PDP For Fleets - 3 Months Free
A recent article in Freightwaves suggested “For companies that have previously considered adding a per-diem plan, but have yet to do so, now is a great time to reconsider your recruiting strategy.[i] While the media is awash with articles covering the ELD mandate and tax reform, everyone has overlooked the impact on tax compliance recordkeeping obligations to substantiate trucker per diem.  Everyone but Per Diem Plus.

A Statutory Conflict - 6 month / 3-year rule

FMCSA Part 395 section 395.8(k)(1) requires motor carriers to retain all supporting documents used by the motor carrier to verify the information recorded on the driver’s record of duty status for a period of 6 months. But,

Internal Revenue Code section 6501(a) establishes the statute of limitations for the IRS to assess taxes on a taxpayer expires three (3) years from the due date of the return or the date on which it was filed, whichever is later.

Fleets and self-employed drivers retain certain records required by FMCSA to comply with DOT regulations, but prudently discard ELD backups after 6 months. However, the IRS only accepts driver logbooks as proof of overnight truck driving trips to substantiate per diem[ii].   Contrary to popular belief trip sheets, mileage logs or settlement statements do not fulfill these statutory requirements. Therefore, fleets adding an accountable per diem program and self-employed drivers face a Catch-22; shield themselves from FMCSA exposure or risk the wrath of IRS auditors. ELD / AOBR backups are straightforward until one considers an e-log for a one driver for a single week can be 20-plus pages or 1,000 pages annually and requires manual reconciliation to establish qualifying overnight truck driving trips. Per Diem Plus was designed to resolve this regulatory Catch-22 by separating FMCSA and IRS retention rules. Per Diem Plus Fleets is the only IRS-compliant mobile application cloud-based solution that replaces logbooks by automating per diem tracking for travel in the USA and Canada. Users can run an itemized “date, place and amount”  report for a week, a month or even a year in less than 30 seconds. Per diem and expenses data and receipts are instantly available for 4 years.

Clearing up the confusion over tax reform and trucker per diem

In this post I attempt to clear up the confusion over tax reform and trucker per diem. Tax Reform has contributed to much confusion within the professional truck driver community about the changes as they related to the deductibility of certain expenses. Case in point: a recent magazine article declared,

Additional good news for truckers in this bill is that HR1 does not change overnight per diems (Section 274(n)(3) of the IRC Code). That means truckers retain the ability to claim 80 percent of the $63 per diem for nights away from home.

Land Line “Tax Reform and Trucking” (January 8, 2018)

This statement is misleading and overlooks a significant difference between owner operators who are self-employed and employee (company) drivers. The article cited the retention of per diem under Internal Revenue Code Section 274(n)(3)[ii], which is correct.

IRC Section 274 and per diem

Unfortunately, the articles author misunderstood the meaning of Sec. 274, which pertains solely to the meals expense disallowance and establishes the 80% deduction limitation for per diem of a truck driver during, or incident to, the period of duty subject to the hours of service limitations of the Department of Transportation. What the article failed to articulate was that:

  • Owner Operators (self-employed drivers) claim per diem under IRC Sec 162(a)(2)[iii]
  • Company drivers (employee) previously claimed per diem as a miscellaneous itemized deduction under IRC Sec 67[iv].
    • Drivers that receive a non-taxable per diem reimbursement from their employer (trucking company) do so under IRC Sec 62(2)(a).

What tax reform eliminated

The Tax Reform and Jobs Act (H.R. 1 Sec. 11045) amended IRC Sec 67 and suspended (eliminated) miscellaneous itemized deductions for employee drivers, which includes per diem and other unreimbursed employee business expenses[v]. As a result, self-employed owner operators will still be allowed to claim per diem, but employee drivers will not.

Tax reform and company-paid per diem

The Act did not amend IRC 62(2)(a), thus trucking companies will be allowed to continue offering company-paid per diem under an accountable plan that is treated as a non-taxable reimbursement to their employees.
