Sorry if this is a repeat question. I searched the data base and didn't see a discussion around this. I JUST found out my spouse had "single" and zero withholdings in her W4. However, I filed hers and mine together as married filing jointly. I was very surprised how much we owed in taxes this year until I found today her "single" status probably pushed us to the next tax bracket. Lovely.
I'm curious if we can amend our returns because of this misstep -- or whether we just need to eat it because the IRS has deemed her in a different status?
