The notion of implementing a global tax on the assets of billionaires has been gaining traction among certain members of the G20 group of advanced economies. However, the Biden administration has made it clear that such a proposal does not have its support. U.S. Treasury Secretary Janet Yellen, in an interview with The Wall Street Journal, emphasized that while the U.S. is in favor of progressive taxation where the wealthy pay a larger share of their income, a common global arrangement for taxing billionaires is not something the U.S. can endorse.

U.S. Stance on Progressive Taxation

Yellen reiterated the U.S. commitment to progressive taxation. This tax system ensures that individuals with higher incomes contribute a larger proportion of their earnings compared to those with lower incomes. However, the concept of a globally coordinated tax on billionaires, with the proceeds redistributed in some manner, is not aligned with U.S. policy. Yellen stated, “That’s something we can’t sign on to,” signaling a firm stance against international tax coordination efforts for billionaires.

Global Support for the Billionaire Tax

Despite the lack of U.S. support, the proposal has found backing from some major economies, including France and Brazil. The idea behind a global billionaire tax is to curb the ability of the ultrawealthy to avoid taxes by moving their assets across borders or into tax havens. Taxing wealth rather than income would address the issue of billionaires using investment strategies to grow their wealth while generating minimal taxable income.

Arguments for a Global Wealth Tax

At the G20 finance ministers meeting in February, economist Gabriel Zucman, director of the EU Tax Observatory, presented evidence that the current global taxation system for billionaires is regressive. This means that the effective tax rate for billionaires is lower, sometimes significantly, than that for average taxpayers. Zucman argued that the best way to address this inequality is through international coordination, establishing a common minimum standard for taxing the ultrawealthy.

Zucman’s organization estimated that a 2% annual tax on the wealth of about 3,000 billionaires worldwide could generate approximately $250 billion in revenue each year. Such a tax would help prevent billionaires from relocating to low-tax regions and exert pressure on tax systems globally to maintain fairness.

Moral and Economic Justifications

Prominent voices at the G20 meeting, including MIT professor and Nobel Prize-winning economist Esther Duflo, supported the 2% tax and emphasized its importance in assisting poorer nations struggling with climate change. Duflo highlighted that wealthy individuals and corporations profit globally, including from poor countries, and contribute significantly to climate change. She framed the obligation of wealthy nations to help poorer countries as a “moral debt,” advocating for the ultrawealthy to pay their fair share.

Brazilian Finance Minister Fernando Haddad echoed these sentiments, arguing that international taxation is crucial for economic justice and addressing global inequality. He noted that inequality is rising, and the Sustainable Development Goals are becoming more challenging to achieve without significant international cooperation. Haddad stressed that without global cooperation, national efforts to tax the wealthy would be limited.

Support from France and the IMF

French Finance Minister Bruno Le Maire expressed strong support for the global tax on billionaires, emphasizing its efficiency and justice. He asserted that each individual should contribute their fair share. Additionally, Kristalina Georgieva, Managing Director of the International Monetary Fund (IMF), highlighted the disparity in tax burdens, where in many countries, the rich pay fewer taxes than the middle class and the poor. She called for closing tax loopholes and preventing tax evasion through international agreements that facilitate tax information sharing.


The proposal for a global tax on billionaires aims to address the disparity in tax burdens and ensure that the ultrawealthy contribute fairly to global economic systems. While it has garnered support from several major economies and international organizations, the lack of endorsement from the U.S. presents a significant challenge to its implementation. The Biden administration’s stance reflects a preference for progressive taxation at the national level rather than a coordinated global approach. The debate over taxing the ultrawealthy highlights the broader issue of economic inequality and the need for international cooperation to create fair and effective tax systems.
