Taxing the People, Not Trade: The International Monetary Fund and the Structure of Taxation in Developing Countries

Strengthening fiscal capacity in low- and middle-income countries is essential for achieving sustainable development. The International Monetary Fund—the world’s premier agent of fiscal policy reform—has taken a front-stage role in this process, promoting a model of tax policy that favors broad-based consumption taxes and discourages trade taxes. This article investigates the links between IMF-mandated tax reforms and the evolution of tax revenues. Using novel measures of tax-related conditionality and disaggregated data on revenues, our analysis shows that IMF interventions are significantly related to changes in tax structure. In particular, IMF programs increase revenues derived
from goods and services taxes, but decrease revenues collected from trade taxes. Results for personal and corporate income taxes are inconclusive. These findings have important implications for debates on the role of the IMF in developing countries.
