Workers’ Compensation Benefits Are Regulated By Which Entity?

The California Agencies That Regulate Workers’ Compensation

Several state bodies with different responsibilities handle California’s workers’ compensation system. For example, the Division of Workers’ Compensation monitors the administration of workers’ compensation claims and helps resolve disputes. The Workers’ Compensation Appeals Board reviews certain decisions that workers’ compensation judges have made.

The Department of Industrial Relations

The California Department of Industrial Relations oversees the state’s workers’ compensation system. It is the parent department of the Division of Workers’ Compensation and the Workers’ Compensation Appeals Board.

Through these bodies, DIR oversees the administration of workers’ compensation claims, resolves disputes, and administers parts of the benefits system. It also manages certain special funds that may apply in cases involving uninsured employers.

DIR publishes information and reports about California’s workers’ compensation system. You can review this material through the Commission on Health and Safety and Workers’ Compensation’s annual reports.

The Division of Workers’ Compensation

The Division of Workers’ Compensation monitors the administration of workers’ compensation claims and provides administrative and judicial services to resolve disputes over workers’ compensation benefits. When your claim is denied, delayed, or disputed, the DWC is where the formal process begins.

Here is how the DWC fits into your claim:

• Your employer must provide a DWC-1 claim form within one working day after learning of an injury that causes lost time beyond your current work shift or requires medical treatment beyond first aid. Completing the employee section and returning it to your employer officially opens your claim.
• DWC workers’ compensation judges adjudicate disputed claims.
• If you are unrepresented, the DWC’s Information and Assistance Unit can help you navigate the process or file a formal Application for Adjudication. It can be reached at 1-800-736-7401.

Most formal disputes about workers’ compensation benefits are handled within the DIR/DWC adjudication system, with hearings before workers’ compensation judges and review by the WCAB. The California Department of Insurance and your employer’s HR department do not adjudicate workers’ compensation benefit disputes.

The Workers’ Compensation Appeals Board

If you receive a decision from a DWC administrative law judge that you disagree with, you may be able to petition the Workers’ Compensation Appeals Board for reconsideration. The WCAB is a seven-member judicial body. Its members are appointed by the Governor and confirmed by the Senate.

The WCAB reviews petitions for reconsideration of decisions by workers’ compensation judges. It also adopts rules of practice and procedure for adjudication. The WCAB generally reviews the record of the DWC proceeding rather than retrying the case. However, it may order further proceedings or allow additional evidence in certain circumstances, such as when newly discovered evidence is presented.

Missing important evidence at the administrative level can still limit your options on review. That makes it important to build a complete record before the workers’ compensation judge. Building the evidentiary record early can help preserve evidence for a workers’ compensation appeal.

The Office of Self-Insurance Plans

The Office of Self-Insurance Plans (OSIP), a program within the DIR Director’s Office, authorizes and regulates self-insured employers and groups of employers. Not every employer purchases a workers’ compensation insurance policy. California allows qualifying employers and groups of employers to self-insure their workers’ compensation obligations instead.

OSIP reviews applications, requires ongoing security deposits to protect injured workers if a self-insurer defaults, and audits self-insurers’ claims-handling and reserving practices. According to DIR’s 2025 statistics, roughly 1 in 8 California workers are covered through workers’ compensation self-insurance, placing a substantial share of the workforce under OSIP’s oversight.

The California Laws That Govern Workers’ Compensation

The California Labor Code is the primary law governing workers’ compensation rights and responsibilities in the state. It covers issues such as employer coverage requirements, employee definitions, benefits, and the dispute process handled through the DWC and WCAB.

Some key provisions include:

• Labor Code § 3700: Requires employers to secure workers’ compensation coverage.
• Labor Code §§ 3600–3602: Set out important rules on compensable injuries and the workers’ compensation system’s exclusive remedy provisions.
• Labor Code § 5405: Sets limitation periods for commencing proceedings to collect workers’ compensation benefits.

Other Labor Code provisions apply to state employees and certain other categories of workers. An attorney can help determine which rules apply to your situation.

When Federal Workers’ Compensation Laws Apply in California

Federal workers’ compensation laws apply to certain employees and industries in California. The state system covers most workers, but federal employees and some maritime workers may fall under federal law instead.

