MUNICH: The tax debt run up by Uli Hoeness in his illicit Swiss bank account was at least €27.2m – if not much more – rather than the €3m he paid in January, the second day of his trial was told.

Tax inspector Gabriele Hamberger was giving evidence in Munich hours before Bayern – of which Hoeness is all-powerful president – hosted Arsenal in the UEFA Champions League.

She said that Hoeness and his advisers had repeatedly stalled on submitting documentation and that even the paperwork provided may not have told the full story. They had missed four deadlines between February and December last year.

Hamberger said that it was not clear how much profit on share dealings Hoeness may have reinvested between 2003 and 2009. Hoeness himself had conceded on Monday, the trial’s opening day, that he probably owed around €18.5m.

Hamberger took the court through a large bundle of files including a “blue folder” from the Swiss bank Vontobel. Some €70m could have been allowed in tax-free profits but what should have been declared was uncertain.

Finally, in February, Hamberger said that Hoeness had provided two USB flash drives with 52,000 pages of data. However the files could not be opened by the investigators. A reformatted USB stick was provided at the start of last week with the startling, much larger sums.

After earlier uncertainty about the length of the trial, a verdict is still expected on Thursday.
