How to Claim Per Diem on Taxes as a Truck Driver

To claim per diem on your taxes as a truck driver, you have to be self-employed: count each day you were away from your tax home overnight, multiply by the IRS special transportation industry rate ($80 per day in the continental U.S. and $86 outside it for the period beginning October 1, 2025), take 80% of that total, and report the result on Schedule C, Line 24b. W-2 company drivers cannot deduct per diem on their own returns at all; that deduction was suspended in 2018 and made permanent by the One Big Beautiful Bill Act of 2025.

Can You Actually Claim It

Two things decide whether the per diem deduction is available to you: how you’re classified, and whether you have a tax home.

If you operate your own trucking business and file Schedule C, you’re in. The IRS specifically allows self-employed individuals to use the per diem rate to substantiate meal expenses instead of tracking individual receipts.¹ The deduction reduces your net profit, so it cuts both your income tax and your self-employment tax.

If you’re a W-2 employee driver, you’re out. The Tax Cuts and Jobs Act of 2017 suspended the miscellaneous itemized deduction for unreimbursed employee expenses starting in 2018, and the One Big Beautiful Bill Act of 2025 made that permanent. Filing Form 2106 for per diem will not produce a valid deduction. The only per diem benefit available to a company driver is one paid by the employer, and that’s covered further down.

You Need a Tax Home

Your tax home is wherever your main place of business sits, not necessarily where your family lives. For most drivers, that’s the city where your home terminal or dispatching center is located. If your family lives in Tucson but your terminal is in Phoenix, Phoenix is your tax home. You can deduct meals for days on the road away from Phoenix, but not for time at the terminal itself.

The deduction only applies when you travel away from that tax home long enough to need sleep or rest before you can safely continue. Same-day round trips don’t count, no matter how long.

The Itinerant Problem

If you have no regular place of business and no fixed place where you regularly live, the IRS treats you as an itinerant, and itinerants can never be “away from home” because they have no home to be away from. No tax home means no travel deduction, including per diem.²

The IRS applies two tests in order. Do you have a regular or principal place of business? If yes, that’s your tax home. If no, do you have a place where you regularly live? If both answers are no, you’re itinerant.³ A driver who lives in the cab full-time with no apartment or house and picks up loads from various terminals fits that profile. Maintaining a residence you regularly return to and reporting to a home terminal is what keeps most drivers on the safe side of this line.

The Rate and the 80% Limit

The IRS publishes a simplified per diem rate for workers under Department of Transportation hours-of-service limits. Truck drivers qualify. Unlike the standard federal per diem, which varies by city, the transportation industry rate is a flat number no matter where you drive.

For the period beginning October 1, 2025, the rates from IRS Notice 2025-54 are:⁴

$80 per day for travel within the continental United States (CONUS)
$86 per day for travel outside the continental United States (OCONUS)

These cover meals and incidental expenses only. Incidentals include tips for servers and luggage handlers, and laundry, dry cleaning, and pressing of clothing on the road. Lodging is handled separately, though most long-haul drivers sleep in the cab and have no lodging cost to track.

Then the limit. You can’t deduct the full per diem amount. Federal law caps the meal deduction at 80% for individuals subject to DOT hours-of-service rules.⁵ The standard limit for everyone else is 50%, so 80% is actually a favorable exception for transportation workers. It still means one-fifth of your calculated per diem drops off before it reaches your return.

How to Calculate and Report It

Three steps: count your travel days, apply the rate, take 80%.

Step 1: Count travel days. Identify every day you were away from your tax home on business during the tax year. Full days get the full rate. The first and last day of each trip are partial days at 75% of the daily rate.⁶ If you leave Monday morning and return Thursday evening, Monday and Thursday are 75% days and Tuesday and Wednesday are 100% days.

Step 2: Apply the rate. Multiply full days by $80 (or $86 OCONUS) and partial days by 75% of that rate. Add them up for your gross per diem.

