So if I understand you correctly, it's not required to amend?
I'm not interested in getting more money, I know that filing single with zero deduction gets you less.
I just wanted to know if it's required by law to do the changes. (amend) from single to married.
And in case doing the amend, I can just amend married filing separately, since my wife is already never visited the states. So in this case I guess I would just need to submit the 1040 for the last 4 years for federal, amending single to married filing separately and that's it ?
