How do I file my UCR registration each year?

Chapter 01

Is this UCR renewal letter real?

UCR itself is real. It is a yearly registration and fee set up by federal law, and the money goes to the 41 States that take part (FMCSA’s 2026 fee rule). But not every letter about it comes from the UCR Plan, the body that runs it. Private companies send some of them. The companies charge more than the official fee and make the letters look official. The official place to register and pay is ucr.gov. So do not pay from a letter. First work out what you really owe, then pay it on the official site.

Here is how that looks in real life. Say you run three trucks out of Illinois under your own authority. You also keep a pickup for parts runs. On Tuesday, October 6, 2026, a letter comes. At the top it says “2027 UCR Annual Renewal, Final Notice”. It has an eagle, your company name and your USDOT number. It tells you to pay $289 by October 31 “to avoid penalties”. A QR code leads to a website with “ucr” in its name, and the address ends in .com. We made this letter up. But the Federal Trade Commission has gone after sales calls, emails and texts built the same way, as you will see below.

First, what is UCR? The law behind it is the Unified Carrier Registration Act of 2005 (the UCR law). Before it, States could charge interstate carriers their own registration fees. Now you register once a year with one State, called your base State, and the money is shared among the States that take part. Each of those States must spend at least that much on truck safety programs, enforcement or running UCR. A board of State officials, people from the trucking industry and one FMCSA official runs the program. Together they are called the UCR Plan. FMCSA writes the fees into the federal rules, on the board’s advice.

Owners often search “is UCR registration legit”. The fee is legit, and you must pay it. The real question is who is asking for the money. The UCR Plan does contact carriers. Its system sends a new carrier a notice to register (the UCR Handbook). It also emails carriers who signed up for automatic renewal on the official site (the UCR Plan’s home page). So a notice is not fake just because it came to you. What matters is where it asks you to pay, and how much.

Private filing services are allowed. The UCR Handbook is the rule book the UCR board adopted in 2024. It says a carrier “may engage a third party” to register and pay for it (the UCR Handbook). It also says the UCR program “does not regulate the fees a private party may charge”. So a service can legally charge you extra for a job the Handbook itself calls “relatively simple”. Some services use a tool the UCR Plan built for filing companies. Those services must post this line on their website: “This website is not affiliated with the Unified Carrier Registration Plan” (the UCR Plan’s agreement with filing services). The same notice ends: “You may register directly with the UCR Plan at www.ucr.gov.”

Some go much further. In 2016 the Federal Trade Commission took a group of filing companies to court (the FTC’s 2016 announcement). The FTC said they used “official-sounding names, official-looking websites” and “warnings of $1,000 in civil penalties or fines”. It said their total price hid a service fee of $25 to $550 or more. It also said many owners were signed up for a yearly renewal they never agreed to. The companies settled in 2018. They were banned from claiming a link to any government office. They must now say they are a private service and show their fees (the FTC’s 2018 announcement). The FTC takes reports of this kind at ReportFraud.ftc.gov.

Now look at your letter again. The site it sends you to does not end in .gov. The real sites, ucr.gov for paying and plan.ucr.gov for information, both do. The letter says October 31, but the real deadline is before January 1 (the UCR Plan’s fee page). And the $289 means nothing until you know your official fee. So you put the letter aside and ask the next question: do you even have to register?

Chapter 02

Does my company have to register for UCR?

Yes, if your company works in interstate commerce. That covers carriers that haul other people’s freight for pay, private carriers that haul their own goods, and exempt carriers such as many farm haulers. It also covers brokers, freight forwarders and companies that lease trucks without drivers to carriers. Carriers from Canada and Mexico that run in the U.S. are covered too. A carrier that only hauls inside its own State does not register (the UCR Plan’s enforcement guidance).

You haul across State lines every week, so you are in. For many owners the answer is less clear, and the UCR Handbook settles most cases (the UCR Handbook).

Interstate means more than crossing a State line. A truck that never leaves Illinois is still in interstate commerce if it hauls a container to or from a port. The same goes for freight that started in another State or will end in one. The Handbook uses port drayage and farm produce hauled to a railhead as examples. So “I never leave my State” does not always mean “I do not need UCR”.

