Prorate services

Prorate is the process of calculating registration fees and taxes for multiple jurisdictions.


The International Registration Plan (IRP) is a reciprocity agreement between the United States, the District of Columbia and Canada that recognizes the registration of commercial motor vehicles issued by other jurisdictions. Motor carriers register with and pay fees to their jurisdiction.

The prorate fees are based on the percentage of the total distance travelled in each IRP jurisdiction, according to that jurisdiction’s fee schedule. These fees are then distributed to the appropriate jurisdictions.

Registered motor carriers receive a licence plate and cab cards that allow their fleets to travel through all IRP member jurisdictions.
