• What is a "qualifying person" for Head of Household?

 

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.

You need to add a qualifying person in the Dependents section of TurboTax.
