A major shake-up is on the horizon for Australian superannuation, and if you have a significant balance, you need to pay attention. The Federal Government is introducing Division 296 tax, a new 15% charge on earnings for individuals with a Total Superannuation Balance (TSB) over $3 million.

This isn’t just a minor adjustment; it’s a fundamental change to how high-balance super funds are taxed, officially kicking in on 1 July 2025. Most importantly, it targets not just realised investment returns but also controversial unrealised gains, making proactive planning essential for SMSF members and high-net-worth individuals.

What is Division 296 Tax in Australia?

The Division 296 tax is a new 15% tax on the earnings of superannuation balances exceeding $3 million. This tax applies to the investment growth attributable to the portion of your balance over the threshold. It is designed to make superannuation tax concessions more equitable and is scheduled to start from 1 July 2025.

How Division 296 Works (Simple Explanation)

In plain English, the Division 296 rule adds an extra layer of tax for individuals with large superannuation balances. Currently, earnings inside super are generally taxed at a concessional rate of 15% (or 0% in retirement phase). This new measure introduces an additional 15% tax on earnings for balances over the $3 million mark, bringing the total tax on those specific earnings to 30%.

Crucially, the tax applies to a broad definition of “earnings,” which is calculated based on the change in your Total Superannuation Balance (TSB) year-on-year. This means the calculation includes not only realised profits from selling assets but may also include unrealised “paper” gains from assets that have increased in value but have not yet been sold. This is a significant departure from standard Australian tax principles.

Who Will Be Affected by Division 296 Tax?

While the government estimates it will impact around 80,000 Australians initially, the number is expected to grow as investment returns and contributions push more people over the threshold. The individuals most likely to be affected include:

• SMSF Members: Trustees of self-managed super fund rules in Australia with large, illiquid assets like property or private equity are particularly exposed.
• High-Net-Worth Individuals: Anyone whose Total Superannuation Balance across all funds (including industry and retail funds) is approaching or exceeds $3 million.
• Individuals with Large Super Balances: This includes those in both accumulation and retirement (pension) phases. The tax applies regardless of your age or work status.

How Division 296 Is Calculated (Example)

To understand the real-world impact, let’s look at a practical example. The ATO uses a specific formula to determine your tax liability.

Personal Example:

Meet Sarah, an SMSF trustee. Here’s a snapshot of her super balance for the 2025-26 financial year:

• Total Super Balance on 1 July 2025: $4,000,000
• Total Super Balance on 30 June 2026: $4,500,000
• Net Contributions (Contributions minus Withdrawals): $0

1. Calculate Earnings: The ATO calculates “notional earnings” by taking the change in her balance, adjusted for contributions and withdrawals.

• Earnings = ($4,500,000 – $4,000,000) = $500,000

2. Determine the Taxable Portion: Next, we find the proportion of her balance that is over the $3 million threshold.

• Proportion = ($4,500,000 – $3,000,000) / $4,500,000 = 33.33%

3. Calculate the Potential Tax Impact: The 15% tax rate is applied to the taxable part of her earnings.

• Taxable Earnings = $500,000 x 33.33% = $166,650
• Potential Tax = $166,650 x 15% = $24,997.50

This $24,997.50 is a personal tax liability for Sarah, which she can pay from her own funds or elect to have released from her super account.

Why Division 296 Is Controversial

The primary point of debate is the decision to tax unrealised gains. Traditionally, capital gains tax is only payable when an asset is sold and a profit is realised. Division 296 breaks from this principle by taxing “paper profits”—increases in asset value that have not yet been converted to cash.

This creates a significant liquidity problem. An SMSF holding a commercial property that increases in value by $500,000 could trigger a tax bill for its members, even though no cash has been received. This forces members to find real money to pay tax on a theoretical gain, potentially forcing the premature sale of high-performing assets. This is why the super tax on unrealised gains has caused so much concern.

How SMSF Investors May Be Impacted

SMSF investors are uniquely exposed due to their common investment strategies. The implications include:

• Pressure on Illiquid Assets: Funds heavily invested in property, unlisted business shares, or agricultural assets will face challenges in generating the cash flow needed to pay the tax. This could force asset sales at inopportune times, disrupting long-term strategies.
• Increased Administrative Burden: Valuing illiquid assets annually becomes even more critical and contentious, as these valuations will directly impact a member’s personal tax assessment.
• Strategic Re-evaluation: Trustees will need to reconsider their investment mix, perhaps shifting towards more liquid assets to manage potential tax liabilities.

Strategies to Consider Before Division 296 Starts

With the $3 million super tax commencing on 1 July 2025, proactive planning is crucial. Waiting is not a viable strategy. Consider discussing the following with a professional adviser:

1. Reviewing Super Balance Levels: Understand your current TSB and project its growth. For couples, exploring strategies to equalise balances can be effective, as the $3 million threshold applies to each individual.
2. Diversification and Liquidity: Assess your portfolio’s liquidity. You may need to rebalance your asset allocation to ensure you have sufficient cash or liquid assets (like listed shares) to meet potential tax obligations without being forced to sell property or other illiquid holdings.
3. Estate Planning Considerations: This tax will erode large super balances over time, impacting their effectiveness as an estate planning tool. It’s vital to review your will and overall wealth transfer strategy to ensure it still aligns with your goals.
4. Seek Professional Tax Advice: The rules are complex, and the consequences of inaction are significant. A tailored plan from a tax expert can help you navigate these SMSF tax changes and protect your retirement savings. For more details straight from the source, you can review the ATO’s official guidance.

Key Questions Australians Are Asking

Here are quick answers to some of the most common questions about the Division 296 tax explained.

• Will Division 296 apply to unrealised gains? Yes. The calculation is based on the movement in your Total Superannuation Balance, which includes unrealised “paper” gains on assets that have increased in value but have not been sold.
• Does it apply to industry funds and SMSFs? Yes. The tax applies to an individual’s Total Superannuation Balance, regardless of whether the funds are held in an SMSF, industry fund, retail fund, or a combination.
• When will Division 296 start? The tax applies to earnings from the 2025-26 financial year onwards. The first tax assessments from the ATO are expected to be issued after the end of that financial year, likely in mid-2027.
• How will the ATO calculate earnings? The ATO will use a specific formula: Earnings = (Current Year TSB – Previous Year TSB) – Net Contributions + Withdrawals. This formula is designed to capture the total growth of your super balance, including both realised and unrealised gains.

Conclusion

The introduction of the Division 296 tax in Australia marks a significant shift in the superannuation landscape. It moves away from the traditional “set and forget” approach, demanding active and strategic management for anyone with a balance near or above the $3 million threshold.

The inclusion of unrealised gains creates genuine challenges, particularly for SMSFs holding illiquid assets. However, with proactive planning, it is possible to mitigate the impact. Reviewing your investment strategy, considering balance equalisation, and updating your estate plan are essential first steps.

The most important action is to seek authoritative, professional advice. A tailored strategy will ensure you are prepared for these changes, protecting the wealth you have worked hard to build for your retirement.
