The Australian Government is proposing a new tax measure, known as Division 296, which will be aimed at individuals with superannuation balances exceeding $3 million. Whilst this is not law yet and is still being debated in the Senate, it is set to commence on 1 July 2025. The tax introduces an additional levy of 15% on earnings associated with the portion of superannuation balances above the $3 million threshold. This is in addition to the existing 15% on super earnings, effectively doubling the tax rate to 30% for earnings attributable to the excess amount.

Key Features of Division 296:
Applicability: This tax targets individuals whose Total Superannuation Balance (TSB) exceeds the $3 million at the end of a financial year.
Earnings Calculation: It includes both realised and unrealised gains, meaning increases in asset values are tax even if they are not sold.
Threshold: The $3 million cap is not indexed, hence this will potentially affect more individuals over time due to inflation.
Payment options: Individuals can choose to pay the liability personally or release funds from their superannuation accounts.
Calculating the Division 296 Tax:
To determine the Division 296 tax liability, the following steps need to be taken:
Calculate Earnings: Earnings = (TSB at end of financial year + Withdrawals – Net Contributions) – TSB at start of financial year.
Determine Proportion of Earnings Attributed to Balance of $3 Million:
Proportion = (TSB at end of financial year – $3 million) / TSB at end of financial year.
Calculate Tax Liability:
Tax = 15% × Earnings × Proportion
Example Calculation:
Consider an individual with the following superannuation:
TSB on 30 June 2026: $4,300,000
TSB on 30 June 2025: $4,000,000
Contributions during the year: $30,000
Withdrawals during the year: $80,000
Step 1. Calculate Earnings
Earnings = ($4,300,000 + $80,000 – $30,000) – $4,000,000 = $350,000
Step 2. Determine Proportion Attributable to Balance over $3 Million
Proportion = ($4,300,000 – $3,000,000) / $4,300,000 ≈ 30.23%
Step 3. Calculate Tax Liability
Tax = 15% × $350,000 × 30.23% ≈ $15,870.75
Therefore, the individual would incur an additional tax liability of approximately $15,870.75 under Division 296 for the 2025-2026 financial year if this proposal were to go ahead in its current form.
Some Considerations:
The inclusion of unrealised gains means that individuals may face tax liabilities on increases in asset values without actual income or gain realisation.
The lack of indexation on the $3 million threshold could lead to more individuals being affected over time due to inflation and investment growth.
For Defined Benefit Funds, these schemes have specific valuation rules. Members of these style of funds may defer tax payment until retirement.
