When is my MCS-150 due?
Enter your USDOT number to find your biennial-update deadline instantly. Miss it and FMCSA deactivates your USDOT number.
How your due date is set
Your MCS-150 schedule is keyed to your USDOT number: the last digit picks the month, and the next-to-last digit picks the year (odd → odd years, even → even). It's due every 24 months — and within 30 days of any major change.
What happens if you miss it
FMCSA deactivates your USDOT number — which means you can't legally operate — plus civil penalties of up to $1,000/day, capped at $10,000. It's one of the easiest deadlines to miss and the most expensive to ignore.
How 1Kompliance helps
We compute every recurring FMCSA deadline from your USDOT number and trucks — MCS-150, IFTA, Form 2290, UCR, your drug & alcohol program — and remind you well before each one. No spreadsheets.
Never track a trucking deadline by hand again
1Kompliance watches every FMCSA deadline for you and reminds you before each one.
