I missed the phone call and got a message saying that I got into this tax fraud. I need call them before get a lawsuit. I suspected it was a scam. I called back and immediately answered by a  person with foreign accent,  "US department of treasure".  He asked for my name, I told him that you don't even know my name why do you call me.

Gave a completely fake name and they still went on and told me that I owed money due to accounting discrepancies on my 2012 and 2013 taxes. I let him go on for a while and told him he was wrong and when he said they would send someone over to arrest me, I asked what address he had and he said he couldn't share that information - then when I called him out and told him I knew it was a scam, he asked if I would like to be f**cked and what color bra I was wearing. nice.

rcvd call could hardly speak English. threatened me with putting a bomb in my car and did not even know what kind of car I have, Big telemarketing room with a lot of noise.
Said his name was Osama hakea Told him I was a cop and to stop calling. He hung up

Got a call from this number saying I had tax fraud but it was a recording and that if I didn't call them back my account would be garnish and wage and that I could go to jail.  I called back the number and it wasn't a working number

Keep getting calls from this number saying that this is a  IRS final notice concerning tax fraud against me. This is a scam and if you call and tell them and threaten to call authorities they hand up. Sounds like you are calling India not the US very thick accents.
