## Who Administers IRP in Michigan?

IRP in Michigan runs through the Department of State, the Secretary of State's office that handles all vehicle registration: carriers that run qualified vehicles into other states or provinces register there for an apportioned plate and cab card. They pay a fee split by where the fleet drives, and the Department of Treasury handles IFTA separately. Michigan IRP account holders log in through the Department of State's e-Services with a MiLogin account to apply, renew or replace a plate online. Geography makes a Detroit or Grand Rapids carrier interjurisdictional almost by default. Ohio and Indiana are an hour south, and the Windsor-Detroit gateway is the busiest commercial land crossing between Canada and the US, with the Blue Water Bridge at Port Huron another major truck crossing, which puts Ontario on most Michigan fleets' distance schedules.

## What Drives the Michigan Apportioned Fee?

Ontario is the line that sets a Michigan IRP application apart. Automotive and parts freight runs Windsor to Detroit and Sarnia to Port Huron every day, and a cross-border fleet's July-to-June distance can put a large share of its miles in Ontario, reported in miles even though the province measures in kilometres. Add Ohio, Indiana and Illinois for the Midwest runs and the schedule has half a dozen entries that move the fee. Telematics reports each unit's distance by jurisdiction for the year from continuously logged position, and the same report run quarterly gives you the numbers for the Treasury's IFTA return.

*An apportioned fee is each jurisdiction's full-year fee weighted by the share of distance run there, added up and paid once to the base jurisdiction.*

## Roadside Checks and Audits

The Michigan State Police Commercial Vehicle Enforcement Division checks cab cards and weights at the weigh stations on I-94, I-75 and I-96, and Ontario's MTO checks the same truck on the other side of the bridge. If one device handles your IRP distance, IFTA and an ELD registered with FMCSA in the US and certified by an accredited body in Canada, you carry one consistent record through both inspections.

## FAQ

### Who handles IRP registration in Michigan?

The Michigan Department of State's IRP unit handles IRP registration. Applications, renewals and supplements for the apportioned plate and cab card all go through that office. IFTA is a separate program in Michigan, handled by the Department of Treasury, so a carrier that needs both credentials deals with two agencies even though the same distance records feed both filings.

### If our Michigan trucks stay local, do we still register under IRP?

No. IRP exists to split one registration fee among the jurisdictions a vehicle operates in, and a Michigan truck that never leaves the state has nothing to split. It stays on an ordinary Michigan Department of State plate. Once it starts scheduled runs to Ohio, it needs the apportioned plate, or a trip permit for a single trip.

### What distance does the Michigan IRP renewal use?

The Michigan IRP renewal uses actual miles in each jurisdiction, per vehicle, for the twelve months ending June 30 before the registration year. You report them to the Michigan Department of State's IRP unit. A fleet in its first year has no history, so it uses the average per-vehicle distance chart published by IRP, Inc. until it has a full year of actual distance.

### Do IRP and IFTA cover the same thing for a Michigan carrier?

No, they cover different money. IRP splits one year's registration fee among the jurisdictions the truck runs in, and you pay it through the Michigan Department of State's IRP unit. IFTA reconciles the fuel tax owed to each of those jurisdictions every quarter. One set of distance records feeds both, but each one is its own filing.

### How long should a Michigan carrier keep IRP distance records?

Keep Michigan IRP distance records long enough to cover the audit window, which runs three years after the registration year closes. A carrier that keeps its GPS distance reports for that whole period can answer an audit from the Michigan Department of State's IRP unit in an afternoon, without rebuilding mileage from fuel receipts and driver memory.
