Rang twice but hung up before answer machine picked up.  Caller ID stated "IRS 1-978-699-3050". Strongly suspect a scam.

This person (978-699-3050) called my employer on a Saturday stating they where the IRS and needed to talk to me. This is a scam. First of all the IRS does not call you. They do everything by mail. And What IRS agent works on a Saturday. This such a scam.

They called twice after 9:00 P.M.  No message nor voicemail.  When I called back, the response on the other end is a disconnected number so someone is calling me with a fraudulent caller identification.  Last time this happened:  It was an IRS scam with Indian speakers, constantly putting me on hold etc threateningly with legal action etc.  I told them to cease and desist with their fraud or I would pursue legal action for harassment and fraud.

asked me to fax (1-855-253-6835)  the first copy of my 8379 tax form to a lady name Ms Gauthier I
D# 1904194.  She said the top first form was missing.

For heaven's sake, DON'T DO IT.  The IRS will send you a written request via USPS if they need any more information about your tax return or if there is a problem.  The IRS is warning people about telephone scams to get your information.  Call the IRS directly if you are unsure.  Here is the IRS post concerning scams.
