Division 296 uses a member's total super balance to decide how much extra tax applies above $3 million, and that balance comes straight from a fund's financial statements. One accounting choice can move it: whether, and how, the fund recognises tax it may owe in future on gains it has not yet sold. This is the domain of tax-effect accounting, and while it sounds like a technicality for accountants, it can nudge a member's reported balance up or down at exactly the point where Division 296 begins to bite. Understanding it helps trustees ask the right questions.

What tax-effect accounting is

Tax-effect accounting recognises not just the tax a fund owes now, but the tax it is expected to pay or save in the future because of differences between the accounting and tax treatment of its assets. The most common example in an SMSF is an asset that has risen in value but has not been sold: there is an unrealised gain, and with it a potential future Capital Gains Tax Liability if the asset is ever sold in the accumulation phase.

A fund that applies tax-effect accounting records a deferred tax liability for that future tax. A fund that does not, and simply accounts for tax as it falls due, will not. Both approaches are seen in practice, and the choice affects the fund's reported net Assets and therefore members' account balances.

How it reaches total super balance

A member's total super balance is essentially their share of the fund's net assets, plus certain other amounts. If the fund books a deferred tax liability for unrealised gains, net assets are lower, and so is each member's reported balance. If it does not, net assets and member balances are higher by the amount of that unrecognised future tax.

Because Division 296 keys off total super balance above the indexed $3 million threshold, a difference in reported balance can change whether a member is over the line, and by how much. For a member sitting close to $3 million, the accounting treatment of deferred tax is not a rounding issue; it can be the difference between an assessment and none.

A clearly hypothetical illustration

Take a hypothetical SMSF with a single member whose account holds assets carrying a large unrealised gain, leaving the reported balance hovering around the threshold. If the fund recognises a deferred tax liability on that gain, the member's total super balance is reduced by the provision, potentially keeping them under $3 million for the year.

If the fund instead ignores deferred tax, the same underlying assets produce a higher reported balance, potentially over the threshold. The economic reality is identical; only the accounting differs. This illustration is not advice, and the figures in any real case need to be worked through properly, but it shows why the treatment matters where Division 296 is in play.

Consistency and defensibility

The point is not that one treatment is a clever way to reduce tax. Accounting policies should be applied consistently and be defensible, and switching methods just to influence a Division 296 result would invite scrutiny. What trustees can reasonably do is understand which approach their fund uses, why, and what it means for reported balances.

Auditors will expect the fund's approach to deferred tax to be consistent from year to year and appropriate to the fund's circumstances. A sudden change, or an approach that does not reflect the fund's real position, is the kind of thing that undermines the credibility of the financial statements the Division 296 calculation relies on.

Realised Earnings still drive the tax

It is worth separating two things. Deferred tax accounting affects the balance figure that decides whether a member is above the threshold. The Division 296 tax itself, in its enacted form, applies to realised earnings, not unrealised gains. So the accounting for unrealised gains influences the threshold test, while the tax that follows is based on what the fund actually realises.

That distinction matters because it means the deferred tax question is about positioning relative to $3 million, not about the amount of Division 296 earnings directly. Both interact, but they are different levers, and conflating them is a common source of confusion among trustees encountering the measure for the first time.

Questions for your accountant

For members near the threshold, a few questions are worth putting to the fund's accountant. Does the fund recognise deferred tax on unrealised gains, and has that approach been consistent? How does that treatment affect my reported total super balance this year? And how does it interact with the optional cost base reset election available for Division 296 purposes?

None of this is a do-it-yourself exercise, and it is general information rather than advice about any particular fund. But asking the questions ensures trustees understand how an accounting policy, largely invisible in ordinary years, can shape their exposure to a tax that begins on 1 July 2026.

The broader lesson is that Division 296 rewards funds that keep their financial records clean, current and internally consistent. Where a member is anywhere near the threshold, the quality of the fund's accounting is no longer just a matter of tidy bookkeeping; it directly shapes a tax outcome. That is a good reason to engage early with the accountant, agree the fund's approach to valuations and deferred tax, and keep the supporting evidence that an auditor, and potentially the ATO, will expect to see behind the numbers.

It is also a reminder that Division 296 is not only a concern for the wealthiest funds. A member whose balance is comfortably below $3 million today can approach it over time through Investment growth and contributions, and because the thresholds are indexed only gradually, more members are likely to encounter the measure in future years. Understanding how the fund's accounting shapes the reported balance is therefore useful preparation even for those not yet affected, so that the levers are familiar well before they matter in practice.

Practical takeaway

The balance that Division 296 measures is an accounting output, and the treatment of deferred tax on unrealised gains can move it. Recognising a deferred tax liability lowers reported member balances; not recognising it raises them, which can matter for a member near the indexed $3 million threshold. Trustees should understand and apply their fund's approach consistently, and ask their Accountant how it affects their total super balance well before an assessment is raised.
