Highlights

  • Division 296 would apply the same additional 15% tax framework to SMSF and managed fund members whose total superannuation balances exceed AUD 3 million.
  • While the tax rules are fund-type neutral, SMSF trustees have greater responsibility for valuations, record-keeping, and liquidity management.
  • Managed fund members benefit from fund-level reporting and administration but still need to understand their aggregated superannuation position across all accounts.
  • The proposed treatment of unrealised gains, valuation requirements, and threshold indexation remain important areas to monitor before implementation.

Most discussion of the proposed Division 296 measure focuses on the headline figure: an extra tax on superannuation balances above $3 million. Less attention is paid to a practical question that matters enormously to members, namely how the measure plays out depending on the kind of fund you are in. The experience of a self-managed superannuation fund (SMSF) trustee can differ markedly from that of a member of a large, professionally managed fund, even though both face the same underlying rules.

This article compares the two. It explains how reporting, valuation and the practical mechanics differ between SMSFs and APRA-regulated managed funds, and why the proposal may serve as a useful prompt for trustees and members alike to review how their fund operates. It is general information, written calmly, and is not advice.

Direct answer: a quick summary

Division 296 is a proposed Australian measure adding 15 per cent tax on 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 rules are the same regardless of fund type, but the practical handling differs: SMSF trustees are responsible for valuations and records, while managed funds prepare and report figures for their members. The original design's earnings methodology and un-indexed threshold remain debated and subject to final legislation.

Why this matters now

The proposal lands at a time when many members give little thought to how their fund actually reports and values assets. For SMSF trustees in particular, the measure highlights responsibilities that have always existed but may not always have been front of mind. For managed fund members, it underlines a reliance on the fund's processes that is usually invisible.

Timing matters because the design and start date are still being settled. That gives both groups a window to understand how their fund will handle the calculation before it applies, rather than discovering the practical implications after the fact.

There is also a fairness-of-experience angle. Because the measure relies on accurate, timely balances and valuations, the quality of a fund's processes affects how smoothly any liability is calculated and met. The proposal is, in this sense, a prompt to check that those processes are robust.

Who may be affected

The measure applies to individuals with a total superannuation balance above $3 million, tested across all funds at year-end. The test is individual, combining balances across every fund a person holds, whether SMSF or managed.

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

Crucially, a member may hold both an SMSF and one or more managed funds. Because balances aggregate at the individual level, such a member experiences both worlds of reporting at once, which makes understanding the differences especially relevant.

What investors should understand

The extra tax is proportional, applying only to earnings attributable to the part of a balance above $3 million, calculated as the amount above the threshold divided by the total balance. This calculation is the same whatever fund holds the assets.

The most debated feature of the original proposal is the earnings methodology. By measuring the year-on-year change in balance, adjusted for contributions and withdrawals, the original design could include unrealised gains. This places weight on how assets are valued at year-end, which is precisely where SMSFs and managed funds can differ in practice. The methodology should be treated as an original-proposal feature subject to final legislation.

The individual is liable and can generally elect to pay personally or from super. How easily that liability can be funded depends partly on the liquidity of the underlying assets, which again varies by fund type.

SMSF and managed super fund considerations

This is the heart of the comparison. The two fund types share the same rules but diverge in how the rules are administered and experienced.

How SMSFs handle it

SMSF trustees are directly responsible for the fund's records, asset valuations and compliance. Many SMSFs hold illiquid or hard-to-value assets, such as direct property, unlisted investments or concentrated parcels of shares. Valuing these accurately at year-end is the trustee's job, and the quality of that valuation feeds directly into any earnings figure.

Liquidity is the other distinctive feature. Where an SMSF holds a large, indivisible asset, an earnings figure that includes unrealised gains could in principle create a liability without a corresponding cash inflow. Trustees therefore need to think ahead about how any liability would be funded, whether from within the fund or personally. The measure rewards disciplined administration: timely valuations, clear records and a realistic view of liquidity.

How managed funds handle it

Members of large APRA-regulated funds rely on the fund's systems. The fund values assets, maintains records and reports the relevant figures, which are then aggregated by the regulator and the tax office to determine an individual's position across all funds. Most assets in these funds are liquid and regularly priced, so valuation is generally more straightforward and less contentious.

The member's experience is correspondingly more hands-off. The practical focus shifts from preparing figures to understanding them, checking that aggregated balances look right, and deciding how to fund any liability. The trade-off is less control but also less administrative burden.

