1. Introduction to Workers' Compensation Insurance in California

Workers' compensation insurance is a legal necessity for businesses in California. If you’re an employer or an employee, understanding this system can help you avoid legal pitfalls and financial hardships. This guide will give you a complete view of how workers’ comp works in California for 2025.

1.1 What is Workers' Compensation?

Workers' compensation is an employer-paid insurance that provides wage replacement and medical benefits to employees who get injured or ill due to their job. In California, it is governed by the California Division of Workers’ Compensation (DWC).

1.2 Why It's Required in California

California law mandates that every employer—even with only one employee—must carry workers' compensation insurance. Non-compliance can result in severe fines, criminal charges, or even imprisonment.

2. Who Needs Workers' Comp Insurance in California?

2.1 Employers

If you employ anyone in California—whether full-time, part-time, or temporary—you must carry workers' comp. This includes:

• Corporations with employees

• LLCs with employees

• Sole proprietors hiring help

2.2 Independent Contractors

Usually, independent contractors aren't covered. However, California's AB5 law uses a strict “ABC Test” that can classify contractors as employees, making the employer responsible for workers' comp.

3. What Does Workers' Comp Cover?

3.1 Medical Expenses

Covers all costs related to injury or illness treatment, including:

• Hospital visits

• Surgeries

3.2 Lost Wages

Injured employees receive a portion of their lost income during recovery.

If the employee can’t fully recover, permanent disability benefits are available.

3.4 Death Benefits

In case of death, workers' comp pays benefits to the employee’s dependents.

4. California Workers' Comp Rates (2025)

Large businesses may apply to self-insure, but it requires certification and proving financial strength.

Correct job classification is crucial. For example:

• “Clerical office” is far cheaper than “field technician”

• Reclassify roles annually if duties change

Your EMR reflects claim history. Tips to keep it low:

• File claims promptly and accurately

• Settle small claims quickly

• Avoid fraudulent or exaggerated claims

Use this checklist to ensure full workers' comp compliance:

Yes. Even if you have only one part-time or full-time worker in California, you must carry a workers' comp policy.

No. General liability does not cover employee injuries. Workers’ compensation is a separate legal requirement in California.

Not in most cases. If a family member is on payroll, they are considered employees and must be covered unless you're a sole proprietor with no employees.

22.4 What Happens If I Cancel My Policy Mid-Year?

Cancellation triggers a final audit. If underpayment is found, you will be billed the balance. Coverage lapse also exposes you to legal risks and fines.
