Automatic exchange of information between Switzerland and EU: Federal Council adopts dispatch on Protocol of Amendment
During its meeting on 24 June 2026, the Federal Council adopted the dispatch on the Protocol of Amendment to the Agreement between Switzerland and the European Union (EU) on the automatic exchange of financial account information to improve international tax compliance. The Agreement will be aligned with the revised OECD standard and also contains new provisions on administrative assistance for the recovery of VAT claims. The overwhelming majority of consultation participants agree with the proposal.
As English is not one of Switzerland's official languages, only the most important information on the Federal Tax Administration is translated into English. This translation is provided for information purposes only and has no legal force. Please refer to the German, French or Italian original version.
What is AEOI?
On 15 July 2014, the Council of the Organisation for Economic Co-operation and Development (OECD) adopted the new global standard for the international automatic exchange of information in tax matters (AEOI standard). So far, more than 100 countries, including all major financial centres, have committed to adopting this standard, including Switzerland.
