2021 Child Tax Credit and Advance Child Tax Credit Payments — Topic F: Updating Your Child Tax Credit Information During 2021

A1. The IRS launched on IRS.gov a Child Tax Credit Update Portal (CTC UP), which  will allow you  to elect not to receive advance Child Tax Credit payments during 2021 and update your bank account information. More functionality will be added later this year that will allow you to:

  1. Update your mailing address;
  2. Add or subtract the number of your qualifying children, including by reason of the birth or adoption of a child;
  3. Report a change in your marital status; and
  4. Report a change in your income.

If you would like to have your payment direct deposited, but don’t have an account, many financial institutions will help you open a low-cost or no-cost bank account. Visit the Federal Deposit Insurance Corporation website for details on opening an account online or use the FDIC's BankFind tool to locate an FDIC-insured bank. BankOn, American Bankers Association, Independent Community Bankers of America, National Credit Union Administration have lists of banks and credit unions that can open an account online.

More details will be provided regarding CTC UP through these questions and answers.

A2. Yes, if you provide your updated income by using the Child Tax Credit Update Portal (CTC UP). Later in 2021, this online portal will allow you to update income you plan to report on your 2021 tax return so that we can change our estimate of your 2021 Child Tax Credit. This will allow us to change the amount of your monthly advance Child Tax Credit payments. More details will be provided regarding CTC UP through these questions and answers.

A3. Your first advance Child Tax Credit payments will be based on the children you claimed for the Child Tax Credit on your 2020 tax return (or 2019 tax return, if your 2020 tax return has not been processed as of the payment determination date for any of your monthly advance Child Tax Credit payments).

Later this year, the Child Tax Credit Update Portal (CTC UP) will be updated to allow you to inform us about the qualifying children you will claim on your 2021 tax return so that we can adjust your estimated 2021 Child Tax Credit – and therefore adjust the amount of your monthly advance Child Tax Credit payments.

If you do not receive advance Child Tax Credit payments for a qualifying child you will claim in 2021, you may claim the full amount of your allowable Child Tax Credit for that child when you file your 2021 tax return.

More details will be provided regarding CTC UP through these questions and answers.

A4. The Child Tax Credit Update Portal (CTC UP) will allow you to unenroll from receiving advance Child Tax Credit payments. More details will be provided regarding CTC UP through these questions and answers.

A5. Beginning in July 2021, the IRS started making advance monthly payments of the 2021 Child Tax Credit to taxpayers.  For many taxpayers, the amount of the 2021 Child Tax Credit also has increased compared to the amount of the 2020 Child Tax Credit.  However, the total advance payments may be greater than any increase in the 2021 credit, depending on a taxpayer’s circumstances.  For taxpayers in this situation who do nothing in 2021 to adjust income tax withholding from their pay (and do not unenroll from advance monthly payments), the amount of their tax refund received in 2022 may decrease compared to the refund received in 2021, or the balance due in 2022 with their 2021 income tax return may increase compared to the balance due in 2021.  Some taxpayers also may shift from getting a refund in 2021 to owing a balance in 2022.

Therefore, taxpayers who received a small refund or had a balance due when they filed their tax return for 2020 in 2021 should consider unenrolling from advance Child Tax Credit payments, updating their Form W-4 by entering an additional amount to be withheld each pay period on step 4c of the form, or making quarterly estimated tax payments for the remainder of 2021.
