The Organisation for Economic Co-operation and Development (OECD) is an international organisation comprised of 38 member countries, that works to build better policies for better lives. Our mission is to promote policies that will improve the economic and social well-being of people around the world. Together with governments, policy makers and citizens, we work on establishing evidence-based international standards, and finding solutions to a range of social, economic and environmental challenges. From improving economic performance and creating jobs to fostering strong education and fighting international tax evasion, we provide a unique forum and knowledge hub for data and analysis, exchange of experiences, best-practice sharing, and advice on public policies and international standard-setting. 

The OECD has earned a leading role in international tax issues. The Centre for Tax Policy and Administration (CTPA) is the focal point for the OECD’s work on all taxation issues, both international and domestic, and it works to advance the Strategic Orientations of the Secretary-General, ensuring impact of the OECD tax work in the international governance architecture. The CTPA collaborates with other parts of the Organisation on issues such as the digitalisation of the global economy, tax and climate change, tax and inclusive growth, and the impact of taxation on labour markets and several other multidisciplinary projects. The CTPA also provides analytical support to the OECD’s Committee on Fiscal Affairs, which consists of senior tax policy and administration officials from OECD countries, Associate and Partner countries and other international and regional tax organisations. It supports the work of the Inclusive Framework on Base Erosion and Profit Shifting (BEPS), with more than 145 member countries and jurisdictions, and the Inclusive Forum on Carbon Mitigation Approaches.  It also has a comprehensive outreach and capacity building programme supporting the development of tax systems in developing countries. Through its work, the CTPA enhances the OECD’s global role in standard-setting, building knowledge, communicating with the world and interacting with governments and stakeholders from around the world to inform and influence policy making in the tax area. 

The Country Tax Policy Unit is part of the CTPA’s Tax Policy and Statistics Division, which is an inter-disciplinary team of economists, statisticians and policy analysts who are focused on providing internationally comparable tax statistics and delivering high-quality economic analysis and tax policy advice. The Country Tax Policy Unit focuses on country-specific tax policy analysis and brings together the different streams of tax policy work in a comprehensive manner.  

CTPA is looking for several Tax Policy Economists to contribute to the work on tax policy in OECD member and non-member countries, including domestic resource mobilisation through tax reform in developing and emerging economies. The Tax Policy Economist(s) will work on a broad range of topics, including general country tax policy analysis and country advice, tax expenditures and incentives, tax and informality, social protection financing, presumptive tax regimes, health taxes, and other taxes and tax policy topics in relation to inequality and economic growth in countries around the world. The Tax Policy Economist(s) will contribute to the work on empirical tax policy analysis to assess country tax systems and present tax policy reform recommendations.
