On 24 June 2016, Turkey published in the Official Gazette the law ratifying the pending protocol to the 1987 income tax treaty with Belgium. The protocol, signed 9 July 2013, is the first to amend the treaty. It updates the definition of competent authority in respect of Belgium under Article 3 (General Definitions), replaces Article 26 (Exchange of Information) to bring it in line with the OECD standard for information exchange, and replaces Article 27 (Assistance in Recovery).

The protocol will enter into force once the ratification instruments are exchanged, and will apply from 1 January of the year following its entry into force.
