Making regular pre-tax contributions is one way that you can build your superannuation balance and potentially save on taxes.

How does salary sacrificing into super work?

Depending on the amount you earn, you may end up paying less tax by requesting your employer to pay a portion of your before-tax salary into your super account, instead of receiving it as take home pay. This is because these pre-tax contributions are taxed at 15% (if you earn below $250,000 a year¹) or 30% (if you earn $250,000 or more a year), which is often lower than what most people pay on their salaries.

Also known as salary sacrificing or concessional contributions, these pre-tax contributions can also be an effective way to help you increase your super balance.

If you are between 67 and 74 years old, you must fulfil a work test that shows you were employed for at least 40 hours over a consecutive 30-day period before you can make voluntary super contributions. 

What do I need to do to participate in salary sacrificing?

There are a few things you may like to check as part of your decision to salary sacrifice into super:

  • Whether your employer offers salary sacrifice arrangements. If they do, ask them for the forms you need to complete. Alternatively, you can complete our Voluntary Pre-tax Contributions form and submit it to your payroll team.
  • Familiarise yourself with the Contributions factsheet.
  • Calculate how much you can afford to salary sacrifice given that your disposable income will be reduced.
  • Check that you are still within the concessional contributions cap across all your super funds as you could pay extra tax if you exceed the limit. To check the amount of concessional contributions for your Australian Catholic Superannuation account, log in online. You can find this information in the ‘Super balance history’ section under the ‘Dashboard’ tab. If you exceed the $27,500 cap per year, you may have to pay extra tax.
  • If your total super balance is less than $500,000 as at 30 June the previous financial year, you may qualify to carry forward any unused concessional contributions from 1 July 2018, up to a maximum of five years.
¹This refers to the adjusted taxable income, which amongst other things, includes your reportable employer super contributions and any deductible personal super contributions.

Example on how you could potentially be better off with salary sacrificing

The example below shows how Sally can be better off when she salary sacrifices into super.

Sally earns a gross income of $100,000 per year. She decides to salary sacrifice 5% of her gross salary into super. Using the Superannuation Contributions Calculator², she calculates the result of making concessional contributions and compares this to the scenario if she had not made the contributions:


Annual salary and tax details    
  With 5% salary sacrifice¹ Without salary sacrifice 
Gross income per year  $100,000  $100,000 
Salary sacrifice contribution  -$5,000  -$0 
Taxable income  $95,000  $100,000 
PAYG tax^  -$22,314  $24,189 
Annual take home pay $72,686  $75,811 


Super contributions    
  With 5% salary sacrifice¹  Without salary sacrifice 
Employer Superannuation Guarantee (SG) contributions $10,000 $10,000
Salary sacrifice contribution $5,000 $0
Contributions tax (15%) -$2,250 -$1,500
Net super contributions $12,750 $8,500

^ Although Sally’s take home pay reduces by $2,943 per year under the salary sacrifice arrangement, she added a net amount of $4,250 to her retirement savings. Sally also saved $1,875 in PAYG taxes that her employer would have otherwise withheld from her gross salary. Overall, Sally is better off by $1,125 as this represents the total tax savings for her (i.e. $1,875 saved personally minus $750 paid within superannuation).

Low income super tax offset (LISTO)

If you earn $37,500 or less a year and you or your employer makes concessional contributions, you may be eligible for a refund of the 15% contribution tax you have paid via a government superannuation payment of up to $500 paid to your super.

If you are eligible and have informed us of your tax file number (TFN), the Australian Tax Office will make the payment directly to your account.

To check if we have your TFN, log in to your account and navigate to ‘My details’ followed by ‘View/update personal details’. If you have not informed us of your TFN, please contact us.
