Common FBT Mistakes Business Owners Should Avoid
12 March 2026

Fringe Benefits Tax (FBT) is one of those areas where even well‑run businesses can slip up. The rules are detailed, the reporting periods are unusual, and small misunderstandings can quickly turn into compliance issues or unexpected tax bills. Recent reviews of common FBT practices show that many business owners are still relying on outdated assumptions or incomplete advice. A clear understanding of the rules and keeping strong documentation can make all the difference.
1. Mixing up the FBT year and the financial year
The FBT year runs from 1 April to 31 March, not 1 July to 30 June. Using the financial year instead can lead to incorrect calculations, missed lodgements, and potential penalties.
2. Assuming all work vehicles are automatically exempt
Many businesses believe that utes, vans, and other commercial vehicles are always FBT‑exempt. They’re not. The exemption only applies when private use is strictly limited, typically to:
- Home‑to‑work travel
- Incidental personal use
- Minor, infrequent private trips
If an employee or associate uses the vehicle for school runs, weekend trips, or other significant personal purposes, the exemption may no longer apply.
3. Incomplete or incorrect record‑keeping
FBT is documentation‑heavy, and the ATO expects evidence.
Key requirements include:
- A 12‑week logbook reflecting normal usage when using the logbook method (for each employee and for each vehicle)
- Employee declarations confirming how vehicles or benefits were used
- Consistent, accurate and contemporaneous records
Without proper documentation, the ATO may reject preferred valuation methods and apply higher taxable values.
4. Missing recent regulatory changes
FBT rules evolve, and businesses need to stay informed.
A major upcoming change is that plug‑in hybrid electric vehicles will lose their FBT exemption from 1 April 2025.
Businesses providing these vehicles should review salary packaging arrangements and cost assumptions well before the deadline.
5. Incorrect valuation and reporting of benefits
The taxable value of fringe benefits must be grossed‑up when reported. Additionally, employee contributions when properly documented can reduce or eliminate the FBT liability.
Incorrect valuations or missing contribution records can inflate your FBT bill unnecessarily.
***Practical Steps for Business Owners
To reduce FBT risk and stay compliant, consider the following simple practices:
- Use the correct FBT year (1 April – 31 March) for all calculations
- Review vehicle policies to ensure private use meets exemption criteria
- Maintain accurate logbooks, declarations, and supporting documents
- Stay across regulatory changes, including the EV exemption adjustments
- Record employee contributions and benefit valuations correctly
Regular reviewing your FBT arrangements and seeking timely professional advice when needed can also help you avoid costly corrections and keep your FBT position optimised.
