Washington State Workers' Compensation: Certifying Out‑of‑State Claims

What Makes Washington's Out‑of‑State Certification Unique

Washington's workers' compensation system is governed by the State Compensation Board (SCB), which requires that any claim involving an injury sustained while performing work outside the state be certified before benefits can be paid. Unlike many states that allow direct claim filing by out‑of‑state insurers, Washington mandates a formal certification to confirm that the injury is work‑related and that the claimant is covered under Washington law.

Eligibility Criteria for Out‑of‑State Workers

To qualify for Washington benefits, a claimant must meet all of the following:

• Work performed for a Washington employer or a company that has a Washington payroll tax license.
• Injury or illness that occurred while traveling for work, on a business trip, or performing duties that are part of the employer's business activities.
• Claim filed within 90 days of the injury date.

Employees who work remotely or travel for non‑business reasons are typically excluded, unless the injury occurs during a legitimate work assignment.

Certification Process Steps

Step 1: Employer Notification

The employer must submit a written notice to the SCB within 15 days of the injury. The notice includes the employee's name, injury date, location, and a brief description of the incident.

Step 2: SCB Review

The SCB evaluates the notice for completeness and verifies that the employer holds a valid Washington payroll tax license. If information is missing, the board issues a Request for Information (RFI).

Step 3: Claim Submission

Once the SCB grants certification, the claimant files a formal claim with the board or the employer's insurance carrier. The claim must include medical records, a statement of the injury, and any relevant employment documentation.

Step 4: Benefit Determination

After review, the SCB determines benefit eligibility, calculates wage replacement, and authorizes medical treatment under the board's guidelines.

Key Deadlines and Timelines

Common Pitfalls and How to Avoid Them

• Missing Employer License – Verify the employer's payroll tax license before filing.
• Late Filing – Use the 90‑day window wisely; late claims are usually denied.
• Inadequate Documentation – Provide detailed medical reports and job descriptions to support the work‑related nature of the injury.

Impact on Employers and Employees

Employers must maintain accurate payroll records and ensure their out‑of‑state employees are covered under Washington's workers' compensation laws. Employees benefit from a clear pathway to receive wage replacement and medical care, but must act promptly to meet certification and filing deadlines.

Conclusion

Washington's out‑of‑state workers' compensation certification process protects both employers and injured employees by ensuring that only legitimate work‑related injuries receive benefits. Understanding the eligibility rules, certification steps, and deadlines is essential for compliance and timely access to support.
