Filed 3/2. First accused of identity theft (5747C letter). Went in person & verified identity. (Six hours on phone and 2+ month delay to get appointment. TWO other taxpayers there when I arrived.) I asked why we were accused. IRS rep said "Big refund.". NOT DONE YET: 2 days later, CP05A letter arrives demanding all our withholding documents. (Don't they have that data?) Web upload page does not work to do it. Faxed and uploaded documents by phone a month ago. Feel like they are just slow rolling me and looking for new excuses not to pay. Don't know, but intend never to get a refund again even if we incur penalty.
