Maryland Income Tax Credit Certificate for Class “F” Vehicle Registration
Owners of Class “F” tractors registered in Maryland may apply for an income tax credit certificate from the Maryland Department of Transportation Motor Vehicle Administration (MDOT MVA) in the year the vehicle was registered. The certificate may be applied to your Maryland state income tax to offset the expense of registering a Class “F” vehicle.
The certificate will be issued in the amount of $400 per vehicle and limited to $10,000 (maximum 25 vehicles) for one taxpayer. The credit may not extend to another taxable year.
Credits will be issued for tax years 2017 through 2019.
NOTE: Certificates will be issued on a first come first serve basis, with a limitation of 1,250 certificates per year.
Maryland participates in the Performance and Registration Information Systems Management (PRISM) program.
State of Maryland participates in the PRISM program. PRISM is a Federal/State partnership used to identify motor carriers with deficient safety records and links a carrier's safety fitness to the ability to register and operate vehicles.
International Registration Plan (IRP) provides a framework for PRISM by facilitating two vital functions. First, it establishes a system of accountability by identifying the carrier responsible for the vehicle’s safety. Second, unsafe carriers are subject to sanctions until their safety performance meets Federal and State standards. Motor carriers that have been prohibited from operating in interstate commerce by the FMCSA may result in a denial or suspended registration by the State. For additional information

New Requirement for Charter Buses
The International Registration Plan (IRP) has been amended to remove the exemption for buses used in the transportation of chartered parties. Currently, registration in the IRP for chartered buses has been optional. Buses traveling outside the state are required to register under the Interstate Registration Plan (IRP) or obtain a 72 hour interstate permit.
IRP Program Adopts Full Reciprocity Plan
