I am self employed and got a letter where they pretend I didn't send a bazillion dollars with my tax return. They are graciously setting up a payment plan for taxes I have already paid, for the low low price of $250. I must respond by the 20th if I disagree. But you can't reach anyone at the IRS because they are having technical difficulties and have been since the day I got the stupid letter.
On a separate but related note, I can't even make an estimated payment while this gets sorted out because I can't get into the website. I am afraid to mail a handwritten check because they are being stolen from the mail and altered, and deposited into online bank accounts. Still working out a fraudulent check written on my business account - 200 payment altered to just under 10K. You have to fill out a police report and the word is, this is happening all over "Chicagoland." When did day to day life become so frickin' tedious????
Would it be too much to hope they are cleaning house? Yes, but I am going to fantasize about it anyway.
Keep notes, record calls, retain all correspondence, etc.
