A New York man has pleaded guilty to a federal tax offense.  58-year old James Guerra worked as an accountant for the owner of several restaurants in Connecticut and New York, including Pinocchio Pizza locations in Wilton and Pound Ridge.  The U-S Attorney's office alleges that Guerra knew that Bruno DeFabio had a practice of paying his employees in cash and that the owner was failing to collect required withholding taxes from his employees.  The revenue was not deposited into the restaurants' operating bank accounts, and taxes were not payed to the IRS.  Guerra reviewed and approved DiFabio’s quarterly tax returns.  He pleaded guilty to one count of willful failure to collect and pay over withholding taxes, and offense that carries a maximum of five years in prison.  A sentencing date is not scheduled.  Guerra is released pending sentencing.
