Talks over a global tax deal are looking to a Group of 20 finance leaders meeting this week for progress on a stalled plan to reallocate taxing rights on large multinational companies. The so-called "Pillar 1" arrangement, part of a 2021 global two-part tax deal, aims to replace unilateral digital services taxes (DSTs) on U.S. tech giants including Alphabet's Google, Amazon and Apple through a new mechanism to share taxing rights on a broader, global group of companies.
