Tax and Accounting for Trucking and Owner-Operators

Most of what a general accountant knows about small business tax applies to trucking. The parts that do not are the parts that matter, and they are worth several thousand dollars a year to an owner-operator who claims them and nothing to one who does not.

The meal deduction is the clearest example. Business meals are ordinarily deductible at half their cost. Drivers subject to Department of Transportation hours-of-service rules are allowed a higher proportion, and the deduction can be claimed per day away from home rather than receipt by receipt. Over a year of running, that difference is not marginal.

Then there are the filings nobody else has. The federal heavy vehicle use tax is its own annual return, due on its own schedule, for vehicles at or above a weight threshold. Fuel tax is reported quarterly through the International Fuel Tax Agreement, apportioned across every jurisdiction the truck actually drove through — which means the mileage and fuel records are a tax document, not paperwork.

And the truck itself is the largest single deduction decision most owner-operators ever make. Expensing it, depreciating it, or splitting the difference changes the tax bill for years, and the right answer depends on what the next three years look like rather than this one.

Two failures account for most of what we see. The first is no records at all — a shoebox, a bank statement and a hope. Per diem needs days away from home, fuel tax needs miles by state, and neither can be invented after the fact.

The second is quarterly estimates set from last year when this year looks nothing like it. Freight rates move, and a driver who had a strong year and a weak one back to back is either overpaying all year or facing a bill they did not plan for. Estimates should be revised during the year, not copied forward.
