The tax exchange of information agreement (TIEA) between Iceland and Switzerland has been entered into force on 1 January 2017 through an exchange of notes (EoN). It applies from the same date of its entry into force. The agreement was signed on 26 October 2016 by Switzerland and on 28 October 2016 by Iceland. The agreement has projected to ensure that Iceland and Switzerland will be able to start the automatic exchange of financial account information according to the OECD Automatic Exchange of Information Agreement of 2014, base on the Council of Europe – OECD Convention on Mutual Administrative Assistance in Tax Matters (MAA) of 1988. This exchange of information agreement (2014) has been amended by the 2010 protocol approved by the Iceland – Switzerland Joint Declaration on Automatic Exchange of Information (2016).
