Want the after-tax answer? The after-tax comparison calculator models GST timing and the interest-plus-depreciation versus rentals difference that a cash comparison leaves out.
Quick answer
Choose a chattel mortgage if you want to own the asset, shape cash flow with a deposit/balloon, and potentially claim GST on the purchase upfront (if registered and eligible). Choose a lease if you prefer to pay for use with rentals, keep options open at the end (pay residual, return or upgrade), and spread GST across payments.
- Chattel Mortgage: Ownership from day one, flexible balloon, interest + depreciation deductions, GST usually upfront on purchase.
- Finance Lease: Lessor owns, rentals tax-deductible, GST on each rental, residual must meet ATO guidelines.
- Operating Lease: Rental-style use, maintenance/upgrade options, return at end without ownership obligation.

Chattel mortgage vs lease at a glance
The headline difference is ownership: a chattel mortgage gives you the asset from day one, while a lease keeps the asset with the lessor.
| Factor | Chattel Mortgage | Lease (finance or operating) |
|---|---|---|
| Ownership during term | You own from day 1 | Lessor owns |
| Ownership at end | Already yours | Return, extend or pay residual (finance lease) |
| GST timing | Up front on purchase price | On each lease payment |
| Tax deductions | Interest + depreciation | Lease payment portion (subject to apportionment) |
| Balance sheet (AASB 16) | Asset + loan liability | Right-of-use + lease liability |
| Repayment flexibility | Balloon 0-30%; pay or refinance at end | Set residual (FL) or return option (OL) |
| Upgrade cycle | Sell or trade when you choose | Built into the lease terms |
| Best suited to | Long-life assets, ownership focus | Faster-moving tech, planned upgrades |
Run the numbers on your asset
Every comparison page tells you a chattel mortgage means ownership and a lease means use. Almost none of them do the arithmetic. Put your asset in below and see what each structure actually costs, when the GST lands, and what you are left holding at the end of the term.

Chattel mortgage vs lease: the real differences
The decision usually comes down to a few practical questions.
- Ownership and control: Do you want to own and keep the asset long term (chattel mortgage), or pay to use it with options at the end (lease)?
- Repayment shaping: Prefer deposit + balloon flexibility (chattel mortgage) or a set residual/rental profile (lease)?
- End-of-term outcome: Want certainty to keep (chattel mortgage) or flexibility to pay residual/return/upgrade (lease)?
- Tax + GST timing: Would claiming GST upfront and depreciating the asset suit you (chattel mortgage), or do you prefer GST and deductions embedded in rentals (lease)?
- Asset lifecycle: Is it a long-life asset you’ll retain, or fast-moving tech/vehicles you refresh on a cycle?

Ownership, tax and GST in Australia
Chattel Mortgage
- Ownership: Your business owns the asset; the lender takes a mortgage over it.
- Tax: Generally claim interest and depreciation (and any eligible immediate deduction rules if applicable to your business and asset).
- GST: Typically claimed upfront on the purchase price if registered and eligible. No GST on repayments themselves (fees/balloon may include GST).
- More detail: Chattel Mortgage Tax Benefits, Chattel Mortgage GST Treatment.
Finance Lease
- Ownership: Lessor owns the asset during the term.
- Tax: Lease rentals are generally deductible to the lessee.
- GST: GST is payable on each rental and on the residual if exercised.
- Residuals: Must usually meet ATO minimum residual guidelines for the chosen term.
- More detail: Finance Lease Tax Benefits, Finance Lease GST Treatment, Finance Lease Residual Value.
Operating Lease
- Ownership: Lessor owns; you pay rentals for use and typically return/upgrade at end.
- Tax: Rentals are generally deductible to the lessee.
- GST: GST is charged on rentals as they fall due.
- More detail: Operating Lease Tax Benefits, Operating Lease GST Treatment.
Cash flow: deposits, residuals and balloons
- Chattel Mortgage: Flexible deposit and balloon options to shape repayments. See Chattel Mortgage Balloon Payments and Minimum Deposit.
- Finance Lease: Residual is set at the start and generally must comply with ATO guidelines. See Residual Value Explained.
- Operating Lease: Rentals are designed around expected usage and return condition; there is usually no ownership residual to pay.
Tip: Compare the full cost over the intended holding period, not just the monthly repayment. Include fees, GST timing, deductions and any end-of-term obligations.
End-of-term outcomes
- Chattel Mortgage: Keep the asset once the balance (including any balloon) is paid.
- Finance Lease: Options may include paying the residual to own, refinancing the residual, or returning the asset (subject to agreement).
- Operating Lease: Commonly return and upgrade; sometimes extend. Excess wear/km charges may apply (vehicles/fleet).
If you already know you will keep the asset, a chattel mortgage often lines up better. If you prefer structured upgrade points, consider a lease.

