Child Tax Credit 2026: $2,200 Amount, Limits, How to Claim

Quick Answer: 2026 Child Tax Credit

The Child Tax Credit (CTC) for tax year 2026 is worth up to $2,200 per qualifying child under age 17, with up to $1,700 per child refundable as the Additional Child Tax Credit (ACTC). Single filers with adjusted gross income (AGI) up to $200,000 get the full credit, as do joint filers up to $400,000. Above those numbers, the credit drops by $50 for every $1,000 of extra AGI.

The One Big Beautiful Bill Act (P.L. 119-21, Sec. 70104) made the $2,200 amount permanent and tied it to inflation. You claim the credit on Form 1040 with Schedule 8812. To see how it fits with your full federal return, use the Tax Calculator US app.

What Is the Child Tax Credit for 2026?

The Child Tax Credit is a federal tax credit that lowers your tax bill (and may add to your refund) for each qualifying child under 17. For tax year 2026, the maximum credit is $2,200 per child, and up to $1,700 per child is refundable as the Additional Child Tax Credit.

These figures come from Section 70104 of the One Big Beautiful Bill Act (P.L. 119-21), signed into law on July 4, 2025. The law did three things at once: it made the $2,200 amount permanent rather than letting it revert to $1,000 after 2025, it locked in the $1,700 refundable cap, and it tied both numbers to inflation starting after tax year 2025. The IRS confirmed the 2026 figures in IR-2025-103.

Year-over-year comparison

Why no bump from 2025 to 2026? The indexing rule in IRC Section 24(i)(2) rounds inflation adjustments down to the nearest $100. Inflation in the relevant period was not large enough to push the indexed value past the next $100 step, so 2026 sits flat at $2,200. The first indexed increase will appear in a later year.

When does "tax year 2026" actually matter?

Tax year 2026 covers income earned from January 1 to December 31, 2026, and the return is filed in early 2027. If you adjust your W-4 mid-2026 to account for the credit, you are working with the 2026 number. If you are filing right now, you are filing for tax year 2025.

Who Qualifies: The Six Tests for a Qualifying Child

To claim the $2,200 Child Tax Credit, the child must pass all six of these tests under IRC Section 24(c). Miss one and the child does not qualify, although they may still trigger the smaller $500 Credit for Other Dependents.

1. Age: The child must be under 17 at the end of the tax year. For tax year 2026, that means age 16 or younger on December 31, 2026. A child who turns 17 during 2026 does not qualify for the full CTC, even if they were 16 for most of the year.
2. Relationship: Your son, daughter, stepchild, foster child, sibling, half-sibling, step-sibling, or a descendant of any of these (such as a grandchild, niece, or nephew). Adopted children count the same as biological children.
3. Residency: The child must have lived with you for more than half of 2026 (generally at least 183 nights). Temporary absences for school, medical care, or military service still count as time at home.
4. Support: The child must not have provided more than half of their own financial support during the year.
5. Dependent status: You must be able to claim the child as a dependent on your return, and they cannot file a joint return except to claim a refund of withheld tax.
6. Citizenship and SSN: The child must be a U.S. citizen, U.S. national, or U.S. resident alien, and must have a Social Security number valid for employment, issued before the due date of your return (including extensions).

The 2025+ parent SSN rule

Beginning with tax year 2025, OBBBA tightened the SSN requirement on the parent side as well. To claim the CTC, the taxpayer (or at least one spouse on a joint return) must also have a Social Security number valid for employment. Households that file with an Individual Taxpayer Identification Number (ITIN) for the parent no longer qualify for the $2,200 credit, even if the child has a valid SSN. They may still qualify for the $500 Credit for Other Dependents.

2026 Income Limits and How the Phase-Out Works

The Child Tax Credit is fully available up to a generous AGI threshold, then phases out gradually. The thresholds are not tied to inflation, so they are the same for 2026 as in prior years.

How the phase-out math works

Above the threshold, the total credit (across all your qualifying children) drops by $50 for every $1,000 of AGI, or fraction thereof. That works out to a 5% phase-out rate. Round up any partial $1,000.

So a single filer with $215,500 AGI is $15,500 over the threshold. Round up to 16 thousand-dollar increments. The credit drops by 16 x $50 = $800.

Where the credit fully zeroes out

Because each child adds $2,200 of credit, families with more children take longer to phase out. Use this table to find your zero-credit AGI:

The full $2,200 per child requires AGI at or below the starting threshold ($200,000 single, $400,000 MFJ). Anything above that produces a partial credit, and once you are above the zero point in the table, the credit goes to $0. Run your full return through the Tax Calculator US app to see how the phase-out interacts with the rest of your taxes.

Refundable vs. Nonrefundable: The $1,700 ACTC Explained

The Child Tax Credit has two parts: a nonrefundable portion (worth up to $2,200 per child against your tax bill) and a refundable portion called the Additional Child Tax Credit (ACTC), capped at $1,700 per child for 2026. The refundable portion is what makes the credit valuable to families with low or moderate income who already owe little or no federal tax.

The ACTC formula

The refundable ACTC is the smaller of these three amounts, per IRC Section 24(d):

1. The unused portion of the regular CTC after it has wiped out your tax liability.
2. 15% of your earned income above $2,500. This is the "phase-in" formula.
3. $1,700 per qualifying child (the statutory refundable cap for 2026).

You need at least $2,500 of earned income to receive any refundable amount, and the 15% phase-in means lower-earning families do not get the full $1,700 per child even if they have several kids.

The earned-income trap for low earners

Take a single parent with two children earning $15,000. The 15% phase-in produces 15% x ($15,000 - $2,500) = $1,875. That is the most they can receive as ACTC, regardless of how many children they have. They miss most of the potential $3,400 refundable amount because their earned income simply is not high enough.

