What a Salary Sacrifice Second Hand Car Means for Your Pay

What Is a Salary Sacrifice Second Hand Car?

A salary sacrifice second hand car arrangement lets you use part of your pre-tax salary to pay for a car and its running costs. It is typically set up through a novated lease with your employer. The key benefit is that you reduce your taxable income, so you pay less income tax and Medicare levy. However, the arrangement does not change your gross ordinary-time earnings – the figure used to calculate your Salary Index.

When reading a job ad, you might see a mention of salary sacrifice benefits. Understanding how a salary sacrifice second hand car affects your overall pay is essential for comparing offers. The index helps you see where the gross salary sits, but you need to look beyond that to evaluate the net value of the car benefit.

How the Salary Index Works

The Salary Index compares a worker's gross annual ordinary-time earnings to the national line of 100. That line is set at $108,352 per year (based on ABS Average Weekly Earnings, May 2026). For example, a full-time worker earning $90,000 has an index of 83 – meaning they earn 83% of the national average. The index is a useful starting point when comparing job offers, but it does not account for salary sacrifice, tax, or other benefits.

Salary Sacrifice and Your Take-Home Pay

When you enter a salary sacrifice second hand car arrangement, your employer deducts the car costs from your gross salary before tax. This lowers your taxable income. Your take-home pay increases because you pay less tax, but your gross salary (and therefore your index) stays the same.

Example: Comparing Two Offers

Imagine you have two job offers:

• Offer A: $90,000 gross, no salary sacrifice. Index = 83.
• Offer B: $80,000 gross, plus a salary sacrifice second hand car worth $15,000. Index = 74.

At first glance, Offer A looks better. But let's calculate the net effect of Offer B. Assume you are in the 30% marginal tax bracket (taxable income between $45,001 and $135,000 for 2026–27). The $15,000 sacrifice saves you $4,500 in tax (30%) plus $300 Medicare levy (2%), a total of $4,800. So the net cost of the car to you is $15,000 – $4,800 = $10,200. Your effective gross income after considering the car benefit is $80,000 + ($15,000 – $10,200) = $84,800. That is still less than $90,000, but you also have a car. If the car is essential for work or saves you other costs, Offer B might be more attractive.

This example shows why you need to look beyond the index. The index tells you where the gross salary sits, but the net value of a salary sacrifice second hand car can shift the comparison.

Tax and Super Considerations

Salary sacrifice reduces your taxable income, but it may also affect your superannuation guarantee. Your employer pays super on your ordinary time earnings, which can be reduced by salary sacrifice. Check your employment contract to see how the sacrifice is treated. Also, the ATO applies fringe benefits tax (FBT) to the private use of a car provided through salary sacrifice. Some employers absorb the FBT, while others pass it on, reducing the benefit. Always ask about FBT when negotiating a salary sacrifice second hand car.

Using the Index to Compare Offers

When you receive multiple job offers, start by noting the gross salary and calculating the index. Then list any salary sacrifice benefits, such as a car, and estimate their after-tax value. The index gives you a quick benchmark – for instance, a job with an index of 100 is at the national average, while an index of 75 is in retail trade territory. But the index alone cannot tell you which offer leaves you better off.

State and Industry Benchmarks

Your index also varies by location and industry. For example, the average index in Western Australia is 106.9, while in Tasmania it is 88.6. If you are comparing offers in different states, adjust your expectations. Similarly, industries like mining (index 154.7) pay well above the national line, while accommodation and food services (index 72.5) pay below. A salary sacrifice second hand car might be more common in higher-paying industries where employers offer such perks.

FAQs

Can I salary sacrifice a second hand car?

Yes, many employers offer salary sacrifice for a second hand car through a novated lease. The arrangement allows you to use pre-tax income to cover car expenses such as lease payments, fuel, insurance, and maintenance. However, the car must be used for work-related purposes to some extent, and the employer may pass on fringe benefits tax (FBT) for private use. Check with your employer or a tax professional to confirm eligibility.

How does salary sacrifice for a car affect my tax?

Salary sacrifice reduces your taxable income, so you pay less income tax and Medicare levy. For example, if you are in the 30% tax bracket (taxable income between $45,001 and $135,000 in 2026–27), sacrificing $10,000 saves you $3,000 in tax plus $200 Medicare levy (2%), a total of $3,200. The exact saving depends on your marginal tax rate. Note that salary sacrifice does not change your gross ordinary-time earnings, so your Salary Index remains based on your pre-sacrifice salary.

How do I compare two job offers when one includes a salary sacrifice second hand car?

First, compare the gross salaries using the Salary Index to see where each sits against the national line (100 = $108,352 per year). Then estimate the net benefit of the car sacrifice. For example, if Job A offers $90,000 gross (index 83) and Job B offers $80,000 gross (index 74) plus a salary sacrifice second hand car worth $15,000, calculate the tax saving on the sacrificed amount. If you are in the 30% bracket, the net cost of the car is about $10,200 after tax savings. Job B's effective net income may be higher than Job A's, even though the gross is lower. Also consider FBT, running costs, and whether the car is essential for work.
