If you own or operate commercial trucks, especially across multiple states or provinces, you’ve likely heard of IRP (International Registration Plan) and IFTA (International Fuel Tax Agreement). Both are essential for legal interstate and interprovincial trucking operations in North America, but they serve different purposes.
This resource page breaks down the differences between IRP and IFTA, helping trucking companies, owner-operators, and fleet managers understand what each program covers, why they matter, and how to comply.

What is an IRP?
The International Registration Plan (IRP) is a vehicle registration reciprocity agreement among U.S. states and Canadian provinces. It allows commercial motor carriers to register their vehicles in their home jurisdiction and receive apportioned license plates that authorize operation in all participating jurisdictions.
- Purpose: Distributes vehicle registration fees based on the proportion of miles traveled in each jurisdiction.
- How it works: Carriers obtain a single “apportioned” license plate and cab card from their base jurisdiction. Fees are then shared among all jurisdictions where the vehicle operates, according to the miles driven in each.
- Who needs IRP: Generally, commercial vehicles over 26,000 pounds gross vehicle weight (GVW) or those with three or more axles,operating in two or more member jurisdictions
What is IFTA?
The International Fuel Tax Agreement (IFTA) is an agreement among U.S. states and Canadian provinces to simplify fuel tax reporting for commercial motor carriers operating in multiple jurisdictions.
- Purpose: Simplifies fuel tax reporting for carriers by consolidating tax payments and filings into a single quarterly report to the base jurisdiction.
- How it works: Carriers track miles traveled and fuel purchased in each jurisdiction. Taxes are calculated based on where the fuel is used, not just where it was purchased. The base jurisdiction collects the taxes and distributes them to the appropriate states or provinces.
- Who needs IFTA: Commercial vehicles over 26,000 pounds GVW or with three or more axles, operating in two or more member jurisdictions
