I am unmarried but have lived with my girlfriend for the last 11 years continuously. She does not work and I pay for everything: property taxes, utilities, groceries, repairs, everything. I have her listed as a qualified dependent in the TurboTax software, but TT keeps insisting that I don't qualify as HoH, but that I HAVE to file as Single. Other filing softwares say I do qualify as HoH.
Who is correct? There is a significant difference in the return of HoH vs Single, especially since I have my withholdings for my paycheck at a maximum of Single and zero dependents.
