Luxury Car Tax in Australia 2026-27: Thresholds, Fuel-Efficient Rules, and Accountant Advice

The Luxury Car Tax (LCT) is one of Australia's more misunderstood taxes — and one that catches both businesses and individual buyers off guard. For the 2026–27 financial year, the ATO has updated the LCT thresholds, and a significant policy change that took effect on 1 July 2025 has fundamentally altered which vehicles qualify as "fuel-efficient" for the purposes of the higher threshold. Understanding these rules — and how they interact with GST, depreciation limits, and business deductions — is essential for any Australian business or individual purchasing a high-value vehicle. An experienced accountant can help you navigate the LCT framework and ensure your tax position is correctly managed.

What Is the Luxury Car Tax?

The Luxury Car Tax is a federal tax levied on the supply, importation, or sale of luxury cars in Australia. It applies at a rate of 33% on the portion of a vehicle's LCT value that exceeds the applicable threshold. The tax is typically remitted by the supplier — a car dealer, wholesaler, or importer — but the cost is invariably passed on to the buyer through the vehicle's purchase price.

LCT applies to new vehicles and to second-hand vehicles that were imported within the last two years. It does not apply to vehicles that are more than two years old at the time of importation, or to vehicles that are exempt from the tax — such as certain commercial vehicles, emergency vehicles, and vehicles modified for use by people with disabilities.

The LCT value of a vehicle is generally its GST-inclusive price, including dealer delivery charges, customs duty, and any accessories or modifications supplied at the time of sale. It does not include stamp duty, registration fees, transfer fees, or compulsory third-party (CTP) insurance premiums.

The 2026-27 LCT Thresholds

The ATO adjusts the LCT thresholds annually using an indexation factor based on the Consumer Price Index (CPI). For the 2026–27 financial year, the indexation factor is 1.003, resulting in the following thresholds.

• Fuel-efficient vehicles: $91,661
• All other vehicles: $80,809

These thresholds represent the GST-inclusive price above which LCT applies. For every dollar above the threshold, the effective additional cost to the buyer is approximately 30 cents — because the 33% LCT rate is applied to the excess amount.

It is important to note that the LCT threshold is distinct from the car limit used by the ATO for depreciation and GST input tax credit purposes. For 2026–27, the car limit is $69,883. This means that even if a vehicle is below the LCT threshold, the deductible cost for depreciation and GST credit purposes may still be capped at the car limit.

The New Fuel-Efficient Vehicle Definition

One of the most significant changes to the LCT framework in recent years took effect on 1 July 2025, when the Treasury Laws Amendment (Tax Incentives and Integrity) Act 2025 introduced a stricter definition of "fuel-efficient vehicle."

Under the previous rules, a vehicle qualified as fuel-efficient — and therefore eligible for the higher LCT threshold — if it had a combined fuel consumption rating of 7 litres per 100 kilometres or less. From 1 July 2025, this requirement was halved: a vehicle must now have a combined fuel consumption rating of 3.5 litres per 100 kilometres or less to qualify for the higher threshold.

This change has significant practical implications. Many hybrid vehicles that previously qualified for the higher $91,661 threshold may no longer do so under the new 3.5L/100km standard. Vehicles that consume between 3.5 and 7 litres per 100 kilometres are now subject to the lower $80,809 threshold — meaning LCT applies at a lower price point for these vehicles than it did before 1 July 2025.

Fully electric vehicles and plug-in hybrid vehicles with very low fuel consumption ratings are most likely to satisfy the new 3.5L/100km threshold. Buyers and businesses considering a vehicle purchase should verify the vehicle's official fuel consumption rating before assuming it qualifies for the higher threshold.

Key Considerations for Businesses and Buyers

The LCT framework interacts with several other tax rules in ways that require careful planning, particularly for businesses.

GST and LCT

LCT is separate from GST, but the two taxes interact. The LCT value is calculated on the GST-inclusive price of the vehicle. Businesses that are registered for GST can generally claim an input tax credit for the GST component of a vehicle purchase, but they cannot claim an input tax credit for the LCT component — LCT is not recoverable through the GST system.

