Montana Workers' Compensation Calculator

Montana's workers' compensation benefits are available regardless of who caused the workplace injury. The state's negligence rules become relevant only if you pursue a separate third-party claim — for example, suing a equipment manufacturer or a negligent contractor alongside your workers' comp claim.

How Montana Law Affects Your Workers' Compensation Case

The statute of limitations for this type of claim in Montana is 1 year — shorter than the national average of 1.9 years. This compressed timeline means you need to consult an attorney and begin gathering evidence quickly.

Temporary disability benefits in Montana replace 67% of your pre-injury wages, subject to a weekly cap of $911. There is also a minimum benefit of $228 per week. Benefits begin after a 4-day waiting period. If your disability extends beyond 21 days, the waiting period is paid retroactively.

Permanent impairment in Montana is evaluated using the AMA Guides, 6th Edition. The edition or rating system used matters significantly because different versions can produce substantially different impairment ratings for the same injury, directly affecting your permanent disability benefits.

Montana allows injured workers to choose their own treating physician for workers' compensation claims. In states without this right, the employer or insurer selects the doctor, which can affect both the quality of care and the impairment rating you receive.

Montana requires injured workers to notify their employer within 30 days of the workplace injury. This notification should be in writing and include the date, time, location, and nature of the injury. The formal workers’ compensation claim filing is a separate process with its own deadline, but missing the employer notification requirement can jeopardize your entire claim.

Montana provides vocational rehabilitation benefits for injured workers who are unable to return to their previous job. These benefits may include job retraining, education assistance, resume preparation, job placement services, and maintenance allowances during the retraining period. If your workplace injury has permanently limited your ability to perform your previous occupation, vocational rehabilitation can help you transition to suitable alternative employment.
