She is my girlfriend and we both own a house, both on the title. We filed separately and we split everything down the middle; however, she filed for the entire portion of mortgage interest and real estate taxes paid because she was unaware she had to split it since we split the mortgage. She did not file for any personal property taxes on her tax return, but does that include real estate taxes paid? Should we submit a 1040 to split the mortgage interest 50/50? Sorry, confusing scenario!
