If you were hurt on the job, you probably want to know two things. How does workers comp work in California, and when will the money start? Workers’ compensation is generally a no-fault system. It pays for medical care and part of your lost wages after a work injury or illness. Below, we explain who is covered, each step of a claim, and when payments are due.
How does workers comp work in California?
You report the injury to your employer, and your employer must give you a claim form “within one working day.” Once you file it, the employer must authorize medical treatment within one working day, up to $10,000 while the claim is reviewed (Labor Code § 5402). If you miss work, the first temporary disability payment is generally due within 14 days.

How Does Workers Comp Work in California?
Under California workers’ compensation law, the system provides benefits to employees who are injured or become ill because of their work. Benefits may include medical treatment, partial wage replacement, permanent disability payments, and help returning to work. It is generally a no-fault system, so you typically do not have to prove your employer was negligent.
In exchange, workers’ compensation is usually “the sole and exclusive remedy” against the employer for a covered injury (Labor Code § 3602). Exceptions exist, such as a willful physical assault by the employer, and some injuries also involve claims against third parties.
Who Is Covered?
Most California employees are covered, including many part-time and temporary workers. Coverage generally does not depend on how long you have worked for the employer. Immigration status does not remove these rights. State-law protections “are available to all individuals regardless of immigration status,” except reinstatement barred by federal law (Labor Code § 1171.5).

How to File for Workers’ Comp in California: Step by Step
Every claim is different, but the process generally follows these steps.
1. Report the injury to your employer
Tell your employer about the injury as soon as possible. Consider doing it in writing so there is a record. The law generally requires written notice “within thirty days after the occurrence of the injury” (Labor Code § 5400). Reporting is protected: Labor Code section 132a bars employers from punishing workers for filing a claim. Learn more about being fired for filing workers’ comp in California.
2. Get medical treatment
Get emergency care right away if you need it, and tell the provider the injury is work-related. Many employers use a Medical Provider Network (MPN) for ongoing care. Whether you can see your own doctor depends mainly on whether you predesignated one before the injury (see the FAQ below).
3. Complete and return the DWC-1 claim form
Your employer must give you a claim form in person or by mail “within one working day of receiving notice or knowledge of injury” (Labor Code § 5401). Complete the employee section, sign it, return it, and keep a copy. The form counts as filed when it is personally delivered to the employer or received by mail.
4. The claims administrator reviews the claim
The employer sends the claim to its claims administrator. According to the DWC-1 form, the administrator “must notify you within 14 days whether your claim is accepted or whether additional investigation is needed” (DWC-1).
5. Benefits, settlement, or a dispute
If the claim is accepted, you receive the benefits that apply to your injury. The case may later resolve through a settlement. Our articles explain when workers’ comp may offer a settlement and what a settlement chart shows about case value. If the administrator denies it, you may have the right to challenge the decision before the Workers’ Compensation Appeals Board (WCAB).
When Does Workers’ Comp Start Paying in California?
Medical treatment can start within one working day of filing the claim form. The first wage payment is generally due within 14 days. The timeline below shows what the law requires and when.
| When | What must happen | Source |
|---|---|---|
| Within 30 days of the injury | You give your employer written notice of the injury | Lab. Code § 5400 |
| 1 working day after the employer learns of it | The employer gives you a claim form | Lab. Code § 5401 |
| 1 working day after you file the form | The employer authorizes medical treatment, up to $10,000 until the claim is accepted or rejected | Lab. Code § 5402(c) |
| 14 days | The administrator tells you whether the claim is accepted or needs more investigation | DWC-1 |
| 14 days after knowledge of the injury | First temporary disability payment, unless liability is denied first | Lab. Code § 4650(a) |
| Every two weeks | Temporary disability payments generally continue while you cannot work | CDI guide |
| 90 days after filing | If not rejected, the injury is presumed compensable | Lab. Code § 5402(b) |
How much each payment is depends on your earnings and the rates for your date of injury. See how much workers’ comp pays in California and whether workers’ comp is taxable.
What Benefits Can You Receive?
