The calculator uses the latest ATO guidelines and updates regularly to reflect changes in tax rules.
From rental units in Sydney to farmland or commercial properties, you can estimate CGT on all investment property types.
If you’re eligible for the 50% CGT discount, the calculator factors it in automatically for properties held longer than 12 months.

The basic Capital Gains Tax formula is:
Capital Gain = Selling Price − Total Costs
Taxable Capital Gain = Capital Gain × 50%
If you’ve owned the asset for more than 12 months, you may only pay tax on half of the profit.
Step 1: Add Up Your Costs
Include:
Purchase price
Stamp duty and legal fees
Renovation costs
Selling expenses
Example
$700,000 + $30,000 + $20,000 = $750,000
Your total costs are $750,000.
Step 2: Calculate Your Profit
If you sold the property for $950,000:
$950,000 − $750,000 = $200,000
Your profit is $200,000.
Step 3: Apply the 50% Discount
Since the property was owned for more than 12 months:
$200,000 × 50% = $100,000
Result: Only $100,000 is added to your taxable income and taxed at your marginal tax rate.
This is a simplified example. Your actual Capital Gains Tax may vary depending on your income, capital losses carried forward, and the type of asset sold.”

The first stage of the reform is law and starts on 1 July 2027 (ATO, updated October 2026). More stages are still to pass, so check with us before you sell or buy. Our calculator works out tax at the current rules; ask us to model a sale after 1 July 2027.
You’ll need the purchase price, sale price, buying and selling costs, ownership details, purchase and sale dates, and records of major improvements. Accurate records help ensure your estimate reflects your actual tax position. A capital gains tax on property calculator or a capital gains tax on property calculator Australia can help organise these figures and provide a more accurate estimate.
Look for a calculator based on current ATO rules. A good capital gains tax calculator Australia should support property, shares, capital losses, and the 50% CGT discount. It should provide quick estimates and easy-to-understand results for different investment types.
It follows the ATO’s current rules: the 50% discount for assets held more than 12 months, capital losses applied in the ATO’s order, and the 2025-26 and 2026-27 tax rates. It works for property, shares and other assets, for individuals, companies and SMSFs, and links to the ATO pages behind the figures. For a large or complicated sale, have a registered tax agent check it before you lodge.
Yes. Many free capital gains tax calculator Australia tools are available online and can provide a reliable estimate. They’re ideal for understanding potential tax before selling an investment property, shares, or preparing your tax return.
If you’ve held an asset for more than 12 months, Australian resident individuals and trusts can generally reduce their capital gain by 50%, and only the rest is added to your taxable income. From 1 July 2027 the discount is replaced by indexation for the part of the gain made after that date; gains up to 30 June 2027 keep the 50% discount.
Enter the purchase price, selling price, buying and selling costs, ownership period, and any capital losses. The calculator then estimates your taxable gain based on current Australian tax rules. If you need to calculate capital gains tax property transactions, make sure you include renovation costs and selling expenses where applicable.
Some calculators support SMSFs and apply the special CGT rules that apply to super funds. This can help trustees estimate gains before preparing annual returns. A capital gains tax calculator Australia with SMSF support can simplify more complex calculations.
Calculate the difference between your sale proceeds and purchase cost, including brokerage fees. Apply any capital losses and, if you’ve held the shares for over 12 months, the CGT discount may also apply. A capital gains tax calculator can make the process easier and reduce manual errors.
Yes. Mobile-friendly CGT calculators are great for quick estimates. Just ensure the final figures in your tax return are based on complete records and current ATO guidelines. Many capital gains tax calculator Australia tools are designed to work seamlessly on smartphones and tablets.
The calculation depends on when the asset was originally acquired and when it was inherited. Inherited assets have special rules, so it’s important to use accurate information when estimating CGT. A capital gains tax calculator Australia may help with estimates, but professional advice is often recommended for inherited assets.
Some CGT calculators are backed by accountants who can provide tailored advice. This is especially useful for investment properties, inherited assets, trusts, SMSFs, and more complex tax situations. A capital gains tax on investment property calculator combined with professional advice can help property owners better understand their potential tax obligations.
