This sounds logic, however, when you want to file "Married filing separately", you need to indicate your wife's name as well as her social security number, and provided your wife does not have a social security number, then you need and TIN number for her. what you do if the taxpayer who was married last day of the year is now divorced and his ex wife is not welling to work with him? (this is a real case that i enountered)Thanks!
