I got one of the same two years ago. It aid I owed an additional $1100 or so. I just paid the crooks because it wasn’t worth trying to reason with criminals.

Year before last, upon getting home from wifey's cataract surgery, we were greeted with a bill from IRS for about 1700 bucks....with so much going on, I wrote a check - and a letter asking for a "plain English" explanation.

Turns out for 'other income' the IRS-trained tax preparer had used the word "Fiduciary" for the fee I charged my late parents estate as Trustee.

I wrote 'em back explaining that I'm not a professional fiduciary - one shot deal since the parents only died once. Got a clearance letter and a check back within a few weeks......but indeed it was better to pay them upfront, and then dispute it.
