In a citizen centric approach – which became increasingly popular in the last decade – e-government success begins with citizens starting to use e-government systems, solutions, services. In line with this our paper investigates the factors – presented by the technology acceptance literature – influencing e-government service usage, on a large representative Hungarian sample concerning a wide range of B2C public administration services. Our results imply that the Hungarian government can further increase the usage of e-government services by influencing effort expectancy, trust of internet, facilitating conditions, user experience or habits.
