Whether you are an employee, HR professional, or compliance leader, this post provides an up-to-date summary of significant developments in Washington state employment law you need to know.
As of October 2025, Washington employers and HR professionals should pay particular attention to the expanded tax obligations for staffing and service-providers (ESSB 5814), ensure adherence to the new minimum wage levels, and confirm that background-check and sick-leave policies reflect the mid-2025 employment law changes.

Expanded Sales/Staffing Services Tax — Legislation
Date: October 1, 2025
Summary:
Under ESSB 5814, effective October 1 2025, Washington expands its retail sales tax regime and Business & Occupation (B&O) excise tax to cover service categories previously exempt. These services now subject to tax include IT support, software customization, advertising/marketing services, live presentations (e.g., paid webinars, workshops), and crucially for labor/employment law, temporary staffing and security services.
Implications:
For staffing agencies, HR service providers, and employers using contract or temporary workers in Washington, this law may increase cost burdens and require adjustments to billing, classification, and cost-pass-through practices. Employers should review vendor contracts and service agreements to understand whether cost increases (or reclassification of services) will impact workforce engagements.
Minimum Wage & Wage Disclosure – General Update (Effective Jan 1, 2025)
Date: January 1, 2025 (but relevant as background for Oct 2025 compliance)
Summary:
The Washington State Department of Labor & Industries announced that the state’s minimum wage will increase to $16.66 per hour, up 2.35 % from 2024. Employers may pay 85 % of that ($14.16/hour) to workers ages 14-15.
Implications:
Although this change took effect January 1, it remains an essential compliance baseline for October 2025 payroll and audits. Employers in Washington should ensure all wage schedules, job postings, contracts, and payroll systems are aligned with the correct minimum wage figures, and that any youth worker provisions are properly applied.
Key Employment Law Changes Effective July 27, 2025 (Still Operational in Oct)
Date: July 27, 2025 (effective date)
Summary:
Several major employment law changes took effect mid-2025, which continue to shape the labor landscape in October. These include:
- Expansion of the Fair Chance Act: Under HB 1747, for employers of 15+ employees, inquiries into criminal history must now wait until after a conditional offer. Blanket exclusions are prohibited.
- Expansion of the Paid Sick Leave Act: Under HB 1875, employees may use accrued sick leave to prepare for or attend immigration proceedings for themselves or family members.
- Introduction of a “mini-WARN”-type Act: Employers now face new requirements for advance notice of certain workforce reductions in Washington.
Implications:
Though these changes are not new for October, they are now fully live and warrant attention in HR policy audits, job-posting processes, employee handbooks, and workforce planning. Employers in Washington should ensure that background check procedures, sick-leave policies, and lay-off/closure protocols reflect the current law.
