I was recommended an EA to help me file my taxes and he asked me to file an extension as he needs more time to read about my specific tax situation.
If I were to file an extension could I, later this year, choose to file either jointly (MFJ) with or separately (MFS) from my wife?
I read something about couples not having the ability to choose to file jointly after the April 17th deadline (after which they could only choose to file separately), but it might have to do specifically with amending a tax return rather than extending it
My tax situation (if that could change the answer) is detailed here: F1 student, as a non-resident, filing married separate tax return with US Citizen wife
