GST on Property Sales: When It Applies and When It Doesn’t

Introduction: Why GST on Property Sales Matters

Property transactions are among the most significant financial events for any individual or business. In Australia, the Goods and Services Tax (GST) can add 10% to the cost of a property sale, but the rules are far from straightforward. Whether you are a sole trader selling a commercial unit, a small business subdividing land, or an investor offloading a rental property, understanding when GST applies—and when it doesn’t—can mean the difference between a profitable sale and an unexpected tax bill.

This pillar article provides a comprehensive, practical guide to GST on property sales. We’ll break down the core principles, explore the most common scenarios, and highlight the traps that catch even experienced property owners. By the end, you’ll have a clear framework to determine your GST obligations and the confidence to plan your next transaction.

1. The Basic Rule: When GST Applies to Property Sales

Under the A New Tax System (Goods and Services Tax) Act 1999, GST is generally payable on the supply of real property unless a specific exemption or concession applies. However, the type of property and its use determine the GST treatment.

Taxable Supplies of Real Property

A sale of property is a taxable supply if it is made in the course of an enterprise, the seller is registered for GST, and the sale is not input-taxed or GST-free. The most common taxable property sales include:

• New residential premises (including new homes, apartments, and units) sold by a developer or builder.
• Commercial property (e.g., offices, retail shops, warehouses) sold by a GST-registered business.
• Vacant land that is not residential land (e.g., commercial or industrial land).
• Property sold after a significant renovation that creates new residential premises.

When GST applies, the seller must include GST in the sale price (unless the margin scheme is used) and remit it to the ATO. The buyer may be able to claim an input tax credit if they are registered for GST and the purchase is for their enterprise.

Expert Tip: Always check if the property is ‘new residential premises’—this is the most common trigger for GST. A property is new if it has not been sold as residential premises before, is built to replace demolished premises, or is a substantial renovation of an existing building.

2. Input-Taxed Sales: When GST Does Not Apply

Some property sales are input-taxed, meaning no GST is charged on the sale, but the seller cannot claim input tax credits for related expenses. The most significant input-taxed supply is the sale of existing residential premises.

Existing Residential Premises

If you sell a residential property that has been previously occupied or rented (i.e., not new), the sale is input-taxed. This applies to:

• Established houses, units, and apartments.
• Properties that have been rented out for residential accommodation.
• Properties that have been used as a principal place of residence (though private sales may not be in the course of an enterprise).

Because the sale is input-taxed, you do not charge GST to the buyer, and you cannot claim GST credits on costs like agent commissions, legal fees, or repairs. This is a critical distinction for property investors.

Residential Rent and Leases

Similarly, residential rent is input-taxed. If you rent out a residential property, the rental income is not subject to GST, and you cannot claim input tax credits on expenses related to that rental (e.g., maintenance, property management fees).

Warning: If you sell a property that was previously used for both residential and commercial purposes (e.g., a shop with a residence above), the sale may be partly taxable and partly input-taxed. You must apportion the sale price based on the use.

3. The Margin Scheme: Reducing GST on Property Sales

The margin scheme is a special method for calculating GST on property sales. Instead of paying GST on the full sale price, you pay GST on the profit margin—the difference between the sale price and the original cost of the property (or its value at a certain date). This can significantly reduce the GST liability.

Who Can Use the Margin Scheme?

The margin scheme can be used for sales of:

• New residential premises (other than those sold through a taxable supply that is not new).
• Commercial property (if the seller acquired it before 1 July 2000 or through certain transactions).
• Vacant land (in some cases).

However, the margin scheme cannot be used if the property was acquired with an input tax credit entitlement (i.e., you claimed GST credits on the purchase).

How to Calculate the Margin

The margin is generally the difference between the sale price and the cost of the property to the seller. If the property was acquired before 1 July 2000, the margin is based on the property’s value on that date. The GST is then 1/11th of the margin.

Using the margin scheme can be complex, and you must notify the buyer in writing if you use it. The buyer cannot claim an input tax credit for the GST component if the margin scheme is used.

Expert Tip: The margin scheme is optional. You must elect to use it in your GST return and provide the buyer with a statement. Seek advice from a tax professional to determine if it’s beneficial in your situation.

4. New Residential Premises vs. Existing Residential Premises

The distinction between new and existing residential premises is central to GST on property sales. The ATO defines new residential premises as:

• Premises that have not been sold as residential premises before (e.g., a newly built home).
• Premises created through substantial renovations (where the building is stripped back to the framework and rebuilt).
• Premises built to replace demolished premises on the same land.

If a property is new, its sale is generally taxable (unless the margin scheme applies). If it is existing, the sale is input-taxed.

Substantial Renovations

A renovation is ‘substantial’ if it involves the removal or replacement of all or substantially all of the building’s internal and external load-bearing structures. Cosmetic updates like new kitchens or bathrooms do not qualify.

Practical Example

Imagine you buy an old house, renovate it extensively (replacing the roof, floors, and walls), and sell it. The ATO may consider the property ‘new residential premises’ because it was substantially renovated. You would then need to charge GST on the sale, unless you use the margin scheme. This is a common trap for property flippers.

Warning: If you are a property developer or flipper, you are likely carrying on an enterprise and must be registered for GST. Even if you sell only one property, the ATO may view it as a business activity.

5. Commercial Property Sales: GST and Going Concern Exemption

Commercial property sales are generally taxable supplies, meaning GST applies. However, there is a significant exemption: the going concern exemption.

What is a Going Concern?

