While certainly not a joy ride, the progression of the proposed Division 296 tax on superannuation balances above $3 million has taken a few sharp turns – now featuring a re-engineered structure, new thresholds and a delayed start.
What’s changed
Following industry feedback, the federal Treasurer has responded with several key changes:
- A two-tier threshold approach;
- Indexation of the thresholds;
- Earnings to be calculated on a realised basis (not unrealised); and
- Delayed commencement of the provisions for 12 months to 1 July 2026.
There will be a consultation period which will invite stakeholders to weigh in on:
- The calculation of realised earnings;
- The extension of exemptions for some judges – to improve consistency across jurisdictions; and
- Any additional changes to ensure that treatment is fair and equitable for defined benefit members.
What’s not changed
Despite the above announcement, there are elements of the provisions that have not changed:
- The ultimate objective of the Division 296 proposal remains the same – “maintain the concessional tax treatment of superannuation for all members but make these concessions more sustainable”;
- The tax will still be levied on the individual, who can choose to pay the tax from their superannuation or personal sources;
- The member’s Total Superannuation Balance (TSB) remains the measure for determining the additional tax liability; and
- The ability to carry forward any losses and offset against future year’s earnings to reduce the tax.
Changes in detail
Two-tier threshold
Where previously the proposal was focussed on individuals with a TSB of more than $3 million, the adjustments now alter this focus to two tiers. The provisions will now include:
Noting that the above 15% and 25% are in addition to the 15% income tax that superannuation funds already pay on taxable income (although this may be reduced by long-term capital gains discounts or as low as nil where the Fund is wholly in pension phase).
Indexation of thresholds
The previously proposed legislation recorded a fixed $3 million threshold, with no option for indexation. Refreshingly, thresholds will now be indexed using the Consumer Price Index (CPI). These changes will align the indexation approach with other measures such as the indexation of the Transfer Balance Cap (TBC).
However, similar to the indexation of TBC, the indexation to the thresholds will only occur where the CPI increases by a certain amount, and the application of that amount results in the increase of the threshold reaching the stated increment. The indexation rules for the thresholds will be:
Importantly, this indexation ensures that the number of individuals captured by the new tax remains consistent with the original policy intent, rather than growing disproportionately over time.
Calculation of earnings
Due to the inclusion of unrealised capital gains, the previous calculation of earnings was the most contentious part of the original proposed legislation. The most significant feedback with regards to this was that the taxing of unrealised capital gains was unconstitutional, and that any passing of the law would lead to a constitutional challenge.
The original proposal suggested that the Earnings would be calculated as:
The adjustments indicate that while a member’s Total Superannuation Balance (TSB) will remain the key reporting measure, the ATO will obtain realised earnings information directly from the member’s superannuation fund where the TSB exceeds the relevant thresholds.
According to Treasury, these realised earnings will generally reflect the fund’s taxable income, adjusted for member contributions and exempt current pension income (with detailed rules still to be confirmed).
For SMSFs, this information is expected to be reported through the SMSF Annual Return, with each member attributed a fair and reasonable proportion of the fund’s realised earnings.
While this is a positive outcome where only realised income and gains are taxed, it may create practical challenges for large APRA-regulated funds, which will need systems capable of attributing realised gains, losses, and income to individual members. The intention, however, is for the calculation to align with existing tax concepts and use current reporting mechanisms wherever possible to minimise additional compliance burdens.
Practical application
The methodology for calculating an individual’s liability has not been finalised or confirmed. However, Treasury have provided five broad steps detailing how to arrive at the liability.
- The ATO will determine whether an individual is “in scope” (has a TSB of $3 million or more) and will notify the applicable superannuation funds;
- The applicable funds will calculate the realised earnings attributable to the individual and report the amount back to the ATO (as above, this is expected to be reported on the SMSF annual return, so this step would occur in conjunction with step 1, once the Fund’s relevant return has been lodged);
- The ATO will calculate the proportion of TSB above the $3 million threshold, utilising the original proportion calculations:
4. ATO will calculate the proportion of the TSB exceeding the $10 million threshold
5. ATO will calculate the tax liability for the individual’s TSB interests:
Examples
The below examples are based on a SMSF having total earnings of 10% (including unrealised capital gains), on their TSB at 30 June 2026 (which are $8 million and $15 million respectively), where the realised earnings is 10% of the total earnings. There are two examples – one within the upper threshold, and one above the upper threshold.
Note, we have not considered contributions in the realised earnings figure, as there is currently no drafted formula for this figure. We note that taxable income of a Fund would include assessable contributions, so the below examples assume no such contributions for any adjustment required to be made.
$8 million TSB at 30 June 2026
$15 million TSB at 30 June 2026
Challenges
While the latest changes are broadly welcomed (short of the tax being abolished altogether), several practical and policy issues remain to be resolved through consultation and the legislative process:
- Reporting complexity
SMSFs will be able to calculate and report realised earnings through their annual return with relatively minor adjustments, even though member level reporting isn’t currently required. However, large industry and retail (APRA-regulated) funds may face significant challenges in adapting systems to attribute realised gains, losses and income to individual members. - Higher-tier tax impact
The introduction of the additional 10% tax for balances above $10 million is unlikely to be well received by those with substantial superannuation holdings. - Legislative consultation required
These updates represent a major redesign of the original Division 296 proposal. As the changes were announced without prior stakeholder consultation, the next phase will involve detailed consultation and Parliamentary debate before any legislation is finalised.
Key takeaways
- Commencement has been delayed until 1 July 2026. This means the first assessments for the 2026/2027 year will be issued in the 2027/2028 financial year, so effectively two years from now.
- Changes have made the earnings calculation fairer, by ensuring only realised earnings will be taxed (not unrealised capital gains).
- There will be a two-tiered threshold system, being:
- $3 million – where up to an additional 15% tax will be payable on earnings
- $10 million – where up to an additional 10% tax will be payable on earnings (in addition to the amount payable as a result of the $3 million threshold)
- The two thresholds will be indexed by CPI in different increments:
- $3 million threshold – at $150,000 increments
- $10 million threshold – at $500,000 increments
- Superannuation will remain a tax efficient structure for the accumulation of wealth for retirement and over the longer term, despite these changes. It will be important to seek specialist advice prior to making any investment or withdrawal decisions to ensure that all qualitative and quantitative elements are considered.
Next Steps
For now, keep your hands inside the ride and hold on tight. We suggest not taking any impulsive actions and to wait for the new legislation to be put forward. We will keep you abreast of when the updated draft legislation is released, at which point it may be appropriate to review your own situation to understand how this will affect you.
