How to Complete Washington State Workers' Compensation Claim Forms

Key Differences for Washington Workers' Compensation Claims

Washington requires the use of the WC‑1 form for initial injury reporting and the WC‑2 form for detailed claim filing. Unlike many states, the WC‑1 must be submitted within three days of the injury, and the WC‑2 must be filed within 30 days of the employer's acknowledgment. Both forms are available online through the Washington State Department of Labor & Industries (L&I) and must be signed by the employee, employer, and a medical provider when applicable.

When to Use Each Form

The WC‑1, also called the "First Report of Injury," is the employee's quick notice to the employer. It captures basic facts: date, time, location of the incident, and a brief description of the injury. The WC‑2, "Claim for Workers' Compensation Benefits," is the formal request for wage replacement, medical benefits, and other compensations. Use WC‑2 only after the employer has acknowledged the WC‑1 and provided a claim number.

Step‑by‑Step Completion Guide

1. Gather Required Information

• Employee's full name, address, and Social Security number
• Employer's legal name, address, and L&I account number
• Exact date and time of the incident
• Detailed description of how the injury occurred
• Names of any witnesses
• Medical provider's name, address, and diagnosis (for WC‑2)

2. Fill Out the WC‑1 Form

Enter the basic incident details in Section A, then sign and date the form. The employee must give the completed WC‑1 to the employer no later than the third calendar day after the injury.

3. Employer's Role

The employer reviews the WC‑1, adds their information in Section B, and forwards the form to L&I within three days. They also issue a claim number, which the employee will use on the WC‑2.

4. Complete the WC‑2 Form

Using the claim number, the employee fills out Section C with personal and employment details, then describes the injury in depth in Section D. A medical provider must complete the medical certification in Section E, confirming the diagnosis and treatment plan.

5. Submit the WC‑2 Form

Mail or e‑file the WC‑2 to L&I within 30 days of receiving the claim number. Keep copies of all documents for personal records.

Common Pitfalls and How to Avoid Them

• Missing the 3‑day deadline: Late WC‑1 submissions can delay claim processing and may affect benefit eligibility.
• Incomplete medical certification: Ensure the provider signs and dates every required field; omissions often result in a request for resubmission.
• Incorrect claim number: Double‑check the number on the WC‑2; a mismatch forces the claim back to the employer for correction.

Where to Find and Submit Forms

All Washington workers' compensation forms are downloadable from the L&I website (https://www.lni.wa.gov). The portal also offers electronic filing, which speeds up acknowledgment and reduces paper handling. For mailed submissions, use the address listed on the form instructions, typically the L&I Claims Processing Center in Olympia.