Your USDOT record matters too. The Handbook says you are covered once your USDOT profile shows interstate commerce, or once you hold an active MC number. That is true even before your first load, and even with no trucks at all. A carrier with no trucks still registers in the lowest bracket. For a new company, the step that starts the new entrant safety audit also makes the first UCR fee due. The UCR system then sends a notice. Our guide to the new entrant safety audit covers that first year.

Your base State is usually the State of your main office. Yours is Illinois. Nine States and Washington, D.C. do not take part in UCR (the UCR Plan’s FAQ). They are Arizona, Florida, Hawaii, Maryland, Nevada, New Jersey, Oregon, Vermont and Wyoming. A company based there still registers. It picks a base State by the Handbook’s rules. Say a Florida company has no office in a State that takes part. It may choose from a list of nearby States: Alabama, Arkansas, Georgia, Kentucky, Louisiana, Mississippi, North Carolina, Oklahoma, South Carolina, Tennessee or Texas.

A few more cases. A seasonal carrier that runs interstate for only part of the year still registers. The fee is the same for a full year or part of one, and there is no refund for months you did not run. There is no trip permit for UCR either (the UCR Handbook). And the law lets a State bring its own intrastate carriers into UCR (the UCR law). We did not find a list of States that do this. So if you truly haul only inside your State, ask your State before you skip it.

Chapter 03

Which trucks count, and what are the UCR fees?

Count your power units that weigh over 10,000 pounds, alone or with a trailer. Count the ones registered to your company and the ones you run under a long lease. Trailers never count on their own. That number puts you in one of six brackets. For the 2027 year, 3 to 5 trucks cost $167. For 2026 the same bracket cost $138 (the UCR Plan’s fee table, FMCSA’s 2026 fee rule). Brokers and companies that only lease out trucks pay the smallest fee.

Start with what counts as a truck for UCR. The UCR Handbook says it must be a power unit used on the road for business (the UCR Handbook). It must weigh, or be rated for, more than 10,000 pounds, alone or with its trailer. A smaller vehicle counts if it hauls hazardous materials that need placards, or if it is built to carry more than 10 people with the driver. Trailers stopped counting in 2010.

Your three tractors count. Your trailers do not. Your pickup is under 10,000 pounds by itself, so it does not count. The Handbook adds one catch. If that pickup pulls a trailer, and the pickup, trailer and load together weigh over 10,000 pounds on an interstate trip, the pickup counts. Yours only runs parts in town, so it stays out.

Trucks you do not own can count too. The rule is “owned or operated”. A truck counts for you if it is registered in your company’s name, or if you run it under what the Handbook calls a “long-term lease”. Say an owner-operator runs under your authority on a lease for a year. That truck counts in your fleet. A truck you take on a trip lease, or a short rental, does not.

Next, the law gives you two ways to count (the UCR law). You can use the number of trucks on your latest MCS-150. Or you can use the trucks you owned or ran in the 12 months that ended on June 30 before the UCR year. For the 2027 year, that is the 12 months ending June 30, 2026. The MCS-150, or Motor Carrier Identification Report, is your company report to FMCSA. You update it every two years, at no charge, on FMCSA’s own site (the FTC’s 2018 announcement). It is not UCR. UCR is a separate yearly fee, and it can simply borrow the truck count from your MCS-150.

You have had all three trucks since 2024, and your MCS-150 says three. So both ways give you three. But say your third truck only arrived in August 2026. Then your MCS-150, updated when it came, says three, while the June count says two. The law lets you pick either. The June count would put you one bracket lower: $55 instead of $167 for 2027. The Handbook asks you to keep records that back up your count. It also says States look closely at carriers that pay a lower bracket than their MCS-150 shows. And the UCR Plan compares the number of apportioned plates each carrier holds with the bracket it paid (the UCR Handbook). Apportioned plates are the IRP plates for trucks that run in more than one State. If you cannot back up your count, you pay the difference. So pick the count you can prove.

One more choice: you may leave out trucks that work only inside your State (the UCR law). The UCR Plan’s form for this sets three conditions for the whole year (the UCR Plan’s forms page). The truck never leaves the State. It never hauls freight that comes from or goes to another State. And it has no apportioned plate. You keep a list of those trucks and give it to your base State if asked.

