IRS Publication 5534 – IRS Forms, Instructions, Pubs 2026 – IRS Publication 5534 (Rev. 10-2021), titled An Overview of the 2021 Advance Child Tax Credit Payments, is the official IRS document that explains the temporary advance payment program created by the American Rescue Plan Act of 2021. This one-time expansion of the Child Tax Credit (CTC) helped millions of families receive financial relief during the COVID-19 pandemic by delivering up to half of their 2021 CTC as monthly payments from July through December 2021.
If you’re searching for details on IRS Publication 5534, how the 2021 advance Child Tax Credit payments worked, eligibility rules, payment amounts, or reconciliation requirements, this article provides a clear, accurate summary based directly on the official IRS publication and current IRS.gov resources (last reviewed October 2025).
What Is IRS Publication 5534?
Published in October 2021 (Catalog Number 38425P), Publication 5534 served as a plain-language guide for taxpayers. It answered the most common questions about the new advance CTC program, including:
- Who qualified for monthly payments
- How much families could receive
- When and how payments were issued
- Options to opt out
- What to do if you hadn’t filed recent tax returns

Background: The 2021 Enhanced Child Tax Credit
For tax year 2021 only, the American Rescue Plan dramatically expanded the CTC:
- Maximum credit rose to $3,600 per qualifying child under age 6 (at end of 2021)
- Maximum credit rose to $3,000 per qualifying child ages 6–17
- The credit became fully refundable (available even to families with little or no earned income)
- Payments were issued in advance — half the estimated credit sent monthly, with the remainder claimed when filing the 2021 tax return
Publication 5534 emphasized that these changes applied only to 2021 and that advance payments were an early distribution of the credit taxpayers would ultimately claim on their 2021 return.
Eligibility for 2021 Advance Child Tax Credit Payments
According to IRS Publication 5534 and supporting guidance, you (and your spouse, if filing jointly) generally qualified if you:
- Had a qualifying child who was under age 18 at the end of 2021 with a valid Social Security number
- Lived in the United States for more than half of 2021 (or your spouse did, on a joint return)
- Filed a 2019 or 2020 tax return claiming the CTC, or provided information via the Non-Filer Sign-Up Tool in 2020 or 2021
Key point from the publication: Most families who filed their 2020 return did not need to take any action — payments started automatically on July 15, 2021.
Non-filers were urged to use the IRS Non-Filer Sign-Up Tool (available until October 15, 2021) to register for both advance CTC payments and any remaining Economic Impact Payments.
2021 Advance Child Tax Credit Payment Amounts and Schedule
Publication 5534 clearly outlined the monthly advance amounts (up to 50% of the full 2021 credit):
| Child’s Age (at end of 2021) | Full 2021 CTC Amount | Monthly Advance Payment | Total Advance (6 months) |
|---|---|---|---|
| Under age 6 | Up to $3,600 | Up to $300 | Up to $1,800 |
| Ages 6–17 | Up to $3,000 | Up to $250 | Up to $1,500 |
Payments were issued on these dates in 2021:
- July 15
- August 13
- September 15
- October 15
- November 15
- December 15
Payments arrived by direct deposit (preferred) or paper check.
How to Unenroll or Update Information?
The publication informed taxpayers they could opt out of advance payments entirely using the Child Tax Credit Update Portal if they preferred to claim the full credit when filing their 2021 return. The portal also allowed updates to bank information, address changes, or adding/removing qualifying children.
Note (2026 update): The Child Tax Credit Update Portal is no longer available. Advance payment totals are now viewable in your IRS online account.
Reconciliation: Claiming the Remaining 2021 Child Tax Credit
Advance payments represented roughly half the credit. When filing the 2021 Form 1040, taxpayers had to reconcile:
- Total advance CTC payments received (reported on Letter 6419, mailed by the IRS in January 2022)
- Actual CTC amount you qualified for on your 2021 return (using Schedule 8812)
- If you received less in advances than you qualified for → claim the difference as a refundable credit
- If you received more → the excess reduced your refund or increased tax owed
Current status (as of 2026): The deadline to file a 2021 return and claim any remaining 2021 CTC was April 15, 2025 (or later with extension). Publication 5534-H (Rev. 2-2023) reminded taxpayers that even those with no income could file to claim the credit.
