It was a pre-recorded message stating that they were the IRS and that I needed to call back immediately.  Of course, it wasn''t.  I called back from a different number.  When they finally answered, the man who answered was barely understandable.  He wanted my phone number.  I told him that he should have it.  He insisted.  I then told him that I knew that he was scamming people out of thousands of dollars.  He then began to use every four letter word in the book.  I just hung up.

The IRS reminds people that they can know pretty easily when a supposed IRS caller is a fake. Here are five things the scammers often do but the IRS will not do. Any one of these five things is a tell-tale sign of a scam. The IRS will never:
Call to demand immediate payment, nor will we call about taxes owed without first having mailed you a bill..

Demand that you pay taxes without giving you the opportunity to question or appeal the amount they say you owe.

Require you to use a specific payment method for your taxes, such as a prepaid debit card.

Ask for credit or debit card numbers over the phone.

Threaten to bring in local police or other law-enforcement groups to have you arrested for not paying.

Got the same call...its appears on your phone with  no specific city just says United States . Scam scam scam claiming to be IRS. Block them and forget.
