STUDY ECONOMY AND FINANCE BUILDING A MOVEMENT The role played by civil society networks in Colombia’s progressive tax reform Alejandro Rodríguez Llach May 2024 Less inequality is necessary for sustainable development and stable democracies. States play an important role in reducing inequality. They do so through pro-­poor spending and regulation, but also through progressive tax regimes. Against the background of a regressive tax reform in Colombia the Red de Trabajo Fiscal(RTF) was born. It is composed of civil society organisations and think­tanks from the country’s most renowned universities. The author illustrates how the RTF managed to form a powerful coalition that succeeded in creating a new political force in Colombia successfully advocating for progressive tax reform.
