Defendant avoided paying approximately $3 million in taxes to IRS

BOSTON – The former owner of JMS Contracting, a general contracting business based in South Boston and Quincy, was sentenced yesterday in federal court in Boston for concealing business income from the Internal Revenue Service (IRS).

John Michael Sacco, 54, formerly of Quincy, was sentenced by U.S. Senior District Court Judge Patti B. Saris to six months of home confinement and three years of supervised release. Sacco was also ordered to pay restitution to the IRS in the amount of $3,059,887.

Sacco managed construction projects under the name JMS Contracting. From 2014 through 2021, Sacco received over $9 million from JMS’s customers. Rather than depositing JMS’s gross receipts into business bank accounts, Sacco cashed most checks from customers, used proceeds to purchase supplies and pay subcontractors in cash and retained remaining cash to pay personal expenses. Sacco failed to issue required tax forms to subcontractors and failed to file required forms with the IRS with respect to amounts that JMS paid to its subcontractors. By not reporting JMS’s actual receipts on tax returns that he filed for certain years and by filing no tax returns in other years, Sacco underreported his personal income tax obligations, causing a loss to the IRS of over $3 million.

United States Attorney Leah B. Foley and Thomas Demeo, Special Agent in Charge of the Internal Revenue Service Criminal Investigation, Boston Field Office made the announcement. Assistant U.S. Attorney David M. Holcomb of the Criminal Division prosecuted the case.
