For some reason a lot of these scam IRS calls originate or use 415 area code.

Ignore 'em.  Total scam.

got a wild call from this guy saying I needed to call this attorney RIGHT NOW
He said I have a law suit against my name.  It was urgent.
The number he gave me to call was the same number he called on.

I received a call from 415-251-3754 at 1:30 on 2/15. The caller is Asian and difficult to understand. He claimed he was with the IRS and I needed to contact him to avoid legal ramification and consequences.  Claimed that I owed the IRS back taxes and fines.

There was a lot of background noise, as if he was in a call center.

Did not return call.  

I must call this number immediately or face action,

I call the number and a recording says to leave a  message but the VMbox is full.

Can't someone stop them?

GOT A CALL FROM A CHRIS BROWN SAYING HE WAS FROM IRS... WE JUST FILED OUR TAXES... THEY DO NOTIFY YOU BY MAIL BEFORE CALLING. THIS PERSON COULD NOT EVEN SPEAK ENGLISH VERY WELL..
WHAT IS GOING ON WITH THIS? AS SOMEONE STATED ABOVE THEY ALSO GIVE A AGENT REPRESENTATIVE NUMBER .

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.

this man called and state error on my taxes and an attorney will be calling for legal action.  he states he is from irs.
can barely understand him.

These guys have sweat shops set up in India and elsewhere that do VoIP call forwarding so it looks like they are from the US but they are not. They have auto dialers to do DoS (Denial of Service) on companies and light up the entire switchboard. They are extortionists that are scaring people into sending money. We called the around, even the FBI, and nothing can be done. If you call the carrier from where this number originates, they will shut the number down but that is only an irritant for them and doesn't solve anything. All you can do is don't talk to them and they will get bored and move along.

Scam phone call claiming I must return the phone call immediately regarding an IRS deficiency. I immediately called the IRS and they said it was a scam. I am also reporting this to the attorney general.  

call from Sonja, thick accent, said she was from IRS and that I must call back.  Called back and "Officer Webster's" vmail box was full and could not receive a message.

I got a call from a Kevin Scott claiming that he was from the IRS and that I owed them money and I should have received a letter from them.  He then proceeded to want my personal information 'verified' to which I told him he could go to heck and if the IRS needs something from me they need to send me something in writing otherwise I would not confirm anything with him.  Got his IRS ID# (which all agents should have and identify themselves with when they call you, this guy did not know I worked for a lawyer and know this stuff).  Anyways, ended up on have IRS send me a letter and I will respond to them in person.

Got a call from this number 415-251-3754. Knew it was a scam. since when do you have a direct line to an agent. Said he was Officer Kenneth Metzger. Since when does the IRS call you. I have never received a call from the IRS. Only letters.

I have gotten this same call. This is the second incident. When I told them I knew this is a scam they hung up on me. My police Dept. didnt return my call when I left a message to file a complaint. What a scam!

I got a call today from IRS that left message on my phone , said to urgently call back (415)251-3754, when I called back the VM said Officer Kenneth Webster, mailbox was full. I was panicked but don't owe money so it didn't make sense.

Caller said he was with IRS could barley understand what he was saying.
He said I had a tax debt when I said I don't think so he hung up...

Got a call from this number. The caller did not leave any message.

just received a call on my daughters cell phone claiming they are from the IRS and that I must return their phone call immediately or face legal action.   It was an Indian guy and i counld not understand what the hell he was talking about. i blocked my number and called it back and you cannot leave a message,   I couldnt undetstand the b*****d, but let him call me back again and I will let him have it big time.  I have filed this  number with the IRS and I also sent this information to a few US Congressman.  come at us you foreigners...UNITED STATES rules

2 calls so far today. Messages are not understandable, except regarding police coming soon. I'm still waiting.

Got a call form the same number and wanted me to pay money I did not owe- told me I was going to be arrested - so I advised them to come and get me- hung up on me several times

please be aware that this is a scam!!!!!!!!!!!!!

I got the same call from this "so called" IRS agent.  I looked his number up and found all the above information.  He called again and I could harldly understand this JERK.  I told him not to call again and hung up.  He called again.  I screemed at him to stop calling my number, he called again.  I told him I was reporting him and hung up again.  He called again, so I screamed really loud......F### YOU!!!  He did not call back.  I am sick and tired of these foreign scam idiots!!!!!

Got a call from number 415-251-3754 , says being sued by IRS , owe money . must call back or have my attorney call them.  BIG SCAM!!!!!!!

I just received a call from this number, answered, said hello and of course no one answered. Just an F.Y.I. People in other countries are dialing these numbers through a computer. They have software that can pick a random number in the U.S. that is not being used to dial to you. As previous bloggers have said, do NOT call the number back. Do not give ANYONE your information over the phone.
[As a footnote, this is along a similar line as the one ring phone scam to mainly cell numbers to try to get you to call it back. This scam has a "pay per minute" attached to it and you will pay through the nose if you even so much as call the number.]

got a call at 9am est claiming he was IRS.  I called the FBI to report but they didn't answer the phone.

My wife received a call from this number today and gave me the phone because they gave her my name stating that they were with the IRS.  I have caller ID but still asked the person calling for a call back number.  He provided me with (415) 251-3754 and requested I contact the agent in charge Kenny Webster asap regarding a law suit against me.  Idiot didn't realize that I am a detective.  The number comes back to a landline with a service provider of YMAX Corp possible Magicjack voip in Novato or Igancio CA.  Don't fall victim to this scam and contact your local police dept and/or the IRS.    

I got a call from a guy with very broken English, he said to call back a number regarding my irs debt.  I called the guy he told me to and he said that the programs have changed (I'm on a payment plan) and that if I didn't send $2000 an officer would come out to my house or office and arrest me.  I panicked and am so glad I googled the number.  

He says he is from the IRS and for me not to ignor his call.  I answered the phone, but he did not say anything.  Then he left me a message stating I needed to call him back because I have an IRS debt.  I called the number back and you cannot leave a message because the mail box is full.  I believe this to be a scam.

I received a call from Sonya on my answering machine. She had a heavy foreign accent and it was hard to understand most of the words other than 'IRS', 'avoid legal action', 'call immediately'. I called the number and Michelle Brown answered Internal Revenue Investigations and said she was the lead investigator. She asked if I was aware of my back tax issues. When I said I do not have any issues with the IRS she hung up on me. There you have it... total scam!
