Navigating the types and limits of superannuation contributions can feel like decoding a complex puzzle. But understanding the difference between concessional and non-concessional contributions is crucial to maximising your retirement savings while avoiding unnecessary tax penalties.
What are concessional contributions?
Concessional contributions are generally made from your before-tax income and include: employer super guarantee contributions; and salary sacrifice contributions. Concessional contributions also include: after-tax personal contributions you claim as a tax deduction; paid parental leave super contributions; and after-tax contributions from certain third parties to your super fund – including parents and friends, or your spouse who lives separately and apart on a permanent basis. Note that spouse contributions and contributions from parents to children under the age of 18 are not concessional contributions. Concessional contributions are taxed at 15% within the fund (with the tax paid from your contributions), making this an effective way to reduce your overall tax burden while building retirement savings. The annual limit on concessional contributions for 2025–2026 is generally $30,000, depending on your total superannuation balance and other factors.
What are non-concessional contributions?
Non-concessional contributions come from amounts that have already been taxed and don’t attract additional tax unless you exceed the cap. These include: spouse contributions (where your spouse isn’t your employer); contributions for a child under 18 (if the contributor is not the child’s employer); personal contributions from your after-tax salary that you don’t claim as a personal tax deduction; excess concessional contributions not released from your fund; and most transfers from foreign super funds. The annual limit on non-concessional contributions for 2025–2026 is generally $120,000, depending on your total super balance and other factors.
Special exclusions to take into account
Certain contributions don’t count towards your non-concessional cap: contributions of certain CGT exempt sale proceeds from your small business; personal injury payments; downsizer contributions from home sales; government co-contributions; and re-contributions of COVID-19 early release amounts. Apart from government co-contributions, you must specifically request these exclusions using the appropriate forms before or when making contributions.
The importance of contribution caps
Your superannuation enjoys preferential tax treatment, but this comes with limits. If you exceed the annual limits that apply to you, higher tax rates apply to those contributions above your limit. All contributions across multiple funds count towards your caps, so careful tracking is essential. High-income earners earning over $250,000 (including concessional super contributions) may also face an extra 15% tax on some of their concessional contributions.
Key takeaways
Understanding contribution types helps you: maximise tax benefits through strategic contribution timing; avoid excess contribution penalties; plan effectively for retirement; and take advantage of available exemptions and exclusions. Remember that your age, work status and total super balance can also affect contribution eligibility and fund acceptance rules. Strategic planning becomes increasingly important as your circumstances change throughout your working life and as you approach retirement.

Frequently asked questions
What is the difference between concessional and non-concessional contributions?
Concessional contributions are made from before-tax income and are taxed at 15% within the fund. They include employer super guarantee contributions, salary sacrifice contributions, and after-tax personal contributions you claim as a tax deduction. Non-concessional contributions come from money that has already been taxed and do not attract additional tax unless you exceed your cap. They include personal after-tax contributions you do not claim as a deduction, and most spouse and child contributions.
What are the contribution caps for 2025-2026?
The concessional contributions cap for 2025-2026 is generally $30,000. The non-concessional contributions cap is generally $120,000. Both limits can vary depending on your total superannuation balance and other individual factors, so it is worth confirming your specific cap before making large contributions.
Are spouse contributions concessional or non-concessional?
It depends on the relationship. Contributions made by a spouse who does not live with you on a permanent basis may be treated as concessional. However, standard spouse contributions where you contribute to your partner’s super fund are generally non-concessional and count towards the receiving spouse’s non-concessional cap.
Which contributions are excluded from the non-concessional cap?
Several types of contributions are excluded and do not count towards the non-concessional cap. These include certain CGT-exempt sale proceeds from a small business, personal injury payments, downsizer contributions from the sale of a home, government co-contributions, and re-contributions of amounts withdrawn under the COVID-19 early release scheme. With the exception of government co-contributions, you generally need to complete the appropriate forms to request these exclusions before or at the time of making the contribution.
What happens if I exceed my contribution caps?
Contributions above your cap are taxed at higher rates, which can significantly reduce the benefit of making those contributions in the first place. It is important to track all contributions across every fund you hold, as the caps apply to the total across all funds combined.
Do high-income earners pay more tax on super contributions?
Yes. If your income including concessional super contributions exceeds $250,000, an additional 15% tax applies to some of your concessional contributions under the Division 293 tax rules. This means the effective tax rate on those contributions rises from 15% to 30%, which is still generally lower than the top marginal rate but worth factoring into your planning.
Can my age or work status affect my ability to contribute to super?
Yes. Age, work status and your total super balance can all affect your eligibility to make contributions and whether your fund is required to accept them. The rules become more complex as you approach and move through retirement, which is why personalised advice becomes increasingly important at that stage.
