Child Tax Credit 2026: How Much, Eligibility & How to Claim

CTC 2026 Amounts at a Glance

The table below summarizes every component of the family credits available for the 2026 tax year. Understanding the difference between refundable and non-refundable matters enormously for low- and middle-income families.

The $500 non-refundable portion means a family with zero federal tax liability cannot benefit from that piece — only the $1,700 ACTC flows back as a refund check. This structural gap is why the Tax Policy Center estimates 17 million children in low-income families still do not receive the full credit.

What Changed Under the One Big Beautiful Bill Act (OBBBA)

The OBBBA (Public Law 119-21), signed on July 4, 2025, made several permanent changes to the Child Tax Credit that affect every family filing a 2025 or 2026 return. Before the OBBBA, the expanded CTC parameters from the Tax Cuts and Jobs Act of 2017 were scheduled to expire ("sunset") after 2025, which would have reverted the credit to $1,000 per child. The OBBBA eliminated that cliff entirely.

The Four Core OBBBA Changes

• Credit amount increased to $2,200: Up from $2,000 per qualifying child. This is the first statutory increase to the base CTC in nearly a decade and applies starting with the 2025 tax year (returns filed in 2026).
• Indexed to inflation: Starting with the 2026 tax year, the $2,200 base amount adjusts annually with the Consumer Price Index. Future increases are rounded down to the nearest $100. This means the credit will not erode silently as prices rise — a major structural improvement.
• Phase-out thresholds made permanent: The $200,000 (single) and $400,000 (married filing jointly) thresholds are now permanent. Previously they would have reverted to $75,000/$110,000 at the TCJA sunset — which would have eliminated the credit for tens of millions of middle-class families.
• New SSN requirement for refundable ACTC: To claim the refundable Additional Child Tax Credit, at least one parent or taxpayer on the return must have a work-authorized Social Security Number. This does not affect the non-refundable portion but significantly impacts mixed-status households.

Approximately 90% of families with children receive some form of the CTC, according to the Tax Policy Center. The OBBBA ensures that benefit does not disappear after 2025 — which is the biggest practical impact for most filers.

Complete Eligibility Requirements (All 7 Tests)

To claim the Child Tax Credit for a qualifying child, that child must pass all seven IRS tests. Failing even one test disqualifies the child from the CTC (though they may still qualify for the $500 Other Dependent Credit).

Test 1: Age

The child must be under age 17 at the end of the tax year. For the 2025 return (filed in 2026), that means born on or after January 1, 2009. A child born on December 31, 2025 qualifies for the full 2025 CTC — the IRS treats the child as having lived with you for the entire year. A child who turns 17 on any date in 2025 does not qualify.

Test 2: Relationship

Qualifying relationships include your son, daughter, stepchild, eligible foster child, brother, sister, stepbrother, stepsister, half-brother, half-sister, or a descendant of any of these (grandchildren, nieces, nephews). An adopted child is treated the same as a biological child.

Test 3: Residency

The child must have lived with you for more than half the year — more than 183 nights. Temporary absences for school, vacation, medical care, or detention count as time living with you. For divorced or separated parents, the custodial parent (the one with whom the child lived more nights) generally claims the credit. However, the custodial parent can release the dependency to the non-custodial parent using Form 8332. The non-custodial parent then attaches Form 8332 to their return to claim the CTC.

Test 4: Support

The child must not have provided more than half of their own financial support during the year. This is rarely an issue for children under 17, but if a teenager earns substantial income from a job, this test can come into play. Support includes food, shelter, clothing, medical care, and education costs.

Test 5: Citizenship

The child must be a U.S. citizen, U.S. national, or U.S. resident alien. Children who are resident aliens must have lived in the U.S. for more than half the year. Non-resident alien children do not qualify for the CTC even if they have an SSN.

Test 6: Social Security Number

The child must have a valid Social Security Number issued by the Social Security Administration before the due date of the return (including extensions). An Individual Taxpayer Identification Number (ITIN) does not qualify for the CTC. Children with ITINs may still qualify for the $500 Other Dependent Credit, but not the $2,200 CTC. This requirement has existed since the TCJA and was not changed by the OBBBA.

Test 7: Dependency

You must claim the child as a dependent on your return. A child cannot be claimed as a dependent on more than one return (except under the divorced parent exception via Form 8332). If you are a non-custodial parent claiming the credit via Form 8332, make sure the custodial parent has formally released the dependency for that tax year.

Income Phase-Out: Who Gets Full Credit, Partial, or None

The CTC reduces when your modified adjusted gross income (MAGI) exceeds the threshold for your filing status. The reduction is $50 for every $1,000 (or fraction thereof) over the threshold.

Worked example: A married couple with two children earns $420,000. Their income exceeds the $400,000 threshold by $20,000. The reduction is $50 per $1,000, so $50 × 20 = $1,000 reduction. Their CTC goes from $4,400 (2 × $2,200) to $3,400.

