Highlights

  • Division 296 would introduce an additional 15% tax on earnings attributable to the portion of an individual's total superannuation balance above AUD 3 million.
  • Early planning focuses on understanding total super balances, liquidity needs, valuations, and potential exposure before any rules take effect.
  • The original proposal's treatment of unrealised gains and the absence of threshold indexation remain key areas of uncertainty.
  • Preparing options rather than making irreversible changes may help investors adapt as the final legislative details emerge.

Good tax planning is rarely about dramatic moves. More often it is about reviewing assumptions early, keeping records in order and understanding how a proposed change might interact with an existing strategy. The Division 296 measure, which targets superannuation balances above $3 million, is a clear case in point. The most useful response is not a scramble to restructure, but a structured review undertaken before any rules take effect.

This article offers a pre-emptive, general planning framing. It walks through what the proposal does, why a review is worthwhile now, and the kinds of questions worth working through with a licensed adviser. It is a checklist of considerations, not a set of recommendations, and it deliberately avoids fear-based framing.

Direct answer: a quick summary

Division 296 is a proposed Australian measure adding 15 per cent tax to the earnings attributable to the portion of an individual's total superannuation balance above $3 million, assessed per person across all funds at year-end. The original design measured earnings via the change in balance, potentially including unrealised gains, and did not index the threshold. Because timing and design have shifted in debate, sensible planning prepares for the proposal while confirming final detail against the legislation.

Why this matters now

Planning ahead of a change is almost always easier than reacting to one. While the proposal is still being finalised, individuals can gather information, model scenarios and align their affairs without time pressure. Once rules commence, options can narrow and decisions may need to be made under tighter constraints.

There is also a record-keeping dimension. The original earnings methodology relies on accurate balances and valuations, especially for less liquid assets. Getting records and valuations in order now is valuable regardless of how the final design lands, and it is far simpler than scrambling later.

Finally, planning early helps separate signal from noise. The proposal has attracted strong commentary, some of it speculative. A calm, structured review focuses attention on what is actually proposed and what it means for a specific situation, rather than on headlines.

It is worth adding that planning is a process, not a single event. A review undertaken now can be revisited as the legislation firms up, with each pass refining the picture. Treating the proposal as a prompt to build a durable habit of annual review, rather than a one-off task, tends to produce steadier outcomes and fewer surprises when rules eventually take effect.

Who may be affected

The measure applies to individuals whose total superannuation balance exceeds $3 million, tested across all funds at year-end. Because the test is individual, it is assessed person by person rather than per household.

Affected individuals commonly include long-term savers, business owners who made large contributions, and members whose assets have appreciated. Initially this is a small share of all account holders, in the tens of thousands, though the un-indexed threshold in the original design means the group could broaden over time.

From a planning standpoint, it is worth knowing not only whether you are over the threshold today, but whether you are likely to approach it within your planning horizon. Those near the line have the most to gain from an early, considered review.

What investors should understand

The extra tax is proportional, applying only to earnings attributable to the part of a balance above $3 million. The proportion is the amount above the threshold divided by the total balance, so exposure scales with how far a balance sits above the line.

The most debated planning factor is the original earnings methodology. By measuring the year-on-year change in balance, adjusted for contributions and withdrawals, the original design could include unrealised gains, meaning tax might apply to paper gains not yet realised through a sale. This matters for cash flow and liquidity planning and should be treated as an original-proposal feature subject to final legislation.

The individual is liable and can generally elect to pay from super or personally. That election is itself a planning decision, with implications for liquidity and the amount of capital left compounding inside super.

A further point worth grasping is the year-end nature of the test. Because the threshold is assessed on the balance at the end of the relevant period, the timing of contributions, withdrawals and even market movements around that date can influence the outcome. This is not an invitation to engineer a balance, but it does mean that understanding how and when figures are struck is part of informed planning, and a reason to keep clear records throughout the year rather than only at reporting time.

SMSF and managed super fund considerations

Planning differs in practice between self-managed superannuation funds (SMSFs) and large APRA-regulated funds. SMSF trustees are responsible for valuations, records and meeting any liability, and often hold illiquid assets such as property or unlisted investments. For these members, liquidity planning and disciplined valuations are central, because an earnings figure that includes unrealised gains could create a liability without a matching cash inflow.

Members of managed funds have much of the reporting and calculation handled for them, with figures aggregated by the relevant authorities. The planning emphasis shifts toward understanding the numbers provided and deciding how to fund any liability.

For anyone with balances in both types of fund, the individual-level aggregation is the key planning fact: balances combine across all funds to test the threshold, so a consolidated view is essential.

A practical implication for trustees is to begin engaging valuers and advisers earlier in the cycle than they might otherwise. Where assets are unique or thinly traded, obtaining a defensible valuation can take time, and leaving it to the last moment can compromise both accuracy and the ability to plan around the result. Building valuation discipline into the fund's ordinary administration is a low-cost step that pays off whatever the final rules.

A pre-emptive planning checklist

The following are general considerations to work through with a licensed adviser and tax specialist. They are not recommendations and suitability depends on individual circumstances.

  • Establish your current total super balance across every fund, not fund by fund.
  • Project whether you are at, above, or approaching the $3 million threshold within your horizon.
  • Review valuations and records, especially for illiquid SMSF assets.
  • Assess liquidity, so any future liability can be met without forced asset sales.
  • Reconsider the size and timing of voluntary contributions in light of the threshold.
  • Discuss whether partial withdrawal and recontribution strategies are available and appropriate.
  • Consider whether some assets sit better outside super, for example in trusts or investment bonds.
  • Decide, in principle, how any liability would be funded if the measure proceeds.

Possible planning options to discuss with an adviser

Commentators discuss several options in general terms. None is recommended here; each depends on circumstances and licensed advice.

  • Reviewing voluntary contribution strategies.
  • Partial withdrawals and recontribution where a member is eligible.
  • Holding selected assets through family or discretionary trusts.
  • Using investment (insurance) bonds as an alternative tax-paid structure.
  • Philanthropic structures for those with charitable goals.

Risks and uncertainties

The principal risk in any pre-emptive planning is acting on a proposal that is not final. Design and timing have shifted during debate, and the unrealised-gains methodology and lack of indexation have drawn particular scrutiny. Planning should therefore prepare options rather than commit irreversibly.

Restructuring carries its own costs. Moving assets or changing structures can crystallise capital gains tax, duties and compliance obligations, and may not be reversible cheaply if the final rules differ from the proposal.

It is also worth keeping perspective: super remains a concessionally taxed environment under the proposal. The goal of planning is to protect a coherent strategy, not to abandon a structure that may still serve well.

What to watch before 1 July 2026

The source frames a potential start around 1 July 2026, treated here as indicative. Key signposts include:

  • Whether the final earnings methodology retains any treatment of unrealised gains.
  • Whether the threshold is indexed in any final form.
  • The confirmed start date and any transitional arrangements.
  • Guidance on valuation and reporting for the calculation.
  • The process for electing how any liability is paid.
