As a policyholder, you may recognize that there are some California Workers’ Compensation Premium Assessment Rate changes. In 2022, policyholders can expect to see a significant increase in their California Premium Assessment rates, which is independent of their Workers’ Comp rates.

The CA Workers’ Comp Premium Assessment has increased to cover California’s Division of Workers’ Compensation’s budget and provide a source of stable funding for related administration and programs. Surcharge programs are required by law for all California Insurance Carriers to participate in. As an insured, you must be aware of these changes. Here is what you need to know:

  • The total percentage for all the premium assessments in 2021 was 3.959%. Effective 1/1/22 the new rates will total 5.9318%.
  • On accounts that rates remain “flat”, the insured will still see a 2% increase due to the large increase in the California premium assessment rates.
  • California premium assessments are applied to all Workers’ Comp policies issued in California, regardless of loss history and independent of workers’ comp rates which continue to remain at an all-time low.

 Surcharge/Assessment 1/1/2022 1/1/2021
