The Governing Committee of the Workers’ Compensation Insurance Rating Bureau of California voted to authorize the WCIRB to submit a September 1, 2026, pure premium rate filing to the California Insurance Commissioner proposing advisory pure premium rates that will be on average 10.4% above the average approved September 1, 2025 advisory pure premium rates.
The proposed advisory pure premium rates are based on insurer losses and loss adjustment expenses incurred during accident years 2025 and prior.

WCIRB Executive Vice President and Chief Actuary Tony Milano noted that the more notable drivers of the change were increased frequency of cumulative trauma claims as well as higher medical costs and allocated loss adjustment expenses.
The WCIRB expects to submit its filing to the CDI by the end of April. The CDI will schedule a public hearing to consider the filing.
