Running an interstate trucking business out of Arizona comes with a steady stack of paperwork. If your rigs cross state lines, the Unified Carrier Registration (UCR) is one annual task you can't push to the side.
Here is a straightforward breakdown of how UCR works, what you'll pay, and how to file without hitting any snags.
File UCR OnlineFinished your UCR? Don't forget to file your annual IRS Form 2290 and secure your stamped Schedule 1 for all heavy vehicles before hitting the road.
Unified Carrier Registration (UCR) is a mandatory federal program that requires commercial motor carriers operating across state lines to pay an annual fee based on their fleet size. Created by Congress under the UCR Act of 2005, the revenues collected go directly toward funding state highway safety programs and roadside enforcement efforts.
Even though UCR rules apply to drivers in every state, Arizona is officially a non-participating state. Arizona doesn't collect UCR money directly, but if your trucks cross state boundaries, you are still legally required to register and pay your UCR fees through a designated base state like Utah, California, or Idaho.
Arizona-based motor carriers must register for UCR if they operate commercial vehicles interstate or hold active interstate authority through the FMCSA.
You need to file an annual UCR if you run any of the following across state lines:
Note: If your trucks stay 100% inside Arizona borders and never touch interstate cargo or hazmat, you don't need to file UCR.
Your UCR fee depends entirely on how many power units (trucks and tractors) you run in interstate commerce.
Freight brokers and leasing businesses with no power units pay the baseline rate. Here is the current fee breakdown:
| Fleet Size (Power Units) | UCR Fee |
|---|---|
| 0 – 2 vehicles (Brokers, Forwarders, Owner-Operators) | $46.00 |
| 3 – 5 vehicles | $138.00 |
| 6 – 20 vehicles | $276.00 |
| 21 – 100 vehicles | $963.00 |
| 101 – 1,000 vehicles | $4,592.00 |
| 1,001+ vehicles | $44,836.00 |
Since Arizona doesn't handle UCR filings directly, you'll complete your registration through the official national portal, which assigns your base state.
Follow these steps to get your filing done:
Registration opens every year on October 1, and your payment must be completed by December 31. Law enforcement nationwide starts checking for updated UCR registrations on January 1.
Skipping your UCR filing will lead to trouble at weigh stations and roadside inspections. Officers in participating states can place your trucks out of service on the spot, and fines usually range from $100 to over $1,000 per violation depending on where you get pulled over.
No. UCR is a flat federal safety registration fee tied to fleet size. IFTA tracks state fuel taxes based on mileage, while IRP covers your apportioned license plates and registration. You need to keep up with all three to stay fully legal on the road.
The assistance provided was beyond expectations. This was my first time doing it, and their support stayed with me until everything was completed. It took me longer because I was multitasking and they waited whileI was getting other things done. Thank you! The best service I have ever received from any phone support.

I've been with them for just under a year. They are good people who conduct business in a professional manner. they stay on top of trending news in the trucking industry and use that knowledge to better serve their customers. I like the family atmosphere and the first-name basis. pricing for services is lower than the industry standard , I think I'll stay right here.

I have been using Simple Truck Tax for six years now to file our yearly 2290. It is simple to use, and they file it quickly. I have a login, and it is easy to add and remove trucks. They remember my information, so I don't have to upload it again the following year. I definitely recommend their 2290 service.
