RIO DE JANEIRO, Brazil — Talks over a global tax deal are continuing well past a June 30 deadline and governments are now looking to a Group of 20 (G20) 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 US tech giants including Alphabet's Google, Amazon.com and Apple through a new mechanism to share taxing rights on a broader, global group of companies.
