UCR Frequently Asked Questions

UCR is a federally-mandated program that requires individuals and companies operating commercial motor vehicles in interstate or international commerce to register and pay an annual fee. It was established under the Unified Carrier Registration Act of 2005. The fees are collected by participating states and help fund motor carrier safety programs and enforcement.

For UCR, a commercial motor vehicle generally is one that has a gross vehicle weight or combined weight rating of 10,001 pounds or more, is designed to transport more than 10 passengers (including the driver), or is used to transport placarded hazardous materials. Only power units (trucks/tractors) count toward your fee bracket.

No — they're separate. UCR is its own annual registration and fee. IRP (apportioned plates) and IFTA (fuel tax) are different programs, and Form 2290 is the federal Heavy Vehicle Use Tax paid to the IRS. Paying one does not cover the others; you may need to handle each separately.

You generally must register if you operate commercial motor vehicles in interstate commerce (crossing state lines or in international commerce). This includes for-hire and private motor carriers, as well as brokers, freight forwarders, and leasing companies. If you only operate within a single state (intrastate), you typically do not need UCR.

Carriers that operate only within one state (purely intrastate) are generally exempt. Certain vehicles are also outside UCR, such as those with a gross vehicle weight rating under 10,001 pounds (unless hauling placarded hazardous materials or designed to carry more than 10 passengers). If you never cross state lines and your operation is purely intrastate, you likely don't need to file.

Yes. Brokers, freight forwarders, and leasing companies that operate in interstate commerce are required to register for UCR. If they don't operate any power units of their own, they pay the lowest fee bracket ($46).

The UCR fee is a flat fee based only on the number of commercial motor vehicles (power units) you operate — not on mileage, revenue, or how far you drive. Vehicle counts fall into six brackets, and everyone in the same bracket pays the same flat fee. Trailers, dollies, intrastate-only vehicles, and vehicles under 10,001 lbs are not counted.

For the 2025 and 2026 registration years the national UCR fees are: 0–2 vehicles = $46; 3–5 = $138; 6–20 = $276; 21–100 = $963; 101–1,000 = $4,592; and 1,001 or more = $44,836. Brokers, freight forwarders, and leasing companies with no power units pay the lowest bracket ($46). These are the government fees; a filing service like TAB Inc adds its own service fee.

No — the UCR fee is never prorated. You pay the full annual fee for the calendar year no matter when you file, whether that's January, June, or December. Even if you receive your operating authority late in the year, the current year's UCR is still due at full price, and it covers that calendar year (not 12 months forward).

No. UCR fees are generally non-refundable once the registration has been submitted and paid, even if you later cancel your operating authority. Make sure your vehicle count is correct before you file. TAB Inc's service fee is likewise non-refundable once we've started processing your filing.

Count the power units (trucks and tractors) you operate in interstate commerce that you own or lease. Do not count trailers, dollies, converter gear, vehicles used only intrastate, or vehicles under 10,001 lbs. For owner-operators, trucks registered under the motor carrier's authority count toward the carrier's fleet; owner-operator-registered trucks count toward the owner-operator's own filing.

UCR is an annual registration tied to the calendar year. Registration for the upcoming year opens around October 1, and you should file by December 31 — enforcement of the new year begins January 1. So a filing done before year-end is for the FOLLOWING year. Missed the deadline, or just got your authority? You can still file for the current year at any time. TAB Inc supports both early (next-year) and late (current-year) filings.

It depends on timing. Before December 31 you're typically filing for the upcoming year (the next year's registration opens around October 1). If you missed the deadline, just started operating, or need coverage right now, you file for the current year. TAB Inc supports both — just pick the registration year that applies to you during checkout.

UCR itself does not add a percentage-based late penalty — if you file late, you simply pay the standard tier fee for that registration year. The real exposure is enforcement. Operating without a valid UCR can lead to: (1) Roadside citations — state police and commercial vehicle inspectors can issue tickets commonly ranging from $100 up to $5,000 depending on the state where you're stopped; (2) Out-of-service / detention — officers can hold your truck at a scale or inspection point until you show active UCR compliance; and (3) State registration holds — some states may block your future IRP or IFTA renewals until past-due UCR periods are cleared.

You can still file — and UCR does not charge an extra late fee for filing after the deadline; you pay the normal tier fee for the registration year. What matters is getting compliant quickly, because until you do you're exposed to enforcement: roadside citations (commonly $100 to $5,000 depending on the state), being placed out of service or detained at an inspection point, and possible holds on your future IRP or IFTA renewals. If you missed it, the best move is to file now to close the gap.

Yes. UCR can be filed at any time during the calendar year, and the registration covers that entire calendar year — not just the remaining months. If you missed a prior year, you can usually file it retroactively at the same fee.

Keep your UCR confirmation and payment records for at least two years from the filing date or due date, whichever is later. Being unable to produce proof of a valid registration can lead to additional penalties.

Your base state is the participating state you register through. It's usually the state where your principal place of business is located. If your state doesn't participate in UCR, you choose the nearest participating state. You pay the same national fee regardless of which base state you use.

Most states participate. The non-participating states are Arizona, Florida, Hawaii, Maryland, Nevada, New Jersey, Oregon, Vermont, Wyoming, and Washington D.C. If your business is based in a non-participating state, you file through the nearest participating state — but your fee is the same national amount.

Filing itself takes only a few minutes. Most registrations are processed the same business day, and government databases typically update within a few hours. With TAB Inc, you complete a short guided flow, pay, and get your confirmation number right away.

UCR does not issue a physical credential (like a cab card or sticker) that you must carry. Registration is verified electronically through the national database. It's still a good idea to keep a copy of your confirmation of registration, and you should retain your records for about two years.

You'll typically need your legal business name, your USDOT number (and MC/docket number if you have one), your EIN, your business address, and the number of qualifying commercial vehicles you operate. TAB Inc walks you through each field and matches your vehicle count to the correct fee bracket automatically.

If you reported the wrong number of vehicles, you can usually file a correction. If your correct count falls in a higher bracket, you pay the difference. It's important to report an accurate count, because an incorrect filing can be treated as non-compliant at inspection.

Using TAB Inc is completely optional. You can register directly with the National Registration System at www.ucr.gov and pay only the government fee. TAB Inc is a private, third-party service that prepares and submits your filing for a service fee, with a guided flow, stored confirmations, and optional auto-renewal. We are not affiliated with any government agency.

Your total is the official UCR government fee plus a TAB Inc service fee, shown clearly before you pay. If you pay by bank account (ACH) there's no card processing fee; paying by credit or debit card adds a small processing fee (2.9% + $0.30). You'll always see the full breakdown before checkout.

Auto-renewal lets TAB Inc file and pay your UCR for the next registration year automatically, before the deadline, using your saved payment method. You can enroll from your account and pause or cancel it anytime. It's the easiest way to never miss a UCR deadline.