The Car Limit and Depreciation

For business vehicles, the car limit ($69,883 for 2026–27) caps the amount that can be depreciated for tax purposes, regardless of the vehicle's actual purchase price. This means that even if a business purchases a vehicle for $120,000, the maximum depreciable cost is $69,883. The car limit also caps the GST input tax credit available on the purchase.

Instant Asset Write-Off and LCT Vehicles

The instant asset write-off provisions — which allow eligible businesses to immediately deduct the cost of certain assets — are subject to the car limit for passenger vehicles. This means that a business cannot use the instant asset write-off to deduct the full purchase price of a luxury car; the deduction is capped at the car limit. An accountant can help businesses understand how these rules apply to their specific vehicle purchases and business structure.

Novated Leases and LCT

Novated leases — a popular salary packaging arrangement — can involve vehicles that attract LCT. The LCT is generally included in the lease payments, and the tax treatment of novated leases for both the employer and employee requires careful consideration. An accountant or financial adviser can help structure a novated lease arrangement that is tax-effective within the applicable rules.

Common Mistakes and Red Flags

LCT compliance involves several common errors that can result in underpayments, penalties, or missed planning opportunities.

Assuming a Vehicle Is Fuel-Efficient Without Checking

The change in the fuel-efficient vehicle definition from 7L/100km to 3.5L/100km has caught many buyers and businesses off guard. Assuming a hybrid vehicle qualifies for the higher threshold without verifying its official fuel consumption rating can result in an unexpected LCT liability.

Confusing the LCT Threshold with the Car Limit

The LCT threshold and the car limit are two different figures with different purposes. Confusing them can lead to errors in both LCT calculations and depreciation claims. An accountant can clarify how each figure applies to a specific vehicle purchase.

Failing to Account for LCT in Business Budgets

Businesses that purchase vehicles above the LCT threshold without factoring in the LCT cost may find their vehicle acquisition budget significantly understated. At 33% on the excess, LCT can add tens of thousands of dollars to the cost of a high-value vehicle.

Incorrectly Claiming GST Credits on LCT

LCT is not recoverable through the GST system. Businesses that attempt to claim an input tax credit for the LCT component of a vehicle purchase are making an incorrect claim that may attract ATO scrutiny.

Australian Regulatory Context

The Luxury Car Tax is administered by the ATO under the A New Tax System (Luxury Car Tax) Act 1999. The ATO publishes the annual LCT thresholds and indexation factors on its website, and provides detailed guidance on the calculation of LCT value, exemptions, and the treatment of accessories and modifications.

The change to the fuel-efficient vehicle definition was legislated through the Treasury Laws Amendment (Tax Incentives and Integrity) Act 2025, which received Royal Assent and took effect from 1 July 2025. The policy intent was to align the higher LCT threshold more closely with genuinely low-emission vehicles, rather than the broader category of vehicles that previously qualified under the 7L/100km standard.

Businesses that supply, import, or sell luxury cars are required to register for LCT if they are registered for GST and their turnover from luxury car sales exceeds the registration threshold. LCT is reported and remitted through the business activity statement (BAS) process.

Questions to Ask Your Accountant

If you are considering purchasing a high-value vehicle — for personal or business use — these questions will help you have a productive conversation with your accountant.

1. Does this vehicle attract LCT, and if so, how much? — Ask your accountant to calculate the LCT based on the vehicle's LCT value and the applicable threshold.
2. Does the vehicle qualify as fuel-efficient under the new 3.5L/100km standard? — Verify the vehicle's official fuel consumption rating before assuming it qualifies for the higher threshold.
3. How does the car limit affect my depreciation and GST claims? — Understand the interaction between the LCT threshold, the car limit, and your business deductions.
4. Can I use the instant asset write-off for this vehicle? — The car limit caps the write-off for passenger vehicles, so the answer depends on the vehicle type and your business circumstances.
5. Is a novated lease or chattel mortgage more tax-effective for this purchase? — The optimal financing structure depends on your business structure, income, and the vehicle's intended use.
6. Are there any LCT exemptions that apply to my situation? — Certain commercial vehicles, emergency vehicles, and disability-modified vehicles may be exempt from LCT.
