Workers’ Compensation Insurance Requirements in Montana
Montana contractors work in a state where workers’ comp isn’t optional at any headcount — one employee triggers the requirement. With Montana ranked 14th nationally for overall premium cost and trades like plumbing and electrical running well above the median, roofers, electricians, and plumbers need coverage that’s priced right and compliant from day one.
Montana Workers’ Compensation Legal Requirements
Under the Montana Workers’ Compensation Act (Title 39, Chapter 71, MCA), every employer — full-time, part-time, seasonal, or occasional labor included — must carry coverage starting with the first employee.
- Coverage is mandatory from the 1st employee hired, with no small-business exemption
- Narrow exemptions exist for certain agricultural workers and qualifying sole proprietors who file for exempt status
- Uninsured employers face fines of double the unpaid premium (minimum $200), additional penalties up to $1,000 plus $100/day of continued noncompliance, and lose the exclusive-remedy protection that normally limits injury liability
- Independent contractors working away from their own fixed business location — which covers most construction trades — must hold a Montana Independent Contractor Exemption Certificate (ICEC) or be treated as an employee for WC purposes
How Montana’s Workers’ Comp System Works
System type: Competitive State Fund
Montana isn’t a monopolistic state — Montana State Fund (MSF) is a competitive, nonprofit public-corporation insurer that competes with private carriers rather than holding exclusive control. Montana ranks 14th of 51 states/DC on Oregon DCBS’s 2024 premium rate study, with an index rate of 1.34, meaning premiums run about 22% above the national median — a real cost factor for contractors budgeting labor overhead.
How Montana’s Rates Compare by Trade
| Trade (NCCI Class Code) | National Rank (of 51) | Rate per $100 of Payroll |
|---|---|---|
| Roofing (Class 5551) | 37th of 51 | $4.31 |
| Electrical Wiring (Class 5190) | 7th of 51 | $3.22 |
| Plumbing NOC (Class 5183) | 7th of 51 | $3.92 |

Filing a Workers’ Comp Claim in Montana
An injured employee must report the injury to their employer within 30 days. The employer then completes a First Report of Injury or Occupational Disease (FROI), with state guidance recommending same-day filing and a legal deadline of 6 days after notice, submitted to the insurer or Montana State Fund online, by phone, fax, or mail. The insurer has 30 days to accept or deny the claim.
Penalties for Non-Compliance
Operating without coverage in Montana exposes an employer to fines of double the unpaid premium (minimum $200), added penalties up to $1,000 plus $100 per day of continued noncompliance, and full personal liability for an injured worker’s medical and wage-loss costs since the exclusive-remedy shield no longer applies (Montana DLI Uninsured Employers Fund).

How Much Does Workers’ Comp Insurance Cost in Montana?
Montana ranks in the upper half of states nationally for WC premium cost, and rates vary sharply by trade. Roofing carries higher risk pricing than electrical or plumbing work, even though Montana’s roofing rank is relatively moderate compared to other states.
| Trade | Estimated Cost per $100 Payroll | What Drives It |
|---|---|---|
| Roofing | $4.31 (per the Oregon study’s Class 5551 rate) | Fall-hazard exposure and claims severity for roof work |
| Electrical | $3.22 (Class 5190) | Shock/arc-flash risk and licensing-tied experience mods |
| Plumbing | $3.92 (Class 5183) | Confined-space and strain/injury claims history |
What Moves the Price Up or Down
- Whether you carry an ICEC for subs or classify them as employees
- Your experience modification factor built from past claims history
- Total insured payroll across all trade classifications on the job
- Choice between Montana State Fund and competing private carriers

Frequently Asked Questions
Does a Montana contractor with just one employee need workers’ comp?
Yes. Montana law requires coverage starting with the very first employee, full-time, part-time, seasonal, or occasional — there’s no small-employer exemption.
Can a Montana subcontractor avoid carrying workers’ comp?
Only if they hold a valid Independent Contractor Exemption Certificate (ICEC) from the Montana Department of Labor & Industry. Without one, a sub working away from their own fixed place of business is generally treated as an employee for WC purposes.
Is Montana State Fund the only option for coverage?
No. Montana State Fund is a competitive nonprofit insurer, not a monopoly — employers can also buy from private carriers or qualify for self-insurance.
What happens if a Montana employer is caught without coverage after a workplace injury?
The employer becomes personally liable for the injured worker’s full medical and wage-loss costs, loses exclusive-remedy protection from lawsuits, and faces fines of double the unpaid premium plus daily penalties.
Workers’ compensation requirements can change — verify current rules with the Montana Department of Labor & Industry before making coverage decisions.
