How to Navigate Australia’s New Superannuation Tax Thresholds for High Balances

Background

Australia’s government has overhauled its proposed superannuation tax changes originally introduced in 2023. Under the revised plan announced in mid-October 2025:

• Unrealised capital gains will no longer be taxed—only gains realized when assets are sold will be taxable. (news.com.au)
• New thresholds will apply: balances between A$3 million and A$10 million will be taxed at 30%, while balances exceeding A$10 million will face a 40% tax rate on earnings above those levels. Both thresholds will be indexed for inflation. (reuters.com)
• These changes will take effect from 1 July 2026, pending successful passage through Parliament. (reuters.com)

Implications & Who’s Affected

• Only a very small portion of super members are likely to be impacted—currently about 0.5% of super accounts are over the A$3 million mark. (reuters.com)
• Without indexation, more people could cross the thresholds over time—hence the government’s inclusion of inflation adjustments. (news.com.au)
• Lower and middle super balances remain unaffected; earners with super balances well below the thresholds will see no change. But thresholds, once legislated, become a planning consideration.

Planning Actions You Should Take Now

1. Estimate your super balance trajectory — project fund growth and consider if your balance might cross A$3 million or A$10 million in future years.
2. Review investment mix and contribution strategies — high-growth assets generate returns more likely to trigger higher-rate taxes on earnings; smoothing growth or timing contributions may help.
3. Defer or time the realization of gains — since only realized capital gains post-sale are taxed, managing when you sell becomes critical.
4. Consult a financial advisor or tax specialist to assess potential impact based on your income, super balance, and retirement timeline.

Practical Example

Jane has A$2.8 million in her super as of 30 June 2025. She expects it to grow to A$3.1 million by June 2026. Under the new rules:

• Earnings on the excess A$100,000 in the 2025-26 year will be taxed at 30%, when in prior rules no extra tax applies until crossing A$3 million.
• If she balances just under A$3 million by that date, she avoids higher tax. Paying attention to fund performance or withdrawing or consolidating may be helpful.

Key Takeaways

• These changes only affect high super balances, so most Australians won’t see any new costs.
• Timing—of realization of gains, of contributions, of balance projections—matters now more than ever.
• Keep an eye on confirmed legislation to see if any further details shift before enforcement.
• If you expect to be close to thresholds, proactively revisit your strategy with advice.

Stay informed, plan early, and always verify how new laws apply to you once enacted.
