Bookkeeping advice written for coffee shops doesn't survive contact with a truck. A café's books never get audited by a fuel-tax agreement, don't care about miles, and aren't kept by someone who just drove eleven hours. Trucking books have three extra masters — IFTA, the IRS's per-diem and depreciation rules, and your own cost per mile — and the system below is shaped by all three.
Why trucking books are different
Three reasons a generic ledger isn't enough:
- Miles are a second currency. Every dollar means something different depending on the miles behind it. Books that don't track miles can tell you what you spent, but never what a mile costs or what a load cleared — the two numbers that actually run the business. The cost-per-mile guide is the whole argument.
- IFTA is bookkeeping law. Fuel receipts and distance records by state, kept four years, auditable. Your books and your IFTA records are the same records, or you're keeping two sets badly.
- Trucking has its own tax terrain. Per diem, truck depreciation, Form 2290, quarterly estimated payments — each one rewards clean records and punishes shoeboxes. The deductions guide covers what's on the table.
Set up once: the separations
Ninety percent of bookkeeping pain is mixing things that should never touch. Separate them once and the weekly work almost does itself:
- A business checking account and card. Every settlement lands there; every business expense leaves from there. The bank statement becomes a rough draft of your books instead of a puzzle. Personal groceries on the business card is the single habit that turns tax season into archaeology.
- A tax set-aside. Move a fixed percentage of every settlement into a separate account the day it lands, before it feels like yours. The set-aside guide covers how much.
- A maintenance reserve. Tires and overhauls are expenses you haven't dated yet. Accrue them per mile now or borrow from next year later.
The five categories that matter
You don't need forty ledger accounts. You need five that are always current:
| Category | What goes in it |
|---|---|
| Revenue, by load | Every load with its rate, its miles (loaded and empty), broker, and settlement date. This is what makes rate-per-mile and per-load profit computable. |
| Fuel | Every stop: date, state, gallons, price, total. Doubles as your IFTA fuel record — which is why it gets its own bucket instead of hiding in "expenses." |
| Fixed bills | Truck and trailer payments, insurance, plates and permits, ELD, phone, parking — the monthly bills that don't care whether you drove. |
| Maintenance & repairs | Everything that keeps the truck alive, tires included — tagged to the truck if you run more than one. |
| Everything else | Tolls, scales, lumpers, washouts, lodging, supplies. Small lines, but they're real cost per mile too. |
Five categories, plus miles, is enough to produce a P&L, your cost per mile, your IFTA return, and your tax preparer's whole wish list. Anything fancier is optional.
The ten-minute weekly rhythm
Books die from batching. "I'll catch up Sunday" becomes "I'll catch up at quarter-end" becomes a February of misery. The alternative is a rhythm small enough to survive a work week:
- When you book a load — enter it: rate, miles, broker. Ten seconds, and your revenue record is done before the truck moves.
- At the pump — capture the receipt before pulling away. Photo or app, doesn't matter, as long as it's the same place every time.
- Each driving day — log the day's miles, loaded and empty. This is the record that feeds cost per mile and IFTA at once.
- Friday, ten minutes — match the week's settlements against loads, sweep stray receipts into their categories, glance at the week's rate per mile. Done.
Sit days count. A week the truck didn't move still gets logged — zero miles is data, and it's the data that makes your cost per mile true. Books that skip the bad weeks flatter you right up until the bank account disagrees.
See what the records buy you
The point of the rhythm is the numbers it feeds: your cost per mile, your required rate, and a straight answer on every load offer. All three calculators are free — the records are what make them yours.
Work out your cost per mileThe quarterly calendar
Four dates rule a trucking year, four times: IFTA returns are due the last day of the month after each quarter — April 30, July 31, October 31, January 31 — and federal estimated-tax payments run their own quarterly schedule a couple of weeks earlier. Add the annual pair: Form 2290 by August 31 for most trucks, and plates/IRP on your state's cycle.
If the weekly rhythm is alive, quarter-end is arithmetic, not archaeology: the fuel bucket and the mileage log are the IFTA return's inputs, and the P&L is what your estimated payment gets based on. The set-aside guide has the current payment dates and the safe-harbor rule that prevents penalties.
What your tax preparer actually needs
Hand a trucking-literate preparer these and you're a cheap client; make them dig and you're an expensive one:
- A P&L: revenue and the five expense categories, by year.
- Total miles and nights away from home (per diem lives on that second number).
- What you paid for the truck and trailer, and when — depreciation needs dates and amounts.
- The 1099s from brokers and factoring, matched against your own revenue record — yours is the audit trail when a 1099 is wrong.
- Receipts, organized enough to find one on request. The receipts guide covers the how and the how-long.
When the spreadsheet stops working
A spreadsheet and four bank accounts genuinely can run one truck — plenty of good operators do it. The spreadsheet fails at the same three places for everyone: receipts pile up unscanned, daily miles stop getting logged, and nothing cross-checks settlements against what was booked. If those three are holding, keep the spreadsheet. When they slip — and they slip at midnight in a truck stop, not at a desk — that's what software is for: not harder math, just data entry that happens at the pump instead of in February.
