Child Tax Credit 2026: Who Qualifies & How Much

For the 2026 tax year, the Child Tax Credit is worth up to $2,200 per qualifying child under age 17, with up to $1,700 of that refundable even if you owe little or no federal income tax. The credit phases out for single filers earning above $200,000 and married couples filing jointly above $400,000, reducing by $50 for every $1,000 of income over that threshold.

This amount is locked in for the foreseeable future thanks to the One Big Beautiful Bill Act (OBBBA), signed into law on July 4, 2025 — a detail that matters more than it might seem, since without that legislation, the credit was scheduled to drop back to just $1,000 per child starting in 2026. This guide walks through exactly who qualifies, how the phase-out actually works, what changed under OBBBA, and how to claim the credit correctly on your return.

Quick Answer: What the 2026 Child Tax Credit Is Worth

Before the details, here's the number that matters most: $2,200 per qualifying child, non-refundable up to your tax liability, with up to $1,700 refundable through the Additional Child Tax Credit if the non-refundable portion exceeds what you owe. A married couple filing jointly with two qualifying children can claim up to $4,400 total, with as much as $3,400 of that potentially refundable depending on their tax liability and earned income.

This figure applies specifically to tax year 2026 and reflects the permanent increase established by OBBBA — up from the $2,000 amount that had been in place since 2018 under the Tax Cuts and Jobs Act (TCJA).

What Changed for 2026: The OBBBA Story

Understanding why the 2026 credit looks the way it does requires a quick bit of legislative context, since a lot of families spent much of 2025 bracing for a very different outcome.

The TCJA, passed in 2017, temporarily raised the Child Tax Credit from $1,000 to $2,000 per child and expanded the phase-out thresholds significantly, but those provisions were written with a sunset clause — meaning without further legislative action, the credit was set to revert back to its pre-2018 levels ($1,000 per child, with phase-out thresholds collapsing to roughly $110,000 for married couples and $75,000 for single filers) starting in tax year 2026.

The One Big Beautiful Bill Act, signed on July 4, 2025, changed that outcome entirely. Rather than simply extending the $2,000 TCJA amount, OBBBA:

• Raised the credit to $2,200 per qualifying child, a $200 increase over the prior TCJA-era amount
• Made this amount permanent, removing the sunset risk that had families and tax preparers planning for a much smaller credit
• Kept the higher phase-out thresholds permanent at $200,000 (single) and $400,000 (married filing jointly), avoiding the steep drop to pre-2018 thresholds
• Added inflation indexing going forward, so the credit amount can adjust upward in future years rather than staying fixed
• Introduced a new Social Security number requirement for the taxpayer claiming the credit, not just the qualifying child

It's worth being direct about one thing OBBBA did not do: it did not restore the temporary 2021 American Rescue Plan expansion, which had briefly raised the credit to $3,000–$3,600 per child with monthly advance payments. That expansion expired after 2021, and OBBBA's changes — while a meaningful permanent increase — are distinct from and smaller than that temporary pandemic-era program.

Who Qualifies: The Full Eligibility Checklist

The IRS applies several specific tests a child must meet to count as a "qualifying child" for this credit. All of these need to be satisfied — missing even one disqualifies that child for the credit, though they may still qualify you for the smaller Credit for Other Dependents instead.

That last requirement is one of the more consequential additions under OBBBA, since it specifically affects mixed-status families where a parent may not have a Social Security number even if their child does. This is a meaningful eligibility change worth understanding fully if it applies to your household, and it's worth confirming your specific situation directly with a tax professional or the IRS's Child Tax Credit guidance given how much turns on this one detail.

How Much You Actually Get: Income Phase-Out Explained

The full $2,200-per-child credit isn't available at every income level. Here's exactly how the phase-out works.

Full credit available if your Modified Adjusted Gross Income (MAGI) is:

• $200,000 or less (single, head of household, or married filing separately)
• $400,000 or less (married filing jointly)

Above those thresholds, the credit reduces by $50 for every $1,000 (or part of $1,000) your MAGI exceeds the limit. For a family with one qualifying child, this means the credit phases out completely once income reaches roughly $240,000 (single) or $440,000 (married filing jointly) — though the exact cutoff shifts slightly depending on how many children you're claiming, since the phase-out reduction scales with the total credit amount.

