Extra contributions

Even small additional contributions to your account each month can make a big difference to the size of your super account.


There are two ways you can make extra contributions to your super: before tax and after tax.


Before tax (concessional contributions)

Salary sacrifice 

You can make extra contributions by ‘sacrificing’ some of your salary. The extra contributions go directly from your salary into your super, the same way your normal super guarantee contributions are paid by your employer.

Your take home pay will be less, however salary sacrificing will reduce your annual assessable income, so the potential tax benefits are worth considering. Your concessional super contributions are taxed at 15%. If your income tax rate is higher than 15%, then you will save money on tax.

You should seek financial advice about whether salary sacrifice is right for you. Also check that your employer will continue to calculate their SG contribution and your other entitlements on your pre-sacrifice salary.


After-tax (non-concessional contributions)

Personal contributions

You can make extra contributions in lump sums from your normal take home pay. This is not taxed as you’ve already paid the tax on your income.

Keep in mind there are annual limits on the amount of after-tax contributions you can make into your super account each financial year.  The non-concessional contribution cap is $110,000 for the 2022-23 financial year.  

See How Super is Taxed.

Important information

Your super contributions are counted from the date the payment is allocated to your super account and not when the payment is sent.  If you are making a contribution before the end of the financial year, you need to allow enough time for your contribution to be received and allocated to your super account. 


Government top-up for low income earners

If you earn less than $57,016  p.a. and make a personal contribution into your super, you may be eligible for the Government co-contribution and receive up to $500 extra into your super each year. For eligibility criteria, see the ATO website.


Tax offset for spouse contributions 

There may be times during your working life where your partner may work part-time, take time off to raise children, study, look after others or recover from an illness. This can impact their super savings, leaving them less in retirement.

If your partner is on a low income or no income and you make a contribution to their super, not only will you help grow their super but you can claim a tax offset of up to $540. See if you are eligible: 

  • Both you and your spouse are Australian residents when you made the contribution.
  • A spouse can be of any sex and include de facto relationships.
  • You and your spouse are not living separately or apart on a permanent basis when you made the contributions.
  • Contributions were not tax deductible.
  • The contributions need to be made to a complying fund (like REI Super) during the same financial year as claiming the offset.
  • Your spouse’s assessable income, total reportable fringe benefits and employer superannuation contributions are less than $40,000.
  • Your spouse does not have a super balance of $1.7 million or more.

If you make a spouse contribution, it counts towards their non-concessional contributions cap and not your own.
