Child Tax Credit for 2026: Amounts, Income Limits, and How to Claim
The 2026 Numbers
The CTC is the most consequential tax credit on the individual return for families with kids —. And the rule everyone misremembers. Let’s start with the figures that matter for tax year 2026:
- $2,200 per qualifying child under age 17 at the end of the year
- Up to $1,700 refundable per child via the Additional Child Tax Credit (ACTC)
- $500 nonrefundable Credit for Other Dependents (ODC) for dependents who don’t qualify for the CTC
- Phase-out begins at $200,000 AGI single / $400,000 AGI MFJ, reducing $50 per $1,000 over the threshold
Those are the four headline numbers. Everything else on this page is mechanics and edge cases.
Who Qualifies as a “Qualifying Child”
The IRS uses seven tests under IRC § 24. The child has to clear every one of them. Miss any single test and the credit is gone for that child.
- Age: Under 17 at year-end. A child who turns 17 on December 31, 2026 fails the test. One who turns 17 on January 1, 2027 passes.
- Relationship: Son, daughter, stepchild, foster child, sibling, step-sibling, or descendant of any of these.
- Residency: Lived with you more than half the year. Temporary absences for school, medical care, or military service still count as time with you.
- Support: The child didn’t pay for more than half of their own support during the year.
- Citizenship: U.S. citizen, U.S. national, or U.S. resident alien.
- SSN: The child must have a valid Social Security number issued by the due date of the return, including extensions.
- Joint return: The child didn’t file a joint return for the year (or filed only to claim a refund).
OBBBA added a parallel rule on the parent side: the taxpayer claiming the credit must also have a valid SSN (or, in the case of an adopted child, an ATIN works for the dependent in limited cases). An ITIN-only filer can no longer claim the CTC. That’s a real change from prior law and worth flagging for mixed-status households.
The Phase-Outs and a Worked Example
The credit phases out at the same thresholds the TCJA set in 2018: $200,000 modified AGI for single, head of household, and married filing separately, and $400,000 for married filing jointly. For every $1,000 (or fraction of $1,000) of income above the threshold, you lose $50 of credit per return.
Here’s the math on a $450,000 MFJ household with two qualifying children. The starting credit is $4,400. Income exceeds the $400,000 threshold by $50,000. Divide by $1,000 and round up if needed: 50 increments. Multiply by $50: $2,500 reduction. Final credit: $4,400 minus $2,500 equals $1,900.
For one child at $440,000 MFJ, you’d lose $2,000 of the $2,200 credit, leaving $200. Push income to $444,000 and the credit is gone. Most households earning under $350,000 won’t feel the phase-out at all —. Which is the whole point of the bill that Congress kept in place.
Refundability and the ACTC
The credit has two parts. They land on your return differently.
The nonrefundable portion reduces your tax dollar-for-dollar but stops at zero. If you owe $1,500 and have $2,200 in credit, the first $1,500 erases your tax. The remaining $700 doesn’t disappear —. It potentially flows to the Additional Child Tax Credit, which is refundable.
The ACTC formula is 15% of earned income above $2,500, capped at $1,700 per child for 2026. Worked example: a single parent earning $25,000 with one child. Earned income above $2,500 is $22,500. Multiply by 15%: $3,375. That exceeds the $1,700 cap, so the parent gets the full $1,700 refundable amount. A parent earning $8,000 gets 15% of $5,500, which is $825 —. That’s the cap on their ACTC, not $1,700.
The 15%-of-earned-income-above-$2,500 formula is what makes the credit reach families who don’t earn enough to owe federal income tax. Without it, the CTC would be a middle-class benefit only.
The $500 Credit for Other Dependents
The ODC covers dependents who fail one of the qualifying child tests but still meet the broader dependency rules. Common cases: a 17-year-old still in high school, a college-age son or daughter you support, an elderly parent who lives with you and has minimal income, or a qualifying relative whose gross income is below the annual limit.
It’s $500 per dependent and uses the same $200,000 / $400,000 phase-out thresholds. The ODC was introduced under the TCJA in 2018 and was set to disappear after 2025 along with the higher CTC. OBBBA kept it permanent. For families with college-age kids, this is often the credit that keeps something on the return after a child ages out of the CTC at 17.
The OBBBA Story
For most of 2025, families and tax preparers planned for the worst-case scenario. Under the TCJA’s sunset clause, on January 1, 2026 the child tax credit would have reverted to $1,000 per child. The phase-out thresholds would have collapsed to $110,000 MFJ and $75,000 single. A married couple earning $130,000 with two kids would have lost the entire credit. Families across the income spectrum were looking at a tax increase that ranged from a few hundred dollars to several thousand.
