Boston – The operator of a restaurant and apartment building was charged today for allegedly aiding the filing of false tax returns.
Demetrios Pseudoikonomou of Belmont has been charged with eight counts of aiding the filing of false tax returns. Pseudoikonomou was arrested today and released on conditions following an initial appearance in federal court in Worcester.
According to the charging documents, Pseudoikonomou operated a restaurant and apartment building in Boston. It is alleged that between approximately 2018 through 2023, Pseudoikonomou deliberately failed to report more than $1.6 million in gross receipts and rental income for these businesses to the Internal Revenue Service (IRS). As a result, Pseudoikonomou allegedly avoided paying more than $520,000 in federal income taxes.
It is further alleged that Pseudoikonomou told an undercover agent, who was posing as a prospective buyer for the businesses, that he regularly underreported his gross receipts and rental income to the IRS. When meeting with the undercover agent, Pseudoikonomou allegedly said that his accountant “reports what I tell him…. You’re gonna see on my returns that not everything’s there.” During a subsequent meeting, Pseudoikonomou allegedly said, “You’re not a wearing a wire, right? You’re not a cop, right?”
The charge of aiding the filing of false tax returns provides for a sentence of up to three years in prison, up to one year of supervised release and a fine of $250,000. Sentences are imposed by a federal district court judge based upon the U.S. Sentencing Guidelines and statutes which govern the determination of a sentence in a criminal case.
United States Attorney Leah B. Foley and Thomas Demeo, Special Agent in Charge of the Internal Revenue Service’s Criminal Investigations in Boston made the announcement today. Assistant U.S. Attorney Benjamin A. Saltzman of the Securities, Financial & Cyber Fraud Unit is prosecuting the case.
