Get your taxes done using TurboTax

"Considered not married" is a limited tax term. It only means that you may use HoH as  a filing status if you meet the other requirements (and you apparently do). But, you are still allowed to file as Married Filing Jointly (MFJ), if the two of you can agree to o so, even though you haven't lived together for a long time.
