Electronic government (e-government) has been a policy issue for several nations since 1990s. Although e-government is vital due to its importance inenhancing efficiency in public sector services, itsimplementation has manychallenges. This study, therefore, aimed at examining the administrative features and users’ attributes as far as technological aspects are concerned, for e-government implementation. Data wascollected by using structured questionnaires served to Customs Staff and Tax Practitioners in DaresSalaam Region. This data included technological aspects (e.g.ICT infrastructure and support); user’s attributes (e.g. education levels); and administrative aspects in ICT regulations. Itwasanalysed quantitatively using descriptive statistics,factor analysis and finally, thestudy hypotheses were tested using structural equation modelling. The results show that the developed model was supportive as users’ attributes and administrative aspects were bothpositively related to success of technological aspects relevant for e-government implementation. Consequently, governments need to give attention to administrative issues of ICT policies, regulations,as well as people-related matters such as ICT knowledge for the success of technologicalaspectsuseful in e-government operations. However, the research addressed concerns withinTanzania’s context, one of the developing countries; and such findings might not be generalised. It would be very informative if the study was replicated in other developing countries, to determine the pattern of influence of administrative characteristics and users’ attributes on e-government.
