GST on a commercial property purchase in Australia depends on the supplier, the property and the contract. A taxable sale may include goods and services tax (GST), while a qualifying going-concern sale may be GST-free. A margin-scheme sale has a different calculation and generally does not give the buyer a GST credit for the property. Have your accountant and commercial solicitor confirm the GST clause, evidence and cash-flow treatment before you sign.
Picture this: you find an office building in Sydney or an industrial unit in Melbourne advertised at a price "plus GST". You are wondering whether that GST amount is genuinely payable upfront, whether you can recover it, and whether the going-concern wording in the draft contract actually protects you. Those are exactly the right questions.
The problem is that the answer is not the same for every commercial asset. The goods and services tax treatment of a commercial property purchase depends on the vendor's GST registration status, the nature of the supply, the property's use and the precise wording of the contract. Yield, capitalisation rate and WALE are separate considerations entirely; they do not determine GST treatment.
This article provides a due-diligence framework for Australian commercial investors, business owners and SMSF trustees. It is general information only and cannot determine the GST treatment of your specific transaction. Before signing any commercial property contract, obtain transaction-specific advice from your accountant and a commercial solicitor.
This article is published by Buyers Agency Australia, which provides buyer-side property advisory services.
Do I pay GST when I buy a commercial property in Australia?
Commercial property is not governed by a single automatic rule. According to the Australian Taxation Office (ATO), a supply attracts GST when the supplier is registered or required to be registered for GST, the supply is made in the course of an enterprise, and the supply has an Australian connection. The standard GST rate is 10% of the GST-exclusive price, but whether that applies to a specific commercial acquisition depends on the facts.
Three treatment categories matter most to buyers:
| Treatment | What it means for the buyer | Key check |
|---|---|---|
| Taxable sale | GST may be added to the purchase price. The buyer may be entitled to an input tax credit if ATO requirements are met. | Confirm vendor GST registration and contract price wording. |
| Qualifying GST-free going-concern sale | A supply meeting all statutory conditions may be GST-free. No GST appears in the price, and no credit is claimed. | Confirm conditions are met, both parties are registered, and the contract documents the treatment. |
| Sale under the margin scheme | GST is calculated on the vendor's margin, not the full price. The buyer cannot claim a GST credit for the property acquisition. | Confirm written agreement exists before settlement and review the credit consequence with your accountant. |
The key insight for buyers: the listing price and even a verbal representation from the selling agent are not sufficient. The contract is the controlling document.
What does "plus GST" mean in a commercial property contract?
When a commercial property is advertised or contracted at a price "plus GST", that wording typically signals that the stated price is GST-exclusive, meaning GST is added on top. On a $2 million asset, "plus GST" could mean the buyer funds $2.2 million (illustrative only; this is not a tax calculation for any specific transaction). That difference affects finance approval, deposit calculations and settlement funding.
Critically, the listing price is not the contract. The executed contract of sale and its GST clause are the authoritative documents. A listing may say "plus GST" while the vendor proposes going-concern treatment in the contract, or vice versa. Neither outcome can be assumed without reviewing the contract, identifying the vendor entity, and obtaining accountant and solicitor confirmation before signing.
Pre-signing contract checklist:
- Is the price stated as GST-inclusive, plus GST, or GST-free?
- Does the contract identify the intended GST treatment?
- Is the vendor entity identified and is its GST registration status verified?
- Does the contract refer to going-concern or margin-scheme treatment?
- Are lease documents and lease assignment terms included where relevant?
- Has the accountant reviewed the proposed treatment before you sign?
None of these questions can be answered by the listing alone.
What evidence should a buyer request before signing?
- Proposed sale contract and GST clause: confirms the treatment and price basis.
- Vendor entity details and GST registration evidence: verifies the supplier's status via ABN Lookup or vendor disclosure.
- Executed lease and rent ledger: needed to assess whether going-concern conditions may be satisfied.
- Lease assignment or novation terms: confirms whether the leasing enterprise and tenant rights transfer with the property.
- Any going-concern or margin-scheme written agreement: must exist before settlement to be effective.
- Accountant and solicitor review confirmation: their sign-off before exchange protects your cash-flow and credit position.
Each document answers a specific question your advisers need answered before the transaction can be assessed safely.
Can I claim GST back on a commercial property purchase?
Maybe, but not automatically. A GST input tax credit is not a guaranteed consequence of buying a commercial property with GST in the price. According to ATO creditable-acquisition guidance, four conditions must each be satisfied:
- Buyer entity and GST status: the purchaser must be registered or required to be registered for GST.
- Creditable purpose: the acquisition must be for the purpose of making taxable supplies or GST-free supplies, not for input-taxed or private use.
- Contract treatment: the supply must be a taxable supply, not a going-concern or margin-scheme acquisition.
