By the way, the Philadelphia office of the IRS is one of the main ones for sending out these kind of notices. I live in Texas and there is a huge facility for the IRS in Austin but this went to Philadelphia. When my mom and dad were still alive(and filing in Atlanta) and I was overseeing their finances they got the same kind of bullshit letter from the same office saying that they owed like, $60,000 because somewhere at the IRS they lost half of the return. In the end we owed them something like $26.00 due to improperly figuring some profit on a stock sale. Same accountant handled that one!
