Tax capacity—the policy, institutional, and technical capabilities to collect tax revenue—is part of a deeper process of state building that is essential for achieving the sustainable development goals. This Staff Discussion Note shows that developing countries have made some progress in revenue mobilization during the past decades. However, much more is needed. We find that a staggering 9 percentage-point increase in the tax-to-GDP ratio is feasible through a combination of tax system reform and institutional capacity building. Achieving this calls for a holistic and institution-based approach that focuses on improving policy, administration and legal implementation of core taxes. The note offers practical lessons and guidance, based on IMF capacity building experience in this area.
