Does the Special Transportation Rate Apply to You?
Before multiplying a daily rate by the number of days on the road, confirm whether the special transportation-industry method fits the taxpayer and the trip.| Check | What to confirm | Why it matters |
|---|---|---|
| Tax home | Identify your regular place of business or post of duty under the IRS rules rather than assuming your personal residence is automatically your tax home | A travel deduction generally depends on being away from your tax home |
| Away-from-home travel | Confirm the business trip requires you to be away from the general area of your tax home long enough to require sleep or rest to meet the demands of the work | Ordinary local meals do not become travel expenses simply because you are working |
| Transportation-industry status | Confirm your work directly involves moving people or goods by truck and regularly involves travel away from home with stops in localities that can have different federal M&IE rates | Rev. Proc. 2019-48 defines who may use the special transportation-industry rate |
| DOT hours-of-service status | Determine whether the meal was consumed during or incident to a duty period for which applicable DOT hours-of-service limits were in effect | This affects whether the 80% meals limitation may apply |
| Owner-operator or employee | Identify whether you are self-employed or a W-2 company driver and whether an employer reimbursement arrangement applies | The way the amount is deducted or reimbursed can differ materially |

2026 Per Diem Rates for Truck Drivers and What They Actually Mean
The key 2026 rules are connected, but they should not be blended together. The published M&IE rate, the applicable meal-deduction percentage, partial-day treatment, and filing status each answer a different question.CURRENT RATE · Through September 30, 2026 · Qualifying transportation workers
The Current Transportation M&IE Rate Is $80 CONUS / $86 OCONUS
IRS Notice 2025-54 sets the special transportation-industry meal and incidental expense rates at $80 per day for any locality of travel within the continental United States and $86 per day for travel outside the continental United States. The notice applies to the 2025–2026 special per-diem period. These are M&IE substantiation rates. They are not flat lodging allowances for a self-employed driver, and they do not automatically become the amount ultimately deducted on the return. What to do: use the applicable $80 or $86 amount only after confirming that the taxpayer and trip qualify for the transportation-industry method.REVIEW · Each qualifying meal · Drivers subject to DOT HOS limits
The 80% DOT Hours-of-Service Rule Is Separate From the Daily Rate
The IRS generally limits deductions for business meals, but the percentage increases to 80% for qualifying meals of individuals subject to Department of Transportation hours-of-service limits. The Schedule C instructions specifically include interstate truck operators subject to DOT regulations among the workers who can fall within this rule. That means $64 is not the IRS truck-driver per-diem rate. It can be the result of applying an 80% meals limitation to an $80 qualifying M&IE amount: $80 × 80% = $64 Keeping those two figures separate matters. The published rate establishes the M&IE amount used in the calculation; the meal percentage is a separate limitation that may apply after the underlying travel qualifies. What to do: document whether the applicable DOT hours-of-service condition is met before applying the 80% percentage.CALCULATION · Departure and return days · Self-employed M&IE method
Three-Fourths Is One Permitted Partial-Day Method
Rev. Proc. 2019-48 permits partial travel days to be prorated using three-fourths of the applicable M&IE rate. It also permits another proration method when that method is consistently applied and consistent with reasonable business practice. The illustration below uses the three-fourths method. Using the three-fourths method at the current $80 CONUS transportation rate, a qualifying partial day is: $80 × 3/4 = $60 For example, consider a qualifying self-employed owner-operator with two full CONUS travel days and two qualifying partial days, using the three-fourths method:| Travel day | M&IE amount |
|---|---|
| Full day 1 | $80 |
| Full day 2 | $80 |
| Partial departure day | $60 |
| Partial return day | $60 |
| Total M&IE amount before the meal limitation | $280 |

Owner-Operators and W-2 Company Drivers Do Not Claim Per Diem the Same Way
A self-employed owner-operator may use the applicable M&IE method when the travel and other requirements are met. A typical W-2 company driver has a different federal tax position. Current 2026 IRS guidance states that the disallowance of miscellaneous itemized deductions subject to the 2%-of-AGI floor - including ordinary unreimbursed employee travel expenses - was made permanent, subject to limited statutory exceptions. That does not mean employer per-diem arrangements disappeared. An employer may reimburse qualifying business travel under an accountable plan. When the requirements are satisfied, amounts up to the properly substantiated amount can receive different wage treatment than payments made under a nonaccountable arrangement. Rev. Proc. 2019-48 requires substantiation of travel and addresses treatment of excess reimbursements. If your employer pays a meals allowance for truck drivers, do not assume the allowance is automatically a personal tax deduction or automatically taxable wages. The reimbursement arrangement, records, amount, and employee’s facts matter. What to do: W-2 drivers should review the employer reimbursement arrangement before treating a per-diem payment as a personal deduction.METHOD · Every trip · Meals, incidentals, and lodging
Per Diem, Actual Meal Costs, and Lodging Are Different
For a qualifying self-employed taxpayer, the standard M&IE method can be used instead of substantiating the actual dollar amount of qualifying meals and incidental expenses. It does not eliminate the requirement to establish the time, place, and business purpose of the travel. Lodging is a separate issue. A self-employed driver should not treat the $80/$86 transportation M&IE rate as though it includes a flat lodging deduction. What to do: choose the permitted meal-expense method that applies to the return, preserve the required travel substantiation, and keep lodging documentation separately when lodging is claimed.03 · Deadlines

