Get more from your property
Selling an investment property can feel like the final step in a long journey but it often comes with a big financial question mark. After all the effort and money you’ve put in, how much will you actually keep once the tax bill lands?
For many Australians, understanding how much capital gains tax on property they’ll pay is the key to knowing their true profit. The rules, exemptions, and calculations can seem complex, especially with terms like “cost base” and “CGT discount” in play.
This guide breaks it all down into simple steps so you can calculate your potential tax, understand available exemptions, and make confident, informed decisions before you sell.
What is capital gains tax on property?
First, let’s get one thing straight about Australian tax law. Capital Gains Tax, or CGT, is not a separate tax. It’s a component of your income tax, and you report and pay it as part of your annual income tax return filed with the Australian Taxation Office.
A capital gain is the profit you make when you sell a capital asset. This could be shares, business equipment, or in this case, a property. When you sell an investment property for more than what it cost you, that profit is a capital gain.
This gain tax is triggered by a CGT event, with the most common one being the sale of an asset. Other CGT events can include gifting a property, receiving an insurance payout for a destroyed asset, or a change in residency status. Understanding what constitutes a CGT event is the first step to figuring out your tax obligations for a gains tax property.
What are CGT exemptions and concessions?
The ATO has several rules about CGT exemptions. Understanding these can significantly lower the tax from selling investment property. The most common one relates to your home.
1. The main residence exemption
The most significant exemption is the ATO main residence exemption.
- If a property is your primary home for the entire time you own it, you usually don’t have to pay CGT when you sell it.
- To qualify, the property must have a dwelling on it, and you must have lived in it.
You generally cannot treat two properties as your main residence at the same time. This exemption also does not fully apply if you used part of your home to produce income, such as running a business from a home office or renting out a room.
2. Partial exemption when a home is rented out
What if you lived in the home for a while and then rented it out? In this case, you may be eligible for a partial main residence exemption. The gain is calculated based on the portion of time it was used to produce income.
For example,
- If you owned the property for ten years, lived in it for five, and rented it out for five, you would generally be taxed on 50% of the capital gain.
- A property valuation at the time it first becomes income-producing is often necessary for this calculation.
3. The six-year absence rule
If you move out of your main residence and rent it out, you can still treat it as your main home for up to six years. This means you could potentially sell it within that six-year period without paying CGT. A key condition is that during that time, you cannot treat any other property as your main residence.
If you move back into the home, a new six-year period starts if you decide to move out again later. This can be a very helpful rule for maintaining your exemption. Be sure you meet all the conditions before relying on it, as getting it wrong can lead to a surprise tax bill.
5 Steps on How to Claim Depreciation on Investment Property
How to calculate your capital gain (or loss)
To figure out your capital gain, you need to know your “cost base“. This isn’t just the purchase price of the property. The cost base includes most of the money you spent to acquire, hold, and sell the tax property.
Knowing this figure is crucial because a higher cost base means a lower capital gain. This directly reduces the amount of tax you might have to pay. Thorough and organised record keeping is your best tool here.
Step 1: What’s included in the cost base?
Your property’s cost base is made up of five main elements. It is extremely important to maintain good record-keeping of all these expenses. You will need to keep these records to accurately calculate your capital gain and prepare your tax return.
Here’s what you can generally include:
- Money paid for the property: This is the original purchase price.
- Incidental costs of buying and selling: Think of stamp duty, legal fees, surveyor fees, and real estate agent commissions.
- Ownership costs: These can include things like council rates, strata fees, and land tax, but only if the property was bought after 20 August 1991. You cannot include these costs if you have already claimed them as a tax deduction against rental income.
- Capital improvement costs: This covers money spent to improve the property’s value, like a major renovation, adding a deck, or installing a new kitchen. Basic repairs and maintenance costs are not included here.
- Costs to establish, preserve, or defend your title:This might include legal fees from a boundary dispute or similar legal actions.
Step 2: Calculating the actual gain
Once you know your cost base, the basic calculation is quite simple. You subtract your cost base from your capital proceeds. The capital proceeds are usually the sale price of the property, minus any direct selling expenses.
The formula looks like this:
Capital Proceeds – Cost Base = Total Capital Gains.
But what happens if the result is a negative number?
This means you’ve made a capital loss, which has its own set of rules.
You can’t deduct capital losses from your regular income, like your salary or business profits. However, you can use them to reduce capital gains in the same income year. A net loss carried forward can also be used to offset capital gains in future years, making the tracking of capital losses from previous years just as important as tracking gains.
How can you reduce your CGT liability?
