Workers Compensation Insurance in California

Workers’ compensation insurance is a crucial aspect of any business operation, ensuring that employees are protected in case of work-related injuries or illnesses.

This article provides an in-depth look at workers’ compensation insurance in California, detailing who needs it, how to obtain it, and the legal ramifications of not having it.

Workers Compensation Insurance in California

What is Workers’ Compensation Insurance?

Workers’ compensation insurance is designed to cover the costs associated with work-related injuries or illnesses. This includes medical expenses, lost wages, and rehabilitation costs. In California, every business that employs workers must carry this insurance, regardless of the number of employees.

Why is Workers’ Compensation Insurance Necessary?

Workers’ compensation insurance serves a dual purpose: it protects employees from financial hardship due to workplace injuries and shields employers from potentially devastating lawsuits. By ensuring that employees receive prompt medical attention and compensation for lost wages, workers’ compensation helps maintain a stable and productive workforce.

Who Needs Workers’ Compensation Insurance in California?

Mandatory Coverage for All Employers

In California, workers’ compensation insurance is mandatory for all employers, even if the business has only one employee. This requirement applies to all types of businesses, from large corporations to small startups.

Coverage for Out-of-State Employers

California law mandates that any business owner must carry workers’ compensation insurance for employees who regularly work in California, even if the company’s headquarters are located in another state. This ensures that all workers in California are protected under the state’s workers’ compensation laws.

Self-Employed and Independent Contractors

While self-employed individuals and independent contractors are not typically required to carry workers’ compensation insurance, certain types of contractors, such as roofing, tree service, and HVAC contractors, must have this coverage. Even for those who are legally exempt, it is advisable to consider purchasing a policy. Injuries that occur during work-related activities may not be covered by personal health insurance, leaving the individual responsible for medical bills and lost wages.

Part-Time Employees

In California, workers’ compensation coverage is required for all employees, regardless of the number of hours worked. This means that part-time and seasonal workers are entitled to the same protections as full-time employees.

How Much Does Workers’ Compensation Insurance Cost in California?

Factors Affecting Premiums

The cost of workers’ compensation insurance in California varies based on several factors, including:

  • Payroll: Higher payrolls typically result in higher premiums.
  • Location: Premiums can vary depending on the location of the business, such as Los Angeles versus San Diego.
  • Number of Employees: More employees mean a higher risk of claims, which can increase premiums.
  • Industry and Risk Factors: High-risk industries, like construction, tend to have higher premiums.
  • Coverage Limits: Policies with higher coverage limits will cost more.
  • Claims History: A history of frequent or severe claims can lead to higher premiums.

Average Cost

On average, businesses in California pay around $62 per month for workers’ compensation insurance. However, this amount can vary significantly based on the factors listed above.

How to Obtain Workers’ Compensation Insurance in California

Purchasing Options

There are three primary ways to obtain workers’ compensation insurance in California:

Private Insurance Carrier: Businesses can purchase workers’ compensation insurance from private insurance carriers. Platforms like Insureon allow businesses to compare quotes from top-rated insurers.

State Fund: California operates a competitive state fund, StateFund First, which provides workers’ compensation insurance.

Self-Insurance: Larger employers with at least three years in business and the financial ability to cover potential claims can apply for approval to self-insure through the Office of Self-Insurance Plans (OSIP).

Steps to Purchase Insurance

Evaluate Your Business Needs: Consider factors like the number of employees, industry risk, and payroll.

Compare Quotes: Use online tools or consult with insurance brokers to get multiple quotes.

Select a Policy: Choose a policy that offers the best balance of coverage and cost.

Implement Safety Programs: Establish workplace safety programs to reduce the risk of injuries and potentially lower premiums.

How to Save Money on Workers’ Compensation Insurance

Accurate Employee Classification

Correctly classifying employees based on their job duties is crucial. Employees with desk jobs or other low-risk positions generally cost less to insure than those in high-risk roles. Misclassification can lead to fines and increased premiums.

