Biennial Update (MCS-150) Filing
Running a motor carrier business involves more than just hauling freight. There are critical regulations to follow, including timely MCS-150 filings with the Federal Motor Carrier Safety Administration (FMCSA).
Motor carriers are required to file an MCS-150 update, also known as a Biennial Update, every 24 months or risk deactivation of their USDOT number.
At first glance, the MCS-150 update may seem straightforward—confirming your fleet’s details, mileage, and contact information. However, for many carriers, it can feel like navigating a complex maze.
Failure to file an accurate and timely MCS-150 update can result in USDOT number deactivation and fines up to $10,000. Ensuring compliance is essential to keeping your operations running smoothly.

MCS-150 Filing Requirements: FAQs
What is an MCS-150 Update / Biennial Update?
This is a required biennial filing that keeps the FMCSA informed about your operation. You confirm core details, such as your vehicle count and mileage. It seems minor, but skipping this update can lead to deactivation of your USDOT number.
What do I need before filing?
Have your USDOT number, login credentials or a PIN, and basic information like fleet size and driver count. Accurate data speeds up the process and prevents errors.
When should I file my MCS-150 update?
You must file the Biennial Update of the form MCS-150 every 24 months. The last digit of your USDOT Number determines the due month (1 = January, 2 = February, …, 0 = October). The next-to-last digit determines the year—file in even-numbered years if it is even and in odd-numbered years if it is odd. However, if you have a big change—like a new address or expanded fleet—you must file an immediate edit rather than waiting for your biennial date.
What happens if I miss a filing?
Your USDOT number can be deactivated, halting your operations immediately. Fines can reach $10,000, which is painful for any business, large or small. Staying on top of filing deadlines is the safest way to avoid penalties.
Can I file online?
Absolutely. Online filing provides real-time confirmations and reduces the chance of data-entry mistakes. DOT Compliance Support can guide you through this digital process, ensuring everything is completed properly.
How often do I renew my MCS-150?
A renewal is required every two years. If something major changes in your operations—like a new headquarters location or a surge in vehicle count—you need to file an update right away. Waiting can lead to inaccuracies that jeopardize your compliance.
Who needs a Biennial MCS-150 update?
Any motor carrier operating under FMCSA rules must keep an active USDOT number. Even if your business is on pause, you still need to stay compliant. Neglecting this responsibility can mean starting from scratch when you are ready to return to the road.
