Juventus have been deducted 15 points for the current season by an Italian football court investigating its transfer dealings, the national football federation (FIGC) said on Friday.
With 20 games left to play in this season, Juventus were third in Serie A, 10 points adrift of leaders Napoli.
The points deduction would push them down into mid-table, outside the spots for European competition.
The ruling is tougher than a nine-point deduction a football prosecutor had requested earlier on Friday during a hearing looking at the way Juventus, Italy's most successful club, and a number of other teams dealt with player exchange deals.
The football court also ruled that former Juventus chairman Andrea Agnelli be banned from holding office in Italian football for 24 months.
It also decided on a 30-month ban for Juventus's former sports director, Fabio Paratici, now managing director of football at Premier League club Tottenham.
The club's CEO Maurizio Arrivabene has also been handed a two-year-ban, while former vice-chairman Pavel Nedved has been given an eight month suspension.
Juventus have denied wrongdoing and said their accounting was in line with industry standards.
