California Workers Comp Statute of Limitations
Missing this deadline doesn't just slow your claim down — in most cases, it ends it. California law sets a hard cutoff for filing, and insurers know exactly how to use a missed date against you.
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 California'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
California, like most states, recognizes that not every injury announces itself immediately. Occupational diseases discovered well after the triggering exposure typically get a modified deadline tied to diagnosis rather than exposure date. Similar flexibility sometimes applies to minors or where an employer actively concealed a workplace injury. None of these exceptions are automatic — they require specific facts to invoke.
What Happens If You Miss It
Once California'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.
