About TJNA

The Tax Justice Network-Africa (TJN-A) is a Pan-African initiative and a member of the Global Alliance for Tax Justice. Launched in January 2007 during the World Social Forum (WSF) held in Nairobi, TJN-A promotes socially- just, accountable and progressive taxation systems in Africa. It advocates for tax policies with pro-poor outcomes and tax systems that curb public resource leakages and enhance domestic resource mobilisation.
