The grandfathering cut-off was 7:30pm AEST on 12 May 2026, and it has already passed. Whether you keep negative gearing is now settled by two things you already know.
Nothing is sent anywhere. This runs entirely in your browser.
Negative gearing is not being abolished. The losses are being ring-fenced, which is a different thing and it matters for the arithmetic.
A rental loss on any investment property is deductible against your other income, including your salary. If the loss exceeds your income it carries forward.
The same loss is deductible only against rental income or capital gains from residential property. It no longer reduces the tax on your salary.
Unused losses still carry forward indefinitely and offset residential property income in later years. Nothing is forfeited, it is deferred.
The same Act replaces the 50% CGT discount with cost base indexation and a 30% minimum tax, from the same date. This part cannot be calculated precisely yet, and it would be dishonest to pretend otherwise.
From 1 July 2027 the 50% discount ends for individuals, trusts and partnerships. Gains that accrued before that date keep the discount, so an asset held across the date is split.
Complying super funds keep the one third discount. Companies never had one. The main residence exemption, the four small business concessions and the 60% affordable housing discount are all retained.
Tranche 1 is framework legislation. It does not yet specify which inflation series is used, how often it is applied, or how a gain straddling 1 July 2027 is apportioned between the two regimes.
Those three details determine the answer, so any calculator giving you a precise indexed figure today is guessing at them.
These are the ones the legislation leaves genuinely open, rather than the ones a calculator can settle.
