Me and my mother both did taxes. It allowed us to both be head of household since we each has two dependents. Is that wrong even though we separately took care of them?

There can only be one Head of Household in a home. Only one of you paid over half the cost of maintaining the home.

You may be able to file as head of household if you meet all the following requirements.

1. You are unmarried or considered unmarried on the last day of the year. See Marital Status , earlier, and Considered Unmarried , later.
2. You paid more than half the cost of keeping up a home for the year.
3. A qualifying person lived with you in the home for more than half the year (except for temporary absences, such as school). However, if the qualifying person is your dependent parent, he or she doesn't have to live with you. See Special rule for parent , later, under Qualifying Person.
