New Hampshire Workers Comp Statute of Limitations
Missing this deadline doesn't just slow your claim down — in most cases, it ends it. New Hampshire law sets a hard cutoff for filing, and insurers know exactly how to use a missed date against you.
Filing Deadline
2 years
From the date of injury. Some exceptions apply — see tolling rules below. Not legal advice.
Why This Deadline Exists
Filing deadlines exist to give employers and insurers a reasonable window to investigate a claim while evidence and memories are still fresh. New Hampshire balances that against giving injured workers enough time to understand the full extent of an injury before locking in a filing date.
When the Deadline Can Be Extended
New Hampshire, 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
A missed deadline in New Hampshire isn't usually something that can be fixed after the fact. The claim is typically closed to the insurer's benefit, which is exactly why acting early — even before you're certain you'll need to file — matters more than waiting for complete certainty about the injury's severity.
