E-government provides opportunities to deliver various services more effectively and better serve citizens. In developing countries, e-government initiatives provide services that have been previously inaccessible to their citizens. However, e-government initiatives in developing countries are still in their infancy and face a wide range of barriers that restrict wide-spread use. Like many other developing countries, Pakistan has a low level of e-government services adoption. Previous research has investigated e-government services in developing countries from the organizational perspective. However, the research stream suffers from an absence of studies that have investigated e-government from a citizen’s perspective. The success of e-government services depends on government support as well as on citizen’s adoption. This paper aims to fill this gap by exploring the challenges and barriers of e-government services from the user’s perspective. In this study, an amended version of the UTAUT model is used to investigate the factors influencing the uptake of e-government services in Pakistan. The results show that the factors influencing the adoption of e-government services in Pakistan are related to ease of use, usefulness, social influence, technological issues, lack of awareness, data privacy, and trust. Implications for e-businesses and government policy decision makers are also considered in this study.
