Car Loan vs Chattel Mortgage: Which Is Right for Your Business Vehicle?
A consumer car loan is for personal use, it has no specific tax advantages. A chattel mortgage (also called a business car loan or ABN loan) is for vehicles used primarily for business and offers significant tax benefits: you can claim the GST upfront on your next BAS, deduct the interest component of repayments, and claim the permanent $20,000 instant asset write-off on eligible vehicles from 1 July 2026. If you have an ABN and the vehicle is primarily for work, a chattel mortgage is almost always the better financial structure.
What Does 'Chattel' Actually Mean?
A chattel is a moveable piece of property, as opposed to real property like land. A chattel mortgage is simply a loan secured against a moveable asset. In finance, it means you own the vehicle from day one while the lender holds a charge (mortgage) over it as security until the loan is repaid.
Banks and lenders market this product under different names: business car loan, equipment loan, ABN loan, commercial vehicle finance. All refer to the same underlying structure. The term 'chattel mortgage' is what your accountant will use at tax time, it is the product that unlocks the tax benefits.

The Tax Calculation — Real Example on a $35,000 Ute:
A tradie buys a $35,000 ute (excluding GST). He has an ABN, is GST-registered, and uses the vehicle 90% for work. Under a chattel mortgage:
| Tax benefit | How it works |
|---|---|
| GST refund on purchase | $3,182 — the GST component of a $35,000 vehicle claimed on your next BAS. |
| Interest deductions (over 5 years) | Say $6,000 total interest at 6.5% p.a. At 90% business use, $5,400 is tax deductible — saving roughly $1,350 in tax at a 25% rate. |
| Depreciation (if over $20K threshold) | 15% in year one, 30% per year after — reduces taxable profit each year for the life of the vehicle. |
| Total tax benefit estimate | Over $4,500 in real savings $3,182 GST refund + approx $1,350 tax saving on interest — on a $35,000 vehicle at 90% business use. Your accountant can confirm the exact figure for your situation. |
Figures are illustrative. Your actual tax saving depends on your tax rate, business-use percentage and vehicle price. Always confirm with your accountant.
2026-27 BUDGET UPDATE → The $20,000 instant asset write-off is now PERMANENT from 1 July 2026. For any eligible business vehicle under $20,000 financed under a chattel mortgage, you can claim the full cost as an immediate tax deduction every financial year with no sunset date. Plan vehicle purchases with confidence.
When a Consumer Car Loan Is the Right Choice:
A consumer car loan is the right structure when:
The vehicle is for personal use, commuting, family, lifestyle, with no or minimal business use
You do not have an ABN or are not registered for GST
The vehicle is for a family member who does not use it for work
Your accountant advises the business-use percentage does not justify the chattel mortgage structure
Under a consumer loan, you still own the vehicle from day one, your repayment is fixed, and you can make extra repayments on most variable rate products. The only difference is the absence of the business tax benefits.
When a Chattel Mortgage Is Almost Always the Right Choice:
If you have an active ABN and use the vehicle for work more than 50% of the time, a chattel mortgage almost always delivers a better financial outcome. The GST refund alone is typically $2,000 to $5,000+ depending on the vehicle price. That is real money in your pocket on the next BAS, regardless of the interest rate.
The most common buyers who benefit from a chattel mortgage over a consumer loan:
Tradies — utes, vans, specialist vehicles
Transport and logistics operators — any business vehicle
Healthcare and allied health professionals — home visit vehicles
Real estate agents and property professionals — vehicles used client-facing
Any sole trader, partnership, company or trust with an active ABN and genuine business use
IMPORTANT NOTE → Structuring a personal-use vehicle as a chattel mortgage to claim GST and tax deductions when the vehicle is not genuinely used for business is a compliance risk. Your accountant is the right person to confirm the appropriate business-use percentage and structure for your situation. We can then arrange the right loan structure once confirmed.

What About a Novated Lease?
A novated lease is a third option available to employees, where the employer makes loan repayments from the employee's pre-tax salary. This is a separate structure from both consumer car loans and chattel mortgages, and is most relevant for employees (not business owners) who receive salary packaging through their employer.
For self-employed individuals and business owners, a chattel mortgage is typically more tax-effective than a novated lease. We can explain which structure applies to your specific employment situation.
Frequently Asked Questions:
-
You need an active ABN. You do not need to own a company — sole traders, partnerships, trusts and companies are all eligible. The vehicle must be used primarily for business purposes. A sole trader who uses their ute for their trade qualifies.
-
Yes. Chattel mortgage is available for new vehicles, used vehicles from dealers, and private sale vehicles. The vehicle must meet lender age and condition criteria. A PPSR check is required for private sales.
-
The deductible portion is based on your business-use percentage. If you use the vehicle 80% for business, you can claim 80% of the interest, depreciation and other running costs as a tax deduction. The GST refund on the purchase price applies to 100% of the vehicle regardless of business-use percentage (for a GST-registered business).
-
If the vehicle costs $20,000 or more, it does not qualify for the instant asset write-off. Instead it goes into the small business depreciation pool: 15% depreciation in the first year and 30% per year after that. You still claim GST upfront and deduct interest. The tax benefit is spread over multiple years rather than taken immediately.
