If you are an Australian crypto investor, the tax framework you have relied on for more than two decades is about to change in a meaningful way. Australia has passed the Treasury Laws Amendment (Tax Reform No. 1) Act 2026, the most significant overhaul to the country’s capital gains tax system in over 25 years. The change eliminates the 50% capital gains tax discount that currently benefits long-term holders and replaces it with a more complex system. The deadline is 1 July 2027, and what you do between now and then could affect how much tax you ultimately owe.
