Further guidance on proposed additional 15% tax on earnings on super balances over $3 million from 1 July 2025

Last week, we released a Tax Alert (click here) after the Government announced proposed changes to impose an additional tax of 15% (the additional tax), increasing the original concessional tax rate from 15% to an effective new 30% rate, on earnings on total superannuation balances (TSB) over $3 million.

This measure is proposed to commence on 1 July 2025 and apply to the 2025-2026 financial year onwards.

This week, the Government released further guidance to help explain how the additional tax would be applied to earnings on TSB over $3 million.

The additional tax only applies to the proportion of earnings corresponding to balances above $3 million, and this means that earnings corresponding to funds below $3 million will continue to be taxed at the original concessional tax rate of 15% or less.

What are earnings?

Earnings are calculated with reference to the difference in TSB at the start and end of the financial year, adjusting for withdrawals (added) and contributions (subtracted).

The calculation of earnings includes all notional (unrealised) gains and losses, similar to the way superannuation funds currently calculate members’ interests. The proposed changes intend to treat defined benefit interests in a similar way, however no details are available at this time. We anticipate further details during the consultation process before these proposed changes become legislation.

Negative earnings can be carried forward and offset against any additional tax liabilities assessed in future years. However, it is important to note that any “negative earnings” can only be carried forward, and they can not be carried back to previous years to refund any additional tax liability paid in previous years.

We anticipate this limitation within relation to the “negative earnings” concept will also be debated during the consultation process.

What is your TSB?

An individual’s TSB includes all of their superannuation interests (across multiple superannuation fund accounts) and is not a separate figure for each interest, which means the $3 million threshold will be applied on a per-individual basis and not on a per-account or per-fund basis. TSB includes both pension and accumulation account balances.

The Australian Taxation Office (ATO) currently uses superannuation fund reporting to calculate the total amount that individuals have in the superannuation system, for example to determine whether individuals are eligible to make non-concessional contributions.

How is the additional 15% tax assessed and how is it paid?

These proposed changes are scheduled to commence on 1 July 2025 for the 2025-2026 income year.

The ATO will issue a notice of additional tax directly to individual members, notifying them of their additional tax liability to pay. Individuals will then have the choice of either paying the tax out-of-pocket or from their superannuation funds. Individuals who hold multiple superannuation funds can elect the fund from which the tax is paid.

This additional tax liability notice will be separate from an individual’s personal income tax, similar to the existing Division 293 tax. This means that any tax offsets or franking credits available to the individual on their notice of assessment (for income tax purposes) cannot be applied to reduce any additional tax liability imposed by the ATO.

Practice Update – March 2026

March 2, 2026

$20,000 instant asset write-off extended The Government recently passed legislation to extend the $20,000 instant asset write-off for small businesses by 12 months to 30 June 2026. Taxpayers should note that if their business has an aggregated annual turnover of less than $10 million, they may be able to use the instant asset write-off ( IAWO ) to immediately deduct the business portion of the cost of eligible assets which cost less than $20,000. Eligible assets must basically have been first used (or installed ready for use) between 1 July 2025 and 30 June 2026. The $20,000 limit applies on a per asset basis, so taxpayers can instantly write-off multiple assets. The IAWO can be used for both new and second-hand assets (but some exclusions and limits apply).

Division 296 draft legislation introduced to Parliament Last week the revised Division 296 draft legislation was introduced into Parliament, and some technical amendments have been made after the exposure draft consultation phase. We will explain some particular areas of concern and re-consider some questions we had raised in earlier Tax Alerts on this topic. This draft legislation has been progressing at a rapid pace, and it appears the Government wants to get this legislation finalised as soon as possible, with these Division 296 rules set to apply from 1 July 2026.
