Twenty Percent More to Register: FMCSA Finalizes the 2027 UCR Fee Hike — $9 for a One-Truck Carrier, $9,329 for the Biggest Fleets

The annual fee nobody notices until it is due is going up. On September 1 FMCSA published the final rule raising Unified Carrier Registration fees by an average of 20 percent for the 2027 registration year and every year after, until the next adjustment. The rule takes effect October 1, 2026 — the same day the 2027 registration window opens — so the first invoices at the new rate arrive within the month. For a one-truck operation the difference is nine dollars. For a fleet of more than a thousand power units it is $9,329.

The new table, bracket by bracket

UCR fees are set by fleet size — power units only, trailers do not count — in six brackets that Congress capped at six. The 2027 schedule, against the 2025 fees that were carried over unchanged into 2026:

FMCSA's own framing of the small-carrier impact: the increase works out to roughly $9.41 per vehicle for a carrier at the bottom of any bracket, and the per-truck cost of registering in 2027 lands between $54.11 and $55.67 across all six brackets. The agency certified the rule as having no significant impact on small businesses because the increase is under one percent of their revenue.

Why: the states are owed $118 million and the cushion is gone

UCR is not a federal revenue line. The money is collected by the UCR Plan and passed to the 41 participating states, which by law must spend at least that amount on motor carrier safety programs and enforcement. Each state's entitlement is fixed in statute; what actually comes in depends on how many carriers register and how big their fleets are. When collections fall short, the law requires fees to go up in later years to recover the gap; when they run over, the surplus sits in the depository and fees must come down. That mechanism is why fees fell in 2023 and 2024 — and why they are rising now. FMCSA says the excess collections from past years have been depleted, the plan has been taking in less than projected, and the 2027 increase is expected to cover a projected $21.79 million shortfall against a total statutory requirement of $118 million.

Thirty-one against, two for, and the answer was no

The proposal went out April 7 with a 30-day comment window, which FMCSA stretched to May 26 after the Small Business in Transportation Coalition asked for time to inspect the board's supporting documents. Thirty-four comments came in, 33 within scope. Most were owner-operators and small carriers citing fuel, insurance and maintenance costs. OOIDA argued the system no longer serves its original purpose and "merely generates 'slush fund revenue' for States," which can use it as a non-federal match for federal safety grants, and that the bracket structure hits single-truck operators harder per vehicle than large fleets. SBTC went further: it has a petition before the U.S. Court of Appeals for the D.C. Circuit seeking to halt the rulemaking, and asked FMCSA to withdraw the rule until that case is resolved. The National Propane Gas Association objected to a $250,000 legal-defense allocation being baked into the increase.

FMCSA's responses were short. Congress created the fee and neither the agency nor the board can stop collecting it. The states' entitlements are fixed by statute, so the only variable is the fee. The board's recommendation, issued September 18, 2025, is "within a reasonable range." On the per-vehicle complaint, the agency pointed out that any bracket system means a carrier at the bottom of a bracket pays more per truck than one at the top, and the statute allows no more than six brackets. And on the fear of an automatic 20 percent every year: the rule authorizes a single increase for 2027; the schedule then stays put until a new rulemaking, with the board due to recommend or decline an adjustment before October 1, 2028.

“ Once again, the UCR Board has failed to properly justify how they determined the proposed 20% fee increase for 2027. As the U.S. Department of Transportation continues to review wasteful spending programs, UCR is a prime candidate for review. ”

What actually changes for you

Who must register does not change: interstate motor carriers, private carriers, brokers, freight forwarders and leasing companies, whether or not they are based in one of the nine non-participating states — Arizona, Florida, Hawaii, Maryland, Nevada, New Jersey, Oregon, Vermont, Wyoming — or the District of Columbia, because those jurisdictions simply do not collect; the obligation follows the carrier. The bracket you land in still depends on the vehicles you own or operate, so a fleet sitting at 21 or 101 units is paying the full weight of the next bracket for one truck. And the window for 2027 opens October 1 with the new numbers already in place; there is no early-registration discount at the old rate.
