The agreement between Switzerland and the European Union (EU) on the automatic exchange of information (AEOI) in tax matters is helping to combat cross-border tax evasion. The agreement has been in force since 2017 and applies to all EU member states. It implements the global standard on AEOI of the Organisation for Economic Cooperation and Development (OECD).

In 2004, Switzerland and the EU concluded a taxation of savings agreement on combating cross-border tax evasion as part of the Bilaterals II package of agreements. This was replaced by the agreement between Switzerland and the EU on the automatic exchange of financial account information in tax matters, which was signed on 27 May 2015. The new agreement implements the OECD global standard on AEOI. In this context, Switzerland and all of the EU member states have been collecting account data since 2017, and have been exchanging this data since 2018.  By implementing the AEOI standard, Switzerland and the EU are making an important contribution to the prevention of tax evasion.
