The first thing to work out: when did you buy?
The negative gearing changes apply differently depending on when you bought (or buy) the property. Three groups, three quite different positions.
You bought before 7:30pm AEST on 12 May 2026
Including contracts signed but not yet settled before that time. You’re fully grandfathered for negative gearing — you can continue to deduct rental losses against other income until the property is sold, regardless of when that is.
The CGT changes still apply to gains accruing from 1 July 2027, but the 50% discount remains on gains up to that date. Values will need to be established as at 1 July 2027 (either by valuation or an ATO apportionment formula).
You buy an established property between now and 30 June 2027
You can negatively gear during this window — but only until 30 June 2027. From 1 July 2027, rental losses on established property purchased in this window can only offset other residential property income, not your salary.
This is the most easily misunderstood group. The grandfathering applies to pre-12 May 2026 purchases only. Properties bought between 13 May 2026 and 30 June 2027 do not get lifetime negative gearing — only a short window.
You buy an established property from 1 July 2027
No negative gearing against other income. Rental losses from established property can only be offset against other residential property income (rent or capital gains on residential property), and can be carried forward.
New builds remain negatively geared. Knock-down rebuilds and substantial renovations don’t count as new builds. A previously-sold property doesn’t count unless it was first owned by the builder and unoccupied for less than 12 months.
