Registration for students not yet enrolled at the University of Ferrara Per accedere a Domanda On-line occorre preventivamente registrarsi. In order to be able to issue the Certificazione Unica (income tax statement), it is fundamental that you have a fiscal code assigned by Agenzia delle Entrate. If this is not the case, please request one and communicate it to ER.GO through Scrivici by 31/12/2020. Any sanctions of the Agenzia delle Entrate, according to legislative decree 158/2015, on income tax statements rejected because of wrong personal data and/or fiscal code not included in the tax registry, will be charged to the student.
