Yes, you can still receive the Child Tax Credit if you did not receive advance payments during 2021. You can claim the full amount of the Child Tax Credit when you file your 2021 federal income tax return. This applies even if you do not normally file a federal tax return. Additionally, you may be eligible to claim other credits on your 2021 federal income tax return, such as the Earned Income Tax Credit, the Child and Dependent Care Credit, and the 2021 Recovery Rebate Credit if you did not receive the total amount of third-round Economic Impact Payments for which you were eligible.
