Car finance through your business: the four ways to do it (and the tax bit)

Car finance through a business isn't one product, it's four, and the right one depends as much on your accountant's advice as on the finance itself. Get the structure right and you can claim GST, interest and depreciation. Get it wrong, or fail to log your business use, and you leave money on the table.

This guide explains the four structures, how each is treated for GST and tax, and which suits which kind of business, from a tradie's ute to a company fleet to an electric vehicle. The tax detail is general information, not advice, so treat the accountant caveat below as a real instruction, not boilerplate.

The four ways to finance a business vehicle

Chattel mortgage

A chattel mortgage is the workhorse of business vehicle finance and the most common choice for ABN holders. You own the vehicle from day one, and the lender takes a "mortgage" (a registered charge) over the "chattel" (the car) until you've repaid. Because you own it, if you're registered for GST you can generally claim the GST on the purchase price upfront, and claim depreciation and the interest portion of repayments over time.

Best for: ABN holders using the vehicle mainly for business who want ownership and the upfront GST benefit. Watch out: you carry the asset and its resale risk, and the depreciation and GST you can claim are capped for more expensive cars (see the EV note below).

Finance lease and operating lease

With a lease, the financier owns the vehicle and you pay to use it. Under a finance lease you typically have the option to buy it at the end for a residual (balloon) amount; under an operating lease you simply hand it back, more like a long-term rental. Lease payments are generally deductible to the extent of business use, and GST is usually claimable on the payments rather than upfront.

Best for: businesses that want lower upfront cost, predictable payments, and, with an operating lease, no resale risk. Watch out: you don't own the asset (finance lease until the residual is paid), and the total cost can exceed ownership over the life of the vehicle.

Novated lease

A novated lease is a three-way arrangement between an employee, their employer and a financier. The employee packages the car through their pre-tax salary, the employer makes the payments from that salary, and the financier provides the vehicle. It's an employee benefit rather than a business-asset purchase, and it brings Fringe Benefits Tax (FBT) into play.

Best for: employers offering vehicles as part of salary packaging, and employees who want to fund a car pre-tax. Watch out: FBT and the mechanics are genuinely complex, this is the structure most in need of proper advice before you commit.

Business car loan

A standard business car loan is a secured loan used to buy the vehicle. You own the car, the loan is secured against it, and you can generally claim depreciation and the interest portion. It's simpler and more consumer-like than a chattel mortgage, and often the straightforward choice when the vehicle isn't used heavily for business.

Best for: simplicity, and vehicles with a lower business-use percentage. Watch out: it may not offer the same upfront GST treatment as a chattel mortgage, which is why business-heavy users often prefer the latter.

The tax treatment, side by side

This table is general information only, not tax or financial advice. Funding Loop arranges finance; we are not accountants or registered tax agents. Tax outcomes depend on your GST registration, your accounting method, the vehicle, and your business-use percentage, so confirm your specific position with your accountant before choosing a structure.

Five real scenarios

The tradie's ute, 100% business use. A plumber's ute used only for work. A chattel mortgage is the classic fit: full ownership, upfront GST claim, and depreciation and interest deductible against a 100% business-use vehicle.

The sales rep, 60/40. A car used 60% for work, 40% personally. The structure still works, but deductions are limited to the 60% business portion, so the logbook is what protects the claim. This is exactly the case where sloppy record-keeping costs money.

The company fleet of three. A business adding three vehicles at once. Chattel mortgages or a lease across the fleet, chosen for cash-flow and balance-sheet reasons, and worth structuring with the accountant given the scale.

The sole trader, low doc. A self-employed sole trader without full financials prepared. Low-doc vehicle finance assessed on the asset and basic details is often available, which is why sole trader and self-employed car finance is accessible even without a full financial workup.

Financing an EV or Tesla through a business

Electric vehicles have their own wrinkles. The finance structures are identical, but the tax treatment can differ: there have been FBT concessions for eligible EVs, which can make a novated lease particularly attractive for an electric car. Set against that, the ATO applies a car cost limit that caps the depreciation and GST you can claim on more expensive vehicles, and many EVs sit near or above it. The EV rules change more often than the rest, so this is another spot where current, personalised advice matters.

What it actually costs

The cost of business car finance comes down to the interest rate, the term, any balloon or residual, and fees. A balloon payment (a lump sum owed at the end) lowers your regular repayments but leaves a large amount to refinance or pay out later, so a low monthly figure can hide a big final one.

As an illustration, a $50,000 vehicle financed over five years will have a monthly repayment driven by the rate and any residual. Set a $15,000 balloon and the monthly payments drop noticeably, but you owe that $15,000 at the end. Compare offers on the total cost over the full term, including the balloon, not just the monthly figure.

What you need to qualify

Vehicle finance is usually more accessible than an unsecured loan, because the car secures the deal. For most lenders you'll need an active ABN and some trading history, though low-doc options exist for newer businesses and sole traders precisely because the asset carries the risk. Used vehicles can generally be financed too, within age limits at the end of the term. The general requirements are here.

Common questions

Is it better to buy a car through my business or personally?

If the vehicle is used substantially for business, buying it through the business usually allows you to claim GST, depreciation and interest on the business-use portion, which personal ownership doesn't. If business use is minimal, the benefits shrink and personal ownership may be simpler. Your business-use percentage and your accountant's advice decide it.

Can I claim the GST on a car bought through the business?

Generally, yes, if you're registered for GST and use the vehicle for business, most often upfront under a chattel mortgage, or on the payments under a lease. The claim is limited to your business-use percentage, and the ATO's car cost limit caps the GST claimable on more expensive vehicles. Confirm the specifics with your accountant.

What's the difference between a chattel mortgage and a car loan?

Both leave you owning the vehicle with the finance secured against it, but a chattel mortgage is a commercial product designed for business use, typically allowing an upfront GST claim and business deductions. A standard car loan is more consumer-oriented and may not offer the same GST treatment. Business-heavy users usually prefer a chattel mortgage for that reason.

Can a new ABN holder get car finance?

Often, yes. Because the vehicle secures the loan, low-doc and new-ABN vehicle finance is more accessible than an unsecured loan would be. Newer businesses may face a slightly higher rate or a deposit, but a lack of long trading history is far less of a barrier when the asset itself is the security.

Can I finance a used car through my business?

Yes. Used vehicles can be financed through the same structures, subject to lender limits on the vehicle's age at the start and end of the term. Older vehicles may attract a shorter term or a higher rate, but financing a used car through the business is common and the tax treatment follows the same principles.
