How a car salary sacrifice affects your take-home pay when comparing job offers
Pay varies by employer and arrangement; the ATO example shows a $65,000 salary with a car sacrifice can increase net disposable income by about $1,681 per year with employee contributions.
Comparing job offers: look at what reaches your bank account
When you're weighing up a job offer, the headline salary can be misleading. What matters is the amount that lands in your bank account after tax, the Medicare levy, and any salary sacrifice arrangements. A car salary sacrifice is a common way to reduce your taxable income, but it comes with rules that can change your take-home pay in unexpected ways.
How salary sacrifice works
Salary sacrifice (also called salary packaging) is an agreement with your employer to swap part of your pre-tax salary for benefits. The Australian Taxation Office explains that this reduces your taxable income, so you pay less income tax. Common benefits include cars, school fees, and childcare costs. Your employer may have to pay fringe benefits tax (FBT) on the value of the benefit, which can affect how much you save.
For a car, the ATO provides a detailed example. Sam earns $65,000 a year and sacrifices part of his salary for the use of a $35,000 car with $11,500 in running costs. Without any employee contribution, his taxable income drops to $47,647, and his net disposable income is $41,612. But if he makes an employee contribution of $7,000 (from after-tax pay), his taxable income is $60,855 and net disposable income rises to $43,593 – about $1,681 more than without packaging. The employee contribution reduces the FBT his employer pays, making the arrangement more tax-effective.
What to check when comparing offers
When you see a job ad that includes a car salary sacrifice, don't just compare gross salaries. Use these steps:
- Calculate your taxable income after the sacrifice. The sacrificed amount is deducted from your salary before tax. Use the Take-home pay guide to estimate your tax and Medicare levy.
- Factor in employee contributions. If your employer asks you to make a contribution, that comes out of your after-tax pay. The ATO example shows that a contribution can actually increase your net disposable income.
- Check the FBT implications. From 1 April 2027, work-related items provided through salary sacrifice will no longer be exempt from FBT. This may affect the value of the package.
- Remember super is separate. Your employer must still pay the super guarantee (12% from 1 July 2026) on your ordinary time earnings. The sacrificed amount is an employer contribution to super, but it counts towards the concessional cap of $32,500 per year.
The impact on your take-home pay
Your take-home pay is what remains after income tax and the Medicare levy. For 2026–27, the tax rates are:
- Nil on the first $18,200
- 15c per $1 from $18,201 to $45,000
- 30c per $1 from $45,001 to $135,000
- 37c per $1 from $135,001 to $190,000
- 45c per $1 over $190,000
The Medicare levy is 2% of taxable income for most people, with a shading-in for low incomes. The latest published single-person thresholds are $28,011 and $35,013. Full-time salaries typically pay the full 2%.
A car salary sacrifice lowers your taxable income, so you pay less tax and Medicare levy. But the benefit may be reported on your income statement, which can affect child support, government benefits, or the Medicare levy surcharge.
Example: comparing two offers
Suppose Offer A is $70,000 salary with no packaging. Offer B is $65,000 salary plus a car salary sacrifice (similar to Sam's example). Using the ATO's method, Offer B could give you a higher net disposable income if structured with employee contributions. You'd also save the $11,500 in car running costs. But you'd have a reportable fringe benefit of about $13,208, which might push you into a higher bracket for some means-tested programs.
Use the Salary packaging guide to model your own situation. The Tax and Medicare page has the latest rates.
Key points to remember
- A car salary sacrifice can increase your take-home pay, but only if the arrangement is effective.
- You must agree to the sacrifice before you earn the salary.
- Employee contributions can improve the outcome.
- Super guarantee is calculated on your ordinary time earnings, not the sacrificed amount.
- From 1 April 2027, work-related items lose their FBT exemption.
Always ask the employer for a detailed breakdown of the package, including the car's cost, running expenses, and any employee contribution required. Then compare the net disposable income – the amount that actually reaches your bank account each fortnight.
Questions
Does a car salary sacrifice reduce my super guarantee?
No. Your employer must still pay the super guarantee (12% from 1 July 2026) on your ordinary time earnings as if you had not sacrificed salary. The sacrificed amount is an employer contribution to super, but it counts towards your concessional cap. Check that your employer is not using the sacrifice to reduce their super obligation.
What is fringe benefits tax (FBT) and how does it affect me?
FBT is paid by your employer on most packaged benefits, including a car. The taxable value is calculated using a statutory formula (20% of the car's cost in the ATO example). Your employer may ask you to make an employee contribution (from after-tax pay) to reduce their FBT liability. This contribution lowers the fringe benefit and can increase your net disposable income.
How do I compare two job offers when one includes a car salary sacrifice?
Focus on net disposable income after tax, Medicare levy, and any employee contributions. Use the ATO's example: with a $65,000 salary and a $35,000 car, net disposable income was $43,593 with employee contributions versus $41,912 without packaging. Also consider that the car's running costs are covered, and that reportable fringe benefits may affect government benefits or the Medicare levy surcharge.
