  • Australians can boost their super before retirement with top-up and catch-up strategies.
  • Salary sacrifice and carry-forward rules help maximise contributions and tax efficiency.
  • Even small additional contributions can significantly grow your retirement balance over time.

Superannuation is the cornerstone of retirement savings for many Australians. Yet, as retirement approaches, many discover their balance may not fully support the lifestyle they envision. Fortunately, there are effective ways to boost your super before you retire, even if you’re starting late. Understanding top-up and catch-up strategies can make a meaningful difference to your long-term financial comfort.

Understanding Super Contributions

Superannuation is built primarily through employer contributions, known as Superannuation Guarantee (SG) payments, currently set at 11.5% of your ordinary time earnings (11.5% for FY24/25, 12% for FY25/26).  While these regular contributions accumulate over time, voluntary contributions can significantly accelerate your balance growth, especially during your peak earning years.

Broadly, there are two categories of voluntary contributions: concessional and non-concessional.

  • Concessional contributions are made before tax, such as employer SG payments or salary sacrifice contributions, and are taxed at 15% within your super fund.
  • Non-concessional contributions are made after-tax, typically from your take-home income or savings, and aren’t taxed again inside the fund.

Every financial year, the Australian Taxation Office (ATO) reviews and updates key superannuation caps, rates, and thresholds. From 1 July 2025, the following caps have been applied.

Salary Sacrifice: A Simple Top-Up Tool

One of the easiest ways to boost your super is through salary sacrificing. This involves directing a portion of your pre-tax salary into your super account instead of receiving it as take-home pay.

The key benefit? Tax efficiency. For most people, the 15% super contributions tax is lower than their marginal income tax rate. Over time, this strategy not only reduces taxable income but also enhances compounding growth within the fund.

As of 2025, the annual concessional contributions cap is AUD 30,000, which includes both employer SG and salary sacrifice amounts. Exceeding the cap can attract additional tax, so it’s important to monitor contributions closely.

Catch-Up Contributions: Making Up for Lost Time

If you’ve had career breaks, part-time work, or simply missed contributing in the past years, the carry-forward (catch-up) rule offers a valuable opportunity.

Under this rule, if your total super balance is below AUD 500,000, you can carry forward any unused concessional contributions for up to five years. This means that in a year when you have additional income, for example, from a bonus or asset sale, you can make larger tax-deductible contributions and boost your super faster.

This feature is particularly useful for Australians in their 50s who are entering their higher-earning years and looking to maximise super growth before retirement.

After-Tax Contributions and the Bring-Forward Rule

In addition to concessional contributions, you can make non-concessional (after-tax) contributions up to AUD 120,000 per year.

If you have surplus savings, the bring-forward rule allows you to contribute up to AUD 360,000 at once (using three years’ worth of caps), subject to eligibility criteria. This can be an effective strategy for those selling an investment property, downsizing, or receiving an inheritance.

The Power of Small Steps

Even modest increases in contributions can add tens of thousands of dollars to your retirement balance over time, thanks to compounding returns. Regular reviews of your super fund can help tailor a contribution strategy aligned with your goals, income, and tax situation.

Remember, it’s never too late to strengthen your super. By understanding and using top-up and catch-up strategies, you can turn the years before retirement into your most financially rewarding.
