On 24 April 2026, if you are in the market for a high-value vehicle in Australia, knowing your luxury car tax liability before purchase is essential. The LCT calculator helps you estimate the exact cost impact based on your vehicle price and type.
How to Use the Luxury Car Tax Calculator
Using the luxury car tax calculator is straightforward. Enter two pieces of information to get an instant LCT estimate:
- Vehicle price including GST: The total purchase price as displayed by the dealer, including the 10% GST
- Vehicle type: Select whether it is a petrol or diesel vehicle, or an electric vehicle
The calculator applies the current 33% LCT rate to the amount above the applicable threshold.
2026 Luxury Car Tax Thresholds
The calculator uses these current thresholds:
- Fuel vehicles: AUD 89,332 (petrol, diesel, hybrid)
- Electric vehicles: AUD 91,316 (higher threshold encourages EV adoption)
Example Calculations
Using the LCT formula (Price - Threshold) x 33%:
- AUD 100,000 petrol: ($100,000 - $89,332) x 33% = $3,520.44
- AUD 120,000 petrol: ($120,000 - $89,332) x 33% = $10,120.44
- AUD 95,000 electric: ($95,000 - $91,316) x 33% = $1,215.72
- AUD 150,000 petrol: ($150,000 - $89,332) x 33% = $20,020.44
Additional Costs Beyond LCT
The luxury car tax is only one component of the total tax burden on high-value vehicles. Remember to budget for:
- State stamp duty: Varies by state from 1.5% to 5% of vehicle value
- Registration fees: Annual cost, higher for luxury vehicles in some states
- CTP insurance: Compulsory third party insurance, mandatory in all states
- Transfer fees: One-time cost when changing ownership
Summary
The luxury car tax calculator uses the current ATO thresholds and 33% LCT rate to provide instant estimates. For fuel vehicles the threshold is AUD 89,332, while EVs enjoy a higher AUD 91,316 threshold. Always budget for stamp duty and registration on top of the LCT estimate.
