Salary Sacrifice at $150k: How Much Tax Could You Save?
The comparison below models your $150k salary with and without a $15k salary sacrifice. You'll see the impact on take-home pay, total super contributions, and effective tax rate. For many employees in the 37% marginal bracket, the reduced cash flow is more than offset by accelerated retirement savings and meaningful tax savings — especially if you're not relying on every pre-tax dollar for day-to-day expenses.
Frequently asked questions
How much tax do I save by salary sacrificing $15k at $150k?
At $150k your marginal rate is 37%. Salary sacrificing $15k shifts that amount from 37% personal tax to 15% super contributions tax, saving you roughly $3,300 per year in tax. The exact figure depends on your other deductions and offsets — use the calculator above for a precise comparison.
What is the concessional super cap for 2025–26?
The concessional (before-tax) super cap is $30,000 for 2025–26. This includes your employer's 11.5% super guarantee contribution, so if your employer contributes $17,250, you have about $12,750 of cap space remaining for salary sacrifice. Exceeding the cap means the excess is added to your assessable income and taxed at your marginal rate.
Does salary sacrifice reduce my HELP repayment income?
No. Reportable employer super contributions (including salary sacrifice) are added back to your income when the ATO calculates your HELP Repayment Income (HRI). So sacrificing into super won't reduce your HELP or HECS repayment. It will, however, still lower your income tax — the two obligations are calculated on different income definitions.
