Tax Trap: Leaving Country Now Triggers Bitcoin Gains Tax

Bitcoin holders in Canada, Australia, and the UK are facing an unexpected tax bill when they leave their countries instead of when they sell their coins. According to Jeremy Savory, CEO of Millionaire Migrant, a relocation firm, more clients are now moving before an expected Bitcoin rally, as the planning question has shifted from 'where' to 'when'. This change is due to the automatic exchange of transaction data between jurisdictions under the CRS and CARF frameworks.

The OECD says 76 countries have committed to the Crypto-Asset Reporting Framework (CARF), which makes data visible across borders. Canada and Australia treat departure as a taxable event for residents holding appreciated assets, while the UK has no general exit tax but may claw back gains if the person returns too soon.

Cyprus introduced an 8% flat tax on crypto disposal gains in 2026, trading an informal zero for a statutory rate. Meanwhile, Türkiye offers a 20-year exemption for qualifying new residents with foreign-source income and gains. The US taxes worldwide income, but expatriation treats covered expats as having sold their entire portfolio the day before they give up their passport.
