The bill amends existing public works prevailing wage law (RCW 39.12.010 and RCW 39.12.120) to add and change recordkeeping, filing, and definitional requirements. It requires contractors, subcontractors, or employers on public works to keep accurate payroll records for three years from the date the contract awarding agency accepts the project, and to file certified payroll records at least monthly using the Department of Labor and Industries (L&I) online system or, if not using the online system, directly with L&I in an approved format. L&I must provide, upon request, a copy of an employer’s certified payroll records to an “interested party.” Noncompliance with the payroll-records section is treated as a violation of RCW 39.12.050. The bill also limits how payroll information provided to joint labor-management cooperation committees may be used: only for filing complaints under RCW 39.12.065 and not for union organizing or commercial activity. It clarifies payment timing (wages other than usual benefits must be paid at least monthly; usual benefits must be paid by their regularly established deadlines) and makes multiple definitional changes and additions (including “prevailing rate of wage,” “locality,” “usual benefits,” “interested party,” “inadvertent filing or reporting error,” “unpaid prevailing wages,” “rate of contribution,” and a broadened definition of “contractor” to include entities with substantially identical operations or structure under certain nonexclusive factors). The amendments modify existing law (procedural and definitional changes) rather than creating a new crime or new penalty scheme; failure to comply is linked to an existing violation provision. Section 1 of the act expires January 1, 2026, and Section 2 takes effect January 1, 2026. The extract does not show the full bill or explain the relationship between the two separate amendments to RCW 39.12.010 beyond those dates, so the broader legislative context and any other provisions outside the displayed sections are not available here.

If enacted, contractors, subcontractors, and other employers on public works will have to keep accurate payroll records for three years from the agency’s acceptance of the project and file certified payroll at least once a month using L&I’s online system (or directly to L&I in an approved format). Employers must pay cash wages at least monthly and usual benefits by their regular deadlines. The Department of Labor and Industries must provide copies of certified payroll to defined “interested parties” on request, but joint labor‑management cooperation committees may only use payroll information to file complaints and may not use it for union organizing or commercial purposes. Failing to comply with the payroll-records rules is treated as a violation of state prevailing wage law. The practical burden falls most heavily on contractors and subcontractors, who will face higher ongoing administrative duties, potential costs to comply with monthly certified filings, and greater exposure to enforcement if related corporate entities are treated as the same “contractor” under the broadened definition of substantial identity. L&I will take on expanded record-handling and disclosure duties. Workers and organizations gain clearer access to payroll data to support enforcement of prevailing wages. The provided text leaves unclear how the two staggered sections (one expiring January 1, 2026 and one taking effect that same date) are intended to interact.
