The United Nations Development Programme (UNDP), with whom the Organisation for Economic Co-Operation and Development (OECD) runs a joint secretariat for the Tax Inspectors Without Borders (TIWB) project, works in more than 170 countries and territories, helping to achieve the eradication of poverty, and the reduction of inequalities and exclusion. It helps countries to implement projects, develop policies, leadership skills, share experiences, develop institutional capabilities and build resilience in order to sustain development results.

The OECD is a global economic forum working with 34 member countries and more than 100 emerging and developing economies to make better policies for better lives. Its mission is to promote policies that will improve the economic and social well-being of people around the world. The OECD provides a unique forum in which governments work together to share experiences on what drives economic, social and environmental change, seeking solutions to common problems.

Tax Inspectors Without Borders (TIWB) is a joint initiative of the OECD and UNDP designed to support developing countries to strengthen national tax administrations through building tax audit capacity and to share this knowledge with other countries. Under TIWB, tax audit experts work alongside local officials of developing country tax administrations on tax audit related issues. TIWB aims to strengthen tax administrations by transferring technical know-how and skills to developing countries’ tax auditors, and through the sharing of general audit practices and dissemination of knowledge products.
