For auto transport operators, expense tracking is not optional bookkeeping — it is the difference between knowing your true cost-per-load and guessing at it. Every fuel fill, every permit fee, every tire replaced on the side of I-70 affects your margin on that run. When those costs are tracked consistently, you can price confidently, spot problem routes, and survive a CRA or IRS audit without scrambling through a shoebox of receipts.
The short answer to what to log: every dollar that leaves your business to move vehicles. That means fuel, driver pay, maintenance, insurance, permits, tolls, and depreciation — all categorized by load, by truck, and by date. The sections below break down each category with the specifics operators in both the US and Canada need to stay compliant and profitable.
Fuel: Your Largest Variable Cost
Fuel typically accounts for 35–45% of operating costs on a loaded car hauler run. Logging it correctly matters for two reasons: margin analysis and tax compliance.
Every fuel purchase should capture the date, location (state or province), gallons or litres purchased, total cost, and the truck it was purchased for. This is the raw data that feeds your cost-per-mile or cost-per-kilometre calculation and — critically — your IFTA filing.
US operators filing quarterly IFTA returns need miles driven and gallons purchased broken down by jurisdiction. Miss a jurisdiction or misattribute a fill-up and you will owe interest and penalties. Canadian operators face the same IFTA requirement across participating provinces and territories; if you run into the US, you are filing in both countries. See our IFTA compliance guide for Canadian auto haulers for a step-by-step breakdown.
Fuel cards (WEX, Comdata, CFN) simplify this by generating per-transaction reports you can import directly. If your drivers pay cash or use a personal card and get reimbursed, you need a strict receipt-submission policy — paper receipts fade and disappear.
Driver Pay and Contractor Payments
Whether your drivers are employees (T4 in Canada, W-2 in the US) or independent contractors (T4A / 1099), every payment needs to be logged against the load it covers. This matters for load-level profitability: a run that grosses $1,800 but costs $950 in driver pay, $300 in fuel, and $120 in permits leaves you $430 — before truck costs. You cannot see that number unless driver pay is tied to the load.
For Canadian operators, the CRA distinguishes sharply between employees and contractors. Misclassification triggers retroactive CPP/EI assessments with interest. Log the classification for each driver, keep signed contractor agreements on file, and record every payment date and amount.
For US operators, FMCSA and DOT compliance audits may review driver pay records as part of hours-of-service and driver qualification file checks. Keeping pay records organized by driver and date-range reduces audit friction significantly.
Maintenance and Repairs
A breakdown on an interstate is not just a repair bill — it is a late delivery, a frustrated broker, and possibly a cargo claim. Tracking maintenance costs per truck helps you identify which units are becoming liabilities before they cost you a load.
What to log for every maintenance event
- Date and odometer reading (miles or kilometres)
- Truck unit number or VIN
- Description of work performed
- Parts cost and labour cost (separate line items)
- Vendor name and invoice number
- Whether the repair was preventive or breakdown-driven
Preventive maintenance — oil changes, brake inspections, tire rotations — is deductible in both the US and Canada and should be tracked separately from unplanned repairs. This separation helps with tax categorization and with spotting trucks that are generating abnormally high unplanned repair costs.
Canadian operators: CVOR (Commercial Vehicle Operator's Registration) in Ontario and equivalent NSC safety fitness requirements in other provinces require documented maintenance records. An incomplete maintenance log during a carrier audit is a violation that can affect your safety rating. Treat these records as compliance documents, not just accounting entries.
Permits, Licensing, and Regulatory Fees
Auto transport involves a recurring stream of permit and licensing costs that are easy to miss in the books because they arrive irregularly. Missing them understates your true operating cost.
| Expense | US | Canada | Frequency |
|---|---|---|---|
| Operating authority / carrier licence | FMCSA MC number / DOT number | NSC carrier profile registration | Annual or biennial renewal |
| IFTA licence and decals | Base jurisdiction filing | Base province filing | Annual |
| IRP (apportioned plates) | Yes — all jurisdictions | Yes — all jurisdictions | Annual |
| Oversize / overweight permits | State-by-state, per-trip or annual | Province-by-province | Per trip or annual |
| Vehicle registration (per truck) | State DMV | Provincial MTO / SGI / ICBC etc. | Annual |
| CVOR / safety fitness certificate | N/A | Provincial — required in ON, BC, AB, etc. | Varies by province |
Log each of these against the truck it covers and set a renewal reminder. A lapsed IFTA licence or expired IRP plate can ground a truck until resolved — a cost that is invisible in your books unless you are tracking compliance expiries alongside financials.
Insurance
Commercial auto transport insurance — primary liability, cargo, physical damage, and bobtail — is one of the largest fixed costs in the business, often ranging from $15,000 to $40,000+ CAD or USD annually per truck depending on coverage, history, and jurisdiction. It should be logged as a monthly or per-policy-period expense allocated to each covered unit.
When you add or remove a truck mid-year, the insurance premium adjusts. Log the adjustment date and the revised amount so your cost-per-truck numbers stay accurate. If you carry cargo insurance with a per-load or per-vehicle sublimit, note that in your load records — it affects how you price loads carrying high-value vehicles.
Tolls, Scales, and Incidental Road Costs
These are small individually but add up over a quarter. A truck running the I-95 corridor between Florida and New England can easily accumulate $300–$600 in toll costs per round trip. Weigh station fees, border crossing fees (for cross-border US/Canada runs), and parking at terminals or auction lots all belong in your books.
The most reliable way to capture these is to require drivers to log every incidental expense in real time — either through a fleet management app or a standardized daily expense form. Waiting until the end of the week means small items get forgotten.
Compared to tracking this in a spreadsheet, a connected fleet management platform can capture toll data automatically from E-ZPass or highway transponder accounts and flag missing entries before the quarter closes. See how AutoHauler AI compares to managing expenses in spreadsheets.
How to Structure Your Expense Categories
Your chart of accounts for auto transport should map to how your accountant (and the CRA or IRS) expects to see costs reported. A practical structure for most small-to-mid-size carriers:
- Fuel & Oil — diesel, DEF, oil changes (separate from major maintenance)
- Driver Labour — employee wages, contractor payments, per-diem
- Truck Maintenance & Repairs — parts, labour, tires
- Insurance — liability, cargo, physical damage (per truck)
- Permits & Licensing — IFTA, IRP, oversize permits, carrier fees
- Tolls & Road Fees — highway tolls, weigh station fees, border fees
- Depreciation — capital cost allowance (CCA) in Canada; MACRS in the US
- Communications & Software — dispatch software, ELD subscription, cell plans
- Administrative — accounting, legal, office
Running these categories consistently quarter over quarter gives you a clear picture of where your cost base is moving. A sudden jump in the Truck Maintenance line for a specific unit is a signal worth investigating before that unit becomes a larger liability.

Putting It Together: Cost Per Load
The goal of all this tracking is a number most carriers never actually calculate: true cost per load. Take a specific load, assign the fuel burned on that run, the pro-rated driver pay, the proportional share of insurance and permits for that truck for that day, any tolls or permits specific to the route, and any maintenance that occurred. Subtract from gross revenue. That is your actual margin.
Most carriers who do this calculation for the first time discover their worst-margin loads are not the short runs they assumed — they are the long-distance, high-fuel runs that look big on gross revenue but have costs to match. Knowing this changes how you bid and which lanes you prioritize.
