Firstly, amazing post!! Thank you for taking the time to share your experience!
I wanted to ask you about the most recent year's tax return. I too have not filed U.S. taxes for years 2021-2025 since I have been living abroad and haven't had any income in the U.S. So, my question is as follows: Should I bother to quickly file for 2025 to meet this requirement or should I go about your route of writing an affidavit letter?
Was your situation similar to mine (I wonder if my reason for not filing is acceptable)? For the affidavit letter, did you use an official form or template? Did you have to get it notarized?
Thanks again for your help and thanks in advance for your continued help!
