If your son had check signing authority and did, in fact, sign some company checks, the IRS could argue that he was a "responsible official" and propose to assess the trust fund recovery penalty against him for part of the unpaid payroll taxes. (IRC 6672). However, you have a right to appeal IRS' proposed assessment against your son, and even take the case to the US District Court. However, you should retain a knowledgeable tax attorney to help you through the process.
