Per diem is one of the most misunderstood parts of truck driver compensation. Some carriers use it as a way to reduce driver tax liability. Some use it to lower their payroll tax burden. Some pay it correctly. Some do not.

Whether you are a carrier structuring a driver pay package, an owner operator calculating your own deductions, or an accountant trying to make sure the books reflect reality, getting per diem for truck drivers right matters both for compliance and for making sure drivers are actually getting the full value of the benefit.

This guide covers the current IRS rates, how per diem works differently for company drivers and owner operators, what accountable and non-accountable plans mean in practice, and how to track it correctly in your accounting system.

Note: This guide is for general informational purposes. Tax rules change and individual situations vary. Always consult a licensed CPA or enrolled agent familiar with trucking before making tax or compensation decisions.

What Is the IRS Per Diem Rate for Truck Drivers in 2026

The IRS sets a standard per diem rate specifically for transportation workers subject to DOT hours-of-service regulations. This rate covers meals and incidental expenses while traveling away from the driver's tax home overnight.

The partial day rate applies on departure days and arrival days when the driver is not away from home for the full 24-hour period. It does not apply to days the driver is at home.

The 80% deductibility rate is a special provision under IRC Section 274(n)(3) for transportation workers. Most other businesses can only deduct 50% of meal expenses. DOT-regulated drivers get the higher rate because of the nature of their work and the difficulty of keeping individual meal receipts on the road.

Using the standard per diem rate means you do not need receipts for individual meals. You need a log showing which days you were away from your tax home overnight. ELD records and trip logs both satisfy this requirement.

How Do Carriers Pay Per Diem to Company Drivers and What Are the Tax Implications

When a carrier chooses to pay company drivers a per diem allowance, the structure of that payment determines whether it creates a tax benefit for the driver or just increases their taxable gross pay.

There are two fundamental ways carriers handle per diem for W-2 company drivers:

Option 1: Built Into the Mileage Rate

The most common approach. The carrier pays drivers a higher gross rate per mile but labels a portion of it as per diem. For example, instead of paying $0.60 per mile as taxable compensation, the carrier pays $0.50 per mile as taxable compensation plus $0.10 per mile as a non-taxable per diem allowance.

The benefit: the per diem portion is not subject to federal income tax, Social Security, or Medicare withholding, as long as it is paid under an accountable plan and does not exceed the IRS rate. The driver takes home more of their gross pay.

The catch: lower taxable wages mean lower Social Security credits, which affects retirement benefits. It also means the driver's W-2 shows lower wages, which matters for mortgage applications and other income verification purposes. Some drivers prefer straight taxable pay for this reason.

Option 2: Separate Per Diem Reimbursement

The carrier pays the driver's base rate plus a separate per diem allowance on top of it. The per diem is tracked separately, reported on the W-2 in Box 12 under Code L if under the IRS limit, and is non-taxable to the driver up to the daily cap.

This approach is cleaner from an accounting standpoint because the per diem is clearly visible as a separate line item rather than embedded in a blended mileage rate.

What Is the Difference Between Accountable and Non-Accountable Per Diem Plans

This distinction determines whether per diem paid by a carrier to company drivers is tax-free or taxable. Getting this wrong creates payroll tax problems for the carrier and unexpected tax bills for the driver.

For a trucking company to run an accountable plan, drivers need to document their travel (ELD records, trip logs, or BOL timestamps work for this purpose), the per diem must be tied to actual business travel, and any per diem paid above the IRS daily limit must be treated as taxable wages. Most well-run carriers already meet these requirements without realizing it because ELD records automatically document away-from-home travel.

Can Owner Operators Claim Per Diem Differently Than Company Drivers

Yes, and significantly so. Owner operators have more flexibility and more potential value from per diem than company drivers do.

For owner operators filing Schedule C:

• Per diem is claimed directly as a business deduction, not as an employee reimbursement.

• The full $80 per day rate applies for days away from the tax home overnight, with $60 for partial days.

• 80% of the per diem total is deductible under the special DOT rate, versus 50% for most other businesses.

• No receipts are required for individual meals. A log of away-from-home days is sufficient.

• The deduction reduces net self-employment income, which in turn reduces both income tax and self-employment tax.

For a W-2 company driver:

• If the employer pays per diem under an accountable plan, the benefit is built into the pay package and does not require a separate tax deduction.

• If the employer does not pay per diem, W-2 drivers cannot deduct unreimbursed per diem expenses at the federal level following the 2017 Tax Cuts and Jobs Act. Some states still allow this deduction, so state returns may differ.

• A W-2 driver cannot claim the same per diem that their employer has already paid them. Double dipping is not allowed.

The practical implication: owner operators who are on the road 250 or more days per year have access to a deduction worth $16,000 or more annually just from per diem, before any other business expenses. That is a significant tax advantage compared to being a W-2 employee at a carrier that does not offer an accountable per diem plan.

How Does Per Diem Affect Driver Gross Pay and Net Take-Home

This is where many drivers get confused, particularly when comparing job offers from carriers with different pay structures.

