IRS Letter 4883C:
The questions they asked me had nothing to do with the prior year return, such as which financial institution did you get your mortgage? Your monthly mortgage payment amount? Which company did you get your gas card in Feb 2007? I couldn't answer the last question, so the computer could not verify me. I was asked to fax them my phone number, so someone from IRS can call me. Does anyone have the same experience? Shall I call IRS again to get another set of questions?