MAGI for CTC purposes is generally the same as your adjusted gross income on Form 1040. It does not add back most deductions. Use our income tax calculator to estimate your MAGI and projected CTC amount before you file.

The Additional Child Tax Credit (ACTC) — The Refundable Portion

The most valuable aspect of the CTC for lower-income families is the refundable ACTC. If your CTC exceeds the federal income tax you owe, the ACTC lets you receive the excess — up to $1,700 per child — as a cash refund. This means families with little or no tax liability can still benefit substantially.

ACTC Calculation Formula

The ACTC equals 15% of your earned income above $2,500, capped at $1,700 per qualifying child. Earned income includes wages, salaries, tips, and net self-employment income — it does not include investment income, Social Security, unemployment, or alimony.

Worked Example

A single parent earning $32,000 has one qualifying child. Their federal income tax after the standard deduction is $800. The CTC is $2,200. First, the $2,200 credit reduces the $800 tax liability to $0, leaving $1,400 of unused CTC. Next, the ACTC is calculated: ($32,000 − $2,500) × 15% = $29,500 × 15% = $4,425. Since $4,425 is more than the unused $1,400, the ACTC is limited to the unused amount: $1,400. The parent receives a $1,400 refund from the ACTC on top of any withholding refund.

Now consider a family earning just $12,000 with two children. Their ACTC calculation: ($12,000 − $2,500) × 15% = $9,500 × 15% = $1,425. Even though they have two children (max ACTC of $3,400), their low earned income caps the actual refund at $1,425. This formula is why the Tax Policy Center finds 17 million children in low-income families do not receive the full benefit — their earned income simply does not generate enough ACTC.

PATH Act Delay

Under the Protecting Americans from Tax Hikes (PATH) Act, the IRS cannot issue refunds that include the ACTC before mid-February, regardless of when you file. This delay exists to give the Social Security Administration time to verify SSNs and prevent fraud. If you file in late January, expect your ACTC refund to arrive no earlier than approximately February 15.

New SSN Rules — A Critical Change for Immigrant Families

The OBBBA introduced a new requirement that significantly affects mixed-immigration-status households: at least one parent or guardian on the tax return must have a work-eligible Social Security Number (one that permits employment in the United States) to claim the refundable ACTC.

This affects several family configurations:

• Both parents have ITINs: Cannot claim the ACTC. May still claim the non-refundable CTC up to their tax liability if their child has a valid SSN.
• One parent has SSN, one has ITIN (filing jointly): The SSN-holding parent satisfies the requirement; the family can claim the full ACTC.
• Single parent with ITIN, child has SSN: Cannot claim the ACTC. Child still qualifies for the non-refundable CTC.
• Child has ITIN, parent has SSN: Child does not qualify for the CTC at all (child SSN requirement is unchanged). May qualify for the $500 ODC.

Tax professionals and immigrant advocacy organizations estimate this rule affects several hundred thousand families. If you are in a mixed-status household, review your specific situation carefully before filing. See IRS Publication 972 for the complete rules on SSN requirements.

How to Claim the CTC on Your Return (Schedule 8812)

The Child Tax Credit is claimed using IRS Schedule 8812 — Credits for Qualifying Children and Other Dependents. This schedule is attached to your Form 1040 and walks through three calculations: the non-refundable CTC, the refundable ACTC, and the Other Dependent Credit.

Step-by-Step Filing Process

1. List your qualifying children on Form 1040: Include each child's name, SSN, and relationship in the Dependents section. The SSN must match SSA records exactly — a mismatch will cause the IRS to disallow the credit and trigger a notice.
2. Complete Part I of Schedule 8812: This section determines which children qualify. You enter each child's birthdate and confirm the SSN was issued by the return due date.
3. Calculate the non-refundable CTC (Part II): Multiply the number of qualifying children by $2,200. Apply the phase-out reduction if your income exceeds the threshold. Reduce this amount by your federal tax liability — the remainder (up to your tax bill) is the non-refundable credit.
4. Calculate the ACTC (Part III): If the non-refundable CTC does not fully absorb your $2,200 per child, compute the ACTC: 15% of earned income above $2,500, not to exceed $1,700 per qualifying child. Enter the result on Form 1040 Schedule 3, Line 6d.
5. Claim the Other Dependent Credit (Part II, separate line): For dependents who do not qualify for the CTC (age 17+, or those with ITINs), the $500 ODC is calculated separately in the same section.

Most major tax software (TurboTax, H&R Block, FreeTaxUSA, TaxAct) completes Schedule 8812 automatically when you enter your dependents. If you are filing taxes manually or using fillable forms, download Schedule 8812 from IRS.gov and use the instructions carefully — the phase-out worksheet is easy to miscalculate by hand. Avoid common filing mistakes by double-checking every SSN digit before you submit.

