Q. I'm really confused because I have coworkers that have similar situations, example: he has his partner ( not married) who is on disability and he claims her as a dependent and claims head of household without any issues?
A. Your coworker is erroneously claiming HoH filing status. if you use a tax preparer or good software, like TurboTax (TT), they will ask the right questions to keep that from happening. In particular, TT asks you, in the personal info section to identify the relationship of your dependent. In your case, you check "other". TT will not let you claim HoH.
