Whether you’re buying your next car for the school run or adding a vehicle to your business fleet, the finance decision matters just as much as the car itself. The right structure can save you thousands in interest, unlock tax deductions, and get you approved faster than walking into a dealership and taking whatever rate they offer.
This guide breaks down car finance for both personal and business buyers, because the two paths are more connected than most people realise, and a lot of business owners are financing their car the wrong way without knowing it.
If you’re buying a car for personal use, you’ll typically choose between:
Secured Car Loan — The most common option. The car itself is used as security, which usually means a lower interest rate than an unsecured loan. Terms typically run 1–7 years.
Unsecured Personal Loan — No asset required as security, but you’ll pay a higher interest rate to offset the lender’s risk. Worth considering if you’re buying a car that doesn’t fit standard lending criteria (very old, high km, private sale).
Dealer Finance — Convenient, but dealers typically only have access to one or two lenders on their panel, meaning you’re seeing a fraction of what’s actually available to you, at a rate that includes their margin.
Novated Lease — If you’re a PAYG employee, a novated lease lets your employer make repayments from your pre-tax salary, which can meaningfully reduce your taxable income. Best suited to newer cars and employees with an employer who supports salary packaging.
This is where most business owners either overpay or miss out on tax benefits entirely, usually because nobody explained the options clearly before they signed at the dealership.
Chattel Mortgage — The most common structure for business vehicles. You own the car from day one, the lender takes a mortgage over it as security, and you can typically claim GST back on the purchase price upfront (if registered for GST) plus depreciation and interest as tax deductions. Ideal if the vehicle will be used 50%+ for business purposes.
Finance Lease — You lease the vehicle for a fixed term with a residual value at the end. Popular for businesses that want to preserve cash flow and avoid tying up capital in depreciating assets.
Novated Lease (via your own business) — If you’re a business owner who also pays yourself a salary, you can novated lease a vehicle through your own company, combining personal use with salary packaging benefits.
Structuring correctly can mean the difference between claiming a car as a full business deduction versus getting caught out at tax time with a structure that doesn’t match how the vehicle is actually used. This is general information, not tax advice — always confirm the right structure with your accountant based on your specific business use percentage.
A quick gut-check:
| Situation | Likely Best Fit |
| Buying purely for personal/family use | Secured car loan |
| PAYG employee, employer offers salary packaging | Novated lease |
| Sole trader/company buying a work vehicle (50%+ business use) | Chattel mortgage |
| Want to preserve cash flow, avoid ownership | Finance lease |
| Buying a car that’s a mix of personal and business use | Worth a broker conversation — this is the grey area where structure matters most |
If you’re not sure which bucket you fall into, that’s normal — most people aren’t across ATO business-use thresholds or novated lease mechanics, and that’s exactly where a broker adds value beyond just finding a rate.
Different vehicles come with different financing considerations — age limits, luxury car tax thresholds, EV-specific incentives, and lender appetite all vary by make and model.
Tesla Finance (Model 3, Model Y) — Teslas are financeable through both standard car loans and business chattel mortgages. As EVs, they may qualify for lender-specific green/EV finance rates with select lenders, and business buyers should check current Fringe Benefits Tax (FBT) exemptions for eligible electric vehicles under the ATO’s EV FBT exemption — this can make a novated lease or business purchase significantly more cost-effective than an equivalent petrol vehicle. New Tesla models generally attract strong finance terms given high resale demand.
Prestige & Luxury Vehicles (Land Rover, Ferrari, Lamborghini) — Luxury and exotic vehicles are financeable, but expect more lender variation — not every lender on a standard panel will finance a Ferrari or Lamborghini, and those that do may require a larger deposit or shorter term. Vehicles priced above the ATO’s luxury car limit also have different depreciation and GST treatment for business buyers. This is where going through a broker with access to specialist prestige/asset lenders matters more than with a mainstream vehicle.
Utes & Commercial Vehicles (Ford Ranger Raptor, Toyota Hilux, VW Amarok) — Popular with business buyers for the instant asset write-off and chattel mortgage structuring. Dual-cab utes with a payload over one tonne generally qualify for more favourable FBT treatment when used predominantly for work purposes.
Used & Private Sale Vehicles — Financing a private sale (Facebook Marketplace, Gumtree, Carsales private listing) is possible but not every lender supports it, dealer-only lending panels are common, which is another reason a broker with a wider panel matters for private purchases.
Dealers see one or two lenders — A broker compares across a panel of banks and specialist lenders to find the actual best fit for your situation — not just what’s convenient for the dealership’s finance department.
Declined by the dealer doesn’t mean declined everywhere — Self-employed, ABN under 2 years, non-standard credit history — these are exactly the profiles a broker can often still get approved through the right lender.
One application, multiple options — Rather than approaching lenders one at a time, a broker runs your application against multiple lenders in parallel.
Business structuring guidance included — Getting the chattel mortgage vs lease decision right the first time avoids a messy conversation with your accountant later.
Can I finance a car through my business if I’m self-employed?
Yes. Sole traders, partnerships, and companies can all access chattel mortgage, CHP, and lease structures. Lenders will typically want to see your ABN history, recent financials, and evidence of business use.
What’s the difference between a chattel mortgage and a car loan?
A car loan is typically for personal use and the loan sits on your personal credit file. A chattel mortgage is a business finance product where the business owns the asset and the loan is structured for business tax purposes.
Can I claim GST back on a business car purchase?
If you’re registered for GST and the vehicle is used for business purposes, you can generally claim the GST credit on the purchase price under a chattel mortgage — subject to the car depreciation limit set by the ATO. Confirm specifics with your accountant.
Is it better to buy or lease a car for my business?
It depends on whether you want to build equity in the asset (buy, via chattel mortgage) or preserve cash flow and avoid depreciation risk (lease). Both have valid use cases depending on how you use the vehicle and your cash flow position.
Can I finance a luxury or imported vehicle through my business?
Yes, though luxury vehicles above the ATO’s luxury car limit have different depreciation and GST treatment. This is a common area where getting advice before you buy saves a lot of after-the-fact cleanup.
Whether you’re buying your next car personally or adding one to your business, the right structure makes a real difference to what you pay — and what you can claim back.
If you’ve been shopping around for a car loan, business loan, or asset finance lately, you’ve probably seen two numbers sitting side by side in every ad: the interest rate and the comparison rate. They’re rarely the same number, and if you don’t know why, you can end up comparing the wrong figure, and paying […]
