Introduction

This guide explains employer workers comp fraud California — what it is, how it harms injured workers, and the concrete steps to protect your rights. If you’re dealing with an employer not reporting work injury, misclassified workers and injury claims, a no workers comp insurance employer, or an under the table work injury, you are not alone.

Who this post is for: injured workers in California (including undocumented and under‑the‑table workers), family members, advocates, and intake staff at legal aid. Promise: Clear definitions, real scenarios, step‑by‑step immediate actions, agency contacts, and guidance on when to hire a lawyer. We’ll explain how to report misclassification and under the table work injury situations, and how to pursue benefits even when employers refuse to cooperate.

For a broader primer on benefits and the claims process, see our overview of what workers’ comp benefits cover and our step‑by‑step guide on how to file a workers’ compensation claim.

Quick Definitions

Employer workers’ compensation fraud is when a business intentionally misrepresents facts to avoid paying insurance premiums or providing benefits — not simple mistakes, but deliberate schemes to cut costs at workers’ expense. California’s enforcement overview explains common fraud patterns and consequences, including criminal exposure for employers who lie or conceal injuries to dodge claims (DWC Fraud Prevention overview; common types of workers’ comp fraud).

• Refusing to report injuries. Employers must promptly report work injuries; when they don’t, the insurer isn’t notified and medical care is delayed. This is a known fraud scheme that hides claims and keeps premiums artificially low (state fraud prevention guidance).

• Misclassification/premium fraud. Labeling employees as independent contractors or placing them in lower‑risk job classes to cut premiums is premium fraud. It often surfaces as misclassified workers and injury claims disputes when injuries occur (fraud types; LA County risk management fraud guidance).

• Operating without insurance. California requires employers to carry workers’ compensation insurance. Operating uninsured is illegal and can trigger prosecution and business shutdowns (Shasta County DA fraud page).

• Paying under the table. Cash pay with no payroll records or EDD reporting is part of the underground economy and often coincides with work injuries and denial of benefits (worker fraud guide).

• Pressuring you to accept cash or sign waivers. Some employers push quick cash or “no claim” waivers that strip you of benefits and erase the paper trail.

Throughout this guide, examples will cover all key problems: employer not reporting work injury, misclassified workers and injury claims, no workers comp insurance employer, and under the table work injury — the core ways employer workers comp fraud California shows up.

If you’re new to the system, our plain‑English introduction to California workers’ comp laws can help you get oriented.

California Legal Framework

Several agencies administer claims and enforce compliance:

• Division of Workers’ Compensation (DWC). Administers claims, benefits, and the DWC‑1 claim form (DWC homepage; DWC fraud prevention).

• Workers’ Compensation Appeals Board (WCAB). Hears disputes and issues orders (WCAB page).

• Department of Industrial Relations (DIR). State oversight and fraud prevention (DIR homepage).

• Labor Commissioner / DLSE. Enforces wage laws and misclassification cases (DLSE).

• Employment Development Department (EDD). Enforces payroll and tax reporting (EDD).

• California Department of Insurance. Investigates workers’ comp fraud (Department of Insurance).

• Local District Attorney fraud units. Prosecute criminal workers’ comp fraud, including example county resources (Shasta County DA workers’ comp fraud).

Importantly, undocumented and under‑the‑table workers are still entitled to medical care and workers’ compensation benefits if injured on the job; immigration status does not cancel those rights (Bosco Legal guide).

California’s AB5 framework uses the ABC test to fight misclassification. A worker is presumed to be an employee unless the employer proves ALL three: (A) free from control; (B) outside usual course of business; (C) customarily engaged in independently established trade. This test is central to reclassifying “contractors” who are actually employees (AB5/ABC test explanation).

Real‑World Scenarios

Scenario A — Employer Not Reporting Work Injury

Maria’s story. Maria hurt her back lifting boxes in a warehouse. Her supervisor told her to “rest at home” and promised some extra cash on her next paycheck, but never reported the injury. He discouraged her from seeing a doctor.

What should legally happen. The employer must provide a DWC‑1 claim form within one working day of learning about the injury and promptly report serious injuries to the insurer; all injuries must be reported within five days (county DA guidance on employer duties; state fraud prevention page).

