This sounds like a burgeoning new scam in which they threaten jail and so forth if you don't make immediate payment. First, the IRS always contacts by mail and rarely calls, and when they do, they never make threats.
Being told I needed to sign up with OBAMA CARE INS. NOW, or I'll be taxed when I file my taxes this year! He said it shows I don't have INS. & gave me a number to go by when calling back to sign up for OBAMA CARE!! Thank God, I have BCBS & I don't have to have OBAMA CARE INS.
This number calls to fish for people to swicth credit card debt. They call AGAINST the National Do Not Call registry, and agaiinst the Indiana Do Not Call Registry.