Child and Dependent Care Credit — A Separate, Stackable Benefit

Many families confuse the Child Tax Credit with the Child and Dependent Care Credit (CDCC). They are entirely different credits, and you can claim both for the same child. The CDCC helps working parents offset the cost of childcare — daycare, after-school programs, summer day camps, and in-home nannies — so parents can work or look for work.

Under the OBBBA, the CDCC was enhanced for lower-income families: the credit rate for households with income below $15,000 now reaches up to 50% of qualifying care expenses, up from 35% previously. The average CDCC benefit for qualifying families is approximately $2,100.

Maximum qualifying expenses are $3,000 for one qualifying child or $6,000 for two or more. Both parents must have earned income — or one must be a full-time student — during the year. The CDCC is non-refundable, so it can reduce your tax to zero but does not produce a refund. It is claimed on Form 2441, and you must report the childcare provider's name, address, and Employer Identification Number or SSN.

If your employer offers a Dependent Care Flexible Spending Account (DCFSA), you can contribute up to $5,000 pre-tax. However, you cannot use the same expenses for both the FSA and the CDCC. You must reduce your CDCC qualifying expenses by whatever you excluded through the FSA. For high-income earners, the FSA is typically worth more than the CDCC due to the higher marginal tax bracket savings.

EITC + CTC: Stacking Credits for Low-Income Families

The ACTC and the Earned Income Tax Credit (EITC) can both be claimed on the same return — and together they represent the most powerful anti-poverty tool in the federal tax code. For a family with three children earning $40,000, the combined value of the EITC ($7,000+) and the ACTC (up to $5,100) can exceed $12,000 in refundable credits.

The EITC has its own eligibility rules and income limits — it phases in with earned income and then phases out at higher income levels. For the 2025 tax year, the maximum EITC with three or more children is approximately $7,830 for single filers earning below $56,838 ($63,398 for married filing jointly). Unlike the ACTC, the EITC is available even to workers with no children (though at much lower amounts).

Both credits are subject to the same SSN rules. The PATH Act delay applies to refunds containing either the EITC or ACTC — so if you claim both, your refund will not arrive before mid-February regardless of when you file. This is a common source of confusion for early filers who expect immediate processing.

One important nuance: both the CTC and EITC require earned income. If you are retired, living entirely on Social Security, or have only investment income, neither credit applies. This is a frequent misunderstanding — a high net worth retiree with minor grandchildren they support cannot claim the ACTC if they have no earned income.

Tax Planning Strategies for Families

The CTC is automatic once you file, but smart planning can increase the amount you receive — especially if you are near a phase-out threshold or want to maximize the refundable ACTC. These strategies are worth reviewing as part of your year-end tax planning.

1. Reduce MAGI to Stay Below Phase-Out Thresholds

If your income is close to $200,000 (single) or $400,000 (MFJ), pre-tax contributions can push your MAGI below the threshold. Contributing the maximum to a 401(k) ($23,500 for 2025, $31,000 if age 50+) reduces your MAGI dollar-for-dollar. A married couple earning $405,000 who each maximize their 401(k) would reduce MAGI to $358,000 — well below the $400,000 threshold — preserving the full CTC.

2. Optimize the ACTC With Earned Income

For very low-income families, every additional dollar of earned income above $2,500 generates 15 cents of ACTC per child. A family with two children and $10,000 of earned income receives ($10,000 − $2,500) × 15% × 2 = $2,250 in ACTC. Adding a side gig or part-time work increases this substantially, up to the $3,400 cap for two children. See our guide to tax credits vs deductions to understand why even small earned income gains matter so much here.

3. Coordinate the CDCC and Dependent Care FSA

If your employer offers a Dependent Care FSA, model both scenarios: (a) contribute $5,000 to the FSA and claim CDCC on remaining expenses, versus (b) skip the FSA and claim CDCC on all expenses. For income above $43,000, the FSA exclusion is almost always worth more because it saves your marginal rate (22–37%) on $5,000, while the CDCC only credits 20% of expenses.

4. Filing Status Matters for Phase-Out

Married filing jointly receives double the phase-out threshold ($400K vs. $200K). In most cases, joint filing preserves far more CTC value. However, in specific situations — such as when one spouse has very high income and the other has significant losses — separate filing might make sense. Review your filing status options carefully before assuming joint is always best.

5. Stack Education Credits for College Students

Once your child turns 17, the CTC ends — but the $500 Other Dependent Credit begins. If that same child is in college, you may also claim the American Opportunity Tax Credit (up to $2,500/year for the first four years of college) or the Lifetime Learning Credit. Review the full education tax credits guide to stack these benefits correctly.

6. Verify SSNs Before You File

One of the most common filing mistakes that triggers CTC disallowance is an SSN mismatch. Cross-reference each child's SSN against their Social Security card before entering it on the return. A transposed digit delays your entire refund and can require an amended return. The IRS will send CP87A or Letter 5747C if SSN verification fails.
