The politics and history of global tax governance

We discuss the history, political determinants and current challenges of global tax governance. We divide the last century into three eras: foundation, during which states built a regime to prevent double taxation using bilateral treaties and soft multilateral coordination; stability, during which this regime failed to adapt to the growth in volume and complexity of cross-border trade and investment capital; finally, the current era of crisis, characterized by politicization, an appetite to reform longstanding institutions, and a willingness to trample over fiscal sovereignty. Existing scholarship explaining this trajectory of change can be organized through well-established interest-based, power-based and ideational accounts. We argue that future research could build on this existing scholarship by reorienting in three different ways: from tax competition towards double taxation and tax sovereignty, from the OECD to emerging markets and developing countries, and from mid-level theorization towards the bigger picture of global political economy, of which tax is an intrinsic part.
