The long-awaited Division 296 tax has now passed both houses of Parliament and received Royal assent, becoming law under the Treasury Laws Amendment (Building a Stronger and Fairer Super System) Bill 2026.

While media coverage has focused on the so-called ‘$3m super tax’, the rules are more nuanced in practice. Division 296 affects certain high-balance super accounts, and the way the tax is calculated depends on several factors. This alert explains who is impacted, how the tax operates, and the key practical issues that are emerging.

Who is affected by Division 296

Division 296 applies to individuals whose total superannuation balance (TSB) exceeds $3m.

There are two thresholds:

$3m to $10m

• An additional 15 percent tax applies to the proportion of super earnings attributable to balances above $3m.

Over $10m

• A further 10 percent tax applies, resulting in a total additional tax of 25 percent on the relevant portion of earnings.

Both thresholds will be indexed to CPI, using incremental increases of $150,000 for the $3m threshold and $500,000 for the $10m threshold.

If your total super balance is below $3m, Division 296 will not apply. Division 296 will only apply if your TSB exceeds the relevant threshold.

What is actually being taxed

Division 296 does not tax:

• your total super balance
• your contributions
• withdrawals from super.

Instead, it applies to superannuation earnings, based on the proportion of your balance that exceeds the relevant threshold.

Super funds will continue to pay their usual tax on earnings, generally 15 percent. Division 296 operates at the individual level and effectively increases the tax rate on super earnings attributable to very large balances.

In broad terms, this means:

• earnings on balances above $3m may be taxed at up to 30 percent in total
• earnings on balances above $10m may be taxed at up to 40 percent in total.

An example of how Division 296 applies

Facts

• Total superannuation balance at 30 June 2027: $5m
• Superannuation earnings for the year: $400,000
• Member is in accumulation phase
• Balance exceeds $3m but is below $10m

Step 1: Determine the proportion of the balance above $3m

• Amount above $3m: $2m (TSB $5m – $3m threshold)
• Proportion above threshold: $2m ÷ $5m = 40 percent

Step 2: Apply this proportion to super earnings

• Earnings subject to Division 296: $400,000 × 40 percent = $160,000

Step 3: Apply the additional Division 296 tax

• Division 296 tax rate: 15 percent (between $3m and $10m only)
• Division 296 tax payable: $160,000 × 15 percent = $24,000

Total tax outcome

• The super fund continues to pay its normal tax on earnings
• The individual receives a separate Division 296 assessment of $24,000
• The individual can pay this personally or elect to release funds from super

This example illustrates that Division 296 does not apply to all earnings, only the portion attributable to the balance above $3m.

How earnings are calculated

Following industry feedback, the final legislation does not tax unrealised capital gains.

Instead, earnings are calculated using a realised earnings approach. Super funds will report realised, attributable earnings for affected members to the Australian Taxation Office (ATO) using approved methodologies.

Key points:

• Unrealised gains are excluded.
• Contributions are adjusted for.
• Special rules apply to pension phase income and defined benefit interests.

This change significantly reduces volatility risk compared to the original proposal.

How the balance threshold is tested

From the 2026–27 financial year onwards, an individual’s TSB will be measured at:

• the start of the financial year
• the end of the financial year.

The higher of these two balances will be used to determine whether Division 296 applies.

A transitional rule applies in the first year, where only the closing balance at 30 June 2027 is tested. This may create limited planning opportunities for individuals who have already met a condition of release.

Paying the Division 296 tax

The ATO issues the assessment to the individual affected.

Within 84 days, the individual can either:

• pay the tax from personal funds
• elect to release money from super, similar to the process under Division 293.

Key practical issues to be aware of

We are already seeing a number of recurring themes for impacted clients:

• Asset valuations matter more than ever, particularly for self-managed superannuation funds (SMSFs) holding property or unlisted investments.
• Capital gains tax (CGT) election will be available for SMSF’s assets at 30 June 2026 for Division 296 purposes only. The election is optional, must be applied to all CGT assets held directly by the fund, is irrevocable, and must be made by the due date of the fund’s 2026-27 tax return.
• Liquidity planning is critical, especially where super assets are illiquid.
• Spouse balance disparities can increase exposure over time.
• Defined benefit members will be subject to modified rules, with tax typically payable on retirement rather than annually.

What you should do now

If your total super balance is approaching or already exceeds $3m, consider:

• reviewing current and projected super balances
• ensuring valuation processes are robust
• modelling future earnings and potential Division 296 exposure
• revisiting contribution, pension, and estate planning strategies.

The post Division 296 tax has passed parliament and what it means for large super balances appeared first on SW Accountants & Advisors.

The government has confirmed several important changes to the Division 296 proposed superannuation tax reforms. The updated measures aim to improve fairness while reducing the administrative burden and unintended impacts of the original proposal.

We’ve summarised the key updates and the practical steps you can take to prepare.

Key changes announced

Tax to apply only to realised earnings

The government has scrapped its plan to tax unrealised capital gains on super balances above $3m. The revised proposal will now apply only to future realised earnings, addressing major concerns about fairness and liquidity raised by tax professionals and fund managers.

Indexation of the $3m threshold

The $3m threshold will now be indexed in line with other superannuation limits. This change ensures that inflation and market growth do not gradually push more Australians into the higher tax bracket over time.

New $10m tier introduced

A second tax threshold of $10m will be introduced which will create a more progressive structure. Earnings between $3m and $10m will be taxed at 30%, while earnings above $10m will attract a 40% rate. Both thresholds will be indexed.

Implementation delayed until 1 July 2026

The introduction of the new tax has been delayed by one year, giving super funds, advisors, and affected members additional time to prepare. This adjustment also reduces the short-term impact on the federal budget.

Defined benefit pensions to be included

The revised design will ensure the new tax also applies to defined benefit pensions, maintaining consistency and fairness across different types of superannuation interests.

Boost for low-income earners

The Low Income Super Tax Offset (LISTO) will rise from $500 to $810, and the income eligibility threshold will increase from $37,000 to $45,000 from 1 July 2027. These changes will benefit an estimated 1.3m Australians, particularly women and part-time workers, helping them grow stronger retirement savings.

Budget impact of the reforms

Treasurer Chalmers confirmed the refinements will cost around $4.2bn over the forward estimates, mainly due to the one-year delay in implementation. He said the reforms “maintain the concessional treatment of superannuation, but ensure it is provided in a more equitable and sustainable way.”
