A common misconception: only carriers with trucks owe UCR. In fact, every entity holding interstate FMCSA operating authority owes UCR annually — including freight brokers, freight forwarders, and leasing companies that operate no vehicles of their own. The program is keyed to authority, not to fleet size.
Why Brokers Owe UCR
Under 49 CFR Part 367, any entity registered with FMCSA for interstate operations must pay UCR. Brokers hold MC-B (property broker) or MC-BH (household-goods broker) operating authority, which is interstate registration by definition. The regulation does not exempt brokers; it places them in the same registration regime as carriers, just at a lower tier.
The Tier-1 Default
UCR tiers are based on the number of commercial motor vehicles the registrant operated in interstate commerce during the prior 12 months. A broker who arranges loads but operates no vehicles has a count of zero, which places them in Tier 1 (0–2 vehicles) — the lowest fee tier. This is true regardless of the broker's revenue, load volume, or bond size. A billion-dollar brokerage with zero trucks and a single-truck owner-operator both file at Tier 1.
Freight Forwarders
Freight forwarders (FF authority) are treated like brokers for UCR purposes, with one nuance: forwarders that do operate their own trucks count those trucks. If a forwarder runs a small interstate fleet for the first-mile or last-mile leg of consolidated loads, those vehicles count toward the tier. Most forwarders are still Tier 1 because they subcontract the long-haul leg; a forwarder that actually operates 10 trucks files at Tier 3.
Leasing Companies
Leasing companies that supply vehicles to interstate motor carriers are also subject to UCR. They count the vehicles they lease out, not the carriers they lease to. A leasing company with 40 units in its interstate lease-out pool files at Tier 4 (21–100 vehicles). This surprises some operators — the count is based on the lessor's fleet, not the lessees.
Dual-Authority Operators
Some entities hold both carrier (MC) and broker (MC-B) authority — the “carrier-broker” dual-authority model. UCR is one filing per entity, not per authority. A carrier-broker with five trucks files a single UCR registration at Tier 2 (3–5 vehicles). The tier is the vehicle count for the entity; the authority types do not multiply the fee.
Enforcement for Brokers
Brokers do not drive trucks, so they rarely face roadside UCR enforcement. Broker UCR enforcement is administrative: FMCSA and the UCR Plan can audit brokers, and a broker found out of compliance can be assessed back fees plus penalties. Some shippers and large carriers also check broker UCR status as part of their carrier qualification process, which turns a missing broker UCR into a lost-booking problem rather than a roadside problem.
Bottom line: If you hold FMCSA interstate authority, you owe UCR — even if you own zero trucks. Brokers and forwarders file at Tier 1 unless they operate their own vehicles. Leasing companies count their lease-out fleet.
