INTERNATIONAL REGISTRATION PLAN - APPORTIONED LICENSE PLATES

In the International Registration Plan, a motor carrier purchases a single, apportioned license plate in their base state. The plate is honored by all states and Canadian provinces. IRP fees are distributed based on the number of miles traveled in each state or province.

When do I need apportioned plates (IRP)?

You are required to have apportioned plates if you operate in two or more jurisdictions and your vehicle(s) meet one or more of the following requirements:

  • the power unit licensing weight is 26,001 lbs., or higher;
  • the power unit has more than two axles regardless of licensed weight;
  • the power unit is used in combination and the said combination is 26,001 lbs. or higher; or
  • the power unit performs commercial intrastate movements in another jurisdiction other than Missouri, regardless of licensed weight.

What forms and supporting documents are required to get an apportioned plate?

  • Motor Carrier Application (See below)
  • Secretary of State Corporation or Fictitious Name papers (if applicable)
  • Title or validated titling receipt
  • Lease agreement, if leased
  • Heavy highway vehicle use tax receipt (IRS-form 2290) for power units being licensed at 55,000 lbs. or higher
  • Missouri county personal property tax receipt or tax waiver for the current tax year
  • Actual miles traveled in each jurisdiction, during current reporting period, with an apportioned plate regardless of the base jurisdiction.
