Automated call from this number.  The robot voice claimed to be the IRS notifying me they were filing a final notice on my open case and that I should call a different number to make a payment.  Obvious scam.

Call from this number - they posed as IRS agents. I asked  for supervisor. Both persons had Jamaican accents. They gave out confidential information (which a real IRS agent would never do). The Name (of ex husband) was connected with a phone number not a social security number. They did not care that I was not him. They Needed payment from a bank as a cash transfer to a Walmart account. NEVER WOULD THE IRS DO THIS. BE AWARE!
I am a CPA with 30 years experience with IRS.

Claimed to be IRS,I did not answer,3 calls today.Report this to the real IRS!!

Received phone call from this number saying he was IRS representative and I was going to be sued for $1500 but could meet and pay at Walmart located near my home.

These are criminal extortionists operating in overseas boiler rooms using VOIP to alter their identities and locations and out of the reach of US law enforcement.

If someone calls saying he's an IRS agent and demands that you send money immediately, hang up.

By altering their caller ID number to make it look like they're calling from an IRS office, these scammers often threaten vulnerable people like the elderly and new immigrants with things like arrest, deportation or the loss of their driver's license if they don't pay immediately for money purportedly owed.

Often leaving messages that say it's "urgent" you call them back, the scammers use common names and sometimes say they are from the IRS Criminal Division. They may even claim to know the last four digits of your Social Security number and send follow-up emails that appear to be from the IRS, TIGTA said.

They often demand that payments be made by prepaid debit card.

Once they make their threats, the scammers have been known to call back and again disguise their caller ID so it appears they are calling from the police department or the Department of Motor Vehicles (DMV).

Or sometimes when they call, they may say you have a refund due and ask you to provide personal information so you can claim it.

The real IRS will usually contact you by regular mail first, if it needs to contact you at all. And the agency never demands immediate payment by phone or asks for credit card or debit numbers if they do call. It also never asks for personal or financial information by email, text or social media.

If you get what you suspect is a scam call, report it to TIGTA through its Web site or call 800-366-4484.
