IRP Maryland

The International Registration Plan (IRP) is a cooperative agreement among U.S. states, the District of Columbia, and Canadian provinces that allows commercial vehicles operating across jurisdictions to pay registration fees based on the distance traveled in each area. Maryland officially joined the IRP on March 31, 1987, becoming the 37th jurisdiction to participate. The Maryland Motor Vehicle Administration (MDOT MVA), through its Motor Carrier Services (MCS) Office, manages the IRP program in the state.

If you're a commercial driver, owner-operator, or fleet manager based in Maryland and your operations involve interstate travel, you are likely required to register under IRP. This guide outlines the eligibility requirements, registration steps, renewal process, and how to simplify it all with expert support.

Who Needs to Register for IRP in Maryland?

Maryland law requires you to register under IRP if your vehicle travels outside the state and meets one of the following conditions. Your vehicle is a power unit with two axles and a gross vehicle weight (GVW) over 26,000 pounds, or it has three or more axles regardless of weight, or it is used in combination with another unit and the total combined weight exceeds 26,000 pounds. IRP registration is mandatory if the vehicle is used for transporting property or passengers for hire across state or provincial lines.

If your vehicle has two axles and a GVW of 26,000 pounds or less, you may still apply for IRP registration at your discretion if you intend to operate interstate. However, IRP is not required if your vehicle operates only within Maryland, falls below the weight and axle thresholds, or if you use temporary trip permits for limited out-of-state travel.

How to Register for IRP in Maryland

To register a vehicle under IRP in Maryland, you must open an account through the Maryland Motor Carrier Services Office. The registration process begins with setting up your IRP account and gathering the necessary documentation. After that, you must schedule an appointment with MDOT MVA, which can be done through their online scheduling system. Once your documents are submitted and the application is reviewed, you will pay apportioned registration fees. These fees are calculated based on the jurisdictions where your vehicle will operate and the mileage traveled in each.

After approval, you will receive an apportioned license plate and a cab card, which, under the Full Reciprocity Plan, includes all member jurisdictions, eliminating the need for future trip permits. If you have any questions, you can contact the IRP department at [email protected]. Be sure to include your IRP account number, full name, and phone number if you already have an account.

Documents Required for IRP in Maryland

When applying for IRP in Maryland, the following documents are required:

• Maryland business address verification, such as a utility bill or lease agreement
• Vehicle title or lease agreement in the registrant’s name
• USDOT number and Federal Employer Identification Number (FEIN)
• Proof of Heavy Vehicle Use Tax (IRS Form 2290) for vehicles over 55,000 pounds
• Mileage records or distance reports from the previous reporting year
• A valid Maryland driver’s license or government-issued ID
• Proof of insurance and safety compliance, as required under PRISM regulations

IRP Renewal in Maryland

IRP registration in Maryland must be renewed annually. MDOT MVA typically sends a renewal notice in advance, but it is the registrant’s responsibility to submit the renewal application and payment before the expiration date. To renew, you must update your mileage records for each jurisdiction, verify or update your business information, submit any updated vehicle ownership documents, and ensure your safety record is in compliance with PRISM requirements. You must also pay the applicable renewal fees.

Maryland participates in the federal PRISM program, which ties a carrier’s safety record to registration eligibility. If your safety status is not in compliance, your IRP renewal may be delayed, denied, or lead to suspension of apportioned plates.

Maryland Tax Credit for Class “F” Vehicles

Owners of Class “F” tractors registered in Maryland may apply for an income tax credit certificate through MDOT MVA in the year the vehicle is registered. The tax credit is $400 per vehicle, limited to $10,000 total per taxpayer, which equates to a maximum of 25 vehicles. This credit is non-transferable between tax years and was available for tax years 2017 through 2019. Only 1,250 certificates were issued per year, on a first-come, first-served basis. 

New Requirements for Charter Buses

Recent amendments to the IRP have removed the exemption for buses used to transport chartered parties. Previously, registration under IRP was optional for charter buses. Now, any bus traveling outside of Maryland must either register under IRP or obtain a 72-hour interstate trip permit.
