> UCR is annual fee registration. IRP is apportioned plates. IFTA is fuel tax reporting. Three separate programs every interstate carrier must file — here’s the side-by-side under 49 USC §14504a.

## TL;DR

> UCR is annual fee registration. IRP is apportioned plates. IFTA is fuel-tax reporting. Three separate programs under three different statutes — holding any one does not satisfy the other two.

## Key takeaways

- UCR = annual flat fee under 49 USC §14504a, tiered by fleet size, one filing per legal entity.
- IRP = apportioned plates, fees mileage-driven across member jurisdictions, governed by interstate compact.
- IFTA = fuel-tax reconciliation across 48 U.S. states + 10 Canadian provinces, quarterly returns.
- A current apportioned plate or IFTA decal does not satisfy UCR — and vice versa.
- Order of operations for a new interstate carrier: USDOT, MC, BOC-3, UCR, IRP, IFTA.

## FAQ

### Is UCR the same as IRP?

No. UCR (49 USC §14504a, 49 CFR Part 367) is an annual fee-based registration funding state enforcement of motor-carrier safety rules. IRP (International Registration Plan) is apportioned vehicle registration — the license plates and cab cards — administered through your base jurisdiction. Both apply to most interstate carriers, but they are separate filings with separate fees.

### Is IFTA the same as UCR?

No. IFTA (International Fuel Tax Agreement) is a fuel-tax reporting program where carriers file quarterly returns and pay tax based on miles operated and fuel consumed in member jurisdictions. UCR is a flat annual registration fee. Different agencies, different filing cadences, different rules.

### If I file IRP and IFTA, is my UCR covered?

No. Each program is independent. A carrier can be fully current on IRP plates and IFTA fuel tax and still be out of compliance with UCR. The three are sometimes filed through the same state Department of Transportation portal, which adds to the confusion, but they are distinct obligations under different statutes.

### Which one comes first when I get authority?

Practically: USDOT and MC authority first, then UCR (annual), then IRP plates (annual, but renewals are staggered by carrier), then IFTA (annual decals plus quarterly returns). UCR doesn’t require IRP or IFTA to file — you can have UCR without plates yet — but you can’t legally roll without all three once you’re operating in interstate commerce.