California workers’ compensation provides several types of benefits depending on your injury, your ability to work, and whether you fully recover.
| Benefit | What it covers |
|---|---|
| Medical treatment | Doctor visits, surgery, medication, therapy for the work injury or illness |
| Temporary disability | Partial wage replacement if your injury prevents you from doing your usual job while you recover |
| Permanent disability | Payments if your work-related injury or illness results in lasting disability |
| Supplemental job displacement | A voucher “redeemable for up to $6,000” for retraining, for injuries on or after January 1, 2013, if you meet the eligibility requirements (CDI) |
| Return-to-Work Supplement | A one-time payment of $5,000 may be available to eligible workers who received the voucher (CDI) |
| Death benefits | Payments to eligible dependents when an employee dies as a result of a work-related injury or illness |
Serious injuries, such as a traumatic brain injury at work, can involve several of these benefits at once. Some injured workers also ask about workers’ comp and state disability at the same time.
How Long Do I Have to File a Workers’ Comp Claim?
Different deadlines apply at different stages. Written notice to the employer is generally due within 30 days of the injury (Labor Code § 5400). Proceedings to collect benefits generally must begin within “one year.” That year can run from the date of injury, the end of paid benefits, or the last date certain benefits were provided (Labor Code § 5405). Injuries that develop over time follow special rules for the date of injury.
If you think a deadline has passed, do not assume your rights are gone. An attorney can evaluate which deadlines apply to your situation.
What If Your Claim Is Denied?
A denied claim does not necessarily end your case. Claims administrators often dispute whether the injury is work-related, when you reported it, or the medical evidence. The Workers’ Compensation Appeals Board (WCAB) can resolve these disputes. Disagreements over requested treatment go through utilization review and then independent medical review (IMR). Disputes over your disability rating may involve a Qualified Medical Evaluator (QME), or an Agreed Medical Evaluator (AME) when you have an attorney (CDI guide). Abramson Labor Group represents injured California workers through the entire workers’ comp process, including denied and delayed claims.
Frequently Asked Questions About How Workers’ Comp Works in California
Can I see my own doctor?
Possibly. The DWC-1 form explains that if you “previously designated your personal physician or a medical group” before the injury, you may be able to treat with them (DWC-1). Otherwise, your employer’s Medical Provider Network usually controls who treats you, at least at first.
Am I paid for the first few days I miss work?
Not always. The law generally does not pay for “the first three days” of disability. The exceptions: the disability lasts more than 14 days, or you are admitted to a hospital as an inpatient (Labor Code § 4652). In those cases, payment covers the disability from the start.
Can I get partial workers’ comp if I go back to light duty?
Possibly. If you can work but earn less while you recover, temporary partial disability pays “two-thirds of the weekly loss in wages” (Labor Code § 4654). The weekly loss is the difference between your average weekly earnings and what you can earn during the disability (Labor Code § 4657). Unemployment benefits received during that time reduce the payment.
What happens if my workers’ comp payment is late?
Generally, “the amount of the late payment shall be increased 10 percent and shall be paid, without application, to the employee” (Labor Code § 4650(d)). You do not have to ask for it. Some exceptions apply, such as payments due within 14 days after the claim form is filed.
Can I get workers’ comp for stress or a mental health injury?
Possibly, but the rules are stricter. The “actual events of employment” generally must be “predominant as to all causes combined.” You also generally must have worked for that employer “for at least six months.” That rule does not apply to an injury “caused by a sudden and extraordinary employment condition” (Labor Code § 3208.3).
What if my employer does not have workers’ comp insurance?
You may still have options. California employers must carry coverage, and an uninsured employer is responsible for the bills related to the injury. An injured worker can file a claim with the Uninsured Employers Benefits Trust Fund (UEBTF) and may also file a civil lawsuit in addition to the workers’ compensation claim (California Department of Insurance).
What if my employer calls me an independent contractor?
The label does not decide it. Under California’s ABC test, a worker is generally “considered an employee rather than an independent contractor.” The hiring entity must prove three conditions, including that the work is “outside the usual course of the hiring entity’s business” (Labor Code § 2775). See what to do if you are misclassified.
Can my employer fire me for filing a workers’ comp claim?
No. The state’s claim form says “it is illegal for your employer to punish or fire you for having a job injury or illness” (DWC-1). A Labor Code 132a petition generally has a one-year deadline. The California Supreme Court also held in City of Moorpark v. Superior Court (1998) that “section 132a does not provide an exclusive remedy.”
What if my injury developed over time?
For injuries that build over time, the date of injury is when you “first suffered disability therefrom.” You also must have known, or reasonably should have known, it “was caused by his present or prior employment” (Labor Code § 5412). That date can affect which deadlines apply.
