Crypto-assets were long a gap in automatic exchange of information, because they are often held not with banks but with specialised providers or in own wallets. The CARF closes this gap for assets that pass through crypto service providers.
Who reports and what
Reporting providers are those carrying out exchanges between crypto-assets and fiat currencies or between different crypto-assets for clients, as well as certain transfers. They identify clients’ tax residence and report aggregated transaction information. The tax authority exchanges the data with partner states, similar to AEOI on financial accounts.
Status in Switzerland
Switzerland has committed to implementation. Parliament approved the crypto AEOI agreement in the final vote of 26 September 2025. According to the State Secretariat for International Finance, AEOI on crypto-assets will be implemented from 1 January 2027 at the earliest; parliament decides when it is effectively activated with partner states.
Significance for family offices
Anyone holding crypto-assets in family structures should document which providers they pass through and which tax residences are affected. For AML compliance, the source of wealth remains a central issue regardless of the CARF, especially for crypto wealth.