Consider two offers for a driver running 2,500 miles per week, 50 weeks per year (125,000 miles annually):

Same gross pay, but Carrier B's driver takes home roughly $3,700 more per year purely from the per diem structure. This is why the advertised mileage rate alone is not enough information to compare job offers. A $0.58 per mile offer with an accountable per diem plan may net the driver more than a $0.62 offer without one.

What Records Must Carriers Keep for Per Diem Reimbursements

For carriers operating under an accountable plan, the IRS requires documentation that per diem payments have a valid business purpose and are tied to actual away-from-home travel. In practice, trucking carriers already generate most of this documentation automatically.

• ELD records or trip logs showing dates and locations of travel away from the driver's tax home. These automatically document the business purpose and travel days.

• Per diem payment records by driver, showing the daily rate paid, total days paid, and total amount per settlement period.

• Settlement sheets showing per diem as a distinct line item separate from taxable mileage pay.

• W-2 records showing per diem reported in Box 12 under Code L for amounts within the IRS daily limit.

• Payroll records demonstrating that amounts above the IRS daily limit were treated as taxable wages.

These records need to be retained for at least four years in most jurisdictions, both for IRS audit purposes and for state payroll tax compliance. Carriers whose per diem programs are not properly documented face the risk of having the entire per diem amount reclassified as taxable wages, creating back payroll tax liability plus penalties.

How Fintruck Handles Per Diem Payouts and Tracks Them Correctly in Accounting

Per diem creates a specific accounting challenge for carriers: it needs to show up on driver settlement sheets as a distinct line item, post to the correct payroll expense accounts in the general ledger, and flow through to W-2 reporting in the correct boxes at year end. Generic accounting software was not built to handle this workflow. Trucking-specific software is.

Fintruck handles per diem as part of the integrated driver settlement and payroll workflow.

• Per diem tracked as a distinct settlement line item so it is never embedded in a blended rate or lost in net pay. Drivers and the back office can always see exactly what was paid as taxable wages and what was paid as per diem.

• Native Datatruck TMS integration pulls trip data including away-from-home days automatically, so per diem calculations are based on actual travel records rather than manual entry.

• Correct account coding posts per diem in the right payroll expense category, separate from taxable driver wages, so your P&L reflects the true cost of each type of compensation accurately.

• Driver settlement reconciliation matches per diem payouts against load and trip records, so the per diem paid always ties back to actual documented travel. This is what the IRS requires for accountable plan compliance.

• Year-end export for CPA and payroll provides a clean summary of per diem paid per driver, taxable wages, and settlement totals, making W-2 preparation straightforward rather than a reconciliation project.

Setup takes 5 to 9 minutes. Start your free trial and get per diem tracked correctly from the first settlement.

Frequently Asked Questions

What is the IRS per diem rate for truck drivers in 2026?

The current IRS per diem rate for DOT-regulated truck drivers is $80 per full day and $60 per partial day within the continental United States, effective October 1, 2024. The rate outside the continental United States is $86 per day. DOT-regulated drivers can deduct 80% of this amount, compared to 50% for most other businesses.

How do carriers pay per diem to company drivers and what are the tax implications?

Carriers typically structure per diem one of two ways: embedded in the mileage rate where a portion of the per-mile pay is designated as non-taxable per diem, or as a separate flat daily reimbursement on top of mileage pay. When paid under an accountable plan and within the IRS daily limit, per diem is non-taxable to the driver and not subject to FICA or FUTA for the carrier. Amounts above the IRS daily limit must be treated as taxable wages.

What is the difference between accountable and non-accountable per diem plans?

An accountable plan meets IRS requirements: the per diem has a business purpose, travel is documented, and excess amounts above the daily limit are returned or treated as taxable wages. Per diem under an accountable plan is non-taxable to the driver. A non-accountable plan does not meet these requirements, meaning all per diem paid is treated as taxable wages regardless of its label on the pay stub.

Can owner operators claim per diem differently than company drivers?

Yes. Owner operators claim per diem directly as a business deduction on Schedule C at $80 per full day, deducting 80% of the total. The deduction reduces both income tax and self-employment tax. W-2 company drivers cannot deduct unreimbursed per diem at the federal level under current law, so they depend on their employer's per diem plan to access the tax benefit.

How does per diem affect driver gross pay and net take-home?

Per diem reduces the taxable portion of a driver's compensation without reducing their gross pay. A driver paid $75,000 under a structure with $12,500 in non-taxable per diem pays income tax and FICA only on $62,500, saving roughly $3,700 compared to a driver paid $75,000 in fully taxable wages. This is why comparing mileage rates alone is not enough when evaluating carrier compensation packages.

What records must carriers keep for per diem reimbursements?

ELD records or trip logs documenting away-from-home travel, per diem payment records by driver showing rate and days paid, settlement sheets with per diem as a distinct line item, W-2 records showing per diem in Box 12 Code L, and payroll records showing that amounts above the IRS limit were treated as taxable wages. These should be retained for at least four years.

How does Fintruck handle per diem payouts and track them correctly in accounting?

Fintruck tracks per diem as a distinct line item in driver settlements, pulls away-from-home travel data from the Datatruck TMS to support accountable plan documentation, posts per diem to the correct payroll expense accounts separately from taxable wages, and provides year-end export summaries that make W-2 preparation straightforward. Per diem is never embedded in a blended rate or mixed into other settlement lines.
