Automatic exchange of information (AEOI)

14.01.2019 - The global standard on the automatic exchange of financial account information (AEOI) aims to increase tax transparency and thus prevent cross-border tax evasion. To date, more than 100 countries, including Switzerland, have committed themselves to adopting this standard. Domestic bank client confidentiality in Switzerland is not affected by the AEOI.

The legal foundations for the AEOI have been in force since 1 January 2017. To date, Parliament has approved the introduction of the AEOI with 89 partner states (as at 1 January 2019). Switzerland's network of AEOI partner states thus includes all EU and EFTA member states, almost all G20 and OECD states, Switzerland's most important economic partners and the world's leading financial centres. Financial account information was successfully exchanged with 36 partner states for the first time at the end of September 2018. Based on current international developments, a further 18 partner states are currently to be added to Switzerland's AEOI network, and the AEOI should be implemented with them from 2020/2021 onwards. The corresponding consultation procedure was initiated on 7 December 2018 and will last until 20 March 2019.
