Do You Need a Contractor’s License in Montana?

If you run a construction business in Montana with even one employee, you need a contractor license from the Montana Department of Labor and Industry. Sole proprietors working alone don’t need the license, but they generally need an Independent Contractor Exemption Certificate instead. The license costs $70, requires proof of workers’ compensation coverage, and covers most trades that build, alter, or remove structures attached to real estate.¹

Who Has to Be Licensed

The trigger is employment. Any construction business with employees must hold a Montana contractor’s license, and the state defines construction contractor broadly: anyone who adds to or takes away from a structure, development, or improvement attached to real estate. General contractors, remodelers, roofers, siding installers, concrete workers, and most other building trades fall inside that definition.¹

A sole proprietor working alone is not required to hold the license, though they can get one voluntarily. The moment you hire your first employee, the requirement applies. The whole framework exists to make sure every construction employer carries workers’ compensation insurance.

If You Work Alone: The Independent Contractor Exemption Certificate

Sole proprietors, working partners, and working LLC members without employees have to sort out their workers’ compensation status even without the contractor license. Montana gives you two choices: buy a self-elected workers’ compensation policy that covers you personally, or obtain an Independent Contractor Exemption Certificate (ICEC).²

An ICEC is a formal waiver. You give up any right to workers’ compensation benefits if you’re hurt on the job, and in return the certificate establishes that you’re an independent contractor rather than someone’s employee. General contractors and property owners want that proof before they hire you, because a worker later reclassified as an employee creates an insurance problem for them.

The 15-Point Documentation Test

The ICEC is not a form you sign and send in. Montana runs a point-based scoring system to verify you’re actually running your own business rather than papering over an employment relationship. Applicants must submit documentation that scores at least 15 points across categories that include proof of insurance accounts, contracts showing independent contractor status, evidence of your own tools and equipment, business cards or advertising, and tax filings.³

A single document can count toward more than one category, but you’re capped at two items per category, and the department decides how many points each item earns. Applicants who can’t show they control their own schedule, supply their own tools, advertise their services, and carry real financial risk get denied.²

How to Apply

The department is rolling applications onto its online Citizen Portal, but until that system is fully live, use the current paper process. Gather these before you apply:

A Federal Employer Identification Number (FEIN). If you don’t have one, you can apply through the IRS using Form SS-4 or the online application at irs.gov, with a valid Social Security Number or ITIN for the responsible party.⁴
Proof of a valid Montana workers’ compensation policy covering your employees, whether through an authorized insurer or an approved self-insurance arrangement.⁵
Your Montana Unemployment Insurance account number.
Your legal business name and structure as filed with the Montana Secretary of State. The name on the application has to match your filings exactly.

The fee is $70, nonrefundable, and it applies to initial applications, renewals, and reinstatements. If your business’s FEIN changes for any reason, you file a new application and pay the fee again. Renewal paperwork goes out from the department about 60 days before your license expires.⁶

A Note on the 2026 Change

If you’re looking at older guidance that calls this a “construction contractor registration,” that’s the same thing. Montana repealed the older registration statute under Title 39, Chapter 9 effective January 1, 2026, and moved oversight into the professional licensing framework under Title 37.⁷ Active registrations converted to licenses automatically, expiration dates carried over, and the fee did not change.⁸ The main practical upgrade is standardized due process if the state files a complaint against you.

Electricians and Plumbers Need a Separate License

The general contractor’s license doesn’t cover electrical or plumbing work. Both trades have their own boards and their own licensing rules, and an electrical or plumbing business with employees needs the trade license and the general contractor’s license.

Electricians

The State Electrical Board issues journeyman and residential licenses under Title 37, Chapter 68. A journeyman license requires either completion of an approved apprenticeship or 8,000 hours of practical experience, plus a written exam of at least 60 questions on the National Electrical Code and Montana board rules. A residential license requires 4,000 hours on structures with fewer than five living units and a 50-question exam.⁹

Licensed electricians have to carry the license on the job. If a building inspector, department employee, or the person professionally responsible for the site asks to see it, you produce it. Failing to show your license to a department employee can trigger an on-the-spot citation.¹⁰

Plumbers

The Board of Plumbers issues journeyman and master licenses. Journeyman applicants need five years of field experience or completion of an approved apprenticeship. Master applicants need four more years as a licensed journeyman, with at least three of those years either working under a master plumber or in a supervisory role. Montana has journeyman reciprocity with Oregon, Idaho, North Dakota, and South Dakota for plumbers who have passed both written and practical exams in those states.¹¹

Insurance

Workers’ compensation is what the whole license really turns on. Every Montana employer has to provide it, either through an authorized insurer or under a self-insurance arrangement approved by the department, and without proof of coverage you can’t hold the license.⁵

General liability insurance is a separate matter. Montana doesn’t require it for the contractor license, but many clients and general contractors won’t hire a subcontractor without it. Annual premiums for small contracting businesses typically run around $2,500 to $3,500, with higher-risk trades paying more.

What the State License Doesn’t Cover

A Montana contractor license is not a full compliance package. Two federal rules and one local layer sit outside it and catch contractors who assume the state license is enough.

If you do renovation, repair, or painting work on housing built before 1978, EPA’s Renovation, Repair and Painting program requires firm certification. Montana doesn’t run its own version, so EPA administers it directly here. Firm certification is $300, lasts five years, and requires every worker disturbing painted surfaces to hold individual renovator certification or to have been trained by a certified renovator. That applies to sole proprietors, too.¹²

OSHA’s fall protection standard also applies statewide. Any employee working six feet or more above a lower level has to be protected by a guardrail, safety net, or personal fall arrest system.¹³ Fall protection is one of OSHA’s most-cited standards and one of the fastest ways to earn a federal penalty on a roofing, siding, framing, or any elevated job.

Local permits are the other missing piece. Cities and counties in Montana commonly require their own business licenses, building permits, or both, and the requirements and fees vary. Call the local building department or city clerk before starting any project. Skipping a local permit is a common route to a stop-work order.

Penalties for Working Without a License

Montana can fine construction contractors up to $500 per violation for working without a license, working with a suspended license, or transferring a license to another person.¹ Per-violation means the numbers stack if you’re running several jobs at once. Working unlicensed also weakens your ability to enforce contracts and collect payment, and license status is public: clients check.

For electricians, department employees have authority to inspect active job sites and issue citations if you can’t produce your license on request.¹⁰ The dollar figures on a single citation may not be the largest cost. A violation on your record makes bids harder to win in a construction community where reputation travels quickly.