What fraudulent employers do. An employer not reporting work injury hides the claim to avoid premium hikes and oversight, sometimes offering cash to keep quiet.

Consequences for the worker. No medical authorization, delayed care, and gaps in records that make proof harder later. Maria’s condition can worsen without timely treatment.

Immediate legal exposure for the employer. Penalties for failing to report and potential criminal charges for fraud; significant fines possible (Shasta County DA).

Quick action. Put notice in writing and request the DWC‑1 immediately. If ignored, file your claim yourself and seek medical treatment now.

Scenario B — Misclassified Workers and Injury Claims

Carlos’s story. Carlos worked full‑time on construction crews with a set schedule, employer tools, and supervision. After a fall from scaffolding, the company claimed he was an “independent contractor” and denied responsibility.

The law. Under the ABC test, Carlos is an employee unless the employer proves: (A) free from control; (B) outside usual course of business; (C) customarily engaged in independently established trade. Construction is the company’s core business and Carlos lacked independence, so misclassification likely fails (ABC test and misclassification).

What fraudulent employers do. They call injuries “not our problem” and push workers to use personal health insurance or forgo care.

Worker’s path forward. File the DWC‑1 and also a misclassification/wage complaint with DLSE. Evidence of control and integration supports reclassification and benefits (Bosco Legal guide).

Quick action. Gather proof of control (set hours, supervision, company tools) and report misclassification to the Labor Commissioner while your DWC claim proceeds.

Scenario C — No Workers Comp Insurance Employer

Jamal’s story. Jamal, a landscaper, sliced his hand on equipment and learned the employer had no insurance — a no workers comp insurance employer situation (DA fraud page).

The law. Operating without coverage is a misdemeanor punishable by up to one year in jail and a minimum $10,000 fine, plus stop‑work orders (Shasta DA).

Worker’s remedy. File a workers’ comp claim and pursue benefits through the Uninsured Employers Benefits Trust Fund (UEBTF). You may also have the rare option to sue the employer directly (LA County risk management; Shasta DA).

Quick action. File your claim right away and ask about UEBTF procedures. Learn how claims proceed when coverage is unclear in our guide on appealing denied workers’ comp claims.

Scenario D — Under the Table Work Injury

Rosa’s story. Rosa cleaned homes for cash without pay stubs. After a stairway fall injured her shoulder, the employer claimed she was never an employee — a classic under the table work injury problem (Bosco Legal guide).

The challenge. She must prove employment and wages without formal records.

Evidence that works. Scheduling texts, photos at job sites, bank deposits on regular “paydays,” witness statements from clients/co‑workers, and uniforms/tools provided by the employer can prove both the relationship and earnings (Bosco Legal guide).

Quick action. Collect digital evidence immediately and file a DWC‑1. For help documenting wages and benefits, see our overview on workers’ comp benefits.

Immediate Steps After an Injury

Act now — every minute matters. Early action protects your health and your claim, especially if your employer is uncooperative.

1. Seek medical care now. Tell the provider: “This injury occurred at work on [date] while I was [describe activity].” Medical records are primary evidence.

2. Notify your employer in writing immediately. Keep it short: “On [date] at approximately [time], I injured my [body part] while [describe task] at [location]. I am notifying you of this work injury and request the workers’ compensation claim form (DWC‑1) and carrier information. Please provide the DWC‑1 within one working day.” Save screenshots, emails, and texts.

3. Request the DWC‑1. If they refuse, download and file it yourself from the official DWC‑1 form page (see the DWC homepage). Learn the filing steps in our walkthrough on how to file a workers’ comp claim.

4. Preserve evidence. Take photos of the scene and injuries, screenshot communications, copy pay records, list witnesses with contact info, and save photos of tools/equipment.

5. Document wages/pay. Keep bank deposits, dated notes, and photos of cash receipts; maintain a pay journal showing dates and amounts — essential for under the table work injury cases.

6. Do NOT sign releases or accept cash “settlements.” These offers are designed to waive your rights.

7. If the employer resists or you fear retaliation, contact DLSE and an attorney. Anti‑retaliation protections are enforced by the Labor Commissioner (DLSE).

