File your MCS-150 biennial update online. Filed the same business day.

The MCS-150 due month is set by the last digit of your USDOT number (1=Jan, 2=Feb … 0=Oct). Even next-to-last digits file in even years; odd next-to-last digits file in odd years. Enter your USDOT above and we calculate the exact deadline automatically.

Every interstate motor carrier, freight broker and freight forwarder with an active USDOT number must file the MCS-150 every 24 months, regardless of fleet size; intrastate hazmat-permit carriers file the MCS-150B, and intrastate-only carriers follow their state's rule.

$175 for a single filing or $400 once for lifetime updates, plus $25 only if you need Login.gov setup help.

Every 24 months. The last digit of your USDOT number sets the month (1 = January … 0 = October), and the next-to-last digit sets the year: even digits file in even years, odd digits in odd years.

A missed biennial update can lead to civil penalties and deactivation of the USDOT number (49 CFR 390.19T(b)(4)). Note: FMCSA has temporarily suspended enforcement of biennial updates and USDOT inactivation for updates due on or after June 1, 2026, until further notice. A carrier with a deactivated USDOT number can't operate until the update is filed. FMCSA controls when the update shows in its records.

FMCSA no longer uses a USDOT PIN. Since Motus opened on May 19, 2026 (legacy systems were retired May 14), you sign in with Login.gov and link your USDOT number to your account. If you need help setting that up, FastMCS150 charges $25 only if you need Login.gov setup help.

MCS-150 filing requires USDOT number, FEIN or SSN, business address, operation type (interstate/intrastate), miles traveled last calendar year, fleet breakdown (straight trucks, tractors, trailers), hazmat status, and driver counts within/beyond 100-mile radius.

Yes. FastMCS150Filing.com lets you start online in under 5 minutes, and your MCS-150 is prepared and submitted to FMCSA for you. You can also file it yourself for free in FMCSA's Motus system at motus.dot.gov.

An MCS-150 filing is the Motor Carrier Identification Report - the federal form interstate USDOT holders submit every two years (49 CFR Part 390) to keep their carrier registration current. It updates FMCSA on fleet size, mileage, business address, hazmat status, and driver counts. A missed biennial update can lead to civil penalties and deactivation of the USDOT number (49 CFR 390.19T(b)(4)). Note: FMCSA has temporarily suspended enforcement of biennial updates and USDOT inactivation for updates due on or after June 1, 2026, until further notice.

MCS-150 must be filed every two years (biennially) in the month matching the last digit of your USDOT number. Out-of-cycle filings are also required within 30 days of any address change, fleet expansion, or operational change. Carriers with USDOT ending in 1 file in January, ending in 2 file in February, etc.

Yes. You can file your MCS-150 online directly with FMCSA in its Motus registration system at motus.dot.gov, signing in with Login.gov and linking your USDOT number to your account, or have it prepared and submitted for you by a third-party filing service like FastMCS150Filing. The FMCSA charges no fee for the filing itself; the entire cost is the third-party preparation and submission service if used. FastMCS150 is $175 per biennial update or $400 once for lifetime updates covering every future biennial filing the company will ever owe - a one-time payment that bundles every upcoming due month for the life of the USDOT number. FMCSA no longer uses a USDOT PIN. Since Motus opened on May 19, 2026 (legacy systems were retired May 14), you sign in with Login.gov and link your USDOT number to your account. Many carriers hire a service to avoid setting that up themselves; FastMCS150 charges $25 only if you need Login.gov setup help.

You update your MCS-150 by submitting a new Motor Carrier Identification Report to the FMCSA - online in FMCSA's Motus registration system at motus.dot.gov (sign in with Login.gov), or through a third-party filing service that prepares and submits it for you. Updates are required every 24 months on the biennial cycle (due in the month matching the last digit of your USDOT number: 1=January, 2=February, … 9=September, 0=October), and out-of-cycle within 30 days of any change to legal name, business address, fleet size, operation type, mileage estimates, hazmat status, or driver counts under 49 CFR Part 390. A missed biennial update can lead to civil penalties and deactivation of the USDOT number (49 CFR 390.19T(b)(4)). Note: FMCSA has temporarily suspended enforcement of biennial updates and USDOT inactivation for updates due on or after June 1, 2026, until further notice. Even-next-to-last-digit USDOTs file in even years; odd in odd.

MCS-150 is the standard Motor Carrier Identification Report filed by every registered motor carrier, freight broker, and freight forwarder biennially under 49 CFR Part 390 to keep the FMCSA carrier record current. MCS-150B is the Combined Motor Carrier Identification Report and Hazardous Materials Permit Application - filed by carriers transporting hazardous materials in quantities that require an FMCSA Hazardous Materials Safety Permit (HMSP) under 49 CFR Part 385 Subpart E. The MCS-150B includes everything on the MCS-150 plus 11 additional pages capturing HMSP-specific data: HM commodity types, package counts, bulk vs non-bulk handling, cargo tank specifications, and emergency response plans. Most non-hazmat carriers file the standard MCS-150; only carriers holding (or applying for) an FMCSA Hazardous Materials Safety Permit file MCS-150B. A third variant, MCS-150C for intermodal-equipment providers, follows the same biennial cycle.

The simplest MCS-150 path is to have your USDOT number and company details ready before you start. With FastMCS150 it takes under 5 minutes of your time, and your MCS-150 is prepared and submitted to FMCSA for you. The DIY route in Motus at motus.dot.gov is free if your Login.gov account is already linked to your USDOT number. FMCSA controls when the update shows in its records.

Three checks separate trusted MCS-150 services from upsell shops: the price is flat and disclosed up front, the service states plainly that the FMCSA itself charges nothing (you can always file free in Motus at motus.dot.gov), and the guarantee terms are written down. FastMCS150 meets all three - $175 for a biennial update or $400 once for lifetime updates, with the free-DIY option stated on this page. Re-filing guarantee: if a filing is rejected because of an error on our side, it's refiled free. No hidden fees.
