MCS-150 vs Form 2290: FMCSA vs IRS Filings

By Korey Sharp-Paar · Reviewed by the Fast Trucking Compliance team

Quick answer

MCS-150 is a biennial FMCSA census filing under 49 CFR §390.19T with no fee but mandatory deactivation if missed. Form 2290 is an annual IRS Heavy Vehicle Use Tax under 26 USC §4481 with up to $550 tax per truck and a stamped Schedule 1 receipt required to renew IRP plates. The MCS-150 cycle runs every 24 months from the last-filed date - not the calendar year - and missing it carries penalties up to $1,584 per day under 49 CFR Part 386 Appendix B. Form 2290 covers the federal tax period July 1 through June 30, with returns due August 31 for vehicles in service July 1 under 26 CFR §41.6071(a)-1. E-filing is mandatory for fleets of 25+ trucks per IRS Publication 2290. Carriers must also keep the stamped Schedule 1 in the cab for IRP plate renewal in every base state.

MCS-150 and Form 2290 are both "annual-ish" federal filings every motor carrier eventually encounters, but they live at completely different agencies. MCS-150 is the FMCSA's biennial census - an information return, no money exchanges hands. Form 2290 is an IRS tax form with actual tax due to the federal government for trucks at or above 55,000 lbs gross weight.

When to choose each

When to choose MCS-150

Every USDOT holder

Required regardless of weight, fleet size, or operating territory. Set a reminder 30 days before your due date. Use the MCS-150 deadline calculator to compute your specific window.

When to choose Form 2290

Owners of trucks 55,000 lbs gross or higher

Tax period runs July 1 through June 30. Most fleets file by August 31 to avoid penalty. Owner-operators with one truck typically file directly through an IRS-approved e-file provider; larger fleets are required to e-file. The stamped Schedule 1 is required to renew IRP plates in nearly every state.

Frequently asked questions

Do I need to file MCS-150 if I have not crossed a state line?

Yes if you hold a USDOT. Most state DOTs require a USDOT for in-state CDL operations as well, and that USDOT triggers the MCS-150 obligation regardless of whether you actually run interstate.

Is the 2290 deadline always August 31?

For trucks first used in July of the tax period, yes. For trucks first used after July, the return is due by the last day of the month following first use.

My truck is under 55,000 lbs. Do I owe Form 2290?

No. The HVUT only applies to vehicles with a taxable gross weight of 55,000 pounds or higher. Lighter trucks are exempt from the IRS tax but still owe MCS-150 if they have a USDOT.

Can I file both online?

Yes. MCS-150 is filed at portal.fmcsa.dot.gov. Form 2290 must be e-filed through an IRS-approved provider for fleets of 25+ vehicles, and is recommended for all filers.

My IRP renewal was rejected - what happened?

Most likely cause is a missing or expired Form 2290 stamped Schedule 1. Re-file or update your 2290, then resubmit IRP. The same Schedule 1 covers all trucks listed on the return.
