Most people assume they have plenty of time to file a workers’ compensation claim and deal with the paperwork after getting hurt on the job. See a medical provider, focus on healing, and sort out the claim later.
In Montana, that instinct can bar your workers’ compensation claim because the clock to report your injury starts ticking the moment the injury occurs—not when you get around to telling someone about it.
Here’s what the law actually requires and why the deadline that applies to on-the-job injuries is shorter than you might think.
The 30-Day Rule Under Montana Law
Under Montana Code Annotated § 39-71-603, an injured worker must notify their employer or their employer’s workers’ compensation insurer of a workplace injury within 30 days of the accident.
The notice must include:
- The time of the accident
- The place of the accident
- The nature of the injury
This is not a soft deadline. The statute states that a claim “may not be considered compensable” unless notice is provided within that 30-day window.
An employer’s actual knowledge of the accident can satisfy the notice requirement. However, the injured worker is ultimately responsible for ensuring the employer or its insurer receives notice within 30 days of the accident.
This means a worker who is hurt on the job but assumes the injury isn’t serious enough to report may face significant problems if they wait beyond the 30-day deadline.
A Second, Separate Deadline: Filing the Actual Claim
Reporting your injury to your employer is only the first step.
The second step is filing the actual workers’ compensation claim, and many injured workers don’t realize there is a separate deadline.
Under Montana Code Annotated § 39-71-601, an injured worker has 12 months (one year) from the date of the accident to file a written claim with:
- Their employer
- The employer’s workers’ compensation insurer
- The Montana Department of Labor and Industry
That deadline may be extended to 24 months in limited circumstances, such as:
- A latent injury that was not immediately apparent
- A lack of knowledge that a disability was connected to the workplace accident
However, this extension is not automatic, and it’s always best to file a signed First Report of Injury as soon as possible after a work-related injury occurs.
If you need assistance filing a claim, visit the Montana Department of Labor and Industry.
Two Deadlines You Need to Remember
After a workplace injury in Montana, two separate clocks begin running:
- 30 days to notify your employer or the employer’s workers’ compensation insurer of the injury.
- 12 months to file the formal workers’ compensation claim with your employer, the insurer, or the Montana Department of Labor and Industry.
Important: Don’t hesitate to ask your employer for the name and contact information of its workers’ compensation insurer. Montana law requires employers to conspicuously post this information at the workplace, and you also have the right to request it so you can file a claim directly with the insurer.
What This Means for Injured Workers in Missoula and Hamilton
If you’ve been injured on the job in western Montana, here are a few practical tips:
- Report your injury immediately, even if it seems minor. Some injuries become much more serious over time, and waiting can jeopardize your claim.
- Keep detailed records, including:
- A copy of the written notice you provided
- The date you submitted it
- The name of the person who received it
- Seek medical attention as soon as possible. Be sure to tell your healthcare provider about your job duties and any physical limitations caused by your injury.
- Remember that reporting an injury and filing a claim are two different legal requirements. Completing one does not satisfy the other.
Missing the filing deadline because you assumed reporting the injury was enough is a common—and avoidable—mistake.
When to Talk to an Attorney
Workers’ compensation deadlines in Montana are strict, and insurers routinely examine the timing of a claim when looking for reasons to deny benefits.
If you’ve been injured at work and aren’t sure whether you’re still within the reporting or filing deadlines—or if your claim has already been delayed or denied because of a timing issue—it’s worth getting clear legal guidance before assuming it’s too late.
