"Will the new tax changes hurt me?"
It's the question I'm hearing most from investors right now.
New research from the e61 Institute, an independent economic research institute, gives a clearer answer than the headlines.
They applied the CGT and negative gearing changes to ~920,000 real housing investments held between 2008 and 2025.
53% of investors would pay more tax. 43% would pay less.
That's not a hit to every investor. It's a split, and it runs through both taxes:
• Capital gains: lower for 54% of investments, higher for 42%
• Rental income: higher for 49% of investors, lower for 28%, the rest largely neutral
Which side you land on comes down to your borrowing, your expected growth, whether you buy established or new, and your tax rate when you sell.
I've broken it down in the slides.
One thing to keep in mind. This is an "all else equal" exercise. e61 applied the new rules to what actually happened between 2008 and 2025, and the model holds investor behaviour constant. Rates, prices and behaviour will all move from here. So read the 53/43 split as a map of who is exposed under the rules, not a forecast of anyone's outcome.
Which is the point: the averages tell you less than your own numbers do.
The policy is the same for everyone. The outcome isn't.
