Who must register for UCR in 2027 (and who does not)
Unified Carrier Registration reaches five kinds of businesses that touch interstate commerce. If your company is one of them, the 2027 fee is owed before January 1, 2027 - even if you run a single truck.
The five categories UCR covers
The fee rule for registration year 2027 lists who is in scope. All five register and pay; the amount depends on entity type and fleet size.
For-hire motor carriers
Companies that haul freight or passengers for compensation in interstate commerce - from owner-operators to large fleets. Bracket fee by vehicles owned and/or operated.
Private exempt motor carriers
Private carriers transporting hazardous materials or passengers are covered even though they are not for-hire. Same bracket schedule.
Freight forwarders
Entities that arrange interstate transportation and assume responsibility for the cargo pay the carrier bracket fee for their fleet size.
Brokers
Interstate freight brokers register and pay the flat B1 fee - $55 for 2027 - regardless of how many vehicles are involved.
Leasing companies
Companies that lease vehicles with drivers to interstate operators pay the same flat $55 as brokers for 2027.
Small operations count
The 0-2 vehicle bracket exists because one- and two-truck operations are covered too: $55 for 2027, up from $46 in 2026.
It comes down to interstate commerce
UCR registration turns on whether your commercial motor vehicle operation crosses state lines or moves goods that have crossed them. A carrier that only runs inside one state, with no interstate moves, generally falls outside UCR. The moment your trucks work in interstate commerce - hauling freight between states, or moving interstate cargo on the final leg - registration applies.
Private carriers should not assume they are invisible to UCR. Private operations that transport hazardous materials or passengers are named in the fee rule alongside for-hire carriers. And private carriers of general freight in interstate commerce should verify their status directly: the official "Do I need to Register?" tool at plan.ucr.gov is built for exactly that question, and the UCR Plan help line is 1-833-827-7526.
Not covered? Operators working purely intrastate - no interstate moves, no interstate cargo - are outside the UCR scope described in the fee rule. If any part of your operation touches interstate commerce, register before January 1, 2027.
Who-registers FAQ
I have one truck. Do I still owe UCR?
Yes, if you operate in interstate commerce. You fall in the 0-2 vehicle bracket: $55 for 2027, up from $46 in 2026.
My company is private, not for-hire. Am I exempt?
Not automatically. Private exempt motor carriers - those transporting hazardous materials or passengers - are covered by UCR. Other private carriers of interstate freight should check their status with the official tool at plan.ucr.gov.
Do brokers with no trucks pay anything?
Yes. Brokers and leasing companies pay the flat B1 fee - $55 for 2027 - whether or not they own vehicles.
What if I only crossed state lines once this year?
Interstate commerce is what counts, not how often you cross. If your operation worked in interstate commerce, registration applies and the fee is due before January 1, 2027.
