Is UCR the same as IRP or IFTA?

No. UCR is a state safety-enforcement fee paid annually based on fleet size. IRP is the multi-state apportioned plate program. IFTA is the multi-state fuel-tax program. All three are separate filings with separate fees, deadlines, and purposes.

UCR funds state-level enforcement of FMCSA rules. The annual fee is keyed to fleet size and goes into the participating states' enforcement budget. UCR is per-fleet (one fee per carrier, not per truck).

IRP is the apportioned-plate program: carriers running interstate get one plate that's apportioned across all the states where the truck accumulates miles. IRP fees scale with mileage and the truck's registered weight. IRP is per-vehicle and renewed annually.

IFTA is the fuel-tax compact. Carriers report quarterly mileage by state and pay (or receive credit on) the fuel-tax differential between the state where fuel was purchased and the states where miles were driven. IFTA is per-fleet but reported per-state.

Most interstate carriers handle all four (UCR + IRP + IFTA + Form 2290 HVUT) plus state-specific permits like NY HUT or KYU. The deadlines are staggered — UCR Dec 31, IRP varies by state, IFTA quarterly, 2290 Aug 31 — so a permit-management calendar is essential.