The same parent earning $25,000 would generate 15% x ($25,000 - $2,500) = $3,375, which is just below the $3,400 two-child cap. By $25,167 in earned income, they unlock the full refundable amount.

Earned income definition

For the ACTC, earned income includes wages, salaries, tips, self-employment net earnings, and certain disability payments. It does not include unemployment benefits, Social Security, pensions, child support, or investment income. For self-employed filers, the deductible employer-equivalent portion of self-employment tax reduces earned income before the 15% calculation.

The $500 Credit for Other Dependents

If your dependent does not qualify for the $2,200 CTC, they may still qualify for the $500 Credit for Other Dependents (ODC) under IRC Section 24(h)(4). Common situations where the ODC applies:

• Children age 17 to 18. A child who is 17 or 18 at year-end fails the CTC age test but is still a qualifying child for general dependency purposes.
• Full-time students age 19 to 23. A college-age dependent who lived with you and meets the support test.
• Qualifying relatives. Parents, grandparents, in-laws, or other relatives you support, regardless of age.
• Dependents with ITINs. A child or other dependent who has an ITIN rather than an SSN can produce the $500 credit but not the $2,200 CTC.

Key rules for the ODC

• $500 maximum per dependent, fully nonrefundable.
• Same phase-out as the CTC: $200,000 single / $400,000 MFJ, reduced by $50 per $1,000 of AGI above the threshold.
• The dependent must be a U.S. citizen, U.S. national, or U.S. resident alien.
• You cannot claim both the CTC and the ODC for the same dependent in the same year.

How to Claim: Schedule 8812 Step-by-Step

You claim the Child Tax Credit on Schedule 8812 (Credits for Qualifying Children and Other Dependents), attached to Form 1040, 1040-SR, or 1040-NR. Tax software handles this automatically once you enter your dependents and earned income, but it helps to know what the schedule is doing under the hood.

Step 1: List your dependents on Form 1040

Each dependent goes in the dependents section of Form 1040 with name, SSN (or ITIN), relationship, and a check in either the "Child tax credit" column or the "Credit for other dependents" column. The right box must be checked or the credit will not appear in your return.

Step 2: Schedule 8812 Part I

Part I computes the total credit:

• Line 1: AGI from Form 1040.
• Lines 4-5: Number of qualifying children x $2,200.
• Lines 6-7: Number of other dependents x $500.
• Lines 9-12: AGI phase-out using the $200,000 / $400,000 thresholds.
• Line 14: Smaller of the credit or your remaining federal income tax. This nonrefundable amount flows to Form 1040, line 19.

Step 3: Schedule 8812 Part II-A (refundable ACTC)

Part II-A computes the refundable ACTC:

• Line 16a: Earned income.
• Line 16b: Earned income minus $2,500 (the phase-in floor).
• Line 17: 15% of line 16b.
• Line 18: $1,700 x number of qualifying children (the refundable cap).
• Line 19-27: Compares the smaller of (1) the unused CTC, (2) the 15% phase-in, and (3) the $1,700-per-child cap. The result flows to Form 1040, line 28 as a refundable credit.

Common errors that delay refunds

• Wrong SSN or missing SSN-by-due-date. The child's SSN must be issued before your return due date (including extensions). A late-issued SSN disqualifies the child for that year.
• Both parents claim the same child. Only one taxpayer can claim a given child in a year. The IRS uses tiebreaker rules and may reject the second-filed return.
• Box not checked on Form 1040. Even with a valid dependent listed, missing the CTC or ODC checkbox produces a $0 credit until you amend.
• Math error on Schedule 8812. The phase-out calculation and the three-way ACTC minimum trip up paper filers most often. Use software, or use the Tax Calculator US app to model the credit before you file.

Refund timing under the PATH Act

Returns claiming the ACTC are subject to the PATH Act hold: by law, the IRS cannot release a refund containing the refundable Child Tax Credit before mid-February. Most early-filing families with direct deposit see their refund by the first week of March.

These examples apply the 2026 statutory amounts ($2,200 max, $1,700 refundable cap, $200K/$400K phase-out, $2,500 earned-income floor, 15% phase-in) to common family scenarios. Run your own numbers through the Tax Calculator US app to see how the CTC interacts with your full federal return.

Frequently Asked Questions

Tips for Claiming the Child Tax Credit in 2026

• Confirm SSNs are issued by the return due date. A child or parent SSN that arrives after April 15, 2027 (or the extended due date) disqualifies that year's credit. Apply early at the Social Security Administration if a number is still pending.
• Check the right box on Form 1040. Each dependent must have either the "Child tax credit" or "Credit for other dependents" checkbox marked. A correct return without the box checked produces a $0 credit until you amend.
• Adjust your W-4 to reflect the credit. If you expect a $4,400 credit and your withholding does not account for it, you are loaning the IRS money interest-free until you file. Use the IRS Tax Withholding Estimator or the Tax Calculator US app to right-size your withholding.
• Track earned income if you are self-employed. The 15% ACTC phase-in uses earned income net of the deductible portion of self-employment tax. Underreporting your Schedule C income may save self-employment tax but cuts your refundable CTC.
• If divorced, get Form 8332 in writing. The default rule gives the credit to the custodial parent. If your divorce or separation agreement assigns the credit to the noncustodial parent, file Form 8332 every year it applies.
• Run a what-if return before December 31. Year-end income decisions (Roth conversions, year-end bonuses, capital-gains harvesting) can push your AGI past the $200,000 or $400,000 threshold and start eating into the credit. Model the impact in advance.
