Proposed FBT changes on motor Vehicles
If you’ve ever dealt with Fringe Benefit Tax (FBT), you’ll know it can be one of the more frustrating parts of running a business. Between tracking vehicle use and keeping logbooks, it’s not exactly straightforward.
The Government is looking to change that, with proposed changes expected to apply from 1 April 2027. At this stage though, it’s important to stress that these are still proposals only. The legislation hasn’t been finalised, and the details could change before anything becomes law. So for now, there’s nothing you need to do differently — but it’s worth understanding what’s being considered.
The main focus of the proposed changes is how FBT applies to company vehicles. Under the current rules, you need to determine whether a vehicle is available for private use, which often means keeping detailed records, tracking days, and in many cases maintaining logbooks. It can be time-consuming and tedious.
The proposal is to introduce a simpler, category-based system. Rather than tracking actual usage, vehicles would be grouped based on how they are generally used, and a set percentage would be applied.
The proposals are:
Category Type of Use Indicative FBT Treatment
Full private use Vehicle is essentially provided as a perk 100% taxable
Partial private use Mainly business use, but some personal use allowed ~35% taxable
Minor private use Limited to commuting or very minor personal use Reduced rate (around 20%)
No private use Pool vehicles or strictly business use only 0% taxable
The idea is that instead of tracking usage throughout the year, you would assign a category when the vehicle is provided and only revisit it if the use changes. From a compliance point of view, this would remove the need for logbooks and day-by-day tracking, which will be appealing for many businesses.
That said, while the rules may become simpler, they won’t necessarily produce a better tax outcome for everyone. Standardised percentages mean some businesses could end up paying more FBT than they do under the current approach, particularly where private use is low and well documented. There’s also a bit more judgement involved upfront in deciding which category a vehicle falls into.
It’s also worth highlighting these proposed changes don’t affect all businesses in the same way. For close companies with shareholder-employees, the existing option of using a logbook and apportioning vehicle costs between business and private use is still available. This approach can allow you to avoid FBT entirely and instead claim deductions based on actual usage, which for some remains a more practical and tax-efficient method where private use is minimal.
You might find it useful to start thinking about how your vehicles are currently used and where they might sit under the new categories, but there’s no need to make any changes until the rules are finalised.
Overall, these proposals are part of a broader push to simplify FBT, which is something most businesses will welcome. Whether it results in a better outcome will depend on your specific situation, so it will be worth reviewing things carefully once we have confirmed legislation.
