Caller and supervisor both had Indian accent .. Stating they were calling from the IRS regarding unpaid taxes.. Using terms such as lawsuit warrant against you and your physical address- federal investigation- miscalculations in previous tax filings- homeland security- jail time - fines up to $30k ... Etc... clearly a scam from the get go ...  & When u call back could be prompted for a social security # .. So beware!

The caller told me that i had unpaid taxes and wanted me to hold for the supervisor. Both had clearly Indian accent. He threatened me when i said i had no unpaid taxes and should send any thing via mail.

Don't be nervous - your caller is a scammer.  If your husband did owe money to the IRS, they would mail a letter asking him to pay the balance or set up a payment plan.  More about this scam here:

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 tophishing@irs.gov.

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

There is a fairly common IRS or "tax scam" being practiced by scammers in both Canada and the USA.

He tried to scare me saying that my husband is in trouble with the IRS. When I tried to hang up, he kept threatening me that we would be in serious trouble if I did not listen to him! Left me feeling very nervous!

One thing fir sure, IRS never calls. It coressponds only through mail.

A guy called Lee Ong calls and says you owe a penalty to IRS. I asked him to provide a telephone number that he can be reached at and he gave the same number.  I asked him to provide his IRS employee ID number and he hung up the call.

This is a SCAM
