In the face of global outrage at the little or no tax paid by some of the world’s largest multinationals, the G20 appointed the Organisation for Economic Co-operation and Development (OECD) a few years ago to design alternatives to end these abuses. In response, on October 9, 2019, the OECD put forward proposals for a new international tax system that may be imposed on the world in the coming decades. We are talking about a major issue. In the US, for example, 60 of the 500 largest firms — including Amazon, Netflix and General Motors — paid no taxes in 2018 despite a cumulative profit of $79 billion. These misappropriations, often legal, are based on complex arrangements but derived from a simple principle.
