Electric Car Salary Sacrifice: How State and Industry Earnings Affect Your Benefit

What Is Electric Car Salary Sacrifice?

Electric car salary sacrifice is an arrangement where your employer allows you to pay for an electric vehicle (including running costs) from your pre-tax salary. This reduces your taxable income, and because eligible electric cars are exempt from fringe benefits tax (FBT) under Australian law, the tax savings can be significant. The Salary Index measures where your gross ordinary-time earnings sit against the national line of 100, which is $108,352 per year (based on ABS Average Weekly Earnings, May 2026). Salary sacrifice does not change that gross figure, but it affects your take-home pay and tax position.

How the Salary Index Relates to Salary Sacrifice

The salary index is a benchmark for full-time adult ordinary-time earnings before any deductions or sacrifices. If you earn exactly the national line, your index is 100. If you earn more, your index rises; if less, it falls. For example, a worker on the national minimum wage of $52,255 per year has an index of 48.2. When you enter an electric car salary sacrifice arrangement, your gross pay remains the same for index purposes, but your taxable income drops by the sacrificed amount. This means your index stays the same, but your tax bill shrinks. The benefit is larger for workers on higher marginal tax rates, which is where state and industry differences come into play.

State Differences in Earnings and the Impact on Salary Sacrifice

Earnings vary significantly across Australian states and territories, as shown in the states data. The highest average full-time ordinary-time earnings are in the ACT (index 109.9, annualised $119,090) and Western Australia (index 106.9, $115,825). A worker in the ACT on that average would have a marginal tax rate of 37% (plus 2% Medicare levy) for income above $135,000, but since the average is below that threshold, the marginal rate is 30% for most of their income. Still, the tax saved from salary sacrifice is higher than for a worker in Tasmania (index 88.6, $96,008), where the marginal rate is also 30% but the total income is lower, so the absolute saving is less. The FBT exemption for electric cars means you avoid the 47% FBT rate that would apply to a conventional car, making the arrangement especially valuable in high-earning states. However, the exact benefit depends on your personal pay, not just the state average.

Industry Differences: Where the Benefit Shifts

Industry also plays a role. The industries data shows Mining has an index of 154.7 (annualised $167,600), while Retail trade is at 75.9 ($82,200) and Accommodation and food services at 72.5 ($78,600). A mining worker on that average would be in the 37% tax bracket (plus Medicare), so every dollar sacrificed saves 39 cents in tax. A retail worker on the industry average would be in the 30% bracket, saving 32 cents per dollar. The difference is meaningful, but both benefit from the FBT exemption. For workers on award rates or near the minimum wage, the tax saving is smaller, and salary sacrifice may not be worthwhile unless the car's cost is low. The how the index works page explains that index figures are gross benchmarks, not a quote for a person. So while industry averages give a guide, your individual pay determines the real outcome.

Key Considerations for Your Pay

When considering electric car salary sacrifice, remember that your salary index is based on your gross ordinary-time earnings, not your sacrificed amount. The arrangement does not affect your super guarantee (12% from 1 July 2026) because super is calculated on your ordinary-time earnings before sacrifice. However, salary sacrifice can reduce your taxable income, potentially lowering your Medicare levy surcharge if applicable. The national minimum wage and award minima are not changed by salary sacrifice, but your employer must agree to the arrangement. For more on how pay guides and awards interact with salary packaging, see pay guides.

In summary, electric car salary sacrifice is a tax-effective way to drive an electric vehicle, but its value depends on your gross earnings, which vary by state and industry. Use the salary index to understand where your pay sits, and talk to your employer or a tax professional to model your specific situation. The figures in this article are based on national benchmarks; your actual index may differ.