Worked Example: How the Phase-Out Reduction Is Calculated

Say a married couple filing jointly has two qualifying children and a MAGI of $450,000:

1. Base credit: $2,200 × 2 children = $4,400
2. Excess income over threshold: $450,000 − $400,000 = $50,000
3. Number of $1,000 increments: $50,000 ÷ $1,000 = 50
4. Reduction: 50 × $50 = $2,500
5. Final credit: $4,400 − $2,500 = $1,900

If the reduction calculation exceeds the total credit amount, the credit is simply reduced to zero — it doesn't go negative or offset other credits.

The Refundable Portion: Additional Child Tax Credit (ACTC) Explained

This is one of the most misunderstood parts of the Child Tax Credit, so it deserves its own clear explanation. The Child Tax Credit is partially non-refundable and partially refundable, and the distinction matters enormously depending on your tax situation.

A non-refundable credit reduces your tax liability, but only down to zero — it can't generate a refund beyond what you actually owed. If your tax bill is smaller than your available credit, the non-refundable portion simply can't help you further on its own.

The Additional Child Tax Credit (ACTC) is the refundable piece that fills this gap. For 2026, up to $1,700 per qualifying child can be received as a refund even if your tax liability is zero, provided you meet the earned income requirement.

How the Refundable Portion Is Calculated

The ACTC isn't automatically the full $1,700 — it's calculated as the smaller of two figures:

• $1,700 per qualifying child, or
• 15% of your earned income above $2,500

This means very low earned income can limit how much of the credit is actually refundable, even if you have multiple qualifying children. A family needs meaningful earned income — wages, self-employment income — for this calculation to unlock the full refundable amount, which is why the ACTC is sometimes described as a "phase-in" credit at the lower end of the income scale, separate from the phase-out that happens at the higher end.

Credit for Other Dependents: What If My Dependent Doesn't Qualify for the CTC?

Not every dependent meets the strict qualifying child test for the full Child Tax Credit — a 17-year-old who's aged out, a full-time college student under 24, a disabled dependent of any age, or a qualifying relative you support financially can still generate a tax benefit through the Credit for Other Dependents (ODC).

The ODC is worth $500 per dependent, is entirely non-refundable, and uses the same $200,000/$400,000 phase-out thresholds as the main Child Tax Credit. It's a smaller benefit, but it's often the credit that keeps something meaningful on a family's return once a child ages out of the CTC at 17 — a detail that catches parents of teenagers off guard more often than you'd expect.

How to Claim the Child Tax Credit

Claiming the credit happens through your annual federal tax return, using two specific forms:

1. Form 1040 — your standard individual income tax return, where you list your qualifying children and dependents.
2. Schedule 8812 — the specific form used to calculate your Child Tax Credit, Additional Child Tax Credit, and Credit for Other Dependents based on your income, number of qualifying children, and earned income.

The IRS uses the information on Schedule 8812 to determine your non-refundable credit amount first, applying it against your tax liability, and then calculates any remaining refundable ACTC amount separately based on the 15%-of-earned-income formula. Most tax preparation software walks through this calculation automatically once you've entered your dependents and income correctly, but understanding the underlying math helps you spot an error if the number on your return looks off from what you expected.

Divorced or Separated Parents: Who Claims the Credit?

This is one of the most common points of confusion, and the rule is more specific than many people realize: only one parent can claim a child for the Child Tax Credit in a given tax year, even in shared custody situations. Generally, the custodial parent — the one the child lived with for the greater number of nights during the year — has the right to claim the credit.

However, the custodial parent can release this claim to the non-custodial parent using IRS Form 8332, which is common in divorce or separation agreements that alternate which parent claims the child each year. Without this form properly filed, the non-custodial parent generally cannot claim the credit, regardless of what a private custody agreement states, since IRS rules take precedence over the terms of a divorce decree alone for this specific purpose.

If two parents mistakenly both attempt to claim the same child, the IRS will flag the duplicate claim, generally awarding the credit to whichever parent meets the residency test, and the other return may face delays, an audit inquiry, or a requirement to amend.

Child Tax Credit vs. Similar Credits: Avoiding Confusion

The Child Tax Credit sits alongside several other family-related tax benefits, and mixing them up is a common mistake.

Notably, the Child and Dependent Care Credit also saw enhancements under OBBBA for 2026 — the maximum credit rate rose from 35% to 50% of qualifying expenses for the lowest-income taxpayers, and the Dependent Care FSA contribution limit increased from $5,000 to $7,500, the first change to that limit since 1986 outside of a temporary pandemic-era bump. These are separate benefits from the Child Tax Credit, but many families qualify for both simultaneously.

