Thank-you University iii ABSTRACT The restructuring of the South African Income Tax system since democracy was used as a case study to analyse the methods used to eliminate international double taxation through the lens of the tax policy principles of equity and neutrality. The theoretical framework used to analyse these methods, when the South African tax system changed from source to residence, was that of considering the equitable basis on which a tax base is chosen; the compatibility of the method of relief with the chosen policy principles of equity and neutrality; and the comparison of inward and outward flows by both residents and non-residents. Town The above approach was applied in analysing three identifiable periods, namely the period prior to democracy in South Africa, the period between the years 1994 and 2000, and post 2000. The analysisCape found that the policy principles of equity and neutrality were not consistently ofapplied to the choice of methods used to relieve international double taxation. Consistent application was undermined by amendments to the Income Tax Act and by the use of anti tax-avoidance provisions to prevent loss to the South African fiscus as a result of an increase in tax planning which resultedUniversity from the broadening of the South African tax base. The findings also indicate that although the methods of relief in the Income Tax Act and in double taxation agreements entered into by South Africa reflect the credit system as the default method, the application and quantification of the relief differs. This thesis adds to the body of literature exploring the policy principles of equity and neutrality, as applied in the context of methods relieving international double taxation and in the context of a recently opened and developing economy. iv The results of the research provide a theoretical basis for future restructuring of the South African income tax system as well as the tax systems of other developing countries, particularly in Africa. They also provide a theoretical basis for considering the policy approach to the taxation of cross border income flows and for choosing the method of relief for international double taxation. This thesis proposes that equity and neutrality should be the over-arching policy principles when considering the methods applied to eliminate double taxation.
