Overview
If you’re GST-registered and buying an excavator for business use, GST can usually be claimed as an input tax credit. The timing and amount you can claim depends on the finance product you use and how the excavator is used in your business.
- GST applies to the purchase if the seller charges GST (e.g., dealer). No GST credit if you buy from a private seller.
- Chattel mortgage and hire purchase generally allow an upfront GST claim on the full taxable price.
- Finance and operating leases spread GST across each rental and, for finance leases, the residual.
- You must apportion for any private or input‑taxed use and keep valid tax invoices.
GST by finance type
The GST impact of excavator finance mainly depends on whether you acquire the asset upfront (chattel mortgage or hire purchase) or pay to use it over time (leases).
Chattel mortgage (equipment loan)
- GST on purchase: Usually claimable in full on your next BAS (to the extent of business use) once you hold a valid tax invoice.
- Repayments: Principal and interest do not attract GST. Establishment fees and monthly account fees typically do and are claimable.
- Balloon: No additional GST at balloon payment; GST was addressed upfront on the purchase price.
Hire purchase
- GST on purchase: For agreements entered into after 1 July 2012, GST is calculated on the taxable price of the excavator and is generally claimable upfront (subject to business use and a valid tax invoice).
- Repayments: Interest/credit charges are not subject to GST; fees often are.
- Final amount: No extra GST when finalising the hire purchase principal; GST was dealt with at commencement.
Finance lease
- GST on rentals: GST applies to each lease rental; you claim the GST for each tax period when the rental is paid/invoiced (depending on your BAS method).
- Residual: GST applies when you pay the residual/option to purchase.
- No upfront GST claim on the full asset price under a finance lease.
Operating lease
- GST on rentals: GST is included in each rental and claimable per period.
- End-of-term: Typically no residual ownership. Any fees/charges at end may include GST.

Eligibility, BAS timing and apportionment
- Registration: You must be GST‑registered and acquire the excavator for a creditable (business) purpose.
- Tax invoice: Keep a valid tax invoice from the supplier and any finance documentation that shows fees with GST.
- BAS method:
- Cash basis: Claim the input tax credit when you have a tax invoice and have paid, per BAS rules.
- Accrual basis: Claim when you hold a valid tax invoice (even if unpaid), subject to ATO rules.
- Business vs private use: Claim only the percentage related to business use. Mixed use must be apportioned and reviewed annually if usage changes.
Worked examples
Example (dealer purchase, price $220,000 including GST):
- GST component = $20,000.
- Chattel mortgage or hire purchase: Generally claim up to $20,000 on your next BAS (adjusted for business-use %). Repayments are not subject to GST; fees typically are.
- Finance lease: Claim the GST included in each rental as you go; GST is also payable and claimable on the residual at end of term.
Note: Figures are illustrative. Confirm your exact treatment with your accountant or the ATO based on your BAS method and usage.
Common scenarios for excavators
- Used excavator from a dealer: If GST is charged, you can generally claim it (subject to business use). Keep the dealer invoice.
- Used excavator from a private seller: No GST charged, so no input tax credit available.
- Trade‑in: If registered for GST, you usually charge GST on the trade‑in sale amount. The new purchase GST claim is independent of the trade‑in.
- Attachments and buckets: If purchased with the machine and invoiced with GST, claimable like the main asset.
- Imports: GST is generally payable on import; eligible businesses may use the ATO’s Deferred GST Scheme to manage cash flow.
- Government charges and insurance: Stamp duty is not subject to GST. Insurance premiums typically include GST and may be claimable.
Approval and documentation
Lenders will assess the deal based on the asset, your trading profile and the chosen product. For smooth GST claiming and a clean approval, have:
- Supplier quote or tax invoice showing GST treatment.
- Business ABN and GST registration status.
- Details of any trade‑ins, deposits, or imports (including import declarations if applicable).
- Bank statements, financials or alternative income verification (varies by lender and product).
- Proof of insurance and any asset serials/VINs as required.
Mistakes to avoid
- Claiming full GST when there’s private or input‑taxed use. Always apportion.
- Assuming repayments include GST under a chattel mortgage or hire purchase. They generally don’t—check fees for GST.
- Missing GST on finance lease residuals. The residual usually attracts GST.
- Expecting a GST credit on a private‑to‑business purchase where no GST was charged.
- Claiming without a valid tax invoice or correct BAS timing for your accounting method.
Tip: Pair your product choice with your cash‑flow goals. If an upfront GST credit helps working capital, chattel mortgage or hire purchase may align. If you prefer spreading GST, consider a lease.

Frequently asked questions
What is excavator finance GST treatment in Australia?
It’s how GST is applied and claimed when you buy or lease an excavator for business use. Upfront ownership products (chattel mortgage, hire purchase) generally allow an upfront GST claim on the taxable price, while leases spread GST across rentals (and the residual for finance leases).
Can I claim the full GST upfront on an excavator?
Typically yes with a chattel mortgage or hire purchase, provided you’re GST‑registered, have a valid tax invoice, and the excavator is used for a creditable (business) purpose. Apportion for any private or input‑taxed use.
How does GST work on a finance lease for an excavator?
GST applies to each lease rental, which you claim period by period. If you purchase the excavator at the end of term, the residual payment generally includes GST, which is claimable then.
Is there GST on excavator loan repayments?
For chattel mortgage and hire purchase, repayments are generally not subject to GST. Establishment and account fees usually are and can be claimed. For leases, rentals include GST.
Does the balloon or residual have GST?
Balloon (chattel mortgage/hire purchase): No additional GST—GST was addressed upfront. Residual (finance lease): GST applies and is claimable when paid.
Can I claim GST on a used excavator?
Yes if the seller charges GST (e.g., a dealer). If you buy from a private seller who does not charge GST, there’s no input tax credit to claim.
How are trade‑ins treated for GST?
If you are GST‑registered, you usually account for GST on the trade‑in sale amount. The GST claim on the new excavator purchase is based on the supplier’s invoice and your business‑use percentage.
What about imported excavators?
GST is generally payable on import. If eligible, the ATO’s Deferred GST Scheme can help cash flow. Keep import and customs documentation for your BAS and lender.
Does my BAS method change when I claim?
Yes. On cash basis, you typically claim when you have a valid tax invoice and have paid. On accrual, you generally claim when you hold a valid tax invoice, even if unpaid. Confirm treatment with your accountant.
