The expenses you track — or don't — decide your tax bill, your IFTA filing, and whether you actually know your profit. This guide covers what to log and how to stay on top of it without drowning in paper.
The expenses every owner-operator should track
- •Fuel. Your biggest single cost, and the one that feeds both your tax deductions and IFTA.
- •Truck payment or lease. The fixed cost of the truck itself.
- •Insurance. Truck, cargo, and liability premiums.
- •Maintenance, repairs, and tires. Everything that keeps the truck running and legal.
- •Tolls, scales, and parking. Small individually, real money over a year.
- •Permits, licenses, and IFTA. The cost of staying legal to run.
- •ELD, phone, and software. The tools you use to run the business, TruxSheet included.
- •Association dues. Trucking association memberships and similar business costs.
- •Meals and per diem. The daily deduction for nights away from home — easy to miss if you're not tracking it.
- •Supplies. Straps, tools, gear, and other ordinary costs of running your truck.
Why it's worth the effort
Tracking expenses pays off three ways. First, tax deductions — every logged expense with a receipt lowers your taxable income. Second, IFTA — fuel purchases logged by state feed straight into your quarterly filing. Third, and maybe most important, profit — you can't know your true cost per mile, or whether a load actually made you money, without knowing what it cost you to run.
Receipts: your proof
A logged expense without a receipt is a weaker deduction, and fuel receipts specifically back up your IFTA numbers if you're ever audited. Paper receipts fade and get lost in a cab fast — the simplest fix is snapping a photo of each one the moment you get it, so the proof exists before it has a chance to disappear.
How to stay organized all year
Log and categorize each expense as it happens, attach the receipt right then, and keep business spending separate from personal. Reconstructing a full year of expenses at tax time — digging through a shoebox or bank statements — is where deductions and IFTA gallons get missed. Doing it as you go keeps everything clean and ready whenever you need it.
How TruxSheet helps
TruxSheet lets owner-operators log every expense with a receipt photo and category in seconds from their phone — feeding tax prep, IFTA, and your cost-per-mile automatically as you go. Your records stay organized all year instead of becoming a project every April.
Frequently asked questions
What expenses should an owner-operator track?
Track every business cost: fuel, truck payment or lease, insurance, maintenance and repairs, tires, tolls and scales, parking, permits and licenses, IFTA, ELD and phone, software subscriptions, association dues, and meals/per diem while away. If it's a cost of running your truck, log it.
Why does tracking expenses matter?
Three reasons: tax deductions (every logged expense with a receipt lowers your taxable income), IFTA (fuel by state feeds your quarterly filing), and profit (you can't know your cost per mile or whether you're making money without knowing your costs).
Do I need to keep receipts?
Yes. Receipts are what back up your deductions if you're ever audited, and fuel receipts are needed for IFTA. The easiest approach is to snap a photo of each receipt when you get it, so nothing gets lost in the cab or your wallet.
How should I organize my expenses?
Categorize each expense as you log it (fuel, maintenance, insurance, and so on) and attach the receipt. Logging as you go — rather than sorting a year's worth at tax time — keeps everything clean and makes tax prep and IFTA fast.
What's the easiest way to track expenses on the road?
An app on your phone that lets you log an expense and snap the receipt in a few seconds, wherever you are. That beats saving paper receipts that fade or get lost, and it means your records are ready whenever you need them.
