As part of the wider economic stimulus packages to respond to the second wave of COVID-19, governments continue to temporarily defer the collection of social security contributions (SSC), or to exempt from or reduce the contribution payments of some population groups. To date, 68 countries have introduced at least one of these measures (ISSA Coronavirus Country Measures Monitor). An April 2020 communication from the European Commission supported these as a “valuable tool to reduce the liquidity constraints of undertakings and preserve employment” during the COVID-19 crisis (EC 2020a).
