Division 296: How the new super tax works (including calculator)

Important: Although this proposed measure is scheduled to begin from 1 July 2025, it is not yet law. The details below may change if legislation is amended or not passed.

If the Albanese Government has their way, a new tax will be charged on investment growth that occurs this financial year in super balances above $3 million (Division 296 tax).

If your balance is above $3 million on 30 June 2026, you will be among the first to receive an assessment.

The government recognises that the tax rates on super earnings of 15% in the accumulation phase and 0% in the retirement phase provide a significant concession for most taxpayers. Applying additional tax on the growth of larger balances is intended to better target that concession.

Let our explainer and calculator cut through the jargon.

Who does it apply to?

Division 296 tax applies to the taxable super earnings of individuals with total superannuation balances (TSBs) over $3 million at the end of a financial year. If your TSB is below $3 million on 30 June, the tax does not apply, even if you have made withdrawals to bring your balance below the threshold.

The $3 million threshold will not be indexed (at least initially), which means more people will be liable for Division 296 tax over time as super balances increase.

The threshold applies to individuals, so couples can still have up to $6 million in super and not be liable for additional tax. Individual application also means the total value of a self-managed super fund (SMSF) may be above $3 million but if no members have an individual TSB above the threshold then no Division 296 applies.

How is it calculated?

Division 296 tax at the rate of 15% applies to the earnings attributed to the portion of your balance that is above $3 million. This means if your balance is only a little over the threshold, a correspondingly small proportion of your earnings will attract extra tax.

Division 296 tax = 15% x taxable earnings x taxable proportion

To calculate the proportion, the below formula is used and rounded to two decimal places:

Taxable proportion

[(your TSB at the end of the year – $3 million)/ your TSB at the end of the year] x 100

The result is expressed as a percentage.

Example: Proportion

Runi has a total super balance of $4.5 million on 30 June 2026.

The proportion of her balance above $3 million is:

[($4.5 million – $3 million)/$4.5 million] x 100

=$1.5 million/$4.5 million x 100

= 33.33%

To calculate ‘earnings’ your 30 June Total Super Balance (TSB) from the prior year is subtracted from your most recent ‘adjusted’ 30 June TSB. Your adjusted TSB is your total balance with the year’s net contributions subracted and withdrawals added. Adjusting the figure this way ensures that only investment growth is captured, disregarding contributions and withdrawals.

However, as widely criticised, the calculation does capture the increase in value of assets that have not been sold (unrealised capital gains). Capital gains are not otherwise taxed in super or other contexts until the asset is sold and the gain is ‘realised’.

If your adjusted TSB or TSB from last 30 June is below $3 million, that figure is replaced with $3 million.

Example: Previous TSB above $3 million

James’ adjusted TSB on 30 June 2026 is $3.4 million. His TSB on 30 June 2025 was $3.1 million.

James’ taxable earnings for 2025-26 are $300,000 ($3.4 million – $3.1 million).

Example: Previous TSB below $3 million

Sunita’s adjusted TSB on 30 June 2026 is $3.1 million. Her TSB on 30 June 2025 was $2.8 million.

Sunita’s taxable earnings for 2025-26 are $100,000 ($3.1 million – $3 million).

Because her TSB on 30 June 2025 was below $3 million, the $3 million figure is subtracted in its place. This ensures she pays tax only on the portion of her earnings that brought her balance above the $3 million threshold.

    How will this change affect super funds that own property? Does this mean property will need to be valued each year rather than every 2-3 years at present?

      Hi Des, There is no change to valuation practices specifically required by the new tax.
      However, as many SMSFs value property every three years their trustees will need to consider if more frequent valuation would be desirable – perhaps to avoid lumpy tax liabilities. APRA regulated funds (non SMSFs) are required to comply with the Prudential Standard for Investment Governance under which APRA expects funds to revalue assets on at least a quarterly basis.

    For the moment, disregarding arguments about the fairness or otherwise of increasing the tax for those fortunate/diligent enough to have built a super balance of $5M+ or $3M+, the one thing that nobody seems to be commenting on is the actual mechanism for implementing this – which is not only unfair but, it seems to me, could have profound and unanticipated effects on ASX trading markets at EOFY.

    The government commentary presents this as simply increasing the tax rate from 15% to 30% for the proportion of your super balance over $3M BUT THIS IS NOT WHAT IS ACTUALLY PROPOSED.

    Within the super fund the 15% tax rate applies to the fund’s taxable income (assessable income less ECPI) now, if we took the government top level overview at face value, someone with a super balance of say $6M (ie 50% of their balance is above $3M) might expect 50% of their fund’s taxable income to be taxed at 15% and the other 50% to be taxed at 30%.

    HOWEVER the government, recognising that this would be a nightmare to actually administer if they required the actual Funds to apply this system, has left the actual super tax system unchanged and decided to levy this as an additional tax at the personal level. The real problem is that, to come up with a simple method of calculating the personal fund income to tax, they have decided to tax Fund EARNINGS – which they have defined as the increase in a person’s super BALANCE.

    Yes, this means that you will get taxed not only on capital gains on shares sold but also on UNREALISED capital gains. Given that the annual performance of the ASX can be much greater or less than the average return this will result in a very lumpy tax impost dependant on the 30 June closing prices at the beginning and end of the FY.

    Anyone who invests in shares with low liquidity with will be familiar with the fact that the closing price of these shares can be moved significantly by even small orders at the end of the day. As a long term investor in such a company you regard this as insignificant “noise” overlying the long term performance but, under this new scheme, a member whose fund has a significant holding in such an illiquid company could face a large variation in personal tax if someone buys/sells a quite small position at close of play on 30 June.

    Since often the reason for the low liquidity is retained ownership by the founders – they could have a real problem if their holdings are held in their super and the EOFY closing price changes significantly.

    I could go on and on about the unforseen problems I can see here – but I suspect it is worth an article of it’s own.
