A common misconception: only carriers with trucks owe UCR. In fact, every entity holding interstate FMCSA operating authority owes Unified Carrier Registration 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. For dedicated guidance on the broker product line, see our UCR for brokers landing page.
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 without drivers to interstate motor carriers are also subject to UCR — but their fee does not scale with fleet size. Under 49 USC §14504a(f)(1)(A)(ii), the fee charged to a broker or leasing company equals the smallest fee charged to a motor carrier. A leasing company with 40 units in its interstate lease-out pool still files at the lowest bracket. The vehicles it leases out are counted by the carriers that control them under long-term leases, per §14504a(f)(2).
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 leasing companies pay the smallest bracket fee by statute; forwarders file at Tier 1 unless they operate their own vehicles, in which case the fleet count controls.
