Tax Cooperation Policy Brief 21, November 2021
Streamlining the Architecture of International Tax through a UN Framework Convention on Tax Cooperation
By Abdul Muheet Chowdhary and Sol Picciotto
The architecture of international taxation at present is fragmented among multiple institutions. The UN Tax Committee, the OECD/G20 Inclusive Framework on Base Erosion and Profit Shifting (BEPS) and the Global Forum on Transparency and Exchange of Information for Tax Purposes are some of the key institutions which set multiple and overlapping international tax standards. The lack of a genuinely global international tax body has long been a lacunae in the international economic system and a disadvantage for developing countries, who are unable to participate in international tax standard setting as full and equal participants. This has been borne out most recently by the Two Pillar Solution for taxing the digital economy that has come from the OECD/G20 Inclusive Framework. The G-77’s renewed demand for a global tax body shows the issue continues to remain a priority for developing countries.
This Policy Brief provides a way for bringing the existing plethora of institutions under unified, universal and democratic control through a UN Framework Convention on Tax Cooperation (UN FCTC). This idea builds on the long-standing idea of a UN Tax Convention, which has also been recommended by the UN FACTI Panel. A UN FCTC would function similarly to the UN Framework Convention on Climate Change (UN FCCC), through a Conference of Parties (COP) which would give the existing institutions such as the UN Tax Committee and Inclusive Framework mandates to work on. In this regard, it would replace the narrow mandates of the OECD and G20 with mandates coming from all the Parties to the UN FCTC, which could be all countries, both developed and developing. A UN FCTC thus provides a practical and realistic way forward for a genuinely universal, intergovernmental framework for international tax rule making under the auspices of the United Nations.
