A Quincy, Massachusetts, man who concealed more than $10 million in corporate revenue to evade taxes has been sentenced to 18 months in federal prison. Su Nguyen, the owner of General Employment Services (GES), will also serve 12 months of supervised release and pay more than $2 million in restitution.
The sentencing, announced December 2024, follows Nguyen’s guilty plea in May 2024 to three counts of aiding and assisting in the filing of false tax returns. His case first came to light after an October 2023 federal grand jury indictment, which detailed years of deliberate tax fraud.
Between 2016 and 2020, Nguyen operated GES, a temporary employment agency serving Massachusetts. His clients paid for services primarily by check, but instead of depositing all the payments into GES’s business account, Nguyen cashed the majority of them—over $10 million—at a check-cashing business in Worcester. While a portion of the revenue was reported to the IRS, the cash transactions were hidden. Nguyen used the unreported funds for personal expenses and paid employee wages off the books, sidestepping his tax obligations.
The scheme enabled Nguyen and GES to avoid paying more than $2 million in taxes. This deception, however, did not go unnoticed.
IRS Criminal Investigation (IRS-CI) investigators pieced together the evidence, tracing unreported transactions and exposing Nguyen’s attempts to cheat the system. Their efforts underscore the agency’s commitment to ensuring everyone pays their fair share.
Nguyen’s sentence sends a strong message that tax fraud won’t be tolerated. IRS-CI remains dedicated to protecting the integrity of the nation’s tax system and pursuing those who exploit it for personal gain.
Each month, IRS-CI leadership selects one criminal case adjudicated during the previous month to serve as the Tax Case of the Month. This month’s case was investigated by IRS-CI’s Boston Field Office.
