888-276-5704

Deep voiced male claiming IRS tax filing was fraudulent and demanding in threatening manner
to immediately call this (888) 276-5704 number...

Fraud on your tax filing, etc.  Beyond fraud, this is extortion.  Do not answer. Do not call them back.

Some guy called (although it appeared to rather be a recorded message) claiming to be from IRS fraud team and he calls in regards to my last year tax return. He stated that I am "hiding something from IRS". Very aggressive and threatening call.

Blocked out of hand.  I never pick up "toll free call" calls.

Said he was IRS. Said I've been cheating on my taxes. Demanded 30 grand...When I said no, he said I would be arrested within 30 minutes.

Total scam.  Originates in either India or Pakistan.   Block and ignore.   DO NOT RETURN THE CALL!

I’m an Enrolled Agent with the IRS (Inactive). IRS does not initiate contacts by phone.  US mail only.   IRS does not file lawsuits.  IRS has enough administrative authority under the IRS Code and related regulations to collect all taxes lawfully due the federal government.     Court action, if any is handled by the DOJ and all parties are entitled to legal assistance if it is a criminal matter.  But--tax disputes are for the most part civil matters.  90% of all IRS tax disputes are settled administratively.  IRS has absolutely no authority to call on local law enforcement for anything. Local law is never involved in IRS tax disputes. IRS does not threaten to involve local law enforcement or to arrest you for nonpayment of federal taxes.  IRS has no powers of arrest as related to ordinary tax disputes.  Having a deficiency in taxes owed by way of audit is NOT a crime.  IRS does not cold call anyone and demand immediate payment of  money.  IRS does not ask for financial information over the phone.   IRS does not accept Green card money paks or Itunes cards or similar for payment in any case.  No one is prosecuted for ordinary tax disputes. IRS has absolutely no authority over anyone's professional license. Professional licensing is handled by state governments.  Yes, levies on property to satisfy an existing tax obligation do occur, but only after a very long period of negotiation. And yes, liens are placed on individuals but  usually after a lot of negotiation and a failure to reach a settlement.   All determinations of tax liability are subject to appeals.  All  contacts by the IRS are initiated by US mail.

Everyone please note:

Effective in April of 2017, the IRS will start using private debt collectors who may, in fact contact you. Note the IRS will notify you by mail that your account is being turned over to a private group.  The private collector will then send you another letter.  They may call you after that point.

I told them to come and arrest me. Then I could have free housing, medical, and 3 meals a day. I could save some money. He hung up.

On July 21, 2017, my phone answering machine recorded  male voice saying "Extremely time sensitive and urgent ..... claiming IRS tax filing was fraudulent, I would be legally sued and demanding in threatening manner
to immediately call this (888) 276-5704 number."
  1) The first tip-off that this is a fraudulent call, is that it is so very urgent and I must respond right away!!!
   2) The second tip-off that this is a fraudulent call, is that the IRS and government agencies, send paper letters, and do NOt phone call. This is a well known fact, and besides phone calls are too time consuming & expensive for them!
  3) The third tip-off that this is a fraudulent call, is that when I called back, I could hear a VERY busy call center in the background, and the guy asks my name: Since he has my phone number on his computer,  I tell him he can tell me. my name:  Which he correctly does, with heavy foreign accent, I say "Yes you are correct, go ahead with what you want.
  4) But I apparently was acting too suspicious, and he immediately hanged up, terminating the call.
