The Benefits of Making Additional Contributions

There are both long-term and short-term benefits to making additional contributions to your super. Below are five key benefits you may like to consider:


1. Compound interest

According to the government’s MoneySmart website, compound interest is the interest you earn on the money you initially deposited into an account AND the interest you’ve already earned (i.e. the interest on your interest). The power of compounding helps you save more money because the longer you save, the more interest you earn, assuming interest rates are positive.

As an example (using the MoneySmart Compound Interest Calculator), someone with $15,000 in their account who deposits just $10 a week for the next 30 years could end up with over $100,000!*

*The graph above is from the MoneySmart website and assumes an annual interest rate of 5.00%, compounded monthly. For detailed assumptions, visit the and enter the details shown above.


2. Ability to claim tax deductions on after-tax contributions

After-tax super contributions are non-concessional contributions unless you then claim these as a tax deduction (at which point they become concessional contributions). Claiming a tax deduction on any after-tax contributions that you make, may reduce your taxable income for that financial year.

Claiming a deduction on after-tax contributions an option for people who are self-employed or others who cannot salary sacrifice via their employer. Click here to read the steps you’ll need to take if you wish to do this.


 3. Government super co-contribution

The government super co-contribution is designed to help boost the retirement savings of eligible individuals. If your income is under a certain threshold and you make an after-tax contribution to your Christian Super account, the government will also make a contribution of up to $500 each financial year.

4. Potential tax offsets

There are a couple of tax offsets that you may be able to access if you meet the eligibility criteria.

Low Income Super Tax Offset 

If you earn $37,000 or less a year, and you (or your employer) make concessional super contributions, the government may refund the tax you paid on those contributions back into your super account, up to a maximum of $500 per year. This is called the Low Income Super Tax Offset (LISTO).

If you’re eligible for the LISTO, it will be automatically calculated by the ATO and deposited in your super account after you lodge your tax return. You need to make sure that your super fund has your Tax File Number (TFN), otherwise they will be unable to accept a LISTO payment.

For further information about the LISTO, please visit the ATO website.

Spouse contribution tax offset 

If your spouse isn’t working or if their income is under a certain amount, you may be eligible for a tax offset of up to $540 per year if you make an after-tax contribution into their super account and meet certain conditions. Click here to learn more.


5. Downsizer contributions

If you are 65 year old or older and meet the eligibility requirements, you may be able to make a downsizer contribution into your superannuation of up to $300,000, using the proceeds from the sale of your home.

Your downsizer contribution is NOT considered as a non-concessional contribution so it will not count towards your contribution caps. The ATO website has further information about this contribution type.

It’s important to note that making additional contributions doesn’t benefit everyone, and not everyone is eligible to take advantage of some of the benefits of making additional contributions.
