Truck Driver Per Diem Deduction Guide: IRS Standard Meal Allowance for CPAs & Drivers

For commercial truck drivers and owner-operators traveling over the road, meal and incidental expenses represent one of the largest ongoing operational costs. To simplify bookkeeping and eliminate the administrative burden of collecting and storing hundreds of individual diner and truck-stop food receipts, the Internal Revenue Service provides a standardized per diem deduction specifically tailored to transportation industry workers.

Codified under Internal Revenue Code (IRC) § 274(n)(3), the special transportation worker per diem deduction offers a unique 80% deduction rate—significantly more generous than the standard 50% business meal deduction available to regular business travelers.

IRS Per Diem Rates for Transportation Workers: CONUS & OCONUS Benchmarks

The IRS updates federal per diem rates annually in late September via an official Revenue Procedure. For commercial drivers operating under Department of Transportation Hours of Service, the benchmark rates are established as follows:

• CONUS Rate ($80 Per Full Day): For all commercial travel within the continental United States (48 lower states), the special transportation worker standard meal allowance is $80 per day. At the 80% statutory deduction rate, this equals a tax deduction of $64.00 per full qualifying day on the road.
• OCONUS Rate ($86 Per Full Day): For commercial travel outside the continental United States (including Alaska, Hawaii, Canada, and US territories), the rate increases to $86 per day. At 80%, this equals a tax deduction of $68.80 per full qualifying day.
• Incidental Expenses Included: The transportation per diem rate strictly covers Meals and Incidental Expenses (M&IE). Incidental expenses include fees and tips given to food servers, luggage handlers, and hotel staff. Lodging expenses are not included in this rate and must be substantiated separately if incurred.

The Three Non-Negotiable Qualifications for Claiming Per Diem

To legally claim the 80% transportation per diem deduction, an owner-operator or commercial driver must satisfy three explicit statutory criteria:

• Governed by DOT Hours of Service (HOS): The taxpayer must be subject to the Federal Motor Carrier Safety Administration (FMCSA) Hours of Service regulations under 49 CFR Part 395. This applies to commercial operators driving vehicles over 10,000 lbs GVWR or transporting placarded hazardous materials.
• Overnight Travel Away from Tax Home: The trip must require substantial sleep or rest away from the driver primary tax home to meet the demands of their work. A local or regional driver who completes their shift and returns home to sleep in their own bed cannot claim per diem, regardless of how many hours they worked.
• Established Tax Home: The driver must maintain a regular, physical tax home (such as a permanent residence where they incur ongoing living costs). Drivers who live full-time in their commercial tractor without maintaining a permanent residence are classified by the IRS as itinerant workers and are disqualified from claiming per diem deductions.

The 75% Partial-Day Rule for Departure and Return Days

A common mistake made by both drivers and generalist accountants is claiming 100% of the per diem rate for every day of a haul. Under IRS rules, partial travel days must be prorated:

On the day a driver departs their tax home, and on the day they return home, the IRS permits exactly 75% of the daily allowance. For travel within the continental United States ($80 full rate), the partial day allowance is $60.00 ($80 × 75%). When multiplied by the 80% allowable tax deduction, this yields an allowable tax write-off of $48.00 per partial day.

1. Identify trip start date: Apply the 75% partial-day rate ($60 in CONUS) for the departure day.
2. Identify full travel days: Apply the 100% full-day rate ($80 in CONUS) for each calendar day spent entirely away from home.
3. Identify trip return date: Apply the 75% partial-day rate ($60 in CONUS) for the day of return.
4. Sum total allowable per diem allowances and multiply by 80% (0.80) to establish the final deductible amount on federal tax schedules.

Owner-Operators vs. Company Drivers: The Tax Cuts and Jobs Act Impact

The Tax Cuts and Jobs Act (TCJA) fundamentally altered who can claim the per diem deduction on personal tax returns:

Independent Owner-Operators (1099-NEC, Sole Proprietorships, Single-Member LLCs): Independent drivers continue to claim the 80% per diem deduction directly as an ordinary and necessary business expense on Schedule C (Form 1040), Line 24b.

W-2 Company Drivers: TCJA eliminated all unreimbursed employee business expenses (previously claimed on Form 2106 and Schedule A). Consequently, company drivers cannot deduct per diem on their individual tax returns. A company driver can only receive per diem tax advantages if their motor carrier employer administers an official, non-taxable "accountable plan" that reimburses per diem directly on their payroll stubs.

ELD Telematics and IRS Audit Substantiation

Under IRS Revenue Procedure 2011-47, taxpayers using standard per diem rates do not need to retain meal receipts. However, the driver must maintain rigorous substantiation proving they were legally away from their tax home on the claimed dates.

Electronic Logging Device (ELD) records represent the primary evidence examined during IRS income tax audits. Auditors will verify that ELD duty logs corroborate midnight-to-midnight location pings, on-duty driving intervals, and sleeper berth rest periods occurring outside the driver metropolitan tax home area.

Reporting Per Diem Alongside Form 2290 HVUT Deductions

When assembling annual federal tax filings for commercial motor carriers, practitioners must properly allocate vehicle excise taxes alongside driver meal deductions:

While driver per diem is reported on Schedule C Line 24b (or Form 1065 Line 20 / Form 1120-S Line 19), annual Heavy Vehicle Use Tax (HVUT) paid via Form 2290 is reported on Schedule C Line 23 as "Taxes and licenses" (or Form 1065 Line 14 / Form 1120-S Line 12). Both deductions directly reduce net taxable business income and self-employment tax obligations.
