TX- wife moved out in may05. She is now living with her boyfriend. I have started using TurboTax. It says that according to the 05 tax law that though she and I are not legally divorced that since she has not lived with me after 07/01/05, we are considered "unmarried" and we can file as HoH. She has her son and I am claimng our 3 girls, this will allow me to get back $1000 and her $3000 as she only made about 15K. Just making sure this is correct. I walked through all the step to verify that we could each file as HoH on our taxes. Any tax help?
