GST Margin Scheme Guide for Australian Property Investors
Buying or selling property in Australia can get tricky when GST is involved. This scheme is a legal method that helps property investors and developers pay less GST by only taxing the profit margin, not the full sale price. In this guide, I want to share that you’ll learn everything you want to know about this. We’ll explain how it works, who can use it and how you can calculate it accurately using a free GST calculator.

What Is the Margin Scheme in Property Sales?
Under this scheme, you only paying GST that is 10% on the difference between the price you bought a property for and the price you sold it for. This makes it easier to calculate the GST when purchasing or selling property.
For example, if you bought a property for $500,000 and sold it later for $700,000, you would only pay GST on the $200,000 profit, not on the full $700,000.
This scheme helps property investors and developers pay less tax in a legal way. Without this scheme, you’d have to pay GST on the full selling price, which can be a large amount.

Small Business / BAS Implications
If you run a property investment business, this scheme can really help you save money and make reporting easier.
- Reduce GST: You only pay GST on the profit margin, not the full sale price. This can save a lot, especially if you sell multiple properties in a year.
- Simplify BAS reporting: Since GST is calculated only on the margin, filling out your Business Activity Statement (BAS) becomes much easier. Less manual calculation means fewer mistakes.
- Easier tracking of multiple sales: If you have several property transactions, for this process, using a calculator helps you quickly check the GST payable for each sale.
Tip: Always use a reliable GST calculator to save time and avoid errors when reporting to the ATO
Who Can Use the Margin Scheme?
To apply this scheme, you must follow these rules set by theAustralian Taxation Office ATO. Not every property sale can use this.
- The property must be new or substantially renovated
- You must not claim input tax credits on the purchase
- You must be registered for GST in Australia
- The sale must not be a residential property already sold before 1 July 2000
Always check if you’re eligible before calculating to avoid mistakes. It’s also important to know that some property type like land, sold separately from buildings, may not qualify
When it Can’t Be Used
This method is not available for every property sale. There are certain situations where you can’t use it.
1. Properties Sold Before 1 July 2000
Properties sold before 1 July 2000 are generally GST-free in Australia, so it doesn’t apply. This means you can’t use this scheme to reduce GST on older residential properties.
2. Land is sold separately from buildings in some cases
If you sell land and buildings separately, it may not be allowed for the land portion. This usually happens when the land is sold as a standalone lot rather than part of a new or renovated property.
3. If input tax credits have been claimed on the purchase
If you claimed input tax credits when buying the property, this scheme can’t be used. This is because you’ve already received a tax benefit and applying it would double-count the GST reduction.
Tip: Always check eligibility with the ATO or a tax professional before applying this to make sure your sale qualifies.

How to Calculate Margin Scheme
Here’s an easy step-by-step guide to calculate it manually and see how the calculator can help you. Working out GST can be a bit tricky, but our tool makes it simple.
Manual Calculation Steps:
- Determine the purchase price of the property: This is the original cost you paid when acquiring the property.
- Find the selling price: This is the price at which you intend to sell the property.
- Calculate the margin: Take the selling price and subtract the purchase price to find the profit margin.
- Apply GST: Multiply the margin (the difference between selling and purchase price) by 10%, which is Australia’s GST rate.
Example:
| Property Purchase Price | Selling Price | Margin | GST Payable (10%) |
| $500,000 | $700,000 | $200,000 | $20,000 |
| $450,000 | $600,000 | $150,000 | $15,000 |
| $800,000 | $950,000 | $150,000 | $15,000 |
When you are dealing with several property sales, a GST margin scheme calculator makes your work easier and more accurate. It also saves time compared to doing the calculations manually.
How Margin Scheme Helps Save Money
Using it can lead to significant savings:
- Only pay GST on the margin instead of the full selling price.
- Simplifies reporting for activity statements.
Reduces the overall tax liability for property sales.
For property investors selling multiple properties in a year, these savings add up quickly. That’s why our calculator with GST is an essential tool for Australian property businesses.
Calculating GST Under the Margin Scheme
Here are two main methods approved by the ATO to calculate GST.
1. Consideration Method
- GST is calculated on the difference between the sale price and the original purchase price.
- This is the easiest method, and it’s commonly used in regular sales.
2. Valuation Method
- GST is calculated using the property’s value when you bought it, not the actual price you paid for it.
- When you don’t know the actual purchase price or don’t have complete records, this method is very helpful.
Both methods are available in our calculator, so you can easily compare the results and choose the one that works best for you.
