Keeping Odometer Readings for Fringe Benefits Tax (FBT)– 31 March 2025


Why Odometer Readings Are Important for FBT

The Australian Fringe Benefits Tax (FBT) year runs from 1 April to 31 March, and one of the key compliance requirements for employers providing motor vehicles to employees is recording odometer readings on 31 March each year. These readings help determine the taxable value of car fringe benefits and ensure accurate FBT calculations.


How Odometer Readings Affect FBT

The Australian Taxation Office (ATO) uses odometer readings in various FBT calculation methods, including:

  • Operating Cost Method: Odometer readings help establish the proportion of private versus business use. More accurate records can lead to lower FBT liability if business use is high.
  • Statutory Formula Method: While this method applies a set percentage to the car’s base value, maintaining odometer readings ensures accurate reporting and compliance.
  • Logbook Records: If you use the operating cost method, odometer readings must match logbook entries to validate the business use percentage.


Steps to Record Odometer Readings on 31 March 2025

To stay compliant and avoid penalties, follow these steps:

  1. Check Each Vehicle: Ensure all company and trust vehicles have their odometer readings recorded at the end of the FBT year.
  2. Record the Reading Accurately: Use a logbook, spreadsheet, or digital system to document each vehicle’s mileage.
  3. Note the Date and Vehicle Details: Include the date (31 March 2025), vehicle make and model, registration number, and the odometer reading.
  4. Maintain Proper Records: Keep these records for at least five years in case of an ATO audit.
  5. Report in FBT Calculations: Use the readings to determine FBT liability and ensure accurate declarations in your FBT return.


Consequences of Not Keeping Odometer Records

Failing to maintain odometer readings can lead to:

  • Higher FBT Liabilities: Without proper records, the ATO may default to higher taxable amounts.
  • Increased Scrutiny from the ATO: Poor record-keeping raises the risk of audits and penalties.
  • Difficulty Justifying Business Use Percentage: If using the operating cost method, missing odometer readings may invalidate logbook entries, reducing tax deductions.


Next Steps

Accurate odometer readings on 31 March 2025 are essential for businesses providing vehicles to employees. By maintaining proper records, employers can minimise FBT liabilities, ensure compliance with the ATO, and avoid unnecessary penalties. Take the time today to record all company vehicle odometer readings and store them securely for future reference.

Monthly GST Reporting for Small Businesses
By Liz Gibbs March 25, 2025
From 1 April 2025, the ATO will be moving around 3,500 small businesses from quarterly to monthly GST reporting where they have a history of: ❌ non-payment; ❌ late or non-lodgment; or ❌ incorrect reporting. Once the change is implemented, it will remain in place for a minimum of 12 months. Affected small businesses and their tax agents will be contacted by the ATO when their GST reporting cycle is changed. A review process is available for those who don’t believe they have a history of poor compliance and should be able to remain on their current GST reporting cycle. The ATO believes that this will help small businesses improve compliance with their GST obligations and build good business habits. Do you think this is a good move?
