California Labor Code Section 3700 requires every employer in the state to carry workers’ compensation coverage from the moment they hire their first employee. There is no small-business exemption, no waiting period, and no minimum payroll. The only entity the statute exempts by name is the state itself. Skip the coverage and you face stop orders that shut down operations on the spot, civil penalties that can reach $100,000, misdemeanor prosecution, and personal liability for every dollar an injured worker is owed.
Who Has to Carry Coverage
The mandate is broad. If you employ even one person in California, you owe workers’ compensation coverage. Full-time, part-time, temporary, and seasonal workers all count.1California Legislative Information. California Code Labor Code 3700 – Insurance and Security The statute exempts the state government, including California’s superior courts, and no one else in that category. Cities, counties, and other political subdivisions are on the hook: they either buy insurance or go through a separate process to self-insure under subdivision (c).
The system is no-fault. An injured employee does not need to prove the employer did anything wrong. If the injury or illness arose out of work, benefits are owed. In return, an insured employer normally gets exclusive-remedy protection, meaning the employee cannot sue in civil court for additional damages. That protection disappears the moment coverage lapses, and the financial consequences are severe.
How to Comply
Private employers have two lawful paths under Section 3700. Most take the simple one: buy a policy from a licensed workers’ compensation insurer authorized to write in California.1California Legislative Information. California Code Labor Code 3700 – Insurance and Security The State Compensation Insurance Fund, a nonprofit insurer established by the legislature, is one option.2California Department of General Services. State Compensation Insurance Fund Claims – 8492 Employers turned down by standard carriers, often because of claims history or high-risk work, can obtain coverage through the assigned risk pool.
The second path is self-insurance, which means paying claims directly out of your own reserves. It is only realistic for financially strong organizations. You must apply through the Office of Self-Insurance Plans, produce at least three years of audited financials, hold an acceptable credit rating, post a security deposit that renews annually, and obtain a Certificate of Consent to Self-Insure from the Director of Industrial Relations.3Department of Industrial Relations. Office of Self-Insurance Plans – Overview and Requirements for Becoming Self-Insured Public entities have a parallel self-insurance option under subdivision (c) and often pool together through joint powers agreements.1California Legislative Information.

The Misclassification Trap
One of the most common ways employers end up out of compliance is by treating workers as independent contractors when the law treats them as employees. What you call the worker in a contract does not decide the question. California applies the ABC test, codified through AB5. A worker is presumed to be an employee unless the hiring entity can prove all three prongs:4LWDA. ABC Test
- The worker is free from the hiring entity’s control and direction in performing the work, both under the contract and in practice.
- The worker performs work that falls outside the usual course of the hiring entity’s business.
- The worker is customarily engaged in an independently established trade or business of the same nature as the work being performed.
Fail any single prong and the worker is your employee for workers’ compensation purposes. Employers who get this wrong have been operating uninsured without knowing it, which exposes them to every enforcement mechanism below.
Stop Orders and Civil Penalties
When the Director of Industrial Relations finds an employer without coverage, the response is immediate: a stop order that prohibits any use of employee labor until coverage is in place.5California Legislative Information. California Code Labor Code 3710.1 – Stop Order Operations halt on the spot. Ignoring a stop order is a separate misdemeanor carrying up to 60 days in county jail, a fine up to $10,000, or both.6California Legislative Information. California Code Labor Code 3710.2 – Stop Order Violation
Alongside the stop order, the Director issues a penalty assessment under Labor Code 3722. The amounts escalate with the situation:
- Employer caught uninsured: $1,500 per employee on the payroll at the time of the stop order.
- Uninsured for more than one week: the greater of $1,500 per employee or double the premium the employer should have been paying during the uninsured period. This replaces the base penalty rather than adding to it.
- An employee files a claim later found not compensable: $2,000 per employee on the payroll at the time of the injury.
- An employee files a claim found compensable: $10,000 per employee on the payroll at the date of injury.
The total penalty under Section 3722 caps at $100,000, with one exception: the “double the premium” calculation in the second tier has no cap.7California Legislative Information. California Code Labor Code 3722 – Uninsured Employers Fund A large employer who has dodged coverage for a long stretch can be assessed well into six figures.
Criminal Penalties
Operating without workers’ compensation is a misdemeanor under Labor Code 3700.5. A first conviction carries up to one year in county jail, a fine of up to double the premium that should have been paid (but not less than $10,000), or both.8California Legislative Information. California Code Labor Code 3700.5 – Insurance and Security The statute requires that the defendant knew, or reasonably should have known, about the obligation. For a business owner, that knowledge is essentially presumed.
A second or subsequent conviction is harsher: up to one year in county jail, a fine of triple the unpaid premium with a floor of $50,000, or both.9California Legislative Information. California Code LAB 3700.5 – Failure to Secure Compensation These criminal penalties stack on top of the civil penalties under Section 3722, not in place of them.
What You Owe an Injured Worker
Fines are only part of the exposure. If a worker is injured while your coverage has lapsed, you are personally liable for the full cost of every workers’ compensation benefit owed: medical treatment, temporary and permanent disability, supplemental job displacement benefits, and death benefits for dependents. Labor Code 4554 then adds a 10% penalty increase to every dollar of that compensation, treating the failure to carry coverage as automatic evidence of willfulness.10California Legislative Information. California Code Labor Code 4554 – Willful Failure to Secure Payment of Compensation
The bigger danger is the loss of exclusive remedy. An insured employer is shielded from civil suits by injured employees because workers’ compensation is the sole recourse. Labor Code 3706 strips that shield from an uninsured employer entirely. The employee can bypass the workers’ compensation system and sue for full civil damages, including pain and suffering, as if the workers’ compensation law did not exist.11California Legislative Information. California Code Labor Code 3706 – Failure to Secure Payment
The civil case is stacked against the employer from the start. Labor Code 3708 presumes that the injury resulted from the employer’s negligence, and the employer carries the burden of proving otherwise. The usual defenses — contributory negligence, assumption of risk, and fellow-servant negligence — are all unavailable.12California Legislative Information. California Code Labor Code 3708 – Presumption of Negligence A serious workplace injury tried under these rules can produce a judgment far larger than anything the workers’ compensation system would have paid.
The Uninsured Employers Benefits Trust Fund and Shareholder Liability
When an uninsured employer fails to pay benefits ordered by the Workers’ Compensation Appeals Board, the Uninsured Employers Benefits Trust Fund pays the injured worker directly so the worker is not left empty-handed because of the employer’s illegal choice.13Division of Workers’ Compensation. Uninsured Employers Benefits Trust Fund and Subsequent Injuries Benefits Trust Fund
The state then recovers the money from the employer. Under Labor Code 3715, once the Director determines an employer was illegally uninsured, a lien can attach to the employer’s property, to any parent corporation’s property, and to the personal property of substantial shareholders of a corporate employer.14California Legislative Information. California Code Labor Code 3715 – Uninsured Employers Benefits Trust Fund Incorporating does not put a clean wall between the business and the owner here. The statute reaches through the corporate structure to individuals with significant ownership, which is where the personal financial risk of skipping coverage becomes very real.