Now find your bracket. These are the fees FMCSA set for each UCR year (FMCSA’s 2026 fee rule). The UCR Plan’s own table shows the same numbers (the UCR Plan’s fee table). From October 1, 2026, the 2027 fees also appear in the federal fee rules.

Brokers, freight forwarders without trucks and leasing companies pay the fee in the first row: $46 for 2026 and $55 for 2027. The fee does not depend on how far or where you run. A carrier that stays in two States pays the same as one that runs in all of them (the UCR Plan’s FAQ). If you add trucks during the year, you do not file again. The new count waits for next year.

Your three trucks put you in the 3 to 5 bracket. For 2027 you owe $167. The letter asked for $289. The extra $122 would have gone to whoever sent it. We made up the $289. The $167 is the official fee.

Now say you also book loads for other carriers under a broker authority. If the brokerage is the same company, you register once. You pay the higher of the two fees, which here is the carrier fee of $167 (the UCR Handbook). If you set up the brokerage as a separate company, such as its own LLC, that company registers too and pays the smallest fee, $55 for 2027. The same goes for a second USDOT number: each number registers and pays for the trucks run under it.

Chapter 04

How do I file and prove I paid?

Go to ucr.gov, the UCR Plan’s national registration site, and register for the year. You fill in a short form with your company details, your USDOT number and your truck count. Then you sign it and pay. Registration for 2027 opens on October 1, 2026, and you must finish before January 1, 2027 (the UCR Plan’s fee page). When you pay, the site gives you a receipt. That receipt, and the record officers see online, are your proof. There is no decal or cab card.

On Tuesday, October 13, you sit down with your USDOT number and your truck list. The UCR Handbook describes the form as one page: your name, address, USDOT number and the facts that determine your fee, mainly your truck count (the UCR Handbook). You pick the count from your MCS-150, which is three. The owner, or another person allowed to sign for the company, signs it. Sign with care. The Handbook says your base State can punish a false form as perjury, the same as lying under oath.

Then you pay $167. You can pay online, or send a check by mail. With a check, the registration does not count until the payment arrives and is posted. So a check mailed on December 29 can leave you unregistered on January 1. If you get stuck, the UCR Plan’s help line is 1-833-827-7526 (the UCR Plan’s fee page). We could not see the payment screens ourselves, because the site does not open for our tools. So we cannot tell you whether a card payment carries a small processing charge.

The official site also offers automatic renewal. The UCR Plan says those renewals use the number of power units on your latest MCS-150 and charge the card you saved (the UCR Plan’s home page). That saves time. But it means a wrong MCS-150 puts you in the wrong bracket, so check that number each fall.

What if a filing service had already paid for you, and now you pay again? The UCR Plan takes refund requests only through the official site, and only for a short time (the UCR Plan’s refund procedure). For the newest UCR year you have 60 days after the payment. For an older year that is still open, you have 30 days. A refund can take about 4 to 6 weeks. So check your record before you pay, not after.

Now the proof. You get no decal, no sticker and no cab card for UCR. The UCR Plan’s answer on this is short: “You are not required to carry any proof of compliance in the vehicle” (the UCR Plan’s FAQ). The Handbook adds that no State may cite you for not showing a UCR paper (the UCR Handbook). Many owners still keep a copy of the receipt in each truck. You save yours as a file and print one copy for the office.

Officers check UCR online. They can look you up on FMCSA’s SAFER site under its UCR tab, or at ucr.gov/enforcement (the UCR Plan’s enforcement flyer). You can look yourself up the same way, so you see what they see. If an officer finds no UCR, the UCR Plan tells officers to write it on the inspection report. It shows there as “392.2 UCR – Failure to pay UCR fees” (the UCR Plan’s enforcement guidance).

Say that happens to one of your drivers in March, even though you paid in October. Your receipt is your proof that the report is wrong. You can ask for an incorrectly recorded violation to be corrected through FMCSA’s DataQs system, and our guide on how to dispute a violation in DataQs walks through it. Keep the truck list and lease papers behind your count too. UCR audits are mostly done from a desk, with records and phone calls, and your papers are how you answer them.

Chapter 05

What if I missed a year of UCR?

Pay it now. The fee for a missed year does not go away. Each UCR year stays open for late registration until December 31 of the next year (FMCSA’s 2026 fee rule). Until you pay, a State can fine you. Each State sets its own penalties, and some States hold back truck plates until UCR is paid (the UCR Handbook). Paying late does not cancel a ticket you already got, so do not wait for one.

