Why this matters now · From 1 July 2027
Australia's capital gains rules change on 1 July 2027
For a sale on or after 1 July 2027 the 50% discount is replaced by indexation of the cost base plus a 30% minimum rate on the gain built up after that date. The gain built up before it keeps the discount, split at a 30 June 2027 valuation.
Who it affects
- Individuals and trusts selling an investment property from 1 July 2027
- Anyone holding a property on 30 June 2027, which is deemed reacquired at that date
- Foreign and temporary residents, who are excluded from the indexation
