A Massachusetts staffing firm owner was sentenced to prison and ordered to pay more than $2.5 million in restitution through a tax fraud scheme, the US Department of Justice reported.

Det Tran, 62, of Dorchester, Massachusetts, will have to spend one year and one day in prison followed by three years of supervised release, according to the department.

Tran owned and operated HTP Temp, a temporary staffing firm, from 2018 through 2021. The department said Tran paid $8 million in “off the books” cash wages to HTP employees. As a result, he evaded paying more than $2.1 million in employment taxes to the IRS.

He had previously pleaded guilty in September 2024 to two counts of failure to collect and pay over employment taxes, according to the department.

An attorney for Tran has been contacted for comment.
