According to a recent update from the Austrian Federal Ministry for Europe, Integration and Foreign Affairs, the protocol to the 1971 income and capital tax treaty with Belgium will enter into force on 1 March 2016. The protocol, signed 10 September 2009, is the first to amend the treaty. It replaces Article 26 (Exchange of Information), bringing it in line with the OECD standard for information exchange.
The protocol applies from 1 January 2017.
