15 countries sign updated Convention on Mutual Assistance in Tax Matters

In April 2009, the G20 called for action “to make it easier for developing countries to secure the benefits of the new cooperative tax environment, including a multilateral approach for the exchange of information.” In response, the OECD and the Council of Europe developed a Protocol amending the multilateral Convention on Mutual Administrative Assistance in Tax Matters to bring it in line with the international standard on exchange of information for tax purposes and to open it up to countries that are neither members of the OECD nor of the Council of Europe.
