On 16 April 2015, the protocol to the 1991 income tax treaty between Italy and Mexico entered into force. The protocol, signed 23 June 2011, replaces Article 25 (Exchange of Information) bringing it in line with the OECD standard for information exchange. The protocol also amends the name of the Italian competent authority, changing it to the Ministry of Economy and Finance.
The protocol is the first to amend the treaty, and applies from the date of its entry into force.
