Montana Business License and Permit Requirements for Contractors

What Montana requires at the state level

For a contracting business with employees, the state-level list is short and specific. First, the entity, if you are trading as anything other than a sole proprietor under your own name: the Secretary of State's fee schedule lists Articles of Organization for a domestic LLC at $35.00, Articles of Incorporation for a profit corporation at $35.00, and Registration of an Assumed Business Name at $20.00. Second, the construction contractor licence from the Department of Labor and Industry at $70, valid two years. Third, an Independent Contractor Exemption Certificate at $125 for each working owner not personally covered by a Montana workers' compensation policy. Fourth, the tax and payroll accounts if you will pay wages.

The construction contractor licence is the one people mean when they say "contractor's licence", and since January 1, 2026 that is genuinely what it is. MCA 37-45-201(1) provides that "An individual or business entity may not engage in business as a construction contractor without a current license from the department", and lists what the licence record must contain: the applicant's social security number, proof of compliance with workers' compensation laws, the internal revenue service employer identification number if any, and the names and addresses of partners, the owner, corporate officers and registered agent, or the limited liability company's manager or members and registered agent, according to structure.

What is deliberately not on that list is a statewide general business licence. No reachable official Montana page publishes one, and we are not going to assert its absence more strongly than that. The specific licence obligations that do exist are trade licences, and the Business Standards Division publishes the complete index of the boards and programmes that issue them.

• Entity filing with the Secretary of State, if you use an entity or a trade name.
• Construction contractor licence from DLI: $70, two-year term, required once you have employees.
• Independent Contractor Exemption Certificate: $125, two-year term, for working owners without personal coverage.
• Trade licence from the relevant board, if your work is electrical, plumbing, elevator, fire protection or similar.
• Building permit from the local certified programme, or from the state where there is none.
• Withholding and unemployment insurance accounts, once you pay wages.

What a Montana city or county can and cannot add

Montana wrote the answer into the statute, which is unusually helpful. MCA 37-45-204 provides that the chapter's provisions "relating to the registration or licensing of a person, firm, or corporation, including the requirement of a bond with the state of Montana named as obligee and the collection of a fee, are exclusive for registered construction contractors", and that "A political subdivision of the state may not require or issue any registrations, licenses, or bonds for the same or a similar purpose."

The section then preserves two things for local governments. It "does not limit or abridge the authority of a local government to levy and collect a general and nondiscriminatory license fee levied upon all businesses", and it "does not limit the authority of a local government with respect to contractors not required to be registered under this chapter." So a city-wide business licence fee that applies to every business in town is not preempted, and the smallest exempt operators are outside the shield entirely.

One drafting detail is worth flagging rather than glossing. That section refers in passing to "the requirement of a bond with the state of Montana named as obligee" as one of the things the chapter makes exclusive, but no section of chapter 45 actually imposes a bond, and no reachable DLI page publishes a bond amount for the construction contractor licence. We are therefore not stating a Montana contractor bond figure anywhere. If a project owner or a general contractor asks you for a bond, that is a contract requirement, not a licensing one.

We have not opened any Montana city or county source for this article, so no municipal fee, form or deadline is stated anywhere here. What 37-45-204 gives you is the right question to ask your city hall: not "do you have a contractor licence" but "do you levy a general business licence fee on all businesses, and do you run a certified building code programme".

Permits: the part that genuinely varies by jurisdiction

DLI describes the split directly. Its Building Codes Program "establishes and enforces statewide codes by issuing permits and performing inspections", covering building, plumbing, electrical and mechanical permitting plus the elevator and boiler programmes, and it also administers the Factory-Built Building and Underground Facility Protection Programs. The department states that the programme "is responsible for adopting a uniform state building code, which is enforced statewide for residential and commercial buildings across Montana."

On top of that uniform code sits an opt-in. DLI states that "In Montana, cities, counties and towns have the option to enforce local building, electrical, plumbing, and mechanical codes, all or in part (except for state-owned agencies, which must be permitted through this Department)", that "These local building code enforcement programs must be certified by the BC Program", and that jurisdictions which have not opted in "fall under the jurisdiction of the BC Program." The department also states that "The local legislative body of a city, county or town may adopt a building code by ordinance to apply to the city, county or town jurisdictional area", and that such a code "may include only codes adopted by the Building Codes Bureau".

That last clause is the practical protection for a contractor working across jurisdictions: a certified local programme is enforcing the same adopted codes, not a different set of technical rules. The variable is who issues the permit and who inspects. DLI publishes an online permit portal at EBIZ.MT.GOV and an inspection areas page for finding the inspector responsible for a given part of the state.

