ADF Salary Sacrifice: How It Affects Your Pay Compared to the National Index
Understand ADF salary sacrifice when reading job ads. See how it changes your take-home pay and where your gross earnings sit on the Australian Salary Index.
The exact index figure for ADF roles is uncertain because the reference does not list Defence Force pay, but salary sacrifice reduces taxable income without changing the gross earnings used for the index.
What Is ADF Salary Sacrifice?
ADF salary sacrifice is an arrangement where Australian Defence Force members agree to forgo part of their pre-tax salary in exchange for certain benefits. Common examples include novated car leases, laptop purchases, or additional superannuation contributions. The sacrificed amount is deducted from your gross pay before tax is calculated, lowering your taxable income and potentially reducing the tax you owe.
When you read a job ad for an ADF role, you might see a base salary plus a mention of salary sacrifice options. This is not extra pay—it is a way to structure your existing pay. The gross salary advertised is still the figure used for the Salary Index, which measures full-time adult ordinary-time earnings. The index does not change because of salary sacrifice.
How the Salary Index Works
The Salary Index sets the national line at 100, which equals $108,352 per year (based on ABS Average Weekly Earnings of $2,083.70 per week, May 2026). Your personal index is your yearly gross salary divided by $108,352, multiplied by 100. For example, if your gross salary is $80,000, your index is 74. If it is $120,000, your index is 111.
Salary sacrifice does not alter your gross salary for index purposes. The index uses the figure before any deductions, including salary sacrifice. So when comparing job offers, always start with the gross annual salary. Then factor in salary sacrifice to estimate your take-home pay.
Reading a Job Ad with Salary Sacrifice
Imagine you see an ADF job ad offering a gross salary of $95,000 with access to salary sacrifice. To compare this with a civilian role, you need to understand two things: the index and the net effect.
First, calculate the index: $95,000 ÷ $108,352 × 100 = 87.7. That is below the national average but above the retail trade index of 75.9 and accommodation index of 72.5. It is also well above the national minimum wage index of 48.2.
Second, estimate take-home pay. Suppose you salary sacrifice $15,000 for a car. Your taxable income becomes $80,000. Using 2026–27 resident tax rates (with tax-free threshold and 2% Medicare levy), your tax would be approximately:
- $0 on first $18,200
- 15% on next $26,800 ($4,020)
- 30% on next $35,000 ($10,500) Total tax $14,520, plus Medicare $1,600 (2% of $80,000) = $16,120. Take-home pay $80,000 – $16,120 = $63,880. Without salary sacrifice, on $95,000 taxable income, tax would be higher: $0 + $4,020 + $30% on $71,800 ($21,540) = $25,560, plus Medicare $1,900 = $27,460, take-home $67,540. So salary sacrifice reduces take-home by about $3,660, but you gain the car benefit.
Comparing Across States and Industries
The states page shows how average earnings vary. For example, NSW index is 101.2, WA 106.9, and ACT 109.9. If your ADF role is based in Canberra, your gross salary might be higher due to allowances, but the index comparison still uses gross pay. The industries page shows mining at 154.7 and professional services at 114.7. ADF pay is not listed, but you can use these benchmarks to see where a typical ADF salary sits.
Super and Tax Considerations
From 1 July 2026, the super guarantee is 12% on earnings up to $270,830. Salary sacrifice can affect super if you sacrifice into super—those contributions are in addition to the mandatory 12%. But if you sacrifice for a car, your employer’s super contribution is based on your reduced salary (the amount after sacrifice), which could lower your super balance over time. Check your employment contract.
Tax brackets for 2026–27: nil up to $18,200; 15% to $45,000; 30% to $135,000; 37% to $190,000; 45% above. Medicare levy is 2%. Salary sacrifice reduces your taxable income, potentially dropping you into a lower bracket.
Practical Tips for Job Ads
- Always look for the gross annual salary. That is the number for the index.
- If the ad says “salary sacrifice available”, ask for the gross figure and the maximum sacrifice amount.
- Use the how the index works page to calculate your own index.
- Compare with award minima: the national minimum wage is $26.44 per hour, $52,255 per year (index 48.2). Entry-level award floor is $25.74 per hour. ADF roles typically pay above these, but the exact rate depends on rank and service.
Final Word
ADF salary sacrifice is a useful tool for managing tax, but it does not change your position on the Salary Index. When reading a job ad, focus on the gross salary first. Then decide if the sacrifice benefits are worth the reduction in take-home pay. For more context, browse our topics page on salary packaging and Defence Force remuneration.
Questions people ask
Does ADF salary sacrifice change my Salary Index number?
No. The Salary Index is based on your gross ordinary-time earnings before any salary sacrifice deductions. So if your gross salary is $90,000, your index is 83 (90,000 ÷ 108,352 × 100), even if you salary sacrifice $15,000 for a car. The index reflects your total remuneration, not your taxable income.
How do I compare two job offers when one includes salary sacrifice?
Compare the gross annual salaries first. That is the number used for the index. Then estimate your take-home pay after salary sacrifice and tax. For example, a $95,000 salary with a $10,000 sacrifice gives a taxable income of $85,000. Use the 2026–27 tax rates (nil up to $18,200, then 15%, 30%, etc.) plus 2% Medicare levy to see the net difference. Remember that salary sacrifice can also reduce your super guarantee if the sacrifice is taken from pre-tax pay.
Is ADF salary sacrifice always worth it?
It depends on your personal situation. Salary sacrifice reduces your taxable income, which can lower your tax bill. But it also reduces the amount your employer pays into super (if the sacrifice is from pre-tax salary). You also lose access to that cash for other expenses. Compare the benefit of the sacrificed item (e.g., a car lease) against the tax saved. Use the national minimum wage of $52,255 (index 48.2) as a floor to see if the offer is above award.
