If you drive a truck for a living, your tax return has more moving parts than most. Per diem days, fuel for IFTA, scale tickets, tolls, repairs, parking, lumper fees, washouts, ELDs, ATA dues, satellite radio, motel rooms when you cannot legally drive another mile. Owner-operators carry tens of thousands of dollars in deductible expenses through a year, and the difference between a clean return and a sloppy one can be five figures.

The catch is that the receipts these deductions depend on live in a diesel-stained cab. They get jammed in a glove box, fade in the sun on the dash, get rained on at a fuel island, or just disappear between the cushions. By tax time you have a shoebox of thermal paper that is half illegible and an accountant who is going to charge you for the privilege of sorting it.

This guide is about which receipts you actually need to keep, what the IRS expects them to show, and how to capture them in a way that survives the road.

Per diem — the biggest deduction most drivers underestimate

For 2025, the IRS allows OTR drivers subject to DOT hours-of-service regulations to deduct 80% of the special transportation worker per diem rate, which has been $69 per day for travel within the continental U.S. (the rate is set by the IRS and the GSA and updates periodically — check IRS Publication 463 and Notice 2024-68 for the year you are filing). That works out to a meaningful deduction over a year on the road: a driver out 250 days a year can deduct in the neighborhood of $13,800 just from per diem before any other expense.

Per diem does not require you to keep meal receipts. It is a standard daily rate. What it requires is proof you were on the road that day. The IRS expects three things for a per diem day to count:

Half-days count as half-days. The day you leave home and the day you return are usually 75% of the full rate. Your accountant or tax software will handle the math — what you need to give them is the count of full days and partial days, backed by your logs.

Fuel: the IFTA receipt that doubles as a tax record

You already keep fuel receipts for IFTA quarterly reporting. The good news is the same records satisfy the IRS for the federal fuel deduction. The bad news is that thermal paper fades, fuel-island receipts run small and cramped, and IFTA wants specific information.

Every fuel purchase needs to show the date, the location (city and state, not just the truck stop name), the number of gallons, the price per gallon, and the total. Most modern fuel cards print all of that — some older pumps do not, in which case the IFTA reporting fields you fill in at the pump are the record.

For tax purposes, the fuel itself is fully deductible if you use the actual-expense method. Owner-operators generally cannot use the standard mileage rate (it is not available for vehicles you use for hire), so actual-expense is the path. That means every gallon you buy needs a receipt. The IRS does not love “I estimate I bought 12,000 gallons.”

The other reason to keep fuel receipts even when your fuel card has all the data: the card statement is a summary, not a record. If you ever get audited, the auditor wants to see the underlying receipts, not just the card’s monthly report. Same principle for any expense.

The non-obvious receipts that add up

The big-line-item deductions — per diem, fuel, truck payment, insurance — everyone tracks. The deductions that get missed are the small recurring ones that nobody bothers to record because each one feels too trivial to matter. Across 250 days on the road, they add up to thousands.

None of these requires a receipt that is fancy or printed on good paper. What they require is a record that shows the date, the vendor, the amount, and a note about what it was for. A photo of a thermal paper receipt taken at the moment of purchase is as good a record as any.

How to capture receipts from a cab

This is where most systems break down for drivers. The advice that works for a freelance designer at a desk — “just scan it when you get home” — falls apart for someone whose home is 2,000 miles away and who already has a stack of 30 receipts in the cab.

The system that survives the road has three properties:

  1. Capture happens at the moment of payment. If you wait until you stop for the night, half the receipts will be lost, faded, or forgotten.
  2. It does not require both hands or full attention. You are leaving a fuel island, you have a shipper waiting, you cannot stop to log into an app and fill out a form.
  3. The original receipt does not need to survive. Once the photo is captured, the thermal paper can fade to nothing — you have a digital record that the IRS accepts.

The simplest workflow that meets all three: a one-tap camera button on your phone’s home screen that uploads to your books automatically. You pay, walk to the cab, snap the receipt before climbing in, throw it in the cup holder or trash. The capture itself takes longer to describe than to do. Across 250 days on the road that is the difference between a year of clean books and a year of guessing.

SendToBooks gives you three ways to do this, and which one you use depends on the day:

Categorizing as you go vs. categorizing at year-end

The other thing that distinguishes a clean trucker tax return from a messy one is whether the receipts are categorized at all. A pile of 600 receipts with no labels is barely better than nothing — your accountant still has to sort each one, and they will charge you for the time.

SendToBooks tries to figure out the category from the receipt itself (a fuel receipt at a Pilot is fuel; a Walmart receipt for batteries and oil is maintenance; a motel receipt is lodging), and you confirm or correct it in the dashboard. Set up books for each truck if you run more than one, and category lists that match your trucker tax forms — Fuel, Maintenance & Repairs, Tolls & Scales, Insurance, Communications, Dues & Subs, Per Diem Days, Lodging, Other.

At year-end you export the lot. Your accountant gets a clean spreadsheet of categorized expenses with the underlying receipt images attached. The conversation goes from “what is this charge?” to “here is how much you deducted in fuel, here is your per diem days count, here is your IFTA gallons summary.”

What audit-proofing actually means

The IRS does not audit every trucker. But when they do, the audits are deep — transportation is a sector with a lot of cash and a lot of opportunity to under-document. The audit-resistance kit is not complicated:

None of that is unreasonable. It just requires a system where capture is so easy you never skip it. The shoebox is not that system.

Stop losing receipts in the cab.

One tap from your phone’s home screen. Every fuel stop, every scale, every meal — captured the moment you pay, organized by the time you reach the bunk.
