The average cost of workers’ compensation insurance in Washington for 2026 will go up 4.9 percent.
According to the Washington State Department of Labor and Industries, starting January 1st, employers and workers together will pay, on average, $1.37 a week more for each full-time position. Employers pay about 75 percent of the premium, and workers pay about 25 percent.
The 4.9 percent increase is an average for all industries. The rate for specific industries could be higher or lower, depending on their recent history of injuries that led to claims.
Employers and workers in Washington pay into the workers’ compensation system to help cover the cost of providing wage and disability benefits for injured workers, as well as medical treatment for workplace injuries and illnesses.
Approval of the final rates followed three public hearings in late October.
