Montana (MT) Trucking Compliance: Filings, Registrations & Permits
✦ The quick answer
Montana-based motor carriers must keep their federal filings current (USDOT/MCS-150, UCR, IFTA, IRP, and Form 2290 HVUT) and handle apportioned registration, the state Gross Vehicle Weight (GVW) fee, fuel and trip permits, and oversize/overweight permits through the Montana Department of Transportation (MDT) Motor Carrier Services Division. Montana has no general sales tax and no separate weight-distance or highway-use mileage tax, so IFTA fuel reporting plus apportioned registration and the GVW fee cover most carriers.

What Montana requires
UCR
The Unified Carrier Registration (UCR) is an annual federal program administered by the states, and Montana participates. If you operate commercial motor vehicles in interstate commerce, you must register and pay the UCR fee every year. Your fee bracket is based on the total number of power units (trucks and tractors) in your fleet, not a flat per-truck rate. UCR registration opens in the fall for the upcoming calendar year, and enforcement typically begins January 1. Brokers, freight forwarders, and leasing companies without trucks pay the smallest bracket. We help you confirm your correct fleet-size bracket, prepare an accurate registration, and validate the details before you submit through the official UCR system. Always verify the current-year fee amounts on the official UCR site, since the brackets are set annually.
Form 2290 (HVUT)
Form 2290 and the Heavy Vehicle Use Tax (HVUT) are federal, filed with the IRS, but they matter in Montana because the state will not register or renew a qualifying heavy vehicle without proof of payment (a stamped Schedule 1). HVUT applies to vehicles with a taxable gross weight of 55,000 lbs or more. The tax for a vehicle at 55,000 lbs is $100, plus $22 for each additional 1,000 lbs over 55,000, up to a maximum of $550 for vehicles at 75,000 lbs and above. The HVUT period runs July 1 through June 30. For vehicles in use at the start of the period in July, the deadline to file is August 31. For a newly acquired or first-used vehicle, the deadline is the last day of the month after the month you first put it on the road. We help you calculate the correct taxable gross weight, prepare Form 2290, and validate your entries so your Schedule 1 comes back clean for your Montana registration.
MCS-150
Your USDOT number and the MCS-150 form are how FMCSA tracks your carrier identity, fleet size, mileage, and operation type. Every interstate carrier and many intrastate Montana carriers need a USDOT number, and the MCS-150 must be updated at least every two years (the biennial update) on a schedule tied to your USDOT number. Missing the biennial update can deactivate your USDOT number and put your operating authority at risk. Montana intrastate carriers may also be required to carry a USDOT number under state rules. We help you keep your MCS-150 accurate (mileage, power-unit count, contact details), guide you through the biennial update timing based on your USDOT number, and validate the data before you file it with FMCSA.
IFTA
Montana is a member of the International Fuel Tax Agreement (IFTA). If you operate qualified motor vehicles across state lines, you base your IFTA license in Montana (your base jurisdiction) and file a single quarterly fuel tax return covering all member states and provinces. A qualified vehicle generally has two axles and a gross weight over 26,000 lbs, three or more axles regardless of weight, or is used in combination over 26,000 lbs. You get Montana IFTA decals and a license, then report total miles and fuel purchased per jurisdiction each quarter so taxes net out correctly. Quarterly returns are due the last day of the month following each quarter: April 30, July 31, October 31, and January 31. Montana IFTA is administered through the Montana Department of Transportation, and you must keep detailed mileage and fuel records. We help you organize trip and fuel data, calculate your quarterly figures, and validate the return before you file it with the state.
IRP
The International Registration Plan (IRP) lets you register your trucks once in Montana and get apportioned plates that are valid in all member jurisdictions, with registration fees split based on the miles you run in each state or province. Montana IRP is handled by the Montana Department of Transportation (MDT) Motor Carrier Services Division. You'll report your fleet's distance by jurisdiction (actual miles for renewals, or estimated miles for a brand-new operation), and your Montana apportioned credentials and cab card list every jurisdiction you're authorized to run in. IRP and IFTA are separate programs but both rely on accurate mileage records, so good recordkeeping serves both. We help you assemble your jurisdiction mileage, prepare your IRP application or renewal, and validate it before you submit to MDT.
