About the Tax Justice Network

The Tax Justice Network (TJN) is an independent international network, launched in 2003. It is dedicated to high-level research, analysis and advocacy around international tax and financial regulation, including the role of tax havens. TJN maps, analyses and explains the harmful impacts of tax evasion, tax avoidance and tax competition; and supports the engagement of citizens, civil society organisations and policymakers with the aim of a more just tax system. TJN pursues systemic changes that address the international inequality in the distribution of taxing rights between countries; the national inequalities – including gender inequalities – that arise from poor tax policies; and the national and international obstacles to progressive national tax policies and effective financial regulation.

The Tax Justice Network operates virtually with its legal base in the UK and staff working from home across multiple countries and continents.
