How Salary Sacrifice Into Super Works in Australia
Salary sacrifice is an arrangement between you and your employer where you agree to forgo part of your pre-tax salary in exchange for your employer making additional superannuation contributions on your behalf. Because the sacrificed amount is paid before income tax is deducted, it reduces your taxable income for the year. The sacrificed contributions are taxed inside the super fund at a concessional rate of 15%, which is typically much lower than your marginal tax rate.
For example, if your marginal tax rate is 32.5% plus 2% Medicare Levy (34.5% effective), every dollar you salary sacrifice into super saves you 19.5 cents in tax compared to receiving it as ordinary income. This makes salary sacrifice one of the most straightforward and effective tax-planning strategies available to Australian employees, especially those in the middle to higher income brackets.
Concessional Super Cap and Excess Contributions Tax
The concessional contributions cap for 2024-25 is $30,000 per year. This cap includes all concessional contributions: your employer's Superannuation Guarantee (SG) contributions, any salary sacrifice amounts, and any personal deductible contributions you claim. If your total concessional contributions exceed $30,000, the excess is added to your assessable income and taxed at your marginal rate, plus an excess concessional contributions charge based on the SIC rate.
You may also be able to carry forward unused concessional cap amounts from up to five previous financial years if your total super balance was below $500,000 at the end of the previous June 30. This can be particularly useful if you receive a bonus, inheritance, or have a high-income year where you want to maximise super contributions. Additionally, individuals earning more than $250,000 in income plus concessional super contributions may be subject to Division 293 tax, which imposes an additional 15% tax on some or all concessional contributions.
Who Benefits Most From Salary Sacrifice
Salary sacrifice provides the greatest tax benefit to employees in higher marginal tax brackets. An employee earning $120,000 who sacrifices $10,000 per year saves approximately $1,950 in tax annually compared to taking the same amount as salary. For someone earning $200,000, the same $10,000 sacrifice saves about $3,200 after accounting for the 15% contributions tax inside super. The savings increase further for those above $180,000 due to the 47% top marginal rate including Medicare Levy.
Lower-income earners below $45,000 may see smaller benefits because the difference between their marginal rate (19% plus Medicare) and the 15% super contributions tax is minimal. Those earning below $18,200 may actually be worse off salary sacrificing into super, since their marginal tax rate is 0% but super contributions are still taxed at 15%. The government's low income super tax offset (LISTO) refunds the 15% contributions tax for individuals earning up to $37,000, which can offset this disadvantage for very low earners.
Tips for Maximising Your Salary Sacrifice Strategy
Start by checking your existing concessional contributions. Your employer's SG at 11.5% on a $100,000 salary already contributes $11,500 per year toward the $30,000 cap, leaving room for $18,500 in salary sacrifice. Always confirm your employer is willing to enter a salary sacrifice arrangement and understand whether it affects other entitlements like leave loading, overtime calculations, or redundancy pay, as some enterprise agreements calculate these on the pre-sacrifice salary.
Consider spreading your sacrifice evenly across pay periods rather than making a lump sum at year-end. This ensures consistent cash flow management and avoids accidentally exceeding the cap if employer contributions are higher than expected. Review your arrangement annually because the SG rate changes over time (it increased to 11.5% on 1 July 2024 and is legislated to reach 12% by 1 July 2025). This calculator uses 2024-25 ATO individual tax brackets including the 2% Medicare Levy, and accounts for the $30,000 concessional cap and Division 293 thresholds.
