The Rule Changed — and Most Immigrant Families Do Not Know It Yet

For years, ITIN holders were a recognized part of the Child Tax Credit system. Many immigrant families claimed the credit, paid their taxes, and received a modest but meaningful refund for each child. That pathway has narrowed significantly.

The One Big Beautiful Bill, signed into law on July 4, 2025, made several permanent changes to the Child Tax Credit. The most consequential one for immigrant families: at least one parent on the return must now have a valid Social Security number to claim the $2,200 credit. An ITIN alone, for either the parent or the child, no longer gets you to the main credit.

That does not mean immigrant parents owe nothing and receive nothing. The rules are more nuanced than that, and there are still legitimate credits available depending on your household’s specific combination of SSNs and ITINs. But you need to understand exactly where you stand — because claiming the wrong credit, or missing the right one, has real dollar consequences.

This guide walks through every scenario: what the law now requires, which ITIN filers still qualify for something, how mixed-status families should file, and what to do if your child does not yet have an SSN.

The 2026 Child Tax Credit at a Glance

Before diving into the ITIN-specific rules, it helps to understand what the credit looks like in 2026 for families who meet all the requirements.

The maximum credit is $2,200 per qualifying child. This is a permanent increase from the previous $2,000 baseline, indexed to inflation going forward starting with the 2026 tax year. For a family with two children, the maximum credit is $4,400.

The refundable portion is $1,700 per child. The Child Tax Credit itself is non-refundable — meaning it can reduce your tax bill to zero, but not below. The Additional Child Tax Credit (ACTC) is the refundable portion: if your credit exceeds your tax liability, you can receive up to $1,700 per qualifying child as a refund, provided you have earned income of at least $2,500 and meet the other requirements.

Income phase-outs start at $200,000 for single filers and $400,000 for married couples filing jointly. Above those thresholds, the credit is reduced by $50 for every $1,000 of income above the limit. Many families are not affected by this.

You file Form 1040 and attach Schedule 8812. Schedule 8812 is the worksheet where the IRS calculates both the non-refundable CTC and the refundable ACTC. All claims flow through this form.

The SSN Requirement: What It Actually Means for Your Family

This is the section most immigrant families need to read carefully, because the rules are layered.

What the Law Now Requires

Under the rules in effect for tax year 2026, three separate SSN tests apply:

Test 1 — The parent’s SSN: At least one person filing the return must have a valid Social Security number that is valid for employment and issued before the due date of the return (April 15, 2027, or the extension deadline). On a joint return, only one spouse needs to meet this test; the other can use an ITIN.

Test 2 — The child’s SSN: The qualifying child must also have a valid work-authorized SSN issued before the due date of the return. A child with an ITIN does not qualify for the $2,200 CTC or the refundable ACTC.

Test 3 — Single filers with no SSN: If you are filing as a single person and you only have an ITIN — no SSN — you cannot claim the CTC or ACTC on your 2026 return.

Scenarios Broken Down

Understanding how these tests play out across common household situations is more useful than reading the rules in the abstract.

Scenario A — Both spouses have SSNs, child has SSN: Full credit available. You can claim up to $2,200 per qualifying child and up to $1,700 per child in refundable ACTC.

Scenario B — One spouse has SSN, other spouse has ITIN, child has SSN: Full credit available. The IRS only requires one spouse on a joint return to have a valid SSN. The ITIN-holding spouse does not disqualify the claim.

Scenario C — Both spouses have ITINs, child has SSN: No CTC or ACTC. Neither parent holds the required SSN. The child may still qualify for the $500 Credit for Other Dependents if the other tests are met — but the parents must also have valid ITINs issued before the return’s due date.

Scenario D — One or both spouses have SSNs, child has ITIN: No CTC or ACTC for that child. The child’s ITIN disqualifies them from the main credit. You may, however, claim the $500 Credit for Other Dependents for that child, provided they meet the other qualifying tests.

Scenario E — Single filer with ITIN, child has SSN: No CTC or ACTC. A single filer with only an ITIN cannot claim these credits, regardless of the child’s SSN status.

