I just received a call too.  A guy with a Nigerian accent acting to be an IRS agent, threatening to put me in jail if I don't pay $2k+.  I am reporting it to 800-366-4484 ASAP.

I just received the same exact phone call! Spoke with local police department, don't fall for it! I got the same exact scenario

I got a message on my home phone saying that they are from IRS and that I have to call back this number. I called today 1/4/2014, spoke to someone called Matthew Jenkins. He claimed that I am a subject in 3 crimes and that I didn't file form 51 for year 2010. He said that if I didn't take action within 24 hours, legal action will be taken against me. I told him I will talk to my accountant about it just to get off the phone. Please DON'T fall for that.

Some one by Name of Mathew Jenkins Ph number 646-757-1262 is calling and acting on behalf of Federal Crime Branch. 32 West Bank Building, New York, NY. 11085, Called me today 3rd Jan 2014, at 3;30 PM.
They are threatening that we owe Fed Tax 2020/- I forgot to file my Form 61 in 2010. And if we do not pay right away the Police will be in your home within 24hrs.. with as arrest warrant. I have to pay them by my debit card purchased from Wal-Mart.
They are very smart and sounded very real and threatening. I also verified that they were lying when I found out the Form 61 is agriculture form nothing to do with me.
I never made any income in Farm.
I pressed my mute button and called IRS right away to verify. While I was doing my research I heard them talking in HINDI in the back ground , then I realized that this is a big SCAM, these are wastage DNAs of the society that are targeting innocent people. Gave my Wife almost an heart attack. She almost fell for it and was ready to go to Wal-Mart to get the card.

Please do not fall for this. Report this to Attach is the letter from the IRS. If you get a phone call from someone claiming to be from the IRS, here?s what you should do:
?If you know you owe taxes or you think you might owe taxes, call the IRS at 1.800.829.1040. The IRS employees at that line can help you with a payment issue ? if there really is such an issue.
?If you know you don?t owe taxes or have no reason to think that you owe any taxes (for example, you?ve never received a bill or the caller made some bogus threats as described above), then call and report the incident to the Treasury Inspector General for Tax Administration at 1.800.366.4484.

WASHINGTON ? The Internal Revenue Service today warned consumers about a sophisticated phone scam targeting taxpayers, including recent immigrants, throughout the country.

Victims are told they owe money to the IRS and it must be paid promptly through a pre-loaded debit card or wire transfer. If the victim refuses to cooperate, they are then threatened with arrest, deportation or suspension of a business or driver?s license. In many cases, the caller becomes hostile and insulting.

?This scam has hit taxpayers in nearly every state in the country.  We want to educate taxpayers so they can help protect themselves.  Rest assured, we do not and will not ask for credit card numbers over the phone, nor request a pre-paid debit card or wire transfer,? says IRS Acting Commissioner Danny Werfel. ?If someone unexpectedly calls claiming to be from the IRS and threatens police arrest, deportation or license revocation if you don?t pay immediately, that is a sign that it really isn?t the IRS calling.? Werfel noted that the first IRS contact with taxpayers on a tax issue is likely to occur via mail
Other characteristics of this scam include:
Scammers use fake names and IRS badge numbers. They generally use common names and surnames to identify themselves.
Scammers may be able to recite the last four digits of a victim?s Social Security Number.
Scammers spoof the IRS toll-free number on caller ID to make it appear that it?s the IRS calling.
Scammers sometimes send bogus IRS emails to some victims to support their bogus calls.
Victims hear background noise of other calls being conducted to mimic a call site.
After threatening victims with jail time or driver?s license revocation, scammers hang up and others soon call back pretending to be from the local police or DMV, and the caller ID supports their claim.
If you get a phone call from someone claiming to be from the IRS, here?s what you should do:
If you know you owe taxes or you think you might owe taxes, call the IRS at 1.800.829.1040. The IRS employees at that line can help you with a payment issue ? if there really is such an issue.
If you know you don?t owe taxes or have no reason to think that you owe any taxes (for example, you?ve never received a bill or the caller made some bogus threats as described above), then call and report the incident to the Treasury Inspector General for Tax Administration at 1.800.366.4484.
If you?ve been targeted by this scam, you should also contact the Federal Trade Commission and use their ?FTC Complaint Assistant? at FTC.gov.  Please add "IRS Telephone Scam" to the comments of your complaint.
Taxpayers should be aware that there are other unrelated scams (such as a lottery sweepstakes) and solicitations (such as debt relief) that fraudulently claim to be from the IRS.
The IRS encourages taxpayers to be vigilant against phone and email scams that use the IRS as a lure. The IRS does not initiate contact with taxpayers by email to request personal or financial information.  This includes any type of electronic communication, such as text messages and social media channels. The IRS also does not ask for PINs, passwords or similar confidential access information for credit card, bank or other financial accounts. Recipients should not open any attachments or click on any links contained in the message. Instead, forward the e-mail to phishing@irs.gov.

More information on how to report phishing scams involving the IRS is available on the genuine IRS website, IRS.gov.