If your employer is not reporting the injury, or if there’s a no workers comp insurance employer, file on your own and preserve every piece of evidence. For more time‑sensitive guidance, review our explainer on the workers’ comp time limit to file.

Proving Employment & Wages

If formal records don’t exist, build a paper trail from indirect evidence. This is crucial for misclassified workers and injury claims and under the table work injury situations.

Direct evidence (why it helps). Contracts or offer letters, any pay stubs or checks, 1099s, timecards/schedules, uniforms or badges, training records, company emails/logins, and calendars show an employment relationship and schedule patterns (Bosco Legal guide).

Indirect evidence (how to present it). Screenshots of supervisor texts assigning tasks (with timestamps), GPS/phone location data at worksites, client records confirming dates worked, photos of you working, witness statements from co‑workers/clients, and bank deposit patterns on consistent days can together prove employment and wages (Bosco Legal guide).

Wage calculations when paid cash. Average pay using deposit records, your dated notes, client invoices, co‑worker statements, and industry rates. Use conservative rounding and keep a clear method to explain to a WCAB judge if asked.

Classification checklist (ABC test). In California, employee status is presumed unless the employer proves all three:

• A: Are you free from control and direction? Evidence: set schedule, supervision, mandatory procedures.

• B: Is the work outside the employer’s usual business? Evidence: your job is not integral to the company’s core services.

• C: Are you customarily engaged in an independent business? Evidence: your own advertising, business license, multiple clients.

Sample phrases to capture control: “You were told to be on site from X to Y,” “You used the company vehicle,” “You used company tools,” “A supervisor inspected and approved your work.” See more on misclassification proofs in this AB5/ABC test overview.

Reporting, Enforcement & Remedies

Report to multiple agencies — the same facts can trigger different enforcement tracks. Doing each step protects your claim and pushes the system to act.

1. File the DWC‑1 claim. Submit it to the insurer or file it yourself using the official DWC‑1 form. The DWC explains claim procedures and can help when your employer refuses to cooperate.

2. File a wage/misclassification complaint with DLSE. The Labor Commissioner can order back wages, penalties, and reclassification.

3. Report payroll/tax fraud to EDD. The EDD audits employers; its findings support misclassification and wage proof.

4. Report insurance fraud. Notify the California Department of Insurance Fraud Division and your local DA’s workers’ comp fraud unit (see examples: Shasta County, Riverside County).

5. If there’s no insurance, consider UEBTF. For a no workers comp insurance employer, the Uninsured Employers Benefits Trust Fund may pay benefits; DA and county risk guidance explain options (LA County risk management; Shasta DA).

What each agency can do. DWC/WCAB orders medical and wage benefits. DLSE fixes wages, classification, and retaliation. EDD assesses back taxes/penalties. The Department of Insurance investigates criminal fraud. District Attorneys prosecute.

Remedies for workers. You may receive medical treatment at no cost, temporary disability (typically two‑thirds of wages), permanent disability, vocational retraining, and death benefits where applicable (benefits overview). In serious and willful misconduct cases, judges can award penalty increases; UEBTF can step in when employers are uninsured (risk management; DA guidance).

Copyable scripts (short).

• To DWC: “I am filing a workers’ compensation claim for a work injury on [date]. My employer refused to provide the DWC‑1 and may be committing employer workers comp fraud California. I need guidance on filing and identifying the employer’s insurer.”

• To DLSE: “I want to file a misclassification/wage complaint. My employer calls me an independent contractor but controls my schedule and supplies tools.”

For step‑by‑step filing guidance and avoiding common mistakes, see our checklist on how to file a workers’ comp claim and tips for appealing a denial if needed.

Employer Penalties & Criminal Exposure

Premium fraud (felony). Up to five years in state prison and fines up to $50,000 for misrepresenting payroll, job class, or worker status to cut premiums (LA County risk management; Shasta DA).

Uninsured employer (misdemeanor). Up to one year in jail and minimum $10,000 fine; stop‑work orders can shut the business (Shasta DA).

Failure to report injuries. Employers who conceal injuries or fail to provide a DWC‑1 within required timeframes risk civil penalties and possible criminal prosecution (DWC fraud prevention; risk guidance).

