Per Diem for Truck Drivers: The Tax Deduction Explained

If you're an owner-operator spending 200-plus days a year on the road, one of the largest tax deductions available to you isn't about equipment or fuel — it's the daily meal and incidental expense deduction for time spent away from home. The IRS calls this the per diem deduction, and many truckers either skip it or claim it incorrectly.

The rules aren't complicated. Here's how it works.

What Per Diem Means for Truck Drivers

"Per diem" is Latin for "per day." In tax terms, it refers to a daily allowance for meals and incidental expenses (M&IE) when you're away from home overnight for work.

The IRS allows eligible truck drivers to deduct M&IE for each qualifying day away from their tax home — either at the amount they actually spent (using receipts) or at a standard daily rate set by the IRS. The standard rate method is simpler and, for most truck drivers, produces a larger or equal deduction without requiring you to save every meal receipt.

On a high-mileage year with 220 qualifying days, the per diem deduction can represent a significant reduction in taxable self-employment income.

Who Can Claim It

Self-employed owner-operators — sole proprietors, single-member LLCs, or partners in a trucking partnership — can deduct per diem as a business expense on Schedule C. The deduction reduces your net self-employment income, which reduces both income tax and self-employment tax.

W-2 employee drivers generally cannot take this deduction on their personal tax returns. The Tax Cuts and Jobs Act of 2017 eliminated the deduction for unreimbursed employee expenses for most employees. If you receive a W-2, check with your employer — some trucking companies pay a per diem allowance as part of the compensation structure, which is excluded from your taxable wages up to the IRS limit. But if you're a W-2 driver with no employer per diem program, the deduction is not available to you personally.

If you're uncertain about your status — especially if you lease your truck through a carrier — consult a tax professional who works with truckers.

The "Away From Home" Requirement

You can only claim per diem for days you were away from your tax home long enough to require sleep or rest before returning.

Your tax home is generally the city or general area where your principal place of business is located — typically where you're based, where you pick up most loads, or where you live if you have no fixed business location. A short day run that doesn't require an overnight doesn't count, even if you crossed state lines.

What counts as a qualifying day:

• You departed your tax home area and stayed away overnight
• The nature of the work required rest — you couldn't reasonably complete the trip and return home the same day without rest

Partial days: The IRS allows partial-day counts. Under the transportation industry rules, you can count the day you leave home and the day you return home as partial days. The standard approach is to count each partial day as three-quarters of a full day for calculation purposes, though your tax preparer will confirm the treatment applicable to your situation.

The IRS Transportation Industry Rate

The IRS sets a special higher M&IE rate for workers in the transportation industry — including long-haul truck drivers — separate from the standard rates used by business travelers. This recognizes the unusual schedule and irregular meal patterns of over-the-road work.

The rate is updated annually. The IRS typically publishes the new rates each fall for the following tax year, via an IRS Notice (for example, IRS Notice 2024-68 sets the rates applicable for 2024-2025). The special transportation industry rate for travel within the contiguous United States has historically been in the range of $69–$80 per day in recent years — but you must verify the current rate for the tax year you're filing by checking the applicable IRS Notice or asking your tax preparer. Do not use a prior year's rate and assume it hasn't changed.

For days traveling in Alaska, Hawaii, or internationally, different rates apply. Foreign per diem rates are set by the U.S. Department of State.

The 80% limit: The IRS limits the meal deduction to 80% of the allowable amount for transportation workers. If the applicable per diem rate is $80/day, your deductible amount per qualifying day is $64 (80% of $80).

Running the Numbers

Here's how the calculation works once you have the applicable rate:

Say the IRS transportation industry rate for your filing year is $80/day, and you were away from your tax home for 215 full days and 12 partial days (treated as three-quarter days):

That $14,336 reduces your net Schedule C income. For an owner-operator with meaningful self-employment tax exposure, this is a material deduction — not a rounding error.

Run the actual numbers with your tax preparer using the correct rate for your filing year and your verified qualifying day count.

Actual Expenses vs. Standard Rate: Which to Use

You have a choice each tax year:

Standard per diem rate: You deduct the IRS transportation industry rate for each qualifying day without saving meal receipts. Simpler, and for most truck drivers, this produces a larger deduction than tracking actual meal spending.

Actual expense method: You deduct what you actually spent on meals, supported by receipts. This is rarely beneficial for truck drivers unless you're consistently spending significantly above the IRS rate.

Most owner-operators use the standard rate. You can switch methods, but only at the start of a tax year — you can't change methods mid-year.

What Records You Need

Using the standard rate doesn't require you to save meal receipts, but it does require records that establish your qualifying days away from home. You need documentation showing:

• When you left your tax home area
• Where you were working (general location or delivery city)
• When you returned home
• The business purpose — which for a truck driver is inherent in the load

Your load records are the primary documentation. Rate confirmations, bills of lading, and delivery receipts together show departure dates, destination cities, and return dates — exactly what the IRS needs to see. ELD records and logbook data add corroborating location and time data.

The cleaner your dispatch and load records are, the simpler it is for your tax preparer to calculate and document the deduction. If your loads are tracked in a trucking management platform, you have date-stamped records for every trip automatically.

What "Incidentals" Covers

The "incidentals" portion of M&IE includes minor work-related expenses like tips to hotel staff, bellhops, and similar service staff. These are modest amounts, but they're built into the IRS per diem rate automatically. You don't need to track them separately when using the standard rate — they're covered.

Common Mistakes

Claiming days you were home. This is the most common audit issue. Your documentation needs to clearly show which days you were away overnight. Days where you made a local delivery and returned home the same day don't qualify.

Using the wrong rate. Per diem rates change. Using last year's rate when you should be using the current year's rate is an easy error that your tax preparer can catch — if you're using a preparer who knows truck driver returns.

Forgetting partial days. The day you leave and the day you return both count as partial days. Not counting them at all understates your deduction.

Not tracking qualifying days consistently. If your records are incomplete — some loads logged, some not — your preparer can only claim what's documented. Expense tracking that captures every load's dates automatically is the safest approach.

Work With a Trucking-Focused Tax Preparer

Per diem rules for truck drivers have specific wrinkles — what counts as your tax home, how to handle irregular schedules, how partial days are treated — that general tax preparers sometimes get wrong in either direction. A preparer who regularly handles truck driver returns knows the Publication 463 rules and the transportation industry notice rates.

The deduction is legitimate and substantial. Getting it right matters.

Truck Command keeps your load history, trip dates, and fuel logs in one place, so per diem documentation is a natural byproduct of normal record-keeping — not a separate project you have to reconstruct at tax time. Plans start at $20/month with a 14-day free trial — no credit card required.

You earned those days on the road. The per diem deduction is the IRS acknowledging that. Count them, document them, and take what's yours.
