A friend of mine was audited in mid Feb. since then i have basically paid his living expenses. ive seen documents and he's signed promissory notes and given me ultimated power of attorney which im still waiting on the irs to process. he has shown me documents(all documents look like something off microsoft word) that have 3 or more different dates on when his case was solved. and most recently he told me that they were sending a check on december 20th. how long can an audit last and Ultimately is the guy full of shit?
