Tesla Model S salary sacrifice: how it affects your gross pay, super and tax

What does 'Tesla Model S salary sacrifice' mean?

Salary sacrifice is an arrangement where you agree to give up part of your pre-tax salary in exchange for a benefit provided by your employer. In Australia, this is commonly used for cars, including electric vehicles like the Tesla Model S. The benefit is often provided under a novated lease, and the payments come out of your gross pay before tax, reducing your taxable income.

When you salary sacrifice a Tesla Model S, you are effectively using pre-tax dollars to cover the car's lease costs, running expenses, and any fringe benefits tax (FBT) that may apply. The key question for most people is: how does this affect my take-home pay, super, and overall financial position? This guide explains where such an arrangement sits against the national salary index and the rules set by the Fair Work Ombudsman, Australian Bureau of Statistics, and the ATO.

How the salary index relates to your pay

The Salary Index measures your yearly gross ordinary-time earnings against the national line, where 100 equals full-time adult ordinary-time earnings of $108,352 per year (based on ABS Average Weekly Earnings, May 2026). If you earn $120,000, your index is about 110.8. If you earn $80,000, your index is about 73.8.

For a Tesla Model S salary sacrifice, your gross pay before the sacrifice is the starting point. The sacrifice reduces your taxable income, but the index itself is based on your gross ordinary-time earnings, not your sacrificed amount. So if you earn $150,000 (index 138.5) and sacrifice $30,000 for the car, your taxable income drops to $120,000, but your index remains 138.5 for benchmarking purposes.

Gross pay and the impact of salary sacrifice

Salary sacrifice lowers your gross taxable income, which can move you into a lower tax bracket. For the 2026–27 financial year, resident tax rates (excluding Medicare) are:

• $0–$18,200: nil
• $18,201–$45,000: 15%
• $45,001–$135,000: 30%
• $135,001–$190,000: 37%
• Above $190,000: 45%

Plus a 2% Medicare levy. By reducing your taxable income, you pay less tax and Medicare levy. However, your employer's superannuation guarantee (12% from 1 July 2026) is calculated on your reduced salary, so your super contributions may be lower unless you make additional voluntary contributions.

Example: hypothetical scenario

Suppose you earn $130,000 a year (index 120.0). You salary sacrifice $25,000 for a Tesla Model S lease. Your taxable income becomes $105,000. You save tax on the $25,000 at your marginal rate of 30% plus 2% Medicare, a saving of $8,000. But your super guarantee drops from $15,600 (12% of $130,000) to $12,600 (12% of $105,000), a reduction of $3,000. Your net benefit is $5,000, but you also have the car costs covered. This is a simplified illustration; actual outcomes depend on FBT, the car's cost, and your employer's policy.

Superannuation considerations

Because salary sacrifice reduces the base for the super guarantee, you may want to consider salary sacrificing additional amounts into super to maintain your retirement savings. The super guarantee maximum contribution base is $270,830 for 2026–27, so high earners are not affected beyond that. You can also use the pay guides to check award rates if you are covered by a modern award, though salary sacrifice is typically a workplace agreement matter.

FBT and the Tesla Model S

The Tesla Model S is a luxury electric vehicle with a high purchase price. From 1 July 2025, the Australian government exempted certain electric cars from FBT, but only if the car's first retail price is below the luxury car tax threshold for fuel-efficient vehicles. For 2025–26 that threshold was $89,332, and the Tesla Model S starts well above that. Therefore, FBT is likely to apply. The FBT rate is 47% (including the Medicare levy surcharge component), and the taxable value of the car is calculated using the statutory formula or operating cost method. This can significantly affect the cost of salary sacrifice.

Your employer may pass the FBT cost on to you, either through additional salary sacrifice deductions or as a reportable fringe benefit on your payment summary. This can affect your entitlement to certain government benefits and the Medicare levy surcharge.

Where does this sit on the salary index?

Because the Tesla Model S is an expensive car, salary sacrificing it usually requires a gross salary well above the national line. The states page shows that average earnings vary: for example, the ACT has an index of 109.9 ($119,090), while Tasmania is 88.6 ($96,008). If you live in a higher-earning state like WA (index 106.9) or the ACT, you are more likely to have the income to support such an arrangement.

Similarly, industries with higher indices, such as Mining (154.7) or Professional, scientific and technical (114.7), are more likely to have employees who can afford a Tesla Model S salary sacrifice. In contrast, Retail trade (75.9) or Accommodation and food services (72.5) are less likely.

Tax and take-home pay

Your take-home pay after salary sacrifice depends on your marginal tax rate, the amount sacrificed, and any FBT. The ATO treats the sacrificed amount as a reduction in your gross salary, so you only pay tax on the lower figure. However, the FBT component (if any) is not deductible to you, but it is a cost to your employer that may be passed on.

For a resident taxpayer claiming the tax-free threshold, the Medicare levy is 2% of taxable income. The figures in this guide ignore HELP repayments, the Medicare levy reduction, and the Medicare levy surcharge, which could apply if you have private health insurance or not.

Key takeaways

• Salary sacrificing a Tesla Model S reduces your taxable income but may lower your super guarantee contributions.
• The Tesla Model S is unlikely to qualify for the FBT exemption on electric cars, so FBT may apply.
• Your gross salary needs to be well above the national line (index 100) to make the arrangement worthwhile.
• Always check with your employer and a tax professional, as individual circumstances vary.
