Quarterly Trucking Bookkeeping Checklist

Quarterly tasks

• Run profit and loss report for the quarter
• Compare year-to-date net profit to prior year
• Review quarterly tax reserve and adjust if needed
• Compile IFTA mileage and fuel records for the quarter
• Check Form 2290 calendar for any first-used-month filings due
• Back up receipts, statements, and ELD exports to a durable storage location

Running the profit and loss

Pull the quarterly P&L from your bookkeeping software or spreadsheet. Review each major category — fuel, repairs, insurance, tolls, dispatch fees — against the prior quarter and prior year to spot anything that looks out of place. A repair cost five times higher than normal might be a major engine repair that's correctly categorized, or it might be a personal expense that ran through the business account. Catch these discrepancies at the quarter, not at year-end when the amounts are larger and memories are fuzzier.

Estimated tax planning

Quarterly estimated tax payments are generally due in mid-April, mid-June, mid-September, and mid-January. The quarterly bookkeeping review gives you the profit figure you need to decide how much to pay. Compare year-to-date net profit against your prior-year tax liability — if you're running ahead of last year, the current quarter's payment may need to be higher than the safe harbor installment. If profit is down significantly, paying the exact safe harbor amount may be more cash-efficient than overpaying. Your tax preparer can advise on the right amount given your current-year facts.

IFTA quarterly records

IFTA quarterly returns require per-jurisdiction mileage and per-jurisdiction fuel purchase totals for the quarter. At quarter-end, pull the mileage log (or ELD per-state export) and the fuel receipt tracker, total each by jurisdiction, and confirm the numbers are complete before the filing due date. IFTA quarterly returns are typically due April 30, July 31, October 31, and January 31 — verify current due dates with your base jurisdiction, as extensions can apply in some circumstances. Filing late or with incorrect jurisdiction totals can trigger an audit or penalty.

Equipment and asset documentation

If you purchased, sold, or traded a truck or trailer during the quarter, document the transaction now rather than waiting for year-end. For a purchase: date, price, any trade-in value, and how it was financed. For a sale: date, sale price, and buyer. These items affect depreciation calculations, potential Section 179 expensing, and gain or loss on sale — all of which your preparer needs well before filing. Keeping a simple asset log updated quarterly makes year-end significantly easier.

Backing up records

At quarter-end, back up all digital records to at least one additional location — a cloud drive, an external hard drive, or both. Fuel card exports, carrier settlement CSVs, ELD mileage reports, and scanned receipts are hard to replace if a computer fails or a portal purges its history. A quarterly backup routine means you're never more than three months behind on disaster recovery.