• Federal Civilian Employees: Federal civilian employees are generally covered by the Federal Employees’ Compensation Act (FECA). The U.S. Department of Labor’s Office of Workers’ Compensation Programs (OWCP) administers FECA. This includes workers at federal agencies such as the U.S. Postal Service. For covered federal employees, FECA generally provides the exclusive workers’ compensation remedy for a work-related injury.
• Maritime Workers: Some workers involved in loading, unloading, shipbuilding, ship repair, and similar maritime work may be covered by the Longshore and Harbor Workers’ Compensation Act (LHWCA). In some cases, both the LHWCA and California workers’ compensation law may apply. Benefits paid under one system can reduce what is owed under the other.

It may not always be obvious which system applies. Filing under the wrong system can cause delays or missed deadlines. A workers’ compensation attorney can help determine which law applies to your claim.

The Role of the California Department of Insurance

The California Department of Insurance regulates the insurance companies that provide workers’ compensation coverage. Coverage requirements can depend on worker classification and the type of business entity.

The CDI’s role includes:

• Rate oversight. Workers’ compensation insurers must file their rates and related rating information with the CDI before using them. California uses an open rating system. The CDI reviews insurer rates and helps oversee the financial stability of the insurance market.
• Insurer licensing and financial oversight. The CDI licenses insurance companies, monitors their financial condition, and may oversee conservation or liquidation if an insurer becomes insolvent.
• Fraud investigation. The CDI investigates workers’ compensation insurance fraud, including fraudulent claims activity. Suspected fraud can be reported to the California Department of Insurance’s Fraud Division.

One Important Distinction: Most disputes between injured workers and workers’ compensation insurers do not fall under the CDI’s jurisdiction. If your dispute involves a denied or delayed workers’ compensation claim or benefits, the DWC is generally the proper forum.

What if a Workers’ Compensation Insurer Becomes Insolvent?

If a workers’ compensation insurer becomes insolvent, the California Department of Insurance may step in through its Conservation and Liquidation Office. That office helps manage the insurer’s conservation or liquidation.

The California Insurance Guarantee Association (CIGA) may also become involved. CIGA can take over certain covered workers’ compensation claims from an insolvent insurer and continue eligible benefit payments, subject to California workers’ compensation law and CIGA’s statutory requirements.

This system helps protect injured workers when an insurance company is unable to meet its obligations.

What Happens When an Employer Fails to Carry Workers’ Compensation Insurance?

An employer who knowingly fails to secure required workers’ compensation coverage commits a misdemeanor. Under California Labor Code § 3700.5, a first offense may result in up to one year in county jail, a fine of up to twice the premium that would have been due during the uninsured period—but no less than $10,000—or both.

Separate civil penalties also apply under California Labor Code § 3722. Some penalties under that section are capped at $100,000, while others are calculated separately based on factors such as unpaid premiums or the number of employees.

If your employer was uninsured when you were injured, you are not without recourse:

• You can file a claim with the Uninsured Employers Benefits Trust Fund (UEBTF), which steps in to pay benefits when an employer is illegally uninsured and fails to pay compensation awarded by the WCAB.
• You may also be able to file a civil action against the uninsured employer in addition to the workers’ compensation claim.

If you are unsure whether your employer carried insurance on the date of your injury, the DWC Information and Assistance Unit at 1-800-736-7401 can point you to coverage verification resources.

Who Must Be Covered Under California Workers’ Compensation?

Workers’ compensation insurance must cover most employees in California if they suffer a work-related injury or illness arising out of and in the course of their employment. Coverage may depend on the person’s role, ownership interest, pay structure, and whether a valid waiver is available.

Workers who are generally covered include:

• Full-time employees.
• Part-time employees.
• Temporary and seasonal employees.
• Minors and undocumented workers.
• Apprentices and trainees.

Different rules may apply to certain business owners, officers, directors, partners, and LLC members under Labor Code §§ 3351 and 3352.

• Corporate Officers and Directors: Executive officers and directors of private corporations are generally covered when they perform actual services for the corporation for pay. Some may qualify for a coverage waiver if they meet the requirements under California law.
• LLC Members: A qualifying managing member may be able to waive workers’ compensation coverage. Other working LLC members who receive wages regardless of profits are generally treated as employees for workers’ compensation purposes.
• Sole Proprietors: A sole proprietor is generally not required to include themselves in workers’ compensation coverage, but may choose to obtain coverage.

The DWC or a qualified workers’ compensation lawyer can help determine whether a particular person must be covered or may validly waive coverage.

What Workers’ Compensation Benefits May Be Available?

If you are covered and suffer a qualifying work-related injury or illness, you may be eligible for several types of workers’ compensation benefits. The benefits available depend on the nature of your injury and how it affects your ability to work.