- Evidence: a valid tax invoice from the vendor must be held before the credit is claimed on the business activity statement (BAS).
A margin-scheme acquisition is not a creditable acquisition for the property. When the margin scheme applies, the purchaser cannot claim a GST credit for the property cost, regardless of the buyer's GST registration status. This is one of the most consequential points buyers overlook when reviewing a commercial property contract plus GST or margin-scheme wording.
Do not rely on a BAS credit position that has not been confirmed by your accountant against the actual contract and supply evidence.
What is a GST-free going concern in a commercial property sale?
A qualifying supply of a going concern may be GST-free under section 38-325 of the GST Act, as clarified in ATO ruling GSTR 2002/5. For a leased commercial property, the enterprise typically being supplied is the leasing enterprise: the vendor transfers the lease, the tenant in occupation and all assets necessary for the enterprise to continue.
The treatment is not automatic. Every condition must be satisfied:
| Condition | What is required |
|---|---|
| Enterprise being carried on before settlement | The leasing enterprise must be active, not wound down or vacant. |
| Necessary assets and rights supplied | Lease, assignments, management agreements and associated rights must transfer. |
| Enterprise carried on until the day of supply | The vendor must not cease the enterprise before settlement. |
| Both parties agree in writing | The contract must document the going-concern treatment. |
| Both parties registered for GST | Purchaser must be registered or required to be registered. |
A tenanted industrial property or occupied retail premises can potentially qualify, but the facts, lease continuity, parties and contract wording all matter. A partially vacant building may also qualify in certain circumstances, but specialist advice is required. Do not treat an ATO private ruling issued for another taxpayer as a universal precedent for your transaction.
How does the margin scheme change a commercial property purchase?
The margin scheme is a method for calculating GST on an eligible taxable real-property supply. Instead of GST applying to the full sale price, the vendor calculates GST on their margin (broadly, the sale price minus an eligible cost base). A written agreement between vendor and purchaser is required before settlement for the scheme to apply.
The buyer's key consequence:
| Contract treatment | GST in price | Buyer's GST-credit position | Evidence to confirm |
|---|---|---|---|
| Taxable sale (full GST) | Yes, 1/11th of purchase price | May be claimable if all ITC conditions met | Tax invoice, registration, creditable purpose |
| Going-concern sale | No GST | No credit claimed | Contract, lease, written agreement |
| Margin-scheme sale | Reduced GST (on margin) | No GST credit for the property acquisition | Written agreement before settlement, contract |
A common misconception is that the margin scheme is a buyer benefit. It is primarily a vendor calculation method. The purchaser generally cannot claim a GST credit for the property cost when the margin scheme applies. Any suggestion that the margin scheme saves the buyer GST should be reviewed carefully with a tax adviser.
Which GST treatment applies in common commercial property scenarios?
The scenario table below maps common acquisition situations to the GST question the buyer must send to their accountant and solicitor. It does not declare the final tax outcome for any real transaction.
| Scenario | GST question to ask | Evidence to check | Adviser to confirm with |
|---|---|---|---|
| Office building sold with an existing commercial lease | Is the leasing enterprise being supplied as a going concern? | Executed lease, assignment terms, vendor GST registration, contract clause | Accountant and commercial solicitor |
| Retail property where the contract proposes going-concern treatment | Are all five going-concern conditions met in the contract and transaction facts? | Written going-concern agreement, lease continuity, vendor conduct before settlement | Commercial solicitor and accountant |
| Industrial property advertised at a price plus GST | Is the price GST-exclusive? Is the supply taxable? Is an input tax credit available? | Contract wording, vendor GST status, tax invoice | Accountant before signing |
| Commercial property contract referring to the margin scheme | Is a written margin-scheme agreement in place before settlement? Can the buyer claim a GST credit? | Written agreement, contract | Accountant and solicitor |
| Property acquired by a GST-registered business for business use | Is the acquisition for a creditable purpose? Is the supply taxable? | Tax invoice, registration, use of property | Accountant |
| Property acquired through a trust, company or SMSF structure | Which entity is the purchaser? Is it GST-registered? Does the structure affect creditable purpose? | Governing documents, entity GST status, SMSF trustee rules where applicable | SMSF specialist and accountant |
For SMSF structures and complex entity arrangements, specialist advice is essential before any offer is made or contract is signed. This table is a starting point for your professional review, not a conclusion.
What should I check before making an offer and before settlement?
GST review sits inside a broader commercial property due diligence checklist. The two critical windows are before signing and before settlement.
Stage 1: Before making an offer or signing
- Confirm whether the advertised price is GST-inclusive or GST-exclusive.
- Request the proposed contract and identify the GST clause.
- Identify the supplier entity and verify its GST registration via ABN Lookup.
- Ask whether going-concern or margin-scheme treatment is proposed.
