Tanzania government has been making efforts to provide its information and services through internet. However, e-government adoption has been quite slow. Few publications explore e-government adoption in Tanzanian context; therefore, the purpose of this paper is to assess factors that influence citizen adoption of e-government in Tanzania. Design/methodology/approach- A survey was administered to elicit factors for e-government adoption in Tanzania. Findings- The results of multiple linear regressions indicate that social influence and system quality significantly influence e-government adoption in Tanzania.Research limitation/implications- In light of these findings, researchers should conduct a similar study using other different models of e-government adoption, in order to identify more factors that influence e-government adoption in Tanzania. Practical implications- Policy makers and e-government project teams should consider these factors to facilitate e-government adoption within the country.
