I need to change from single to head of household. I also paid child support all year. What do i do?

[Coleen3 · Accepted solution]

To qualify for Head of Household, you child has to live with you over half the year. Normally, the spouse that pays child support is not the custodial parent.

Head of Household

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.

Qualifying Person

See Table 4 to see who is a qualifying person. Any person not described in Table 4 isn't a qualifying person

[Opus 17]

Child support is not tax deductible.  It doesn't get listed on your tax return.

Unless your state allows a deduction on the state return.
