Chattel mortgage, lease or novated? How to finance a work vehicle

Vehicle finance is where accounting and lending genuinely collide. Four products, similar monthly payments, and completely different tax outcomes. Pick the wrong one and you will not notice for a year — you will notice at BAS time, or when the FBT return arrives.

Chattel mortgage

You buy the vehicle. It is your asset from day one and appears on your balance sheet. The financier takes security over it.

GST: if you are registered for GST and report on a cash basis, you generally claim the full input tax credit on the purchase price in the quarter you buy — subject to the car limit cap and any private-use reduction. On accruals, the same. This is a genuine cash flow advantage: a meaningful GST refund in the first BAS after purchase.

Deductions: you claim depreciation on the vehicle, capped at the car limit for passenger cars, plus the interest component of each repayment. Not the principal.

Suits: businesses registered for GST that want to own the vehicle and can use a large early input tax credit. This is the most common choice for company and trust structures, and for sole traders with genuine business use.

Watch: the car limit caps both the GST you can claim and the depreciation you can claim on passenger vehicles. Commercial vehicles designed to carry more than one tonne or nine or more passengers are generally not subject to the car limit, which is a large part of why utes and vans are attractive — but the ATO looks at the vehicle's actual design, not its badge, and a dual-cab that carries under a tonne after accessories does not automatically qualify.

Finance lease

The financier owns the vehicle and leases it to you. There is a residual value at the end, and you generally have the option to pay it out and take ownership.

GST: claimed on each lease payment as you go, rather than up front.

Deductions: the lease payments are deductible to the extent of business use. No depreciation, because you do not own it.

Suits: businesses that want the deduction spread evenly and do not need the up-front GST refund, or that want the vehicle off the balance sheet for lending covenant reasons.

Watch: the residual value is set at the start and it is a real obligation. If the market value at the end is below the residual, that gap is yours.

Operating lease

A rental. The financier retains ownership and the residual risk, and you hand the vehicle back at the end.

Deductions: the whole payment is deductible for business use. Simple.

Suits: fleets, businesses that replace vehicles on a fixed cycle, and anyone who values predictable cost over ownership. Often bundled with maintenance and registration as a "fully maintained" product.

Watch: you build no equity, and excess kilometre and damage charges at handback are where the economics can turn. Read the return conditions before you sign, not at the end.

Novated lease

A three-way arrangement between you, your employer and a financier. Your employer makes the payments from your salary.

This is an employee product, not a business one. It is only available where there is an employer and an employee — which for an owner-operator means you need to actually be employed by your company, on payroll, and the company must be willing to enter the novation.

How it works: payments are deducted from your salary, usually as a combination of pre-tax and post-tax amounts. The pre-tax portion reduces your taxable income. The post-tax portion — the employee contribution method — is used to reduce the FBT liability to nil.

Watch: FBT is the whole game here. The statutory formula method applies a flat rate to the vehicle's base value, which means low-kilometre drivers are treated the same as high-kilometre drivers. The employee contribution method exists specifically to offset this, and the arithmetic has to be done properly or you end up with an unexpected FBT bill sitting with the employer — which, if you own the company, is you.

The electric vehicle exemption: eligible low-emissions vehicles below the luxury car tax threshold for fuel-efficient vehicles have attracted an FBT exemption, which has made novated leasing dramatically more attractive for EVs. The scope and end dates of this concession have been amended since it was introduced — in particular for plug-in hybrids — so confirm the current position for the specific vehicle and the specific date before relying on it. Reportable fringe benefits may still apply even where FBT is exempt, and that figure can affect things like Division 293, HELP repayments and family assistance.

The questions that actually decide it

Are you registered for GST, and would a large refund now be useful? If yes, chattel mortgage moves ahead.

Is the vehicle over or under the car limit? Above it, the capped GST and capped depreciation change the comparison, and a lease can look better.

Is it a passenger car or a genuine commercial vehicle? This changes both the car limit treatment and the FBT exposure.

Do you have a payroll and an employment relationship? Without one, novated leasing is not available at all.

Do you want the asset at the end? If you replace every three years regardless, ownership is a liability, not a benefit.

What does private use look like honestly? Every option except a purely business-use asset creates either an apportionment or an FBT question. Pretending a family car is 100% business is the most common and most findable error in this whole area — and a logbook is the only thing that settles it.

Do the comparison on total cost

Dealers and financiers compete on the monthly repayment, which is the least informative number available. Ask for:

• Total amount payable over the term
• The residual and who carries the risk on it
• All fees, including establishment, monthly account and early termination
• The effective annual rate, not a "comparison" figure invented for the brochure

Then run the after-tax cost through your actual structure. A monthly payment that is $80 higher can easily be the cheaper option once GST timing and deductions are counted — and the reverse is just as often true.
