If you’re self-employed in Australia and buying a work vehicle, you have two main finance choices: a chattel mortgage or a standard car loan (consumer loan). They look similar at the surface — both let you borrow money to buy a car and pay it back over time — but the tax treatment, ownership structure, and total cost can be very different.

For the right borrower, a chattel mortgage saves thousands. For the wrong borrower, it adds complexity for no benefit. Here’s how to tell which side of the line you’re on.

The short answer

	Chattel mortgage	Car loan (consumer)
Best for	Self-employed / ABN holders	PAYG employees
Vehicle ownership	You own from day one	You own from day one
GST claimable	Yes (if GST-registered)	No
Interest tax deductible	Yes (business portion)	No (unless solely business use)
Depreciation deductible	Yes	No
Instant asset write-off	Yes	No
Balloon payment	Available	Available
Documentation	ABN + minimal	Tax returns / payslips
NCCP regulated	No (commercial)	Yes (consumer protection)

If you have an ABN and the vehicle is for business use, a chattel mortgage is almost always the better product. If you’re PAYG, a consumer car loan is the right choice.

What is a chattel mortgage?

A chattel mortgage is a commercial finance product where the lender provides funds to buy a “chattel” (the vehicle), and takes a registered security interest over it until the loan is repaid.

Key features:

You own the vehicle from settlement — your name is on the rego, not the lender’s
The lender registers a security interest on the PPSR (Personal Property Securities Register) — they can repossess if you default
Treated as a business asset for tax — you can claim GST, depreciation, and interest deductions
Not regulated by the NCCP Act — because it’s a commercial loan, not a consumer loan

Chattel mortgages are the standard finance product for tradies, sole traders, contractors, real estate agents, couriers, and small business owners across Australia.

What is a (consumer) car loan?

A consumer car loan is a personal loan secured against the vehicle. It’s regulated under the National Consumer Credit Protection (NCCP) Act, which gives you certain protections — but those protections come with constraints:

Lender requires income verification — typically payslips for PAYG borrowers
Strict responsible lending checks — the lender must verify you can afford repayments based on your declared expenses
No business tax benefits — you can’t claim GST or depreciation
Interest is not deductible unless the vehicle is used solely for income-producing activities (rare)

Consumer car loans are the right product if you’re a PAYG employee buying a personal vehicle.

Tax benefits — the real reason chattel mortgage wins for ABN holders

Here’s the difference in plain dollars. Same vehicle: a $66,000 ute (including GST), bought by a sole trader using 100% for business.

Under a chattel mortgage:

GST refund: $6,000 claimable on next BAS
Interest deduction: Yes — 100% of the business-use portion
Depreciation: Yes — full depreciation schedule available
Instant asset write-off: Up to $20,000 immediately deductible (subject to current rules)
Effective net cost: Significantly lower after tax

Under a consumer car loan:

GST refund: None (consumer purchase)
Interest deduction: Generally no — unless the vehicle is solely for income-producing activities
Depreciation: Limited — and only if you can substantiate business use
Instant asset write-off: Generally not applicable
Effective net cost: Higher

For a tradie buying a $66K ute, the GST refund alone can be worth $6,000 — a chattel mortgage delivers that directly within weeks of purchase.

Talk to your accountant about the exact figures for your situation. Tax outcomes depend on business structure, GST registration, business-use percentage, and current ATO rules.

When a car loan still beats a chattel mortgage

You’re PAYG. A chattel mortgage requires an ABN. If you’re an employee — even if you’ll use the car partly for work — a consumer car loan is the only option (your employer might offer salary packaging as an alternative).

The vehicle is purely personal. If you’re a self-employed nurse and you’re buying a car for school runs, family weekends, and zero work travel, the tax benefits of a chattel mortgage don’t apply.

You want NCCP consumer protections. Consumer loans give you specific protections under Australian credit law — including hardship provisions and responsible lending obligations. Chattel mortgages don’t include these protections, because they’re commercial products.

Common mistakes self-employed borrowers make

Mistake 1 — Walking into a dealer and accepting the dealer’s finance.
Dealers often default to consumer car loans because they’re easier to push through. Self-employed buyers end up with the wrong product and miss thousands in tax benefits.

Mistake 2 — Choosing a personal loan instead.
Same issue — no tax benefits, higher real cost.

Mistake 3 — Choosing an operating lease.
With an operating lease, you don’t own the vehicle. The lessor does. So you can’t claim depreciation or the instant asset write-off. There are limited cases where operating leases make sense, but for most ABN holders, chattel mortgage wins.

Mistake 4 — Buying personally and trying to claim later.
The ATO will look at how the vehicle was financed and registered. Buying under your personal name and trying to claim full business deductions is messier than buying it under the right structure from day one.

What about novated lease vs chattel mortgage?

Novated leases are a separate product — typically only available to PAYG employees who can salary-sacrifice repayments through their employer. They don’t apply to most self-employed borrowers.

If you’re a PAYG employee with an employer that offers novated leasing, that’s worth exploring as a tax-efficient alternative. If you’re self-employed under an ABN, chattel mortgage is the right product — novated lease isn’t available to you.

FAQs

Can I switch from a car loan to a chattel mortgage?
You’d need to refinance — pay out the existing loan and replace it with a chattel mortgage. Possible but typically only worth it on larger balances.

Is a chattel mortgage harder to get than a car loan?
Often easier for self-employed borrowers — because lenders use ABN-based assessment instead of payslip-based assessment.

Can I add a balloon payment to either?
Yes — both products support balloon payments. Common balloon range: 20–40% of the loan amount.

What happens at the end of the chattel mortgage term?
You either pay the final balloon (if any), refinance the balloon, or sell the vehicle and use the proceeds. Same as any secured loan.

Are chattel mortgage rates higher?
Often very similar — sometimes lower, depending on the lender and your credit profile. CarFund quotes both products where eligible so you can compare.
