Missouri IRP Information
What is IRP for trucking? The IRP, meaning International Registration Plan, was established to simplify the process of collecting and distributing registration fees among jurisdictions. If Missouri is your base state, you will register with that IRP office, and they take care of the rest. You will only need one IRP apportioned plate that allows you to travel across any state lines. IRP fees are determined by the number of miles accrued in each jurisdiction and the type of vehicle you operate.
Missouri IRP Registration
If you operate a qualifying motor vehicle in two or more jurisdictions, you are required to have an apportioned plate. But, before you submit an IRP registration, you may be required to obtain a MoDOT Hazardous Waste Transporter license.
When you are ready to apply for the IRP Missouri apportioned plate, you must provide the following documents:
- Motor Carrier Application
- Vehicle title or validated titling receipt
- Lease agreement if the vehicle is leased
- Personal property tax receipt for the current year
- Heavy Highway Vehicle Use Tax form 2290 (power units licensed at 55,000 pounds or more.
You are also required to show that you operate a qualifying vehicle. Under the IRP, a qualifying vehicle is one that is designed, maintained, and used for transporting persons or property. Specific weight requirements are outlined along with more information about vehicle qualifications and other forms needed at the Missouri Department of Transportation, modot.org.
You may apply for a Missouri IRP plate by mail, fax, email, or in person. Addresses and phone numbers are available at the above MoDOT link.
After your application is approved, you will receive one IRP apportioned plate and cab card for each vehicle in your fleet. These items must be appropriately displayed and remain with the vehicle at all times.
Renewing Your Missouri IRP Plate
IRP Missouri plates are valid for one year only. The annual Missouri IRP renewal schedule looks like this:
| Registration Period | File by: | Pay by: | Plate Expires: |
| Jan 1 – Dec 31 | Oct 1 | Dec 1 | Dec 31 |

A penalty of $100 for late renewal filing. Late payment of fees results in a fine of $30 per power unit, up to $150 maximum. It’s also important to remember that you must be compliant with all IFTA quarterly tax payments before applying for the IRP renewal.
