The FINANCIAL — Much of the architecture for global tax rules is a product of postwar institutions, context and culture. The world is now a very different place so how to agree and enforce rules and regulations in a globally-connected system in a way that is fit for our global future? A new publication and unique event seek to address this difficult question. It is now obvious that our tax systems, designed in the 20th century, need to adapt to today’s realities. A world of full employment, with one job for life in an analogue national economy is fast giving way to flexible working in a complex digitally-driven economy that flows across borders – where everything is connected to everyone; these and other attributes of the modern world have major implications for taxpayers, tax systems and societies around the world. KPMG International, as part of its ongoing global Responsible Tax project in partnership with Jericho Chambers, has brought together a broad array of voices on this subject in a new publication, What to Tax?, launched today in London at a special idea-exchange. Both the event and the publication seek to reimagine what responsible tax looks like in an increasingly digital, global environment. The responsible tax idea exchange brings together nearly  different voices for interactive discussions and hands-on workshops. With participants representing a wide range of different perspectives from businesses to NGOs to academia to policymakers.