Retaliation penalties. DLSE enforces reinstatement, back pay, and penalties when employers punish workers for reporting injuries (risk guidance).

Why this matters to you. Enforcement creates leverage to secure your benefits. Prosecutors and agencies can penalize bad actors, and courts can award penalty payments directly to injured workers in some circumstances (DA enforcement examples).

When to Call a Lawyer

Consider speaking with a workers’ compensation attorney if you see any of these red flags:

• Employer not reporting work injury after written notice.

• Pressure to accept cash or sign releases.

• “Independent contractor” claim after you’re hurt.

• No insurance or the employer disappears.

• Serious injury, surgery, permanent impairment, or complex evidence gaps.

• Retaliation after reporting.

What attorneys do. Preserve evidence; prepare and file DWC forms and petitions; pursue urgent medical authorizations; present your case at WCAB; coordinate with DLSE/EDD; calculate long‑term benefits; pursue civil claims against a no workers comp insurance employer; and negotiate fair settlements (case‑building and benefits; misclassification strategy).

Fees. In California workers’ comp, fees are typically contingency‑based (often about 10–15%) and approved by the judge, with no upfront payment required. This makes help accessible when you’re out of work (Bosco Legal guide).

To understand the hearing process and medical disputes, explore our explainer on QMEs and the IMR process.

Protecting Vulnerable & Undocumented Workers

Key assurance. “Immigration status does not affect entitlement to workers’ compensation benefits; claims are kept confidential from immigration enforcement.” (Bosco Legal guide)

Confidential reporting tips. Speak first with trusted legal aid or a worker center. Ask for interpreter services. Send written injury notice to your employer, but coordinate with counsel if you fear retaliation.

Community resources. Legal Aid, California Rural Legal Assistance, and local worker centers can help navigate claims and retaliation risks. Many offer multi‑language support.

Language access. The DWC provides forms in Spanish and other languages. Interpreters are available at medical visits and hearings at no cost.

For more guidance tailored to immigration concerns, read our overview of workers’ comp for undocumented workers.

Critical Deadlines

Deadlines are strict — missing them can bar your claim, especially when employer workers comp fraud California tactics involve delay.

• Notify your employer ASAP. Best practice is written notice within days (generally within 30 days under California guidance). Don’t wait.

• File the DWC‑1 promptly. Aim to file immediately; in any case, within one year of the injury or discovery for delayed injuries. If the employer won’t provide it, download the DWC‑1 form and file yourself.

• Report suspected fraud immediately. Delays benefit employers who hide claims.

Time‑sensitive checklist.

• Notify employer today.

• See a doctor today and state it’s work‑related.

• Request DWC‑1 within one working day; if ignored, file it yourself.

• Preserve evidence and witness contacts now.

• If resistance continues, speak with a lawyer within two weeks.

FAQ

Can an employer fire me for reporting an injury?

No. Retaliation is illegal. You can file a complaint with the Labor Commissioner (DLSE) for reinstatement and back pay, and pursue penalties against the employer (anti‑retaliation enforcement). If your employer is not reporting work injury or punishing you for speaking up, document everything and report it immediately.

Do undocumented workers get workers’ comp in California?

Yes. Immigration status does not affect entitlement to workers’ compensation benefits, and claims are kept confidential from immigration enforcement (Bosco Legal guide). If you suffered an under the table work injury, you can still file a claim and request interpreters as needed.

What if my employer says I’m an independent contractor?

Use the ABC test: an employer must prove (A) free from control, (B) outside usual course of business, and (C) customarily engaged in an independent trade (classification guide). For misclassified workers and injury claims, file your DWC‑1 and a DLSE complaint to correct status and protect benefits.

Who pays if my employer has no insurance?

You can seek benefits from the Uninsured Employers Benefits Trust Fund and may sue the employer directly — the employer faces criminal and civil penalties for operating uninsured (UEBTF and enforcement; DA fraud enforcement). A no workers comp insurance employer should be reported immediately.

How do I report employer workers comp fraud California?

File your claim with the DWC‑1, then report misclassification/wage issues to DLSE, payroll fraud to EDD, and insurance fraud to the Department of Insurance. For criminal activity, contact your local DA’s fraud unit — see state guidance on workers’ comp fraud prevention and reporting.
