The Automatic Exchange of Information (AEOI) portal provides a comprehensive overview of the work the OECD and the Global Forum on Transparency and Exchange of Information for Tax Purposes in the area of the automatic exchange of information, in particular with respect to the Common Reporting Standard.


As the world becomes increasingly globalised and cross-border activities become the norm, tax administrations need to work together to ensure that taxpayers pay the right amount of tax to the right jurisdiction. A key aspect for making tax administrations ready for the challenges of the 21st century is equipping them with the necessary legal, administrative and IT tools for verifying compliance of their taxpayers. Against that background, the enhanced co-operation between tax authorities through AEOI is crucial in bringing national tax administration in line with the globalised economy.

  • Self-certification formsThe Business and Industry Advisory Committee to the OECD (BIAC) has drafted the following self-certification forms and has requested the OECD to make these forms available on the AEOI Portal to assist with the implementation of the CRS. The OECD has not approved the forms and neither the OECD nor BIAC regard them as mandatory or as best practice documents. They serve only to illustrate how financial institutions may consider requesting customer information from their accountholders. Financial institutions should consult their advisers to ensure their CRS-related operations, including the self-certification forms collected from accountholders, comply with all applicable national laws. BIAC is an independent international business association devoted to giving the OECD business perspectives on a broad range of global policy issues.
