The global tax landscape is undergoing a major transformation as more than 100 countries have agreed to implement, and to a varying extent have implemented, Pillar Two, which seeks to ensure that all large multinational enterprise groups pay a minimum level of tax on their income, regardless of where they operate or locate their profits.
