Can husband and wife who have never filed jointly, because they broke up, but not legally divorced and get back together, begin filing as married without being penalized?
I had always filed as HoH because I had a child before we married. When my marriage fell apart, neither one of us bothered to file for divorce. We now have two children together, but maintain separate lives and residences. For the last two years I got EIC for one child, but he claimed the child on his taxes. The other child was just born last year. We are considering becoming one household. Moving forward would there be any penalties since we were legally married? Should we file jointly or married filing separately, because I have another child that I provide for 100%?
