Understanding the 2027 Child Tax Credit: What Families Need to Know

For the 2027 tax year, families can expect the Child Tax Credit to be worth $2,300 for each qualifying child under the age of 17. Of this amount, up to $1,800 per child can be received as a refund through the Additional Child Tax Credit (ACTC). These figures represent an increase from the 2026 tax year, when the credit was $2,200 and the refundable portion was capped at $1,700. While the credit amounts have been adjusted for inflation, other key aspects of the credit, such as income limitations and Social Security number requirements, remain unchanged by law.

How the 2027 Credit Amounts Are Determined

The current structure of the Child Tax Credit is largely shaped by the One Big Beautiful Bill Act, signed into law in July 2025. This legislation made the $2,200 credit permanent starting with the 2025 tax year, preventing a scheduled reduction. It also introduced a new inflation adjustment rule for the credit amount.

Two distinct indexing rules influence the credit and its refundable portion:

• Credit Amount: The credit begins at $2,200 and is adjusted annually for inflation using the chained consumer price index, with 2024 as the base year. Any increase that is not a full $100 is rounded down to the nearest $100.
• Refundable Cap: The refundable portion, known as the Additional Child Tax Credit (ACTC), starts from a statutory $1,400. This amount has been indexed against 2017 prices since a 2018 law, leading to its increase to $1,700 for 2025 and 2026. This cap also rounds down to the nearest $100.

For 2027, the credit amount has risen to $2,300, and the refundable cap is now $1,800. It is important to note that the refundable portion can never exceed the total credit amount itself. Several other figures related to the credit, such as the $500 Credit for Other Dependents, the $2,500 earned-income floor for refunds, and the income phase-out thresholds, are fixed by statute and do not adjust for inflation.

Understanding the Value of the 2027 Credit for Your Family

The maximum Child Tax Credit a family can claim is calculated by multiplying the per-child amount by the number of qualifying children, and then adding $500 for each other dependent. For example, a family with two qualifying children could claim up to $4,600 for the 2027 tax year. With three children, this ceiling rises to $6,900.

This credit first works to reduce the amount of income tax a family owes. If the total credit is more than the tax liability, the excess amount can be refunded through the ACTC. However, this refund is capped at $1,800 per child and is also limited to 15% of the family’s earned income that exceeds $2,500. To receive the full refundable amount for one child, a parent would generally need around $14,500 in earned income. Families with three or more children may use an alternative calculation based on Social Security and Medicare taxes paid, detailed on Schedule 8812.

Income Limits and the Phase-Out

The Child Tax Credit begins to decrease once a family’s modified adjusted gross income (MAGI) surpasses certain thresholds. For single filers, heads of household, and married individuals filing separately, this threshold is $200,000. For those married filing jointly, the threshold is $400,000. These income limits are set by law and do not change with inflation.

The credit is reduced by $50 for every $1,000, or portion thereof, of MAGI that exceeds these thresholds. This reduction applies to the combined total of the Child Tax Credit and the Credit for Other Dependents. For a single parent with one child, the entire credit is lost once their MAGI reaches approximately $245,000. For a married couple filing jointly with one child, this cutoff is around $445,000. Each additional child increases these phase-out thresholds. MAGI includes adjusted gross income plus any income excluded by foreign earned income or housing exclusions.

The Social Security Number (SSN) Requirement for 2027

A critical rule for claiming the Child Tax Credit starting with the 2025 tax year requires that both the child and the taxpayer have valid Social Security numbers (SSNs). An SSN or Individual Taxpayer Identification Number (ITIN) issued after the tax return’s due date, including extensions, cannot be used for that tax year.

For the 2027 tax year, the following SSN rules apply:

• Child’s SSN: Each qualifying child must have a valid SSN.
• Taxpayer’s SSN: The person claiming the credit must also have a valid SSN. If filing jointly, only one spouse needs a valid SSN; the other can have an SSN or an ITIN issued by the return’s due date.

A “valid SSN” is one issued to a U.S. citizen or an individual authorized to work in the United States, and it must have been issued before the tax return’s due date. SSN cards marked “Not Valid for Employment” do not qualify.

If a child does not meet the SSN requirement but has an ITIN or Alien Taxpayer Identification Number (ATIN) issued by the due date, they may still qualify for the $500 Credit for Other Dependents. This credit is nonrefundable and can only reduce the tax owed.

