Quick Answer
The decisive difference is ownership during the term. A chattel mortgage gives you legal title from settlement, subject to the lender's security. A finance lease leaves title with the financier and gives you contractual use of the asset. Compare the cash flow, GST treatment, tax treatment and end-of-term obligations for the actual contracts offered—there is no universally superior structure.

Full Feature Comparison
| Feature | Chattel Mortgage | Finance Lease |
|---|---|---|
| Asset ownership during term | ✓ Borrower owns asset | Lender owns asset |

| Income-tax deductions | Business-use interest may be deductible | Business lease deductions depend on the agreement and tax treatment |
| Tax depreciation | The borrower may claim eligible decline in value as owner | The financier is generally the tax owner; accounting right-of-use treatment is a separate issue |
| Instant asset write-off | May apply to an eligible owner and asset if an enacted threshold is met | Generally not available to the lessee because it does not own the asset for tax purposes |
| Balloon / Residual | Optional — any amount 0–50% | ATO mandates minimum residual |
| ATO minimum residual guideline (5yr term) | N/A — no prescribed lease residual | 28.13% for relevant motor-vehicle leases; contract and asset class matter |
| End of term | Pay balloon (if any) — own outright | Pay ATO residual to take title |
| Early payout | ✓ Yes (break cost may apply) | ✓ Yes (break cost may apply) |
| Balance sheet treatment | Asset + liability on balance sheet | Asset + liability (AASB 16) |
| Modify or sell asset | ✓ Yes — you own it | Needs lender consent |
| Common fit | Businesses wanting immediate ownership and control of the asset | Businesses whose use and replacement plan fits the lessor's contract and end-of-term options |
Finance Lease: ATO Minimum Residual Values
Unlike a chattel mortgage where any balloon is optional, finance leases have ATO-mandated minimum residual values. These are set to prevent leases from functioning as purchase agreements with negligible residuals.
| Lease Term | ATO Minimum Residual (% of cost) |
|---|---|
| 1 year | 65.63% |
| 2 years | 56.25% |
| 3 years | 46.88% |
| 4 years | 37.50% |
| 5 years | 28.13% |

A chattel mortgage has no minimum balloon. You can set it at 0% and own the asset outright at the end of the term with no residual obligation.
GST Timing: Compare the Actual Tax Invoices
The timing can differ materially, but the amount is not safely compared without the purchase invoice, lease schedule, business-use percentage, GST registration and any motor-vehicle credit limit.
For a fully creditable $110,000 acquisition with $10,000 GST, a GST-registered business may be able to claim up to $10,000 in the relevant BAS period. Private use, vehicle credit limits and other restrictions can reduce this.
GST is generally included in taxable lease charges, and eligible credits are attributed under the normal GST rules. A residual purchase is a separate transaction. Do not assume the total credit will equal the purchase GST without checking the lease documents.
Illustrative Timing Example: $110,000 Asset
| Structure | GST in Year 1 | GST in Year 2 | GST in Year 3+ |
|---|---|---|---|
| Chattel Mortgage | Up to $10,000 if fully creditable | $0 from the original purchase | $0 from the original purchase |
| Finance Lease | Credit on eligible GST-bearing lease charges | Credit on eligible GST-bearing lease charges | Continues with taxable charges; residual purchase separate |
Illustration only. It assumes the acquisition is fully creditable and is not limited by private use or special vehicle rules. Lease credits depend on the GST shown on each tax invoice and the business's attribution basis.
Which Is Better: Chattel Mortgage or Finance Lease?
Consider a Chattel Mortgage if:
- You are registered for GST and want the upfront credit
- You want to own the asset immediately (modify, sell, use as security)
- You want to own and depreciate an eligible asset under the law in force for the relevant income year
- You want the flexibility to set any balloon (including 0%)
- You want the simplest end-of-term outcome — just pay off the loan
- You're buying used assets where you want equity from day one
Consider a Finance Lease if:
- You want ATO-set residual certainty for fleet management planning
- You're a business that consistently replaces assets and the proposed end-of-term options match that cycle
- Your accountant recommends the AASB 16 treatment for financial reporting
- The upfront GST credit isn't a priority (e.g. not GST-registered, or not cash-flow constrained)

FAQs
Not automatically. A chattel mortgage may suit a tradie who wants legal ownership, control of the asset and potential purchase-related GST and depreciation outcomes. A finance lease may suit a planned replacement cycle. Compare the quoted cash flows, contract restrictions, business-use percentage and end-of-term obligations, then have an accountant confirm the tax treatment.
Under AASB 16, a finance lease appears on the balance sheet as a right-of-use asset and corresponding lease liability. This changed in 2019 when AASB 16 became mandatory for most entities. An operating lease may achieve accounting presentation based on the contract and applicable standards depending on the specific lease terms.
You can't convert a finance lease to a chattel mortgage mid-term. However, you can pay out a finance lease early (subject to break costs) and enter a new chattel mortgage. When taking on new assets, simply choose the chattel mortgage structure from the start.
They can differ because the financed amount, GST treatment, fees, rate, residual and payment timing may not be equivalent. Compare the lender schedules line by line rather than matching only the advertised repayment. The calculator can model repayment scenarios, but it is not a lease quote or tax calculation.
