Washington Workers Comp Statute of Limitations
Washington's filing deadline isn't a formality. Once it passes, the legal right to benefits for that injury is generally gone, regardless of how strong the underlying claim was.
Filing Deadline
1 year
From the date of injury. Some exceptions apply — see tolling rules below. Not legal advice.
Why This Deadline Exists
The reasoning behind Washington's deadline is straightforward: claims get harder to verify the longer they sit, and insurers use that to argue against late filings. The deadline forces the process to move while the facts are still clear.
When the Deadline Can Be Extended
A handful of situations can extend — or 'toll' — this deadline. Occupational diseases that develop gradually often get a discovery-rule exception, starting the clock when the condition is diagnosed rather than when the underlying exposure began. Claims involving minors, and cases where an employer concealed the injury or fraudulently discouraged a claim, may also toll the deadline. These exceptions are narrow and fact-specific — don't assume one applies without confirming it with Washington's workers comp agency or an attorney.
What Happens If You Miss It
Once Washington's deadline has passed, reopening the claim is rarely possible through the normal process. A small number of narrow exceptions exist (see tolling rules above), but for most missed deadlines, the right to benefits for that injury is gone.