While paying tax is unavoidable, there are legitimate ways to reduce your CGT liability. Using these strategies can help you keep more of the profit from your sale. It all comes down to careful planning.
1. The 50% CGT discount
This is the most common way to lower your CGT. To qualify,
- You must be an individual or a trust and have owned the asset for more than 12 months before selling it.
- This CGT discount is a major incentive for long-term investment.
- Companies are not eligible for the 50% CGT discount.
- This is an important distinction for business owners. It can influence how you decide to structure your investments.
2. Offset gains with losses
As shown in the example with Ben, capital losses are very useful. If you have other investments that have lost value, you might consider selling them in the same year as a profitable property sale. A capital loss can be carried forward indefinitely until it is used to offset a future capital gain.
- You cannot use a capital loss to reduce your regular taxable income, however. It can only be used against capital gains.
- This makes strategic selling of assets an important part of investment management.
3. Time the sale strategically
Since your net capital gain is added to your income, the timing of the sale matters. If you can, it might be better to sell in a year when your overall income is lower. For example, you might plan the sale for a year when you are on a lower salary, on leave, or have retired.
- The CGT event usually happens when you sign the contract of sale, not at settlement.
- Be mindful of this timing. A contract signed on 30 June falls in one financial year, while one signed on 1 July falls in the next.
4. Contribute to superannuation
Making a personal concessional contribution to your super fund can reduce your taxable income for the year. By lowering your overall income, you can reduce the marginal tax rate applied to your capital gain. There are annual caps on these contributions, so planning is essential.
3 methods to calculate capital gains tax on property
This is the big question. Once you have your gross capital gain, you need to figure out the net capital gains amount that gets added to your income. The ATO provides a few ways to do this, and choosing the right one can save you a lot of money.
The method you use depends mostly on how long you’ve owned the property and the type of entity that owns it. The tax calculation method is very important. Let’s look at the options to determine your total capital.
1. The CGT discount method
This is the most common and beneficial method for individuals. If you are an Australian resident for tax purposes and have owned the property for at least 12 months, you can use the CGT discount method. It lets you reduce your gross capital gain by 50%.
For example,
If your gross capital gain is $100,000, you can instantly reduce it to $50,000. You then add this $50,000 to your other taxable income for the year, such as salary or interest from personal bank accounts. Your remaining capital gain is then taxed at your marginal tax rate.
- This discount is a huge help and highlights why holding an asset for over 12 months is often a good strategy.
- That simple waiting period can make a massive difference to your final tax bill.
- Self-managed super funds can also access a discount, but it is 33.3%.
2. The indexation method
The indexation method is an older option that can only be used for assets acquired before 11:45 am (AEST) on 21 September 1999. If you bought your property after this date and time, this method is not available. It cannot be used in conjunction with the CGT discount.
- This method allows you to increase your cost base by applying an indexation factor based on the Consumer Price Index (CPI) up to September 1999.
- This accounts for inflation’s effect on the cost base.
- You must choose either the indexation method or the discount method; you can’t use both, so you should calculate the capital gain tax with both to see which is better.
3. The basic method
This is the simplest method and is often called the ‘other’ method. It’s used when you cannot use the discount or indexation methods. This is typically the case if you’ve owned the property for less than 12 months.
With this method,
- You don’t get any reductions.
- Your entire net capital gain is added to your taxable income.
- This shows the significant tax cost of “flipping” a property within a year.

Example 1: Working out CGT for a single asset
Let’s use a practical example. Imagine Sarah bought an investment property in May 2015 for $400,000. She incurred several costs associated with the purchase.
Her initial costs included $15,000 in stamp duty and $2,000 in legal fees. Over the years, she spent $25,000 on renovations. In March 2024, Sarah sold the property for $650,000, which is a CGT event. The real estate agent’s commission and legal fees for the sale totalled $18,000.
First, we need to calculate the property’s cost base.
- Purchase price: $400,000
- Stamp duty: $15,000
- Purchase legal fees: $2,000
- Renovations: $25,000
- Sale costs (commission, legal): $18,000
- Total Cost Base: $460,000
Next, we calculate the capital gain.
- Capital Proceeds (Sale Price): $650,000
- Total Cost Base: $460,000
- Gross Capital Gain: $190,000 ($650,000 – $460,000)
Since Sarah owned the property for more than 12 months, she can apply for the 50% CGT discount. This reduces her taxable capital gain. The discounted gain is $95,000 ($190,000 x 50%), which she then adds to her other income for the year.
Example 2: Working out CGT for multiple assets
Now, let’s consider a situation with multiple assets. Ben sold an investment property and made the same capital gain as Sarah: $190,000. Like Sarah, he is eligible for the 50% CGT discount, which would make his gain $95,000.
