Most family business owners have a complicated relationship with FBT — Fringe Benefits Tax.
Some have never thought about it. Others have been told by their accountant "it doesn't apply to you" without fully understanding why. And a few are running vehicles, paying for phones, and covering school fees through the business in ways that almost certainly do create an FBT liability — they've just never had to answer for it.
When you're running the business, this ambiguity tends to be manageable. You've been doing it for years. The ATO hasn't come knocking. You move on.
When you're selling the business, it becomes a problem.
Due diligence will surface your FBT position. Buyers' accountants know where to look. And an unexpected FBT liability — or worse, an unclear one — gives buyers exactly what they don't want: uncertainty they can't price.
A Full Federal Court ruling from April 2026 has clarified one of the murkiest parts of FBT law for family business owners: when does working in your own business actually make you an "employee" for FBT purposes? The answer matters more than most owners realise.
What FBT is — quickly
Fringe Benefits Tax is a tax paid by employers on certain non-cash benefits provided to employees (or their associates) in connection with employment. The most common examples in small and family businesses are:
- A company car (or any vehicle) available for private use
- Low-interest or interest-free loans from the business
- Entertainment expenses (meals, events, memberships) that benefit employees personally
- Payment of private expenses by the business (private school fees, personal insurance, rent)
- Provision of equipment or property for personal use
The critical word in all of this is employees. FBT only applies to benefits provided to employees — not to business owners as owners.
Which is where family businesses get complicated.
The owner/employee question
In most family businesses, the owner is also the person doing the work. They might also be the director, the trustee, the sole shareholder, and the person who opens the shop every morning.
For FBT purposes, none of that automatically makes them an employee.
In April 2026, the Full Federal Court confirmed this in a case involving a family business where the owner worked full-time in the operation. The Court found that working full-time in your own business does not, by itself, create an employment relationship for FBT purposes. The nature of the relationship — control, direction, the existence of an employment contract, how remuneration is structured — determines whether someone is an employee, not just the fact that they show up and do the work.
This matters for sellers because it cuts both ways.
On one hand: if you have genuinely been operating as an owner rather than an employee, you may not have an FBT liability for benefits you received. The car you've been driving for private purposes, the phone the business paid for — if you were never actually an employee, FBT may not have applied.
On the other hand: if you or a family member have been receiving benefits from the business as employees — with employment contracts, PAYG withholding, superannuation — then FBT does apply, and the business needs to have been lodging FBT returns and paying the tax accordingly.
The problem emerges when the structure has been informal. Many family business owners have blurred these lines for years — not out of dishonesty, just because the distinction never mattered until now.
Why buyers care
Buyers care about FBT for two reasons.
First, unpaid FBT liability can transfer. If the business has employees who received fringe benefits and the business never lodged FBT returns or paid the tax, that liability exists whether or not the business was sold. In an asset sale, the buyer generally doesn't inherit the liability directly — but they will want it resolved before settlement, and they'll want price certainty around it. In a share sale, the FBT history follows the company and the buyer inherits it outright.
Second, FBT compliance tells a story about how the business was run. A business with clean FBT records — returns lodged, tax paid, vehicle logs maintained — signals professional management. A business where "we never really thought about FBT" signals something else: that financial compliance may have been treated casually in other areas too.
Due diligence is as much about pattern recognition as it is about specific numbers. FBT is one of the clearest places where a buyer gets a signal about how rigorous the financial management has been.
The vehicles issue specifically
Vehicle use is the most common FBT question in family business due diligence, and it deserves specific attention.
If the business owns a vehicle — a ute, a car, a company van — and that vehicle is available for the private use of an employee (or an associate of an employee), a car fringe benefit arises. The taxable value of that fringe benefit is calculated either under the statutory formula method (based on the car's value and availability) or the operating cost method (based on actual costs, with private use logged).
The April 2026 Full Federal Court decision is relevant here: the question of whether the person using the vehicle is an "employee" is not always obvious in a family business context. If the owner is not classified as an employee, FBT on the vehicle used for their private trips may not apply. If a spouse or adult child who works in the business is an employee, FBT on their vehicle access probably does apply.
