Per Diem Plus for OTR Drivers

Does living in your truck make you a tax turtle?

If you are an OTR truck driver who lives in the truck you may be a classified a "tax turtle" by IRS and unable to claim travel-related expenses.

There are frequent posts on trucker social media forums and even in trucking publications that suggest merely having a post office box will be sufficient to meet the IRS’ regulations for claiming travel-related expenses.

  • Self-employed truck drivers subject to DOT hours of service regulations are entitled to claim meals and incidental expenses and other travel-related expense as a tax deduction[i].
  • To claim travel expenses a trucker must have a tax home in a real and substantial sense.
  • A trucker that fails to meet these criterion is considered a “tax turtle”, an itinerant or someone who has a home wherever he or she happens to be working[ii].  

Would John be classified a "tax turtle"?

John was an OTR truck driver who for the year under audit was away from home for 358 days, exceeded the PO Box requirements and claimed to live with his mother[iii].

Tax Court inquiry

Whether John had a tax home and whether his mother’s house was indeed his permanent residence were factual questions:

  • He made only one visit to stay with his mother during the year in question, and
    • the visit lasted three days while he served jury duty.
  • On the five other occasions on which John visited the Kansas City area, he slept in his truck parked in a casino parking lot.
  • Additionally, John kept no belongings at his mother’s house; instead, he kept them in a rented storage locker.
  • Most significantly, John bore no expenses in maintaining a home.
    • He paid no money for rent, utilities, or any other household expenses during the year under audit.

Tax Court ruling

John was a “tax turtle” who was not entitled to claim per diem and travel-related expenses.

As this case demonstrates the PO Box gambit will not survive scrutiny in a tax audit. For a self-employed truck who lives in their truck to claim travel-related expenses, like per diem, some amount of expenses must be incurred at your declared tax home. It would also be wise to spend some time there lest you risk being classified a “tax turtle”.
