Child Tax Credit Calculator: Filing season for the 2026 tax year will look different for millions of American families, and not just because of a bigger number on the return. The Child Tax Credit 2026 is now permanently set at up to $2,200 per qualifying child, locked in by the One Big Beautiful Bill Act that President Trump signed into law in July 2025 — but that same law also imposed a stricter Social Security number requirement that tax analysts estimate could exclude roughly 2 million children who previously qualified, many of them U.S. citizens living in mixed-status households.
Before this law, the credit was scheduled to fall back to just $1,000 per child once the 2017 Tax Cuts and Jobs Act provisions expired at the end of 2025 — a cliff that would have hit tens of millions of families simultaneously. Instead, the One Big Beautiful Bill Act made the higher credit amount permanent and indexed it to inflation going forward, avoiding that drop entirely. But it paired that increase with a new rule requiring the taxpayer claiming the credit, and their spouse if filing jointly, to have a valid, work-eligible Social Security number — a change that didn’t exist under the credit’s prior structure and that immigration and tax policy groups say will reshape who actually benefits from this larger number. We’ll be updating this article monthly as new IRS guidance, inflation adjustments, or legislative changes are announced.
Child Tax Credit 2026
For the 2026 tax year, the maximum Child Tax Credit remains $2,200 per qualifying child under age 17, the same amount that applied for 2025. While the One Big Beautiful Bill Act calls for the credit to be indexed for inflation starting in 2026, rounded down to the nearest $100, inflation hasn’t yet pushed the calculated amount above the current $2,200 threshold, so the figure holds steady for a second consecutive year. Of that total, up to $1,700 per child is refundable through the Additional Child Tax Credit, meaning families can receive that portion even if they owe little or no federal income tax.

Who Qualifies for the Child Tax Credit in 2026
The IRS applies several specific tests to determine whether a child qualifies a taxpayer for the credit, and missing even one disqualifies that dependent from the full Child Tax Credit, though a smaller credit may still apply. To qualify, a child must be under age 17 at the end of the tax year, must have lived with the taxpayer for more than half the year, and the taxpayer must have provided more than half of the child’s financial support during that time. The child must also be claimed as a dependent on the taxpayer’s return and generally must be a U.S. citizen, U.S. national, or U.S. resident alien.
The Core Child Tax Credit Eligibility Tests
- Age test — the child must be under 17 at the end of the tax year
- Relationship test — must be your son, daughter, stepchild, foster child, sibling, or a descendant of any of these
- Residency test — the child must have lived with you for more than half the year
- Support test — the child cannot have provided more than half of their own financial support
- Dependent test — the child must be claimed as a dependent on your tax return
- Citizenship test — the child must be a U.S. citizen, national, or resident alien
- Social Security number test — both the child and the taxpayer claiming the credit must have valid, work-eligible SSNs
- Joint return test — the child generally cannot file a joint tax return for the year, except to claim a refund

What Actually Changed: The New SSN Requirement Explained
The most consequential shift in the 2026 Child Tax Credit isn’t the dollar amount — it’s who’s now allowed to claim it. Under the credit’s prior rules, only the qualifying child needed a valid Social Security number; a parent filing with an Individual Taxpayer Identification Number (ITIN) instead of an SSN could still claim the credit for an SSN-holding child. The One Big Beautiful Bill Act eliminated that pathway. Starting with the 2025 tax year and continuing into 2026, the taxpayer claiming the credit — and their spouse, if filing a joint return — must also have a valid, work-eligible Social Security number.
That change has a direct and, according to tax policy analysts, unequal impact. Because the new rule applies to the parent rather than the child, it can disqualify U.S. citizen children from receiving the credit if their parent files taxes using an ITIN rather than an SSN — a scenario common in mixed-status households where children are citizens by birth but one or both parents are not authorized to work in the U.S. The Tax Policy Center’s original analysis of the provision, based on an earlier version of the bill with a $2,500 credit amount, estimated the SSN restriction could exclude roughly 2 million children with valid SSNs, the majority of them U.S. citizens, from a credit they would otherwise have qualified for.
Credit for Other Dependents: The Fallback Option
Families whose dependents don’t meet every Child Tax Credit requirement — including children who don’t have a qualifying SSN, or dependents who are 17 or older, such as college-age children or elderly relatives — may still be eligible for the smaller, nonrefundable Credit for Other Dependents, worth up to $500 per dependent. Unlike the full Child Tax Credit, the Credit for Other Dependents does not carry the same strict SSN requirement for the dependent, making it in some cases the only credit available to a family affected by the new parental SSN rule, even though it’s worth substantially less than the full $2,200 credit.
How the Income Phase-Out Actually Works
The Child Tax Credit doesn’t disappear all at once for higher earners — it phases out gradually. For 2026, the credit begins reducing once a taxpayer’s modified adjusted gross income exceeds $200,000 for single filers or $400,000 for married couples filing jointly. Beyond that threshold, the credit is reduced by 5% of the excess income, or $50 for every $1,000 above the limit, applied per $1,000 increment of income over the threshold.
Example: A single parent with modified adjusted gross income of $220,000 and one qualifying child is $20,000 over the $200,000 threshold. That excess reduces the credit by $50 for each $1,000 over the limit, or $1,000 total (20 x $50), bringing their credit down from $2,200 to $1,200.
Example: A married couple filing jointly with $450,000 in income and two qualifying children is $50,000 over the $400,000 threshold. That reduces their combined credit by $2,500 (50 x $50), lowering their total credit from $4,400 to $1,900.
Child Tax Credit Phase-Out Reference Table
| Filing Status | Phase-Out Begins | Reduction Rate |
|---|---|---|
| Single, Head of Household, Married Filing Separately | $200,000 MAGI | 5% of income over threshold |
| Married Filing Jointly | $400,000 MAGI | 5% of income over threshold |
Child Tax Credit Calculator
Use this calculator to estimate your 2026 Child Tax Credit based on your number of qualifying children, filing status, and modified adjusted gross income. This is a planning estimate only and does not account for every individual tax circumstance — confirm your actual credit using IRS Schedule 8812 or with a tax professional.
How to Claim the Child Tax Credit?
The Child Tax Credit is claimed when filing your annual federal tax return, using Schedule 8812 attached to Form 1040. There’s no separate application process or portal — eligible families claim the credit directly through their tax return, whether filed independently, through tax software, or with a paid preparer. Because the SSN requirement now extends to the taxpayer as well as the child, filers should confirm well before tax season that every required SSN on the return is valid and correctly entered, since a mismatch can delay processing or result in the credit being denied for that dependent.

