A basic tool to assess tax administration strength in emerging Europe

Large tax compliance gaps, together with the need to generate additional tax revenue have put a premium on tax administration reform in emerging Europe. The key features of an efficient tax administration are well established, but an objective assessment of the relative strengths and weaknesses of tax administrations have been lacking. This paper proposes a simple index of tax administration strength, based on objective indicators reflecting key organizational and operational aspects of revenue administrations relative to international best practice. A diagnostic test is then conducted to assess the performance of the proposed index in its ability to predict variations in tax collection efficiency in emerging Europe.
