Hold onto your wallets, because the cost of going green just got a lot more expensive than anyone expected. A massive miscalculation in the cost of tax breaks for electric cars has been exposed, revealing a staggering $1.35 billion in lost tax revenue this financial year alone—that's 18 times higher than the original forecast! But here's where it gets controversial: while these incentives were meant to drive eco-friendly adoption, they might be benefiting the wrong crowd. Let’s dive into the details.
New data has shed light on the Federal Government’s gross underestimation of the cost of a popular tax break for electric and plug-in hybrid cars in novated leases. This incentive, which allows employees to pay for vehicles from their pre-tax income, has been a hit, with over 100,000 takers in just three years. However, Treasury figures now estimate the lost tax revenue from the Fringe Benefits Tax (FBT) exemption for electric vehicles at a jaw-dropping $1.35 billion for the 2025-26 financial year. Compare that to the original forecast of $70 million when the policy was proposed ahead of the 2022 Federal Election, and you’ve got a massive blowout.
But that’s not all—the latest government estimates have also dramatically increased cost projections for current and prior years. For instance, data from late 2024 predicted lost tax revenue of $60 million for 2022-23, rising to $335 million by 2025-26. Fast forward to today, and those figures have skyrocketed to $290 million, $710 million, $1 billion, and $1.35 billion, respectively. This means the total loss in tax revenue from the FBT exemption between 2022 and 2028 is now projected at $7.3 billion—far exceeding the $1.795 billion estimated just months ago.
And this is the part most people miss: Treasury admits its projections are only “medium [to] low” in accuracy. The government claims these estimates are updated annually to reflect the latest data, but the sheer scale of the increase raises questions. For example, the 2024-25 Tax Expenditures and Insights Statement, released amid a surge in plug-in hybrid sales, actually decreased forecasts due to “updated data on vehicle sales and prices.” Yet, just months later, we’re seeing a 300-390% increase in cost projections. What changed?
Here’s where it gets even more interesting: while the policy has been popular in outer suburbs like Baulkham Hills, Werribee, and Springfield, research suggests it might not be benefiting the average Aussie. According to the Electric Vehicle Council and leasing lobby groups, nearly half of electric-car novated-lease customers earn over $150,000 annually. This raises a thought-provoking question: Are these tax breaks truly promoting widespread eco-friendly adoption, or are they subsidizing luxury purchases for high-earners?
The FBT exemption was introduced alongside legislation exempting electric vehicles under the Luxury Car Tax (LCT) threshold from a 5% import tariff. However, the government’s Productivity Commission has recommended scrapping the FBT exemption, arguing it costs taxpayers between $1,000 and $20,000 per tonne of avoided CO2-e. With a statutory review of these exemptions now underway, Treasurer Jim Chalmers acknowledges their success but questions their long-term viability.
So, here’s the big question for you: Should these tax breaks continue, or is it time to rethink how we incentivize electric vehicle adoption? Let us know your thoughts in the comments—this is one debate that’s just getting started!
