Called on 5/5/15 and claimed to be with legal department of IRS.

I got a call from this number also.  703-9578-7675
The man first just said he was with the IRS and there was a law suit being filed against me.
He didn't give his name until I asked for it (Richard Parker) ... he sounded like he was from India.
I told him that I know about this scam going around, and he got defensive.  I asked for a number to call back and he actually gave me the IRS 800-829-1040 number.
I called back the 703 number, and asked for him by name, and another foreigner answered sounding annoyed that I was asking for Richard Parker and that I had this number.  He asked for the badge number, to which Parker didn't supply me with.  I told this POS that I had reported this number to the scam department of the IRS, and that I gave this information to my FBI friend.  He asked if I was recording this call, then hung up.

Just received a nasty message on my answering machine from IRS, I called back and they asked me if I was Donna and did I have criminal lawyer. I needed one because Of income tax evasion. I told him I file every year, he said someone came to my home on Sept. 2014 and I told him I was here all day my calendar showed no appointments, and no one came here with 35 pages for me to sign. He said his name was Jason and gave me a fake badge number. I told him I thought the call was a fraud and hung up. I hope you find these people. They were foreign and sounded quite forceful. The message was from a woman.

There is a widespread IRS (or CRA) or "tax scam" being  practiced by scammers on both USA and Canadian residents.

Short answer:
The IRS never initiates a contact via phone.
They always send a snailmail first.

Had a message on my answering machine that it was the IRS and that I needed a criminal attorney for Fraud and not filing.  I know this is a scam since I file every year with my accountant.  They need to stop these people because I'm sure they scare a lot of innocent people.
