How Australia Salary Sacrifice Affects Your Pay by State and Industry
Learn how Australia salary sacrifice can reduce your taxable income differently depending on your state and industry. Compare average earnings indices and see how sacrifice arrange
Salary sacrifice is not a pay figure; the salary index benchmarks earnings before sacrifice, so the potential benefit varies by state and industry based on average earnings relative to the national line.
How Australia Salary Sacrifice Works
Salary sacrifice is an arrangement where you agree to forgo part of your pre-tax salary in exchange for benefits such as additional superannuation contributions, a car, or other non-cash items. This reduces your taxable income, so you pay less income tax and Medicare levy. The Salary Index benchmarks full-time adult ordinary-time earnings at 100, which is $108,352 per year (based on ABS Average Weekly Earnings, May 2026). Your salary sacrifice potential is tied to how your earnings compare to this national line.
State Differences in Salary Sacrifice
Because average earnings vary by state, the amount you can realistically sacrifice also differs. For instance, the Australian Capital Territory has the highest state index at 109.9 ($119,090 annualised), while Tasmania is the lowest at 88.6 ($96,008). A worker in the ACT earning near the state average has more pre-tax income to redirect into super or other benefits than a worker in Tasmania on the state average. However, the tax savings from salary sacrifice are the same percentage – it’s the marginal tax rate that matters. For 2026–27, the tax rates are: nil up to $18,200, 15% to $45,000, 30% to $135,000, 37% to $190,000, and 45% above. A worker in a higher tax bracket saves more per dollar sacrificed. For state-by-state benchmarks, see states.
Industry Differences in Salary Sacrifice
Industry average earnings vary even more. Mining has the highest industry index at 154.7, meaning average earnings are about 55% above the national line. A mining worker on that average could sacrifice a significant portion of salary into super, reducing taxable income from a high marginal rate. In contrast, retail trade (index 75.9) and accommodation and food services (index 72.5) have average earnings well below the national line. A retail worker on the industry average may have less room to sacrifice, and the tax saving is smaller because they are likely in a lower tax bracket. For a full list of industry indices, see industries.
Practical Example
Consider two workers: one in mining earning $160,000 per year (index ~148) and one in retail earning $52,000 per year (index ~48). The mining worker can sacrifice up to the concessional super cap ($30,000 in 2026–27) and save tax at the 37% marginal rate (plus 2% Medicare levy). The retail worker may sacrifice a smaller amount, say $5,000, and save tax at the 30% marginal rate. The mining worker’s tax saving is larger both in dollars and as a percentage. However, the retail worker still benefits from reduced taxable income and lower tax, but the sacrifice is still worthwhile.
How the Salary Index Helps
The how the index works page explains that the index is your yearly gross divided by the national line ($108,352) times 100. If your salary is above 100, you are above the national average; if below, you are below. This helps you gauge your potential for salary sacrifice. For example, if your salary index is 120, you earn 20% above average, giving you more headroom to sacrifice.
Important Considerations
Salary sacrifice is not a one-size-fits-all. Your award or enterprise agreement may set limits. The super guarantee is 12% from 1 July 2026, and salary sacrifice contributions count toward the concessional cap. Also, the Medicare levy (2%) applies, but salary sacrifice reduces your levy because it lowers your taxable income. Take-home pay estimates on this site ignore salary sacrifice, so your actual take-home may be lower if you sacrifice, but your tax saved is real.
Summary
Whether you are in a high-index state like Western Australia (index 106.9) or a low-index industry like Tasmania (88.6), salary sacrifice can be a smart way to boost super or get a car. Use the Salary Index to see where your pay sits, and check your industry and state benchmarks to understand your potential.
Questions people ask
Does the benefit of salary sacrifice vary by state in Australia?
Yes, because average earnings differ by state. For example, Western Australia has a salary index of 106.9 (annualised $115,825), while Tasmania has an index of 88.6 ($96,008). A worker in WA may have more room to sacrifice salary into super or other benefits than a worker in TAS, simply because their gross pay is higher. However, the tax rules for salary sacrifice are national, so the marginal tax rate benefit is the same regardless of state. The key difference is the amount of salary available to sacrifice.
How does salary sacrifice affect take-home pay in different industries?
Industries with higher average earnings, like mining (index 154.7) and professional services (index 114.7), allow workers to sacrifice larger amounts into super or other benefits, reducing their taxable income more significantly. In contrast, industries like retail trade (index 75.9) and accommodation and food services (index 72.5) have lower average earnings, so the scope for salary sacrifice is smaller. The take-home pay impact also depends on your marginal tax rate: a mining worker on a higher rate saves more tax per dollar sacrificed than a retail worker on a lower rate.
Can I salary sacrifice into superannuation in any industry?
Yes, salary sacrifice into super is available to most employees across all industries, provided your employer offers it and you meet the ATO rules. However, the amount you can sacrifice is limited by your total super contributions (concessional cap) and your employer's policy. In industries with higher average earnings, you may be able to sacrifice more without exceeding the cap. Always check your award or enterprise agreement, as some may restrict salary sacrifice arrangements.
