No, an individual may be a dependent of only one taxpayer for a tax year. You can claim a child as a dependent if he or she is your qualifying child. Generally, the child is the qualifying child of the custodial parent. The custodial parent is the parent with whom the child lived for the longer period of time during the year.

However, the child will be treated as the qualifying child of the noncustodial parent if the special rule for children of divorced or separated parents (or parents who live apart) applies. See Publication 504, Divorced or Separated Individuals for more information. This rule requires in part, that both of the following conditions are met:

• The custodial parent signs a Form 8332, Release/Revocation of Release of Claim to Exemption for Child by Custodial Parent or a substantially similar statement, and
• The noncustodial parent attaches the Form 8332 or a similar statement to his or her return.

If the custodial parent releases a claim to exemption for a child, the noncustodial parent may claim the child as a dependent and as a qualifying child for the child tax credit or credit for other dependents. However, the noncustodial parent may not claim the child for the purpose of claiming head of household filing status, the earned income credit, the credit for child and dependent care expenses, or the exclusion for dependent care benefits.
