Missouri Workers’ Comp Deadlines Explained: Reporting vs. Filing

Published:

If you were hurt on the job, understanding the difference between reporting your injury and filing a workers’ compensation claim is critical – we can help!

Many injured workers assume that simply telling their employer is enough, only to find out later that additional steps were required to fully protect their rights.

If you’re unsure whether your injury was properly reported or whether you’ve met Missouri’s filing deadlines, it’s important to get clear answers before it’s too late.

Why Deadlines Matter in Missouri Workers’ Compensation

Missouri workers’ compensation claims follow strict timelines. Two of the most important—and most commonly confused—are:

  • The deadline to report your injury to your employer
  • The deadline to formally file a claim

These are not the same thing. Many valid claims run into trouble simply because one of these steps wasn’t completed on time or properly documented.


Deadline #1: Reporting Your Injury to Your Employer

In Missouri, you generally must:

Report your workplace injury within 30 days

What Counts as “Reporting”?

You should notify your employer (or supervisor) that:

  • You were injured
  • The injury happened at work
  • When and how it occurred

Best practice: Report the injury in writing and keep a copy. Even if you tell a supervisor verbally, follow up with an email or written report.

What Happens If You Don’t Report Within 30 Days?

Failing to report your injury within 30 days could:

  • Give the insurance company a reason to deny your claim
  • Create disputes about whether the injury is work-related

There are limited exceptions, but relying on them is risky.

Deadline #2: Filing a Workers’ Compensation Claim

Reporting your injury is not the same as filing a claim.

To protect your rights, you must formally file a claim with the Missouri Division of Workers’ Compensation.

Missouri Filing Deadlines

  • 2 years from the date of injury
  • 3 years if your employer failed to file a Report of Injury with the state

Why Filing Matters

Even if:

  • Your employer is paying medical bills
  • You’re receiving some benefits

You still may need to file a formal claim to:

  • Preserve your right to future benefits
  • Protect against benefits being suddenly cut off
  • Address disputes about treatment, wages, or disability

Common Mistakes That Can Hurt Your Claim

1. Waiting Too Long to Report

Some workers delay reporting because:

  • Pain seemed minor at first
  • They didn’t want to cause trouble at work

Unfortunately, delays often lead to disputes.

2. Assuming the Employer “Took Care of It”

Employers may say they’ve “filed everything,” but that doesn’t always mean your legal claim is protected.

3. Not Filing Because Benefits Started

Even if benefits begin, issues can arise later—especially around:

  • Medical treatment approval
  • Work restrictions
  • Settlement or disability ratings
