In the result of a probe into the team’s prior transfer activities, Juventus has been docked 15 points.
Fabio Paratici, an ex-director of Juventus who is currently at Tottenham, received a two-and-a-half-year suspension from Italian football, the Italian Football Federation (FIGC) announced on Friday.
The ban for Paratici includes a request for an extension to encompass UEFA and FIFA activities, which could have significant repercussions for Premier League team Spurs.
Andrea Agnelli, a former Juve executive, has also been barred from holding any positions in Italian football for the subsequent two years.
It has been widely reported the decision is likely to be appealed by Juve.
The Bianconeri had been third in Serie A, but have now dropped to 10th – 12 points off the Champions League places – as a result of the punishment.
Turin Public Prosecutor’s Office had been seeking a nine-point deduction following a hearing earlier on Friday.
But the FIGC went with a harsher punishment after Juve were found to have used transfers to artificially boost their balance sheet.
The sanction comes on the back of chairman Agnelli, vice-president Pavel Nedved and the rest of the Bianconeri’s board resigning en-masse last year.
That came in the wake of an investigation being launched into financial violations during their time in charge.
A separate ruling made last year acquitted Juve and other clubs of their financial conduct within Serie A, with a case centred on player values in exchanges and transfers.
But football prosecutors reopened the case against Juve after seeking new documents collected by public prosecutors in Turin surrounding the club’s conduct.
Juve have denied any wrongdoing, while lawyers claimed prosecutors had not brought enough in to reach the adequate threshold for a new ruling.
The 36-time Italian champions are next in action on Sunday at home to Atalanta, in what was set to be a potentially crucial clash in the race for Champions League qualification.
