Electronic Communication between Tax Administration and Tax Entity

The topic chosen for my bachelor work will be "electronic communication between tax administration and tax entity". In theoretical part, I would like to outline the basic concepts related to this form of communication. I would like to introduce development and especially I would like to mention forms of this electronic communication. The work will be most focused on two forms of electronic communication, data boxes and electronic filing. In the practical part, I would like to introduce how these two services are used and I would tried to show in detail the whole process for filling tax returns. I would like to give a clear summary of the two named services with their advantages and disadvantages. Primarily, the work will based on own experiences, then I contact other users of electronic communications (mainly through questionnaires) and the next source of information will be for me the local tax office. The work should be written in simple and understandable manner, so that it could help those tax entities, who until now have no information for this issue
