The investigation into the club’s prior transfer dealings led to a 15-point deduction for Juventus, according to the Italian football association (FIGC).
The Serie A powerhouses were charged with manipulating their financial statements to make fictitious gains from club transfers.
Juventus was in third place prior to the penalty, which will move them down to tenth.
Former club president Andrea Agnelli and vice-president Pavel Nedved both resigned from the board of directors in November.
Juventus has said they will appeal the ruling and has denied doing anything wrong.
The club issued a statement saying they “await the publication of the reasons for the decision” but have already begun filing an appeal with the Italian Olympic Committee’s Sport Guarantee Board (CONI).
The FIGC’s punishment is more severe than the nine points that the prosecutors had asked for.
