Question
May I claim both the child tax credit/additional child tax credit or credit for other dependents as well as the child and dependent care credit?
Answer

Yes, you may claim the child tax credit (CTC)/additional child tax credit (ACTC) or credit for other dependents (ODC) as well as the child and dependent care credit on your return, if you qualify for those credits.

Note: If you don't have a TIN on or before the due date of your return (including extensions), you may not claim the CTC/ACTC/ODC on either your original or an amended return. However, if you apply for an ITIN on or before the due date of the return (including extensions) and the IRS issues an ITIN as a result of the application, the IRS will consider the ITIN as issued on or before the due date of your return. Also, you may not claim the CTC/ACTC on either your original or an amended return for a child who doesn't have an SSN valid for employment before the due date of your return (including extensions), even if that child later gets one. You may be eligible to claim a credit for other dependents for a child who does not have the required SSN.
