FBT Reform: Where Are We At Now?
Double Cab Utes, Perk Vehicles, and the End of the Exemption Era
As outlined in our earlier article, the Government advised in the Budget it intended to proceed with the proposed reforms to Fringe Benefit Tax (FBT), with the most headline-grabbing change being the removal of the work-related vehicle exemption, commonly referred to as the “double cab ute exemption.” These changes are part of a broader FBT overhaul first signalled in Inland Revenue’s consultation paper and later confirmed in the fine print of Budget 2025.
In an interview with Ryan Bridge on The AM Show*, I highlighted the practical implications for employers, particularly fleet owners, tradies, and small business owners, who have long relied on the exemption for vehicles used for business but also driven home. Since then, Inland Revenue has advised that they have been working to refine the proposals, seeking a balance between administrative simplicity and policy integrity. In my view, the proposed tweaks, if adopted in legislation, should work well to address the issues, bring the FBT rules up to date with how businesses own and run vehicles today, and compensate for the loss of the work-related vehicle exemption.
What’s Changing?
The current FBT regime is widely regarded as outdated, overly complex, and out of step with how modern businesses operate. The key focus of reform is motor vehicle benefits, where the treatment of “availability for private use” rather than actual use has led to disputes, confusion, and avoidance opportunities.
The proposals included:
- The work-related vehicle exemption will be repealed, ending a long-standing concession that allowed certain business vehicles, most notably double cab utes, to be largely excluded from FBT.
- FBT will shift to a usage-based framework, categorising vehicles into four tiers based on their level of private use, with set FBT rates for each.
- The PERC threshold (Private Employee-Related Car rule) is being discussed, providing clarity for major shareholder-employees who use high-value utes for legitimate business needs (e.g. towing equipment).
- The introduction of the incidental travel rule.
Valuation and Reporting Changes
Other important shifts include:
- Logbooks are out. Instead of maintaining day-to-day records, vehicle use will be reassessed every four years using market valuation data (e.g. AA reports).
- Tax book value methods will be scrapped, with external valuations now forming the basis of FBT.
- Fuel-type differentials will apply — EVs and hybrids may attract reduced FBT rates due to their lower running costs.
- A new weight threshold of 4,500 kg (up from 3,500 kg) will better reflect modern ute and SUV sizes.
Refined Category Structure
One of the biggest issues was with the proposed Category Structures. The proposals categorised vehicle use into three groups, but there were two key issues with these categories:
- A vehicle driven by a shareholder-employee, with a cost of $80K or more (a PERK vehicle), could only be a category 1 vehicle, meaning it would be subject to FBT 100% of the time.
- As soon as a vehicle is available for use in the weekend, it would be a category 1 vehicle, meaning it would be subject to FBT 100% of the time.
Although not publicly available, I believe the Inland Revenue has made progress on these issues and I’m confident they will be resolved, provided the Revenue’s current recommendations are adopted in legislation.
Political Uncertainty
While the proposals have been well-signalled, there is still no clear implementation date. Following a media storm, the Government has commented that the reforms are still under ministerial consideration. We understand that legislation is being drafted, but ministers are reviewing whether and when to proceed.
Final Thoughts
The removal of the work-related vehicle exemption will fundamentally change how many businesses approach vehicle use, procurement, and remuneration. While the aim is simplification, there is potential for confusion as businesses adjust to the new rules — particularly around what constitutes Category 2 vs. Category 3 use, and whether vehicles require signwriting.
Employers should start preparing now by reviewing their vehicle fleets, identifying potential exposure, and considering whether adjustments (e.g. branding, usage policies, or vehicle pooling) might be required to maintain compliance or reduce FBT costs.