|---|---|
| January 1–September 30, 2026 | Use the $80 CONUS / $86 OCONUS special transportation rate only where Notice 2025-54 and the underlying eligibility rules apply |
| Each departure or return day | Apply a permitted partial-day proration method; three-fourths of the applicable rate is one method allowed by Rev. Proc. 2019-48 |
| During the year | Reconcile trip dates, travel location, tax-home status, HOS qualification, employer reimbursements where relevant, and any days that should be excluded |
| Before October 1, 2026 travel is calculated | Check the latest IRS annual special-per-diem notice rather than automatically carrying forward $80/$86 |
| Before filing the 2026 return | Reconcile the trip log to the method used on the return and flag any disputed tax-home, reimbursement, or qualification issue for review |

How to Claim It: Records and Source Checks
Methodology & Sourcing
Per diem is a substantiation method for qualifying expenses. It is not a substitute for proving that qualifying business travel occurred. Rev. Proc. 2019-48 requires the taxpayer to substantiate the time, place, and business purpose of travel for the day or partial day when using the M&IE method. A practical trucker per-diem file should therefore connect the calculation to the trip itself. That can include the dates, general travel locations, business purpose, whether each day was full or partial, CONUS or OCONUS treatment, HOS qualification where relevant, reimbursement information, and records supporting travel away from the tax home. ELD, dispatch, settlement, load, fuel, or lodging records may help establish those facts. This article does not treat any one of those records as a universal IRS-mandated document for the deduction.IRS Notice 2025-54

Per diem is easier to review when four questions are kept separate: Did the travel qualify? Which M&IE rate applies? Which meal percentage applies? What records support the trip? Once those questions are separated, the calculation becomes easier to follow and easier to explain. Knowing that the published CONUS rate is $80 still does not complete the tax analysis. The trip may not meet the away-from-tax-home rules. A departure or return day may require partial-day treatment. The 80% meal limitation may or may not apply. And a W-2 reimbursement may need to be reviewed under the employer’s reimbursement arrangement rather than treated as the driver’s own Schedule C deduction. The objective is not to find the largest daily figure. It is to arrive at a calculation that matches the driver’s actual travel, records, and filing position.Truck Driver Per Diem FAQs
For qualifying transportation-industry travel, the IRS special M&IE rate currently published for October 1, 2025 through September 30, 2026 is $80 per day within CONUS and $86 per day outside CONUS. Those amounts are the special meal and incidental expense rates, not guaranteed deductions and not flat lodging allowances. Before using them, confirm that the taxpayer, trip, tax-home facts, and method qualify. For travel beginning October 1, 2026 or later, check the IRS notice applicable to that later period rather than automatically carrying $80/$86 forward.
The special transportation-industry method applies to qualifying transportation workers. Rev. Proc. 2019-48 defines transportation-industry work for this purpose as work directly involving the movement of people or goods by specified transportation modes - including truck - and regularly involving travel away from home with stops during a single trip at localities that have differing federal M&IE rates. The taxpayer must also satisfy the underlying business-travel rules. Being a truck driver, holding a CDL, or driving interstate does not by itself establish every requirement.
Because two separate rules are being combined. The current CONUS transportation-industry M&IE rate is $80. For qualifying business meals of an individual subject to DOT hours-of-service limits, the meals deduction percentage may be 80%. For a qualifying full day, $80 × 80% equals $64. That does not make $64 the IRS per-diem rate. It is the result of applying the relevant meals percentage to the $80 M&IE amount.
A typical W-2 company driver generally cannot claim ordinary unreimbursed employee travel expenses as a miscellaneous itemized deduction. Current IRS guidance for 2026 explains that this disallowance was made permanent, with limited statutory exceptions. Employer reimbursement is a separate question. A company may pay qualifying travel allowances under an accountable plan, and the treatment depends on the plan, substantiation, reimbursement amount, and whether excess amounts are properly handled.
For a self-employed taxpayer using the M&IE deduction method under Rev. Proc. 2019-48, three-fourths of the applicable M&IE rate is one permitted way to prorate a partial travel day. The revenue procedure also allows another proration method if it is consistently applied and consistent with reasonable business practice. Using the three-fourths method at an $80 CONUS rate produces $60 before applying the appropriate meal-expense limitation. The trip must still qualify as business travel away from the taxpayer’s tax home.
Keep enough information to establish the time, place, and business purpose of the travel, together with the facts needed to support the calculation. Rev. Proc. 2019-48 specifically requires time, place, and business-purpose substantiation when the M&IE method is used. Depending on the driver’s facts, useful records can include trip and dispatch records, ELD information, carrier settlements, load records, fuel activity, lodging records, reimbursement statements, and a schedule identifying full and partial travel days. Those records support the facts; the tax rules determine whether and how the amount is deductible.