Approval and documentation
Lenders and lessors look at similar fundamentals regardless of structure: your business profile, trading history, credit background and the asset’s details and use.
- ABN/ACN, identification and business details
- Asset details (supplier quote/invoice, age, hours/km if applicable)
- Financials or bank statements (low-doc options may be available)
- Credit history and any existing facilities

A worked example: $88,000 excavator, five years
Numbers make the difference concrete in a way a comparison table never does. Same machine, same lender, same 8.5% rate, same five-year term, same 20% tail.
| Chattel mortgage | Finance lease | |
|---|---|---|
| Amount financed | $80,000 (GST stripped out) | $80,000 |
| GST treatment | Claim the full $8,000 on your next BAS | Claim the GST on each rental as you pay it |
| Monthly | $1,426, with no GST on the repayment | $1,426 plus GST, so $1,569 out the door |
| End of term | $16,000 balloon, then it is yours | $17,600 residual (GST inclusive), or hand it back |
| Deductions | Interest plus depreciation on the asset | The rental payments |
| Cash in the first quarter | Three repayments, offset by an $8,000 GST refund | Three rentals, offset by $428 of GST |
Total cash out over the five years is $101,583 on the chattel mortgage and $111,742 on the lease, but almost none of that $10,159 gap is a real cost difference: it is the GST you claim back either way. Strip it out and the two structures cost near enough the same to service. What differs is when the GST lands and what you are holding at the end.
The chattel mortgage puts $8,000 back in your account inside one BAS cycle. On an $88,000 machine that is most of a deposit, returned to you within three months. The finance lease drips the same GST back over five years at about $143 a month, and in exchange the monthly figure you actually pay is $143 higher.
Where a lease genuinely wins is the end. If the machine will be worn out, superseded or simply not wanted in five years, the ability to hand it back and walk away is worth real money, and a chattel mortgage gives you an asset you now have to sell. If you will still be using it in year eight, the chattel mortgage is the cheaper way to get there.

Frequently asked questions
What is the main difference in chattel mortgage vs lease?
The main differences are ownership, GST/tax timing, how repayments are shaped and what happens at the end of the term. Chattel mortgage = ownership and flexible balloon. Lease = pay to use with a residual/return option.
Which option is cheaper?
It varies by term, rate, deposit, residual/balloon, GST timing and deductions. Compare total cost over the time you’ll hold the asset, not just the monthly payment.
How does GST work for each?
Chattel mortgage often allows an upfront GST claim on the purchase (if registered/eligible), with no GST on the repayments themselves. Leases charge GST on each rental and any residual. Confirm details with your accountant.
Can the same asset fit more than one structure?
Yes. Many assets can be financed under multiple structures, subject to policy and eligibility. The right choice depends on usage, holding period and desired end position.
Are residuals and balloons the same?
No. Lease residuals generally must meet ATO guidelines for the term. Chattel mortgage balloons are more flexible and set by lender policy and asset risk.

Final takeaway
If you plan to own and keep the asset, a chattel mortgage usually aligns with that goal and can optimise GST/tax timing and cash flow via a balloon. If you want structured end-of-term flexibility with options to pay residual, return or upgrade, a lease can fit better - especially for assets on a planned refresh cycle.
