How Siew Moon is building a better working world
“As the corporate landscape becomes more complex amid globalization and digitalization, the global tax environment looks to bring even more uncertainty — and perhaps challenges — to businesses. Together with EY tax policy and controversy professionals and others across the tax functions, using extensive EY experience in working with governments and companies, I help EY clients to prevent, manage and resolve their tax controversies.”
