The International Registration Plan (IRP) is a cooperative agreement between the 48 contiguous U.S. states, the District of Columbia, and most Canadian provinces. It allows commercial motor carriers to operate across multiple jurisdictions using a single registration and apportioned license plate issued by their base state.
If you're a commercial carrier based in Montana and your operations take you beyond state lines, IRP registration is required. The fees you pay under IRP are distributed proportionally to each state or province where your vehicle travels, based on the miles driven in each jurisdiction during a reporting period. This system helps ensure fair revenue sharing among states while simplifying compliance for carriers.
Who Needs to Register for IRP in Montana?
Your vehicle qualifies for IRP if it travels in two or more IRP jurisdictions, is used to transport goods or passengers, and meets any of the following conditions:
- Has two axles and a gross vehicle weight (GVW) over 26,000 pounds
- Has three or more axles, regardless of weight
- Is used in combination (such as a truck and trailer) with a combined GVW over 26,000 pounds
Vehicles that do not meet these conditions, or that only operate within Montana, are not subject to IRP registration. Recreational vehicles, government-owned vehicles, and those with restricted plates (like farm-use tags) are typically exempt from IRP requirements.
Documents for IRP in Montana
To apply for IRP in Montana, you’ll need to gather several documents before beginning the process. These include proof of ownership or lease, a current Form 2290 showing payment of the federal Heavy Vehicle Use Tax if your vehicle is over 55,000 pounds, and evidence of Montana residency such as a utility bill or business license. You’ll also need to provide your USDOT number, an updated MCS-150 form, and valid proof of insurance.
If you’re renewing or transferring an IRP registration, mileage reports showing the number of miles traveled in each jurisdiction during the prior reporting period are required. If someone is filing on your behalf, a notarized Power of Attorney will also be needed. Finally, you must complete and sign the Montana IRP application and fleet signature page.
How to Apply for IRP
Once you’ve gathered all required documentation, the next step is to submit your application to the Montana Motor Carrier Services (MCS) office, located in Helena. You can do this in person or by using the state’s online ePART portal. First-time registrants must create an IRP account, which MCS staff will activate upon review of your application.
After your account is active and your documents are approved, MCS will calculate your IRP fees. These fees are based on the jurisdictions you intend to operate in and the percentage of miles expected in each. Once you’ve paid, you will receive your apportioned license plate and cab card. The cab card lists every state or province in which your vehicle is registered to operate under IRP.
For new carriers without prior mileage history, Montana may assign estimated distances based on the IRP Average Per-Vehicle Distance (APVD) chart.
IRP Renewal in Montana
IRP accounts must be renewed on an annual basis. Renewal notices are typically issued 30 to 60 days before your account expiration date. To renew, you must submit updated information for your fleet, including any additions or deletions, changes in weight, and your actual mileage per jurisdiction for the prior year.
Accuracy is critical during the renewal process. Reporting incorrect mileage or failing to update your fleet details can result in penalties or delays. Be sure to renew on time to avoid a lapse in your IRP credentials, which could lead to enforcement actions or the suspension of your operating authority.
IRP Trip Permits in Montana
If you don’t regularly operate interstate and don’t wish to register under IRP, you can apply for a temporary permit istead. This permit allows legal interstate operation for a limited time, typically 72 hours, and is intended for occasional or one-time trips outside Montana.
Trip permits are available directly from the Montana Motor Carrier Services office and through authorized permit services. They are a quick, cost-effective solution for carriers who do not operate across state lines frequently enough to justify full IRP registration.
