Division 296: What the new $3 Million super tax could mean for you
From 1 July 2026, new superannuation tax rules known as Division 296 are set to apply to Australians with larger super balances.
While the headlines focus on a “tax on super balances above $3 million”, the reality is far more complex — and for many individuals and families with significant retirement savings, understanding how the rules work will be important.
What is Division 296?
Division 296 introduces an additional tax on certain superannuation earnings once an individual’s Total Superannuation Balance (TSB) exceeds specific thresholds.
The key thresholds are:
- $3 million
- $10 million
Where a balance exceeds $3 million, a proportion of super earnings may attract an additional 15% tax.
For balances above $10 million, a further 10% tax may apply to earnings attributable to amounts above that threshold.
Importantly, this is not a tax paid by the super fund itself. Instead, it is a personal tax liability assessed directly to the individual. The amount can generally be paid personally, from superannuation, or using a combination of both.
How is the tax calculated?
One of the biggest misunderstandings around Division 296 is that the tax is simply based on changes in your super balance.
That’s not the case.
The legislation uses a specific formula to calculate “earnings”, beginning with the fund’s taxable income and then making a range of adjustments.
The calculation can include:
- Earnings in both accumulation and pension phase
- Realised investment gains and income
- Earnings on pension assets that are normally tax-free within super
- Adjustments for contributions, which are excluded from earnings calculations
Once earnings are determined, only the proportion relating to balances above the relevant thresholds is subject to the additional tax.
Why this matters
Although the measure will only impact individuals with larger super balances, the rules are highly technical and may affect long-term retirement planning strategies.
For some people, this may influence:
- Contribution strategies
- Pension structures
- Investment decisions inside super
- Estate planning considerations
- Whether certain assets are best held inside or outside superannuation
As with many superannuation changes, the impact will depend heavily on individual circumstances.
What should you do?
At this stage, there may not b e a need for immediate action — however, understanding your current super position and future projections is important.
If your superannuation balance is approaching or exceeds the proposed thresholds, now is a good time to review your strategy and consider how the new rules may affect your long-term plans.
