Trucker Per Diem Calculator

The current IRS special transportation rate, the 80% DOT rule, and ¾ partial days — with the owner-operator vs company-driver rules most sites still get wrong.

Estimate your per diem deduction

Answer two quick questions first — they decide whether the deduction applies to you at all.

1. How are you paid?
2. Were these travel days subject to DOT hours-of-service limits?
3. Method
Before you count on this number: you need a regular tax home (itinerant drivers with no home base generally don't qualify) · the trip must require sleep or rest away from home · keep records of dates, places, and business purpose · you can't also deduct reimbursed amounts. This is a planning estimate, not tax advice — confirm with a tax professional who knows trucking.
Rates: IRS Notice 2025-54 ($80 CONUS / $86 OCONUS / $5 incidentals, effective Oct 1, 2025) · ¾ partial-day method: IRS Pub 463 · 80% DOT limit: IRC §274(n)(3) · Reviewed July 2026

How trucker per diem actually works in 2026

Instead of saving every meal receipt, drivers can use the IRS special transportation-industry rate: a flat daily amount for meals and incidental expenses while traveling away from home. Effective October 1, 2025 that rate is $80 per day in the continental U.S. and $86 outside it (IRS Notice 2025-54).

Two adjustments do the real work. First, on the day you leave and the day you get home you claim ¾ of the rate — $60 instead of $80 (you may instead prorate by any reasonable method applied consistently, per Pub 463). Second, the deduction is limited to 80% of the total for drivers subject to DOT hours-of-service limits — a special carve-out in the tax code; most other workers only get 50%.

Owner-operators vs company drivers

This is where most outdated pages will cost you money or get you in trouble. Owner-operators (Schedule C) claim per diem as a business expense — that's what this calculator estimates. Company drivers lost the federal deduction for unreimbursed travel back in 2018, and the 2025 tax law made that change permanent. If you're W-2, the per diem conversation is about your carrier's pay plan, not your tax return.

The $5 incidentals-only rate

If you incur no meal costs on a travel day (or deduct actual meal receipts instead), there's a separate $5/day incidentals-only rate. It's an either-or with the $80 rate for any given day — never both — and it does not take the 80% haircut, because it isn't a meal expense.

Worked example: an owner-operator under HOS rules with 220 full days and 30 partial days in the lower 48: (220 × $80) + (30 × $60) = $19,400 → × 80% = $15,520 estimated deduction.

Every October the IRS can change the rate. This page carries the notice number and a reviewed date, and we update it when the new notice lands — that's the whole point of this site.
