Quick answer
Washington State calls its workers' compensation system 'industrial insurance,' and it is run by the Washington State Department of Labor and Industries. If you are hurt at work or develop an illness because of your job, you are generally entitled to medical care and partial wage replacement — you do not have to prove your employer did anything wrong. Report your injury to your employer right away and file a claim as soon as possible, because the deadline to file is as short as one year from the date of injury.

Washington-specific deadlines for workers compensation cases
Enter the date your problem happened to see which deadlines may already have passed. Not every deadline applies to every situation — this is a general estimate, not legal advice. Deadlines can be shorter, paused, or extended.
- Deadline to file a claim for a work injury: 1 year
No application is valid or enforceable unless filed within one year after the date of injury. Missing this deadline permanently bars the claim.
RCW 51.28.050
- Deadline to file a claim for an occupational disease: 2 years
The clock starts when a physician or licensed advanced registered nurse practitioner gives you written notice of the disease and advises that you may file a claim. A separate two-year period runs from the date of death if the worker dies of the occupational disease.
RCW 51.28.055
- Deadline to appeal a Department of Labor and Industries order to the Board of Industrial Insurance Appeals: 60 days
If you do not file a timely protest or notice of appeal, the order becomes final and binding on all parties. The 60-day period begins the day after the order is communicated to you or your representative.
RCW 51.52.060
- Deadline to appeal a Board of Industrial Insurance Appeals decision to superior court: 30 days
If this deadline is missed, the Board's decision becomes final. The appeal is perfected by filing a notice with the clerk of the superior court and serving copies on the Director and the Board by mail or in person.
RCW 51.52.110
- Deadline to file a retaliation complaint with the Department of Labor and Industries: 90 days
If your employer discharged or discriminated against you for filing or intending to file a workers' compensation claim, you must file a complaint with the Department of Labor and Industries within 90 days of the alleged violation.
RCW 51.48.025
These deadlines are general estimates. They can be shorter than they appear, and can be paused (“tolled”) or extended in specific situations. This is not legal advice. If any deadline is near or has passed, talk to a lawyer right away.

How to take action in Washington
- 1
Get medical treatment right away
See a doctor or go to an emergency room for your work injury or illness and tell your provider it is work-related so a Report of Accident can be submitted to the Department of Labor and Industries.
- 2
Report the injury to your employer
Notify your supervisor as soon as possible. If your employer is self-insured, you will file your claim directly with them on a Self-Insured Accident Report form.
- 3
File a claim with the Department of Labor and Industries
For most employers, your treating doctor files the Report of Accident with the Department of Labor and Industries, which opens your claim. You can also file online at lni.wa.gov or call 1-800-547-8367.
- 4
Cooperate with the claim investigation
Respond promptly to requests from the Department of Labor and Industries, attend any required medical examinations, and keep records of medical bills and missed workdays.

Protest or appeal a decision you disagree with
If you receive an order from the Department of Labor and Industries that you believe is wrong, you have 60 days from the date the order is communicated to you to file a protest or appeal under RCW 51.52.060.

Consider consulting a workers' compensation attorney
If your claim is denied, closed, or involves a permanent disability, an attorney who handles workers' compensation cases can help you navigate the appeals process. Many accept these cases on a contingency-fee basis, meaning no fee unless you recover benefits.

Common questions about workers compensation in Washington
How long do I have to file a workers' compensation claim in Washington?
For a work accident, you have one year from the date of injury to file a valid claim under RCW 51.28.050. For an occupational disease, you have two years from the date a physician or licensed advanced registered nurse practitioner gives you written notice of the diagnosis under RCW 51.28.055. Missing either deadline will bar your claim entirely.
What benefits does Washington workers' compensation pay?
Washington's industrial insurance system covers all reasonable and necessary medical treatment for your work-related condition. It also pays time-loss compensation — wage replacement equal to 60 to 75 percent of your gross wages, depending on how many dependents you have — for days you cannot work. If you have a lasting physical impairment, you may also receive a permanent partial disability award.
Does workers' compensation cover illnesses that develop over time, not just sudden accidents?
Yes. Washington's industrial insurance covers occupational diseases — conditions that develop from workplace exposures or activities over time, such as hearing loss from noise, lung disease from chemical exposure, or repetitive-motion injuries. The filing deadline differs from a sudden injury: you have two years from the date a physician notifies you in writing of the diagnosis.
Can my employer fire me for filing a workers' compensation claim?
No. Under RCW 51.48.025, it is illegal for an employer to discharge or in any way discriminate against a worker because the worker filed or communicated an intent to file a workers' compensation claim. If you believe you experienced retaliation, you can file a complaint with the Department of Labor and Industries within 90 days of the alleged violation.
What happens if my workers' compensation claim is denied?
If the Department of Labor and Industries issues an order denying or closing your claim, you have 60 days from when the order is communicated to you to file a protest or notice of appeal under RCW 51.52.060. Appeals go to the Board of Industrial Insurance Appeals. If the Board rules against you, you have 30 more days under RCW 51.52.110 to appeal to superior court.
My employer is self-insured. Does the process change?
Some large Washington employers are self-insured, meaning they pay workers' compensation claims directly rather than through the state fund. You report the injury to your employer and file your claim with them on a Self-Insured Accident Report form. The same RCW Title 51 rules, benefits, deadlines, and appeal rights apply, and you still have the right to appeal decisions to the Board of Industrial Insurance Appeals.
Are undocumented workers covered by Washington workers' compensation?
Yes. Washington's industrial insurance system covers workers regardless of immigration status. The law does not require legal work authorization to receive benefits or file a claim.