Then the One Big Beautiful Bill Act passed. P.L. 119-21, signed July 4, 2025, did three things to the CTC. It made the higher credit permanent (no more sunset). It bumped the per-child amount from $2,000 to $2,200, indexed for inflation. It kept the $400,000 / $200,000 phase-outs and the $500 ODC. The earned-income floor for ACTC refundability also dropped slightly, from $3,000 to $2,500. None of this is temporary —. It’s the law from now on unless Congress changes it again.
Common Mistakes
The credit is straightforward in theory. The errors are almost always in the details.
- SSN issued after the deadline. If your child’s SSN doesn’t arrive until after April 15 and you didn’t file an extension, you’ve blown the credit for that year. File Form 4868 for the extension. The SSN deadline becomes October 15.
- Confusing ATIN with ITIN. An ATIN (Adoption Taxpayer Identification Number) can work in limited adoption situations. An ITIN doesn’t qualify a child for the CTC under any circumstance.
- Half-time custody coin flips. Only one parent claims a child per year. The default is the parent with more nights during the calendar year, even if it’s 183 versus 182. Plan it. Don’t fight about it on April 14.
- Year-of-divorce confusion. If you divorce mid-year, custody nights are counted from the date custody was established, not the full year. Form 8332 lets a custodial parent release the claim to the noncustodial parent —. Useful when the noncustodial parent has higher income and benefits more from the credit.
- Phase-out math without rounding. The reduction is $50 per $1,000 (or fraction). $400,500 MFJ income isn’t $25 of reduction —. It’s $50, because any portion of a $1,000 increment counts.
- Software using stale numbers. Some early-2026 software still defaults to $2,000. If you see that figure on Schedule 8812, pause and update.
How to Claim the Credit
You report the credit on Form 1040, line 19 (nonrefundable portion) and line 28 (refundable ACTC). The detailed calculation runs through Schedule 8812. Each child needs to be listed on the 1040 with name and relationship. The SSN has to match Social Security Administration records exactly —. Transposed digits trigger an electronic rejection.
For background on the broader return mechanics, see how Form 1040 returns work. If you’re choosing between standard and itemized, the credit applies either way — standard versus itemized doesn’t change CTC eligibility.
Planning Around the Credit
If you’re near the $400,000 MFJ threshold, AGI management is worth the effort. Maxing a 401(k), making HSA contributions, or deferring a bonus to next year can shift you under the line. At $50 per $1,000 of AGI reduction, every $10,000 you shift saves $500 of credit. Two kids, two phase-outs in motion, and the savings can hit four figures.
New parents should review their W-4 once the SSN arrives. The IRS withholding estimator handles the credit automatically —. Updating it means smaller refunds at filing and bigger paychecks now. For a starter overview, see becoming a parent: tax basics. For a fuller picture across deductions and credits, our tax strategy guides walk through the planning angles year by year.
The CTC story for 2026 isn’t about whether the credit exists. It does, at $2,200 per child, with an indexed adjustment coming in future years. The story is whether your return captures every dollar of it — SSNs in on time, phase-out math correct, refundable portion not left on the table. Get the details right and the credit does its job.

Frequently Asked Questions
How much is the child tax credit for 2026?
For 2026, the child tax credit is currently set at $1,000 per qualifying child under age 17 — that’s the baseline amount written into current law under IRC Section 24, assuming Congress doesn’t act before the Tax Cuts and Jobs Act (TCJA) provisions expire at the end of 2025. If TCJA sunsets as scheduled, the credit drops from the $2,000 per child that taxpayers have enjoyed since 2018. The refundable portion, sometimes called the Additional Child Tax Credit, would also revert to older limits.
Here’s what most people are missing: if lawmakers extend or modify the TCJA before year-end 2025, those numbers could change dramatically — possibly staying at $2,000 or even increasing. The refundability threshold matters too. Under current post-TCJA rules, up to $1,700 (indexed for inflation) is refundable in 2024, meaning you can get money back even if you owe nothing. That refundable floor drops to $1,000 under pre-TCJA rules, and the earned income calculation changes as well. Watch the phase-out thresholds too: $400,000 for married filers and $200,000 for single filers under TCJA, versus $110,000 married and $75,000 single under the old rules.
At The Reed Corporation, we keep a close eye on tax legislation so our NYC clients don’t get caught off guard at filing time. If you’re planning your 2026 budget or payroll withholding, it’s worth scheduling a quick check-in so we can run your numbers under both scenarios and help you plan so.
What are the income limits for the child tax credit in 2026?
The income limits for the child tax credit in 2026 depend heavily on whether Congress extends the TCJA provisions. Under TCJA rules (which technically expire after 2025), the phase-out begins at $400,000 of modified adjusted gross income (MAGI) for married filing jointly and $200,000 for all other filers. The credit reduces by $50 for every $1,000 of income above those thresholds. If the TCJA sunsets without renewal, the phase-out drops back to $110,000 for married filers and $75,000 for single filers — a massive difference for middle-income families in high-cost cities like New York.
