The commissioner issued a decision on July 10, approving advisory pure premium rates for new and renewal policies effective on or after September 1, 2026. The approved advisory pure premium rates average $1.65 per $100 of payroll.
The WCRIB’s proposed advisory pure premium rates are based on insurer losses and loss adjustment expenses incurred during accident years 2025 and prior. According to the WCIRB, drivers of the change include increased frequency of cumulative trauma claims as well as higher medical costs and allocated loss adjustment expenses.
