International Corporate Tax Reform

To relieve the pressure on the outdated international corporate tax system, an ambitious reform was agreed at the Inclusive Framework (IF) on Base Erosion and Profit Shifting in 2021, with now 138 jurisdictions joining. It complements previous efforts to mitigate profit shifting by addressing the challenges of the digitalization of the economy through a new allocation of taxing rights to market economies (Pillar 1) and tax competition through a global minimum corporate tax (Pillar 2). This paper concludes that the agreement makes the international tax system more robust to tax spillovers, better equipped to address digitalization, and modestly raises global tax revenues.
