Marc Sorrentino, 38, faces up to three years for aiding in the preparation of a fraudulent tax return. Mike Sorrentino was charged with two counts, as well as failure to file a tax return for 2011, when he allegedly earned almost $1.96 million.
As The Blast first reported, Sorrentino faces up to 15 years in prison.
Prosecutors accused The Situation and his brother, Marc Sorrentino, in 2014 of evading taxes on income of almost $9 million, but the men's plea deals in New Jersey are largely silent on numbers. Sorrentino initially rejected a plea deal offer from prosecutors but he seemed to have had a change of heart. He also claimed numerous personal expenses, including luxury cars and clothing, as business write-offs, according to court documents.
Additional charges were filed past year when federal prosecutors announced a superseding indictment that accused Mike Sorrentino of tax evasion and structuring funds to evade currency transaction reports. They also faced counts of filing false returns - each of which has a maximum sentence of three years. Marc Sorrentino was charged with falsifying records to obstruct a grand jury investigation.
