Workers Comp Statute of Limitations
The single fastest way to lose a workers comp claim is to miss a deadline. The deadlines are short, state-specific, and unforgiving. A worker who waits a year to report an injury, or two years to file a formal claim, usually finds the case dismissed before any merits hearing. This page is the national overview of the deadlines that govern when a worker has to act.
The exact dates vary by state. The per-state pages on this site list each state’s specific statute and the most recent published deadline. The framework below explains what each deadline does.
The two clocks every state runs
Every state workers comp statute runs at least two clocks:
Notice to employer. The worker has to inform the employer that an injury occurred. The notice deadline is short, typically 30 days, and it starts on the day of the injury (or in occupational disease cases, the day the worker knew or should have known the condition was work-related).
Formal claim filing. The worker has to file a claim form with the state workers comp commission, board, or industrial commission. The filing deadline is longer, typically one to three years, and starts on the date of injury or the date of last payment of compensation.
These two clocks run independently. Hitting the notice deadline does not satisfy the formal filing deadline. Filing the formal claim does not waive a defective notice. Both deadlines have to be met.
Notice deadlines by state, common windows
Notice deadlines vary, but most states cluster around a few standard windows:
| Window | Sample states |
|---|---|
| 30 days | Florida, Georgia, Texas, North Carolina, New York |
| 14 days | Tennessee (for traumatic injury, with extensions) |
| 60 days | Illinois (45 days for most injuries) |
| 90 days | Massachusetts (within 4 days for traumatic injury and 90 days for occupational disease) |
| As soon as practicable | Several states use this standard without a fixed day count |
A “30-day notice” deadline is not 30 business days. It is 30 calendar days, including weekends and holidays. Miss day 30 and the carrier has a clean defense.
There are state-specific exceptions to a missed notice deadline:
- Actual knowledge. If the employer had actual knowledge of the injury (e.g., the supervisor witnessed it), the worker can sometimes excuse the failure to give formal notice.
- Lack of prejudice. Some states require the employer to show actual prejudice from the late notice to assert the defense.
- Mental incapacity. Some states toll the notice clock while the worker is mentally incapacitated.
- Minority. If the worker is a minor, the clock may be tolled until age of majority.
These exceptions are state-specific and narrow. Counting on them is risky.
Formal claim filing deadlines
The formal claim filing deadline is the statute of limitations. It is what most lawyers mean when they say “statute of limitations” in a workers comp context. The deadline varies sharply by state:
| Deadline | Sample states |
|---|---|
| 1 year | Florida (2 years from date of injury for petition for benefits, with last payment tolling) |
| 2 years | Florida (latest date by which a petition for benefits must be filed under most circumstances; the rule has complexity around last payment dates) |
| 2 years | California (DWC-1 must be filed within 1 year of injury or last benefit, but the statute has multiple deadlines depending on issue) |
| 1 year | Georgia (1 year from date of injury, or 1 year from last remedial treatment, or 2 years from last income benefit, whichever applies) |
| 3 years | New York (within 2 years of accident or 2 years of knowledge of occupational disease) |
The numbers in this table are illustrative; the actual statutes have multiple subsections, exceptions, and tolling rules. The per-state pages on this site list the controlling citation for each state.
How the clock starts
For a traumatic injury (a single incident), the clock typically starts on the date of the incident.
For an occupational disease (a condition that developed over time, like carpal tunnel from years of repetitive work, or asbestosis from years of exposure), the clock starts later. Most states use a discovery rule: the deadline runs from the date the worker knew or should have known that the condition existed and was related to work.
For a cumulative trauma injury, the rule varies. Some states use the date of the last exposure. Others use the date the worker first lost time from work. Others use the date the worker first sought medical treatment.
The discovery rule is litigated frequently. A worker diagnosed with mesothelioma in 2023 from asbestos exposure in 1985 typically has a deadline running from 2023, not 1985.
Tolling rules
The clock can be paused (tolled) in defined circumstances:
Last payment of compensation. Most states extend the formal claim filing deadline by a defined period after the carrier’s last payment of indemnity or medical. A worker receiving TTD payments has the clock tolled while the payments continue.
Continuing treatment. Some states toll the deadline while the worker is receiving authorized medical treatment, even without indemnity payments.
Active litigation. A claim that is in active litigation generally tolls the deadlines on related issues within the same claim.
Minority. A minor’s claim is often tolled until the worker reaches age 18.
Mental incapacity. A worker who is incapacitated and unable to file may have the deadline tolled.
Fraud or concealment by the employer. If the employer fraudulently concealed the injury or the worker’s right to file, the deadline may be tolled until the fraud is discovered.
Tolling is fact-specific. The carrier will argue tolling does not apply; the worker will argue it does.
Deadlines for specific events inside a claim
Beyond the main notice and filing deadlines, several other deadlines run inside a claim:
- Medical treatment. Many states require the worker to seek initial medical treatment within a defined window for the bills to be carrier-paid.
- Mileage reimbursement. Mileage to and from medical appointments has to be submitted within a window (often 90 days).
- Appeal of a denial. A denial decision usually has a 20 to 30 day appeal window.
- Request for review of a commission order. The appellate window is typically 30 days from the order.
- Reopening a closed claim. If new symptoms appear after a claim has closed, most states have a reopening statute with its own deadline (often 2 to 5 years from the original injury or settlement).
Each of these is a separate clock with its own consequences.
Federal claims have their own deadlines
Workers covered by federal statutes are not subject to state deadlines:
- FECA (federal employees). Three years from the date of injury, with discovery rule extensions for occupational disease. See the FECA guide.
- Longshore Act (maritime workers). One year from injury for traumatic injury claims, two years for occupational disease. See the Longshore Act overview.
- Federal Employers’ Liability Act (railroad workers). Three years from the date of injury.
- Jones Act (seamen). Three years under general maritime law.
A worker covered by both state and federal statutes has to meet whichever deadline is shorter or risk losing the claim under one of the two systems.
What to do if a deadline is approaching
If a deadline is close, three immediate steps:
- File the formal claim form now. Even if the file is incomplete, filing the claim form stops the clock. The substantive issues can be developed after filing.
- Document the notice. If notice was given verbally, send a follow-up email or letter to the employer the same day. Keep a copy.
- Call a workers comp attorney. Most attorneys do free consultations and many can file the protective claim form the same day.
A missed deadline is the hardest defense to overcome at hearing. A timely-filed claim with weak merits is fixable. A late claim is usually not.
Per-state deadlines
The exact deadlines for each state’s notice window, formal claim filing window, and reopening window are listed on each state page on this site. The per-state pages also cite the controlling statute for each deadline.
