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.
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.
