The Tax Justice Network (TJN) is a non-aligned coalition of researchers and activists with a shared concern about the harmful impacts of tax avoidance, tax competition and tax havens. TJN promotes tax justice and tax cooperation and resists tax avoidance, tax evasion and tax competition. It operates on a not-for-profit basis by bringing together organisations, social movements and individuals working towards these goals. In an era of globalisation, the Tax Justice Network is committed to a socially just, democratic and progressive system of taxation. TJN campaigns from an internationalist perspective for a tax system which is favourable for poor people in developing and developed countries, and finances public goods and taxes harmful activities which pollute and cause unacceptable inequality. Our objectives and demands are detailed in the TJN declaration.
