Chattel Mortgage Tax Benefits for ABN Holders: GST, Depreciation and Cash Flow in 2026-27

Key takeaways: A chattel mortgage lets an ABN holder own a vehicle or piece of equipment from day one while the lender holds security over it. For GST-registered businesses, the GST on the purchase price can generally be claimed on the next BAS, and interest and depreciation may be deductible to the extent the asset is used for business.

What is a chattel mortgage?

A chattel mortgage is a business loan secured against a movable asset (a 'chattel'), such as a ute, truck, trailer, excavator, forklift or piece of medical equipment. You take ownership at settlement, and the lender registers its security interest on the PPSR until the loan is repaid. It is the most common business vehicle and equipment finance structure in Australia because it combines ownership with tax efficiency.

The three main tax efficiencies

1. GST credit upfront

Because you own the asset immediately, a business registered for GST and using the asset for business purposes can generally claim the full GST credit in the BAS for the period of purchase, rather than over the life of the loan. For cars, the credit is capped: for 2026-27 the ATO car limit is $69,883, so the maximum GST credit on a passenger car is $6,353. Utes and vans designed to carry one tonne or more, or nine or more passengers, are generally not subject to the car limit.

2. Interest deductions

The interest component of each repayment may be claimed as a business expense, in proportion to business use.

3. Depreciation and the instant asset write-off

As owner, you claim depreciation on the asset. From 1 July 2026, small businesses with aggregated turnover under $10 million can immediately deduct eligible assets costing less than $20,000, applied per asset, with the measure now law according to the ATO. Assets above that threshold go into the small business pool or are depreciated over their effective life. Passenger cars are depreciated on a cost capped at the car limit.

Chattel mortgage vs lease vs hire purchase

• Ownership: chattel mortgage at settlement; hire purchase at the final payment; finance lease stays with the lender unless you buy out the residual

• GST: chattel mortgage and hire purchase generally allow upfront GST credits; leases claim GST on each rental

• Deductions: chattel mortgage and hire purchase claim interest and depreciation; leases claim rental payments

• Balance sheet: owned assets and the matching liability appear on your balance sheet

Cash flow levers inside a chattel mortgage

• Balloon payment: a final lump sum, often 20% to 40% for vehicles, that reduces monthly repayments

• Term: typically one to seven years, matched to the asset's useful life

• Deposit or trade-in: optional, but can lower the rate and repayments

• GST refund timing: some businesses use the GST credit to pay down the loan early or fund the first months of repayments

A worked example for an ABN holder

Consider a Brisbane electrical contractor buying a $66,000 (GST-inclusive) ute for 100% business use with a chattel mortgage. The GST component of $6,000 can generally be claimed on the next BAS. Interest on each repayment and depreciation on the $60,000 GST-exclusive cost may be deductible each year. The business keeps its working capital in the bank while the ute starts earning from week one. Figures are illustrative only; your accountant will confirm the treatment for your circumstances.

Who is eligible?

• Sole traders, partnerships, companies and trusts with an active ABN

• GST registration to claim the upfront GST credit

• Assets used more than 50% for business purposes

• Acceptable credit history, with low-doc options for established ABN holders

• New and used vehicles, trucks, machinery and equipment from dealers or private sellers

Common mistakes to avoid

• Claiming the full GST credit on a mixed-use vehicle without apportioning private use

• Setting a balloon that is larger than the asset's likely resale value

• Forgetting that the car limit caps both depreciation and the GST credit on passenger cars

• Choosing a term longer than the asset will realistically be used
