How a salary sacrifice car lease affects your pay index by state and industry
Learn how a salary sacrifice car lease changes your take-home pay and pay index, with state and industry differences based on Australian earnings benchmarks.
A salary sacrifice car lease does not have a single index figure; its effect depends on your gross earnings, tax bracket, and state or industry earnings level.
What is a salary sacrifice car lease?
A salary sacrifice car lease is an arrangement where you give up part of your pre-tax salary in exchange for a car lease. Your employer pays the lease and running costs from your gross salary before tax is taken out. This reduces your taxable income, so you pay less income tax. However, the Australian Tax Office applies fringe benefits tax (FBT) to the private use of the car, which can reduce the savings. The net benefit depends on your income, the car's value, and how much you use it for work.
How does it affect your pay index?
The Salary Index measures gross ordinary-time earnings, not take-home pay. When you enter a salary sacrifice car lease, your gross salary drops because you are swapping cash for a non-cash benefit. Your index number therefore falls. For instance, if you earn the national line of $108,352 (index 100) and sacrifice $20,000 for a car, your gross earnings become $88,352, giving an index of about 81.5. That looks like a pay cut on the index, but your take-home pay may actually rise because the tax saved can outweigh the FBT cost. The index is a benchmark for comparing earnings, not a measure of living standards. To understand how your own situation stacks up, see how the index works.
State differences
Your state matters because average earnings vary, and that affects the potential tax saving from a salary sacrifice car lease. In states with higher average earnings, more people are in the 37% or 45% tax brackets (2026–27 rates: 30% up to $135,000, 37% up to $190,000, 45% above). The higher your marginal rate, the more you save per dollar sacrificed. For example:
- ACT (index 109.9, annualised $119,090): Many workers earn above $135,000, so a salary sacrifice car lease can save 37 cents or more in tax per dollar sacrificed.
- WA (index 106.9, $115,825): Similarly high earnings, strong benefit.
- NSW (index 101.2, $109,658): Close to the national line, moderate benefit.
- TAS (index 88.6, $96,008): Lower earnings mean more people are in the 30% bracket, so savings are smaller.
Even if you live in a lower-earning state, a salary sacrifice car lease can still be worthwhile, especially if you have a high personal income. Check the states page for your local earnings benchmark.
Industry differences
Your industry also shapes the value of a salary sacrifice car lease. Industries with high average earnings give you more tax headroom. Using the index benchmarks:
- Mining (index 154.7): Very high earnings. Many employees are in the top tax bracket, so sacrificing salary for a car can save up to 45 cents per dollar (plus Medicare levy).
- Professional, scientific and technical services (index 114.7): Above-average earnings, strong benefit.
- Education and training (index 105.5): Slightly above the national line, moderate benefit.
- Health care and social assistance (index 97.8): Near the national line, benefit depends on your role.
- Retail trade (index 75.9) and Accommodation and food services (index 72.5): Lower earnings, so the tax saving is smaller. For someone on the national minimum wage ($52,255, index 48.2), salary sacrifice may not make sense because the tax saved is low and FBT could eat it up.

Other considerations
A salary sacrifice car lease interacts with superannuation and tax. From 1 July 2026, the super guarantee is 12% on ordinary time earnings. Some employers calculate super on your reduced salary after sacrifice, which could lower your super contributions. Others use the pre-sacrifice amount – check your contract. Also, the FBT rules are complex. A common way to reduce FBT is to use the car mainly for work (e.g., keep a logbook). If FBT applies, your employer may pass the cost to you, reducing your take-home benefit.
Your take-home pay estimate from the index assumes no salary sacrifice. For a resident using the tax-free threshold and 2% Medicare levy, a gross $108,352 would net about $78,000. With a $20,000 salary sacrifice car lease, your taxable income drops to $88,352, netting about $65,000 plus the car benefit. The exact figure depends on FBT and your employer's arrangement. Always consult a tax professional.

Summary
A salary sacrifice car lease can boost your take-home pay by reducing tax, but it lowers your gross earnings and therefore your pay index. The benefit is largest in high-earning states like ACT and WA, and in high-earning industries like mining and professional services. In lower-earning states and industries, the savings are smaller. Use the Salary Index to see where your gross earnings sit, but remember that salary sacrifice changes the picture. Always consider FBT, super, and your personal tax bracket before signing up.
Questions people ask
Does a salary sacrifice car lease reduce my pay index?
Yes, because the index measures gross ordinary-time earnings. If you salary sacrifice part of your salary for a car lease, your gross earnings drop, so your index number falls. For example, someone earning the national line of $108,352 (index 100) who sacrifices $20,000 would have gross earnings of $88,352, an index of about 81.5. However, the benefit is in take-home pay, which may increase due to lower tax, depending on FBT and your tax bracket.
Is a salary sacrifice car lease available in all states?
Yes, the arrangement is available across Australia, but its value varies by state because earnings differ. In states with higher average earnings, such as the ACT (index 109.9) or WA (index 106.9), employees are more likely to be in higher tax brackets, making the tax savings from salary sacrifice larger. In lower-earning states like Tasmania (index 88.6), the benefit is smaller. Always check your state's specific rules and your employer's policy.
Which industries benefit most from a salary sacrifice car lease?
Industries with higher average earnings see the greatest benefit because the tax savings increase with income. For example, mining (index 154.7) and professional, scientific and technical services (index 114.7) have high earnings, so employees there can save more tax by sacrificing salary for a car. In contrast, retail trade (index 75.9) and accommodation and food services (index 72.5) have lower earnings, so the tax advantage is smaller. Your individual circumstances, including FBT and the type of car, also matter.
