TxDMV has a program for licensing commercial vehicles engaged in interstate operations. Apportioned registration, also known as the International Registration Plan (IRP), lets you obtain registration credentials in one jurisdiction, giving you the freedom of interstate travel without the inconvenience and expense of purchasing trip permits.
If you operate interstate, you may qualify for apportioned registration. To learn if you qualify, contact your local TxDMV Regional Service Center or send us an email at
How to Apply
All apportioned accounts are maintained in our online system, TxIRP. If this is your first time to obtain Apportioned registration on your vehicles, please visit your local TxDMV Regional Service Center to set-up your registration account.
Once your account is set-up, you may make changes to and renew your registration using one of the following methods:
- Visit one of the TxDMV Regional Service Centers, or
- Mail renewal and/or supplemental applications to Texas Department of Motor Vehicles, Motor Carrier Division – IRP Renewal, P.O. Box 26440, Austin, TX 78755-0440.
Fees and Payment Information
Registration fees are calculated based on distance percentages for each jurisdiction in which your vehicle or fleet operates.
Fees are payable by personal check, business check, cashier's check or money order in person, or online via electronic check (ACH).
If the gross vehicle weight of your vehicle is 55,000 pounds or more, Federal law requires that proof of payment of the Federal Heavy Vehicle Use Tax (HVUT) be provided at time of vehicle registration.
As an apportioned carrier, you are required to maintain detailed operational records in order to renew your apportioned registration each year. Base jurisdictions are required to examine an average of 3% of the number of renewed fleets each year to ensure compliance with the IRP and to guarantee that the proper revenues are being collected for each jurisdiction. As a result, every motor carrier registered with the TxIRP will be subject to a compliance examination of their operational records.
Apportioned tow trucks must also maintain registration through the Texas Department of Licensing and Regulation (TDLR).
