Superannuation Strategies for High-Income Earners in Australia
For high-income earners, superannuation can be one of the most effective ways to build long-term wealth and prepare for retirement. However, higher earnings can also introduce additional tax obligations, contribution restrictions and more complex financial planning decisions.
Making the most of your superannuation isn't simply about contributing more. It requires an understanding of contribution caps, tax implications, investment strategies and how super fits into your broader financial position.
Whether you're a senior executive, medical professional, business owner or established professional, here are eight superannuation strategies worth considering to help you manage tax obligations and build retirement wealth.
1. Maximise Your Concessional Superannuation Contributions
Concessional contributions are generally contributions made to superannuation from before-tax income. They include compulsory employer contributions, salary sacrifice arrangements and personal contributions for which you claim a tax deduction.
These contributions are generally taxed at 15% within your super fund, rather than at your marginal income tax rate, although additional tax may apply to high-income earners.
For the 2026–27 financial year, the concessional contributions cap is $32,500 per person, including employer contributions.
For high-income earners, maximising concessional contributions may help reduce personal income tax while increasing retirement savings.
However, it's important to account for the superannuation contributions your employer already makes.
For example, if your employer contributes $26,000 during the financial year, you may have $6,500 of the standard concessional cap remaining for additional contributions, assuming you have no other concessional contributions and your cap has not been affected by other circumstances.
A carefully planned salary sacrifice arrangement or deductible personal contribution may help you make use of this remaining allowance.
What to consider: Review your total contributions throughout the financial year, particularly if you receive bonuses, change employers or have more than one source of employment income.
2. Take Advantage of Unused Concessional Contribution Caps
If you haven't maximised your concessional contributions in previous years, you may be eligible to make additional contributions using the carry-forward rules.
These rules allow eligible individuals to use unused concessional contribution cap amounts from the previous five financial years.
To qualify, your total superannuation balance must generally have been less than $500,000 at 30 June of the previous financial year.
This strategy can be particularly relevant for:
Professionals who have recently moved into higher-paying roles.
Business owners whose income fluctuates between financial years.
Individuals who previously prioritised mortgage repayments or other financial commitments.
People returning to higher earnings after a career break.
For example, someone who has recently received a substantial bonus may be able to make additional deductible superannuation contributions using previously unused cap amounts, subject to eligibility.
However, these amounts expire after five years, making it important to understand which unused contributions may be available and when they must be used.
What to consider: Check your available carry-forward amounts through the ATO's online services and obtain advice before making additional contributions.
3. Understand How Division 293 Tax Affects High-Income Earners
One of the more important superannuation tax considerations for higher-income Australians is Division 293 tax.
This is an additional 15% tax that may apply when your income and relevant concessional superannuation contributions exceed $250,000. It effectively reduces the tax concession available to higher-income individuals.
For example, if your income for Division 293 purposes is $240,000 and you make $20,000 in concessional super contributions, your combined amount is $260,000.
In this scenario, the additional 15% tax would generally apply to the $10,000 exceeding the threshold, resulting in a Division 293 liability of $1,500.
Even when Division 293 applies, concessional super contributions may remain tax-effective compared with receiving the same amount as personal taxable income.
However, the overall benefit depends on your circumstances, including your income, contribution arrangements and other financial priorities.
What to consider: If your income is approaching or exceeds $250,000, factor Division 293 into your contribution strategy rather than assuming all concessional contributions will only be taxed at 15%.
4. Consider the Impact of Division 296 Tax on Large Super Balances
For high-income earners who have already accumulated substantial superannuation savings, the introduction of Division 296 tax on 1 July 2026 adds another consideration to long-term wealth planning.
The new legislation introduces additional tax on earnings attributable to the portion of an individual's total superannuation balance exceeding certain thresholds:
Balances above $3 million: An additional 15% tax applies to attributable earnings on the portion above this threshold, bringing the headline tax rate to 30%.
Balances above $10 million: A further 10% applies to attributable earnings on the portion above $10 million, bringing the headline tax rate to 40%.
These thresholds are indexed from 2027–28, and the tax applies to relevant realised earnings rather than unrealised capital gains.
Importantly, Division 296 is based on your total superannuation balance, not your annual salary. Consequently, it may affect individuals who have accumulated substantial retirement savings over many years, regardless of their current income.
For those approaching or exceeding the thresholds, the changes make it particularly important to consider how superannuation fits alongside investments held outside the superannuation system.
For a more detailed explanation, read our article: Division 296 Tax: What the $3 Million Super Balance Changes Mean.
What to consider: If your super balance is approaching $3 million, review the potential implications of Division 296 with your financial adviser before making changes to your contributions, investments or retirement strategy.
