Bookkeeping for Trucking Companies

Trucking is one of the few small businesses where the bookkeeping has a regulator reading over its shoulder. IFTA wants miles and gallons by state every quarter. The heavy vehicle use tax wants a filing per truck. Insurance auditors want payroll and mileage classifications. A bookkeeper who only tracks dollars leaves you rebuilding all of that from fuel card exports and ELD reports every quarter.

The economics are unusual too. Revenue arrives per load, costs accrue per mile, and the margin between them is thin enough that a few cents of untracked cost per mile decides whether the year was worth it. Add factoring (cash arrives net of fees, days after the revenue was earned) and owner-operator settlements (payments that are part contractor expense, part expense recovery), and the transaction flow simply does not fit a template chart of accounts.

We build trucking books to serve three masters at once: the compliance calendar, the dispatch decisions, and the tax return. The same structure that makes the IFTA quarter painless also makes the per-mile numbers real and the year-end handoff to trucking tax planning clean.

These are representative accounts we set up for carrier clients, beyond the standard operating accounts every business needs:

The pattern behind every row: if a number has to be reported to someone (IFTA, insurers, the IRS) or used in a decision (rates, replacement, driver pay), it gets its own account instead of dying inside a catch-all.

IFTA, the International Fuel Tax Agreement, covers qualified motor vehicles: generally power units over 26,000 pounds gross vehicle weight, units with three or more axles regardless of weight, or combinations over 26,000 pounds, operating in more than one member state or province. Instead of filing fuel tax in every state you cross, you file one quarterly return with your base state, reporting miles traveled and fuel purchased in each jurisdiction, and the states settle up among themselves.

Returns are due April 30, July 31, October 31, and January 31, and a return is due even for an idle quarter. The filing itself is simple arithmetic when the underlying data exists: fuel receipts coded by state as they post (fuel card feeds make this nearly automatic) and mileage by jurisdiction pulled from the ELD. Our monthly process reconciles gallons to dollars and miles to routes as we close each month, so quarter-end is an export, not an excavation.

Related but separate: the federal heavy highway vehicle use tax (Form 2290) applies to trucks at 55,000 pounds taxable gross weight and up, filed annually for the July-through-June period, generally due by August 31. Clean unit records make that filing, and the state registration renewals that depend on it, a checklist item instead of a scramble.

Every monthly package we deliver for a trucking client is built around unit economics, not just statements. The KPIs we compute and track:

Where a $1.75 Cost Per Mile Comes From (Illustrative)

Illustrative round numbers for a single truck. Your books should produce this bar for your fleet every month; a rate sheet only makes money when it clears your real cost per mile.

The costing model splits fixed costs (payments, insurance, permits, base plates) from variable costs (fuel, driver pay, maintenance, tolls), because the two behave differently when miles change. That split is what tells you whether slow-season freight at a weak rate still beats parking the truck: below variable cost, park it; above variable cost but below total, it depends, and now you have the numbers to decide instead of a feeling.

Company drivers are payroll: wages, withholding, employer payroll taxes, workers' comp classifications. Owner-operators are contractors paid through settlements: gross linehaul or percentage, minus fuel advances, insurance charge-backs, trailer rent, and escrow holdbacks, with the net hitting their bank and the gross belonging on their 1099. A settlement recorded as one lump payment destroys both sides of that detail, and year-end 1099s become archaeology.

Our process books each settlement from the settlement statement itself: gross contractor expense, each deduction to its proper account (advances cleared, insurance recovered, escrow held as a liability), and the net tied to the bank transaction. Mixed fleets get both systems running side by side, with payroll integrated into the monthly close.

Per diem is a trucking-specific tax asset the books should support. Drivers subject to DOT hours-of-service rules can use the special transportation-industry per diem for meal costs, and those meal costs are 80% deductible rather than the usual 50%. Capturing nights-away data through the year is what makes the deduction defensible; we set the books up so that number exists in December without reconstructing a logbook.

A trucking balance sheet carries more debt and equipment per revenue dollar than almost any other small business. Every tractor and trailer gets its own fixed-asset record and its own loan schedule, with payments split between interest (deductible) and principal (not). Lenders report a payment; the books need the amortization. Get this wrong and the P&L overstates or understates profit by the principal amount, which is exactly the number a bank or factor will scrutinize on your next credit application.

Depreciation is where clean equipment records pay for themselves. With 100% bonus depreciation permanent for qualified property acquired after January 19, 2025, the timing of a truck purchase is a major tax lever, but only if the books can show basis, in-service dates, and trade-in history per unit. We maintain those schedules monthly so the year-end conversation with the tax side is a decision, not a data hunt. The strategy side of equipment purchases lives on our trucking tax deductions guide.

The engagement runs on a fixed monthly rhythm: bank, fuel card, and factoring accounts reconciled; settlements booked from statements; fuel coded by jurisdiction; equipment and loan schedules updated; and financials (P&L, Balance Sheet, Cash Flow) delivered with the per-mile KPI report by the 20th of the following month. Quarter-end months add the IFTA data package. Year-end adds the tax handoff: depreciation schedules, per diem support, and 1099 data, ready for the return.

The stack is QuickBooks Online at the core, fed by bank and fuel card connections, with dispatch or TMS mileage data and factoring reports integrated into the close. We work with the systems you already run; the goal is one reconciled set of books, not another portal. If your current file needs surgery first, that is a defined catch-up project with its own scope, then the monthly cadence takes over.

Because Taxstra is a tax-led firm, the books are built backward from the return and the planning calendar. The same team that closes your months plans your estimated payments, entity structure, and equipment timing; see bookkeeping for small business for how the general engagement works across industries.

This service is built as a recurring monthly engagement. It fits best when:

• You run one to roughly twenty power units, as a carrier or owner-operator with authority.
• The business generates steady monthly transaction volume: settlements, fuel, loads, and debt payments that need a real close, not an annual cleanup.
• You are subject to IFTA (or about to be) and want the quarterly filing fed by the books instead of assembled from scratch.
• You want per-truck and per-mile numbers you can act on, delivered on a schedule.
• You want bookkeeping and tax planning under one roof, so equipment purchases, entity decisions, and estimated payments are coordinated instead of discovered in April.

It is usually not a fit for a driver leased onto a carrier with no authority, minimal expenses, and a single settlement statement per week; a well-organized annual tax engagement often serves that situation better until the operation grows.
