Annual renewal. The exact due month is set by your base state and varies (staggered registration). Administered by Base jurisdiction (state DMV/DOT). Here is who it applies to, when it falls, and what a late filing actually costs.
Carriers operating apportioned (interstate) vehicles registered under the International Registration Plan.
Not federally deterministic — the renewal month is assigned by your base jurisdiction. The tool stores your renewal month once you enter it, then reminds you annually — sent by us, by hand, during early access.
We do not calculate this one, and we will not pretend to. There is no federal formula behind it: only your base jurisdiction knows your month. Ask them once, and the reminder is yours from then on.
Expired apportioned plates = citations, fines, and out-of-service risk at roadside / scales.
The International Registration Plan is a reciprocity agreement among the 48 contiguous states, the District of Columbia and 10 Canadian provinces. You register your fleet once, in your base jurisdiction, instead of registering separately in every state you touch. It typically applies to commercial vehicles over 26,000 lbs combined gross weight running in two or more jurisdictions.
Apportioned means what it says: fees are calculated from the percentage of distance you travelled in each jurisdiction, at each jurisdiction's own rates. Two identical trucks with identical plates can owe very different totals because their miles fell differently. Your base jurisdiction issues the apportioned plate and the cab card that carries the result.
The distance data has to come from somewhere, and that somewhere is your own records. IRP expects records reflecting all activity of every apportioned vehicle — loaded, empty, bobtail and deadhead alike — plus distance and fuel records, the drivers' source documents, and the monthly, quarterly and annual summaries by vehicle and by fleet. A renewal month that arrives before the summaries are done is the expensive version.
We are a reminder tool, not the agency. The rule itself is published by the Base jurisdiction (state DMV/DOT), and that page is the one that wins if anything here ever falls out of date:
Enter your USDOT number once and see your next MCS-150 deadline free — then keep the rest of the calendar in one place.
