The 76-year-old was originally handed a four-year jail sentence and €10 million fine on Friday, for his part in a tax fraud scandal.
Berlusconi, along with 10 others, was on trial after it was alleged that the defendants were involved in a scheme to purchase American movies for his company, Mediaset, through an offshore firm and had failed to properly declare payments so as to avoid taxes.
It was also claimed that Berlusconi had re-licensed the films, and pocketed the difference, making the Milan supremo some €250m.
The Italian has been involved in a number of legal procedures to do with his business ventures, but has either been cleared, or the cases have been dropped due to time constraints.
Berlusconi, who was not in court on Friday to hear the verdict, served as Prime Minister of Italy between 1994 and 1995, 2001 and 2006, and 2008 and 2011, but recently announced that he would not be running for a fourth term.
