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] The new system should automatically and systematically transmit all relevant information. The agreement has been informally referred to as GATCA (the global version of FATCA), but “CRS is not just an extension of FATCA.” [4] OECD initiatives have made it clear that the international community will not tolerate harmful tax practices in tax havens that deplete countries` tax bases. This is done naturally when the people of this country invest in tax havens. The hope is that the implementation of the MCAA and the various sanctions and sanctions will lead to the decline of many circumvention measures in practice. On 4 June 2015, 61 countries signed the MCAA, with a number of others committed to the agreement to ensure that the majority of the international community strongly supports the OECD in the fight against tax evasion. In August 2020, more than 2,500 bilateral exchanges were activated for jurisdictions that committed to exchange CBC reports, and the first automatic exchange of CBC reports took place in June 2018. These include exchanges between the signatories of the Convention on Multilateral Competent Authorities (CBC MCAA), between eu Member States, in accordance with the EU Directive 2016/881/EU, and between signatories of bilateral agreements for the exchange of competent authorities under double taxation agreements or exchange of tax information, including 41 bilateral agreements with the United States. Legal systems continue to negotiate CBC reporting agreements and the OECD will issue regular updates to clarify things for MNE groups and tax administrations.