The phase-out math sounds simple, but the ‘what most people miss’ part is how other income sources factor into your MAGI. Things like rental income, self-employment income, or a one-time stock sale can push you over the threshold even in a year when your W-2 wages haven’t changed. Also, New York State doesn’t have its own child tax credit that mirrors the federal version dollar-for-dollar — the Empire State Child Credit is a separate calculation, worth up to $333 per child or 33% of the federal credit, whichever is greater, and it has its own income structure.
If you’re close to one of these thresholds, there are legitimate planning strategies — like maximizing 401(k) contributions to reduce MAGI — that can preserve the credit. The Reed Corporation reviews this as part of our year-round planning process for clients, not just at tax time.
Who qualifies as a qualifying child for the child tax credit?
To claim the child tax credit, your child has to meet six tests defined under IRC Section 152 and Section 24: age (under 17 at the end of the tax year), relationship (your child, stepchild, foster child, sibling, or a descendant of any of them), residency (lived with you for more than half the year), dependency (claimed as your dependent), financial support (the child didn’t provide more than half their own support), and citizenship (a U.S. citizen, U.S. national, or U.S. resident alien). Miss any one of these and you’re disqualified, even if the child lived with you all year.
The age cutoff trips people up constantly. The child must be under 17 — not 17 or under. So a child who turns 17 on December 31st doesn’t qualify for that tax year. Divorced or separated parents also face a specific wrinkle: only the custodial parent (the one the child lived with longer during the year) can claim the credit by default. The custodial parent can release that right using Form 8332, but the child tax credit — unlike the dependency exemption — cannot be transferred to the noncustodial parent. That’s a detail family law attorneys and CPAs often have to sort out together.
It’s a distinction that causes real headaches during tax season, especially in shared-custody situations. The Reed Corporation works with a lot of divorced clients in New York and has helped many of them figure out the cleanest way to handle dependency and credits between two returns.
How do I claim the child tax credit on my tax return?
You claim the child tax credit on your Form 1040, and the calculation runs through Schedule 8812 (Credits for Qualifying Children and Other Dependents). You’ll enter each qualifying child’s name, Social Security number, and relationship on the main 1040 form. Schedule 8812 then walks you through the credit amount, the phase-out calculation if your income is above the threshold, and whether you qualify for the refundable Additional Child Tax Credit portion. Every qualifying child must have a valid Social Security number issued before the due date of your return — an ITIN doesn’t cut it for the child tax credit.
One thing that catches people off guard: advance child tax credit payments were issued in 2021, and the IRS sent out Letter 6419 to reconcile them. We’re not in that regime anymore, but the IRS does cross-reference SSNs against their records. If there’s a mismatch — say, a child’s SSN is entered incorrectly or was recently updated after a name change — the credit gets rejected and you’ll need to respond to an IRS notice. Also, if you’re self-employed and filing a Schedule C, your net earnings affect your earned income calculation for the refundable portion, which flows through Schedule 8812 lines 6a through 8.
Filing Schedule 8812 correctly sounds straightforward, but errors here are one of the more common audit triggers the IRS flags for automated review. At The Reed Corporation, we prepare these schedules carefully and review SSNs against prior-year records so nothing slips through.
Will the child tax credit go back to $1,000 in 2026 if nothing changes?
Yes — under current law, the child tax credit reverts to $1,000 per qualifying child starting in tax year 2026 if Congress doesn’t act. The Tax Cuts and Jobs Act doubled the credit from $1,000 to $2,000 per child, but that provision has a built-in expiration date of December 31, 2025. So unless there’s new legislation, families will see their per-child credit cut in half starting with returns filed for the 2026 tax year (typically due April 15, 2027). The refundable Additional Child Tax Credit also changes under the old rules, dropping back toward $1,000 with a different earned income formula.
The honest answer is that nobody knows for certain what Congress will do. There’s been bipartisan support for extending at least some version of the enhanced credit, and proposals have ranged from a full TCJA extension to targeted expansions aimed at lower-income families. But ‘proposed’ and ‘passed’ are very different things. If TCJA does sunset, the phase-out thresholds drop significantly — from $400,000 to $110,000 for married couples — which means even moderate-income families in expensive metro areas like New York City could lose access to the credit entirely. That’s a swing of up to $2,000 per child in after-tax dollars.
Planning for two possible outcomes sounds annoying, but it’s genuinely the right call right now. The Reed Corporation is tracking legislative developments closely and we’re proactively reaching out to clients whose credit amounts could shift meaningfully depending on what passes.
