The logbook must cover a continuous 12-week period and is valid for five years provided your business use percentage does not change significantly.

    What it contains

    12-week (84-day) logbook template with daily trip rows. Each row captures: date, odometer reading at start of trip, odometer reading at end of trip, total km for the trip, destination address, purpose of trip, and classification (business or private). Includes an opening odometer reading page, a weekly summary section, and the final business-use percentage calculation. Also includes instructions for what the ATO requires and common mistakes that invalidate a logbook.

    How to use it

    Choose your 12-week period strategically

    The logbook must run for a continuous 12 weeks (84 days). Pick a period that is representative of your typical driving pattern for the year. Avoid starting during holidays or unusually busy periods unless that is genuinely normal for you. The ATO may reject a logbook that is not representative of your annual pattern.

    Record the opening odometer reading

    On day one, before you drive anywhere, record the odometer reading and the date. This is your starting point. At the end of the income year (30 June), record the closing odometer reading. You need both to calculate total km for the year.

    Log every trip during the 12 weeks

    Record every trip, including private trips. For each trip: write the date, odometer at start, odometer at end, total km, where you went, and whether the trip was for business or private purposes. Round trips count as two entries (outbound and return) unless the entire round trip is for one purpose. The ATO requires EVERY trip to be recorded, not just business trips.

    Calculate your business-use percentage and apply it

    At the end of the 12 weeks, add up total business km and total km. Business-use percentage = (business km / total km) x 100. Apply this percentage to your total actual car expenses for the income year (fuel, insurance, registration, servicing, depreciation, interest on car loan). Keep all expense receipts. The logbook is valid for five years unless your circumstances change significantly.
