Could you have unused super contribution cap space available from previous years? Understanding your carry-forward concessional contributions may help you make more informed decisions about building your super and managing your taxable income.

The carry-forward rules allow eligible Australians to use unused portions of their concessional contributions cap from the previous five financial years. This can be particularly useful if your income varies from year to year, you have taken time out of the workforce, or you are looking to increase your super contributions later in your working life.

What are concessional contributions?

Concessional contributions are generally contributions made to super before tax. They commonly include:

• Superannuation Guarantee contributions made by your employer.
• Salary sacrifice contributions.
• Personal super contributions for which you claim a tax deduction.

Concessional contributions that fall within the applicable cap are generally taxed at up to 15% within the super fund, although different tax treatment can apply in some circumstances, including for higher-income earners.

What are carry-forward or ‘catch-up’ contributions?

If you do not use all of your concessional contributions cap in a financial year, the unused amount may be carried forward for up to five financial years. If you meet the eligibility requirements, you may then be able to use some or all of those unused amounts in a later year.

This does not create a separate type of contribution. Instead, it can increase the amount of concessional contributions you are able to make in a particular year without exceeding your available cap.

Who may be eligible?

Eligibility depends on the superannuation rules applying at the time you make the contribution. Under the rules outlined in the source material, using carried-forward unused concessional cap amounts requires your total super balance at the previous 30 June to be below $500,000, as well as having unused concessional cap space available from the previous five financial years.

Contribution eligibility, age-based rules and the requirements for claiming a personal tax deduction also need to be considered. Unused cap amounts only remain available for five financial years, so older amounts can expire if they are not used.

How can you check your available carry-forward amount?

One of the easiest ways to review the information held by the Australian Taxation Office (ATO) is through myGov.

1. Log in to myGov
Go to your myGov account and sign in.

2. Open the ATO service
Select the Australian Taxation Office from your linked services.

3. Select ‘Super’
From the ATO online services menu, open the Super section.

4. Open the carry-forward information
Choose ‘Information’ and then ‘Carry forward concessional contributions’.

5. Select the relevant financial year
Use the financial-year selector to view your total super balance, eligibility status and unused concessional contributions available to carry forward.

6. Review the detail
Select ‘Show details’ to see how the available amount has been calculated, including concessional contributions reported for individual financial years.

Don’t rely on myGov alone

The information displayed in myGov is based on data reported to the ATO. There can be a delay between a contribution being received by your super fund and that information appearing in the ATO system. Reporting errors can also affect what is displayed.

For this reason, it is important to compare the ATO information with your own records and the contribution history supplied by your super fund, particularly before making a large additional contribution.

Why this can matter for your retirement strategy

Carry-forward contributions can create valuable planning opportunities. Depending on your circumstances, they may allow you to contribute more to super in a year when your cash flow is stronger, after returning to work, following the sale of an investment or business asset, or as retirement gets closer.

However, making additional super contributions should be considered as part of your broader financial strategy. Contribution caps, your total super balance, tax position, access to funds and retirement goals can all influence whether using carried-forward cap space is appropriate.

Before making an additional contribution

Checking how much unused cap space you have is a useful starting point, but it is not the same as deciding how much you should contribute. The superannuation and tax rules can be complex, and exceeding your available cap may result in additional tax consequences.
