Sole trader car finance in Australia: what you can (and can't) do
If you are a sole trader who has heard about the tax savings from novated leases and wondered if they apply to you — the short answer is no. But that does not mean you are out of options. Finance lease, chattel mortgage, and business car loans all offer genuine tax benefits for self-employed Australians. This guide explains exactly what is available, how each option works, and which is likely to suit your situation.
1. Why sole traders cannot get a novated lease
A novated lease is a three-way arrangement between you, your employer, and a finance company. Your employer makes lease payments from your gross salary before PAYG tax is calculated — this is the salary sacrifice mechanism that generates the tax saving.
As a sole trader you are your own business. There is no employer-employee relationship to form the third side of the arrangement. The ATO specifically requires that the benefit be provided to an employee by their employer. Sole traders, contractors operating through their own ABN, and business owners who pay themselves distributions rather than salary are all excluded.
Common misunderstanding
Operating through a company or trust structure does not automatically make you eligible for a novated lease. Whether you can access one depends on whether you are genuinely employed on a PAYG basis and whether your employer is set up for salary packaging. If you are unsure, ask a tax adviser.
2. The four main options for sole traders
The good news is that the Australian tax system does offer meaningful deductions for business vehicle use — just through different mechanisms to salary sacrifice. Here are the four main structures available:
Chattel mortgage
You own the vehicle from day one. A lender provides the funds and takes a mortgage over the asset as security. GST-registered businesses can claim the full GST credit upfront. Interest is deductible. Depreciation is claimed over time (or instantly if the asset qualifies).
- You own the car — no residual obligation unless you set one
- GST claim in the first BAS after purchase
- Interest deductible on the business-use portion
- Optional balloon payment to reduce monthly repayments
Finance lease
The finance company owns the vehicle and leases it to you. Lease payments are fully deductible as a business expense (business-use portion). ATO residual percentages apply at the end of the term. No GST upfront — it is claimed progressively through repayments.
- Full lease payments deductible (no need to split interest/principal)
- ATO sets minimum residual percentages based on annual km
- No ownership during the lease term
- Suits businesses where vehicle ownership is not important
Business car loan
A standard loan where you own the vehicle and repay principal plus interest. Interest is deductible on the business-use portion. Simpler than chattel mortgage in some respects — though the tax treatment is largely equivalent for most sole traders.
Cash purchase
Pay the full amount from business or personal savings. No interest to pay, no lender. But tying up capital in a depreciating asset has an opportunity cost — that cash could be earning returns or reducing a mortgage. Use the Veercal opportunity cost guide to model this.
3. Chattel mortgage — the most common choice
For most sole traders who are GST-registered and use a vehicle predominantly for business, a chattel mortgage is the most tax-effective structure. Here is why:
GST recovery
If you are registered for GST, you can claim the GST component of the vehicle purchase price in your first BAS after settlement — rather than waiting for it to come through in depreciation. For a $44,000 vehicle the GST is $4,000 — cash in your hand within months of purchase. The GST claim is capped at $6,353 for FY2026-27 (one-eleventh of the ATO car cost limit of $69,883), regardless of what you paid.
Interest deductibility
The interest component of each repayment is deductible for the business-use percentage of the vehicle. On a $40,000 loan at 7.5% over 5 years with 80% business use, you are deducting roughly $1,200–$1,400 per year in the early years of the loan.
Depreciation
You can claim depreciation on the vehicle based on the business-use percentage. The ATO car cost limit caps the depreciable value of passenger vehicles at $69,883 for FY2026-27. Vehicles above this — including luxury cars — can only be depreciated up to this cap.
| Vehicle price (drive-away) | $44,000 |
|---|---|
| Business use percentage | 80% |
| GST claimed in first BAS (capped at $6,353) | $4,000 (1/11 of $44k) |
| Interest deduction yr 1 (est., 80% of interest) | ~$2,240 |
| Depreciation deduction yr 1 (15% of $44k × 80%) | ~$5,280 |
| Total yr 1 tax benefit (est.) | ~$11,520 in deductions |
Figures are illustrative. Actual deductions depend on your business structure, use percentage, and tax situation. Consult a registered tax agent.
4. Finance lease — similar structure, different ownership
A finance lease works similarly to a chattel mortgage in practice — you use the vehicle, you have a residual at the end, and the ATO sets minimum residual percentages based on annual kilometres. The key difference is ownership: the finance company owns the car throughout the lease.
This has a few practical consequences:
- You cannot claim GST on the purchase price upfront — it flows through the lease payments progressively
- Lease payments are fully deductible as a business expense (business-use portion) without needing to split interest and principal
- At the end of the term you have the same three options as a novated lease: pay the residual and own the car, re-lease it, or hand it back
ATO residual percentages for finance leases
The same ATO minimum residual percentages apply to finance leases as to novated leases — based on annual km over the term. For 20,000 km/yr the minimum residual is 46.69% of the vehicle price. These are minimums — the actual residual in your contract may be higher.

5. Business and personal car loans
A business car loan is straightforward — you borrow money, purchase the car, own it outright, and repay the loan. For tax purposes it is treated similarly to a chattel mortgage: interest is deductible, depreciation is claimed, and GST can be recovered (if GST registered, on the business portion, capped at the car limit).
