The new 15% global minimum tax that took effect this year is turning out to be compliance beast. The tax, which is part of an international tax deal agreed to by more than 140 countries in 2021, contains a slew of new technical terms, complex rules, and hundreds of pages of administrative guidance. Now, some of the largest accounting firms in the world have been tasked with interpreting these rules, educating their clients, and building complex data systems to help multinational companies calculate their global minimum tax bills. In this week's episode of "Talking Tax," reporter Lauren Vella sits down with Danyle Ordway, principal of tax technology and data analytics at Ernst & Young LLP, to talk about how the firm is helping clients adapt to the new levy.
