Australia scraps its 50% crypto tax break — holders will need a new playbook

Australia's government is preparing one of the most notable crypto taxation reforms in years: the long-standing 50% capital gains tax (CGT) discount that holders of assets owned for over 12 months have relied on for decades is set to be scrapped entirely.

What's Changing

Instead of the familiar model — paying tax on only half the profit when an asset is held for more than a year — a more complex system is being introduced based on cost-base indexation: the purchase price will be adjusted for inflation over the holding period, and tax will apply to the real, not nominal, gain. A new minimum capital gains tax rate of 30% is being introduced at the same time.

When It Takes Effect

The changes are expected to be included in the Albanese government's fiscal year 2027 budget, with the reform itself taking effect at the end of that fiscal year — meaning July 2027. That gives Australian crypto holders roughly a year to prepare for the new accounting regime.

What Happens to Gains Already Accrued

Gains accrued before the reform takes effect are protected under the old rules, meaning holders will need to carefully track profits earned before and after the transition date separately. There's also a one-year grace period for assets acquired after May 10: those will still qualify for the current 50% discount. Assets purchased before May 10 will get a partial exemption, with the applicable discount calculated proportionally based on how long the asset was held under each of the two tax regimes.

Why This Matters Beyond Australia

Australia is one of the larger developed economies with relatively clear crypto tax rules, and how it restructures its CGT system often becomes a reference point for other jurisdictions considering similar reforms. The shift from a flat discount to inflation indexation signals that regulators are increasingly looking to tax the real, rather than inflationary, increase in digital asset value — which for long-term crypto holders could mean a higher effective tax burden than before, even under a formally lower nominal rate.
