Why am I unable to change my filing status to head of household since I qualify?

Are you sure you qualify to file as HOH?    

Am I 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.

Did you enter someone that qualifies as your dependent?  Did you answer the question concerning providing over one-half the cost for maintaining a home?  Did you select a filing status of either Single or Married Filing Separately?  If filing separately did you indicate that you have not lived with your spouse at any time during the last six months of the year?  Did you indicate that no one else in the household supports the dependent?

Go back and review your answers in the My Info section of the program.
