Tax and Development Case Studies


This series of tax and development case studies in selected countries demonstrates how governments in developing countries are addressing tax avoidance and evasion, assisted by the tools and capacity building services which the OECD and the Global Forum on Transparency and Exchange of Information for Tax Purposes carry out with the crucial support of their donors and partner organisations. The case studies cover different regions, income groups and topics - from tax base erosion and profit shifting (BEPS) and tax transparency to the joint OECD/UNDP Tax Inspectors Without Borders initiative. This series complements OECD's recent reports on tax and development, such as the Tax Co-operation for Development: Progress Report, and the Tax Inspectors Without Borders Annual Report 2021.