How Immigrant and Visa-Holder Families Qualify

Immigration status plays a significant role in determining eligibility for the Child Tax Credit. Tax residency is a key factor, with green card holders and most work-visa holders (like H-1B and L-1) generally considered tax residents once they meet the substantial presence test.

• Green Card Holders: Those with SSNs qualify under the same terms as U.S. citizens, provided their children also have valid SSNs.
• H-1B Workers and H-4 Spouses: The H-1B worker’s SSN satisfies the taxpayer SSN requirement for a joint return, even if their H-4 spouse only has an ITIN. A U.S.-born child with an SSN is eligible for the full credit.
• Children on H-4 or L-2 Visas: These children often hold ITINs as they may not be work-authorized. They typically do not qualify for the Child Tax Credit but can qualify for the $500 Credit for Other Dependents if they are resident aliens and dependents.
• Parents with Only ITINs: Families where both parents have only ITINs cannot claim the Child Tax Credit or ACTC, even if their child is a U.S. citizen with an SSN. However, that child may still qualify the family for the $500 Credit for Other Dependents.
• Nonresident Aliens (Form 1040-NR): Generally, nonresident aliens cannot claim the credit. Exceptions exist for residents of Canada and Mexico, U.S. nationals, and, with limitations, for residents of South Korea and certain students and business apprentices under the U.S.-India tax treaty.

It is crucial for families needing tax identification numbers for a spouse or child to apply well in advance. An ITIN or SSN issued after the return’s due date cannot be used to claim the credit for that year, even on an amended return.

Children Living Abroad

The Child Tax Credit has specific rules for children living outside the United States. A qualifying child must have lived with the taxpayer for more than half of the tax year. Temporary absences for reasons like school, vacation, or medical care are considered time lived together.

A child living abroad with other relatives, such as grandparents, generally fails the residency test. Furthermore, the child must be a U.S. citizen, U.S. national, or a U.S. resident alien. Children living abroad who are not U.S. citizens typically do not meet this requirement. The $500 Credit for Other Dependents also has limitations for dependents living in Canada or Mexico.

U.S. citizen families residing abroad together can claim the credit, as the child lives with them. However, if a taxpayer files Form 2555 to claim the foreign earned income exclusion, they cannot claim the refundable portion of the ACTC. The nonrefundable portion of the credit may still be used to offset U.S. tax liability.

Claiming the 2027 Credit on Schedule 8812

To claim the Child Tax Credit for the 2027 tax year, families must file Schedule 8812 (Form 1040), Credits for Qualifying Children and Other Dependents, along with their 2027 Form 1040 or 1040-SR. On the Dependents section of Form 1040, taxpayers should check the “Child tax credit” box for each child with a valid SSN or the “Credit for other dependents” box for a dependent who only qualifies for the $500 credit. A single dependent cannot be claimed under both categories.

Key steps for claiming the credit include:

1. Confirm Ages: Ensure children born in 2011 or later are under 17 at the end of 2027. Children born in 2010 will turn 17 during 2027 and may qualify for the $500 Credit for Other Dependents instead.
2. Verify SSNs: Check all SSN cards against the work-authorization rules. If a child’s status has changed, request a corrected card from the Social Security Administration.
3. Apply for IDs Early: Submit applications for any missing SSNs or ITINs well before the tax return deadline in April 2028.
4. Maintain Proof of Residence: Keep records, such as school or medical documents, that show each child’s address. The IRS may request this proof.
5. Anticipate Refund Timing: By law, the IRS cannot issue refunds that include the ACTC until mid-February. This hold applies to the entire refund amount.

Families who had their credit denied in a previous year may need to file Form 8862 with the IRS to have it reinstated.

Actions to Take Now

• Update Your W-4: If the 2027 Child Tax Credit affects your tax situation, adjust your Form W-4 to ensure your paycheck withholding is accurate. Step 3 of the form is where you account for qualifying children.
• Secure SSNs for Newborns: Request an SSN for any newborn at the hospital during the birth registration process, as this is typically faster than applying later.
• Address ID Gaps: Resolve any issues with missing or incorrect SSNs or ITINs for family members before the tax return due date to avoid losing the credit.
• Manage Income Near Phase-Out Limits: If your MAGI is close to the $200,000 or $400,000 thresholds, consider strategies like contributing to pre-tax 401(k)s or Health Savings Accounts (HSAs) to lower your MAGI and potentially preserve more of your credit.
