The benefits of salary sacrificing into super

salary sacrifice 

16 March 2022

Depending on your income, salary sacrifice can be a tax-effective way to grow your super, on top of your employer’s regular Superannuation Guarantee contributions.

How does salary sacrifice work?

Salary sacrifice is an arrangement between you and your employer to make an additional contribution to your super from your before-tax pay.

Salary sacrifice is generally only tax-effective for people with middle to high incomes, earning more than $45,000 per year (as at 2021/22).

The potential benefits of salary sacrifice

  • Pay less tax
    A salary sacrifice contribution is taxed at 15% when it enters your super. This rate tends to be lower than the marginal tax rate if you earn more than $45,000 per year.
  • Reduce your taxable income
    As well as paying less tax on your salary sacrifice contributions, you will be reducing your taxable income – and this could mean you will pay less tax on the rest of your salary.
  • Grow your super
    Your super is a long-term investment which takes advantage of compound interest. Making additional contributions through salary sacrifice can give your super a boost and make a big difference to your future retirement.

Here is an example to show you how someone’s overall financial position can benefit from a salary sacrifice arrangement.

Example: John

John works full time, earning $80,000 per year. He decides to make an arrangement with his employer to salary sacrifice $50 per week into his super.

John’s salary sacrifice will reduce his taxable income. So over 12 months, his income tax will reduce from $16,987 to $16,090.

The salary sacrifice will reduce John’s take-home pay by $1,703, but he will have contributed an extra $2,210 (after 15% tax).

This means that over 12 months, John will save $507 in tax as well as giving his super balance a boost.

Before-tax versus after-tax contributions

Local government employers may offer higher contribution arrangements, which can include personal (after tax) contributions.

Depending on their situation, an individual may be able to pay more into their super while keeping the same take-home pay if they switch from personal contributions to salary sacrifice (before-tax) contributions.

Here is an example to show you how this can work.

Example: Sara

Sara works full time and earns $80,000 per year. She has a higher contribution arrangement with her employer, enabling her to make a 5% personal (after-tax) contribution to her super.

  • Annual personal contributions: $4,000
  • Take home pay: $59,013

Sara decides to change her 5% personal contribution to a salary sacrifice (before-tax) contribution, which increases her take home pay by $1,395.

She then contributes this $1,395 back into her super through a further salary sacrifice contribution.

Sara’s new situation is:

  • Annual salary sacrifice contributions, after 15% tax deduction: $5,191
  • Take home pay: $59,013

You should consider receiving financial adviser before making any decisions.

Things to consider

Salary sacrifice can be tax-effective for many people, but it isn’t suitable for everyone. Here is a list of things to look out for:

  • Although salary sacrifice can reduce your taxable income, it may not change your assessable income, which is used to calculate various tax rebates and Family Tax Benefit.
  • Check with your employer to determine if any employment benefits you currently receive that are based on your salary could be reduced under a salary sacrifice arrangement, including your employer’s Superannuation Guarantee contributions.
  • Watch out for your concessional (before tax) contributions cap, which is $27,500 for the financial year (2021/22). If you exceed your cap, you may have to pay extra tax.

We recommend that you check that you are staying under your cap during the financial year. The quickest and easiest way to check how close you are to your cap is to log in to your account.
