# Navigating Division 296: Australia's New $3 Million Superannuation Tax
Australia's superannuation system has long been a cornerstone of retirement planning, offering significant tax concessions to encourage self-funded retirement. However, as the system matures and superannuation balances grow, the government periodically reviews its sustainability and equity. The introduction of Division 296 represents one of the most significant changes in recent years, targeting high-balance superannuation accounts with additional tax obligations.
What is Division 296?
Division 296 is a new provision in Australia's Income Tax Assessment Act 1997 that introduces an additional 15% tax on superannuation earnings attributable to superannuation balances exceeding $3 million. Passed into law in March 2026, this measure was designed to improve the fairness of Australia's superannuation system by ensuring that those with very large super balances contribute more.
The key distinction of Division 296 is that it taxes earnings — not contributions or balances directly. If your superannuation fund earns investment returns on the portion of your balance above the $3 million threshold, those earnings may be subject to this extra tax. For balances exceeding $10 million, an additional 10% tax applies to earnings above that higher threshold, bringing the total marginal rate on those earnings to 25% (15% standard plus 10% additional).
Unlike the existing 15% contributions tax that applies to concessional contributions, Division 296 operates on the earnings side. This means the tax is calculated based on the notional earnings allocated to excess balances, as determined by the ATO (ATO guidelines) through a complex methodology outlined in the legislation.
Who Does It Affect?
Division 296 affects a relatively small subset of Australian superannuation fund members. The ATO estimates that approximately 80,000 individuals — less than 1% of the total superannuation membership — will be impacted by this measure. These are predominantly high-wealth Australians with superannuation balances exceeding $3 million at the end of a financial year.
It's important to note that the $3 million threshold applies to your total superannuation balance across all your superannuation accounts, including accumulation and retirement phase accounts. If you have multiple accounts, they are combined for the purposes of determining whether the threshold is exceeded.
Most Australians with superannuation balances below $3 million will not be affected by Division 296 at all. The additional tax is specifically designed to target those with substantial superannuation wealth, and the majority of retirees will never need to consider this provision in their tax planning.
The measure does not distinguish between industry funds, retail funds, or self-managed superannuation funds (SMSFs). All superannuation entities are subject to the same rules, and the tax is applied at the individual level based on each member's share of earnings above the threshold.
How Is It Calculated?
Division 296 introduces a complex calculation methodology that determines the "excess earnings" subject to the additional tax. The ATO uses a specific formula to attribute a portion of a fund's total earnings to each member, based on their share of the total superannuation balance above the $3 million threshold.
The calculation involves several steps. First, the fund determines its total earnings for the financial year, which includes net investment income, capital gains, and other assessable income. Second, the ATO calculates each member's "proportional share" of earnings above the threshold by comparing their balance to the total balances of all members above $3 million. Third, the excess earnings amount is multiplied by 15% (or 25% for earnings above $10 million) to determine the additional tax liability.
Importantly, Division 296 operates independently from — and in addition to — the existing taxes that apply within the superannuation system, including the 15% tax on investment earnings within accumulation accounts. The additional tax is levied on top of these existing obligations.
Key Dates and Timeline
Division 296 became law in March 2026, following an extended consultation process that began with the original announcement in the 2021-22 Federal Budget. The legislation was refined through multiple exposure drafts and parliamentary inquiries before finally passing both houses of Parliament.
The first assessment year for Division 296 purposes will be the 2026-27 financial year. This means that excess earnings generated during the 2026-27 financial year will be calculated and the additional tax will first appear in tax assessments for that year. The payment date for any Division 296 tax liability will align with the standard income tax assessment cycle, typically due by the instalment dates or final due date for the individual's tax return.
How to Prepare Before 30 June
While the first Division 296 assessments will not appear until the 2026-27 financial year, there are several strategies individuals with superannuation balances approaching or exceeding $3 million may wish to consider in their overall financial planning.
One approach involves reviewing your total superannuation balance and projecting whether you are likely to exceed the $3 million threshold in future years. If your balance is close to the threshold, careful planning around contribution timing and investment strategy may help manage your exposure to the new tax.
Another consideration is the timing of contributions. Concessional contributions — which include employer contributions and salary sacrifice arrangements — continue to be taxed at 15% up to the existing contribution caps. For individuals with very large balances, ensuring that contributions are optimised within the caps remains important, but bunching contributions in certain years to maximise the tax-effectiveness of contributions may warrant consideration in the context of overall wealth management.
Transition-to-retirement strategies may also warrant review. Some individuals use transition-to-retirement pensions to boost savings while continuing to work, but the interaction between these strategies and Division 296 should be carefully evaluated.
Estate planning implications also merit attention. The interaction between Division 296 and the treatment of superannuation death benefits requires careful analysis, particularly for individuals with large balances who may be considering how to structure the distribution of their superannuation upon death.
