Australia's $1.6B Super Tax Change — How Division 296 Hits Balances Above $3M
Australia has confirmed a $1.6 billion-a-year tax change affecting millions of superannuation accounts.

Treasury estimates ~80,000 Australians are affected. How much will it cost you?

What is Division 296?
Division 296 is Australia's new tax on superannuation earnings for high-balance individuals. From July 1, 2025, super balances above $3 million face an additional 15% tax on earnings attributable to the portion above the threshold—effectively doubling the tax rate from 15% to 30% on that portion. The measure raises an estimated $1.6 billion annually and affects approximately 80,000 Australians.
Earnings are calculated as: closing balance minus opening balance minus net contributions. The proportion of earnings above $3M is (balance − $3M) / balance. The additional 15% tax applies to that proportion of earnings. Unrealised capital gains are included in earnings—a controversial aspect that can create liquidity issues.
The $3 million threshold is not indexed to inflation, so over time more Australians will be pulled into the Division 296 net as balances grow.

How Division 296 Calculates Earnings
Earnings = closing balance − opening balance − net contributions. For the portion above $3M, the proportion is (balance − $3,000,000) / balance. Additional tax = earnings × proportion × 15%.
Example: $4M balance, $200K earnings. Proportion = ($4M − $3M) / $4M = 25%. Earnings above $3M = $200K × 25% = $50K. Division 296 tax = $50K × 15% = $7,500.
Division_296_tax = Earnings_above_3M × 15%
Unrealised gains are included: if your super fund holds shares that appreciate but you haven't sold them, the paper gain is still taxed under Division 296. This can create liquidity pressure—you may need to sell assets to pay tax on gains you haven't realised.
The $3 Million Threshold (Not Indexed)
The $3 million threshold is fixed and does not increase with inflation. In 2025, $3M represents a significant retirement nest egg. In 20 years, with 3% inflation, $3M in today's dollars would be equivalent to ~$5.4M in future dollars—but the threshold stays at $3M. Bracket creep will pull more Australians into Division 296 over time.
Total super balance is measured at 30 June each year. The ATO uses the higher of start-of-year or end-of-year balance in some calculations—so even if you withdraw during the year, you may still be subject to Division 296 if your balance was above $3M at measurement.
Comparison: Current 15% vs Division 296
Under current rules, super earnings are taxed at a flat 15% (or 10% for capital gains from assets held 12+ months). Division 296 adds 15% on the portion of earnings attributable to balances above $3M—so that portion is taxed at 30% total: 15% standard + 15% Division 296.
The calculator shows year-by-year projections with and without Division 296, so you can see the cumulative impact on your retirement nest egg over your remaining working years.
Who Is Affected?
Treasury estimates approximately 80,000 Australians had super balances above $3 million when the measure was announced. This represents about 0.5% of super fund members. Affected individuals include self-funded retirees, high-income professionals, small business owners who have sold businesses into super, and dual-income couples with combined balances (each individual is assessed separately—the $3M threshold applies per person).
SMSF members are affected the same as APRA-regulated fund members. The tax applies regardless of whether you hold assets in an SMSF or industry/retail fund.
Strategies to Manage Division 296
Consider: (1) Contribution splitting with a spouse to keep balances below $3M per person; (2) Pension drawdowns—if you've reached preservation age, drawing down pension income can reduce your balance; (3) Restructuring—hold some assets outside super and compare after-tax returns; (4) Timing of contributions—if near the threshold, you may delay or reduce concessional contributions.
Every situation is unique. Seek advice from a qualified financial adviser—strategies depend on your age, balance, retirement goals, and spouse's situation.
Constitutional Concerns
Some legal commentators have raised constitutional concerns about Division 296, particularly the taxation of unrealised gains. The Commonwealth's taxation power may be tested; the High Court has not yet ruled on Division 296 specifically. The government has indicated it is confident the measure is constitutionally sound.
International Comparison
The UK has a lifetime allowance (now abolished) that taxed pension savings above a threshold. The US 401(k) has no equivalent to Division 296—contributions and earnings grow tax-deferred until withdrawal, with no additional tax on high balances. Australia's approach is relatively unique in taxing super earnings above a threshold while the member is still accumulating.
Impact on SMSF
SMSF members with balances above $3M are subject to Division 296. The ATO will notify funds when a member has a total super balance above $3M and may request information on realised earnings. SMSF trustees should ensure they can provide the necessary data. Division 296 tax can be paid from super (similar to Division 293) or personally by the member.
Timeline and Effective Dates
Division 296 applies from July 1, 2025. The first full financial year affected is 2025-26. Total super balance is measured at 30 June each year. The first Division 296 assessments will be issued in 2026-27. Members can elect to pay the tax from their super fund or personally.