Back to your story. While you look yourself up on SAFER, you see a problem. There is no UCR for 2026. Last fall was busy, you meant to do it, and it slipped. Your trucks have run all of 2026 without it.

How much trouble is that? The UCR Plan’s fee page is plain about it. After January 1, “the registration fee is still due, but a non-registrant may then be subjected to state enforcement action” (the UCR Plan’s fee page). For the 2026 year, the UCR Plan asked States to start checking at the roadside on January 1, 2026. It also asked them to hold two special weeks of checks, January 11 to 17 and June 7 to 13, 2026 (the UCR Plan’s enforcement guidance). The law lets States issue tickets and “reasonable fines” for not paying (the UCR law). The UCR Plan’s flyer for officers says “Noncompliance penalties are set by each state” (the UCR Plan’s enforcement flyer). The Handbook says many of them are “significant”. We found no single federal UCR fine, and no official list of each State’s amounts.

The consequences go beyond roadside fines. The Handbook says some States refuse to renew a carrier’s apportioned plates until UCR is done (the UCR Handbook). A carrier found to have paid too little is treated as not registered, and that shows on FMCSA’s public site. So in some States a missed year can stop your plate renewal, not just result in a ticket.

So you pay 2026 the same day, on the same site. The 2026 year is still open for payment on the official site (the UCR Plan’s home page). For 2026, your count comes from your MCS-150 or from the 12 months that ended on June 30, 2025. You had three trucks then too, so you owe the 2026 fee for 3 to 5 trucks: $138 (the UCR Plan’s fee table). With the $167 for 2027, you have paid $305 for two years, and you have two receipts in your company’s name.

Check the year before that too. Under the same rule, the 2025 year stays open until December 31, 2026 (FMCSA’s 2026 fee rule). If you missed 2025 as well, pay it before this year ends. A ticket you got while unregistered is handled by the State that wrote it, under its own rules. Your new receipt shows that you have paid since.

Chapter 06

What has changed, and when should I do it?

The fees went up for the 2027 year. FMCSA published the new fees on September 1, 2026, and they take effect on October 1, 2026. They are about 20 percent higher on average: $9 more for the smallest carriers and brokers, and $29 more for 3 to 5 trucks (FMCSA’s 2026 fee rule). The 2026 fees were the same as 2025. So any letter, website or old guide that quotes $46 or $138 for 2027 is out of date.

Why the rise? The rule says the UCR Plan had been collecting less than planned. The 2027 fees are meant to bring in $21.79 million more, to reach the $118 million the law requires for the States and for running UCR. The rule also notes that, even after this rise, the 2027 fees are lower than the fees of 2019 to 2022. The new fees stay in place until a later rule changes them.

You may hear that UCR is being fought in court. FMCSA’s rule mentions a case that challenges UCR itself, and a separate request to stop the new fees. A federal appeals court turned that request down on June 17, 2026, and FMCSA went ahead. The rule also says neither FMCSA nor the UCR board has “the discretion to cease collecting fees”. We did not check where the case stands now. Until a court or Congress changes the law, plan to pay.

When should you do it? Any day from October 1 to December 31, 2026, the fee is the same. Paying early gives you time to fix a wrong count, catch a missed year and wait out a mailed check. Put it in the same yearly routine as your other filings. Your IFTA fuel tax returns come every quarter, as our guide to preparing and filing an IFTA return explains. Your IFTA license and decals have their own renewal, covered in our guide to the IFTA license and decals.

Some things we could not check. We found no official list of each State’s UCR penalties. We found the UCR Plan’s roadside start dates for the 2025 and 2026 years, but none yet for 2027. We could not open the payment screens of ucr.gov with our tools. FMCSA also keeps a page on misleading marketing to new carriers. Its site blocks our tools, so we could not read it, but it should open in your browser. And we did not check the current state of the court case.

Here is the whole job in one place. Throw out the letter, or report it. Count your power units. Pick the count you can prove. Pay $167 for 2027 on ucr.gov, and pay any open year you missed. Save the receipts and your truck list. Then look yourself up once, the way an officer would.

If you want someone to track UCR, IFTA and your other yearly filings for you, and keep the proof in one place, here is what we offer.
