What is a chattel mortgage?
A chattel mortgage is a finance arrangement where you own the truck from the outset while the lender takes a mortgage over it as security until the loan is repaid. The chattel, in this case the vehicle, is yours, and it sits on your balance sheet as an asset from day one. Once you clear the loan, the lender's security is released and you hold the truck outright. This structure is popular with owner-operators and businesses that want the asset on their books and intend to keep the truck long term. It is one of the most widely used commercial vehicle finance products in Australia, valued for its ownership certainty and flexible structuring options.
What is a finance lease?
Under a finance lease, the lender buys the truck and leases it to you for an agreed term. You have full use of the vehicle and make regular lease payments, but the lender remains the legal owner throughout. At the end of the term you typically face a residual value, and depending on the agreement you may pay it out to take ownership, refinance it, or return the vehicle. Because the lender owns the asset, a finance lease can keep the truck off your balance sheet in certain arrangements, which some businesses prefer. It suits operators who want use of the vehicle without immediate ownership, or who plan to upgrade at the end of the term.
How does ownership differ?
Ownership is the clearest dividing line between the two. With a chattel mortgage, you own the truck immediately and the lender merely holds security over it, so the asset is yours to record and eventually hold free and clear. With a finance lease, the lender owns the vehicle for the life of the agreement, and your right to it flows from the lease rather than from title. This affects how the truck appears in your accounts and what happens at the end of the term. If holding the asset outright matters to you, whether for balance-sheet reasons or because you keep trucks for many years, the chattel mortgage delivers that from the start, while the lease defers it.
GST and tax treatment compared
The two structures are treated differently for GST and tax, which is often the deciding factor. With a chattel mortgage, because you own the asset, you may be able to claim the GST on the purchase price up front through your BAS, and you generally claim depreciation and interest, subject to your circumstances. With a finance lease, GST is typically applied to the lease payments rather than the purchase, and the payments themselves are usually treated differently for tax. These distinctions can meaningfully change your cash flow and deductions. Because everyone's tax position varies, you should check with your accountant to confirm which structure produces the better outcome for your specific business before committing.
Which suits your cash flow?
Cash flow considerations differ between the structures. A chattel mortgage can be shaped with a deposit and a balloon or residual payment to tune your monthly repayments to your income, and any up-front GST claim can help your position early on. A finance lease spreads cost across regular payments with a residual at the end, which can keep periodic outgoings predictable but leaves a lump sum to manage later. Owner-drivers with steady work and a long-term view often favour the chattel mortgage for the ownership and flexibility. Businesses that upgrade frequently or want to preserve certain balance-sheet treatment may lean toward the lease. Mapping each against your real cash flow, with your accountant, points to the better fit.
How to decide between the two
The right structure depends on how long you will keep the truck, how you want the asset treated in your accounts, and which tax outcome benefits your business. If you want ownership, plan to keep the vehicle for years, and want the asset on your books, a chattel mortgage is often the natural choice. If you prefer to use rather than own, upgrade regularly, or want particular accounting treatment, a finance lease may suit. Because both the lender's appetite and the tax implications matter, it pays to get advice on both fronts. A broker can lay out the finance side while your accountant confirms the tax side, so your decision rests on complete information.
Deciding between a chattel mortgage and a finance lease is easier with the finance options in front of you and your accountant's tax view alongside.
