Chattel Mortgage vs Finance Lease for Tradies: Which Is Better in 2026?

The Short Answer

Chattel Mortgage Explained

A chattel mortgage is a business finance product where you borrow money to purchase an asset — a ute, excavator, compressor, whatever — and give the lender a "mortgage" (a security interest) over that asset. Despite what the name implies, you own the asset from the moment of purchase. The lender just has a registered security interest over it via the PPSR (Personal Property Securities Register) until the loan is repaid.

Once the final repayment is made, the security is discharged and the asset is fully yours with no strings attached.

The tax treatment is why most tradie accountants default to it:

• GST: You can claim the full GST component of the purchase price in the BAS period when the asset is purchased — not spread over the loan term. On a $110,000 (GST-inclusive) machine, that's $10,000 back in your next BAS.
• Interest: The interest component of each repayment is fully tax deductible as a business expense.
• Depreciation: You claim depreciation on the asset under the ATO's depreciation rules — or potentially an immediate deduction under instant asset write-off rules if the asset is below the current threshold.

The combination of upfront GST recovery and ongoing interest and depreciation deductions is powerful for cash flow, particularly in the first year of ownership.

The loan itself is not a deductible expense — only the interest component. The principal repayments are simply repaying borrowed money. This is a common point of confusion.

Finance Lease Explained

In a finance lease, the finance company buys the asset and leases it to you for an agreed term — typically 2–5 years. You never own the asset during the lease period. The finance company (the "lessor") does. You're the lessee.

At the end of the lease term, you typically have three options:

1. Buy the asset at the pre-agreed residual value (similar to a balloon payment)
2. Extend the lease for another term at revised payments
3. Hand the asset back — particularly useful for fleet vehicles you want to upgrade regularly

The tax treatment is different:

• GST: You claim GST on each lease payment as it's made — not upfront on the full purchase price. The timing is spread over the lease term.
• Lease payments: The full lease payment (not just an interest component) may be tax deductible as a business operating expense — though the deductible amount depends on the structure and the ATO's determination of finance lease vs operating lease treatment.
• Depreciation: Because you don't own the asset, you cannot claim depreciation. That's the lessor's benefit.
• Balance sheet: Under AASB 16, most finance leases must now be recognised on the balance sheet — the "off balance sheet" benefit has largely disappeared for businesses following Australian Accounting Standards.

Monthly repayments are typically lower on a finance lease than a chattel mortgage for the same asset value, because you're not paying down full ownership — you're paying toward the difference between the purchase price and the residual value.

The Head-to-Head That Actually Matters for Tradies

Forget the theory for a moment. Here's how the two structures play out in the scenarios tradies actually face.

Scenario 1: Buying a new dual-cab ute you'll run for 5–7 years

Verdict: Chattel mortgage. You're going to own and operate this ute until the wheels fall off (or until the residual makes refinancing worthwhile). Claim the GST upfront, claim depreciation each year, deduct the interest. At the end you own a ute outright. This is the tradie default and it's the right call here.

Scenario 2: Financing a fleet of service vans, replaced every 2–3 years

Verdict: Finance lease may make sense. Lower monthly payments, and at end of term you simply hand back the vans and upgrade. No residual risk on the second-hand van market, no private sale hassle. The trade-off is no upfront GST claim and no depreciation. For high-volume fleet operations, the operational simplicity can outweigh the tax advantage. Talk to your accountant and fleet finance specialist.

Scenario 3: Financing a $300,000 excavator as a growing earthmoving business

Verdict: Chattel mortgage, emphatically. GST claim in the purchase BAS period ($27,272 on a $300,000 purchase), depreciation deductions each year, and you own an asset that builds equity. Excavators hold value well relative to vehicles. The upfront GST recovery alone justifies the structure.

Scenario 4: Newer business, lower monthly payment is critical for cash flow

Verdict: Consider finance lease, but run the numbers. A finance lease's lower monthly payment might appear attractive if you're cash flow constrained. But you're sacrificing the upfront GST claim — which could be a significant cash injection in your next BAS period. Run both scenarios with your accountant before deciding based on the headline monthly payment.

Which One Do You Actually Need?

Here's a simple decision framework. If you answer "yes" to most of these, chattel mortgage is your structure:

• You plan to use the asset for 3+ years
• Your business is GST-registered and you want the upfront GST recovery
• You want to build equity in the asset as you pay it down
• You're buying plant, heavy equipment, or a work vehicle you'll keep long-term
• You want to potentially refinance or sell the asset later

Finance lease is worth exploring if:

• You're managing a vehicle fleet that you upgrade on a regular cycle
• You want to keep monthly payments lower and the end-of-term handback option is genuinely valuable to you
• Your accountant has reviewed both structures and recommended the lease for your specific tax position

One thing to avoid: choosing a finance lease purely because the monthly payment looks lower without understanding that you're trading the upfront GST claim and depreciation deductions to get that. The numbers often favour chattel mortgage once you account for the full tax picture over 3–5 years.

The other thing to avoid: making the decision based on a lender's recommendation without your accountant's input. Lenders have products to sell. Your accountant has your tax position to protect.
