How Salary Sacrifice Tax Works Across Australian States and Industries
Learn how salary sacrifice tax interacts with state and industry pay differences in Australia. See how your earnings compare to the national line and what it means for tax savings.
Salary sacrifice tax depends on your taxable income, which varies by state and industry; the national line is 100 (annualised $108,352).
How Salary Sacrifice Tax Works Across Australian States and Industries
Salary sacrifice tax is a way to reduce your taxable income by swapping part of your salary for benefits. In Australia, the rules are set by the ATO and Fair Work, but how much you can benefit depends on your earnings—and those earnings vary significantly by state and industry. The Salary Index shows where your pay sits against the national line of 100, which equals full-time adult ordinary-time earnings of $108,352 per year (based on ABS Average Weekly Earnings, May 2026).
What Is Salary Sacrifice Tax?
Salary sacrifice means you agree with your employer to take a lower gross salary in return for a benefit. Common benefits include extra superannuation contributions, a car (via novated lease), or other fringe benefits. The sacrificed amount is not subject to PAYG withholding, so your taxable income drops. However, the benefit may attract fringe benefits tax (FBT) unless it's an exempt benefit like super within the concessional cap. The tax saving comes from paying less income tax on the sacrificed amount, but the benefit itself may be taxed differently.
State Differences in Earnings and Salary Sacrifice
Your ability to salary sacrifice effectively depends on your marginal tax rate. Higher earners save more per dollar sacrificed because they avoid higher bracket tax. The states page shows how average earnings differ across Australia:
- ACT (index 109.9, annualised $119,090) and WA (106.9, $115,825) have the highest average earnings. Workers here are more likely to be in the 37% or 45% tax brackets, making salary sacrifice into super very attractive. For example, a WA miner on $115,825 sacrificing $10,000 into super saves $3,700 in tax (37% + 2% Medicare) minus 15% contributions tax = $2,200 net saving.
- TAS (index 88.6, $96,008) and SA (94.6, $102,450) have lower average earnings. A Tasmanian worker on $96,008 is in the 30% bracket (up to $135,000). Sacrificing $10,000 saves $3,200 minus $1,500 = $1,700. Still worthwhile, but less.
- NSW (101.2, $109,658) and VIC (98, $106,137) sit near the national line. Many workers straddle the 30% and 37% thresholds, so salary sacrifice can help them stay below a higher bracket.
State differences also affect the types of salary sacrifice offered. In WA and ACT, where mining and public service dominate, salary packaging (including cars and novated leases) is common. In TAS, where accommodation and food services are larger, fewer employers offer such benefits.
Industry Differences and Salary Sacrifice
Industry earnings vary even more. The industries page shows:
- Mining (index 154.7) – average $167,600 annualised. Workers here often have high marginal rates (45% plus Medicare). Salary sacrifice into super is highly beneficial. They may also sacrifice for cars or housing in remote areas (FBT concessions apply).
- Professional, scientific and technical (114.7, $124,300) – many in 37% bracket. Salary sacrifice for super or novated leases is common.
- Education and training (105.5, $114,300) – teachers often use salary sacrifice for super or laptops (exempt from FBT if work-related).
- Health care and social assistance (97.8, $106,000) – nurses and carers may sacrifice into super, but lower pay limits the benefit.
- Retail trade (75.9, $82,200) and Accommodation and food services (72.5, $78,600) – workers here are often in the 15% or 30% brackets. Salary sacrifice may still help, but the net saving is smaller. Also, many are casual or part-time, and awards may restrict salary sacrifice.
How the Salary Index Helps You Compare
The how the index works page explains that your salary index is your yearly gross divided by the national line ($108,352) times 100. For example, a retail worker on $82,200 has an index of 75.9. That means their earnings are about 76% of the national average. When considering salary sacrifice tax, a lower index means a lower marginal rate, so less tax saved per dollar sacrificed. Conversely, a mining worker with an index of 154.7 has a high marginal rate and more to gain.
Practical Example: Salary Sacrifice Across States and Industries
Consider two workers:
- Alex in WA, mining industry, annual salary $115,825 (index 106.9). Marginal rate 37% plus 2% Medicare = 39%. Alex salary sacrifices $15,000 into super. Tax saved: $5,850. Super contributions tax (15%): $2,250. Net saving: $3,600. Alex also gets 12% super guarantee on the reduced salary ($100,825), so employer super drops by $1,800, but overall super balance still grows.
- Bailey in TAS, retail trade, annual salary $82,200 (index 75.9). Marginal rate 30% plus 2% = 32%. Bailey sacrifices $5,000 into super. Tax saved: $1,600. Contributions tax: $750. Net saving: $850. The benefit is smaller, but still worthwhile.
Tax Brackets and Medicare
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. Add 2% Medicare levy. Salary sacrifice reduces your taxable income, potentially dropping you into a lower bracket. For example, if you earn $140,000 (just above the 37% threshold), sacrificing $10,000 brings you to $130,000 (30% bracket), saving 7% plus Medicare on that slice.
Super Guarantee and Caps
From 1 July 2026, the super guarantee is 12% on your ordinary time earnings. If you salary sacrifice, your ordinary time earnings (OTE) may be reduced, so your employer's super contribution decreases. However, your total super (employer plus your salary sacrifice) can still be higher. The concessional contributions cap is $27,500. If you exceed it, the excess is taxed at your marginal rate. High earners in mining or professional services need to watch this cap.
Other Benefits and FBT
Salary sacrifice for non-super benefits (e.g., car, school fees) is subject to FBT, which the employer pays. The employer may pass the FBT cost to you via a lower salary. Some benefits are exempt from FBT, like portable electronic devices for work, or super. The pay guides can help you understand award conditions that may affect salary sacrifice.
Key Takeaways
- Salary sacrifice tax savings are larger for higher earners, which tend to be in WA, ACT, and mining or professional industries.
- Lower earners in TAS, retail, or hospitality still benefit, but less.
- Always consider the super cap and the impact on employer super contributions.
- Salary sacrifice is not a one-size-fits-all; your state and industry influence how much you can gain.

Questions people ask
What is salary sacrifice tax?
Salary sacrifice tax refers to the tax treatment of an arrangement where you give up part of your salary in exchange for benefits like extra super contributions, a car, or other fringe benefits. The sacrificed amount is not included in your assessable income for PAYG purposes, reducing your taxable income. However, the benefit may be subject to fringe benefits tax (FBT) unless it's an exempt benefit like additional super within the concessional cap. The net tax saving depends on your marginal tax rate and the type of benefit.
How does salary sacrifice affect my take-home pay?
Salary sacrifice reduces your gross salary, so your take-home pay (after tax) may decrease, but you receive a non-cash benefit instead. For example, if you salary sacrifice $10,000 into super, your taxable income drops by $10,000. At the 30% marginal rate plus 2% Medicare levy, you save $3,200 in tax, but the super contribution is taxed at 15% ($1,500), so net tax saving is $1,700. Your take-home pay is lower by the amount sacrificed, but your super balance grows. For non-super benefits, FBT may apply, so the net benefit varies.
Are there limits on salary sacrifice?
Yes. For super, the concessional contributions cap is $27,500 per year (2026-27). Amounts above that are taxed at your marginal rate plus an excess contributions charge. For other benefits, there is no dollar cap, but FBT applies and the employer may have policies. Also, you cannot salary sacrifice below the national minimum wage or your award rate. The super guarantee (12% from 1 July 2026) is calculated on your reduced salary, so you may get less employer super if you sacrifice salary.
