If you owned your property on 12 May 2026, your future gain is about to be split in two
Budget night, 12 May 2026, is the line in the sand. Every property you already owned on that date is affected: from 1 July 2027, the ATO will split your capital gain into a pre- and post-2027 portion, and tax each one differently.
The catch — the size of each portion depends entirely on what your property is worth on 1 July 2027. Without a certified valuation on that date, you have no way to prove it, and no way to compare it against the ATO's own default method.

Budget 2026 · What Changed
Your Profit Gets Split in Two
A valuer works out what your property is worth on 1 July 2027. That single number sets the boundary between your pre- and post-Budget gain - and each side is taxed differently
The old rule still applies
This is the profit you already made. It's only half-taxed, just like today
(50% CGT discount).
The new rule applies
Profit made after that date works differently. What you paid gets bumped up for inflation (CPI indexation) instead of getting the 50% discount.
$550,000 before 1 Jul 2027 · half taxed
$150,000 after 1 Jul 2027 · new way
$550,000 before 1 Jul 2027 · half taxed
$150,000 after 1 Jul 2027 · fully taxed
In total, you made $700,000. But it's split into two parts
