What are Self-Insurance Assessments?

A self-insured employer pays assessments to L&I based on the information reported in their Quarterly Report. These assessments help to fund the Self-Insurance Program, provide resources to self-insured employers, and create reserves in circumstances of default.

Supplemental Pension Fund and Asbestosis Fund

What are Supplemental Pension Fund and Asbestosis Fund Assessments?

Pay During Appeal Overpayment Fund

What is a Pay During Appeal Overpayment Fund?

  • This fund is used to reimburse self-insured employers for benefits provided when the outcome of an appeal process results in an overpayment of benefits to an injured worker. If a self-insured employer is unable to fully recover the overpayment, they can receive support from this fund two years after they first attempted to collect the overpayment from the injured worker.
  • The assessment is based on worker hours.
  • The rate is determined on a calendar year basis.
