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 $55K
On a $55,000 salary, you sit in the 30% tax bracket ($45,001–$135,000) for the 2025–26 financial year. Your marginal tax rate is 30%, plus the 2% Medicare levy, for a combined marginal rate of 32%.
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 17 cents in tax — the difference between 32% and 15%.
Your employer already contributes $6,600 in Superannuation Guarantee (12% of $55,000). With a $10,000 salary sacrifice on top, your total concessional contributions reach $16,600, leaving $13,400 of the $30,000 cap unused. Contributions above the cap are added back to your assessable income and taxed at your marginal rate.
