Novated Lease Residual Value Explained: The Balloon Payment Nobody Plans For

The residual value on a novated lease is the lump sum you still owe on the car when the lease ends. On a 5-year lease it is 28.13% of the amount financed, set as a minimum by the ATO, and you pay it with post-tax money plus GST. On a $60,000 electric car that is $16,878, or about $18,566 once GST is added. The novated lease residual value is the least understood number in the whole arrangement, and the one most likely to sting.

Plenty of drivers sign a lease for the tax savings, which are real. A $60,000 battery electric vehicle under the FBT exemption typically saves $10,000 to $18,000 over the term compared with buying from post-tax income. What far fewer people model is the day the lease ends: what they will owe, what the car will actually be worth, and what happens if those two numbers have drifted apart. For EVs, where used values have moved sharply, that gap deserves more attention than it gets.

Here is how the novated lease residual value works, why the percentages are fixed, and how to avoid being caught out.

How the ATO sets the minimum novated lease residual value

The ATO prescribes minimum residual percentages by lease term, and your provider cannot go below them. The figures come from ATO determination TD 93/142, which for cars works off an eight-year effective life:

Lease term	Minimum residual (% of amount financed)
1 year	65.63%
2 years	56.25%
3 years	46.88%
4 years	37.50%
5 years	28.13%

The logic is simple. A lease where you pay the car down to nothing is not really a lease, it is a loan wearing a lease’s paperwork. The minimum residual keeps genuine value in the vehicle at the end of the term, which is what makes the arrangement a lease in the tax office’s eyes and what unlocks the pre-tax treatment of your payments.

Two practical consequences follow. First, a short lease means a big balloon. Finance $60,000 over 3 years and the residual is $28,128; add GST at payout and you are writing a cheque for about $30,941. Stretch the same car over 5 years and the payout falls to $16,878, about $18,566 with GST. Second, there is almost no room to negotiate. Providers can set residuals above the minimum, and sometimes do for cars they expect to depreciate hard, but they cannot set them below it.

You pay the residual with post-tax money, and GST applies

The residual sits outside the salary sacrifice arrangement entirely. Your lease payments come out of pre-tax salary and enjoy GST savings along the way. The balloon does not. If you pay out the residual and keep the car, the ATO treats it as you buying the vehicle from the finance company, so GST applies to the residual payment and it comes from your own savings.

This is the detail that surprises people. Five years of payments that felt light because they came off your gross salary, then a five-figure bill that gets no tax help at all. Nothing about it is hidden, it is in every quote, but quotes are read for the weekly figure and not the last line.

Budget for it from day one. Dividing an $18,566 payout across a 60-month term is about $310 a month set aside, which is easier to swallow than finding the lump sum in year five.

The EV problem: when the car is worth less than the residual

An electric car can be worth less than its residual at lease end, and recent Australian data shows the risk is not theoretical. CarsGuide research tracking classified listings (published January 2025) found the average used Tesla Model 3 listing fell from $65,990 in January 2023 to $46,705 in December 2024, a 30% drop in two years. Used Tesla Model Y prices fell 36% over the same period, and the BYD Atto 3 and MG ZS EV each fell 29%.

Most of that damage came from new-car price cuts resetting the used market, not from the cars themselves failing. A new Tesla Model 3 starts at $54,900 before on-roads as of July 2026, well below what early adopters paid, and every cut to a new price drags used values down with it.

Run the numbers on a worked example. Say you financed $60,000 over 3 years in mid-2023. Your residual is $28,128 plus GST. If the market will only pay $26,000 for the car, selling it leaves you several thousand dollars short, and that shortfall is yours to cover with post-tax money. The lease’s tax savings usually still leave you in front overall, but the exit is nowhere near as clean as the brochure implied.

The reverse also happens. If your car is worth more than the residual, you sell it, clear the balloon and generally keep the surplus tax-free. Owners of models that held value well, like the Hyundai IONIQ 5 and Kia EV6, have come out ahead this way. The point is not that leasing an EV is a trap. It is that the residual turns you into a forced participant in the used EV market on a fixed date, so the trajectory of used values should influence which car and which term you pick.

Your four options at the end of a novated lease

When the lease ends you choose between four paths, and your provider will usually contact you about 90 days out.

Pay the residual and keep the car. One payment, post-tax, GST included, and the car is yours. This suits drivers whose car is worth comfortably more than the payout, or who simply want to keep a known-good vehicle. From that point you run it like any other owned car, and cheap home charging keeps running costs low.

Sell or trade in and walk away. The sale or trade-in proceeds clear the residual. Anything above it is generally yours tax-free; anything below it comes out of your pocket. Get an independent valuation before accepting a trade-in figure, because the dealer’s number and the private market can differ by thousands.

Refinance the residual on the same car. The residual rolls into a fresh lease term with its own, smaller residual at the end. This spreads the cost and keeps the pre-tax treatment of payments running, though you pay interest on the refinanced amount. Check the rate being applied; it is not always the rate you started on.

Start a new lease on a new car. The old car’s value clears the old residual, and you begin again with a new vehicle. Lease providers like this outcome for obvious reasons. It can still be the right call if the FBT exemption savings on a new EV outweigh the cost of switching, but do the maths rather than defaulting to it.

One more scenario worth planning for: leaving your job mid-lease. The novation sits with your employer, so if you change jobs the lease reverts to you personally. A new employer that supports novated leasing can pick it up, but between jobs you make the full payments from post-tax income, and an early termination means paying out the remaining balance plus the residual. If your employment is uncertain, that risk belongs in your decision alongside the tax savings.

Choosing a term that keeps the residual honest

Match the lease term to how long the car will hold value against its residual curve, not just to the repayment you can afford. A longer term gives the car more time to depreciate past the residual, which lowers your risk of finishing underwater. It also produces the smallest balloon: 28.13% at 5 years against 46.88% at 3.

Three checks before you sign:

1. Compare the residual against realistic resale projections, not against the new price. Look at what 3-to-5-year-old examples of the same model list for today and assume the curve continues.
2. Stay under the FBT cap. The exemption only applies to battery electric vehicles priced below the luxury car tax threshold for fuel-efficient vehicles, $91,661 for 2026-27 (ATO). Leases signed while the exemption applies keep it for their term.
3. Model the whole term, including the payout. Our novated lease calculator lets you compare the full cost of a lease against a loan or cash, with the residual included rather than ignored.

Around 157,000 EVs were sold in Australia in 2025 (Electric Vehicle Council, January 2026), and a large share went through novated leases. Most of those drivers will meet their residual between 2027 and 2030. The ones who planned for it from the first payslip deduction will find it a non-event.
