Some services unavailable 23 - 24 November | myIR, gateway services and our self-service phone line will not be available from 3pm Saturday 23 November to 9am Sunday 24 November while we do planned system testing. This will not affect any tax entitlements or payments scheduled during this time.

Where you change from joint tenancy to tenancy in common, the acquisition date used for the bright-line test does not change and the bright-line period start date does not reset when the title is transferred.

This also applies if the change is from tenancy in common to joint tenancy. There is an example further down the page.

Changes in acquiring and removing additional shares in the same land

Where you acquired a share in residential land before 27 March 2021 and later acquire more of the same land on or after 27 March 2021, when the land is sold it will all fall into the bright-line period that applied at the time you acquired your first interest in the land. The original bright-line period starts from the date each increase in share takes place. See example below.

Example: Change from a joint tenancy to a tenancy in common

Tony and Michael bought a rental property as joint tenants in August 2019. 2 years later, they decide that if one of them dies, they want the share of the partner who dies to go to that partner’s children.

In June 2021, the title transferred to change their ownership of the property from a joint tenancy to a tenancy in common (50:50).

For the bright-line test to apply, there must be a disposal of residential land by either Tony, Michael or both of them. In this case, neither of them is treated as having disposed of land for the purposes of the bright-line test. Tony and Michael own the same land (the estate in fee simple) before and after the transfer.

Before the transfer, they each had an interest in the whole of the property and an equal separate share (that is, 50%). After the transfer, they each still have an interest in the whole of the property, and they each now have a 50% share. The acquisition date is not reset in June 2021 when the title transferred to change the form of co-ownership of the property.

If Tony and Michael dispose of the property in the future, the bright-line period starts in August 2019 when the property was first acquired by Tony and Michael.

Example: Additional shares acquired

Hina and Andy entered into a binding agreement to buy a rental property as tenants in common on 30 June 2018. Hina owns 50% and Andy owns 50%. Settlement was on 31 July 2018. Hina sells her shares to Andy on 31 August 2021 at market value. The title is transferred to Andy who now owns 100% of the property.

For the purposes of the bright-line test, Hina has disposed of her 50% interest in the land. This disposal is income under the bright-line test, as the disposal was within the applicable bright-line period of 5 years. Hina can deduct the amount she paid for her share of the property.

If Andy then sells the rental property shortly afterwards, he will also be subject to the 5-year bright-line period, because he entered into a binding sale and purchase agreement on 30 June 2018 to acquire the original share in the property. The bright-line test will apply as follows:

  • 50% share purchased on 31 July 2018 taxable if sold before 31 July 2023
  • 50% share purchased on 31 August 2021 taxable if sold before 1 July 2024 because 1 July 2024 is earlier than 31 August 2026.
