Choosing Between Chattel Mortgage, Lease and Hire Purchase

Most small business owners don’t lose money on equipment, they lose it on the structure.

The mistake I see most is this: a business owner signs whatever the dealer puts in front of them – often a lease – without understanding how it hits tax, cashflow, and future borrowing power. Six months later, their accountant is trying to unwind it and their home loan application is suddenly harder.

Here’s the short version up front: a chattel mortgage usually suits businesses that want ownership and strong GST/depreciation claims, a finance lease suits those wanting fully deductible rentals with flexible upgrades, and hire purchase now fills a narrower, more legacy niche. The right answer depends on your cashflow, GST position, and how long you’ll keep the asset.

The three main options in plain English

Before we get into nuance, let’s define each structure in practical terms.

1. What is a chattel mortgage?

A chattel mortgage is a standard business loan secured by the asset (the ‘chattel’). You own the equipment from day one, the lender takes a mortgage over it, and you repay principal and interest over a set term (often 3–7 years).

Key features:

• Ownership: business owns the asset immediately.
• GST: you generally claim GST on the full purchase price up front (subject to normal rules).
• Tax: interest and depreciation are deductible; you may also use temporary full expensing/instant asset write-off where available.
• Balance sheet: the asset and loan sit on your balance sheet.

This structure is very common for vehicles, machinery and standard equipment. For tradies and many professional practices, it’s often the default choice.

2. What is a finance lease?

A finance lease is effectively a long-term rental with a residual payment at the end.

The lender (or lessor) owns the asset; your business rents it for an agreed term, then either pays a residual to take ownership, refinances that residual, or hands the asset back (depending on the contract).

Key features:

• Ownership: lender owns the asset during the term; you may take ownership at the end.
• GST: payable on each lease payment (and usually the residual) over time.
• Tax: lease rentals are generally fully deductible when the asset is used to produce assessable income.[1]
• Balance sheet: under accounting standards, it will usually show as a right‑of‑use asset and lease liability, but tax treatment remains rental‑style.

Finance leases can work well where equipment will date quickly (IT, some medical tech) or where you value fully deductible repayments over depreciation.

3. What is a hire purchase?

A hire purchase (or commercial hire purchase) is where the financier buys the asset and hires it to you, with ownership transferring to you after you make the final payment.

Tax and GST treatment today is often similar to a chattel mortgage for most businesses using accrual accounting, which is why hire purchase has become less common.

Key features:

• Ownership: you gain ownership at the end of the term (often effectively treated as ownership from near day one for tax).
• GST: usually claimable on the full purchase price upfront (for eligible taxpayers).
• Tax: interest and depreciation (or effective interest component) are deductible.

In practice, when clients ask "hire purchase vs chattel mortgage?", the chattel mortgage usually wins for simplicity and lender choice, unless there’s a specific legacy or accounting reason to use hire purchase.

Different finance structures change who owns the asset, when cash leaves your account and how tax deductions are claimed.

How each option impacts tax, GST and cashflow

What I tell my clients is: structure is about timing – when you claim deductions, when you pay GST, and when cash actually leaves your bank account. Let’s look at each.

Tax and GST treatment at a glance

Below is a simplified comparison for a typical small business registered for GST and paying tax on an accruals basis. Always confirm details with your tax adviser as rules change.

Worked example: $80,000 work vehicle

Assume:

• Price: $80,000 + $8,000 GST
• Term: 5 years
• Interest rate: 8% p.a. (illustrative only, not an offer)
• Residual/balloon: 20% ($16,000) for structures that allow it
• Business is profitable, GST-registered, company tax rate 25%

Option A: Chattel mortgage

• Day one: you claim the $8,000 GST on your next BAS (subject to normal rules).
• Tax: you claim interest each year plus depreciation, potentially accelerated under current tax incentives.
• Repayments: approximately $1,303 per month (P&I) with a 20% balloon at the end (approximate, for illustration).
• Cashflow: lower monthly repayments due to balloon, but a lump sum at the end to refinance, pay out, or clear on sale.

Option B: Finance lease

• No big GST claim upfront; instead, you claim the GST embedded in each lease payment over time.
• Lease rentals (ex‑GST) are generally fully deductible.
• Monthly lease payment for the same term and residual might be around the same ballpark as a chattel mortgage repayment, but the timing and nature of deductions differ – rentals vs depreciation.

Option C: Hire purchase

• For many small companies, this now lands very close to the chattel mortgage from a tax perspective: GST upfront, interest + depreciation deductions.
• However, documentation and lender appetite can be clunkier.

The practical question:

• Do you value a big upfront GST credit and depreciation? Chattel mortgage / hire purchase have the edge.
• Do you prefer smooth, fully deductible rentals without worrying about depreciation schedules? The finance lease often wins.
