Division 296, the additional tax on super earnings for high-balance members, passed the Senate on 10 March 2026 and takes effect 1 July 2026. This replaces the earlier timeline uncertainty with a firm implementation date and final design. This article summarises the law as passed, what changed from the drafts, and the planning signals for members at or approaching the thresholds.
What passed
The Treasury Laws Amendment (Building a Stronger and Fairer Super System) Act 2026 implements Division 296 in two tiers, both attached to a member’s Total Super Balance (TSB):
| TSB tranche | Div 296 rate (additional) | Total tax (incl. base 15%) |
|---|---|---|
| Up to $3 million | — | 15% |
| $3 million – $10 million | +15% | 30% |
| Above $10 million | +25% | 40% |
The tax applies only to the realised earnings attributable to the portion of TSB above each threshold. Dividends, interest, rent, and realised capital gains net of realised losses are in scope. Unrealised capital gains are excluded — a material change from the 2023–2025 exposure draft, which taxed notional earnings computed from opening-vs-closing balance differences. Capital gains accrued before 1 July 2025 are also grandfathered out.
Both thresholds are CPI-indexed: the $3 million threshold rises in $150,000 steps, and the $10 million threshold in $500,000 steps.
First assessment year
- 30 June 2026: first TSB test date (transitional — the 2026-27 first-year rule uses the closing balance only, not an opening-vs-closing comparison).
- 2026-27 financial year: ATO issues the first Div 296 assessments.
- Payment: members can elect to pay from super or personal funds within 84 days of the assessment.
Who is affected
The ATO estimates fewer than 1% of Australians have super balances above $3 million. For the vast majority of workers and retirees, Division 296 is not relevant to their own position. The members most exposed are:
- SMSF members with large property or business real property holdings — liquidity planning matters because Div 296 is payable in cash even if the underlying realised earnings remain inside the fund.
- Account-based pension holders approaching or above the $3M threshold after the transfer balance cap was reached.
- Defined benefit scheme members — a separate commensurate methodology applies; members should seek specific advice on how notional earnings are computed for their interest.
- SMSF members with sizeable unlisted or illiquid assets — the switch to realised-only earnings reduces the worst-case outcomes of the original draft, but realisation decisions still affect timing of the tax liability.
Planning considerations
Liquidity
Confirm the fund can meet an annual Div 296 liability without forcing asset sales. SMSFs holding commercial property or business real property may need to hold cash reserves or plan orderly disposals.
Contribution timing
Non-concessional contributions push a balance closer to or across the $3M threshold. Members within $200k of the threshold should stress-test the incremental Div 296 cost against the benefit of additional contributions.
Withdrawals
Members above the threshold and over 60 may consider withdrawals to bring the balance below $3M — pension-phase withdrawals are generally tax-free at that age. The trade-off is forgoing future concessionally-taxed earnings inside the fund; run the numbers on a 10–20 year horizon before acting.
Realisation timing
With the realised-earnings methodology, the year of disposal determines when Div 296 is triggered on a capital gain. Deferring sales can defer liability; accelerating sales can use up the grandfathered pre-1-July-2025 base. Coordinate with the fund’s capital-gain position and the member’s broader tax situation.
Record-keeping
Funds must be able to distinguish pre-1-July-2025 gains (grandfathered) from post-2025 gains. Cost-base documentation, asset acquisition dates, and pre-2025 market valuations are now material inputs to the Div 296 calculation for funds with long-held assets.
Defined benefit members
The commensurate methodology for defined benefit interests is set out in the Act and supporting regulations. Members should seek specific advice on how their notional earnings are computed and how the tax is debited.
Impact example
A member with a $15M TSB and $900,000 of realised earnings in 2026-27:
- $3M–$10M tranche = 7/15 of TSB → $420,000 assessable × 15% = $63,000
- Above $10M tranche = 5/15 of TSB → $300,000 assessable × 25% = $75,000
- Total Div 296 tax = $138,000
Effective Div 296 rate on the full $900k = 15.3%. Base super contributions tax (15%) remains separate. For a member on the top personal marginal rate of 47%, the same $720,000 of assessable earnings would cost $338,400 if held outside super — so super remains strongly tax-advantaged even at the 40% combined top rate.

What to monitor
- ATO practical compliance guidance — rulings and determinations on the commensurate methodology, pre-1-July-2025 grandfathering mechanics, and interaction with the transfer balance cap and retirement-phase interests.
- CPI movement — first threshold indexation could move the $3M threshold upward from 2027-28 onwards.
- SMSF trustee obligations — reporting and valuation requirements for calculating attributable realised earnings.
- Future policy reviews — Division 296 review mechanisms are included in the Act; monitor Treasury communications for any post-implementation review.
