- The employer submits the first report of injury or occupational disease form to its insurer within six days of notice of the accident, injury or disease; an employer without workers' compensation coverage submits it to the Department, and an employee may also submit one to the DepartmentARM 24.29.801 (amended eff. 2025-07-01)
- An employer or insurer that refuses or neglects to submit the reports needed to file and review a claim is assessed a penalty of 200 to 500 dollars for each offense, which it may contest in a Department hearingMCA 39-71-307 (3)
- Every insurer files reports of every injury or occupational disease with the Department under its rulesMCA 39-71-307 (2)
- An injury claim is compensable only if, within 30 days of the accident, the employer or insurer is told the time and place of the accident and the nature of the injury; actual knowledge by the employer, its managing agent or the superintendent in charge counts as notice (occupational diseases excepted)MCA 39-71-603 (1)
Every accident, to the insurer within 6 days
File a full and complete report of every work accident, injury or occupational disease with your insurer: the first report of injury form, within six days of notice. Employers without coverage send it to the Department, and employees may file one themselves. Refusing or neglecting the reports costs 200 to 500 dollars per offense.
The employee's 30-day notice
An injury claim needs notice to the employer or insurer within 30 days of the accident, giving the time and place of the accident and the nature of the injury. If the employer, its managing agent or the superintendent in charge already knew, that counts.
From field notes to a finished Montana report
Note the time and place, what happened, the nature of the injury, and when you were told. ReportDraft writes the incident up with those details and keeps fields for the notice and the date the first report went to the insurer.
Common mistakes
- Skipping the first report for an injury that did not cost time off.
- Sending the first report to the Department instead of the insurer.
- Waiting longer than six days after notice.
- Leaving the time or place of the accident out.
- Treating a supervisor's knowledge as not counting as notice.
