This article examines the factors contributing to the acceptance, adoption, and use of information technologies related to e-government. The objective is to highlight explanatory and predictive factors for the acceptance of specific information technology. The main conclusions of this study validate the general hypothesis that taxpayers' intention to use information technologies influences their technology usage behavior. However, these results are reinforced by the significance of less-publicized determinants such as social influence, facilitation conditions, trust in the governance of digital platforms in e-public administration, expected performance, anticipated effort, while considering technological, individual, and socio-cultural factors. All these elements influence the intention of acceptance and the usage behavior of online public services for Moroccan citizens, and they can be considered as mobilizable levers.
