The MCS-150 biennial update is a required FMCSA filing for motor carriers and other regulated entities under FMCSA jurisdiction. While the filing may seem routine, missing the deadline can create serious compliance issues for a carrier.
The FMCSA requires regulated entities to update their information every two years, even if nothing has changed.
Why the MCS-150 Filing Matters:
The MCS-150 keeps a carrier’s USDOT record up to date. It confirms or updates the company’s legal name, address, contact information, vehicle count, driver count, cargo classification, operation type, and other core business details.
This information supports federal oversight, safety monitoring, and carrier identification. When the information is outdated, the company’s public record may no longer accurately reflect its operations.
What Happens if You Miss the Deadline?
Failing to file an MCS-150 can result in several consequences.
- USDOT Number Deactivation: Failure to complete the biennial update may result in the deactivation of the USDOT number. A deactivated USDOT number can prevent a carrier from legally operating commercial motor vehicles. For active carriers, this can create immediate business disruption, including stopped operations, delayed loads, lost revenue, and customer service issues.
- Civil Penalties: The FMCSA may impose civil penalties for failure to complete required updates. FMCSA guidance states that failure to complete biennial updates may subject entities to civil penalties of up to $1,000 per day, with a maximum penalty of $10,000. For small fleets and owner-operators, even a short compliance delay can create unnecessary financial exposure.
- Public Record Issues: An outdated or missed filing can affect the accuracy of the company’s USDOT record. Carriers, brokers, shippers, insurers, and other parties may review public registration information when assessing whether a company appears active and compliant. Keeping the MCS-150 current helps maintain a cleaner compliance profile.
- Operational Delays: If a USDOT number is deactivated, the company may need to complete the required filing and wait for the record to be updated before returning to normal operations. This can delay dispatch, onboarding, customer commitments, and other business activities.
Do You Still Need to File if Nothing Changed?
Yes. The FMCSA requires a biennial update every two years, even if the company has not changed its information.
The filing is not only for changes. It is also used to confirm that the information on file is still accurate.
How Do You Know When Your MCS-150 Is Due?
The MCS-150 filing deadline is based on the last two digits of the USDOT number.
The second-to-last digit determines the filing year. An odd number of files in odd-numbered years, and an even number of files in even-numbered years.
The last digit determines the filing month:
USDOT Number Ends In Filing Month
1 January
2 February
3 March
4 April
5 May
6 June
7 July
8 August
9 September
0 October
The update must be filed by the last day of the assigned month.
What Should You Do if You Missed It?
If you missed your MCS-150 deadline, do not ignore the issue. The carrier should review its USDOT record, confirm whether the number is active or deactivated, and complete the required filing as soon as possible.
If any business information has changed, the filing should be updated accurately rather than rushed with outdated information.
