On 26 August 2016, officials from France and Portugal signed a protocol to the 1971 income tax treaty between the two countries. According to a release from Portugal's Ministry of Finance, the protocol updates Article 27 (Exchange of Information) to bring it in line with the OECD standard for information exchange and adds provisions for assistance in the recovery of taxes. The protocol is the first to amend the treaty and will enter into force after the ratification instruments are exchanged.