Common benefits may include:

• Medical Care: Treatment that is reasonably required to cure or relieve the effects of the work injury.
• Temporary Disability Benefits: Partial wage replacement if your injury prevents you from working while you recover.
• Permanent Disability Benefits: Payments if your injury causes lasting impairment.
• Supplemental Job Displacement Benefits: A voucher that may help pay for retraining or skill enhancement if you have a permanent partial disability and your employer does not offer qualifying work, subject to the applicable requirements.
• Death Benefits: Payments that may be available to qualifying dependents when a worker dies from a work-related injury or illness.

The type and amount of benefits can vary from one claim to another. A workers’ compensation attorney can help explain which benefits may apply to your situation.

Your Workers’ Comp Claim and a Third-Party Claim: Two Separate Tracks

Workers’ compensation is generally the exclusive remedy against your employer (Labor Code §§ 3600–3602). However, you may also have a separate civil claim if a legally responsible third party caused or contributed to your work injury (Labor Code § 3852).

Understanding the difference between workers’ compensation claims and injury claims is important because each follows a separate legal process. Examples of a third negligent party may include:

• A driver.
• A product manufacturer.
• A property owner.

These claims are separate legal tracks. They have different procedures, deadlines, and remedies.

• Workers’ Compensation Claim: You usually start the claim by reporting the injury and submitting the DWC-1 through your employer. If a dispute arises, you may need to file an Application for Adjudication of Claim with the DWC within the time limits set by Labor Code § 5405.
• Third-Party Civil Claim: You may also bring a personal injury claim against the legally responsible third party. For many private personal injury claims, California Code of Civil Procedure § 335.1 provides a two-year statute of limitations. If the third party is a government entity, an additional deadline may apply. Government Code § 911.2 generally requires a written government claim within 6 months of accrual for personal injury claims. Limited procedures for late-claim relief may be available in some cases.

Another issue is reimbursement. Your employer or its workers’ compensation insurer may have a lien against part of your third-party recovery for benefits already paid. Pursuing both claims simultaneously can, therefore, require careful coordination.

Arash Law has handled cases involving both workers’ compensation and personal injury claims. One of the cases we handled spanned both areas. Hence, the firm’s personal injury and workers’ compensation teams worked together and secured a $9,855,000 recovery for the client just 5 days before trial.

A personal injury attorney who also handles workers’ compensation cases can help determine which claims apply and how the two cases may affect each other. See more of our case results.

Note: Outcomes depend on the unique facts of each case, and past results do not guarantee similar results in any future case.

Frequently Asked Questions About Workers’ Compensation Regulation

California workers’ compensation involves several agencies, coverage rules, and filing deadlines. These answers explain which entity handles each issue and what options may apply when a claim is disputed, an employer is uninsured, or another party caused the injury.

Does the California Department of Insurance Handle My Workers’ Compensation Claim?

No. Most disputes between injured workers and their workers’ compensation insurers fall under the jurisdiction of the DWC, not the CDI. The CDI primarily regulates insurer rates, licensing, and financial solvency.

If your claim is disputed and you are unrepresented, the DWC’s Information and Assistance Unit can help explain the process. The CDI also investigates workers’ compensation fraud, but that is separate from resolving your individual claim.

Who Is Required to Purchase Workers’ Compensation Insurance in California?

California employers generally must secure workers’ compensation coverage for their employees under Labor Code § 3700. Coverage rules can depend on worker classification, corporate structure, and other business-specific factors.

What Happens If My Employer Was Not Insured When I Was Injured?

If your employer was unlawfully uninsured, you may be able to file a claim with the UEBTF or pursue a civil action against the employer. Criminal and civil penalties may also apply to employers that fail to carry required coverage. See the Employer Insurance section above for more details.

What Is the Deadline to File a Workers’ Compensation Claim in California?

California Labor Code § 5405 generally requires proceedings to collect workers’ compensation benefits to begin within one year after the date of injury, the expiration of the period covered by certain disability payments, or the last date qualifying medical benefits were furnished. Other rules and exceptions may affect the deadline.

Can I Sue Anyone Other Than My Employer for a Work Injury?

Yes, in some cases. If a legally responsible third party caused or contributed to your injury, you may have a separate civil claim. Examples can include a negligent driver, an equipment manufacturer, or a property owner.

Workers’ compensation is generally the exclusive remedy against your employer under Labor Code §§ 3600–3602. A separate third-party personal injury claim may also be available. For many private personal injury claims, California’s two-year statute of limitations applies. Government claims and other specialized cases can have shorter or different deadlines.
