as ones intended to induce certain designated behavior by taxpayers, as indicated in RCW 82.32.808(2)(a).

(2) It is the legislature's specific public policy objective to increase the use of zero emission buses by transit agencies in Washington. It is the legislature's intent to extend the tax incentive available to zero emission buses to further emission reductions, as well as reductions in fine particulates, in the state.

(3) To measure the effectiveness of the tax preferences in sections 809 and 810, chapter 417, Laws of 2025 in achieving the public policy objectives described in subsection (2) of this section, the joint legislative audit and review committee must evaluate the number of zero emission transit buses titled in the state and the estimated resulting carbon emission and fine particulate reductions.

(4) In order to obtain the data necessary to perform the review in subsection (3) of this section, the department of licensing, department of revenue, and department of ecology must provide data needed for the joint legislative audit and review committee analysis. In addition to the data source described under this subsection, the joint legislative audit and review committee may use any other data it deems necessary." [ 2025 c 417 s 808.]
