The AC Milan owner has been found guilty of evading taxes which were meant to be paid for television rights his company Mediaset had purchased
The conviction is relating to television rights his company, Mediaset, purchased, and Berlusconi will carry out his community service in a home for the elderly.
The 77-year-old would have been liable to spend four years behind bars over the case, but three of them were covered by amnesties.
The former Prime Minister is too old to go to prison under Italian law and the alternative to community service would have been house arrest.
Berlusconi's conviction now means that he will not be able to stand in European elections next month, or to vote for the party of his choice.
