Earlier this week, The Australian Financial Review noted that WiseTech director Charles Gibbon’s December 2024 sale of 1.53 million shares in the $33 billion software firm was actually executed through the trustee for his self-managed super fund.
Fabemu No. 2 Pty Ltd acts as the trustee for the Gibbon Superannuation Fund, which based on its remaining holding of WiseTech shares, could be the largest SMSF in the country.
When Fabemu No. 2 sold the shares on 5 December, it was to the tune of around $200 million. As the assets were held within super, the capital gains on the sale were likely 10 per cent, which is considerably lower than the bill would have been had Gibbon held the shares outside of super.
But it’s the volume of shares still held in the SMSF that is most notable, with a change of director’s interest notice following the sale disclosing that Fabemu No. 2 owns 15,594,630 more shares.
As at close of trading on Thursday afternoon, with the stock sitting at $108.77, this is valued at around $1.69 billion.
While the ATO hasn’t disclosed exact values for the largest SMSFs, it has previously detailed that the average for the top 10 was $423 million.
Even among the extreme end of the spectrum, Gibbon is an outlier. And that’s before taking any non-WiseTech holdings into account.
So, would he be on the hook for if the Division 296 tax were already in place and applied to just the value of Gibbon’s WiseTech SMSF holding?
Using the SMSF Alliance calculator for the tax as it is currently proposed, if the share price ended in the same spot at close on 30 June, the Division 296 bill would be a little over $31 million.
Ouch.
This is based on no contributions or withdrawals being made and a starting balance of $1.48 billion – which is the value of the same amount of WiseTech shares at 1 July 2024.
Now, is this definitively what the tax hit would be? Absolutely not. It’s just a range based on publicly available information that takes no other circumstances into account.
But it is an example of the kind of superannuation holdings that the government has made abundantly clear it doesn’t support.
There’s no credible case that anyone with more than a billion dollars in their super should have access to the same level of tax concessions as someone with even an above average balance. At that point, it quite clearly has nothing to do with saving for retirement.
Whether it leads to Gibbon ever paying the tax or it simply prompts him to move it into a different structure, this is the kind of wealth hoarding within super the Treasurer is aiming to curb.
What impact does the tax actually have on other large balances?
One of the major misconceptions around the proposed $3 million super tax is what portion of the balance above the threshold is impacted.
It isn’t the entire increase in total super balance (TSB) that is taxed at the additional 15 per cent rate, only the earnings – yes, including unrealised gains – that are attributable to the balance above $3 million.
Before the tax is calculated, the percentage of growth that is taxable needs to be determined, which at a high level is a fairly simple formula: (TSB at end of FY) – $3 million (large balance threshold) ÷ (TSB at end of FY).
Earnings for Division 296 purposes is calculated as TSB at end of the financial year minus the greater of TSB at start of the financial year or $3 million.
This also needs to be adjusted by removing after tax contributions and adding back withdrawals, including pension payments.
Then, the actual tax is 15 per cent of earnings x taxable portion.
Assuming no after-tax contributions or withdrawals for the sake of simplicity in this example, a super balance that moved from $3 million (or indeed any amount below $3 million) up to $3,250,000, only 7.69 per cent of the growth is actually taxable.
That equates to earnings of $19,225 actually subject to the 15 per cent tax, ultimately putting the bill at just $2,883.75.
The taxation of unrealised gains is fundamentally bad policy, but the arguments against it should avoid overstating the actual impact on the vast majority of funds that are going to be hit with a bill.




I’m a liberal voter and even i agree if you have 10 million or more you should be paying 30% tax. It annoys me how it excludes judges (their staff), former premiers, Prime ministers, etc etc.. Why the ruling elites get to buck the system. Libs are wasting their time fighting this one.
Be warned that the The STANDARD YOU WALK PASSED IS THE STANDARD YOU ACCEPT. If you accept that taxing unrealised gains is good for the $3m+ balances holders, then your argument later if applied to all balances or non-sup assets will be weakened.
Very few people have a problem with the intention of Div 296. But a lot of people have concerns about its clunky design. There is a far simpler, more equitable way to do it. Just move all accumulation fund balances for people aged over 65 into a separate account type, taxed at 30% in the normal super fund way without unrealised capital gains.
Everyone would still have the option to transfer up to $2M to an ABP for completely tax free super, and this $2M threshold (Transfer balance Cap) is already indexed.
This would also provide greater incentive to utilise ABPs in retirement rather than retaining in accumulation.
Sensible
Because you arent lookiing at their long game.
Do you really think that once the concept of taxing unrealised capital gains in super is cemented within the tax system, they won’t then move on private assets ????
Wake up people.
Yes the overwhelming industry consensus isn’t opposed to reducing concessions where appropriate. The form chosen by the government leaves a huge amount of grey area, especially around valuations.
It would be amazing if Labour was just transparent about what consultations they have actually undertaken in this space as I haven’t seen any support whatsoever for the measure as it stands. Why should we trust their motives if they can’t even give us a transparent view of what steps were taken to formulate this idea.
Sounds like you are a treasurer in waiting…
The current clown Chalmers needs to go as he and his mates have no idea about basic economics!
Why can’t government push that $3mil to $30 mil which will actually target the ones that government is really targeting instead of hard working middle class Australians
Hey! I’m a hard working middle class Australian with a super balance of $31M. The threshold should obviously be $32M to catch rich people! Not battlers like me!
That’s funny.
Good.
So, what are your thoughts on Ablo’s Pension?
That is hardly the point.
If you think the taxation of unrealised capital gains is good policy then maybe you need to think again.
Neither is Green…
