Driver Report IRS "time, date & place" substantiation

Our tax expert responds to a common question we receive from drivers and fleets.

Substantiated per diem provides the largest benefit to both a driver and fleet over the old cent-per-mile method. Decades before the advent of TMS software, telematics and ELD's fleets adopted cent-per-mile per diem. Why? Because it was easy to calculate and substantiate using trip sheets[i]. However, there is no correlation between the miles a driver travels and frequency of meal breaks.

Under the cent-per-mile method a driver is paid only for miles driven and not nights away from home. Although, a driver may travel 500 miles one day they may only clock 200 miles the next. In the end, the distance traveled does not affect the need to eat 3 meals a day. 

The special transportation industry per diem

The IRS introduced the Special Transportation Industry substantiated per diem to simplify tax compliance for fleets by relying on days away from home instead of miles traveled. This method accurately reflects the number of meals a driver eats and resolved the problem that driver’s regularly travel away from home and stop during a single trip at localities with differing federal M&IE rates.

  • The most beneficial aspect to a driver is that substantiated method at $69/day yields on average 25% more per diem than cent-per-mile.
  • Substantiated per diem can be earned during a 34-hour restart and unforeseen delays like detention, breakdowns, or weather.
  • A typical driver will save an additional $2,300 - $3,600 in income and payroll taxes over cent-per-mile.
  • Well-known motor carriers that utilize substantiated per diem include Averitt Express, TMC Transportation, Transport America and EPES Transport System.
  • Fleets that implement the Per Diem Plus FLEETS platform will save about 27% or $1,000 more per driver in reduced payroll and income taxes and workers compensation than cent-per-mile.

The term"per diem allowance" means a payment under a reimbursement or other expense allowance arrangement that is — (1)

  • Paid for ordinary and necessary business expenses incurred, or that the payor reasonably anticipates will be incurred, by an employee for meal and incidental expenses, for travel away from home performing services as an employee of the employer.
