Salary sacrifice arrangements come up often in conversations about reducing tax. But many people aren’t entirely sure how they actually work, or whether they genuinely make financial sense for their situation. However, understanding the mechanics makes it much easier to judge whether it’s worth setting up.
Salary sacrifice is an arrangement where you agree with your employer to redirect part of your pre-tax salary toward a benefit, most commonly additional superannuation contributions. You receive this instead of regular take-home pay. Consequently, the fund generally taxes the sacrificed amount at a different, often lower, rate than your marginal income tax rate. That’s where the potential benefit comes from.
The fund generally taxes superannuation contributions made through salary sacrifice at a concessional rate. This rate is typically lower than the marginal tax rate many people pay on their income. Therefore, for people on higher marginal tax rates, this difference can result in a genuine tax saving. That’s compared to receiving the same amount as regular salary.
Because the sacrificed amount reduces your taxable salary, you pay less income tax on the remaining portion of your pay. Meanwhile, the sacrificed amount goes into your super fund, where the fund taxes it at the concessional rate instead. Consequently, the overall tax you pay on that portion of your income can end up lower. This compares favourably to simply receiving it as salary and paying your full marginal rate.
Some employers also offer salary sacrifice arrangements for other benefits. These include a work vehicle through a novated lease, additional leave, or certain other approved benefits. However, these arrangements have their own specific tax treatment, including potential fringe benefits tax implications for the employer. The rules differ from straightforward superannuation salary sacrifice.
Superannuation salary sacrifice contributions count toward the concessional contributions cap, along with your employer’s standard superannuation guarantee contributions. Therefore, exceeding this cap can result in additional tax. This reduces or eliminates the benefit of salary sacrificing in the first place, so check your total contributions before committing to an arrangement.
Higher income earners. The tax rate difference between your marginal rate and the concessional super rate tends to be larger. This makes the arrangement more beneficial.
People with a clear retirement savings goal. Since you generally can’t access sacrificed super until retirement, this suits people comfortable locking funds away for the long term.
Those with room under the contributions cap. Confirming you have space under your cap before committing avoids an unexpected tax consequence.
Lower income earners. The tax rate difference may be smaller. In some cases, the concessional rate could even be higher than your marginal tax rate, reducing or eliminating the benefit.
People who need access to cash sooner. Since salary sacrificed super stays locked away until retirement, this isn’t suitable if you need the funds for near-term goals like a home deposit.
Those already near their contribution cap. Adding further sacrificed contributions on top of employer super could trigger excess contributions tax.
The benefit depends heavily on your income, tax bracket, retirement timeline, and existing super contributions. Because of this, it’s worth running the actual numbers for your situation, rather than assuming it’s automatically a good idea.