5. Consider Non-Concessional Contributions to Grow Your Super
While concessional contributions offer potential income tax benefits, non-concessional contributions provide another opportunity to increase your retirement savings.
These contributions are generally made from money on which you've already paid tax, such as personal savings, investment proceeds or an inheritance.
For the 2026–27 financial year, the standard non-concessional contributions cap is $130,000.
Eligible individuals may also be able to use the bring-forward rules to contribute up to $390,000 over a three-year period, depending on their age, total superannuation balance and previous contribution arrangements.
This may be particularly relevant if you:
Receive a substantial inheritance or windfall.
Sell an investment or business asset.
Have accumulated significant savings outside super.
Want to increase your retirement savings before reducing your working hours.
However, superannuation preservation rules generally restrict access to contributions until you meet a condition of release.
For this reason, contributing additional funds to super must be balanced against your need for accessible savings and investments.
What to consider: Before making a substantial non-concessional contribution, assess your eligibility, available contribution caps and future cash flow requirements.
6. Review Your Superannuation Investment Strategy
As your income and superannuation balance grow, the way your retirement savings are invested becomes increasingly important.
Your existing investment option may no longer reflect your financial circumstances, retirement timeframe or tolerance for risk.
A superannuation investment review should consider:
Asset allocation: How your savings are distributed across shares, property, fixed interest, cash and other investments.
Diversification: Whether your portfolio is overly concentrated in particular sectors or asset classes.
Investment risk: How much market volatility you are comfortable with and financially able to withstand.
Fees and costs: Whether investment and administration fees remain appropriate for the services provided.
Retirement timeframe: Whether your investment strategy aligns with when you expect to access your superannuation.
For high-income earners, it's also important to consider how superannuation investments interact with assets held outside super, including property, shares and business interests.
Rather than treating superannuation as a standalone investment, a coordinated approach can help ensure your overall portfolio reflects your wealth management objectives.
7. Explore Superannuation Strategies With Your Spouse
For couples with significantly different incomes or superannuation balances, reviewing retirement savings together may provide additional planning opportunities.
One option is contribution splitting, which allows eligible individuals to transfer certain concessional contributions to their spouse's superannuation account.
Subject to fund rules and eligibility requirements, up to 85% of eligible concessional contributions from the previous financial year may be transferred.
This can help couples manage differences in superannuation balances and plan more effectively for retirement.
Other possibilities may include spouse contributions, additional personal contributions or coordinating investment strategies across both accounts.
However, each person's contribution caps and superannuation balance must be considered separately.
What to consider: A coordinated strategy should account for both partners' retirement goals, ages, incomes and existing super balances, rather than focusing solely on the higher-income partner.
8. Integrate Superannuation With Your Broader Wealth and Retirement Plan
For high-income earners, superannuation is often only one component of a more complex financial position.
You may also hold investment properties, managed investments, shares, business assets or other sources of wealth.
While superannuation offers valuable tax advantages, it also has contribution restrictions and rules governing when funds can be accessed.
An effective financial strategy therefore needs to consider how much wealth to accumulate inside superannuation and how much to retain in more accessible investments. This becomes particularly important as you approach retirement.
Questions worth considering include:
Will your superannuation balance be sufficient to support your preferred retirement lifestyle?
How much investment income might you need before you can access super?
When should you consider transitioning from accumulation to retirement phase?
How will your superannuation interact with your estate planning arrangements?
Are your investments structured appropriately for your retirement objectives?
Bringing these decisions together through a broader retirement planning strategy can help you manage your financial future with greater clarity.

Eligible individuals may be able to contribute more through the carry-forward or bring-forward rules, depending on their circumstances.
Is salary sacrificing into super worthwhile for high-income earners?
Salary sacrificing may provide tax advantages by directing part of your before-tax income into superannuation. However, the benefit depends on your marginal tax rate, existing employer contributions, concessional contribution cap and any applicable Division 293 tax.
What is Division 293 tax?
Division 293 is an additional 15% tax that may apply to certain concessional superannuation contributions when your income and relevant contributions exceed $250,000. It reduces the tax concession available to higher-income earners.
Should high-income earners maximise their superannuation contributions?
Maximising contributions can be beneficial, but isn't appropriate for everyone. The decision should account for contribution caps, tax implications, investment objectives, liquidity requirements and when you may need access to your money.
Can high-income earners contribute to their spouse's superannuation?
Yes, there are several ways to contribute to or help increase a spouse's superannuation, including personal spouse contributions and eligible contribution splitting arrangements. The rules and tax benefits depend on individual circumstances.
