Superannuation Strategies for High-Income Earners
For high-income earners in Australia, superannuation offers valuable opportunities to build substantial retirement savings in a tax-effective manner. Leveraging strategies such as maximising contributions, using salary sacrifice, and understanding concessional limits can make a significant difference in retirement outcomes. In this guide, we’ll explore key superannuation strategies tailored for high-income earners.
Maximising Super Contributions
One of the most effective ways to grow your superannuation is by maximising contributions. By making regular contributions, high-income earners can take advantage of compound growth, tax benefits, and increased wealth over time. There are two primary types of super contributions: concessional and non-concessional.
Concessional vs. Non-Concessional Contributions
Understanding the difference between concessional and non-concessional contributions is essential for high-income earners aiming to maximise their super.
- Concessional Contributions: These are contributions made from pre-tax income, such as employer contributions and salary sacrifice. Concessional contributions are capped at $30,000 per financial year (as of the current tax year). They are taxed at 15% within the super fund, which is generally lower than the marginal tax rate for high-income earners, making it a tax-effective strategy.
- Non-Concessional Contributions: These are contributions made from after-tax income. While non-concessional contributions do not receive the same tax benefits as concessional contributions, they are still an effective way to grow super. The annual cap for non-concessional contributions is $120,000, with a three-year bring-forward rule allowing up to $360,000 to be contributed in a single year, depending on total super balance.
Maximising both types of contributions can help high-income earners boost their retirement savings while optimising tax benefits. Working with a financial adviser can provide personalised advice on how best to balance concessional and non-concessional contributions.
Benefits of Salary Sacrifice
Salary sacrificing into super is an attractive strategy for high-income earners. By redirecting a portion of pre-tax income into superannuation, individuals can reduce their taxable income, potentially lowering their overall tax bill while growing their retirement savings.
How Salary Sacrifice Works
When you opt for salary sacrifice, your employer diverts a specified portion of your pre-tax salary directly into your super fund. This contribution is classified as a concessional contribution, taxed at the super fund’s concessional rate of 15%. For high-income earners, who may otherwise be taxed at the highest marginal rate, this approach can result in significant tax savings.
Additional Benefits of Salary Sacrifice
- Tax Efficiency: By reducing taxable income, salary sacrifice can lower the amount of tax paid annually, resulting in both immediate and long-term financial benefits.
- Increased Super Balance: Regular salary sacrifice contributions compound over time, building a larger super balance for retirement.
- Reduced Adjusted Taxable Income: Reducing taxable income through salary sacrifice can also help high-income earners avoid certain tax surcharges and levies.
For optimal results, salary sacrifice should be implemented strategically. A financial adviser can help determine the right contribution amount to avoid exceeding the concessional cap and ensure the best tax outcomes.

Minimising Taxes Through Super
Tax management is an integral part of any superannuation strategy, particularly for high-income earners. There are several ways super can be used to minimise tax:
- Concessional Contribution Tax: Contributions to super are taxed at 15%, which is generally much lower than the marginal tax rate for high-income earners. This makes concessional contributions a tax-effective way to save for retirement.
- Transition to Retirement Pension: Once you reach preservation age (for most people this is age 60), you can start a transition-to-retirement pension (TTR). This allows you to access part of your super while continuing to work, potentially creating an opportunity to maintain income while contributing additional funds to super in a tax-efficient way.
- Investment Growth within Super: Earnings on investments within a super fund are taxed at 15% (and 10% for capital gains on assets held longer than 12 months). This tax rate is lower than the marginal rate for high-income earners, making super an attractive vehicle for investment growth.
By working with a financial adviser, high-income earners can ensure they’re taking full advantage of the tax benefits available through superannuation, maximising both contributions and investment growth while minimising taxes.
