DO NOT CALL BACK. As a guy who just went through a big ordeal with the IRS, I know that they don’t operate that way. As an aside, the IRS lackeys I dealt with were always very nice and professional. Except for the corrupt leadership, I give the organization high marks.
I had a call from “Microsoft’s Virus Detection Team” that they had received an error code from my computer that it had a virus. I told the scammers to go away.
I just had to call the IRS on some unpaid 941 taxes and agree - the gal was very friendly and helpful. I told her that I would take care of things and already had one form filled out and the check written. And then said “Just so I can put something in the computer to say we talked, do you think you can get the other ones filled out and paid within 30 days?”
From the tone of the letters “...late payments may be deemed a criminal offense subject to fines or imprisonment” it was a surprise.
LOL. That’s like saying that, except for the leadership, Nazi guards were always polite and professional in sending Jews to the gas chambers.
