The ATO has begun issuing the first Division 296 tax assessments. Learn how to manage the cash flow impact of taxing unrealised gains without triggering forced asset sales.

As of 11 August 2026, the Australian Self-Managed Superannuation Fund (SMSF) landscape has entered a new era of tax complexity. The Australian Taxation Office (ATO) has officially commenced issuing the first wave of Division 296 assessments following the conclusion of the 2025-26 financial year. For the approximately 80,000 Australians with total superannuation balances (TSB) exceeding $3 million, this move translates into a significant new tax liability that departs from traditional taxation principles by including unrealised capital gains in its calculation.

Decoding the 'Calculated Earnings' Formula

The primary challenge of Division 296 lies in its departure from the 'realised' tax model. Historically, capital gains tax is only triggered when an asset is sold. Under Division 296, the ATO uses a 'calculated earnings' formula that measures the movement in a member's Total Superannuation Balance from one financial year to the next, adjusted for contributions and withdrawals. This means if a property or share portfolio increases in value on paper, that growth is considered 'earnings' even if no cash has been received by the fund.

The Division 296 Math

The tax applies a 15% rate to the proportion of earnings linked to the balance above $3 million. The formula used is: Earnings = (TSB at 30 June 2026 + Withdrawals - Net Contributions) - TSB at 30 June 2025. This ensures that the tax captures the total economic growth of the member's interest, regardless of whether that growth is reflected in liquid cash flow.

The Liquidity Strain of Unrealised Gains

The most pressing concern for trustees is the 'dry tax' problem. Paying a tax bill on money that is still locked in an asset requires liquid cash reserves. For many high-balance SMSFs, especially those holding significant proportions of Australian equities or property, the 15% additional levy can create a sudden cash flow vacuum. If a fund does not have sufficient liquid assets—such as cash or high-turnover shares—to cover the assessment, it may face a liquidity crisis.

  • Valuation Volatility: A sharp rise in asset valuations during the financial year will result in a larger tax bill, even if market prices drop shortly after the assessment date.
  • Cash Reserve Management: Maintaining higher cash buffers within the SMSF can mitigate the risk of forced sales but may also drag on overall investment performance.
  • Asset Disposal Pressure: Funds with low liquidity may be forced to sell assets in unfavourable market conditions to meet the 15% levy on the excess balance earnings.

Commercial Property: The High-Risk Frontier

Trustees holding commercial property within their SMSFs are arguably the most exposed to Division 296 complications. Commercial real estate is inherently illiquid and subject to periodic valuation updates that can show substantial 'paper gains' in a rising market. Unlike a portfolio of blue-chip shares, a trustee cannot simply sell 'one room' of a warehouse to pay a tax bill. This makes the timing of Division 296 assessments particularly sensitive for property-heavy funds.

Valuation Requirements and Compliance

With the ATO signaling a crackdown on non-arm's length transactions (NALI) and expense reporting in their 2026-27 Compliance Roadmap, ensures that property valuations are performed at market rates and are fully defensible. Incorrect valuations not only risk Division 296 miscalculations but can lead to broader regulatory scrutiny.

Strategic Options for Meeting Tax Liabilities

Managing the impact of Division 296 requires a forward-looking approach to fund liquidity. The legislation provides some flexibility in how the tax is paid, which can be critical for preserving the fund's core investment strategy. Trustees have the option to pay the Division 296 tax liability personally (outside the fund) or to have the fund pay it on their behalf. Paying personally can be a strategic move to keep more capital within the tax-concessional environment of superannuation, provided the individual has the personal cash flow to support it.

Furthermore, portfolio rebalancing may be necessary to ensure that the asset allocation accounts for these annual tax outgoings. This might involve shifting toward assets with higher yield components (dividends and rent) rather than pure capital growth, or establishing a 'tax sinking fund' within the SMSF's cash account. As the first assessments are processed, the focus must remain on maintaining the integrity of the fund's long-term objectives while satisfying these new, annual obligations.

The arrival of Division 296 represents a fundamental shift in how high-value SMSFs must operate. By understanding the 'calculated earnings' mechanism and preparing for the liquidity demands of taxing unrealised gains, trustees can navigate this transition without resorting to the distressed sale of core assets. With the ATO also focusing on digital security and NALI provisions, the administrative and strategic burden on SMSF trustees has never been higher, necessitating a meticulous approach to fund management and cash flow forecasting.
