If you sleep in your truck for a living, you're leaving money on the table if you're not claiming per diem. It's one of the biggest tax deductions available to owner-operators — and one of the easiest to under-use because the rules aren't obvious.

This is education, not tax advice. Always confirm the specifics with a CPA who knows trucking. But here's how it works in plain terms.

What per diem actually is

Per diem is a standard daily deduction the IRS lets you take to cover meals and incidental expenses while you're away from home overnight for work. Instead of saving every receipt for every meal, you claim a flat per-day amount for each qualifying day on the road.

For transportation workers subject to DOT hours-of-service rules, the IRS sets a special daily meal-and-incidental rate — and allows a higher deductible percentage than most other professions. That's what makes it so valuable for drivers specifically.

Important: per diem covers meals and incidentals. It does not cover fuel, lodging, tolls, repairs, or your truck. Those are separate business deductions you track on their own.

The rule that matters most: days away from home

You can only claim per diem for days you are away from your tax home overnight — long enough that you need rest before returning. A day trip where you sleep in your own bed does not qualify.

Your "tax home" is generally the metro area where your business is based, not necessarily where you live. If you're running long-haul and taking your rest breaks on the road, most of your working days will qualify.

How partial days work

Your first and last day of a trip are usually claimed at a partial rate — commonly three-quarters of the full daily amount — because you're only away for part of those days. Full travel days in between are claimed at the full rate.

Substantiation: what you have to prove

You don't need meal receipts to take the standard per diem, but you do need to prove two things:

  • The dates you were away — which days you were on the road overnight.
  • The business purpose and location — that you were traveling for work.

The good news: your logbook already does most of this. Your ELD records, settlement statements, and trip sheets create a clean, date-stamped trail of every day you were out. Keep them organized month to month and your per diem count writes itself at tax time.

This is one reason running clean, documented miles matters beyond compliance. When your paperwork is tight, your deductions are bulletproof.

Why it's worth real money

Multiply a daily meal deduction across a couple hundred nights on the road and you're looking at a substantial reduction in taxable income — every single year. For a self-employed owner-operator, that directly lowers what you owe.

It stacks on top of your other business write-offs: fuel, insurance, plates, ELD, maintenance, depreciation on the truck. Per diem is simply the one built specifically for the way trucking works.

Keep more of what you earn

Per diem is about keeping more of your income at tax time. The other half of that equation is how much you're grossing in the first place — and how much of it actually reaches your pocket.

When you lease on with ARI, you run under our motor-carrier authority and keep a true 82% of gross linehaul, with same-day pay and zero escrow. You bring home more, and clean settlement and ELD records make deductions like per diem easy to back up.
