Max Salary Sacrifice on Award Wages: What's the Limit?

What is max salary sacrifice?

Max salary sacrifice refers to the highest amount of pre-tax pay you can legally forgo in exchange for benefits like extra superannuation, a car, or other fringe benefits. In Australia, salary sacrifice is common, but it has limits – especially for employees covered by awards or the national minimum wage. This guide explains how the max salary sacrifice interacts with award wages and the national minimum wage, using the Salary Index as a benchmark for understanding pay levels.

Awards vs national minimum wage: the baseline

Australia's pay system has two key floors: the national minimum wage and modern award rates. From 1 July 2026, the national minimum wage is $26.44 per hour, or $1,004.90 per week, giving an annualised $52,255 and a Salary Index of 48.2. Award rates are generally higher – they rose by 4.75% from 1 July 2026. For example, the Retail Trade industry index is 75.9, while Accommodation and Food Services sits at 72.5. These figures show that award-covered workers typically earn more than the minimum, but still well below the national line of 100 (full-time adult ordinary-time earnings of $108,352).

When you salary sacrifice, you cannot reduce your cash pay below the applicable minimum. If you're on an award, your base rate of pay (before sacrifice) must be at least the award rate. After sacrifice, your cash pay must still meet that award rate. This is a critical limit on your max salary sacrifice.

How salary sacrifice interacts with award pay

Salary sacrifice is an agreement between you and your employer. For award-covered employees, the Fair Work Ombudsman says salary sacrifice cannot reduce your entitlements under the award. That means your ordinary hourly rate, overtime, penalties, and allowances must be calculated on your full pre-sacrifice wage. The sacrifice only affects the amount you actually receive in cash.

So, what is your max salary sacrifice? It depends on two things: the type of benefit and the award floor. For superannuation, the concessional contributions cap is the main limit. For other benefits like cars or laptops, there are FBT caps and rules. But the award floor often bites first. If your award rate is $30/hr and you earn $35/hr, you could sacrifice up to $5/hr into super – as long as your cash pay stays at $30/hr. But if you earn exactly the award rate, you cannot sacrifice any cash without dropping below it. In that case, your max salary sacrifice is zero for cash-based benefits.

Examples of max salary sacrifice on awards

Let's look at concrete examples using the industries data. Suppose you work in Retail Trade (index 75.9). The average weekly earnings in that industry are lower than the national line. If you're on the General Retail Industry Award, your minimum hourly rate might be around $25-$28 depending on classification. If you earn $30/hr, you could sacrifice up to $2-$5/hr into super, but no more than the concessional cap allows. Your cash pay after sacrifice must still be at least the award rate.

Another example: a hospitality worker in Accommodation and Food Services (index 72.5). The award rate for a casual employee might be $27-$30/hr including casual loading. If you're casual, your max salary sacrifice is limited because your cash pay must cover the award rate plus loading. Sacrificing too much could leave you below the minimum.

For a professional in Professional, Scientific and Technical Services (index 114.7), award coverage is less common, but if you are on an award, the same rules apply. Higher earners have more room to sacrifice because their pay is well above the award floor.

Limits and caps beyond awards

Even if you have room above the award rate, the max salary sacrifice is capped by tax rules. For super, the concessional contributions cap (including employer super guarantee) is the key limit. The super guarantee is 12% from 1 July 2026, with a maximum contribution base of $270,830. So if your salary is above that base, your employer only pays super on the first $270,830. Your salary sacrifice into super counts towards the concessional cap. The exact cap figure for 2026-27 is not in our reference; check the ATO. For other benefits, there are FBT caps and reporting requirements.

Also, salary sacrifice can affect your how the index works because it reduces your gross taxable income, but the Salary Index uses gross ordinary-time earnings before sacrifice. So your index figure (your pay divided by the national line) stays the same – sacrifice doesn't change your base pay, only your cash flow.

Tax and super considerations

Salary sacrifice reduces your taxable income, so you pay less income tax and Medicare levy. For 2026-27, resident tax rates (excluding Medicare) are: nil to $18,200; 15% to $45,000; 30% to $135,000; 37% to $190,000; 45% above. Plus 2% Medicare levy. If you sacrifice into super, the contributions are taxed at 15% within the fund (if within the cap), which is often lower than your marginal rate. This can boost your retirement savings.

But remember: salary sacrifice does not reduce your super guarantee – your employer still pays 12% on your ordinary time earnings (including the sacrificed amount). That's a benefit.

Conclusion

Your max salary sacrifice depends on your award or minimum wage floor, the type of benefit, and tax caps. For award-covered workers, the award rate is the hard lower bound. To find your personal limit, check your pay guides and award classification, then consider the concessional super cap. The states also have different average earnings, but award rates are national. Always consult the Fair Work Ombudsman or a tax professional before setting up a salary sacrifice arrangement.
