text_A: Berlusconi was expected to start serving his four-year prison sentence (reduced to one year), either under house arrest or doing unpaid social community service, in mid-October 2013. In mid-October he informed the court that he preferred to serve the sentence by doing community service. Because of bureaucracy in the legal court system, it was however expected his one-year-long full-time community service would only start in around April 2014. On 19 October, the Milan appeal court ruled that Berlusconi's public office ban should be reduced from five to two years; which was later also confirmed by the Court of Cassation. The court imposed this public office ban, however this did not change the fact that Berlusconi according to the "Severino law" received a ban preventing him from running as a candidate in legislative elections for a prolonged six-year period, which effectively superseded the shorter court imposed public office ban. Berlusconi began his community service at a Catholic care home centre on 9 May 2014, where he is required to work four hours a week for a year with elderly dementia patients.
text_B: Would Berlusconi have needed to have held some other formal employment during the year of his prison sentence, when he worked with dementia patients, in order to receive the Italian equivalent of a W-2 tax form?
YES.
