Switzerland to Share Crypto Holder Data with 74 Countries

In Summary

  • Switzerland will share crypto holder data with 74 countries under OECD’s CARF starting 2027
  • Exchange excludes the US and Saudi Arabia, pending reciprocity and compliance
  • Legal framework to take effect January 2026, with data transmission starting in 2027
  • Move balances global tax compliance with growing domestic crypto use


Catenaa, Wednesday, June 11, 2025 –Switzerland’s Federal Council approved automatic exchange of crypto-asset data with 74 jurisdictions starting in 2027 under the OECD’s Crypto-Asset Reporting Framework (CARF), marking a significant step toward global tax compliance in digital assets.

The data-sharing agreement covers all European Union member states, the United Kingdom, and most G20 countries, but notably excludes the United States and Saudi Arabia.

Exchanges will proceed only if partner countries meet strict reciprocity and compliance standards outlined by CARF.

The Swiss parliament is currently reviewing the legal basis for the data-sharing framework, which is expected to come into force on January 1, 2026.

The first actual transmission of crypto data will begin the following year. Authorities said partner jurisdictions will undergo periodic reviews to ensure ongoing adherence to the framework’s technical and legal requirements.

Switzerland’s move places it among the earliest countries to adopt the OECD’s global crypto reporting standards. Officials noted the list of participating countries may grow over time as international interest and regulatory frameworks evolve.

Meanwhile, Switzerland’s domestic crypto landscape advances independently, highlighted by Spar Switzerland’s recent launch of Bitcoin payments at all stores using the Lightning Network.
