Salary sacrifice is an arrangement where an employee agrees to forgo part of their before-tax income in exchange for employer contributions or benefits. The most common use in Australia is directing extra contributions into superannuation, boosting retirement savings in a tax-effective way. Since contributions are taken from pre-tax income, they are generally taxed at 15% within the super fund, which is usually lower than most marginal tax rates.
This strategy helps employees reduce taxable income while growing long-term savings. Salary sacrifice agreements must be arranged with the employer and applied prospectively to future earnings.
Advanced
From a technical perspective, salary sacrifice contributions to superannuation are classified as concessional contributions and count toward the annual concessional contribution cap ($27,500 as of 2023–24). These contributions are in addition to compulsory Superannuation Guarantee (SG) payments made by employers.
While highly tax-effective, salary sacrifice may not suit everyone. High-income earners may be subject to Division 293 tax, which applies an extra 15% on concessional contributions. Salary sacrifice arrangements must also comply with employment and tax rules, and once contributed, funds are preserved in super until retirement age or a condition of release is met.

Metrics
- Annual concessional contributions compared to the cap
- Tax savings achieved versus marginal tax rate
- Growth of superannuation balance over time
- Net benefit after fees, taxes, and lost take-home pay
Issues

Example
An employee on $90,000 arranges to salary sacrifice $10,000 into superannuation. Instead of being taxed at their marginal rate of 34.5%, the contribution is taxed at 15% within the fund. This reduces taxable income, provides immediate tax savings, and boosts retirement savings.
