A research report submitted to the Faculty of Commerce, Law and Management, University of Witwatersrand, Johannesburg, in partial fulfilment of the requirements for the degree of Master of Commerce (Specialising in Taxation) / South Africa had entered into 97 double taxation agreements (at the time of this study in 2014) with other countries which generally contain an article which authorises the exchange of information between South Africa and the treaty partner. The 2008 global financial crisis re-emphasized the increase in tax planning structures as a result of globalisation to avoid or evade taxes and this highlighted the need for a more transparent tax information sharing platform. Since the 2008 economic crisis, one of the key themes has been the attempts to co-ordinate reform of the global financial system in the pursuit of greater international transparency. Since 2012 Treasury started entering into agreements with various other countries to enhance the transparency of taxes paid by entering into exchange of information agreements: these includes the Bilateral Tax Information Exchange Agreements (TIEA) and the Multilateral Mutual Administrative Assistance (MAA) Agreements and the agreement entered into with the United States of America known as the FATCA (Foreign Account Tax Compliance Act) agreement, signed 9 June 2014. This will support the Double Tax Agreement already in place to enhance the information sharing regime. Government Notices 508 and 509, Gazette number 37778, were published on 27 June 2014 in order to facilitate FATCA compliance in terms of the Tax Administration Act 28 of 2011 (TAA) sections 26, 29 and 30. As FATCA is a new agreement, there is a limited overview of the impact of this exchange of information agreement. This report is to gain insight into the reasons for implementing these agreements, an overview of these agreements and the implications of these agreements, with a specific focus on the newest agreement, FATCA.

Tax authorities are increasingly relying on mutual cooperation with their foreign peers to enforce more effectively their internal tax laws. After the banking scandals of 2008 and the subsequent global financial crisis, the Global Forum on Transparency and Exchange of Information for TaxPurposes has proposed the exchange of information upon request as the fiscal transparency standard. However, some measures adopted by the European Union, previous initiatives from the Organization for Economic Cooperation and Development (OECD) and, above all, the introduction of the Foreign Account Tax Compliance Act (Fatca) by the United States in 2010 have promoted the need to adopt the automatic exchange of information as the new fiscal transparency standard. Automatic exchange of information allows home countries to verify whether their taxpayers have correctly included foreign income, allowing tax authorities to have early warning of possible noncompliance cases. In February 2014, the OECD published its proposal for a new global model of automatic exchange of financial account information. The new global model contains the necessary legal instruments and due diligence and reporting procedures, mainly for financial institutions. / Las autoridades tributarias dependen cada vez más de la cooperación con sus contrapartes extranjeras para administrar más eficazmente sus leyes tributarias nacionales. Luego de los escándalos bancarios de 2008y la crisis financiera global posterior, el Foro Global sobre Transparencia e Intercambio de Información Tributaria ha impulsado el intercambio de información a requerimiento como el estándar internacional en materia de transparencia fiscal. Sin embargo, algunas medidas adoptadas por la UniónEuropea, iniciativas previas de la Organización para la Cooperación y Desarrollo Económicos (OCDE) y, sobre todo, la introducción en 2010 del«Foreign Account Tax Compliance Act» (Fatca) de los Estados Unidos han promovido la necesidad de adoptar el intercambio automático de informacióncomo nuevo estándar de transparencia fiscal internacional. El intercambio automático de información le permite a las jurisdicciones de la residencia verificar si sus contribuyentes han incluido correctamente las rentas obtenidas en el exterior, permitiéndole a las autoridades tributarias contar con alertas tempranas de posibles casos de incumplimiento. En febrero de 2014, la OCDE publicó su propuesta para un nuevo modelo global de intercambio automático de información aplicable a las cuentas mantenidas en entidades financieras. El nuevo modelo global contiene los instrumentos legales necesarios y los procedimientos de debida diligencia y reporte principalmente para las instituciones financieras.
