When is my update due?
The schedule
The last digit sets the month: the update is due by the last day of that month. The next-to-last digit sets the year: odd digit, odd-numbered years; even digit, even-numbered years.
| Last digit | Due by |
|---|---|
| 1 | January 31 |
| 2 | February 28/29 |
| 3 | March 31 |
| 4 | April 30 |
| 5 | May 31 |
| 6 | June 30 |
| 7 | July 31 |
| 8 | August 31 |
| 9 | September 30 |
| 0 | October 31 |
Example: USDOT 1234567 ends in 7, so it is due by July 31. The next-to-last digit, 6, is even, so it files in even years: 2026, 2028. You also update within 30 days of any change, such as address, phone, email or number of trucks. An update filed in the 12 months before the due date counts.
Filing in Motus
- Motus replaced the old FMCSA registration portal in May 2026. Go to motus.dot.gov.
- Sign in with Login.gov. Motus requires identity verification with a government-issued ID, so set it up before the due date, not on it.
- The company official claims the company's USDOT record the first time, then reviews and updates the fields: address and contacts, operation type, cargo, power units, drivers and last year's mileage.
- File even if nothing changed. The update is free; sites that charge a fee are private filing services, not FMCSA.
- MC numbers were not eliminated with the move to Motus. Keep using yours.
Missed it? The 2026 pause
Normally a carrier that misses its biennial update can have its USDOT number inactivated. During the Motus rollout, FMCSA has paused enforcement: for updates due on or after June 1, 2026, USDOT numbers are not being inactivated for a missed update. The update is still required, and FMCSA has said it will give notice before enforcement resumes. File as soon as Motus lets you.
Why the truck count matters
Your UCR fee can be based on the number of trucks in your latest MCS-150, and FMCSA uses the same counts for your safety measures. An outdated count can cost money in both places.
We keep the dates, you keep driving
IFTAX tracks your MCS-150, UCR, IFTA and every driver and truck document on one calendar, and reminds you before anything is due.
