US Ends Pillar One Tax Talks, Digital Economy Tax Rules Uncertain
The United States has officially withdrawn from Pillar One of the OECD's global tax reform, effectively ending negotiations for a new international tax framework for digital companies.
NEW YORK – U.S. Treasury officials have declared the "two-pillar global tax reform solution" dead, specifically confirming the withdrawal from Pillar One. This statement signals the end of international negotiations aimed at overhauling how multinational corporations, particularly in the digital economy, are taxed across borders.
The Pillar One initiative, part of a broader OECD/G20 framework agreed upon in October 2021, sought to address the tax challenges posed by digitalization. Its core objective was to reallocate taxing rights to market jurisdictions where large companies generate significant revenue, even without a physical presence. This was intended to replace unilateral measures like Digital Services Taxes (DSTs) implemented by various countries.
A key tenet of Pillar One was the "Amount A" formula, which would grant market countries a share of the residual profits of the largest and most profitable multinational enterprises (MNEs) groups, typically those with global revenues exceeding €20 billion and profit margins above 10%. A portion of profits exceeding a 10% return on revenue would be reallocated based on where consumers are located.
The failure of Pillar One is largely attributed to the inability to secure domestic approval in the United States. As home to many of the world's largest tech firms, U.S. participation was critical for the framework's success. However, significant political opposition in Congress, concerned about potential revenue losses and the impact on U.S.-headquartered companies, prevented the necessary Senate ratification. The change in U.S. administration following the 2025 elections ultimately led to the formal withdrawal from the Pillar One commitments.
