Maintaining a logbook can be an essential part of managing your tax obligations, especially if you use your personal vehicle for work-related purposes. As an accountant, I regularly advise clients on the importance of keeping a logbook and the specific records required to meet the Australian Taxation Office (ATO) standards. Here’s what you need to know about maintaining a logbook for tax purposes.

1. What is a Logbook?

  • Purpose of a Logbook: A logbook is a record that details the use of your vehicle. It’s used to determine the percentage of vehicle use that is work-related, which in turn affects your claimable expenses on your tax return.
  • Validity Period: Once completed, a logbook is valid for five years, unless there are significant changes in your work-related vehicle use.

2. Starting a Logbook

  • 12 Consecutive Weeks: The ATO requires that your logbook is kept for a minimum continuous period of 12 weeks. This period needs to be representative of your usual travel throughout the year.
  • Beginning Date: You can start your logbook at any time, but it must cover a period when the car is being used for its typical pattern of business use.

3. Information to Record in a Logbook

  • Dates of Travel: Record the start and end dates of the logbook period.
  • Odometer Readings: Note the vehicle’s odometer readings at the start and end of the 12-week period.
  • Each Journey: For each journey, record the date, odometer readings at the start and end, total kilometers traveled, and the reason for the trip (e.g., meeting with a client).
  • Business vs Personal Use: Distinguish between business and personal use.

4. Calculating Business Use Percentage

  • Percentage Calculation: At the end of the 12-week period, calculate the percentage of car use that is for business purposes. This percentage is then applied to car expenses to determine your claimable amount.
  • Expenses Include: Car expenses include fuel, servicing, insurance, interest on loans, depreciation, and lease payments.

5. Importance of Accurate Records

  • ATO Compliance: Accurate logbook records are essential for ATO compliance. Inaccurate or incomplete logbooks can lead to disallowed claims and potential penalties.
  • Record Keeping: Keep your logbook, along with all receipts and records related to car expenses, for five years from the date of your tax return.

6. Using Logbook Apps

  • Digital Logbooks: There are several logbook apps available that can simplify the record-keeping process. These apps can automatically track your trips and calculate your business use percentage.

Maintaining a logbook is a crucial practice for anyone using a personal vehicle for work-related purposes in Australia.

Remember, keeping accurate and detailed records is key to simplifying your tax affairs and maximising your eligible deductions.
