Just and resilient societies depend on an adequate public funding base to provide important public goods, such as health care and education. The COVID-19 pandemic crisis has put a stark spotlight on this: Strong public health systems are an important pre-requisite for successfully dealing with the medical consequences of the pandemic, and fiscal stimulus packages will play an important role in stabilising economies. However, in recent years there has been an erosion of the public funding base in many countries, as the globalisation and digitalisation of value creation was accompanied by profit shifting and tax avoidance. What can the G20 do to support tax systems for just and resilient societies? Will the OECD led initiative on Base Erosion and Profit Shifting come to a successful conclusion in 2020, as envisaged by G20 leaders? How can progressive wealth taxes contribute to more equitable societies?
