Tax identification number for automatic exchange of information

On 1 January 2017, the legal basis for the international automatic exchange of information in tax matters (AEOI) came into force in Switzerland. The new global standard for AEOI is intended to prevent cross-border tax evasion. To date, around 100 countries have committed to adopting this standard.
