Salary Sacrifice Second Hand Car and Your Take-Home Pay
Salary sacrificing a second-hand car is a popular way to reduce your taxable income while getting a vehicle for work or personal use. Under a salary sacrifice arrangement, your employer takes the car payments from your pre-tax salary, lowering the amount of income tax you pay. But how does this affect your take-home pay compared to the national full-time average? Let’s break it down using the latest figures from the ABS, Fair Work, and the ATO.
The National Full-Time Average as a Reference
The national full-time adult ordinary-time average is $2,083.70 per week, or about $108,352 per year, according to the ABS Average Weekly Earnings for May 2026 (multiplied by 52). This is the benchmark used on this site. The full-time median is lower at about $90,532, and the all-employees median is about $74,100 (ABS Employee Earnings, August 2025). Men’s full-time average is about $113,412, women’s about $100,594. These figures help you see where your salary sits on the line.
When you salary sacrifice a second-hand car, your taxable income drops. For example, if you earn the average of $108,352 and sacrifice $10,000 for a car, your taxable income becomes $98,352. Using the 2026–27 resident tax rates (nil to $18,200; 15% to $45,000; 30% to $135,000; 37% to $190,000; 45% above that, plus 2% Medicare levy), you save tax at your marginal rate of 30% on that $10,000, meaning you keep about $7,000 more after tax than if you paid for the car with after-tax dollars. However, your take-home pay (after tax and the sacrifice) will be lower than someone earning the same gross salary without a sacrifice.
How Salary Sacrifice Works for a Second-Hand Car
Salary sacrifice for a car is typically done through a novated lease or an employer-provided vehicle. The ATO treats the car as a fringe benefit, and your employer may have to pay fringe benefits tax (FBT) if the car is available for private use. However, there are exemptions for certain vehicles, such as those that are primarily used for work. The ATO’s rules on FBT are complex, but for a second-hand car, the same principles apply as for a new car. The car must be used for work purposes, and the sacrifice amount must be agreed with your employer.
One key point: the car’s value affects the FBT calculation. The ATO uses a statutory formula based on the car’s base value (usually its cost, including GST). For a second-hand car, the base value is the market value at the time it’s first provided as a fringe benefit. If the car is older, the base value may be lower, which can reduce FBT. But you still need to consider the impact on your take-home pay.
Take-Home Pay Sketch for an Average Earner
Let’s sketch a resident earning the national full-time average of $108,352. Without salary sacrifice, their tax (including Medicare levy) on that income is roughly: $0 on first $18,200, then 15% on $26,800 ($4,020), then 30% on $63,352 ($19,005.60), total tax $23,025.60, plus Medicare $2,167.04, leaving take-home about $83,159.36 per year, or $1,599.22 per week on a 38-hour week.
Now, if they salary sacrifice $10,000 for a second-hand car, their taxable income is $98,352. Tax: $0 on $18,200, 15% on $26,800 ($4,020), 30% on $53,352 ($16,005.60), total tax $20,025.60, Medicare $1,967.04, take-home $76,359.36. But they also have the car payments covered by the sacrifice, so their disposable income after tax and car is $76,359.36 (since the car is paid pre-tax). Compared to the non-sacrifice scenario where they would have paid for the car with after-tax money, they save about $2,800 in tax. However, their take-home cash is lower because the sacrifice reduces their gross pay.
How This Compares to State Averages and Minimum Wage
The national average masks state differences. For instance, the ACT full-time average is about $119,090, while Tasmania is about $96,008. If you live in a state with a higher average, your salary sacrifice may have a larger tax benefit because you’re in a higher tax bracket. Conversely, if your salary is near the national minimum wage of $52,255 per year (from 1 July 2026, based on $26.44 per hour for 38 hours), salary sacrificing a car may not be worthwhile because you’re already in the 15% bracket and the sacrifice could push you below award rates.
Fair Work sets award minimums, which rose by 4.75% from 1 July 2026. If your salary after sacrifice falls below the award rate for your classification, your employer may not be able to make the arrangement. Always check your award or agreement.
Using This Site to See Where You Stand
You can place a salary on the line to see how your pay compares to the national full-time average, medians, and minimum wage. The tool shows your weekly and hourly amounts on a 38-hour week, plus the distance from the average. If you’re considering salary sacrifice, enter your base salary before the sacrifice to see where you sit, then subtract the sacrifice amount to see the effect on your taxable income.

Key Considerations
- FBT: Your employer may pass on the FBT cost, which could reduce your savings. Some cars (e.g., electric vehicles) have FBT exemptions.
- Super: Salary sacrifice reduces your employer’s super guarantee contributions (currently 11.5% of ordinary time earnings). Check if your employer calculates super on your pre-sacrifice salary.
- Leave: Your base salary for leave entitlements may be affected. Check your award.
- Residual value: At the end of a novated lease, you may have to pay a residual amount. Factor that into your budget.
In summary, salary sacrificing a second-hand car can be a tax-effective way to get a vehicle, but it’s important to understand how it affects your take-home pay relative to the national average. Use the tools on this site to compare your situation.
