Division 296 is often described as a tax on large Superannuation balances, but the way an SMSF records and reports its financial information helps determine the figures that feed into the calculation.

From 1 July 2026, the enacted measure applies additional tax to certain Earnings attributable to portions of total superannuation balances above relevant thresholds. For SMSFs, where trustees and their accountants manage the underlying records, the accuracy and timing of financial information becomes increasingly important.

Accurate accounting does not change the rules, but it helps ensure reported balances and earnings reflect the fund’s actual position.

What Division 296 taxes

Division 296 does not directly tax the superannuation balance itself.

Instead, it applies an additional tax on the share of earnings attributable to the portion of an individual’s total superannuation balance above $3 million. A further additional tax applies to the portion above $10 million.

The thresholds are subject to indexation over time.

The final legislation differs from the original proposal because it applies to realised earnings rather than unrealised capital gains.

This means the calculation focuses on earnings that are recognised under the enacted rules rather than simply measuring changes in the value of Assets that have not been sold.

How the number is built

A member’s total superannuation balance is calculated using information from their superannuation interests, including their SMSF balance.

For an SMSF, this balance is influenced by information contained in the fund’s financial statements, including:

  • asset valuations;
  • income recorded;
  • expenses;
  • tax provisions;
  • allocation of earnings between members.

Because Division 296 applies only above certain thresholds, differences in reported balances may affect whether a member is impacted and the extent of any additional tax.

Two SMSFs holding similar assets could potentially report different balances depending on valuation timing, accounting treatment and how financial information is prepared.

Where accounting settings matter

Several routine accounting decisions can become more significant for members near the relevant thresholds.

Factors such as when a fund realises capital gains, how earnings are allocated between members and how liabilities are recognised can influence reported financial outcomes.

For example, the timing of a realised gain may affect which financial year it is included in for reporting purposes.

This does not mean trustees can manipulate outcomes. Deliberate arrangements designed to avoid tax obligations may create separate compliance issues.

The key point is that normal accounting decisions, when applied correctly and consistently, can have broader implications because reported figures now interact with Division 296 calculations.

The cost base reset election

The enacted Division 296 framework includes an optional transitional election relating to certain directly held Capital Gains Tax assets.

The election allows eligible funds to reset the cost base of selected CGT assets to their Market Value at 30 June 2026 for Division 296 calculation purposes.

The election has specific conditions:

  • it is optional;
  • it is generally irrevocable once made;
  • it applies to eligible assets as a group rather than individual selections;
  • it must be made by the relevant deadline.

The reset applies only for Division 296 purposes. It does not change the ordinary income tax cost base of the assets.

Whether the election is beneficial depends on the fund’s asset mix, unrealised gains and future plans. Trustees should assess the potential outcomes carefully with appropriate advisers rather than assuming the election will produce a particular result.

Getting the records right

For members who may be affected by Division 296, accurate and current records become increasingly important.

Trustees should ensure:

  • asset valuations are properly supported;
  • earnings are allocated correctly;
  • realised transactions are documented;
  • financial records accurately reflect the fund’s position.

Errors that previously resulted in small reporting differences may have greater consequences if they affect whether a member crosses a relevant threshold.

For members approaching the threshold, discussing potential outcomes with accountants and advisers before year-end can help identify issues early.

A note on timing realisations

Consider a hypothetical SMSF member whose total superannuation balance is close to the Division 296 threshold and who holds shares with significant unrealised gains.

If the shares are sold, the timing of that realisation may affect which financial year the realised earnings are recognised in.

However, this does not mean transactions should be structured solely to avoid tax. Anti-avoidance rules and other compliance obligations continue to apply.

The point is that Investment decisions that were previously considered only from an investment perspective may now also have a Division 296 reporting consideration.

The same principle applies to assets that are difficult to value, such as property or unlisted investments. Unsupported or outdated valuations can affect reported balances and create questions during audit.

Maintaining consistent valuation practices supported by evidence remains an important part of SMSF governance.

Practical takeaway

Division 296 increases the importance of understanding how SMSF accounting information flows into tax calculations.

For members near relevant thresholds, areas such as valuations, realised earnings, member allocations and transitional elections may require closer attention.

Accurate records, timely reviews and appropriate professional guidance can help trustees understand how the rules apply to their own circumstances before the first assessments are issued.
