A Keswick man was sentenced to 18 months in federal prison last week for failing to pay over $700,000 in employment taxes for his business, and for making a false statement for purposes of obtaining a Paycheck Protection Program (PPP) loan for the business.

According to court documents, 60-year-old Thomas Sieren was a co-owner of TCS Fabricating, Inc. during the years 2014 through 2020. In that time, Sieren failed to pay $703,615.69 in employment taxes to the IRS. This included failure to pay taxes that he had collected from TCS employees through withholding, as well as matching contributions to Social Security and Medicare. In 2020 and 2021, Sieren obtained two PPP loans on behalf of the company in the total amount of $237,379. The loan applications misrepresented that TCS had paid its payroll tax obligations.

As part of his sentence, Sieren will be required to pay TCS’s unpaid payroll tax obligations, together with interest and penalties. He will also be required to pay restitution of $237,379 to the US Small Business Administration. Following his release from prison, Sieren will be required to serve two years of supervised release.

The case was investigated by the Internal Revenue Service-Criminal Investigation.
