Said if I did not call this number concerning the US Dept of Treasury, I would have to appear before a federal magistrate.  Very broken English.  Difficult to understand.

Received a call from the "said Treasury" threatening legal action but he had no name of the person he was trying to reach.  Turns out this individual was calling from India.   Be careful of this scam.

I just received this call also. At least they could get someone that speaks decent English if they want to appear to be credible.

Said if I didn't follow their orders that I may have to appear before a federal magistrate judge. Hung up on them and blocked the number.

More than likely the number they are trying to get you to call is one that charges a huge fee per minute once you connect.

Received the same call yesterday.  Same voice, obviously following a script from India.  The whole threatening tone regarding appearance before a federal "magistrate."  These calls can be very intimidating, especially to vulnerable seniors.

IRS Scam:

The IRS does not need to sue anyone.  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?  They also do not bother arresting people for a few thousand dollars for the same reasons I have already given.

If you feel you SSN has been compromised, in addition to putting a fraud alert at the 3 credit bureaus, you may want to notify the IRS.  Here is the link, fill out the proper form (probably 14039):
