What Is Salary Sacrifice Australia? A Plain Explanation of Gross Pay, Super, and Tax

What Is Salary Sacrifice Australia?

Salary sacrifice is a way to swap part of your pre-tax pay for a benefit. It is also called salary packaging. Instead of receiving all your gross salary as cash, you agree to have some of it used to pay for things like extra super, a car, or a laptop. The sacrificed amount is not counted as your taxable income, so you pay less tax. But the benefit may be subject to fringe benefits tax (FBT) unless it is exempt.

This article explains how salary sacrifice works with gross pay, super, and tax, using the latest Australian rules from the Fair Work Ombudsman, the Australian Bureau of Statistics, and the ATO.

How Salary Sacrifice Affects Your Gross Pay

Your gross pay is the total amount you earn before tax and other deductions. When you salary sacrifice, your gross pay stays the same on paper, but your employer diverts part of it to the benefit. Your taxable income becomes your gross pay minus the sacrificed amount.

For example, if your annual salary is $80,000 and you sacrifice $5,000 into super, your taxable income is $75,000. You pay tax on $75,000, not $80,000. The $5,000 goes into your super fund and is taxed at 15% (if within the concessional cap).

Your employer still pays the super guarantee on your reduced salary. The super guarantee rate is 12% from 1 July 2026. So on a $75,000 salary, the employer contributes $9,000. Combined with your $5,000 sacrifice, total super contributions are $14,000.

Salary Sacrifice and the Salary Index

The Salary Index measures your gross ordinary-time earnings against the national line of 100. For 2026, the national line is $108,352 per year (based on ABS Average Weekly Earnings). Salary sacrifice does not change your gross pay for index purposes—the index uses your full-time adult ordinary-time earnings before any sacrifice. But your take-home pay and tax are affected.

If you are on the national minimum wage ($26.44/hr, index 48.2), salary sacrifice is unlikely because your pay is already low. Awards and enterprise agreements often set minimum cash pay that cannot be reduced below the award rate.

Tax Benefits of Salary Sacrifice

Salary sacrifice reduces your taxable income, which can move you into a lower tax bracket. The 2026–27 resident tax rates (excluding Medicare) are:

• Nil up to $18,200
• 15% from $18,201 to $45,000
• 30% from $45,001 to $135,000
• 37% from $135,001 to $190,000
• 45% above $190,000

Medicare levy is 2% of taxable income. For a person earning $100,000 and sacrificing $10,000 into super, the tax savings are:

• Tax on $90,000: $5,092 + 30% of ($90,000 - $45,000) = $5,092 + $13,500 = $18,592. Plus Medicare 2% = $1,800. Total tax $20,392. Without sacrifice: tax on $100,000: $5,092 + 30% of ($100,000 - $45,000) = $5,092 + $16,500 = $21,592. Medicare $2,000. Total $23,592. Saving $3,200.

But the sacrificed $10,000 is taxed at 15% inside super ($1,500), so net saving is $1,700. Plus the super grows for retirement.

Super Guarantee and Salary Sacrifice

The super guarantee is 12% of your ordinary-time earnings (from 1 July 2026). Salary sacrifice reduces the base for the guarantee, so your employer pays less super. However, you can sacrifice extra to make up the difference. The maximum contribution base for the guarantee is $270,830.

Concessional contributions (including employer guarantee and salary sacrifice) are capped at $30,000 for 2026–27. Exceeding the cap incurs additional tax.

Common Salary Sacrifice Benefits

• Super: Most common. Reduces tax and boosts retirement savings.
• Car: Novated lease. The lease payments come from pre-tax salary, but FBT may apply.
• Electronic devices: Laptops, tablets, phones for work use.
• Parking: If at or near work, may be FBT-exempt.
• Not-for-profit sector: Up to $15,900 per year in fringe benefits can be tax-free (for public benevolent institutions).

What Salary Sacrifice Does Not Change

• Your award or minimum wage entitlement: You cannot sacrifice below the award rate.
• Your gross pay for the Salary Index: The index uses your ordinary-time earnings before sacrifice.
• Your Medicare levy: Still 2% of taxable income.
• Your HELP repayment: Based on your repayment income, which includes sacrificed amounts for some purposes.

State and Industry Context

Salary sacrifice is more common in certain industries. For example, health care and social assistance has an index of 97.8, and many hospitals offer salary packaging. Education and training (index 105.5) also offers it. In professional, scientific and technical (index 114.7), salary sacrifice for super is common.

State differences in average earnings (e.g., ACT index 109.9, TAS 88.6) do not directly affect salary sacrifice rules, but higher earners benefit more from tax savings.

How to Start Salary Sacrifice

1. Check your employment contract or award. Some awards allow salary sacrifice only for certain benefits.
2. Ask your employer if they offer salary packaging.
3. Choose a benefit and sign a salary sacrifice agreement.
4. Understand the FBT implications. Your employer may pass on the FBT cost.
5. Keep track of your concessional super cap.

Summary

Salary sacrifice is a legitimate way to reduce your tax and boost super, but it is not for everyone. It works best if you are in a higher tax bracket and your employer offers it. Always check the impact on your take-home pay, super, and any FBT. Use the Salary Index to see where your gross pay sits nationally, and remember that salary sacrifice does not change that figure—only your tax and super.
