Automatic exchange of information (AEOI)

27.01.2020 - 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 107 partner states. The AEOI has now been activated with 97 partner states (as at 1 January 2020). Switzerland's network of AEOI partner states thus includes all EU and EFTA member states, almost all G20 and all OECD states, Switzerland's most important economic partners and the world's leading financial centres. Financial account information was successfully exchanged with a total of 75 partner states at the end of September 2019. The selection of further partner states will depend on future developments at the international level (other states' commitments; Global Forum's Plan of Action for Developing Countries Participation in AEOI).

The Global Forum on Transparency and Exchange of Information for Tax Purposes (Global Forum) examines the domestic implementation of the AEOI standard by means of peer reviews. The aim is to create a level playing field worldwide. As with the exchange of information upon request, the Global Forum examines the domestic implementation of the AEOI standard by means of peer reviews. These will begin this year. To ensure the integrity of the AEOI standard from the outset, its key elements, including the national AEOI legal foundations, undergo a preliminary review in a phased process. In the context of this preliminary review, the Global Forum made recommendations to Switzerland. The proposal to amend the Federal Act and the Ordinance on the International Automatic Exchange of Information in Tax Matters aims to take the necessary measures to implement the Global Forum's recommendations. This concerns, among other things, certain due diligence and registration obligations, the inclusion of a document retention obligation for financial institutions, as well as definitions. Some exceptions are also to be removed or adapted. The Federal Council adopted the dispatch on the amendment of the AEOI Act on 20 November 2019. Parliament will consider the bill over the course of this year, so that it is expected that the Federal Council will be able to bring the amendments into force on 1 January 2021.
