International Registration Plan

The International Registration Plan (IRP) is a registration reciprocity agreement among the states of the U.S. and provinces of Canada, providing the payment of license fees on the basis of total distance operated in all jurisdictions. Each carrier is required to pay registration fees for the state or provinces where they will travel and conduct business. IRP allows the carrier to submit a single application to a single base state for all jurisdictions for which the carrier operates.
Without IRP, a carrier would have to submit multiple registration applications; one for each jurisdiction in which they travel. Colorado offers multiyear registrations for the commercial trailers that are Tax Class A vehicles registered in IRP

IRP/International Fuel Tax Agreement (IFTA) Registration Process

The Department of Revenue's Taxation Division and Division of Motor Vehicles have improved the procedure to allow carriers who need IRP registration and IFTA credentials to be served during a single transaction at the DMV office located at 1881 Pierce Street, Lakewood, Colorado.

FAQ’s on the Full Reciprocity Plan for IRP
What is the Full Reciprocity Plan (FRP) for IRP?

The FRP will change the IRP to make the Plan more efficient, more equitable and more flexible by granting full reciprocity for all apportioned vehicles in all IRP Member Jurisdictions and removing from the Plan any provisions related to 1st and 2nd year estimated distance for established fleets.

What is the effective date of the FRP?

January 1, 2015.

If a registrant’s renewal date is April 1, 2015, at what point will they come under full reciprocity?

Any registrant whose registration year begins on or after January 1, 2015, would be subject to the FRP provisions. For the example of an April 1, 2015 renewal, they would be registered under full reciprocity beginning with their April 1, 2015 renewal.

Are all existing IRP carriers going to be subject to the average per vehicle distance chart calculations for all member jurisdictions the first year under full reciprocity? 

No, existing carriers renewing their fleets for registrant year beginning on or after January 1, 2015, will report actual distance accumulated during the distance reporting period.

When should fees be based on the jurisdictional average per vehicle distance chart?

When a registrant’s fleet is considered new under Section 420 of the Plan, or the fleet did not accumulate any actual distance during the distance reporting period, fees will be calculated using the base jurisdiction’s average per vehicle distance chart

When is actual distance to be used?

Under FRP, actual distance must be used when the registrant’s fleet accumulated any actual distance during the distance reporting period.

For a new fleet can a combination of actual and average per vehicle distance be used?

No, a new fleet has no actual distance. Under FRP, the jurisdiction’s average per vehicle distance chart must be used to determine fees for all IRP jurisdictions. A combination of actual distance and average per vehicle distance should never be used under FRP.

What does a carrier pay when all of the actual miles occurred in Colorado? Does the carrier pay 100% of Colorado Fees?

Yes, under FRP the registrant must report the actual distance accumulated during the distance reporting period and pay the appropriate fees. The official commentary under the apportionable vehicle definition allows a customer 18 months to travel in at least two jurisdictions.

Under FRP what weight should be displayed on the IRP cab card?

Under FRP, the gross vehicle weight should be displayed on the cab card for every IRP jurisdiction. The base declared gross weight plus the comparable weight for each member jurisdiction should be reflected.

How are weights over 80,000 pounds to be handled?

The FRP doesn’t affect how weights over 80,000 pounds are handled. The registrant should continue to declare the gross vehicle weight.
