THIS IS A SCAM... THE IRS NEVER CALLS AND MAKES DEMANDS LIKE THIS (AND NEVER WOULD THE IRS ASK for ITUNES CARDS-as payment!!!!). A revenue officer (Collections) contacts taxpayers via letter and there is formal process to determining payment for the taxes due and owing, and all actions are only followed by written (mail). Any examination or determination of the actual monies owed, are done through examination (Revenue Agent). And criminal actions are done by Special Agent's. There is never a call threatening to put someone in jail unless they pay. If a Special Agent is going to arrest you, they will have court documentation and knock on your door. I am a former IRS Special Agent and this number is associated with people trying to rip you off. DO NOT ANSWER.
