Who qualifies
Self-employed drivers (owner-operators, lease-purchase) subject to DOT hours-of-service rules, traveling away from their tax home long enough to require rest. Two pieces matter:
- 'Away from home' means away from your tax home overnight, trips requiring sleep or rest per DOT rules, not day runs that end in your own bed
- W-2 company drivers cannot deduct per diem themselves under current law (the old employee deduction was suspended), they only benefit if their carrier runs a per diem pay program. This guide's deduction math is for the self-employed
The rate and the 80% rule
Transportation workers get a special standardized rate, for recent years it has been in the $69–$80 per full day range for travel within the continental U.S. (higher outside it), adjusted periodically in IRS notices; confirm the current figure at filing. The quirk that surprises everyone: DOT-covered workers deduct 80% of the per diem amount, not 50% like ordinary business meals, a significant upgrade Congress wrote specifically for transportation.
Partial days, the days you leave and the days you return, take 75% of the daily rate under the standard method. Leave Monday afternoon, return Friday morning: three full days plus two partial days, not five and not three.
What per diem is actually worth: a worked example
A solo owner-operator out 280 days: say 240 full days and 40 partial days. At an illustrative $80 rate: (240 × $80) + (40 × $80 × 75%) = $19,200 + $2,400 = $21,600 of per diem, deductible at 80% = $17,280 off taxable income. For a driver in a combined ~30% bracket (income plus self-employment tax effects), that's roughly $5,000 of real tax saved, from a deduction that requires no receipts, only proof of the nights. Undercounting days by sloppy recordkeeping is literally leaving $18 of deduction per missed day.
The records that support it
- Your ELD logs, the cleanest possible evidence of nights away and duty status; keep the year's logs exported and archived
- A trip calendar reconciling days out: full days, partial days, home days, maintained monthly, not reconstructed in March
- Settlement statements and dispatch records corroborating the trips
No meal receipts needed under the standard rate, that's its entire point. (Actual-expense method exists as an alternative, but for solo drivers it almost never beats the standard rate and it resurrects the receipt-hoarding problem.)
The tax home trap
Per diem requires being away from a tax home, your regular place of business or residence. Drivers who live in the truck full-time with no fixed residence can be ruled 'itinerant,' with no tax home, and therefore never 'away,' and therefore zero per diem. If your situation is anywhere near this (gave up the apartment, mail goes to a relative), get real advice before claiming a year of per diem; this exact issue is a recurring audit loss. Maintaining a genuine residence, costs, ties, time there between runs, is what preserves the deduction.
Per diem and your other numbers
Per diem interacts with the rest of the return: it reduces income tax and self-employment tax base (it's a business deduction on Schedule C), stacks with everything in the full deduction list ( Owner-Operator Tax Deductions: The Complete List ), and, worth knowing, does not reduce the income a lender sees if they're working from bank deposits, though it does reduce the net income on the return they'll ask for. Drivers planning a mortgage sometimes moderate deductions in the qualifying years; that's a strategy conversation, not a default.
Frequently asked questions
Is there an app or do I just count nights?
Your ELD already counts them, the job is a monthly fifteen-minute reconciliation of days out, which we fold into trucking clients' regular bookkeeping so the count is audit-ready by January. Trucking
Do local and regional drivers get anything?
Only nights genuinely away from the tax home count. A regional driver out two nights a week still accumulates 100+ compensable days a year, smaller than OTR money, far from nothing.
My carrier pays me per diem, what does that change?
Carrier per diem programs (for leased-on or W-2 drivers) pay part of compensation as untaxed per diem reimbursement, you can't then deduct the same days yourself. Owner-operators booking their own deduction: make sure a factoring or fleet program isn't already reimbursing meals somewhere in the settlement.
