Chattel mortgage and business car finance basics

Published 30 July 2026. General information only, not personal or tax advice. Talk to your accountant about your own circumstances.

What is a chattel mortgage?

Despite the old fashioned name, a chattel mortgage is a straightforward business car loan. The "chattel" is the vehicle, and the "mortgage" is the lender's security over it. The lender advances the funds, you buy the vehicle and own it from day one, and the lender registers its interest over the car until the loan is repaid. Then the security is released and the car is yours outright.

That ownership point is the key difference from a lease. With a lease, the financier owns the vehicle and you pay to use it. With a chattel mortgage, the asset sits on your books from the start, which flows through to how the tax treatment works.

Who can use one?

A chattel mortgage is for business use. That includes companies and trusts, but also partnerships and sole traders, you don't need to be a big operation. The usual requirements are an ABN, and that the vehicle is used predominantly for business purposes. Tradies financing a ute, couriers financing a van, an owner operator adding a vehicle to a small fleet: these are the classic cases. Plenty of everyday self employed people qualify without realising it.

Why businesses choose a chattel mortgage

Potential tax treatment

Because your business owns the vehicle, it may be able to claim depreciation on the vehicle and the interest on the loan, for the business use portion. If your business is registered for GST, it may also be able to claim a credit for the GST in the vehicle's price, typically on the Business Activity Statement after purchase, depending on your accounting method.

Two honest caveats. First, the rules around depreciation, GST credits and any instant asset write off change over time and depend on your situation, so confirm the current position with your accountant before you rely on it. Second, the tax tail shouldn't wag the dog: the vehicle and the loan need to make commercial sense on their own.

Cash flow control

Chattel mortgages usually run over one to seven years with fixed repayments, so the cost is predictable. You can often finance the full purchase price, or put in a deposit or trade in to shrink the loan.

Balloon options

Many chattel mortgages let you set a balloon, a lump sum left to the end of the term. A balloon lowers each repayment along the way, which helps cash flow, but the lump sum is still owed at the end. Common ways to handle it: pay it out, refinance it, or sell or trade the vehicle and clear it. Decide your exit plan when you set the balloon, not when it lands. If you end up refinancing one, the mechanics are similar to what we describe in how to refinance a car loan.

What about low doc options?

Newer businesses and sole traders don't always have two neat years of financials to show. Some lenders on our panel offer low doc options, where the application leans on things like your ABN and GST registration history, bank statements and a clean credit record instead of full financial statements. Criteria vary a lot between lenders, which is exactly the sort of matching a broker does. Our business and equipment finance page covers what we arrange, and it extends beyond cars to utes, vans, trucks and yellow goods.

Chattel mortgage vs a consumer car loan

If the vehicle is mostly for personal use, a chattel mortgage isn't the right structure, that's what a standard car loan is for, and consumer credit protections apply to it. The rough rule: predominantly business use points to a chattel mortgage, predominantly personal use points to a consumer loan. If your use is genuinely mixed, this is a conversation to have with your accountant and your broker before you apply, because the structure affects tax, protections and which lenders are available.

What you'll need to apply

• Your ABN details, and GST registration if you have it
• Photo ID for the directors, partners or sole trader
• Financials or bank statements, or a low doc alternative where available
• The vehicle details and the invoice or contract, dealer and private sales can both work
• An idea of the term, deposit and any balloon you want

Before signing, run the numbers on total cost over the term, including the balloon, our repayment calculator is a reasonable place to start, and ask the same questions you'd ask on any loan: total repayable, fees, early payout costs, and exactly which lender it's with.

The bottom line

A chattel mortgage is simply the business version of a car loan: you own the vehicle, the lender holds security, and the structure opens up tax treatment a personal loan can't. Get your accountant's advice on the tax side, decide your balloon exit before you set one, and let a broker match your business, and its paperwork reality, to a lender that suits it.
