I got a letter from the IRS the other day saying I owed a huge amount on 2022 taxes. After looking everything over, I think what happened was I printed out a 2023 estimated tax form instead of 2022 form and sent in a huge check. I have a copy of the canceled check with a US Treasury stamp on it. On the check I wrote 2022 est tax, but that probably wouldn't override the voucher form.
I'm trying to create a login with IRS to see my data and check if that is the explanation. I've spent an hour and a half going through their id.me contractor's hoops, and fell off the fast track somehow. Maybe because my documents have a mix of middle name or middle initial? Maybe because my internet provider looks like I'm in a different state?
So now I'm waiting for an email telling me they have looked at the pictures of additional documents and they are ready for a video call to interview me. What a process.
If I get past that, I may be able to verify my situation with IRS.
I don't know why IRS wouldn't take any money you send them and apply it to your debt, but that's red tape for you. I hope there is a chance to talk them into that and avoid the penalties.
