What Is the Deadline to Report a Workplace Injury in Missouri?

30 Days—Injured workers must report their injuries to their employer within 30 days of the accident or the discovery of an occupational illness (RSMo § 287.420).

How to Properly Report a Work Injury:

  • Provide written notice (email, letter, or official work injury form).
  • Include:
    • Date, time, and location of the accident.
    • Details of the injury and symptoms.
    • Names of witnesses, if applicable.

Failure to report the injury within 30 days could result in claim denial unless there’s a valid reason for the delay (e.g., unconsciousness, hospitalization).

🔹 Pro Tip: Always keep a copy of your injury report for your records. If your employer refuses to accept the report, send it via email or certified mail to create a paper trail.

How Long Do You Have to File a Workers’ Compensation Claim in Missouri?

2 YearsMissouri law requires injured workers to file a workers’ compensation claim within two years of the date of injury or last payment of benefits (RSMo § 287.430).

🔹 Exception: If your employer fails to report the injury to the Missouri Division of Workers’ Compensation, the deadline extends to three years.

What If I Miss the Filing Deadline?

If you fail to file within the two-year limit, your workers’ compensation benefits may be permanently lost.

When Does the Workers’ Comp Filing Deadline Start?

The two-year deadline typically begins on:

  • The date of injury – For accidents like falls, burns, or fractures.
  • The date of the last benefit payment – If you received medical or wage replacement benefits, the clock restarts on the last payment date.
  • The date of diagnosis – If the injury is occupational (e.g., repetitive stress injury, toxic exposure), the clock starts when the worker becomes aware of the condition.

📌 Example: If a construction worker develops lung disease due to asbestos exposure, the deadline starts when a doctor confirms the illness is job-related.