It is worth noting that this convenience comes with a quieter responsibility. Because figures arrive prepared, members can be tempted to accept them without scrutiny. A sensible habit is to check that statements reconcile, that all accounts are captured, and that the aggregated total reflects every fund held. The measure makes this routine diligence more valuable, since the year-end figure now carries direct tax consequences for those above the threshold.

Bringing the two together

For members who hold both, the key is that balances combine at the individual level. A complete picture requires gathering figures from each fund, reconciling them, and understanding that the SMSF portion will demand more personal attention than the managed portion. The measure is a reminder to view all funds as a single, aggregated whole.

In practice, this combined view is where many high-balance Australians will find the proposal most relevant. An SMSF balance and a managed fund balance that each sit comfortably below $3 million can together exceed it. Without a consolidated picture, a member could underestimate their position entirely. Bringing the figures together, ideally with professional help, is the single most important administrative step the measure encourages.

Possible planning options to discuss with an adviser

These are areas commentators discuss generally. They are not recommendations and depend on individual circumstances. Explore them with a licensed adviser and tax specialist.

  • Reviewing SMSF valuation processes and the timing of year-end valuations.
  • Assessing fund liquidity so any liability can be met without forced asset sales.
  • Reviewing voluntary contribution plans across all funds in light of the threshold.
  • Considering partial withdrawal and recontribution strategies where eligible.
  • Considering whether some assets sit better outside super, such as in trusts or investment bonds.

Risks and uncertainties

The central uncertainty is that the proposal is not final. Both design and start timing have shifted during debate, and the unrealised-gains methodology and the absence of indexation remain contested. Trustees and members should prepare their processes without over-committing to a design that may change.

For SMSFs specifically, there is execution risk in restructuring illiquid holdings, which can crystallise capital gains tax, duties and compliance costs and may not be easily reversed. For managed fund members, the main risk is passivity: relying entirely on the fund without understanding the aggregated position across all of their super.

As always, super remains concessionally taxed under the proposal. The measure is a prompt to check processes, not a reason to abandon a structure that may continue to serve well.

What to watch before 1 July 2026

The source frames a potential start around 1 July 2026, treated here as indicative and subject to final legislation. Signposts include:

  • Whether the final earnings methodology retains any treatment of unrealised gains.
  • Whether the $3 million threshold is indexed in any final form.
  • The confirmed start date and any transitional arrangements.
  • Guidance on valuation standards, especially for illiquid SMSF assets.
  • How balances across SMSFs and managed funds will be aggregated and reported.

Key takeaways

  • Division 296 applies the same rules to SMSFs and managed funds, but the practical handling differs.
  • SMSF trustees are responsible for valuations, records and liquidity; managed funds report figures for members.
  • Illiquid SMSF assets make valuation and liquidity planning especially important.
  • Managed fund members should still understand their aggregated position across all funds.
  • The unrealised-gains methodology and un-indexed threshold remain debated, original-proposal features.
  • Use the proposal as a prompt to check fund processes; confirm final detail against legislation.

Definitions

Division 296

A proposed Australian measure applying an additional 15 per cent tax on earnings attributable to the part of an individual's total superannuation balance above $3 million.

SMSF

A self-managed superannuation fund, run by its members as trustees who are directly responsible for investment, valuation, record-keeping and compliance.

Superannuation balance and TSB

Total superannuation balance is the combined value of an individual's super across all funds, SMSF and managed, used to test the $3 million threshold.

Tax-effective strategy

A lawful way of arranging investments and structures to manage tax, suitable only where it fits an individual's circumstances and advice.

Trusts

Legal arrangements in which a trustee holds assets for beneficiaries, including family and discretionary trusts sometimes used outside super.

Bonds

Investment or insurance bonds: tax-paid investment products where earnings are taxed within the bond rather than in the investor's hands.

Retirement planning

Organising savings, investments and structures to fund retirement while balancing tax, liquidity and risk.

Conclusion

Division 296 may prove most valuable not as a tax to be feared but as a prompt to look closely at how a fund actually works. SMSFs and managed funds face the same rules, yet the lived experience of valuation, reporting and liquidity can differ sharply between them. Understanding that difference is the practical heart of preparing for the measure.

With the design and timing still to be confirmed, both trustees and members are best served by tightening their processes now: accurate valuations and records for SMSFs, a clear understanding of aggregated figures for managed fund members, and a realistic view of liquidity for everyone near the threshold. Treated as a wake-up call rather than an alarm, the proposal can leave both kinds of fund better run regardless of where the legislation lands.
