The End of the 50% CGT Discount: Australia’s New Crypto Tax Reality

Australia has officially passed legislation that will phase out the 50% capital gains tax discount for assets like cryptocurrency. Starting July 2027, a new cost-based indexation model will replace the long-standing incentive. Here is what you need to know to navigate the changing regulatory landscape.

A Major Shift for Australian Investors

For years, the 50% capital gains tax (CGT) discount has been a cornerstone of Australian investment strategy, allowing long-term holders of assets—including cryptocurrency—to significantly reduce their tax liability. That era is coming to a close. On June 25, 2026, the Australian Parliament passed new legislation that effectively dismantles this discount, signaling a seismic shift in how crypto gains will be treated at the tax office.

New legislative changes in Australia are forcing crypto investors to rethink their long-term strategies.

What Changes in 2027?

The new law, which takes full effect on July 1, 2027, removes the 50% CGT discount entirely. In its place, the government is introducing a cost-based indexation model. This system is designed to adjust the cost base of an asset for inflation, ensuring that investors are not paying tax on 'paper gains' caused solely by rising prices over time.

The 50% CGT discount is officially set to be phased out.
The change applies to assets including Bitcoin, ADA, property, and shares.
Cost-based indexation will replace the discount starting July 1, 2027.
The legislation passed through both houses of Parliament in June 2026.

Investor vs. Trader: Knowing Your Status

Understanding your tax obligations requires knowing whether the Australian Taxation Office (ATO) views you as an investor or a trader. While most Australians fall into the 'investor' category, those executing trades in an 'organized, business manner' may be classified as traders. Traders generally do not qualify for capital gains discounts but can write off business-related expenses like internet and software costs. The line between these categories can be thin, and the ATO continues to increase its scrutiny of crypto-related activity.

Every dollar of profit that you make selling your ADA, your Bitcoin, your shares, your property, whatever it is, gets taxed under the completely new system.
