How it works in practice

Understanding Super Contributions

Superannuation in Australia is a compulsory system designed to provide retirement savings. While employers make mandatory contributions (Super Guarantee), individuals can also make extra contributions to boost their retirement nest egg. These additional contributions offer significant tax benefits and can be made in two main ways: before-tax (concessional) and after-tax (non-concessional).

Types of Extra Contributions

Concessional contributions are made from your pre-tax income, such as salary sacrifice arrangements or personal contributions for which you claim a tax deduction. These are taxed at a lower rate (15% for most people) within your super fund. Non-concessional contributions are made from your after-tax income and are generally not taxed again when they enter your super fund. Both types are subject to annual caps, and exceeding these caps can result in additional tax. Making extra contributions can significantly enhance your financial position in retirement.

Important exceptions

Contribution caps apply to both concessional (before-tax) and non-concessional (after-tax) contributions. Exceeding these caps can lead to extra tax.

There are also age limits for making certain contributions, and a total super balance limit (currently $1.9 million for 2023-24) above which non-concessional contributions cannot be made.

High-income earners may also be subject to Division 293 tax, which imposes an additional 15% tax on concessional contributions if their income plus concessional contributions exceed a certain threshold (currently $250,000).

What you should do now

  1. Understand the difference between concessional (before-tax) and non-concessional (after-tax) contributions and their respective tax treatments.

  2. Research the current annual contribution caps for both types of contributions to ensure you do not exceed them.

  3. Determine the best contribution strategy for your personal circumstances, considering your income, age, and retirement goals.

  4. Arrange your contributions either through a salary sacrifice agreement with your employer or by making personal contributions directly to your super fund.

  5. Regularly review your contribution strategy with a financial advisor to adapt to changes in your financial situation and superannuation laws.
