To work as a construction contractor in Montana with employees, you must register or license with the state and carry Montana workers compensation for your workers, or hold exemption certificates for any exempt owners. Montana has been moving its construction contractor program from registration to licensing, but the insurance rule is unchanged: employees mean a comp policy.
Who this is for: Montana construction contractors getting or renewing their state registration or license.
The short version
- Construction contractors register or license with the state. Montana is converting its long-standing registration program into a licensing program.
- Proof of comp is a condition. Registration or licensing requires Montana workers comp for employees, or exemption certificates for exempt owners.
- Workers comp follows the one-employee rule (section 39-71-401), license or not.
- Solo contractors have a choice. A contractor with no employees can register voluntarily and may need an exemption certificate.
- Out-of-state coverage is not accepted for construction work performed in Montana.
What Montana requires to work as a contractor
Montana splits contractor rules between the construction contractor program run by the state labor department and the separate trade licenses for electricians and plumbers. Workers comp is not an add-on to a license; it is driven by whether you have employees.
| Requirement | What it is | When it applies |
|---|---|---|
| Construction contractor registration or license | State credential to operate as a construction contractor | Contractors with employees; solo contractors may register voluntarily |
| Statewide electrician or plumber license | Trade license issued by the state board for that trade | Required to do that trade in Montana |
| Workers compensation | Insurance for on-the-job injuries to your workers | Once you have any employee (section 39-71-401) |
| General liability | Coverage for third-party property damage and injury | Not a state license rule, but commonly required by clients |
Registration, licensing, and workers comp
Historically Montana registered construction contractors rather than licensing them, and registration required proof of Montana workers comp for employees, or a valid exemption certificate for listed individuals who are not corporate officers. A 2025 law started converting that program into a licensing program with conduct and discipline standards, and the exact program name, fees, and effective dates have been in transition through 2026. What has not changed is the core rule: a construction contractor with employees must carry Montana coverage, and out-of-state coverage is not accepted for Montana construction work. Confirm the current program details with the state before you apply.
Why contractors collect certificates from subs
Two forces pull Montana contractors into coverage early and into collecting proof from others. First, general contractors and commercial clients routinely require proof of coverage before they let you on site, so a policy is often the price of the work. Second, if you hire subs, an uninsured sub can become your problem: under the statutory employer rule the state can treat that sub's crew as your employees and make you pay their comp. Engaging subs who are properly registered or licensed and collecting a current certificate or a valid exemption certificate from each one keeps that exposure off your books.
A Helena example
Illustrative, not a quote. An electrician in Helena holds a state electrical license and works as a construction contractor with three employees. Because she has employees, she needs Montana workers comp, and proof of it is part of her contractor credential, so the trade license, the contractor registration or license, and the comp policy are separate pieces that all have to be in place. Before a framing sub starts on a remodel she is coordinating, she collects the sub's certificate of coverage. See our workers comp for electricians page.
Real questions Montana owners ask
What insurance does a Montana contractor need?
A construction contractor with employees must carry Montana workers comp, and registration or licensing requires proof of it. Clients also commonly require general liability.
Does Montana license or register contractors?
Montana has long registered construction contractors and has been converting that program into licensing, but the workers comp requirement is unchanged.
Do I need workers comp for a contractor registration?
Yes, if you have employees. Proof of Montana coverage, or exemption certificates for exempt owners, is a condition of registering or licensing.
What if I am a solo contractor with no employees?
You are not required to carry comp for yourself, but you can register voluntarily and may need an exemption certificate, and clients often ask for proof.
Can I use my out-of-state policy for Montana jobs?
No. Out-of-state coverage is not accepted for construction work performed in Montana; you need Montana coverage.
Why do general contractors ask my subs for certificates?
Because an uninsured sub can become the general contractor's responsibility under the statutory employer rule, so they collect certificates to protect themselves.
Are electricians and plumbers licensed separately?
Yes. Trade licenses for electricians and plumbers are handled by their own state boards, separate from construction contractor registration.
Why Montana owners choose Morrow
- We shop the right market for you. In Montana you buy workers' comp on the open market, where private insurers compete with the state-chartered Montana State Fund, which by law must insure almost any Montana employer that asks, so we can shop your rate across carriers and still keep the State Fund as a guaranteed backstop for hard-to-place work.
- We catch pricing mistakes. Your price depends heavily on the category your work falls into for pricing (the class code). Put people in the wrong category and you overpay for years. We review your payroll and classifications before you buy.
- Proof of coverage, fast. Need a certificate (proof of coverage) for a general contractor or a landlord before Monday? We turn those around the same business day for most carriers.
- We help lower the score that drives your price. Insurers give you a score based on your past claims that raises or lowers your cost (the experience modification rate). We review it each year, flag errors, and connect you with return-to-work and safety resources that bring it down.
- Real people when a claim happens. When someone gets hurt, we stay involved through the life of the claim, not just at renewal.
