The Common Information Standard (SIR) is the result of efforts by G20 countries to develop a global standard for automatic information exchange (AEOI). To facilitate the EEA, the Organisation for Economic Co-operation and Development (OECD) has developed IRSs in collaboration with G20 countries and in close cooperation with the EU and other stakeholders. The aim of the AEOI is to improve transparency in the fight against tax evasion and, therefore, to protect the integrity of the tax systems of the participating jurisdictions. Automatic exchange of information (AIA) is the exchange of information between countries without having to ask. In May 2014, 47 countries tentatively agreed on a «common reporting standard,» officially designated as the standard for the automatic exchange of financial account information: an automatic exchange of information on residents` assets and income in accordance with the standard. [2] Among the 34 OECD countries, Argentina, Brazil, China, Colombia, Costa Rica, India, Indonesia, Latvia, Lithuania, Malaysia, Saudi Arabia, Singapore and South Africa. [2] Since October 2014[update], 51 countries have signed the Multilateral Competent Authority Agreement (MCAA) to automatically exchange information on the basis of Article 6 of the Convention on Mutual Tax Assistance. [6] In summary, some agreements already exist between countries, but the standard annual report will begin from 2017 and will spread in 2018. This means that many tax offices currently have access to information about non-residents, but this is an application procedure. The AIA is an international standard that governs how tax authorities in participating countries exchange data on taxpayers` bank and deposit accounts. The aim is to make tax evasion impossible. The G20 countries, the OECD and other major financial centres, which together have more than 100 countries, have committed to implementing the AIA.
The United States, which implements its own standard (FATCA), is an exception. On 29 October 2014, 51 legal systems, 39 of which were represented at ministerial level, signed a multilateral agreement on the authority responsible for the automatic exchange of information, on the basis of Article 6 of the multilateral convention.
