What a Car Allowance Salary Package Means for Your Pay Index
Understand how a car allowance salary package affects your position on the Australian salary index, with examples and key considerations for tax and super.
The index for a car allowance salary package depends on the total gross earnings; without a specific figure, it is uncertain where it sits relative to the national line of 100.
What Is a Car Allowance Salary Package?
A car allowance salary package is a compensation arrangement where an employer provides a regular cash payment—typically monthly or fortnightly—to cover the costs of using your personal vehicle for work purposes. This is different from a company car or a novated lease. The allowance is added to your base salary and forms part of your total gross earnings. Employers often use car allowances to simplify vehicle-related expenses without managing a fleet or FBT obligations.
For the purpose of the Salary Index, the key figure is your total gross ordinary-time earnings. If your car allowance is paid as part of your regular salary (not reimbursed on an expense-by-expense basis), it counts toward that total. The index compares your yearly gross earnings to the national line of 100, which represents full-time adult ordinary-time earnings of $108,352 per year (based on ABS Average Weekly Earnings, May 2026).
How a Car Allowance Affects Your Index Position
To see where a car allowance salary package sits on the index, you add the allowance to your base salary and divide by the national line. For example, if your base salary is $80,000 and your car allowance is $15,000, your total gross ordinary-time earnings are $95,000. The index is $95,000 ÷ $108,352 × 100 ≈ 87.7. That is below the national average, but above the national minimum wage index of 48.2 ($52,255 per year).
If your base salary is $110,000 and your car allowance is $10,000, your total is $120,000, giving an index of 110.8—above the national line. The exact figure depends on your specific package. Without a precise median for car allowance amounts, it is uncertain where a typical car allowance salary package sits. However, you can calculate your own index using the formula.
State and Industry Variations
The national line is an average, but pay levels differ across states and industries. For instance, the states page shows that Western Australia has an index of 106.9 ($115,825 annualised) and the Australian Capital Territory is 109.9 ($119,090), while Tasmania is 88.6 ($96,008). If you work in a high-index state, your car allowance salary package may still be below the state average unless your total earnings are proportionally higher.
Similarly, industries vary widely. Mining has an index of 154.7, while retail trade is 75.9 and accommodation and food services is 72.5. A car allowance is more common in roles that require travel, such as sales, field service, or construction. In professional, scientific and technical services (index 114.7), car allowances are often part of executive or client-facing roles. In lower-index industries, a car allowance might push your total closer to the national average.
Tax and Super Considerations
A car allowance is treated as ordinary income for tax purposes. It is included in your assessable income and taxed at your marginal rate. Unlike a car benefit provided by your employer, a cash allowance is not subject to fringe benefits tax (FBT). This means you are responsible for all vehicle expenses—fuel, maintenance, insurance, and depreciation—but you also have the flexibility to claim work-related car expenses as deductions if you keep a logbook or use the cents-per-kilometre method.
For superannuation, the car allowance is generally part of your ordinary time earnings. From 1 July 2026, the super guarantee rate is 12% on earnings up to $270,830. So if your car allowance increases your gross earnings, your employer must contribute 12% of that amount into your super fund. This is a significant benefit over time, as it boosts your retirement savings.
Comparing to Award and Minimum Wage Floors
The national minimum wage from 1 July 2026 is $26.44 per hour, $1,004.90 per week, annualised $52,255 (index 48.2). Entry-level award floors start at $25.74 per hour. Most car allowance salary packages are well above these floors, but the allowance itself is not subject to award minimums unless your award specifically sets a car allowance rate. Many modern awards include a vehicle allowance clause, often expressed as a cents-per-kilometre rate or a fixed amount per week. If you are covered by an award, check the pay guides for your industry.
How to Use the Salary Index for Your Package
The how the index works page explains that the index is a simple ratio: your yearly gross ordinary-time earnings divided by the national line ($108,352) times 100. To apply it to a car allowance salary package:
- Add your base salary and your annual car allowance.
- Divide that total by $108,352.
- Multiply by 100.
The result tells you how your package compares to the national average. For example, a total of $90,000 gives an index of 83.1; $130,000 gives 120.0. You can also compare to your state or industry index using the states and industries pages.
Common Questions About Car Allowance Packages
Many people wonder whether a car allowance is worth more than a company car. The answer depends on your personal tax situation, vehicle costs, and whether you can claim deductions. A car allowance gives you cash and control, but you bear the risk of higher running costs. A company car may include fuel and maintenance but can trigger FBT for private use. The salary index treats both as part of your remuneration, but the cash allowance directly increases your gross earnings figure.
Another question is whether a car allowance is negotiable. Yes, it is often a flexible component of a salary package. Employers may offer a higher allowance instead of a base salary increase, or vice versa. When negotiating, consider the impact on your index position and super contributions.
Final Thoughts
A car allowance salary package can move your pay index up or down depending on the total amount. While the national line is a useful benchmark, your actual position depends on your base salary, the allowance, and your state or industry context. Use the Salary Index tools to calculate your own figure and compare it to the averages. Remember that the index is a gross ordinary-time measure—your take-home pay will be lower after tax and Medicare levy.

Questions people ask
Is a car allowance included in the salary index calculation?
Yes, if the car allowance is part of your gross ordinary-time earnings. The salary index is based on yearly gross ordinary-time earnings divided by the national line ($108,352) times 100. A car allowance that is paid regularly as part of your salary package is generally included in that gross figure, so it will affect your index position.
Does a car allowance affect superannuation?
Yes, car allowances are generally considered ordinary time earnings for superannuation purposes. Under the Super Guarantee (Administration) Act 1992, ordinary time earnings include allowances that are paid for the performance of work. From 1 July 2026, the super guarantee rate is 12% on earnings up to the maximum contribution base of $270,830. So a car allowance will increase the base on which your employer calculates super contributions.
How is a car allowance taxed?
A car allowance is treated as ordinary income and is subject to PAYG withholding. It is included in your assessable income for the year and taxed at your marginal rate. For the 2026–27 income year, resident tax rates (excluding Medicare) are: nil up to $18,200; 15% from $18,201 to $45,000; 30% from $45,001 to $135,000; 37% from $135,001 to $190,000; and 45% above $190,000. The Medicare levy of 2% also applies. Unlike a car benefit provided by an employer, a car allowance is not subject to fringe benefits tax (FBT) because it is cash paid directly to you.
