General Business License
Montana does not have a statewide general business license.

Montana has no sales tax, which simplifies business registration. Some Montana cities and counties require local business licenses. The state's outdoor economy and tourism industry influence many licensing requirements.

Next Steps to Launch Your General Contracting Business

Form your LLC or corporation in Montana — general contractors carry significant liability for subcontractor work and project defects (filing fee: $35)
- 2
Obtain your Montana general contractor license — requires experience documentation, exam, and financial statements in most states
- 3
Obtain a contractor surety bond and general liability insurance — bond requirements vary by state and the GL premium is typically a meaningful four-figure annual cost; both are required for most permits and contracts
- 4
Complete OSHA 30-Hour Construction Safety training — required by most commercial project owners and insurance carriers
- 5
Register with Montana Contractor State License Board or equivalent regulatory agency and maintain license with required continuing education
- 6
Build a subcontractor network: licensed plumbers, electricians, HVAC techs, and framers — GCs depend on reliable subs for project quality
- 7
Create a construction contract template using AIA or AGC contract forms covering scope, payment schedule, change orders, and warranty
- 8
Get workers' compensation insurance before hiring any employees or subcontractors — Montana requires WC for all construction workers
