MCS-150 biennial update for owner-operators
Every active USDOT files an MCS-150 biennial update once every 24 months under 49 CFR §390.19. For a single- truck owner-operator, the filing is short — vehicle counts, mileage, contact info, classification — and we handle the FMCSA submission for $100 flat, same business day, SAFER reflection typically within 24-48 hours.
What the MCS-150 does
The MCS-150 keeps the FMCSA carrier-information database current. Vehicle counts, mileage estimates, and contact info all roll into the carrier's SAFER record — which roadside inspectors, brokers, and shippers pull when verifying carrier identity. A current MCS-150 means your USDOT shows as ACTIVE and your record reflects current operations; an overdue MCS-150 means the USDOT slips into inactive status with the broker/shipper friction that follows.
For owner-operators, the biennial cadence catches changes that would otherwise go undocumented — a truck swap, a change in trailer count, a new contact email after the original was lost in a breakup or job change, an updated principal place of business after a move. See our how-to-file walkthrough and MCS-150 vs MCS-150B comparison if you also haul hazmat.

Owner-operator MCS-150 questions
When does my owner-operator MCS-150 come due?
Every 24 months. The exact month is keyed to your USDOT number — the second-to-last digit sets the month, and the last digit sets odd/even-year cadence. So USDOT 12345 (last digit 5, odd) is due in May (second-to-last digit 4 maps to month 5) of every odd-numbered year. The MCS-150 form has a chart that maps the digit pattern to the due month; FMCSA also sends a reminder email if the carrier has a current contact email on file.
What info goes on the owner-operator MCS-150?
Vehicle counts (truck and trailer separately), annual mileage estimate, principal place of business address, named officer or owner, USDOT contact info (email and phone for FMCSA notifications), classification of operation (private, for-hire, exempt for-hire, contract, etc.), cargo classifications, and driver counts (CDL and non-CDL). For a single-truck owner-operator, most fields are 1 or fixed values — the filing takes 5-10 minutes for an experienced owner-operator.
Can I file MCS-150 myself or do I need a service?
You can file yourself for free at fmcsa.dot.gov. Most owner-operators choose to file directly to save the service fee. The trade-off is monitoring — the FMCSA portal does not give same-day SAFER reflection confirmation, so you have to check back manually for the carrier-status update. Carriers who want SAFER monitoring, FMCSA correspondence forwarding, and a one-screenshot done-deal use a service. The substantive filing is identical either way.
