This bill creates new sales tax and corresponding use tax exemptions in chapters 82.08 and 82.12 RCW for labor, services, building materials, equipment, and tangible personal property used in a "qualified salmon recovery project." The exemptions apply only when a qualified project sponsor has an exemption certificate issued under the bill and do not apply to property or services received before August 1, 2025. The bill establishes a procedural framework: a qualified salmon recovery project sponsor (a private, public, or tribal entity that has received state funding for the project) must apply to "the department" for an exemption certificate, and the department must issue the certificate if the sponsor qualifies. The sponsor must give the seller the department-prescribed certificate, which is effective on the date the department receives the application; sellers must retain a copy. The certificate expires when the project is "certified as operationally complete," the sponsor must notify the department when that occurs, and the sponsor must pay any tax due within 60 days of expiration to avoid penalties and interest. The department may require periodic documentation to track total tax-exempt amounts. The bill also states that RCW 82.32.805 and 82.32.808 do not apply to this act. Key defined terms in the bill include "operationally complete," "qualified salmon recovery project," "qualified salmon recovery project sponsor," and what it means for property or services to be "received." The text provided does not identify which specific agency is meant by "the department," does not specify who formally certifies a project as operationally complete beyond the phrase used, does not define what counts as state funding for sponsor eligibility, and does not give the exact form or documentation requirements or explain the practical effect of excluding RCW 82.32.805 and 82.32.808.

If enacted, projects that qualify as salmon recovery work and have received state funding would not pay Washington sales or use tax on the labor, services, materials, equipment, and other tangible property that become part of the project, provided the project sponsor obtains an exemption certificate from the unnamed state department. The exemption begins on the date the department receives the application (but not for property or services received before August 1, 2025), and ends when the project is declared operationally complete; after expiration the sponsor has 60 days (or any extension) to pay any tax due without penalties or interest if paid in that window. The sponsors of these projects (private, public, or tribal entities with state funding) stand to reduce their project costs, potentially lowering the amount of other funding needed, but they must apply for the certificate, notify the department when the project is operationally complete, and may owe tax if the project’s status changes. Sellers must retain copies of exemption certificates or risk exposure if later challenged. The state tax department will lose some revenue for qualifying projects and will need to issue certificates and collect reporting to track exempted amounts. Important details remain unclear from the text provided: which specific department administers the program, how “state funding” and “certified as operationally complete” are defined, and exactly what documentation the department will require.
