Construction Equipment Finance GST Treatment

GST treatment by finance structure

Chattel mortgage (asset loan)

• Supplier issues a tax invoice with 10% GST on the equipment price.
• You generally claim the full GST on the purchase price on your next BAS (subject to creditable purpose). The lender funds the supplier at settlement, so the consideration is paid.
• Repayments (principal and interest) are not subject to GST. Lender/broker establishment or monthly fees may include GST if they are taxable supplies.
• Final balloon under a chattel mortgage is a repayment of principal—no GST.

Hire purchase

• Since 1 July 2012, input tax credits are generally claimable upfront for GST-registered businesses when the asset is provided and you hold a tax invoice.
• No GST on interest; check fees for GST.
• Balloon/final instalment is generally not subject to GST (it is part of the financed amount).

Finance lease

• Lessor owns the equipment and charges GST on each rental.
• You claim GST credits on each rental as it is paid (accrual reporters can claim on tax invoice date; cash reporters claim on payment).
• Residual value at term end includes GST; claimable when paid if used for creditable purposes.

Understand finance lease GST

Operating lease

• GST applies to each rental payment; you claim progressively.
• End-of-term options (extend, return, upgrade) do not usually involve a residual payment by you, but check your contract.

GST timing: cash vs accrual BAS

• Cash basis: You generally claim input tax credits when you pay for the supply. Under chattel mortgage/hire purchase, the supplier is paid in full at settlement, so the full GST credit is typically claimable at that time. Under leases, you claim credits on each rental as you pay it, and on the residual (finance lease) when paid.
• Accrual basis: You can usually claim based on when you receive the tax invoice (or when the supply is made), provided you will pay for it. For leases, claim as per the tax invoices for rentals; for chattel/hire purchase, claim upfront on the asset tax invoice.

Check GST timing for your BAS

Worked examples

Example 1: Excavator via chattel mortgage

• Price (ex GST): $200,000
• GST: $20,000
• Total supplier invoice: $220,000
• GST treatment: Claim $20,000 on the next BAS (subject to creditable use). No GST on repayments (principal + interest). Establishment fee may include GST.

Example 2: Loader via finance lease

• Monthly rental: $4,400 (includes $400 GST)
• GST treatment: Claim $400 input tax credit each month as paid or invoiced (depending on BAS method).
• End-of-term residual: $66,000 (incl. $6,000 GST) → claim $6,000 when paid if continuing creditable use.

Example 3: Imported used crane

• GST may be payable on the taxable importation at customs.
• Claim the customs GST on your BAS if the import is creditable and you hold the import declaration.
• Finance structure then follows the usual GST rules noted above.

Special cases and nuances

Used equipment and private sellers

• If buying from a GST-registered supplier issuing a tax invoice, you can usually claim the GST shown.
• If the margin scheme is used or you buy from a private seller (no GST on the sale), you cannot claim GST credits.

Mixed business/private use

• Only claim GST credits for the creditable (business) use percentage. Keep a reasonable basis for your apportionment.

Deposits, trade-ins and balloons/residuals

• Deposits: Claim GST on the deposit if GST is included and a tax invoice is held.
• Trade-ins: The trade-in may be a taxable supply—ensure you don’t double count GST on the net figure.
• Chattel mortgage/hire purchase balloons: generally no GST on the balloon (it’s a principal repayment).
• Finance lease residuals: GST applies to the residual; you may claim at payment if creditable.

Fees, insurance and extras

• Lender/broker establishment and monthly account fees may include GST (check the tax invoice).
• PPSR and some government charges are GST-free.
• Equipment insurance premiums generally include GST and stamp duty (stamp duty is not a GST credit).

Clarify a tricky GST scenario

Approval and documentation

Lenders focus on the asset, your trading strength and the chosen structure. Clean documentation helps both your approval and your GST position.

• Equipment quote or supplier tax invoice (showing GST treatment)
• ABN and GST registration details
• Recent BAS and bank statements (to support trading)
• Financials or low-doc alternatives (depending on product and amount)
• Import documents if buying from overseas, or trade-in paperwork if applicable

Ask what documents you’ll need

Common GST mistakes to avoid

• Claiming GST when you are not GST-registered or the use is not creditable
• Not apportioning for private or input-taxed use
• Assuming you can claim GST on a margin scheme or private sale invoice
• Confusing lease residuals (GST applies) with chattel balloons (no GST)
• Forgetting GST on taxable importations, or not holding required documents
• Double counting GST when trade-ins are involved
