UCR base state: which state you actually file under
Last updated September 18, 2026 · written from the live UCR.gov registration dashboard
Your UCR base state is the state of your principal place of business — where the company is actually run from. Nine states do not participate in the programme (AZ, FL, HI, MD, NV, NJ, OR, VT, WY), and being based in one of them does not exempt you: you designate a participating state instead, usually the nearest one. Either way the fee schedule is identical, from $55 for 0–2 power units up. You do not have to guess which state the portal thinks you are in — UCR.gov displays your base state on the registration-history dashboard, before you start the year's registration.
Base state is the part of UCR people most often get anxious about and least often need to. It decides which state administers your registration. It does not decide what you pay, it does not decide whether you owe the registration, and it is not something you have to work out from first principles in the middle of filing — the portal already holds an answer and shows it to you. What follows is the rule, the nine-state complication, and where exactly on UCR.gov to look.
The rule: principal place of business
Your base state is the state where your business has its principal place of business. That is a deliberately practical test rather than a legal-formalities one, and it points at where the company is genuinely operated from — the office the officers work out of, where the business records live, where dispatch and management actually happen.
Three things it is commonly confused with, and is not:
- • Not your state of incorporation. A Delaware LLC run entirely out of Ohio is based in Ohio.
- • Not where the trucks sleep. Equipment parked across a state line at a customer's yard does not move the base state.
- • Not where you drive. Running loads into thirty states creates no obligation in any of them — one registration covers the lot.
For the overwhelming majority of carriers this is a five-second question with an obvious answer: the state on the letterhead, the state on the MCS-150, the state where the business has always been. It becomes worth thinking about only when a business has genuinely moved, or when it is run from one state and yarded in another.
The nine states that do not participate
41 states participate in UCR. Nine do not — and the word "participate" is doing something specific here that trips up a great many carriers.
"My state does not do UCR, so I do not need it" is understandable and wrong. Non-participating means the state itself does not collect UCR revenue or administer the programme inside its own borders. It does not mean the carriers based there fall outside the programme. If you operate in interstate commerce, the registration applies to you regardless of which of the fifty states you are based in.
What changes, if you are based in one of the nine, is one thing only: you designate a participating state to administer the registration instead of your own. Conventionally that is the nearest participating state in your region — Georgia for a Florida carrier, Pennsylvania or New York for a New Jersey one — and because every state charges the identical national fee, there is no advantage to be had by choosing one over another. More on the nine states.
UCR.gov already shows you your base state
Here is the part almost nobody writes about, because the portal is a JavaScript shell behind a security check and no search engine has ever read it. You do not have to arrive at UCR.gov with a base state decided in your head and hope it matches. The portal displays the one it holds for your USDOT.
It appears on the third screen — the registration-history dashboard, the one that lists every registration year with its status and where you press REGISTER NOW on the 2027 row. The left panel of that screen shows your base state, pulled from your FMCSA record, right alongside the "Last Updated" date of your MCS-150. Both are there before you start the year's registration, which makes that screen the natural checkpoint for both facts.
- • Base state — the state your registration is administered through. Read it; do not assume it.
- • MCS-150 "Last Updated" — how fresh the record is that will autofill your vehicle count two screens later.
- • Every registration year with its status — including any year showing as unregistered, each with its own REGISTER NOW button.
If the state shown is one you can justify as your principal place of business — or, for a carrier in one of the nine, a sensible participating designation — you are done thinking about base state and can press on. If it is a state you left three years ago, the federal record behind it is what needs updating, and that is worth doing properly rather than working around. See where that screen sits in the nine.
The fee is national — the 2027 brackets, everywhere
This table is the same in all fifty states. A carrier based in Texas, a carrier based in Vermont designating a participating state, and a carrier based in Ohio all read the same row for the same power-unit count and pay the same amount. Base state changes where the registration is administered and nothing else.
| Power units | 2027 government feeyou pay this on UCR.gov | EasyUCR service feeoptional, paid to us |

Government fee amounts are set by federal rulemaking and are adjusted between registration years — confirm the current amounts on UCR.gov before you pay. The portal adds its own convenience fee on card and ACH payments.
The 2027 dates, in every state
The calendar is national too. Base state does not shift any of these.
| Registration opens | October 1, 2026 |
| Register for 2027 by | December 31, 2026 |
| 2027 registration year enforced from | January 1, 2027 |

UCR base state — common questions
What is my UCR base state?+
The state where your business has its principal place of business — in practice, where the company is actually run from: the office the officers work out of, where the records are kept, where the operation is directed. It is not necessarily where the trucks are parked, where you are incorporated, or where you happen to live. One base state covers the whole registration; there is no per-state step and no second filing for any other state you drive through.
Which state do I file UCR in if I run in several states?+
The one you are based in, not the ones you drive through. UCR is a single national registration, administered by one state for the carrier based there, and running into forty states does not create forty obligations. You register once, under your base state, and that registration is recognised everywhere the programme is enforced.
My state does not participate in UCR. Am I exempt?+
No, and this is the most expensive misreading in the programme. Arizona, Florida, Hawaii, Maryland, Nevada, New Jersey, Oregon, Vermont, Wyoming do not participate — meaning those states do not collect or enforce UCR themselves. It does not mean carriers based there are outside the programme. If you operate in interstate commerce from one of those nine states, you register by designating a participating base state instead, and you pay the same national fee as everybody else.
Which participating state should I designate?+
Generally the participating state nearest to your principal place of business, within the same region. A Florida carrier commonly designates Georgia; a New Jersey carrier commonly designates Pennsylvania or New York. The point of the rule is that the registration is administered somewhere sensible relative to where you actually operate from, not that you go shopping for a state — the fee is identical everywhere, so there is nothing to shop for.
Does the base state change how much UCR costs?+
No. The fee schedule is national and identical in every state: $55 for 0–2 power units up to $54,165 for the largest fleets in 2027. No state adds a surcharge, no state offers a discount, and a carrier based in a non-participating state pays exactly what a carrier based in a participating one pays. Your base state decides where the money is administered, never how much of it there is.
Where does UCR.gov show my base state?+
On the registration-history dashboard — the screen where you press REGISTER NOW on the year's row. The left panel of that screen shows the base state it holds for your USDOT, alongside the "Last Updated" date of your MCS-150. That makes the base state something you read rather than something you guess: if what is displayed is not a state you can justify, that is the moment to slow down, before you start the year's registration.
What if the base state shown is wrong?+
It usually means the underlying federal record is out of date rather than the portal being mistaken — the base state is derived from your carrier record, so a business that has moved its principal place of business and never updated its MCS-150 will keep showing the old state. Fixing the record is the durable answer, because UCR reads from it every year. If your operation has genuinely relocated, that is the update that ought to happen anyway.
Do I have to file UCR in every state I drive through?+
No. One registration, made under one base state, is recognised across the programme. That is the whole design of UCR — it replaced a patchwork of separate state registrations with a single annual filing, which is why there is no per-state screen anywhere in the nine screens on UCR.gov.
