Welcome!

Welcome to the World Tax Database, a project of the Office of Tax Policy Research that has been funded by the Ford Foundation, The Lynde and Harry Bradley Foundation, and the Center for International Business Education at the Stephen M. Ross School of Business at the University of Michigan.

This database has current and historical data on the tax systems of the world. Our aim is to compile on one Internet site all tax data for all countries and all time. Because of the ambitious nature of this endeavor, the database is a work-in-progress. If you have any questions about this project or the data, please contact us at otpr@umich.edu.
