Hi I'm in a similar situation that I just realized that I should submit Form 8833 with my 1040. However, on my 1040 I did enter in a negative number for the total amount of the tax treaty exemption being claimed on Line 21 (Other Income), with the note that U.S. {country} tax treaty, Article {article number}, and also attached Page 5 of the Form 1040NR to the back of the Form 1040 with my name, SSN, Question L filled and "Resident Alien with Tax Treaty Exemption" written down at the top. I also provided my 1042s for this tax treaty.
So anything else is corrected, but I just didn't know that I need to submit Form 8833. Should I amend my tax return in this situation that nothing really changed?
Also, I made the same mistake for more than one year. If I need to amend the tax return. Do I need to do it separately?
Thank you.
