He was found to have diverted over $567,000 of Mystic Pizza receipts into various bank accounts from 2006 to 2010, along with paying over $162,000 to two 'no-show' employees who did no work for the pizzeria.
Over $330,000 of that money was diverted into his family's accounts.
He pleaded guilty to one count of tax evasion and one count of structuring financial transactions on March 31.
Zelepos will report to prison on Oct. 30.
