Getting your Montana license starts here...
Getting a Montana contractor license starts with understanding that Montana doesn’t test or license general contractors the way most states do. Instead, the Department of Labor and Industry requires a $70 Construction Contractor Registration for businesses with employees, or a $125 Independent Contractor Exemption Certificate for solo operators — no exam required either way. Electricians and plumbers, however, hold true state licenses with written exams through their own boards.
Contractor Licensing Inc. has helped Montana contractors navigate this registration-based system for years — from choosing between Construction Contractor Registration and an exemption certificate, to preparing for the electrical or plumbing exam, to understanding Montana’s NERA reciprocity agreements if you’re licensed elsewhere. Whether you’re a general contractor, electrician, or plumber, we handle the paperwork so you can focus on the job.
Montana Contractor License Requirements & Application Help
Montana doesn't license general contractors the way most states do. Instead, the Department of Labor and Industry (DLI) runs a registration system tied to workers' compensation compliance — Construction Contractor Registration (CR) for businesses with employees, or an Independent Contractor Exemption Certificate (ICEC) for solo operators. Electricians and plumbers, by contrast, hold real state-issued licenses with written exams.
Contractor Licensing Inc. helps you register correctly and, if you're in a licensed trade, prepare for the electrical or plumbing exam.
Quick Answer
- No general contractor exam or competency test — just a $70 registration if you have employees.
- Solo contractors without employees can instead file a $125 Independent Contractor Exemption Certificate.
- Electricians and plumbers hold true state licenses with written exams — a completely different track.
- Montana is a NERA member, with journeyman electrical reciprocity across 13 states.
- No statewide bond requirement for general contractors.
- Unlicensed electrical or plumbing work is a misdemeanor with real jail-time exposure.
Registration, Not a License
Construction Contractor Registration (CR)
Required under MCA Title 39, Chapter 71 for any person or business with employees performing construction work. Corporations and manager-managed LLCs must register regardless of employee count. Costs $70 (non-refundable), valid for two years. No exam, experience requirement, or competency test.
Independent Contractor Exemption Certificate (ICEC)
For self-employed contractors without employees who want to opt out of workers' compensation coverage. Costs $125. Requires satisfying Montana's two-prong independent-contractor test under MCA 39-71-417 (control + independently established business).
Electrical & Plumbing — Real State Licenses
Electrical (MCA Title 37, Ch. 68)
Master, Journeyman, Residential, and Electrical Contractor license levels through the Montana State Electrical Board. Written exam required: 60 questions, 3-hour time limit, 75% to pass. Application fee $240, plus a $75 PSI exam fee.
Plumbing (MCA Title 37, Ch. 69)
Master, Journeyman, and Medical Gas licenses through the Montana Board of Plumbers. Written exam required, 70% minimum score. Candidates who fail 3 exams within a year must complete 20 hours of approved continuing education before retesting.
Boiler Operators
A separate state-level license administered by DLI's Business Standards Division alongside electrical and plumbing.
Elevator & Manufactured Dwelling
Also licensed at the state level under the same division that oversees electrical and plumbing.
Montana Contractor License Reciprocity
Electrical — NERA Member State
Montana is an active member of the National Electrical Reciprocal Alliance (NERA). Journeyman electricians can get a Montana license by endorsement, without an exam, if licensed by examination in: Alaska, Arkansas, Colorado, Minnesota, Nebraska, New Hampshire, New Mexico, North Dakota, Oklahoma, South Dakota, Texas, Utah, and Wyoming — provided the license has been held at least one year.
Montana can also grant Licensure by Endorsement to additional states found "Substantially Equivalent" on a case-by-case basis, even outside the core NERA list — confirm your specific state directly with the Board.
Plumbing — Four States
Montana recognizes journeyman plumber licenses from Oregon, Idaho, North Dakota, and South Dakota — a shorter list than electrical, so don't assume your state qualifies just because it works for electrical reciprocity.
What Happens if You Skip Registration
Montana enforces its two-track system with real penalties. A construction contractor found working without registration faces a $500 fine per occurrence. Performing electrical or plumbing work without the proper state license is a misdemeanor, carrying a fine of $250 to $1,000 and a possible jail term of 90 days to one year.

Montana Contractor Bonds
Montana has no statewide contractor license bond requirement, and we don't currently have any Montana bonds in our database — which matches the state's registration-only approach to general contracting. Some private clients, lenders, or specific municipalities may still ask for a surety bond on a project-by-project basis.

Montana Contractor Reciprocity
Montana’s **CCR** is a state registration, not a license, and the ERD does **not** offer reciprocity. Contractors performing work in Montana must complete CCR and meet coverage requirements. Any reciprocity or endorsement for state-licensed trades (such as electrical or plumbing) is handled by the respective boards.
