No, not receiving advance Child Tax Credit payments does not mean you are ineligible for the Child Tax Credit.
The advance payments are simply an early disbursement of a portion of the Child Tax Credit that you may claim on your tax return. If you did not receive these advance payments, you can still claim the full amount of the Child Tax Credit when you file your tax return. This applies even if your main home was outside the United States for more than half the year, or if you became eligible in 2021 due to the birth or adoption of a qualifying child. Additionally, if you did not receive advance payments because your income was too high based on prior tax returns, or due to other reasons such as not having an ITIN or your child not having a valid SSN, you can still claim the full credit amount on your tax return if you meet the eligibility criteria.
