A log book is a written record of your business use of a motor vehicle over a period of time. Log books must be recorded in English and must be made at the end of the journey or as soon as possible afterwards.

Log books must be kept for 12 consecutive weeks in the first year that you claim a deduction for the motor vehicle and every fifth year thereafter. It is illegal to backdate a log book.

The ATO can tell if you have backdated a log book as there is a unique code printed in the log book.

This unique code is located on the interior of the spine on the last page of the book facing the inside back cover.

Example of a log book:
