During recent years, new doubts about the effectiveness of international aid have emerged. One of the arguments employed to justify this sceptical view is that aid can hinder tax effort in developing countries. Nevertheless, empirical research on the aid-tax nexus is inconclusive and it shows some shortcomings in the tax database employed and in the variables considered in the estimation. The main goal of this article is to overcome these shortcomings. The main results are twofold: i) income distribution is a crucial determinant of tax revenues; and ii) once income distribution is taken into account, aid shows no significant impact on tax revenue; not even when we control for institutional quality.
