Over the last five years, in response to changing global market dynamics and business needs, Deloitte has commissioned biennial market research with global tax decision makers from the largest multinational businesses. Since 2010, three independent research studies into the management of tax have been conducted, culminating with completion of the most recent study in December 2014. With over 1,000 organizations now surveyed, our body of findings provides objective market insight into the global management of tax.
