The current paper aims to propose a framework for investigating the level of acceptance of the users for e-government services. The proposed model consists of two main independent variables. The first factor is the perceived usefulness with two-constructs, namely: perceived usefulness and perceived ease of use. The second independent variable is trust, which has three sub-constructs: perceived risk, perceived privacy and perceived security. The proposed model hypothesizes that these variables have a positive effect on the users' acceptance for egovernment services. The proposed model also hypothesizes that knowledge technology has a positive effect on the relationship between the independent and dependent variables. This model could help to understand the level of acceptance of the users for e-government services, especially that it has focused on both positive and negative factors that might influence the users' acceptance of e-government services.
