Mandaric, along with Tottenham Hotspur manager Harry Redknapp, already faced two counts of cheating the public revenue, while Storrie had already been charged with tax evasion over a 2003 transfer deal.
A hearing at Southwark Crown Court, which the men did not attend,was told Mandaric and Storrie have now also been charged with evading tax in relation to midfielder Eyal Berkovic's termination fee and will appear at City of Westminster Magistrates' Court on June 17 and June 9 respectively.
The pair are accused of making an offshore payment to terminate Berkovic's contract on which no tax was declared or paid, the Press Association reported.
The team has been in turmoil this season. With debts of more than £199 million Portsmouth became the first Premier League club to go into administration and were relegated after finishing bottom of the league.
