The Situation lands in deeper trouble than Seaside Heights police ever gave him on "Jersey Shore."

Mike Sorrentino and his brother Marc face federal charges of avoiding taxes on $8,900,000 worth of promotional income dating back to 2010.

They're charged with one count of conspiracy to defraud the United States. Marc faces three counts, and Mike two, of filing false tax returns from 2010 through 2012. The Sitch is also charged with failing to file any tax return at all in 2011, when prosecutors say he raked in $1,995,757.

Their arraignment is scheduled for October 6 in Newark.

If they go to trial and are convicted, the brothers risk up to five years in prison and fines as high as $250,000 for the conspiracy and false-filing counts. Mike Sorrentino's charge of failing to file a return carries a sentence of a year behind bars and a possible $100,000 fine on conviction.

"According to the indictment, Michael and Marc Sorrentino filed false tax returns that incorrectly reported millions made from promotions and appearances," said U.S. Attorney Paul J. Fishman in a prepared release.

"The brothers allegedly also claimed costly clothes and cars as business expenses and funneled company money into personal accounts. The law is absolutely clear: telling the truth to the IRS is not optional."