Pay-As-You-Go Insurance

Some small businesses can benefit from pay-as-you-go workers’ compensation insurance. This type of policy allows businesses to pay premiums based on actual payroll rather than estimates, which can be advantageous for businesses with seasonal or fluctuating employee numbers.

Safety Programs

Implementing a documented safety program can lead to fewer workplace accidents, reducing claims and potentially lowering insurance premiums. Regular safety training and workplace assessments can help maintain a safer work environment.

How Does Workers’ Compensation Work in California?

Benefits Provided

California’s workers’ compensation insurance provides a range of benefits, including:

  • Medical Care: Covers all medical expenses related to the injury or illness.
  • Temporary Disability Benefits: Provides partial wage replacement while the employee is recovering and unable to work.
  • Permanent Disability Benefits: Compensates employees if they suffer a permanent disability due to a work-related injury.
  • Supplemental Job Displacement Benefits: Offers vouchers for retraining or skill enhancement if the employee cannot return to their previous job.
  • Return-to-Work Supplement: Additional payments to help workers transition back to employment.
  • Death Benefits: Provides financial support to the dependents of workers who die due to work-related injuries or illnesses.

Claims Process

The claims process in California is designed to be straightforward. When an injury occurs, the employee should report it to the employer as soon as possible. The employer then files a claim with their workers’ compensation insurance provider, who will assess the claim and provide the necessary benefits.

Dispute Resolution

Most workers’ compensation claims are resolved without issue. However, disputes can arise. The California Division of Workers’ Compensation (DWC) Information and Assistance Unit provides resources and support to help resolve these disputes. If necessary, disputes can be taken to the Workers’ Compensation Appeals Board for a formal resolution.

Legal Consequences of Not Having Workers’ Compensation Insurance

Criminal Penalties

Failure to carry workers’ compensation insurance in California is a criminal offense. Penalties include:

  • Stop Order: A stop order can be issued to the business, and violating this order can result in fines up to $10,000 and imprisonment for up to one year.
  • Liens: The Uninsured Employer’s Benefit Trust Fund can file a lien against the employer’s property to recover benefits paid to an injured worker.
  • Fines: The Division of Labor Standards Enforcement can impose fines twice the amount the employer would have paid in premiums or $1,500 per employee during the period of non-insurance.
  • Additional Penalties: If a worker is injured and the employer does not have workers’ compensation insurance, additional penalties include $10,000 per employee at the time of injury for compensable cases or $2,000 per employee for non-compensable cases, with a maximum penalty of $100,000.

Civil Liabilities

In addition to criminal penalties, employers without workers’ compensation insurance may face civil liabilities. They can be sued by the injured employee for medical expenses, lost wages, and other damages, which could result in substantial financial losses.

How do I calculate workers’ compensation premiums?

Calculating workers’ compensation premiums involves several steps. Here’s a simplified overview:

Classification: Determine the classification code for each job role in your organization. These codes represent the type of work performed (e.g., clerical, construction, etc.).

Payroll: Calculate the total annual payroll for each job classification. This includes wages, salaries, bonuses, and other compensation.

Rate: Obtain the workers’ compensation rate for each classification code. Rates are typically expressed per $100 of payroll.

Premium Calculation:

  • Multiply the total payroll for each classification by the corresponding rate.
  • Sum up the premiums for all classifications to get the total premium.

The formula for calculating the premium is:

Premium=(100Payroll​) ×Rate

Remember that specific rules and adjustments may apply based on your state, industry, and insurer. Consult with an insurance professional for precise calculations tailored to your situation.


Workers’ compensation insurance is an essential component of running a business in California. It protects employees from the financial impact of work-related injuries and illnesses while shielding employers from costly lawsuits. By understanding the requirements, costs, and benefits of workers’ compensation insurance, California business owners can ensure they are compliant with the law and provide a safe and secure working environment for their employees.

Maintaining proper coverage, accurately classifying employees, implementing safety programs, and understanding the claims process are all crucial steps in managing workers’ compensation effectively.
