Switzerland Approves CARF MCAA and the List of Partner States for the Automatic Exchange of Information in Crypto Assets

On June 6, 2025, the Federal Council of Switzerland adopted the Decree on the approval of the introduction of the international automatic exchange of information (AEOI) concerning crypto assets with 74 partner states. This step serves as the continuation of the bill adopted in February 2025, according to which the Federal Council adopted the Crypto-Asset Reporting Framework Multilateral Competent Authority Agreement (CARF MCAA) related to the automatic exchange of information for tax-relevant crypto asset matters, which will enter into force on January 1, 2026.

The Council has included 74 countries active on the crypto market with which Switzerland should automatically exchange crypto assets information starting from 2026. The list contains all EU member states, the United Kingdom and most G20 countries (the USA and Saudi Arabia are not included). Ukraine is also listed in the document.

An exchange will take place if the partner states are interested in exchanging information with Switzerland and if they fulfill the requirements of the Crypto-Asset Reporting Framework developed by the Organization for Economic Co-operation and Development (OECD). Following the bilateral activation of the agreement, the accountable providers of crypto services will be obligated to collect information on relevant transactions by crypto asset users who are tax residents in partner states in accordance with the AEOI and report it to the competent authority – Federal Tax Administration. If necessary, the Federal Council can take the measures provided for in the agreement, such as suspending the data exchange with a non-compliant partner.

It is planned the bill will enter into force in 2026, and the first exchange of data will occur in 2027.
