Contractor licensing

Montana contractor license requirements

Since January 1, 2026, construction contractors in Montana need a Construction Contractor License from the Department of Labor and Industry. It replaced the old registration program, with no exam, and the main condition is proof of workers' compensation compliance.

Montana now licenses construction contractors. House Bill 239 (Chapter 644, Laws of 2025) turned the state's contractor registration program into a Construction Contractor License run by the Montana Department of Labor and Industry (DLI), effective January 1, 2026. There is no trade exam for general construction. The license is about workers' compensation, unemployment insurance, and wage compliance, and it lets DLI act against fraudulent or unlicensed contractors. Electricians and plumbers are licensed separately by their own boards.

What changed in 2026

Before 2026, Montana registered contractors under Title 39. DLI's notice to registrants says every existing registration converted automatically to a contractor license on January 1, 2026, with the same expiration date. The program now falls under the uniform rules for licensed professions in Title 37, Chapter 1, Part 4, which brings standard complaint, hearing, and appeal procedures. DLI says it does not judge the quality of a contractor's workmanship when it enforces licensing complaints; enforcement covers conduct defined in law.

Failing to comply with workers' compensation, unemployment insurance, or wage laws is unprofessional conduct under the new chapter. Fines collected from construction contractors go into the state's uninsured employers' fund. Applications and renewals are online through the state's licensing portal.

Who needs a Montana contractor license

Under 37-45-201, an individual or business may not engage in business as a construction contractor without a current license from DLI. The application includes the applicant's Social Security number, proof of workers' compensation compliance, the IRS employer identification number if any, and the names of owners, partners, officers, managers or members, and the registered agent.

The exemptions in 37-45-104 are long. The ones contractors run into most:

  • Independent contractors with no employees. They are exempt but may choose to license.
  • Small jobs. Casual, minor, or inconsequential work where the aggregate contract price is less than $2,500 a job. This does not apply when the work is part of a larger operation or when a job is split into contracts under $2,500 to dodge the law.
  • Licensed electricians and plumbers working within the scope of their license, plus licensed architects, engineers, and land surveyors acting in a professional capacity.
  • Owners working on their own property, unless they build to promptly sell (with an exception for an owner who has lived there as a primary residence for the last 12 months).
  • Employees of a contractor paid wages as their sole compensation.
  • Material suppliers who do not fabricate materials into the work, and installers of finished products that do not become a permanent fixed part of a structure.

A one-person framing outfit with no employees does not need the contractor license, but it still needs either workers' comp coverage or an Independent Contractor Exemption Certificate. DLI's ICEC program charges a nonrefundable $125 application fee and requires no test. Many general contractors also ask solo subs to carry a license voluntarily, because of the liability rule below.

Why general contractors care: the liability shield

Section 37-45-202 is the part to remember when you hire a subcontractor. If you engage a contractor who is licensed on the date of the contract, you are not liable as an employer for that contractor's workers' compensation, unemployment insurance, or wages and fringe benefits. The protection covers the licensed contractor's employees and lower-tier subs hired to fulfill that contract.

Say a Bozeman builder hires an unlicensed concrete crew with two employees for a $60,000 foundation package, and one worker gets hurt. Without a license on file, the builder can end up exposed as the employer. Run the license search on the contract date, save a screenshot with the subcontract, and collect a certificate of insurance. A routine like tracking subcontractor insurance certificates catches lapses before they matter.

Local licenses, trades, and public work

Montana limits local licensing. Under 37-45-204, a political subdivision may not require or issue registrations, licenses, or bonds for the same or a similar purpose as the state program. Local governments can still charge a general business license fee that applies to all businesses, and they still handle building permits and inspections.

Public contractors face one more state rule. Montana defines a public contractor as one working on public construction where the contract exceeds $80,000, and that includes subcontractors on those contracts. Public contractors pay a license fee equal to 1 percent of gross receipts from public contracts to the Department of Revenue, computed on each separate contract. Before bidding public jobs, also read Montana prevailing wage and Montana prompt payment and retainage.

Frequently asked questions

Does Montana require a contractor license?

Yes, since January 1, 2026. Construction contractors need a Construction Contractor License from the Montana Department of Labor and Industry unless an exemption applies, such as independent contractors with no employees or jobs under $2,500 that are not part of a larger project.

Is there an exam for a Montana contractor license?

DLI's program page lists no exam for the construction contractor license. Electricians and plumbers are tested and licensed separately by their state boards.

What happened to Montana contractor registration?

HB 239 converted it to a license. Active registrations as of December 31, 2025 were converted to licenses on January 1, 2026, and DLI says expiration dates stayed the same and the cost to apply or renew did not change.

How do I look up a Montana contractor license?

Use the state's Look Up a License search at ebizws.mt.gov, linked from DLI's Construction Contractor License page. Check it on the date you sign a subcontract.

Can a Montana city require its own contractor license?

Not for the same purpose as the state license. State law bars political subdivisions from requiring similar registrations, licenses, or bonds, though cities can charge a general business license fee on all businesses.