The distinction between a "business car loan" and a chattel mortgage is largely a product labelling one. In both cases you own the vehicle and a lender has security over it. The tax treatment is effectively the same. The chattel mortgage name is more commonly used in commercial lending.
6. Paying cash — when it makes sense
Cash is the simplest option and eliminates interest costs entirely. For sole traders with strong cash reserves, no debt aversion, and a vehicle under $20,000 (eligible for the instant asset write-off), cash plus immediate deduction can be the cleanest outcome. However:
- Tying up $40,000+ in a depreciating vehicle has a real opportunity cost
- If you have a mortgage, that $40,000 in an offset account is effectively earning your mortgage rate (often 6%+) risk-free
- Financing at 7–8% and keeping cash invested may be better depending on your situation
7. Tax deductions every sole trader should know
Logbook method vs cents per kilometre
The ATO allows two methods for claiming car running expenses:
| Method | How it works | Best for |
|---|---|---|
| Logbook method | Keep a 12-week logbook to establish your business-use %. Apply that % to all running expenses and depreciation for 5 years. | High business use, expensive vehicles, maximising deductions |
| Cents per km | Claim a flat 91 cents per business km (FY2026-27), up to 5,000 km. No receipts required. | Low business km, simple situation, occasional business use |
For most sole traders who use a vehicle regularly for business, the logbook method produces a larger deduction. Set up a logbook when you acquire the vehicle — you will use it for 5 years before needing to redo it.
Claimable running expenses
Under the logbook method you can claim the business proportion of: fuel, registration, insurance, servicing and repairs, tyres, car wash, loan interest, and depreciation. You cannot claim private-use expenses.
8. The $20,000 instant asset write-off (FY2026-27)
For FY2026-27, eligible small businesses with an aggregated annual turnover under $10 million can immediately deduct the full cost of assets under $20,000. The ATO applies this limit to assets first used or installed ready for use on or after 1 July 2023.
Most cars exceed the threshold
Most passenger vehicles cost more than $20,000, so they will not qualify for the instant write-off regardless. A car over $20,000 goes into the small business depreciation pool: 15% deduction in year one, 30% each year after. The instant write-off is more relevant for commercial vehicles (utes, vans) under $20,000, tools, or equipment.
Commercial vehicles with a load capacity over one tonne — such as most dual-cab utes — are not subject to the ATO car cost limit. If a tradesperson buys a $19,000 work van that is used entirely for business, they can write off the full amount in FY2026-27. Speak with a registered tax agent to confirm eligibility for your specific vehicle.

10. How to decide
The right structure depends on three things: how much you use the vehicle for business, whether you are registered for GST, and whether you prefer to own the vehicle outright or have flexibility at the end of the term.
- High business use, GST registered, want to own the car → Chattel mortgage is usually the best fit
- Want lower monthly payments and flexibility at end of term → Finance lease with a residual
- Occasional business use, low km → Personal car loan + cents-per-km deduction may be simpler
- Vehicle under $20,000, high business use → Cash or chattel mortgage and claim the instant write-off (if eligible)
A note on company structures
If you operate through a company or trust rather than as a sole trader, additional options and considerations apply — including the potential for you to be employed by your own company and access a novated lease, though this has specific conditions. Company cars provided to employee-directors attract FBT. This is a complex area and professional advice is essential before making structural decisions for tax purposes.
Common questions
Can a sole trader get a novated lease in Australia?
No. A novated lease requires a three-way arrangement between you, your employer, and a finance company. Sole traders have no employer to make salary sacrifice deductions, so novated leases are not available. PAYG employees with a participating employer are the only people who can access a novated lease.
What are the best car finance options for sole traders in Australia?
The main options for sole traders are: chattel mortgage (you own the car, claim GST upfront, deduct depreciation and interest), finance lease (similar to novated but no salary sacrifice — residual at end), business car loan, and cash. Chattel mortgage is most commonly used by sole traders for business vehicles as it allows GST recovery and interest deductions.
Can a sole trader claim a car as a tax deduction?
Yes — for the business-use portion. Sole traders can claim car running expenses (fuel, insurance, registration, maintenance) using the logbook method or cents-per-kilometre method. If using the logbook method, you can also claim depreciation on the vehicle. GST-registered sole traders can claim a GST credit on the business portion of the purchase price, capped at the car limit ($69,883 for FY2026-27). General information only — consult a tax professional for your situation.
What is a chattel mortgage and is it good for sole traders?
A chattel mortgage is a business finance product where a lender provides funds to purchase a vehicle, and takes a mortgage over the asset as security. Unlike a finance lease, you own the vehicle from day one. GST-registered businesses can claim the full GST input tax credit on the purchase price (capped at the car limit) upfront in their next BAS, and can deduct the interest component of repayments. It is one of the most tax-effective structures for sole traders purchasing a business vehicle.
What is the instant asset write-off for cars in 2026-27?
For FY2026-27, eligible small businesses (turnover under $10 million) can immediately deduct assets costing under $20,000. Most passenger cars exceed this threshold, so they are placed into the small business depreciation pool at 15% in the first year and 30% thereafter. Commercial vehicles over one tonne are not subject to the car cost limit and can qualify for the instant write-off if under $20,000. The ATO applies this $20,000 limit to assets first used or installed ready for use on or after 1 July 2023. General information only — verify with a registered tax agent.
