IFTA/IRP Registration Manual

International Registration Plan (IRP)...

Oklahoma is a member of the International Registration Plan (IRP). IRP is an agreement among states and certain Canadian provinces that allows proportional registration of commercial vehicles, with that registration being recognized in all of the jurisdictions. Vehicles are registered on the principle of apportioned registration, which is a means of registering vehicles concurrently for more than one jurisdiction, based on the laden weight and miles traveled within each jurisdiction.

The Motor Vehicle Division has a Prorate Section that deals exclusively with IRP issues. They may be reached at 405/521-3036. In addition, designated motor license agencies (tag agencies) are equipped to process IRP transactions. Those agents are designated in the tag agency listing incorporated within this site.

International Fuel Tax Agreement (IFTA)...

The tax applies to those operating qualified motor vehicles in more than one IFTA jurisdiction. Qualified vehicles are defined as those:

Fuel taxes for Oklahoma and any member jurisdiction are reported and paid on one tax return filed with the Oklahoma Tax Commission. Oklahoma then distributes fuel taxes to the other member states.
