  • Capital gains tax property exemption tool

    If you've sold a property or plan to sell one (or otherwise dispose of one), you can use this tool to work out what percentage of your capital gain is exempt from capital gains tax (CGT).

    You need to have owned the property as an individual, either in your own right or jointly with someone else. The tool covers situations where the property is (or was):

    • your home, even if you lived in and then left it vacant for a period of time or used part of it to produce income
    • a rental property
    • a vacant block of land.

    From 1 July 2021, you may be entitled to a capital gains tax exemption when you have a formal granny flat arrangement with an elderly or disabled person to live in your property. For more information, see Granny flat arrangements and CGT.

    Foreign residents can no longer claim the main residence CGT exemption when they sell property in Australia after 30 June 2020, except in certain circumstances. For more information, see Main residence exemption for foreign residents.

    Before you use this tool

    The tool results are based on the information you enter. You should use these results as an estimate and for guidance purposes only.

    If you use this tool before disposing of your interest in a property to estimate the proportion of capital gain or loss that is taken into account for tax purposes, you should use the tool again after the disposal with updated information and use that result to assist in preparing your tax return.

    Information you need for this tool

    You'll be asked for:

    • the date you acquired the property and the date you sold it (or will sell it)
    • other information depending on your particular circumstances – for example, if you rented the property for a while, you'll need to enter the period it was rented.

    What this tool doesn't cover

    This tool won't cover your situation if:

    • the property is on more than two hectares of land
    • you owned two or more properties that had both been your main residence and the periods you owned them overlapped
    • you and your spouse, or you and your dependent children, had different main residences at the same time
    • the property is being transferred to or from you because of a marriage or relationship breakdown
    • you inherited the property on or after 20 September 1985 and there was a dwelling on it when you sold it
    • you were absent from the property more than once and you used it to produce income (such as renting it out), and either  
      • one of these absences is more than six years, or
      • during your absence the property was completely vacant (you didn't reoccupy it)
    • you used a part of the property, other than the dwelling, to produce income
    • you had a building or other structure constructed on the property and  
      • you acquired the property before 20 September 1985 and the building works were after that date, or
      • you sold the property less than three months after you first occupied it
    • you acquired one property (or properties) pre-CGT and another property (or properties) post CGT and you amalgamated the titles
    • your property is being compulsorily acquired
    • the property was used for affordable housing – for eligibility details for claiming up to an additional 10% capital gains discount, see CGT discount for affordable housing
    • the CGT event relates to property with a granny flat agreement in place, see Granny flat arrangements and CGT.

    If your situation is listed above, see Capital gains tax – Your home and other real estate to find out how CGT applies to your circumstances.

    Maximum exemption

    The tool is designed to give you the maximum exemption for capital gains. It automatically increases your exemption percentage to cover some or all of those periods when you didn't occupy the property, provided you met certain conditions. You'll be disadvantaged by the exemption percentage being increased automatically if you made a capital loss and either:

    • you were absent from the dwelling after occupying it as your main residence
    • you built or renovated a dwelling on the property and then occupied it as your main residence.
