Salary Sacrifice Home Loan: How State and Industry Pay Differences Affect Your Arrangement
Understand how salary sacrifice home loan interacts with state and industry pay differences in Australia. The salary index remains unchanged, but your capacity to sacrifice varies.
Salary sacrifice for a home loan does not alter the gross earnings used for the salary index, so the index for a worker depends on their state and industry benchmarks.
What Is Salary Sacrifice Home Loan?
Salary sacrifice home loan is an arrangement where you agree to forgo part of your pre-tax salary in exchange for your employer making payments towards your home loan. It is not a standard benefit in Australia, unlike salary sacrifice for superannuation or a car. The key idea is that by reducing your taxable income, you may pay less tax, but the arrangement must comply with tax laws and Fringe Benefits Tax (FBT) rules. The salary index, which measures full-time adult ordinary-time earnings, is based on your gross pay before any sacrifice, so your index remains the same regardless of whether you salary sacrifice.
State Pay Differences and Salary Sacrifice
Your ability to enter a salary sacrifice home loan arrangement depends partly on your gross earnings, which vary significantly by state. The Salary Index shows the national line at 100, with states ranging from Tasmania at 88.6 to the ACT at 109.9. For example, a worker in Western Australia (index 106.9) has a higher typical gross salary than one in South Australia (index 94.6). A higher gross salary means more headroom to sacrifice without falling below award or minimum wage requirements. However, the arrangement itself is not tied to your state; it is a matter between you and your employer. The states page provides detailed benchmarks for each state.
Example: WA vs TAS
Consider a full-time worker in Western Australia earning the state benchmark of $115,825 annualised (index 106.9). If they salary sacrifice $10,000 towards a home loan, their taxable income drops to $105,825, saving tax at their marginal rate. In Tasmania, the benchmark is $96,008 (index 88.6). The same $10,000 sacrifice would leave $86,008 taxable. While both workers benefit from lower tax, the WA worker has a higher gross base, making the sacrifice more feasible without dipping below award rates. The national minimum wage is $52,255 (index 48.2), so even after sacrifice, both workers remain above that floor.
Industry Pay Differences and Salary Sacrifice
Industry also plays a role. The industries page shows that Mining has an index of 154.7, while Retail trade is 75.9 and Accommodation and food services is 72.5. A mining worker earning around $167,600 annualised (154.7% of $108,352) has substantial capacity to sacrifice part of their salary for a home loan. In contrast, a retail worker earning about $82,200 (75.9% of $108,352) has less room. The how the index works page explains that these are gross ordinary-time benchmarks, not individual pay offers.
Example: Mining vs Retail
A mining professional in Queensland (state index 97.9, but industry index 154.7) might earn well above the national line. If they sacrifice $20,000, they still have a high residual income. A retail worker in the same state, with an industry index of 75.9, earns much less. Sacrificing even $5,000 could bring them closer to award minima. Modern awards set minimum pay rates; for example, the national minimum wage is $26.44 per hour, and entry-level award floor is $25.74. Salary sacrifice cannot reduce your pay below the applicable award or minimum wage. So industry pay levels directly affect how much you can sacrifice.
Tax and Super Considerations
Salary sacrifice home loan reduces your taxable income, which can lower the tax you pay. For the 2026–27 year, resident tax rates are: nil up to $18,200, 15% on the next bracket, 30% up to $135,000, 37% up to $190,000, and 45% above. The Medicare levy is 2%. If you sacrifice $10,000 and you are in the 30% bracket, you save $3,000 in tax plus $200 Medicare levy, but you also lose that amount from your take-home pay. Importantly, the super guarantee (12% from 1 July 2026) is calculated on your ordinary-time earnings, which may be reduced by salary sacrifice. Check with your employer whether the sacrifice affects your super contributions. The topics page covers more on salary packaging.
Is Salary Sacrifice Home Loan Right for You?
This arrangement is not widely offered. Most employers provide salary sacrifice for super, cars, or laptops. A home loan sacrifice may attract FBT, which your employer may pass on to you. The benefit depends on your marginal tax rate, your employer's willingness, and your overall financial situation. Use the salary index to understand where your pay sits relative to the national line, and consider how state and industry differences affect your capacity to sacrifice. Always consult a tax advisor or your employer's HR department before entering any salary sacrifice agreement.
Key Takeaways
- Salary sacrifice home loan does not change your salary index; it remains based on gross ordinary-time earnings.
- State and industry pay differences affect how much you can sacrifice without breaching award rates.
- Higher-index states (ACT, WA) and industries (Mining, Professional services) offer more room for sacrifice.
- Lower-index states (Tasmania, SA) and industries (Retail, Accommodation) have less headroom.
- Tax savings are real, but super guarantee may be reduced. Seek professional advice.

Questions people ask
Can I salary sacrifice my home loan in Australia?
Salary sacrifice for a home loan is not common and is generally not offered by employers as a standard benefit. Most salary sacrifice arrangements are for superannuation, cars, or other fringe benefits. However, some employers may allow you to sacrifice part of your pre-tax salary to pay for mortgage expenses if they structure it as a fringe benefit, but this is subject to Fringe Benefits Tax (FBT) and employer discretion. Always check with your employer and a tax professional.
How do state pay differences affect salary sacrifice home loan?
State pay differences affect your gross earnings, which determine how much you can potentially sacrifice. For example, a worker in the ACT (index 109.9) earns a higher gross salary than one in Tasmania (index 88.6). A higher gross salary means more room to reduce taxable income through salary sacrifice, but the actual arrangement depends on your employer's policy. The salary index itself does not change with sacrifice; it reflects your ordinary-time earnings before any sacrifice.
Does salary sacrifice affect my super guarantee?
Yes, salary sacrifice can reduce your super guarantee (SG) if the sacrificed amount is part of your ordinary-time earnings. The SG is calculated on your ordinary-time earnings base, which may be reduced by salary sacrifice arrangements. However, the super guarantee rate is 12% from 1 July 2026, and the maximum contribution base is $270,830. If you sacrifice salary for a home loan, your employer's SG contribution may decrease, so consider the overall impact on your retirement savings.
