According to Swiss Ramble, a blog mostly dedicated to the business of soccer, Bayern's revenue rose from €223 million ($290 million) in 2007 to €368 million ($479 million) in 2012.
Dortmund's increase over the same period, €99 million ($129 million), put it second, with Goetze's sale sure to improve the numbers further.
Dortmund's pre-tax profits in 2011/2012 rose to 37 million euros, said SwissRamble, eight years after it nearly went bankrupt.
Hoeness, who won three of the biggest prizes in soccer as a player -- the World Cup, European Championships and European Cup -- told tax authorities in January about a private bank account he held in Switzerland.
"Through my tax adviser I turned myself in to tax authorities in January 2013. It was in relation to a Swiss bank account of mine," the Bayern president told Focus magazine.
The amount hasn't been disclosed, though Bild reported that Hoeness has already paid back €6 million ($7.8 million).
"Tax evasion is without any doubt a serious crime and there can be no justification at all for tax evasion," Chancellor Angela Merkel spokesman Seibert told a news conference on Monday.
"Uli Hoeness has disappointed many people in Germany, including the Chancellor."
Reporters were barred from asking questions about Hoeness' tax affairs at Bayern's press conference ahead of the Barcelona clash.
The 61-year-old Hoeness has been a key figure in helping to turn Bayern Munich into a global powerhouse that not only wins titles with established stars but nurtures young talent, similar to Barcelona.
