Tests to Meet
In general, all four of the following tests must be met to claim someone as a qualifying child.

Relationship Test
The child must be your child (including an adopted child, stepchild, or eligible foster child), brother, sister, stepbrother, stepsister, or a descendent of one of these relatives.
An adopted child includes a child lawfully placed with you for legal adoption even if the adoption is not final.
An eligible foster child is any child who is placed with you by an authorized placement agency or by judgments, decree, or other order of any court of competent jurisdiction.

Residency Test
A child must live with you for more than half of the year. Temporary absences for special circumstances, such as for school, vacation, medical care, military service, or detention in a juvenile facility count as time lived at home. A child who was born or died during the year is considered to have lived with you for the entire year if your home was the child's home for the entire time he or she was alive during the year. Also, exceptions apply, in certain cases, for children of divorced or separated parents and parents of kidnapped children.

Age Test
A child must be under a certain age (depending on the tax benefit) to be your qualifying child.

Dependency exemption, head of household filing status, and EIC
For purposes of these tax benefits, a child must be under the age of 19 at the end of the year, or under age 24 at the end of 2005 if a student, or any age if permanently and totally disabled.
A student is any child who, during any 5 months of the year:
1. Was enrolled as a full-time student at a school, or
2. Took a full-time, on-farm training course given by a school or a state, county, or local government agency.
A school includes a technical, trade, or mechanical school. It does not include an on-the-job training course, correspondence school, or night school.

Child tax credit
For purposes of the child tax credit, a child must be under the age of 17.

Credit for child and dependent care expenses
For purposes of the credit for child and dependent care expenses, a child must be under the age of 13 or any age if permanently and totally disabled.

Support Test
A child cannot have provided over half of his or her own support during the year.

Exception
For purposes of the EIC only, the Support test does not apply.

Qualifying Child of More Than One Person
Sometimes a child meets the tests to be a qualifying child of more than one person. However, only one person can treat that child as a qualifying child. If you and someone else (other than your spouse if filing jointly) have the same qualifying child, you and the other person(s) can decide who will claim the child. If you cannot agree on who will claim the child and more than one person files a return using the same child, the IRS may disallow one or more of the claims using the tie-breaker rule explained in Table 1, next.

When More Than One Person Files a Return Claiming the Same Qualifying Child (Tie-Breaker Rule)

IF . . . THEN the child will be treated as the qualifying child of the. . .
only one of the persons is the child's parent, parent.
both persons are the child's parent, parent with whom the child lived for the longer period of time. If the child lived with each parent for the same amount of time, then the child will be treated as the qualifying child of the parent with the highest adjusted gross income (AGI).
none of the persons are the child's parent, person with the highest adjusted gross income.
