Tax Coordination, Tax Competition, and Revenue Mobilization in the West African Economic and Monetary Union

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.

Tax Policy in MENA Countries: Looking Back and Forward

This paper reviews trends in taxation and revenue in MENA countries over 1990-2012, with a focus on non-resource taxes. On average, non-resource revenues declined slightly, while resource revenues soared. Country experiences vary: rates of main taxes and their revenues tend to be higher in the Magreb than in the Mashreq, except for the value-added tax, where lower rates are associated with equal or higher revenue; most oil producers raise little tax revenues — generally less than 5 percent of GDP — and most have reduced them since the late 1990s. But there are similarities: unlike common experience around the world, income taxes (not indirect taxes) have partially compensated for lost revenue from trade liberalization; revenues from indirect taxes have remained stable; personal income taxes have played an unimportant role as a revenue tool; and fees and stamp duties are significant revenue sources. Looking forward, tax reform challenges will also vary across countries: the Maghreb needs to focus on efficiency-enhancing reforms, especially in capital income and consumption taxes; the Mashreq have some room to increase revenue; and, there are ample opportunities to improve equity and reduce complexity of tax systems in all countries. Finally, the recent decline in oil prices and revenues is a reminder that even resource-rich GCC countries need to lay the basis of a tax system for the future.