Processing Time and Payment Schedule
The Child Tax Credit isn’t paid out as a monthly advance the way it briefly was during the temporary 2021 expansion — for 2026, it’s applied entirely at tax filing time, either reducing the amount owed or increasing a refund. The IRS is legally required to hold refunds that include the Additional Child Tax Credit until at least mid-February, a rule intended to give the agency additional time to verify income and prevent fraudulent claims. Filers claiming the refundable portion should expect their refund to arrive later than filers without dependents, even if they file on the very first day of the season, and should plan their household budgeting accordingly.

FAQs
How much is the Child Tax Credit for 2026?
The Child Tax Credit for 2026 is worth up to $2,200 per qualifying child under age 17, with up to $1,700 of that amount refundable through the Additional Child Tax Credit.
Did the Child Tax Credit change under the One Big Beautiful Bill Act?
Yes. The law made the higher $2,200 credit amount permanent, indexed it for inflation starting in 2026, and added a new requirement that the taxpayer claiming the credit (and their spouse, if filing jointly) must have a valid Social Security number, in addition to the existing requirement for the child.
Can I claim the Child Tax Credit if I file with an ITIN?
No. Starting with the 2025 tax year, taxpayers filing with an Individual Taxpayer Identification Number instead of a Social Security number can no longer claim the Child Tax Credit, even if their child has a valid SSN.
What happens if my child doesn’t have a Social Security number?
A child without a valid SSN doesn’t qualify for the Child Tax Credit, but may still be eligible for the smaller, nonrefundable Credit for Other Dependents, worth up to $500.
At what income does the Child Tax Credit start phasing out?
The credit begins phasing out at $200,000 in modified adjusted gross income for single filers and $400,000 for married couples filing jointly, reduced by 5% of income over that threshold.
Is the Child Tax Credit paid monthly in 2026?
No. Unlike the temporary 2021 expansion, the 2026 Child Tax Credit is claimed entirely when filing your annual tax return rather than through monthly advance payments.
How many children could lose the Child Tax Credit because of the new SSN rule?
Tax Policy Center estimates suggest the SSN requirement could exclude roughly 2 million children with valid Social Security numbers, most of whom are U.S. citizens in mixed-status households, from receiving the credit.
Conclusion
The Child Tax Credit 2026 delivers real, permanent stability for most American families — a $2,200-per-child credit that’s no longer at risk of reverting to $1,000 as it was under prior law — but it arrives paired with a new eligibility barrier that didn’t exist before. The requirement that taxpayers themselves hold a valid Social Security number, not just their children, marks a meaningful shift in who can access the credit, with estimates suggesting millions of U.S. citizen children in mixed-status households could be affected. For most filers, the bigger practical question this tax season will simply be how the income phase-out and refundable Additional Child Tax Credit apply to their own household — questions best confirmed directly through IRS Schedule 8812 or a qualified tax preparer before filing. We’ll be updating this article monthly as new IRS guidance, inflation adjustments, or legislative changes to the Child Tax Credit are announced.
