The State Compensation Insurance Fund (State Fund) is a public enterprise fund established to provide California businesses with an available market for workers' compensation insurance while making California's workplaces safer and helping injured employees return to work. The State Fund operates on premiums written and investment income and is self-supporting.

The State Fund, under a Master Agreement with the Department of Personnel Administration, provides workers' compensation claims administration services for legally uninsured state agencies. Under this agreement state agencies reimburse the State Fund for benefit payments made to injured workers and health care providers as identified in the Workers' Compensation Benefits for State Agencies budget display.
