I have received three calls from someone who claims to be Alex Ferguson. He says he is with the US Treasury and I need to contact him regarding enforcement actions that are being ignored.

I too have gotten this call and I simply ignore it. The IRS won't contact you this way!

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.   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.    If LE is necessary, US Marshals do the job.  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 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.

We got a few calls from someone with a very strong accent, probably Hindu or Pakistani, claiming to be representing the US National Treasury, and to contact them regarding Judicial orders!

Kept calling my number and left message in a theaten voice.  Voice mail claimed to be from US treasury, and the Indian accent voice said that if I don't call back, a judge will issue a warrant arrest.

I hope that the law enforcement will catch these crook scammers.
