The IMF Working Papers series is designed to make IMF staff research available to a wide audience. Almost 300 Working Papers are released each year, covering a wide range of theoretical and analytical topics, including balance of payments, monetary and fiscal issues, global liquidity, and national and international economic developments.
We review the current state of the West African Economic and Monetary Union's tax coordination framework, against the main objectives of the WAEMU Treaty of 1994: reduce distortions to intra-community trade, and mobilize domestic tax revenue. The process of tax coordination in WAEMU is one of the most advanced in the world-de jure at least-, but remains in many areas ineffective de facto. Nevertheless, the framework has, to some extent, succeeded in converging tax systems, particularly statutory tax rates, and may have contributed to improving revenue mobilisation. Important lessons can be drawn from the WAEMU experience, particularly in terms of whether coordination should take the form of harmonization through a top-down approach, or a softer approach of sharing best practice and limiting certain types of tax competition.
