California Workers Compensation Insurance Requirements Explained

Key Requirements Unique to California

California law mandates that every employer with at least one non‑exempt employee must carry workers compensation insurance, regardless of payroll size. The state's strict "no‑fault" system means benefits are paid to injured workers without proving employer negligence, and the California Department of Industrial Relations (DIR) oversees compliance.

Coverage Thresholds and Payroll Limits

Unlike many states that set a minimum payroll threshold, California imposes the insurance requirement on any employer with a single covered worker. Even seasonal or part‑time staff trigger the obligation. However, certain categories—such as sole proprietors with no employees and certain agricultural workers—may be exempt.

Types of Acceptable Policies

Employers can satisfy the requirement by purchasing a policy from a licensed private insurer, obtaining a self‑insurance certificate from the DIR, or joining the State Compensation Insurance Fund (SCIF), a quasi‑public carrier that provides coverage to high‑risk or uninsured firms.

Employer Responsibilities

Once coverage is secured, employers must:

• Post the official Workers Compensation Notice in a conspicuous area.
• Provide new hires with a claim form within 30 days of employment.
• Report workplace injuries to the employer's insurance carrier and the DIR within five days.
• Maintain accurate payroll records for at least three years.

Filing and Claims Process

When an injury occurs, the employee completes a DWC‑1 claim form, which the employer forwards to the insurer. The insurer then investigates, determines eligibility, and issues benefits covering medical care, temporary disability wages, and, if applicable, permanent disability.

Penalties for Non‑Compliance

Failure to maintain required coverage can result in:

• Daily fines ranging from $100 to $1,000 per uncovered employee.
• Potential civil lawsuits for unpaid benefits.
• Inability to claim workers compensation benefits for injured staff.