The trade credentials that sit alongside the contractor licence

Montana carves the licensed trades out of the contractor chapter rather than folding them in, which is the statute's way of telling you they are governed separately. MCA 37-45-104 exempts licensed electricians and plumbers "operating within the scope of the license", fire suppression and fire protection equipment licensees under Title 50 chapter 39, water well contractors licensed under Title 37 chapter 43, licensed architects, engineers and land surveyors acting solely in a professional capacity, and licensed contract security companies under Title 37 chapter 60.

The Business Standards Division's index of professional boards and programmes is the authoritative list of what Montana actually licenses. The construction-relevant entries are the State Electrical Board, the Board of Plumbers, the Elevator Contractors, Mechanics and Inspectors Licensing Program, the Fire Protection License Program, the Home Inspector Program, the Construction Blaster Program, the Crane and Hoisting Operator Program, the Boiler Operator Program, the Board of Architects and Landscape Architects, the Board of Professional Engineers and Professional Land Surveyors, the Board of Sanitarians and the Private Security Program. If your trade is not on that index and not covered by the contractor licence, Montana does not issue a credential for it.

Two of those boards publish requirements worth planning around. The State Electrical Board requires a "Montana Licensed Master Electrician is responsible party for the business" for an Electrical Contractor licence, plus proof of compliance with Montana workers' compensation and unemployment insurance or an Independent Contractor Exemption, and publishes no fee on that page, only "(see application)". The Board of Plumbers states that FY 26 renewals "open July 2, 2026, and are due by September 1, 2026", that the renewal fee "is 100% abated; however, if you are renewing late, fees do apply", and that licensees must comply with ARM 24.180.2102, which requires "4 hours of continuing education completed during renewal cycle".

Tax registrations that behave like licences

Montana spares contractors the seller's permit that dominates setup in most states, because the Department of Revenue states that "Montana does not have a general-use sales tax." There is no sales tax licence to obtain, renew or display.

The tax that does apply to contractors specifically is narrow and applies only to public work. The department states that "All contractors and subcontractors must pay a 1% tax on all public construction contracts over $80,000", and describes the collection mechanism: "Contractors and subcontractors shall pay or have withheld from their earnings a 1% tax on all construction work for a public agency with a total contract value greater than $80,000." Usually the awarding public entity registers the contract "within 10 days after the contract is awarded" and files returns and remits "within 30 days after the date of a payment to a contractor". Contractors can then request a refund for business personal property taxes and certain registration fees for vehicles used in the contracting business, or claim a credit on their Montana income tax return.

If you will pay wages, the withholding account is effectively a registration you cannot skip. The department states that you need one if you issue Montana wages, issue Forms W-2 with or without withholding, or issue Forms 1099 with withholding, and that registration is either online through the TransAction Portal or by mail on Form GenReg. The unemployment insurance account is separate again and sits with DLI's Unemployment Insurance Division, which publishes an Employer Handbook covering "subjectivity requirements, how to register your business, quarterly report filing and payment requirements, understanding your tax rate, and more."

Read Montana pages with the January 2026 change in mind

Montana rewrote this area of law in 2025 and the agency web pages are catching up unevenly. The clearest example: DLI's contractor page still defines the regulated activity by citing "(39-9-102, MCA)". Open that section on the Legislature's own site and it reads "Repealed. Sec. 14, Ch. 481, L. 2025. (Repealer effective January 1, 2026.)" The operative definition has been 37-45-102 since January 1, 2026. The substance is close, but the citation you would copy into a contract or a bid is dead.

The Commissioner's own HB 239 notice does the same thing in the other direction, telling readers that the exemptions are "currently found in MCA 39-9-211" when they now sit at 37-45-104. And DLI's Independent Contractor Exemption Certificate page still carries the sentence "Montana state government does not license construction contractors", which was true before January 1, 2026 and is contradicted by 37-45-201 and by the Commissioner's notice after it.

None of this means the department pages are useless. The fee, the two-year term, the documents to attach and the process are all published there and nowhere else. It means you should take procedure from DLI and take law from the Montana Code Annotated, and never assume a page you found through a search engine has been updated since the change.

Check the official page yourself before you file or sign

Montana splits contractor rules across at least four places: the Employment Relations Division of DLI for the contractor licence and the exemption certificate, the Business Standards Division for the electrical, plumbing, elevator, fire protection and home inspector credentials, the Secretary of State for the entity and the annual report, and the Department of Revenue for withholding and the contractor's gross receipts tax. No single page carries all of it.

Two more moving parts make a fresh check worth the ten minutes. The Commissioner has announced that "Starting mid-August 2026, both processes will move fully online", that "paper applications and renewals will be discontinued once the new system launches", and that applicants should "discard any old forms, as they will no longer be accepted." And DLI's own website and lookup tools were scheduled for an August update at the same time. If you are reading this after mid-August 2026, the form you downloaded may already be void.

DLI publishes a single number for both the contractor and the exemption certificate programmes, (406) 444-7734. Call it before you post a cheque, and keep a dated copy of whatever page you relied on.
