Buildings or structures constructed on or after 20 September 1985 on land acquired before that date are also considered to be separate CGT assets from the original land. The major capital improvement threshold and 5% of capital proceeds rules do not apply to them. Therefore, they may be subject to CGT if you use them other than as your main residence.
Dwellings transferred after marriage or relationship breakdown
Special rules apply to dwellings transferred to you from a spouse, or a company or trustee of a trust, if the marriage or relationship breakdown rollover applies.
