Intervention (Public) The intervention consists of using the change in the accompanying mechanisms that taxpayers have to comply with their obligations. Consequently, three types of communications will be sent to three randomly selected groups. Each communication has a different level of information. The first one only reminds the date of compliance with income tax obligations. The second one also includes additional content on the implementation of a new accompanying interface and the specific date. The third letter includes, in addition to the content of the second letter, a set of images related to the new platform. These letters will be sent before the due date of the tax liability and the implementation of the new accompanying technology.
