UCR registration for 2027: fees, deadline, and who has to file

The short version

If you hold interstate authority or run commercial vehicles across state lines, you register once a year at ucr.gov, the UCR Plan's National Registration System. Your fee depends on how many commercial motor vehicles you own, lease long-term, or operate. Brokers and leasing companies that don't run trucks pay the lowest bracket.

FMCSA set the 2027 fees in a final rule published September 1, 2026 (91 FR 56063), effective October 1, 2026. The rule says the increase "averages 20 percent" over the fees used for 2025 and 2026.

You don't have to carry proof in the truck. Officers check your status on SAFER or the UCR system during a stop or inspection, and penalties for not paying are set by each state.

2027 UCR fees by fleet size

Sources: the UCR Plan's fee bracket page and 49 CFR 367.50 as amended by the 2026 rule. The 2026 column is the 2025 fee schedule, which FMCSA's 2024 rule kept in place until a new rule replaced it.

Fees aren't prorated. The UCR Handbook says the fee is the same "for a year or for part of a year," and there are no trip permits. A carrier that gets authority in November 2026 still pays the full 2026 fee if it operated in 2026, and the full 2027 fee for next year.

Who has to register

The UCR Plan's enforcement flyer covers "all motor carriers (for-hire, private and exempt) as well as brokers, freight forwarders and leasing companies operating in interstate or international commerce." Two groups are left out: private passenger carriers and carriers that operate solely intrastate.

That last row is our interpretation. The Handbook doesn't address leased-on owner-operators directly. It does say the rules apply once a business has active motor carrier authority, and that a lessor holding authority but leasing all its trucks to others should pay the lowest bracket. If you're unsure, ask the carrier's safety department whether your truck is on its UCR count, and get the answer in writing.

How to count your vehicles

For the fee, a commercial motor vehicle is a self-propelled vehicle with a gross vehicle weight rating or gross vehicle weight of at least 10,001 pounds, whichever is greater (49 U.S.C. 31101). Trailers don't count. A one-ton pickup rated over 10,000 pounds does, which matters if you run hotshot.

The statute, 49 U.S.C. 14504a(f), gives two ways to count:

1. The number of vehicles on your most recently filed MCS-150, or
2. The number you owned, leased long-term, or operated during the 12 months ending June 30 of the year before the registration year. For 2027, that's July 1, 2025 through June 30, 2026.

The Handbook points out that the two can give different numbers, because the MCS-150 only has to be updated every two years. A few rules apply to either count. A long-term lease means 30 days or more. A vehicle you run under more than one USDOT number gets counted under each one. And you can leave out vehicles used only in intrastate commerce.

If your registration auto-renews, the UCR Plan's October 2026 newsletter says the system uses the power units on your most current MCS-150. Check that number before the renewal goes through. If it's out of date, update the MCS-150 first.

A worked example

This is a hypothetical. A small carrier based in Ohio files its 2027 UCR in November 2026.

The law allows either count, but underpaying has a cost. The Handbook says a registrant that pays less than its bracket requires is "treated as if it has not registered." Whichever count you use, keep the records that back it up: titles, leases, the MCS-150, and the dates trucks came and went. And if the MCS-150 is two trucks behind reality, fix it. You're supposed to keep it current anyway, and our compliance guide explains the biennial schedule.

Where to register and which state you go through

Register at ucr.gov. You pay through your base state, which is normally the state where your principal place of business is, and that one payment covers all participating states.

Ten jurisdictions don't take part in UCR: Arizona, Florida, Hawaii, Maryland, Nevada, New Jersey, Oregon, Vermont, Wyoming, and Washington, D.C. Carriers based there still register. They pick a participating state as a base. The Handbook, for example, lets an Arizona, Hawaii, Nevada, Oregon, or Wyoming carrier choose Alaska, California, Colorado, Idaho, Montana, New Mexico, North Dakota, South Dakota, Utah, or Washington. Florida-based carriers choose from a list of Southern states. Running only in non-participating states doesn't get an interstate carrier out of the fee.

What happens if you don't pay

We didn't find a federal penalty amount for carriers in the UCR statute. The law preserves the states' power to issue citations and fines, and the UCR Plan's enforcement flyer says "noncompliance penalties are set by each state." At an inspection, an unpaid UCR shows up as a 392.2 violation. The Handbook says some states won't issue or renew IRP apportioned plates until UCR is paid. After January 1, the fee is still due and states can enforce.

Enforcement is real. The October 2026 newsletter says one Illinois officer wrote 19 UCR violations in September.

New carriers have one temporary gap. USDOT numbers created in FMCSA's Motus system since May 14, 2026 haven't been reaching SAFER, so the UCR Plan's June 2026 newsletter recommends that states not enforce failure to register against those carriers for now. That's a recommendation to the states, not an exemption. Register anyway.

Put it on the calendar

UCR opens October 1 and has to be paid before January 1, every year. Pay it in the same sitting as your fourth-quarter IFTA prep or MCS-150 check so it doesn't get lost in December. Then keep the confirmation with your permits. The trucking compliance guide has the rest of the annual calendar, and the trucking accounting and IFTA workflow covers where the fee goes in your books.
