Abstract   The development and implementation of e-government was one of the most relevant and important evolutions for public administration. In recent years, the governments in many countries have made efforts to increase their openness and transparency. E-governance is used, being considered an efficient and effective mean to improve public transparency and reduce corruption. This paper explores the relationship between corruption and e-government in two moments: 2004 (2007) and 2012 in EU and non-UE countries. The analysis is performed on two groups of countries to determine if EU accession has improved the fighting against corruption with e-Government, seeking the practical role of e-Government in changing the level of corruption.
