TAX TRANSPARENCY: THE NEW “NORMAL”. This article looks at the how governments and business will have to learn to operate in an environment which is characterized by increased tax transparency and a great focus by civil society and politicians on the taxes paid by multinational enterprises and high net worth individuals. It also discusses the outcomes from the G20 led Base Erosion Profit Shifting initiative and the debate over whether multinational enterprises are paying their fair share of the tax burden. It begins by looking at the economic environment which has shaped these initiatives and then examines what have been the main drivers of these changes. A concluding section sets out what are some of the implications for Brazilian multinational enterprises and the Brazilian Revenue Service. Jeffrey Owens.
