Anyone who fails to nail down what those assets are worth at that point risks gifting the tax office a large slice of their future gains. The exposure is not small, experts warn some investors could be out hundreds of thousands of dollars.
Australia’s capital gains tax rules will shift on July 1 2027, replacing the long-standing 50% CGT discount with an inflation indexation approach and a minimum 30% tax on real gains. Profits that accrue up to June 30 2027 will still qualify for the current 50% discount, preserving that benefit for past growth.
Any gain that arises from July 1 onward will instead be taxed under the new framework, which is expected to be less generous for many. The crucial job is fixing an asset’s value at the exact point the rules switch.
Investors need a defensible valuation that clearly separates pre-July 1 gains from those that build afterwards, especially for assets like investment properties, private companies and unlisted start-ups where there is no daily market price. A casual estimate or outdated appraisal may not stand up if the tax office later challenges how much of the total gain qualifies for the old 50% discount.
Using recognised valuation methods and independent professionals becomes more important as the potential tax saving grows. Without that evidence, the risk is that a larger share of the overall gain is pushed into the post-2027 higher-tax segment of the equation.
