UCR for brokers vs UCR for carriers
Both brokers and motor carriers file UCR annually under 49 USC §14504a, and the federal-state UCR Plan and Agreement applies the same registration framework to both. The fee is tier-based on power-unit count: brokers count zero vehicles (they don't operate equipment under their MC-B authority), so they file at the lowest bracket - $46 for the 2026 registration year. Carriers count their power units (any motor vehicle of 10,001+ lbs GVWR or GVW used in interstate commerce) and file at the appropriate tier from Bracket 1 (0-2 units) up to Bracket 6 (1,001+ units). Same form, different tier math; the underlying registration framework is identical, and both broker and carrier registrations are paid through any of the 41 UCR participating states. Brokers under §13904 with no separate motor-carrier authority always pay the lowest bracket regardless of book of business.

Brokers - always Tier 1
Brokers file UCR at Tier 1 because they own no commercial motor vehicles. The §14504a tier calculation is based on the carrier's power-unit count; a broker arranging transportation between shippers and carriers operates without owning equipment, so the count is zero. Zero falls within the 0-2 vehicle Tier 1 bracket. Every broker pays the Tier 1 fee ($46 in 2026) regardless of business volume - a $5M-revenue freight broker pays the same UCR fee as a $50K-revenue startup broker.
For brokers maintaining the BMC-84 surety bond ($75,000) or BMC-85 trust fund ($75,000) under §387.301, the UCR fee is small relative to the bonding cost. Annual UCR is a $46 line item; the surety bond premium runs $1,000-$2,500 annually depending on the broker's credit profile. Total annual broker compliance cost is dominated by bonding, not UCR.
Motor carriers - tier scales with fleet
Motor carriers file UCR at the tier corresponding to their power-unit count. Tier brackets: Tier 1 (0–2 vehicles, $46), Tier 2 (3–5 vehicles, $138), Tier 3 (6–20 vehicles, $276), Tier 4 (21–100 vehicles, $963), Tier 5 (101–1,000 vehicles, $4,592), Tier 6 (1,001+ vehicles, $44,836). The fee scales sharply between tiers; carriers crossing tier boundaries see substantial fee increases.
For owner-operators with 1-2 trucks, Tier 1 is the typical tier - $46 annually. For small fleets at 3-5 trucks, Tier 2 ($138) applies. The transition from Tier 2 to Tier 3 (at 6+ trucks) doubles the fee. Carriers in growth mode should plan for tier upgrades during fleet expansion budgeting.
Combined entities - broker plus carrier
Some legal entities hold both a motor-carrier MC and a broker MC under the same legal name (typical at mid-size and larger fleets that operate their own equipment plus broker out demand spikes). For UCR purposes, the combined entity files a single UCR registration based on the combined fleet count - the carrier-side power units count, the broker side adds zero. The tier reflects the carrier-side count.
For carriers spinning off brokerage operations into a separate legal entity (common pattern for liability separation), each legal entity files its own UCR. The carrier entity files at the appropriate tier based on its fleet count; the broker entity files at Tier 1. Two separate UCR filings, two separate fees, but operationally simpler than commingling at a single legal entity.
Frequently asked questions
Are brokers always Tier 1?
Yes. Brokers do not operate vehicles, so their fleet count is zero. Zero falls within the 0-2 vehicle Tier 1 bracket. Every broker holding an MC pays the Tier 1 UCR fee ($46 in 2026) regardless of business volume.
What about freight forwarders?
Freight forwarders also typically file at Tier 1 because they don't operate vehicles. Some freight forwarders own equipment for terminal operations; if so, those vehicles count toward the tier calculation.
Can a single legal entity file as both broker and carrier?
A single legal entity can hold both an MC carrier authority and an MC broker authority and operate under both. UCR filings combine into a single carrier-level filing - the fleet count from the carrier authority drives the tier; the broker side adds zero vehicles. The total fleet count is what matters for tier.
