Per Diem Calculator for Truckers: The Complete Guide
How the IRS per diem works for drivers, who can claim it, and exactly how the savings math plays out.
1. The Per Diem Formula in Three Steps
The per diem deduction is a three-step calculation — days to per diem, per diem to deductible amount, deduction to real cash savings:
Deduction = Per Diem × 80% (DOT HOS drivers)
Tax Savings = Deduction × Marginal Tax Rate
Partial days — your departure and return days — count at 75% of the full-day rate, which is where the $60 figure comes from at the standard $80 rate.
2. The 2026 Rate: $80 CONUS, $86 Outside the U.S.
The IRS publishes a special transportation industry per diem rate for workers in interstate commerce (IRS Pub 463, Chapter 6, plus the annual IRS notice). For the period from October 1, 2024 through September 30, 2026, the rate is $80 per full day in the continental United States and $86 for travel outside the U.S. The rate is updated every October — check back each fall before tax season.
3. Who Can Actually Claim It (Read This Before Filing)
Schedule C owner-operators can generally claim the per diem deduction for days spent away from their tax home. W-2 company drivers generally cannot claim unreimbursed per diem on their personal return for 2018 through 2025 — the TCJA suspended those miscellaneous deductions. The exception: if your carrier runs a per diem pay program, the benefit flows through your paycheck instead.
4. Worked Example: 250 Full Days, 60 Partial Days
A driver who spends 250 full days and 60 partial travel days away from home calculates: 250 × $80 + 60 × $60 = $23,600 total per diem. The 80% deduction gives $18,880. At a 22% marginal tax rate, that saves roughly $4,154 in real cash — without collecting a single meal receipt.
5. No Receipts Needed — Just Day Counts
The per diem method exists precisely so road workers don't have to keep restaurant receipts. Fading thermal paper is not your proof — your record of days away from home is. ELD logs, trip sheets, and dispatch records already document every night you spent on the road, which makes the per diem one of the cleanest deductions in trucking.
6. Per Diem Deduction vs. Driver Pay — Different Calculators
This page computes the tax deduction side of road life. If you want to convert a cents-per-mile offer into real take-home pay — including how a carrier per diem pay program changes your check — use the truck driver pay calculator instead. One is about what you keep at tax time; the other is about what lands in your account every week.
7. Frequently Asked Questions: Per Diem
The IRS special transportation industry rate is $80 per full day in the continental U.S. (CONUS) and $86 outside it. Partial or travel days count at 75%, which works out to $60. The rate is valid through September 30, 2026 and is updated every October.
DOT hours-of-service drivers may deduct 80% of their calculated per diem. At the standard $80/day rate, a full deductible day is worth $64; a partial day is worth $48.
Any day you travel away from your tax home — including departure and return days — counts as a partial day at 75% of the full-day rate. With the $80 CONUS rate, each partial day is worth $60 of per diem.
Self-employed owner-operators filing Schedule C can generally claim it. Company drivers (W-2) generally cannot claim unreimbursed per diem on their personal return for 2018–2025 because the TCJA suspended those deductions — unless their carrier runs a per diem pay program.
No. The per diem method replaces receipts entirely — you only need a record of your days away from home, which your ELD and trip records already back up. No shoebox of fading restaurant tickets required.
Multiply full days by the daily rate, add partial days at 75%, take 80% of that total as your deduction, then multiply by your marginal tax rate to estimate the cash savings. This per diem calculator runs all three steps live as you type.
