Harry Redknapp did not tell his accountant or bank about an offshore account for years, jurors have heard, the BBC reported.
On the second day of the trial on Tuesday the jury heard that the Tottenham boss kept his Monaco account a secret from his accountant for four-and-a-half years and from his bank relations manager for five years and eight months, the BBC added.
Redknapp is accused of receiving secret payments from former Portsmouth chairman Milan Mandaric, 73, while he was manager at the south coast club.
Redknapp only revealed he had the Monaco-based account after being asked by a Premier League inquiry, Southwark Crown Court heard.
Mandaric and Redknapp, 64, deny charges of cheating the public revenue.
Previously, jurors heard how Redknapp received a percentage of net profit from transfers during his time at Portsmouth, the BBC said.
