He said he was from IRS and would be arrested I forwarded info to the real IRS

Any updates. I received the same phone call.

IRS Scam:

The IRS does not need to sue anyone.  They also do not bother arresting people for a few thousand dollars.  They don’t send the local police or Sheriff to arrest you.  Everything they do is done either administratively or using Federal Agents.   They don’t call you up and demand immediate payment. If you are going to be arrested, they don’t call you up to warn you.  They only issue arrest warrants for people who are really bad actors and have tried to stick them for very large amounts of money, not a few hundred or thousand.  Administratively, they send you first class letters delivered by the Post Office.  Several of them.  Ignore those, and they then send certified letters that you need to sign for.  Again delivered by the Post Office.  Ignore those and they simply freeze your bank accounts and anything else you own.  If they can do that, then why would they bother with a court case that might take them years before they get in front of a judge?  The IRS does not accept payment in Itunes Cards, Amazon gift cards, or any other type of payment other than cash, check, credit or debit card (from normal everyday citizens).
