The OECD-Council of Europe Convention on Mutual Administrative Assistance in Tax Matters, amended by the 2010 protocol, took effect in the Philippines on 1 May 2025.
The Multilateral Convention on Mutual Administrative Assistance in Tax Matters (“the Convention”) was developed jointly by the OECD and the Council of Europe in 1988 and amended by Protocol in 2010. It is currently the most comprehensive multilateral instrument available for all forms of tax co-operation to tackle tax evasion and avoidance.
The Convention facilitates a wide variety of forms of administrative assistance. These include all forms of exchange of information, namely exchange of information on request, automatic exchange of information, spontaneous exchange of information, as well as simultaneous tax examinations, and tax examinations abroad, the assistance in recovery of tax claims, and assistance in the service of documents.
The Convention applies from 1 January 2026 but may apply earlier between signatories if agreed, and to any period concerning criminal matters.