A supply of a going concern is the sale of an enterprise (or a part of an enterprise) that is capable of continuing as a going concern. For property, this typically means selling a commercial property that is leased to a tenant and the lease is transferred to the buyer. The seller must supply everything necessary for the buyer to continue the business.

Conditions for the Exemption

To be GST-free as a going concern, all of the following must apply:

1. The supply is of a going concern (i.e., the property is leased and the lease is assigned).
2. The buyer is registered for GST (or will be before the supply).
3. Both parties agree in writing that the supply is a going concern.
4. The seller carries on the enterprise until the day of supply.

If these conditions are met, the sale is GST-free, meaning no GST is charged, and the buyer cannot claim an input tax credit (because there is no GST). This is often beneficial for both parties.

Example

A small business owner sells a commercial warehouse that is leased to a logistics company. The lease is transferred to the buyer, and both parties sign a going concern agreement. The sale is GST-free, saving the buyer 10% in upfront costs.

Expert Tip: The going concern exemption is not automatic. You must have a written agreement and meet all conditions. If the lease is terminated before settlement, the exemption may be lost.

6. Subdividing Land and GST Implications

Subdividing land and selling the lots can trigger GST, depending on the circumstances. If you are a property developer or carry on an enterprise, the sale of subdivided lots is generally taxable. However, if you are an individual selling your own land, the GST treatment may differ.

When GST Applies to Subdivided Land

If you subdivide land and sell the lots in the course of an enterprise (e.g., you are a developer), GST applies to each sale. You must be registered for GST if your turnover exceeds the threshold (currently $75,000).

If you are not in an enterprise, the sale of your own land may be a private transaction and not subject to GST. However, if you subdivide and sell multiple lots, the ATO may consider you to be carrying on an enterprise, especially if you make a profit.

Margin Scheme for Subdivided Land

The margin scheme can be used for subdivided land if you acquired the land before 1 July 2000 or if you meet other criteria. The margin is calculated on the difference between the sale price and the original cost of the land (or its value on 1 July 2000).

Example

A farmer subdivides a portion of their land into residential lots. If the farmer is not in the business of property development, the sale of the lots may be private and GST-free. However, if the farmer subdivides and sells several lots over time, the ATO may deem it an enterprise, and GST would apply.

Warning: The ATO has specific rules for ‘land subdivided for sale’—even if you are not a developer, you may be liable for GST if you are ‘carrying on an enterprise’ with the intention of profit. Seek advice before subdividing.

7. Property Development and GST: The Developer’s Perspective

Property developers face unique GST challenges. From purchasing land to selling completed properties, every stage has GST implications.

Purchasing Land

When a developer buys land, they may be able to claim input tax credits on the purchase if the land is used for a taxable supply (e.g., building new residential premises for sale). However, if the land is used for input-taxed supplies (e.g., residential rent), no credit is available.

Construction Costs

Developers can claim GST credits on construction costs, materials, and professional fees, provided the development is for taxable sales. This is a significant cash flow benefit.

Selling New Residential Premises

Sales of new residential premises are taxable, and developers must charge GST. They can use the margin scheme to reduce the GST payable, but they must be careful to meet the requirements.

GST on Deposits and Progress Payments

For off-the-plan sales, GST is generally payable at settlement, not on the deposit. However, if the developer receives progress payments, GST may be due on each payment.

Expert Tip: Developers should consider using the ‘margin scheme’ for new residential premises to reduce GST. However, if the buyer is a GST-registered business that intends to rent the property, they may prefer a taxable supply to claim input tax credits. Negotiate the price accordingly.

8. GST on Property Sales by Non-Residents and Foreign Investors

Non-residents selling Australian property are subject to GST, but there are additional rules and withholding obligations.

Non-Resident Sellers

If a non-resident sells Australian real property, they must be registered for GST if the sale is a taxable supply. This applies even if they are not carrying on an enterprise in Australia, as the sale of property is considered a taxable supply if the property is in Australia.

Foreign Resident Capital Gains Withholding

Since 2016, buyers of Australian property must withhold 12.5% of the purchase price and remit it to the ATO if the seller is a foreign resident, unless the seller obtains a clearance certificate. This is not GST, but it affects cash flow.

GST on New Residential Premises Sold by Foreign Developers

Foreign developers must also charge GST on new residential premises. They may be eligible for the margin scheme, but they must meet the same conditions as Australian residents.

Warning: Non-residents may be required to register for GST even if their turnover is below the threshold, because the sale of property is a taxable supply that is not input-taxed. Always check your obligations.

Common GST Mistakes to Avoid

Property sellers often make errors that lead to penalties or missed opportunities. Here are the most frequent mistakes:

• Assuming all residential sales are GST-free: New residential premises are taxable. Always check if the property is ‘new’ under the ATO definition.
• Not registering for GST when required: If you sell property in the course of an enterprise, you must register if your turnover exceeds $75,000. Even below that, you may need to register for certain supplies.
• Using the margin scheme incorrectly: The margin scheme has strict eligibility rules. Using it when you are not entitled can result in underpaid GST and penalties.
• Ignoring the going concern exemption: If you sell a leased commercial property, you may be able to make the sale GST-free. Failing to document the going concern agreement can cost the buyer 10%.
• Not apportioning mixed-use properties: If a property has both residential and commercial use, you must apportion the sale price and GST accordingly.
• Forgetting about foreign resident withholding: If you buy property from a foreign resident, you must withhold 12.5% and remit it to the ATO. Failure to do so makes you liable.

Expert Tip: Always keep detailed records of your property costs, renovations, and use. This will help you determine the correct GST treatment and claim any eligible credits.
