What is superannuation?
Superannuation, commonly called "super," is Australia's compulsory retirement savings system. Your employer is legally required to contribute a percentage of your ordinary time earnings into a registered super fund on your behalf. These contributions, along with investment returns earned over decades, form a significant part of most Australians' retirement income.
Super is designed to supplement the Age Pension and provide a comfortable standard of living in retirement. For high-income professionals, super is also one of the most tax-effective wealth building vehicles available in Australia, making it a critical component of any long-term financial strategy.
The super guarantee rate
As of FY2024-25, the Super Guarantee (SG) rate is 11.5% of your ordinary time earnings. This rate has been gradually increasing and is legislated to reach 12% by 1 July 2025. Your employer must pay this on top of your salary — it is not deducted from your pay.
For someone earning $200,000 per year, the SG contribution alone amounts to $23,000 annually. Over a 25-year career with investment growth, these compulsory contributions can accumulate to well over $1 million. You can model the impact of SG contributions on your retirement balance using the superannuation modelling features in Wealth Dashboard.
Concessional contributions
Concessional (before-tax) contributions include your employer's SG payments, salary sacrifice arrangements, and personal deductible contributions. These are taxed at just 15% inside your super fund, compared to your marginal tax rate which could be as high as 47% (including the Medicare levy) for income above $190,000.
The concessional contributions cap for FY2024-25 is $30,000 per financial year. If you haven't used your full cap in previous years, you may be able to carry forward unused amounts for up to five years, provided your total super balance was below $500,000 at the previous 30 June. This carry-forward provision creates opportunities for high-income earners to make significant catch-up contributions in years when cash flow allows.
To understand how concessional contributions interact with your overall tax position, explore the tax calculations in Wealth Dashboard.
Non-concessional contributions
Non-concessional (after-tax) contributions are made from your after-tax income. While there is no additional tax on these contributions entering the fund, the investment earnings within super are taxed at a maximum of 15%, which is typically lower than the tax you would pay on investment earnings held in your personal name.
The non-concessional contributions cap is $120,000 per financial year for FY2024-25. If you are under 75 and your total super balance is below $1.9 million, you may be eligible to bring forward up to three years of non-concessional contributions, allowing a lump sum contribution of up to $360,000 in a single year. This can be particularly useful when receiving a windfall such as an inheritance or property sale proceeds.
Division 293 tax
If your income plus concessional super contributions exceed $250,000, you may be subject to Division 293 tax. This imposes an additional 15% tax on the concessional contributions that push you over the threshold, bringing the effective tax rate on those contributions to 30%. While this reduces the tax advantage, a 30% rate is still lower than the top marginal rate of 47%, meaning super contributions remain tax-effective for most high-income earners.
Choice of fund
Most employees have the right to choose which super fund receives their employer contributions. When selecting a fund, key factors to consider include investment performance over the long term (at least 7-10 years), fees (both administration and investment), insurance options, and the range of investment choices available.
Industry funds and retail funds each have different fee structures and investment approaches. Self-managed super funds (SMSFs) offer maximum control but come with significant regulatory obligations and are generally only cost-effective for balances above $200,000-$500,000.
Investment options within super
Most super funds offer a range of investment options spanning conservative (heavy cash and bonds allocation) through to high growth (predominantly shares and property). Your investment option choice should reflect your time horizon, risk tolerance, and overall financial position.
For someone in their 30s with 25-35 years until preservation age, a growth or high-growth option may be appropriate, as there is time to ride out market volatility. As you approach retirement, gradually shifting to a more balanced allocation can help protect your balance from a significant market downturn right before you need to draw on it.
You can model different growth rate assumptions on your super balance using the FIRE calculator to see how investment returns compound over time.
Preservation age and accessing your super
Your preservation age depends on your date of birth. For anyone born after 30 June 1964, the preservation age is 60. You generally cannot access your super before reaching preservation age, with limited exceptions such as severe financial hardship, permanent incapacity, or a terminal medical condition.
Once you reach preservation age and meet a condition of release (such as retiring from the workforce), you can access your super as a lump sum, an income stream (account-based pension), or a combination of both. Income drawn from a super pension after age 60 is tax-free, which makes super one of the most tax-effective sources of retirement income.
Transition to retirement
A transition to retirement (TTR) strategy allows you to access your super as a pension once you reach preservation age, even if you are still working. This can be used to supplement your income if you reduce your working hours, or in combination with salary sacrifice to boost your super balance while maintaining your take-home pay.
TTR pensions have some restrictions — you can withdraw between 4% and 10% of your account balance each financial year, and you cannot take lump sum withdrawals until you meet a full condition of release. The investment earnings in a TTR pension are taxed at 15%, the same rate as in the accumulation phase.

Insurance in super
Most super funds provide default insurance cover, typically including life insurance (death cover), total and permanent disability (TPD), and income protection. Holding insurance through super can be more affordable than retail policies because funds can negotiate group rates, and premiums are deducted from your super balance rather than your take-home pay.
However, default cover may not be adequate for your circumstances. High-income earners often need higher levels of cover to protect their family's lifestyle and financial obligations. Review your insurance needs regularly, particularly after major life events like purchasing a property, having children, or changing jobs.
It is also important to be aware that holding multiple super accounts means paying multiple sets of insurance premiums and fees, which can erode your balance over time. Consolidating to a single fund is often worthwhile, but check that you will not lose valuable insurance cover in the process.
Super as part of your FIRE strategy
For those pursuing financial independence, super plays a unique role. Because it generally cannot be accessed before preservation age, you need sufficient assets outside super to fund your lifestyle from your target retirement age until you can draw on your super. This creates a two-bucket approach: investments outside super to bridge the gap, and super to fund later retirement years tax-effectively.
Wealth Dashboard's superannuation modelling and tax calculations can help you understand how super fits into your overall wealth projection and FIRE timeline. By modelling different contribution strategies and growth assumptions, you can find the balance between maximising tax-effective super contributions and building accessible wealth outside super.
