Hi. I am married with kids but my wife lives abroad with our other kids. Therefore, she doesn't have any SSN, while I live here in the States with one of my kids.
And so, I initially filed my tax as Married But Filing Separately. Then the next time, I was adviced to file as Head of household.
Now, this year, I'm about to file my taxes but I'm confused because the system would not progress further as it's asking for my spouse's SSN which I don't have.
It was then suggested to me to file as a Single person but I don't know if that could cause a problem for me with the IRS since I had already filed as Married but Filing Separately before.
So please, what's your suggestion?
