Starting and Operating a Trucking Business in Montana

Starting a trucking company in Montana requires compliance with both federal mandates and Treasure State specific regulations overseen by the Montana Department of Transportation (MDT). The process begins with establishing a legal business entity through the Montana Secretary of State, which currently charges a $70 filing fee for a Domestic Limited Liability Company (LLC). Beyond entity formation, carriers must secure a USDOT number and, if crossing state lines, Federal Operating Authority (MC number) through the FMCSA. Montana is a key transit corridor for the I-15 and I-90 interstates, making strategic planning around weight limits and seasonal restrictions vital for new entrants. Compliance involves registering for the International Registration Plan (IRP) and International Fuel Tax Agreement (IFTA) if your vehicles exceed 26,000 pounds Gross Vehicle Weight (GVW). Using DispatchTool, Montana carriers can automate the collection of GPS data and state-line crossings required for quarterly IFTA filings. The platform generates reports based on actual miles driven on Montana highways versus out-of-state routes, reducing the manual burden of trip sheet management. Create a DispatchTool account to start tracking your Montana-based fleet expenses and mileage for tax compliance.

Secretary of State and Business Licensing

Before applying for motor carrier authority, you must register your business with the Montana Secretary of State. Most owner-operators choose an LLC structure to protect personal assets. The filing fee is $70, and you must appoint a registered agent with a physical Montana address. After formation, you must apply for an Employer Identification Number (EIN) from the IRS, which is free and required for opening business banking accounts and hiring drivers. Montana does not have a general state business license, but individual municipalities like Billings or Missoula may have local requirements.

Federal DOT and Motor Carrier Authority

Every commercial motor vehicle (CMV) with a GVW over 10,001 pounds must have a USDOT number. If you intend to haul for-hire freight across state lines, you must apply for Interstate Operating Authority (MC Number) via the FMCSA Unified Registration System. This process includes a $300 filing fee. Once the application is submitted, a 10-day protest period occurs before the authority becomes active. During this time, you must file proof of insurance (Form BMC-91 or BMC-91X) and designate a process agent via Form BOC-3.

Montana MDT Intrastate Requirements

For carriers operating exclusively within Montana borders (intrastate), you must still register with the MDT Motor Carrier Services (MCS) division. While Montana has deregulated much of its intrastate trucking, certain commodities like household goods or passengers still require a Class E or Class B Certificate of Compliance. All intrastate carriers must adhere to the safety regulations outlined in the Montana Code Annotated (MCA) Title 61, Chapter 10, which governs vehicle size, weight, and load configurations on state highways.

Heavy Vehicle Use Tax and IFTA Registration

Vehicles weighing 55,000 pounds or more must pay the Federal Heavy Vehicle Use Tax (Form 2290), which ranges up to $550 per year. Following this, you must register for IFTA through the Montana Department of Transportation if you operate in two or more jurisdictions. Montana’s current tax rate for diesel is $0.2975 per gallon. IFTA stickers must be renewed annually for a $1.00 fee per set, and reports must be filed quarterly, even if no interstate miles were driven during that period.

International Registration Plan (IRP) in Montana

Montana belongs to the International Registration Plan, which allows for the distribution of registration fees based on the percentage of miles driven in each state or province. Registration is managed through the MDT MCS division. Fees are calculated based on the vehicle's age, weight, and the specific jurisdictions traveled. For a new 80,000-pound tractor-trailer combo, initial registration costs often exceed $1,500. You must provide a proof of Montana residency, such as a utility bill or property tax receipt, to establish your base jurisdiction.

Insurance Minimums and Liability Coverage

The FMCSA requires a minimum of $750,000 in Primary Auto Liability insurance for general freight carriers. However, most shippers and brokers require a $1,000,000 limit before they will tender a load. If hauling hazardous materials, this requirement jumps to $5,000,000. Montana law also requires all employers, including trucking companies with one or more employees, to carry Workers' Compensation insurance. Cargo insurance is not federally mandated for all carriers but is standard at $100,000 per occurrence in the industry.

Unified Carrier Registration (UCR)

Montana participates in the Unified Carrier Registration agreement. This is an annual fee paid by all interstate motor carriers, private carriers, and brokers. The fees are based on the total number of commercial vehicles in your fleet. For 2024-2025, the fee for a fleet of 0-2 vehicles is approximately $37, while fleets of 3-5 vehicles pay roughly $111. Failure to pay the UCR can result in fines and the impounding of vehicles if caught by Montana Highway Patrol during a roadside inspection.
