California Workers' Comp Requirements
California employers generally must provide workers' compensation when they have one or more employees. Limited exceptions exist for certain sole proprietors and family members depending on entity type and elections. Licensed contractors must carry coverage or file a valid exemption.
How Premium Is Calculated in California
Premium is primarily payroll per $100 times the class-code rate, adjusted by the experience modification and other factors. The WCIRB sets class codes and base rates, and calculates the experience mod.
Class Codes and the Experience Mod
Class codes categorize work by hazard; the experience mod adjusts premium based on your claims history versus similar businesses. Both are central to cost and to audit results.