Permits
Beyond the core federal programs, Montana carriers may need state-specific credentials from the Montana Department of Transportation (MDT) Motor Carrier Services. Trucks not based in Montana or not yet apportioned can buy temporary trip permits and temporary fuel permits to move legally through the state instead of carrying full IRP/IFTA credentials. Montana also assesses a Gross Vehicle Weight (GVW) fee on commercial vehicles, which can be paid annually as part of registration or covered through trip permits for occasional travel. Oversize or overweight loads require an MDT oversize/overweight permit, and certain dimensions, weights, or routes need additional review, routing, or escort. Montana has seasonal load restrictions and special-route considerations as well. We help you identify which Montana permits and fees apply to your operation, prepare the paperwork, and validate it. Always confirm current requirements and fee amounts directly with MDT before you rely on them.
Montana-specific requirements
Montana stands out for what it lacks and the fee it keeps. There is no general state sales tax in Montana and no separate weight-distance or per-mile mileage tax layered on top of IFTA, unlike New Mexico, Kentucky (KYU), New York (HUT), and neighboring Oregon. What Montana does have instead is the Gross Vehicle Weight (GVW) fee, a state fee assessed on commercial motor vehicles based on the registered or declared gross weight; it can be paid annually with your registration or covered through trip permits for vehicles passing through occasionally, so plan for it as a real Montana-specific cost. Motor Carrier Services within the Montana Department of Transportation administers IRP, IFTA, GVW, oversize/overweight permits, and trip/fuel permits, and MDT operates weigh stations and inspection sites where credentials, 2290, size, and weight are checked. Montana issues intrastate operating authority and registers intrastate carriers at the state level. Because Montana borders Idaho, Wyoming, North Dakota, South Dakota, and the Canadian provinces of Alberta, British Columbia, and Saskatchewan, carriers running north often deal with Canadian IRP/IFTA jurisdictions, and those crossing into Oregon must still handle Oregon's separate weight-mile tax even though Montana charges no mileage tax of its own.

Frequently asked questions
Does Montana have a weight-distance or highway-use tax?+
No. Montana does not charge a separate per-mile weight-distance or mileage tax on top of your quarterly IFTA return. Montana does assess a Gross Vehicle Weight (GVW) fee on commercial vehicles based on registered weight, which is different from a per-mile tax. If you run into Oregon, New Mexico, Kentucky (KYU), or New York (HUT), you must still file and pay those states' weight-distance taxes for the miles you run there. Always verify current rules with each state.
What is the Montana GVW fee?+
The Gross Vehicle Weight (GVW) fee is a Montana state fee on commercial motor vehicles based on the registered or declared gross weight of the vehicle or combination. You can pay it annually as part of your Montana registration or, for occasional trips through the state, cover it through a trip permit. The exact amount depends on your weight bracket, so confirm the current fee with the Montana Department of Transportation Motor Carrier Services.
How much is the Form 2290 Heavy Vehicle Use Tax?+
For a vehicle with a taxable gross weight of 55,000 lbs, the HVUT is $100. Add $22 for each additional 1,000 lbs over 55,000, up to a maximum of $550 for vehicles at 75,000 lbs or more. The tax period runs July 1 to June 30, and the filing deadline for vehicles used in July is August 31. Montana needs your stamped Schedule 1 to register the vehicle.
What do I need to drive through Montana if my truck isn't registered there?+
If your truck doesn't carry Montana apportioned (IRP) plates or an IFTA license, you generally need to buy a temporary trip permit and a temporary fuel permit, and cover the Gross Vehicle Weight (GVW) fee, before running Montana miles. Montana weigh stations and inspection sites check these credentials, so it's best to have them before you cross. We can help you understand which permits and fees apply.
When are my Montana IFTA returns due?+
IFTA fuel tax returns are due quarterly: April 30, July 31, October 31, and January 31 for the preceding quarter. You file one return through the Montana Department of Transportation covering all member jurisdictions. Keep detailed mileage and fuel-purchase records, because that data drives the return.
Is QuickTruckTax a filing service that submits my forms?+