However, earlier in the same financial year, Ben also sold some shares and incurred a capital loss of $15,000. Ben can use this capital loss to reduce his capital gain from the property.
You must apply capital losses to capital gains before applying any discounts. Ben’s calculation looks like this:
- Gross Capital Gain (Property): $190,000
- Capital Loss (Shares): -$15,000
- Adjusted Capital Gain: $175,000
Now, Ben can apply the 50% CGT discount to the adjusted gain. The discounted gain is $87,500 ($175,000 x 50%). So, Ben will add $87,500 to his assessable income for the year, not $95,000.
Are there any CGT considerations for business owners
As a business owner, you might hold property through different structures, not just in your personal name. This can change how CGT applies. It is something you need to be aware of before making any transactions.
If your property is owned by a company, the rules are different.
- Companies are not eligible for the 50% CGT discount.
- The full capital gain is added to the company’s assessable income and taxed at the current company tax rate.
For those using a Self-Managed Super Fund (SMSF) to hold property, the rules for super funds change again. For a complying super fund in accumulation phase, gains on assets held for more than 12 months are taxed at an effective rate of 10%. If the fund is in the pension phase and meets certain requirements, the capital gain could even be tax-free.
Small business CGT concessions
If the property was used in your business, you might be able to get even more help. The small business CGT concessions can significantly reduce or even eliminate a capital gain. These are some of the most generous tax breaks available from the taxation office.
There are four concessions available:
- The 15-year exemption
- The 50% active asset reduction
- The retirement exemption
- Rollover concession.
The rules to qualify can be detailed. Correctly applying them is vital, as the savings can be huge.
You generally need to be a small business entity with an aggregated turnover of less than $2 million or have a net asset value below $6 million. Given the value, making decisions based on this information alone is risky. Getting specific advice for your situation is a very smart move.
How and when to pay Capital Gains Tax
A common question is about how you actually pay the tax. You don’t send a separate cheque to the ATO for the gain. Instead, you need to pay capital gains tax as part of your regular income tax assessment.
- When you complete your annual tax return, you declare your total capital gains and losses.
- The calculated net capital gain is included with your other income, and the ATO issues a notice of assessment for the total tax payable.
- You must pay this amount by the due date specified on the notice.
It’s important to plan for this tax liability. You can’t use consumer finance like a credit card or car loans to pay the ATO directly. You need to ensure you have set aside sufficient funds from the sale proceeds to meet your obligation and pay capital gains when required.
When do you pay capital gains tax on an investment property?
The tax isn’t paid immediately after you sell the property. You will report the capital gain in your income tax return for the financial year in which the sale contract was signed. Your total tax liability, including the CGT component, is then calculated using a tool like a capital gains tax calculator or by an accountant.
Once you receive your notice of assessment from the ATO, it will show the total tax you owe. This amount will be due by the date specified on the notice. It is important to set aside enough funds from the sale to cover this future tax bill.
Conclusion
Working out how much is capital gains tax on property can feel like a lot to handle. Breaking it down into cost base, capital proceeds, and applicable discounts makes it much more manageable. The key is to understand that the gain is part of your income tax, not a separate beast to pay CGT on.
Always remember the importance of your cost base and keeping great records of all property-related expenses. Holding onto an investment property for more than 12 months can cut your taxable gain in half with the CGT discount. This is a simple but powerful strategy for individuals.
Every situation is different, especially for business owners with various structures. While this guide provides a solid foundation of the main content, it is not a substitute for professional guidance. It’s wise to seek professional advice to ensure you make the best financial choices for your circumstances.

FAQs on how much is capital gains tax on property in Australia
- Trusts: Capital gains can be distributed to beneficiaries, who are taxed at their marginal rates, possibly reducing overall CGT if beneficiaries are in lower tax brackets.
- SMSFs: Gains inside an SMSF held for over 12 months benefit from a 33% discount, and if assets are sold during the pension phase, gains may be tax-free, offering significant tax efficiency.
Yes, via the Small Business Roll-over Concession, eligible small businesses can defer CGT by using proceeds from the sale of an active business asset to acquire or improve a replacement asset. This deferral lasts until the replacement asset is sold or stops meeting the “active asset” test. It’s a powerful way to manage tax timing but be mindful of the detailed eligibility and replacement timing rules.
Significantly. Non-residents cannot access the main residence exemption, even if they previously lived in the home. Additionally, from 2025, non-residents lose access to the 50% CGT discount and may face higher withholding tax rates on property sales. Timing your sale before tax residency changes can make a major difference to your tax outcome.
