You will not be able to file a tax return as "Head of Household" if you do not have a qualifying dependent.

If you qualify as Head of Household, when you enter your marital status (single or married filing separately) into MyInfo, and then enter your qualifying dependent, TurboTax will offer HOH as your filing status.
