Exchange of information

Convention on Mutual Administrative Assistance in Tax Matters

 

Last updated - July 2014

Additional countries and jurisdictions agreed to join more than 60 other countries in tax co-operation through a key multilateral tax instrument during the first day of a global meeting in Jakarta, Indonesia, on 21 November 2013.

The Convention was developed jointly by the OECD and the Council of Europe in 1988 and amended by Protocol in 2010.  The Convention is the most comprehensive multilateral instrument available for all forms of tax cooperation to tackle tax evasion and avoidance, a top priority for all countries.

The Convention was amended to respond to the call of the G20 at its April 2009 London Summit to align it to the international standard on exchange of information on request and to open it to all countries, in particular to ensure that developing countries could benefit from the new more transparent environment. The amended Convention was opened for signature on 1st June 2011. 

 

Since 2009 the G20 has consistently encouraged countries to sign the Convention including most recently at the meeting of the G20 Leaders Summit in September 2013 where the communique stated “We call on all countries to join the Multilateral Convention on Mutual Administrative Assistance in tax Matters without further delay.”  Currently over 60 countries have signed the Convention and it has been extended to over 10 jurisdictions (Chart of Signatures). This represents a wide range of countries including all G20 countries, all BRIICS, almost all OECD countries, major financial centres and a growing number of developing countries.

 

The Convention has now taken on increasing importance with the G20’s recent call for automatic exchange of information to become the new international tax standard of exchange of information. The Convention provides the ideal instrument to swiftly implement automatic exchange.

 

The amended Convention facilitates international co-operation for a better operation of national tax laws, while respecting the fundamental rights of taxpayers. The amended Convention provides for all possible forms of administrative co-operation between states in the assessment and collection of taxes, in particular with a view to combating tax avoidance and evasion. This co-operation ranges from exchange of information, including automatic exchanges, to the recovery of foreign tax claims.

 

 

For more information on the amended Convention see the flyer (also available in Spanish) which provides a brief overview on the Convention.  For answers to frequently asked questions regarding the amended Convention please see the Information Brief Multilateral Convention.

 

The amended Convention is also available in French, Spanish (unofficial translation) and Portuguese (unofficial translation).