State-Level Child Tax Credits: A Separate Layer

Beyond the federal credit, several states run their own independent child tax credit programs, which stack on top of (not instead of) the federal benefit. These state credits vary significantly in amount, eligibility, and whether they're refundable, and they change frequently based on individual state budgets and legislation. If you live in a state with its own program, it's worth checking your specific state's department of revenue for current figures rather than assuming the federal rules apply identically, since state programs often have entirely different income thresholds and per-child amounts.

For the federal side specifically, if you're trying to estimate your total tax picture including the Child Tax Credit alongside your regular income tax liability, an income tax calculator can help you see how the credit interacts with your overall return, and this broader guide on standard vs. itemized deductions for 2026 is useful context if you're planning your full return rather than just this one credit in isolation.

Common Mistakes That Cost Families Part of Their Credit

• Missing the SSN requirement. Both the child and the claiming taxpayer need valid Social Security numbers issued before the return's due date — an ITIN doesn't satisfy this requirement for the taxpayer under OBBBA's rules.
• Assuming a 17-year-old still qualifies. The age cutoff is strict — a child who turns 17 at any point during the tax year no longer qualifies for the full CTC for that year, though they may qualify for the $500 Credit for Other Dependents instead.
• Both parents attempting to claim the same child without a properly filed Form 8332, which triggers IRS processing delays for both returns.
• Underestimating the earned income requirement for the refundable portion. Families with very low earned income may receive less of the ACTC than expected, since it's capped at 15% of earned income above $2,500, not simply handed out as a flat $1,700 regardless of income.
• Confusing the CTC with the temporary 2021 expansion. The $3,000–$3,600 per-child amounts from the American Rescue Plan expired after 2021 and are not part of the current 2026 rules — relying on outdated information from that period leads to inflated expectations.

Frequently Asked Questions

Who qualifies for the Child Tax Credit in 2026? A child qualifies if they're under 17 at year-end, related to you as a son, daughter, stepchild, foster child, or similar relationship, lived with you more than half the year, didn't provide more than half their own support, and has a valid Social Security number. The taxpayer claiming the credit must also have a valid SSN under new OBBBA rules.

How much is the Child Tax Credit per child in 2026? The credit is worth up to $2,200 per qualifying child under 17, with up to $1,700 of that amount refundable through the Additional Child Tax Credit if your tax liability doesn't fully absorb the non-refundable portion.

What is the income limit to claim the Child Tax Credit? The full credit is available up to $200,000 MAGI for single filers and $400,000 for married couples filing jointly. Above those thresholds, the credit phases out by $50 for every $1,000 of income over the limit.

Is the Child Tax Credit refundable? Partially. Up to $1,700 per child is refundable through the Additional Child Tax Credit, calculated as the smaller of $1,700 or 15% of your earned income above $2,500. The remaining portion is non-refundable and can only offset actual tax liability.

How old does a child need to be to qualify? The child must be under age 17 at the end of the tax year — meaning 16 or younger. A child who turns 17 during the tax year no longer qualifies for the Child Tax Credit for that year, though they may qualify for the smaller $500 Credit for Other Dependents.

Can I claim the Child Tax Credit for a child without a Social Security number? No. Under current rules, the qualifying child must have a valid Social Security number issued before the tax return's due date. This is a firm requirement, not a preference.

What is the difference between the Child Tax Credit and Additional Child Tax Credit? The Child Tax Credit is the full $2,200-per-child benefit, which is primarily non-refundable and reduces your tax liability. The Additional Child Tax Credit is specifically the refundable portion (up to $1,700 per child) that can generate a refund even if you owe little or no federal tax.

How do I claim the Child Tax Credit on my tax return? You claim the credit on Form 1040, using Schedule 8812 to calculate the exact non-refundable and refundable amounts based on your income, number of qualifying children, and earned income.

Final Takeaway

The 2026 Child Tax Credit — $2,200 per qualifying child, with up to $1,700 refundable — represents a meaningful and, thanks to OBBBA, now permanent improvement over what families were bracing for heading into this tax year. The eligibility rules are specific but manageable: age under 17, valid Social Security numbers for both child and claiming taxpayer, residency and support tests, and awareness of where the income phase-out starts to reduce your benefit.

If you're preparing your 2026 return and want to see exactly how this credit interacts with your broader tax liability, running your numbers through an income tax calculator before filing gives you a clearer picture than estimating the Child Tax Credit in isolation — especially if your income sits anywhere near the $200,000 or $400,000 phase-out thresholds where the math genuinely matters.
