How does salary sacrifice save tax?
Instead of receiving $10,000 as salary (taxed at your marginal rate), it goes directly into your super fund, where it's only taxed at 15%. The difference between your marginal rate and 15% is your tax saving.

Understanding Salary Sacrifice on $255K
On a $255,000 salary, you sit in the 45% tax bracket ($190,001+) for the 2025–26 financial year. Your marginal tax rate is 45%, plus the 2% Medicare levy, for a combined marginal rate of 47%.
When you salary sacrifice into super, the redirected amount is taxed at just 15% inside the super fund instead of your marginal rate. That means every dollar you sacrifice saves you 32 cents in tax — the difference between 47% and 15%.
HECS-HELP note
Salary sacrifice does not reduce your HECS repayment. Your HECS repayment income includes reportable employer super contributions (which includes salary sacrifice), so the repayment amount remains approximately the same regardless of how much you sacrifice.
Your employer already contributes $30,600 in Superannuation Guarantee (12% of $255,000). With a $10,000 salary sacrifice on top, your total concessional contributions reach $40,600, leaving $0 of the $30,000 cap unused. Contributions above the cap are added back to your assessable income and taxed at your marginal rate.
