It’s been a big week for a big idea. On Monday, US Treasury Secretary Janet Yellen advocated for a global minimum corporate tax in her first major public address. US National Security Advisor Jake Sullivan swiftly underscored the message, tweeting that “the U.S. is committed to end the race to the bottom on corporate tax rates and prevent corporations from shifting jobs overseas” as a core piece of its national security strategy. As policymakers around the world consider a global minimum corporate tax, it is important to understand the context behind the concept and how this tax might actually work.
International corporate taxation has long presented a challenge for tax authorities around the world. The emergence of globalization and intangible capital in recent decades has made taxing multinational corporations (MNCs) increasingly difficult, and greater international cooperation is needed to make such taxation more effective. A global minimum tax on profitable MNCs would ensure that a baseline level of revenue is collected from them. Although this tax would not solve all problems related to corporate tax avoidance and evasion, and its design and implementation need careful consideration, it would be an important and helpful step.
