head of household
n. 1) in federal income tax law, the person filing a tax return who manages the household which has dependents such as children and/or other dependent relatives living in the home, but does not file on a joint return with a spouse. The calculation of taxes is somewhat more favorable to a head of household than to a person filing singly. 2) anyone who manages the affairs of the family living in a household, who need not be the husband/father or wife/mother, but could be a grandparent, uncle, aunt, son or daughter. 3) "head of family."