The difficulty is that many family businesses have never done the analysis. The accountant has been focusing on income tax and GST. The FBT position has been treated as "handled" without anyone actually confirming how.
Before a sale, get your accountant to walk through every vehicle the business owns or leases, who uses it, whether those people are employees, and what the FBT position actually is. This takes a few hours. It's worth it.

When buyers' accountants review the financial records of a family business, they're specifically looking for:
- FBT returns: Have they been lodged? For every year where there were employees? Are they consistent with the employee list and the benefits provided?
- Vehicle log books: If the operating cost method was used, is there a compliant log book? Log books need to cover a minimum 12-week period and be renewed at least every five years (or when a new vehicle is acquired).
- Salary packaging arrangements: If employees have been packaging benefits as part of their remuneration, is it documented? Has it been reflected correctly in the FBT return?
- Employer-paid expenses: Are there items in the accounts (phone bills, memberships, entertainment, private schooling) that look like they might be fringe benefits? If so, has FBT been considered?
The standard for "clean" is not perfection — it's completeness. A business that has lodged FBT returns showing a liability, paid the tax, and can explain its methodology will fare far better in due diligence than one that has no FBT records at all and no clear answer to why not.
What to clean up before you go to market
If you're preparing for a sale in the next one to three years, here's what's worth addressing now:
1. Clarify the employee question
Sit down with your accountant and ask: for each person in the business (including you, your spouse, adult children, and any family members who receive benefits), is this person an employee for FBT purposes? Make sure the answer is documented. The April 2026 Full Federal Court ruling means this question has a clearer framework — use it.
2. Audit the benefits actually provided
Go through the last three years of expenses and identify anything that could be classified as a fringe benefit. Vehicles, phones, laptops, entertainment, travel. For each item: was it used for business or private purposes? If the person receiving it is an employee, has FBT been considered?
3. Check your FBT return history
If your business has (or has had) employees, you should have FBT returns lodged for years where fringe benefits were provided. If there are gaps, talk to your accountant about whether a voluntary disclosure to the ATO makes sense. Voluntary disclosure before an audit is treated far more favourably than a liability discovered during one.
4. Start a log book if you don't have one
If a vehicle is owned by the business and used at all for private purposes by an employee, start a log book now. A current, compliant log book is one of the simplest things you can do to bring certainty to the vehicle question. Without one, the statutory formula method applies by default — and depending on the value and usage of the vehicle, this can produce a higher taxable value than the operating cost method.
5. Disclose proactively if there's uncertainty
If, after going through the above, you find that FBT should have been applied in years past and wasn't — don't hide it. Quantify it as best you can, get your accountant's assessment of the total exposure, and disclose it as part of your pre-sale preparation. A known, quantified issue is manageable. An unknown one, surfaced mid-due-diligence, is a deal negotiation at the worst possible time.
The broader point: clean businesses sell better
FBT is one piece of a larger picture. Buyers — particularly buyers of businesses above $500,000 in value — are doing a systematic review of tax compliance, not just a snapshot. They're looking at income tax, GST, FBT, payroll tax, and superannuation. They're checking whether each area has been managed properly.
Most family business owners will find, when they actually go through this exercise, that their position is either genuinely clean (many are) or has specific gaps that can be resolved before going to market.
The owners who sail through due diligence with minimal price adjustment are the ones who treated compliance as an ongoing discipline, not a once-a-year obligation. Their records are in order. Their positions are documented. They have answers ready.
The ones who lose the most ground in due diligence are the ones who encounter these questions for the first time when a buyer's accountant is asking them — under time pressure, in a context where uncertainty costs money.
The gap between those two outcomes is rarely about the actual compliance position. It's about preparation.
Note: The Full Federal Court decision referenced in this article clarified the owner/employee distinction for FBT purposes in the context of family businesses. It does not override the need for specific advice about your structure. FBT rules are applied based on the facts of each situation — talk to your accountant about how the ruling applies to you.
