Tax and Informality

Research Theme

Informality and Tax

While research has historically focused on formal systems of taxation and user fees, there is mounting evidence of the importance of “informal” taxation for average taxpayers in much of Africa. While lying outside of statutory laws, the “tax-like” payments – which include informal user fees, informal contributions to community development projects, and informal payments to both state and non-state officials – impose a significant burden on many taxpayers, while playing a critical role in financing local public goods and services and shaping broader local governance.

Our research aims to map the extent, composition and experiences of these payments, and to understand their implications for livelihoods, fiscal decentralisation, service delivery and broader local governance reform. One strand of our work looks closely at taxation in fragile settings, examining the challenges, risks, and opportunities it presents for peacebuilding, state-building, and citizen engagement.

We have also established a Community of Practice on Informality and Tax, a global network of practitioners and scholars committed to improving both knowledge and policy on how tax authorities engage with informal economies.
