IRP Frequently Asked Questions

The N.C. Division of Motor Vehicles' IRP online renewal service allows individuals to renew their International Registration Plan plates and cab cards online. IRP registrants are required to record mileage for each state traveled and report this mileage for the reporting period required.

Note: Registered motor vehicles that have a taxable gross weight of 55,000 pounds or more must file a Heavy Vehicle Tax (2290) form with the Internal Revenue Service.
