At 3:36 p.m. on August 20,2104, I received a call from a Julie Smith (sounded like a recording) telling me to return the call or have my lawyer return the call before legal action is taken against me by way of the IRS. I knew this was a scam because the IRS contacts you by mail, so I googled the phone number and found others have received the same or similar phone call.  

Scammer pretending to be calling from the IRS.  Recorded message.

I got a call and left message from this number asking me to call back to avoid legal actions from IRS. This  call is very very suspicious.  Do not give out your ID.

Received the same call today like others from 4152519813 in Boston, MA.

The caller left message twice with same "legal allegation" from the IRS. I am a CPA and I know IRS does not contact taxpayer by phone. I have a client who was contacted by the same caller recently.
