Overview: why GST treatment matters for dentists
Getting GST right on dental equipment finance affects cash flow, BAS timing and total cost. While most dental services are GST‑free, practices can generally still claim input tax credits (ITCs) on business purchases like equipment used in the practice. The way and the timing you claim depends on the finance product you choose.
- GST rate in Australia is 10%.
- Valid tax invoices are required to claim credits.
- Your BAS method (cash or accrual) can affect timing but not the overall entitlement.

How GST works by finance type
The core GST rules for dental equipment differ across chattel mortgage, hire purchase, finance lease and operating lease. Here is the high‑level treatment most practices encounter.
Chattel Mortgage (asset loan)
- GST is generally charged on the equipment purchase price by the supplier at settlement.
- If you are registered for GST and hold a valid tax invoice, you can usually claim the full GST credit in the BAS period you receive the invoice (subject to business‑use percentage).
- Loan repayments (principal) and interest are not subject to GST.
- Financier fees (e.g., establishment or documentation fees) usually include GST and are creditable.
- Balloon amounts are repayments of principal, so no GST applies to the balloon itself.
Hire Purchase
- For agreements entered into on or after 1 July 2012, GST is generally calculated on the asset’s full taxable value at commencement.
- Eligible GST‑registered practices can usually claim the full GST credit upfront in the BAS for the period they receive a valid tax invoice, even though payments occur over time.
- The interest component is not subject to GST; applicable fees typically include GST.
Finance Lease
- Lease rentals generally attract GST on each repayment because leasing is a taxable supply by the lessor.
- You typically claim GST credits progressively on the GST included in each lease payment.
- Upfront and ongoing lease fees usually include GST and are creditable.
- If you purchase the asset at the end of the term, GST is payable on the residual purchase price and is claimable with a valid tax invoice.
Operating Lease
- Similar GST treatment to a finance lease: GST applies to each rental and to most fees.
- No residual purchase unless you elect to buy the asset at market value; GST would then apply to that purchase price.

Cash flow examples for a dental practice
Example 1: Chattel mortgage
Purchase a CBCT imaging unit for $110,000 inc GST ($100,000 + $10,000 GST). You finance 100% under a chattel mortgage.
- Supplier charges $10,000 GST on the invoice.
- You can generally claim a $10,000 GST credit in your next BAS (with a valid tax invoice and business use).
- Your repayments are not subject to GST (interest is not subject to GST; principal repayments are GST‑free).
Example 2: Finance lease
Lease the same $110,000 unit.
- Each lease rental includes GST. You claim credits progressively on each BAS.
- If you exercise a purchase option at the end, GST applies to the residual purchase price and is then claimable.
These are generalised examples. GST outcomes depend on your agreement, invoices and usage. Always confirm with your accountant or tax adviser.
Key considerations specific to dental equipment
- GST registration and BAS method: Both cash and accrual reporters can generally claim the same total GST; timing may differ.
- Business use: Claim credits only to the extent of business use. Most practice equipment is 100% business use.
- Dental services are GST‑free: Your services being GST‑free does not usually prevent ITCs on practice equipment used to make those supplies.
- Used equipment: If purchased from an unregistered private seller, no GST is charged and no credit is available. From a registered supplier, GST is typically on the invoice and claimable.
- Imports: GST on importation is commonly creditable when you are the importer of record and hold required documents (e.g., import declaration).
- Trade‑ins: GST is determined by the tax invoice from the supplier/dealer; your credit is based on the GST shown on the consideration payable.
- Fees and charges: Financier fees generally include GST (creditable); interest does not. Government charges (e.g., PPSR fees) can have separate treatment.
- Balloon/residual: No GST on a chattel mortgage balloon. GST applies to a lease residual when you buy the asset.
- Instant asset write‑off vs GST: Instant asset write‑off is an income tax deduction and separate from GST credits.
Approval and documentation: what lenders and the BAS expect
- Signed finance agreement showing the structure (chattel mortgage, hire purchase, lease).
- Supplier tax invoice with GST clearly itemised (or import documentation if applicable).
- Lease schedule (for leases) showing GST on rentals and any fees.
- Business details, ABN and GST registration status.
- Bank statements and financials per lender requirements.
Solid documentation reduces friction with both the lender and your BAS claims.
BAS claiming steps (at a glance)
- Confirm your GST registration and BAS method (cash or accrual).
- Choose a finance type and obtain the finance agreement.
- Secure a valid tax invoice from the supplier (or lease schedule for rentals, or import documents).
- Record GST on purchase (chattel/hire purchase) or on each rental (leases).
- Claim ITCs in the BAS period corresponding to your documentation and method.
- Keep records for audit: invoices, agreements, statements and usage notes.

Frequently asked questions
What is dental equipment finance GST treatment?
It refers to how GST is applied and claimed when you finance practice assets (e.g., chairs, imaging, sterilisers). Chattel mortgages and hire purchase usually allow an upfront GST credit on the asset invoice, while leases spread GST over each rental and apply GST to any residual purchase.
Can dental practices claim GST even though services are GST‑free?
Yes. Dental services are generally GST‑free, but that does not usually prevent you from claiming input tax credits on creditable acquisitions like practice equipment, subject to business use and documentation.
When do I claim GST on a chattel mortgage?
Typically in the BAS period you receive a valid supplier tax invoice for the equipment. Repayments and interest are not subject to GST.
How does GST work on a finance lease residual?
If you buy the asset at the end of the lease, GST applies to the residual purchase price. You can then claim that GST (subject to eligibility and a valid tax invoice).
What if I buy used equipment from a private seller?
If the seller is not registered for GST and no GST is charged, you cannot claim a GST credit. If you buy from a GST‑registered supplier who charges GST, you can generally claim it with a valid tax invoice.
Do deposits, fees and balloons have GST?
Deposits form part of the purchase consideration (GST is based on the taxable sale). Financier fees often include GST and are creditable. A chattel mortgage balloon is a principal repayment (no GST); a lease residual purchase is a taxable sale (GST applies).
Does my BAS method change the GST I can claim?
It usually changes the timing, not the total entitlement. Cash vs accrual reporting can alter when the credit appears in your BAS, provided you have valid documentation.
Final takeaway
For dental equipment finance in Australia, chattel mortgage and hire purchase often maximise upfront GST credits, while leases spread claims across rentals and add GST to any residual purchase. The “best” approach depends on your cash flow, BAS method, and end‑of‑term plans.
