MCS-150
When is my MCS-150 due?
By the DOT Compliance Partner team · January 19, 2026 · 3 min read
The MCS-150 is the form that keeps your carrier information current with FMCSA — fleet size, driver count, operation type, and contact details.
How the schedule works
Updates are generally required on a recurring cycle tied to your USDOT number, whether or not anything about your business has changed. The exact timing depends on your specific registration.
Why it matters
Missing an update can result in your registration being marked inactive, which can affect your ability to operate. It's one of the easiest compliance items to lose track of because there's no single calendar date that applies to everyone.