- Allow your accountant and solicitor to review all documents before exchange.
- Confirm finance and cash reserves based on the contract amount, not the headline listing.
Stage 2: Before settlement
- Confirm any required written agreement or notification is in place (going concern or margin scheme).
- Reconcile the settlement statement with the executed contract.
- Confirm lease assignment and tenant documentation where relevant.
- Confirm BAS and record-keeping requirements with your accountant.
- Ask your conveyancer to confirm whether any withholding obligation applies. Note that the ATO's GST-at-settlement withholding rules are primarily directed at new residential premises and potential residential land; do not assume they apply automatically to an ordinary commercial property purchase without conveyancer confirmation.
GST treatment confirmed after settlement is too late to be useful. Confirm it before the offer.
How Buyers Agency Australia supports the commercial buying process
Buyers Agency Australia works on the buyer's side throughout the commercial acquisition process, from defining the initial brief and sourcing suitable office, retail and industrial assets through to coordinating commercial due diligence, supporting negotiation and managing the buyer-side process through settlement.
Dragan Dimovski, a property expert with more than 20 years of experience, leads a process that distinguishes the buyer's agent role from the accountant, solicitor, valuer, finance broker and building specialists. Each professional has a defined role. Commercial property acquisition support from Buyers Agency Australia means the buyer does not have to manage those moving parts alone.
Buyers Agency Australia does not determine GST treatment and does not replace the buyer's accountant or solicitor. What the team does is help coordinate the sequence so that every specialist, including the accountant reviewing the GST clause and the solicitor reviewing the contract, receives the information they need and is engaged at the right time.
If you are assessing a commercial acquisition and want experienced buyer-side support coordinating the process, book a free strategy session to discuss your brief.
When a commercial buyers agent is not the right fit
A self-directed buyer with a defined acquisition strategy, trusted relationships with commercial selling agents, sufficient time to manage the search and due diligence process, and an established legal, tax, finance and valuation team may prefer to manage the commercial acquisition independently. That is a reasonable choice. The decision should be based on the buyer's genuine capacity to coordinate each stage of the process, not on cost alone.
Frequently asked questions about GST on commercial property in Australia
1. Do you pay GST when buying commercial property in Australia?
You may, depending on the supplier's registration, the nature of the supply and the contract treatment. Taxable, GST-free going-concern and margin-scheme outcomes are all possible and each must be confirmed by your advisers.
2. What does plus GST mean on a commercial property contract?
It generally means the stated price does not include the GST amount. The contract must be reviewed to confirm the intended treatment, price basis and the vendor's GST status.
3. Can I claim GST back on a commercial property purchase?
You may be entitled to an input tax credit if the ATO requirements are met: GST registration, creditable purpose, a taxable supply and a valid tax invoice. Your accountant must confirm the position.
4. Can I claim GST on a commercial property bought under the margin scheme?
Generally, no GST credit is available for the property acquisition when the margin scheme applies. The scheme changes the vendor's calculation, not the buyer's credit entitlement.
5. Is a tenanted commercial property automatically a going concern?
No. Tenancy alone does not establish going-concern treatment. The enterprise, necessary assets, lease continuity, written agreement and contract wording must all align.
6. What documents should I give my accountant before signing?
Provide the proposed contract, price and GST clause details, executed lease documents, any proposed going-concern or margin-scheme agreement, and vendor entity information.
7. Does GST apply to office, retail and industrial property in the same way?
The same GST framework applies across commercial asset classes, but the transaction facts, use of the property, lease structure and contract treatment still need to be reviewed individually.
8. Does GST at settlement apply to a commercial property purchase?
Do not assume it does. Ask your conveyancer to confirm whether a withholding obligation applies. The ATO's withholding rules focus primarily on new residential premises and potential residential land.
9. Can a buyers agent confirm the GST treatment of a property?
A buyers agent can help coordinate the review process, but the buyer's accountant and solicitor should confirm the tax and contract treatment. Buyers Agency Australia's role is buyer-side acquisition coordination, not tax or legal advice.
Final checklist: confirm GST before signing, not after settlement
The practical decision point is before signing, not after funds are committed. Review this before any commercial offer is made:
- Confirm whether the contract price is GST-inclusive, GST-exclusive or GST-free.
- Identify the vendor entity and verify GST registration.
- Understand the proposed treatment: taxable, going concern or margin scheme.
- Provide the contract and lease documents to your accountant and commercial solicitor for review.
- Confirm your cash-flow and finance position based on the contract amount.
- Before settlement, confirm any required written agreements and ask your conveyancer about applicable withholding obligations.
The questions belong with your accountant (GST registration, creditable purpose, BAS treatment), your commercial solicitor (contract wording, going-concern conditions, margin-scheme agreement), and your conveyancer (settlement statement, withholding confirmation).
