30% Tax on Super Earnings Above $3m

On 28 February 2023, the Government announced from 1 July 2025 a 30% concessional tax rate will be applied to future earnings for superannuation balances above $3 million. A significant jump of 15%. The Treasury has now released draft legislation to enact the Government’s plan to increase the tax rate on earnings on superannuation balances above $3m.

This is the final step before the legislation is introduced into Parliament and a step closer to reality. The draft legislation appears largely unchanged from the Government’s original announcement.

How does it work?

The proposed calculation aims to capture growth in total super balance (TSB) over the financial year allowing for contributions (including insurance proceeds) and withdrawals. This method captures both realised and unrealised gains, enabling negative earnings to be carried forward and offset against future years.

The ATO will perform the calculation for the tax on earnings. TSBs in excess of $3 million will be tested for the first time on 30 June 2026 with the first notice of assessment expected to be issued to those impacted in the 2026-27 financial year.

The Treasury’s media release from 28 February 2023, gives a fact sheet that explains in more detail.

An example from the factsheet shows how the aim is to apply a further 15% tax on the proportion of the “earnings” of the fund that relates to an account balance in excess of $3 million:

Balance exceeding $3 million

- Warren is 52 with $4 million in superannuation at 30 June 2025. He makes no contributions or withdrawals. By 30 June 2026 his balance has grown to $4.5 million.

- This means Warren’s calculated earnings are:

$4.5 million – $4 million = $500,000

- His proportion of earnings corresponding to funds above $3 million is:

($4.5 million – $3 million) ÷ $4.5 million = 33%

- Therefore, his tax liability for 2025-26 is:

15% × $500,000 × 33% = $24,750

This tax is levied on Warren and is in addition to taxes currently payable by the superannuation fund on the fund’s income. Due to the proportional calculation, the more you have in superannuation over $3 million, the greater impact the new tax will have on you. This will be particularly challenging when unrealised gains are taxed, as you may not have the cash to pay the additional tax.

Planning ahead

It is true that with more than two years before this proposal is due to start, a lot can change. However, it pays to plan ahead of time.

From a planning perspective, for those with superannuation balances close to or above $3m, it will be important to explore the implications to your personal situation – there is no one size fits all strategy here and what is best for you will depend on your circumstances. Superannuation, even with the increased tax, remains a tax efficient vehicle.

Ruddicks staff have recently undertaken comprehensive training on the new proposals.