Step 3: Take 80%. Multiply the gross total by 0.80. That’s your deductible per diem.

Here’s what that looks like with real numbers. Say you had 250 full travel days and 60 partial days in the continental U.S.:

Full days: 250 × $80 = $20,000
Partial days: 60 × $60 (75% of $80) = $3,600
Gross per diem: $23,600
Deductible amount: $23,600 × 0.80 = $18,880

Report the final figure on Schedule C, Line 24b, “Deductible meals.”⁷ Because the deduction lowers net profit from self-employment, it reduces both income tax and the self-employment tax on Schedule SE. At the 15.3% combined SE tax rate, a deduction of $18,880 saves over $2,600 in self-employment tax alone, before income tax savings.

Keep per diem separate from other meals. Local business meals that don’t involve overnight travel away from your tax home fall under the standard 50% limit, not 80%. Don’t combine them on the same line.

Records You Have to Keep

The per diem method spares you the shoebox of restaurant receipts. It does not spare you documentation. You still have to prove the time, place, and business purpose of each trip. Without records showing you were actually on the road, the whole deduction can be thrown out in an audit.

At a minimum, your records should show:

Date and time of departure from your tax home for each trip
Date and time of return
Destinations during the trip
Business purpose (hauling freight for a client, delivering a load to a specific location)

Electronic logging device records, trip sheets, dispatch records, and bills of lading all do the job. What matters is that the records let you distinguish full days from partial days and confirm you were away overnight. A log showing you left Dallas at 6 a.m. on March 3 and returned at 8 p.m. on March 7 gives you two partial days and three full days with destinations attached.

Hold onto these for at least six years. The IRS can generally audit returns from the past three years, but that stretches to six if gross income is understated by more than 25%. Electronic records have to stay accessible and readable; a proprietary file format the IRS can’t open won’t satisfy the requirement.

If You’re a W-2 Company Driver

Employee drivers can’t claim per diem on their own returns. That path is closed and now permanently so. But per diem isn’t irrelevant to you; it just has to come through the employer.

When an employer pays per diem under an accountable plan, the payments are excluded from your taxable wages on Form W-2. The money reaches you tax-free, which produces the same economic result as a deduction without you claiming anything on your return.⁸ An accountable plan has to meet three requirements: the expenses are business-related, you substantiate them to the employer within a reasonable time, and any excess reimbursement is returned.

If the plan fails any of those tests, it becomes a nonaccountable plan, and the entire per diem payment is added to your taxable wages in Box 1 of the W-2. The same treatment applies to any amount the employer pays above the federal rate; the excess is taxable income even if the base is excluded. If you receive no per diem at all as an employee, negotiating it into your compensation is the only federal mechanism available to capture the benefit.

Mistakes That Get the Deduction Thrown Out

Per diem for truckers draws IRS attention because the dollar amounts are large and inflating travel days is easy to attempt. A few patterns come up repeatedly.

Claiming 365 travel days. Nobody is on the road every day of the year. A return showing per diem for every calendar day with no home time, holidays, or reset periods invites questions about how that’s possible under DOT hours-of-service rules. Your day count should track your actual driving schedule.

No supporting documentation. A $20,000 deduction backed by a handwritten note saying “250 days on the road” won’t survive an examination. ELD records, dispatch logs, and dated fuel receipts that show your geographic location on specific dates create a paper trail that holds up.

Using the wrong rate or skipping the 80% limit. Some drivers deduct the gross per diem without applying the 80% reduction, or pull a rate from a prior year’s notice. Both errors overstate the deduction. Confirm you’re using the current rates from Notice 2025-54 and applying the 80% cap to the total.⁴

Claiming per diem without a tax home. If you can’t show a regular place of business or a residence you regularly return to, the IRS can reclassify you as itinerant and disallow the entire deduction.³ It’s the threshold question, and losing it wipes out everything else on the calculation.
