On 20 April 2016, the Italian Senate approved for ratification the pending protocol to the 1976 income and capital tax treaty with Switzerland. The protocol, signed 23 February 2015, replaces Article 27 (Exchange of Information) to bring it in line with the OECD standard for information exchange. It will enter into force once the ratification instruments are exchanged, and will apply for requests made on or after the date of entry into force.
