IRP in Illinois: Apportioned Registration, Fees and the Distance Schedule
Illinois carriers that run qualified vehicles into other states or provinces register under IRP with the Illinois Secretary of State's Commercial and Farm Truck Division, and pay an apportioned fee split by where the fleet actually drives. Here's how the credential works in Illinois, what drives the fee, and where the distance figures come from.
Who Administers IRP in Illinois
Illinois administers IRP through the Secretary of State's Commercial and Farm Truck Division, while IFTA is handled by the Department of Revenue through MyTax Illinois — two agencies, two logins. Chicago is the largest rail and truck interchange in North America, and an Illinois-based fleet typically runs both local drayage that never leaves the metro and interstate hauls into Indiana, Wisconsin, Iowa, Missouri and beyond. The interstate half registers with Illinois as its base jurisdiction.
The threshold is the Plan's: a power unit over 26,000 pounds gross or registered weight, or with three or more axles, or in a combination over 26,000 pounds, operating in two or more member jurisdictions. Trailers are not apportioned; they carry an ordinary plate and travel on the power unit's cab card.
What Drives the Illinois Apportioned Fee
The fee is the sum of every jurisdiction's registration fee for the vehicle's weight class, each weighted by the fleet's percentage of distance there over the twelve months ending June 30 before the registration year. Registered weight is the largest lever, and the distance split is the second.
The Illinois schedule for a Chicago fleet is a Midwest map: Indiana and Wisconsin in large percentages because they are minutes from the yards, Iowa, Missouri, Michigan and Ohio for the regional runs, and Ontario for fleets running to Detroit and across. The local trucks that stay in Cook County should not be on the schedule at all, which is a vehicle-group question in the telematics platform. A distance-by-jurisdiction report run on the interstate group, from continuously logged position, produces the July-to-June schedule per unit and the IFTA quarter from one dataset.
Roadside and Audit
Illinois State Police commercial vehicle enforcement operates the weigh stations on I-80, I-55, I-57 and I-94, checking cab cards, weights and ELD records together. A fleet whose IRP, IFTA and ELD come from one telematics record has the shortest stops.
The base jurisdiction can audit the distance behind an application for three years after the registration year closes, and asks for trip-level distance by jurisdiction tied to a unit and a date. GPS trip logs behind a distance report answer that; reconstructed trip sheets get the fee recalculated.
Frequently asked questions
Who handles IRP registration in Illinois?
The Illinois Secretary of State's Commercial and Farm Truck Division. Applications, renewals and supplements for the apportioned plate and cab card go through that office.
Does a Illinois truck that never leaves the jurisdiction need IRP?
No. IRP applies to qualified vehicles operating in two or more member jurisdictions. A vehicle that stays home registers the ordinary way, and an occasional trip can use a trip permit instead.
What distance does the Illinois IRP renewal use?
Actual distance in each jurisdiction for the twelve months ending June 30 before the registration year, per vehicle. A first-year fleet with no history uses the base jurisdiction's average distance chart.
Is IRP the same as IFTA?
No. IRP apportions the annual registration fee; IFTA settles quarterly fuel tax. They share a weight threshold and both need distance by jurisdiction, but they are separate credentials, and in many jurisdictions separate agencies.
How long must IRP distance records be kept?
At least three years after the close of the registration year they support, since that is the audit window.
