One of the cruelest outcomes in workers' compensation is a valid injury claim that gets thrown out not because the injury did not happen — but because the worker waited too long to file. New York has strict deadlines for workers' comp claims, and missing them is almost always fatal to your case. This guide explains the rules, how they differ for different types of injuries, and why filing sooner is almost always the right call.
If you are unsure whether your deadline has passed, stop reading and contact an attorney immediately. There is no benefit to waiting — a free consultation costs you nothing, and finding out your rights are still intact could be worth a great deal.
The Key Deadlines at a Glance
The Two-Year Statute of Limitations: WCL §28
The primary statute of limitations for New York workers' comp claims is found in WCL §28. For most traumatic injuries — a single accident with an identifiable date — the rule is straightforward: you must file your claim (the C-3 Employee Claim form) with the Workers' Compensation Board within two years of the date of accident.
This deadline applies regardless of whether the insurance carrier is already paying you benefits. Even if you have been receiving weekly payments without filing a formal C-3, you must still file to preserve all of your rights. Carriers sometimes pay informally without a formal claim being on file, and workers are sometimes unaware that the two-year clock is ticking.
Filing the C-3 protects your rights. Even if you are unsure about pursuing benefits, filing the C-3 locks in your date of injury for the record. You can always decide later not to pursue benefits; you cannot undo a missed deadline.
The 30-Day Employer Notice Requirement
Separate from the two-year filing deadline, WCL §18 requires that you provide written or oral notice to your employer within 30 days of the accident. This is distinct from filing the C-3 with the Board. You must do both.
The consequences of missing the 30-day notice window are serious — the employer can raise a "lack of notice" defense that could limit your benefits. However, the Board has discretion to excuse a late notice if:
- The employer had actual knowledge of the accident (e.g., a supervisor witnessed it)
- The employer was not prejudiced by the late notice
Even if you think you may have missed the 30-day window, do not assume your claim is lost — contact an attorney and let them evaluate whether an excuse applies.
Occupational Disease: Different Rules
For occupational diseases — conditions that develop from the nature of the work over time rather than a single accident — the statute of limitations works differently. Under WCL §28:
The two-year period begins from the later of:
- The date you became disabled from the disease, OR
- The date you knew or should have known that the disease was work-related
Examples of occupational diseases include occupational hearing loss, asbestos-related conditions (mesothelioma, asbestosis), silicosis, repetitive stress injuries, and chemical exposure illnesses.
The "knew or should have known" standard is important — it means the clock may start before you receive a formal diagnosis. If a doctor tells you that your condition is consistent with your occupational exposures, that may start the clock even if a specific occupational disease is not yet confirmed.
Gradual Onset and Repetitive Stress Injuries
Repetitive stress injuries (carpal tunnel syndrome, tendinitis, rotator cuff degeneration, etc.) and other gradually-developing conditions occupy a middle ground between single-accident injuries and occupational diseases. For these injuries, the "date of accident" is typically the date of last injurious exposure or the date you first became disabled.
Courts and the Board look at when you first experienced disability attributable to the work activity. If you have been developing symptoms for years but continued to work, the clock may start from the day you stopped being able to perform your regular job duties due to the condition.
Death Claims
If a worker dies from a work-related injury or occupational disease, dependents may file a claim for death benefits. The two-year limitation period for death claims runs from the date of death, not the date of injury. If the worker had a pre-existing open comp case, the death benefits claim is filed as part of that case.
What Happens If You Miss the Deadline?
If the statute of limitations has expired, the carrier or employer can raise it as a defense. The Board has very limited authority to excuse a missed filing deadline — far less discretion than courts typically have with statutes of limitations in other areas of law. In most cases, a missed two-year deadline means the claim is permanently barred.
There is no automatic tolling (pausing of the clock) for physical or mental incapacity, minority, or ignorance of the law, in most circumstances. This is why prompt action matters so much.
Why You Should File Early
Even if you are still being treated and do not yet know the full extent of your injuries, filing the C-3 early has no downside and significant upside:
- It locks in your date of injury before the deadline can become an issue
- It puts the carrier on formal notice, which can speed up treatment authorizations
- It establishes your case in the Board's system so hearings can be scheduled
- It protects your right to benefits even if your condition worsens significantly later

If You Think You Have Already Missed the Deadline
Before concluding that your rights have expired, consult an attorney. The question of when the statute of limitations began to run — especially in occupational disease and gradual onset cases — is often a fact-intensive legal question. A date that appears to be beyond the two-year window based on a superficial analysis may still be within the limitations period under the correct legal standard. Do not self-diagnose a missed deadline — let an attorney make that determination. To understand your options and next steps, read our guide on your rights as an injured worker in New York.
