You have found the prime mover you want. The deal stacks up on the numbers, the work is lined up, and now you need to decide how to fund it. A dealer or broker mentions a chattel mortgage and you nod along, but you want to actually understand what you are signing before you commit the truck to years of repayments.
A chattel mortgage is one of the most common ways Australian businesses fund a truck. The word chattel just means a moveable piece of property, in this case the truck, and mortgage means the lender takes security over it. This page explains how that structure works specifically when the asset is a truck, how repayments and balloons behave, where the GST questions sit, who it tends to suit, and how it differs from leasing.
Ownership and security structure
The defining feature of a chattel mortgage is that you own the truck from day one. The lender advances the funds, the truck is registered in your business name, and it goes on your books as your asset from the moment the deal settles. This is different from arrangements where the financier owns the asset and you pay to use it.
In exchange for lending against an asset you own outright, the lender registers a security interest over the truck. In practice that means the loan is secured by the truck itself, and the lender's interest is recorded on the Personal Property Securities Register. If the loan is not repaid, the lender has a clear path to recover the truck. Once the loan is paid out in full, that security interest is released and you hold the truck free and clear.
This structure is why a chattel mortgage often reads well to a lender. The debt is tied directly to a tangible, income-producing asset that holds resale value. A well-maintained truck with a known market can be recovered and sold, which lowers the lender's exposure. That security is part of why this product is so widely used for commercial vehicles.
Because the truck secures the loan, the asset itself matters to the assessment. A newer truck from a mainstream make with a deep resale market is straightforward. An older unit, a specialised body, or a privately sourced truck raises more questions, because the lender is thinking about what the asset would be worth if they ever had to sell it. If you are looking at an older or private-sale truck, the mechanics of valuation and register checks are worth understanding, and used truck finance covers those in detail.
How repayments and balloons work
A chattel mortgage is repaid over an agreed term in regular instalments. You and the lender settle on a term that suits the working life of the truck and the shape of your cash flow. A longer term lowers each repayment but means you pay for longer and hold the debt against an ageing asset. A shorter term clears the debt faster but demands more from monthly revenue.
Many operators put a deposit down, either as cash or by trading in an existing truck. A deposit reduces the amount financed, which lowers repayments, and it can make an application read more comfortably because you have skin in the deal. It is a lever, not a requirement, and how much makes sense depends on how you want to balance upfront cash against ongoing commitment.
The other major lever is the balloon, sometimes called a residual. This is a lump sum set aside to be paid at the end of the term rather than spread across the instalments. Parking a portion of the loan in a balloon lowers your regular repayments through the term. The trade-off is that the balloon is still owed when the term ends. At that point you generally pay it out, refinance it, or sell or trade the truck and clear it from the proceeds.
Balloons suit operators who want lower monthly outgoings and have a plan for the end of term, for example replacing the truck on a cycle and rolling into the next one. They are less comfortable if you have no clear exit, because a large sum falls due while the truck is older and worth less. Matching the balloon to the truck's likely resale value at term end is the sensible approach. Getting repayment shape right for how your revenue actually arrives is covered further in business truck loans.
GST timing questions
GST is where a chattel mortgage gets asked about most, and it is exactly the kind of question to route to a registered tax agent rather than guess at. Because you own the truck under this structure, the GST treatment on the purchase, and how and when input tax credits can be claimed, works differently from arrangements where the financier owns the asset.
How that plays out depends on your GST registration, whether you report on a cash or accruals basis, and how your accountant treats the acquisition. The timing of when you can claim can be a genuine cash flow consideration for a large truck purchase, so it is worth a conversation before you settle rather than after.
The same applies to depreciation and to how the interest portion of your repayments is treated at tax time. These turn on thresholds and rules that change and that depend on your circumstances, so the authority to rely on is a registered tax agent or the Australian Taxation Office. Do not size a purchase around a tax outcome you have assumed. Confirm it with someone who can look at your books.
Who a chattel mortgage suits
A chattel mortgage tends to suit a business that wants to own the truck outright, keep it on the balance sheet as an asset, and use it as a working part of the operation for the long haul. If you intend to run a truck hard for years and keep it well past any finance term, ownership from day one fits that intent.
An established operator with assets already on the books and a trading history often finds this product straightforward. The business can demonstrate cash flow, the truck adds to an existing fleet, and the security structure is clean. A newer ABN with work lined up can also use a chattel mortgage, though the lender will lean more on the strength of the asset, any deposit, and evidence that the contracts or work are real, because there is less trading history to read.
An owner operator buying a first truck is a common case too. Here the truck often is the business, so the lender looks closely at the asset, the deposit, and what the work looks like. A business replacing or upgrading gear is another natural fit, particularly where a trade-in funds part of the deal and the operator is on a known replacement cycle.
It suits you less well if you would rather not carry the asset and its risks on your books, or if you value handing the truck back at term end without dealing with resale. That is where leasing enters the picture.
How it differs from leasing
The cleanest way to understand a chattel mortgage is against a lease. Under a chattel mortgage you own the truck and the lender holds security. Under a lease the financier owns the truck and you pay for the right to use it over the term, with the asset sitting on their books rather than yours.
That single difference flows through to everything else. Ownership affects how the arrangement appears in your accounts, how the tax treatment works, and what happens at the end of the term. With a chattel mortgage the truck is yours to keep, sell or refinance once the loan clears. With a lease you typically face end-of-term choices set by the lease, which may include returning the truck or paying a residual to take it on.
Neither is better in the abstract. Ownership and the resale upside suit some operators; keeping the asset off the books and swapping trucks cleanly at term end suits others. The right choice depends on how long you plan to hold the truck, how you want your accounts to look, and your tax position, which again is a registered tax agent question.

Common questions
Is one lender's no the final word?
No. Lenders differ in how they read asset age, private sales, newer ABNs and the type of work you do. A structure that one lender declines can sit comfortably with another whose appetite matches your situation. This is a large part of why comparing offers is worth the effort rather than stopping at the first answer.
Can I use a chattel mortgage for a private-sale truck?
Yes, this is common. The lender will want the truck properly valued and will check the register for any existing security before settling. Private sales add a few steps compared with buying through a dealer, but they are routine for this product.
What do I need ready to apply?
Have your business identification, details of the truck, and a picture of your trading position ready. What the lender asks for shifts with how established the business is and how the truck is being sourced. A newer business or an older, privately sourced truck usually draws more questions, which is normal.
What to do next
If a chattel mortgage looks like the right shape for your truck, the useful next step is to see real numbers on your own deal rather than general ranges. You can request three free quotes at /quote/ and compare how different lenders would structure the term, deposit and balloon for your situation. Take the GST and tax questions to a registered tax agent in parallel, so the funding structure and the tax treatment are settled together before you commit.
