The Sorrentino brothers were sentenced Friday morning after having pleaded guilty in January to multiple charges of tax fraud associated with nearly $9million in income.
The reality star appeared in New Jersey federal court on Friday and was given an eight month prison sentence, along with two years of supervised release.
The Sorrentinos were arrested over the tax offenses in 2014.
Sorrentino's attorney had pressed for no jail time, arguing that Sorrentino, 37, played a minor role in how his taxes were prepared and was suffering at the time from addiction to painkillers. Sorrentino pleaded guilty to the charge against him in January and faced a maximum of five years behind bars and a fine of up to $250,000.
The entire cast of Jersey Shore went to Sorrentino's sentencing in a show of support. "People can look at me and say, 'If he can do it, I can'".
Michael Sorrentino admitted that in tax year 2011, he earned taxable income, including some that was paid in cash, and that he took certain actions to hide some of his income to avoid paying the full amount of taxes he owed.
Prosecutors said Sorrentino concealed his cash income by making multiple cash deposits in a single day in amounts less than $10,000 to evade his banks' reporting requirements.
They raked in an estimated $8.9 million between 2010 and 2012 from a range of product endorsements, appearance fees and other projects capitalizing on Sorrentino's wild popularity, according to the U.S. Attorney for the District of New Jersey.