The takeaway: the single most important variable is whether at least one parent has a valid work-authorized SSN. If yes, and the child also has a valid SSN, the credit is fully available. If either piece is missing, you fall into a different category — and the Credit for Other Dependents becomes your primary tool.

The Credit for Other Dependents: The ITIN Filer’s Fallback

When your situation does not qualify for the full Child Tax Credit, the Credit for Other Dependents (ODC) is the credit designed for you. It is smaller — but it is real money, and many eligible families never claim it.

What Is the Credit for Other Dependents?

The Credit for Other Dependents (ODC) is a non-refundable credit worth up to $500 per qualifying dependent. It covers dependents who do not meet the requirements for the standard CTC — including children with ITINs rather than SSNs, children who are 17 or older, college-aged dependents up to age 24, and qualifying relatives such as parents or grandparents you support financially.

Non-refundable means the credit can reduce your tax liability to zero, but it will not generate a refund if you owe less than $500 per dependent. For families with meaningful tax bills, this is still a valuable dollar-for-dollar reduction.

Who Qualifies for the ODC?

To claim the ODC for a child, that child must:

  • Be claimed as a dependent on your return
  • Be a U.S. citizen, U.S. national, or U.S. resident alien
  • Have a valid taxpayer identification number — which can be an SSN, an ITIN, or an Adoption Taxpayer Identification Number (ATIN) — issued on or before the due date of your return
  • Not already qualify for the CTC or ACTC (the credits cannot stack on the same child)

To claim the ODC for yourself as the filer, you must also have a valid SSN or ITIN issued on or before the due date of your return. If neither you nor your spouse (on a joint return) has a qualifying TIN, you cannot claim the ODC either.

The Income Phase-Out for the ODC

The same income thresholds that apply to the CTC apply to the ODC: the credit begins to phase out above $200,000 for single filers and $400,000 for married couples filing jointly. The reduction is $50 per $1,000 of income above the threshold. For most families asking about ITIN-related credits, income is well below these limits.

Why the ODC Matters Even When It Feels Small

A $500 non-refundable credit per child may feel modest compared to the $2,200 CTC. But for an ITIN-filing family with two children who have ITINs, that is $1,000 in reduced tax liability. Over ten years of filing, it is $10,000 that stays in your family’s pocket rather than going to the IRS. The habit of claiming every credit you legally qualify for is not a small thing — it is a compounding financial practice.

How Mixed-Status Families Should Navigate Filing

“Mixed-status” is a common term for families where some members have SSNs and others have ITINs or no U.S. tax identification at all. These households face the most complex filing decisions, and the stakes of getting it wrong — in either direction — are high.

When One Spouse Has an SSN

If you are married filing jointly and one spouse has a valid work-authorized SSN while the other files with an ITIN, your filing position is better than many ITIN families realize.

For tax credits: you can claim the CTC and ACTC for any qualifying children who have valid SSNs. The one-SSN-on-the-return rule is satisfied. Children with ITINs in the same household would fall to the ODC.

For other considerations: having one spouse on a joint return with an SSN also affects your eligibility for the Earned Income Tax Credit (EITC), which has its own SSN requirements. Depending on your income and family size, the EITC may be worth exploring alongside the CTC — the two credits interact through Schedule 8812.

When Children Have Different Identification Numbers

It is not unusual for families where parents arrived before their children to have some children with SSNs (born in the U.S. or naturalized) and others with ITINs (born abroad and not yet naturalized). In this case, the credits are calculated per child:

  • Children with SSNs: claim the full $2,200 CTC and potentially the refundable ACTC
  • Children with ITINs: claim the $500 ODC instead

You attach a single Schedule 8812 to your return, but the math runs separately for each dependent category. Tax software handles this automatically; if you are filing by hand, read the Schedule 8812 instructions carefully to ensure you put each child in the correct column.

Applying for an SSN for Your Child

If your child was born in the United States, they are a U.S. citizen and eligible for a Social Security number — and obtaining one before you file should be a priority. A child who is born in the U.S. but has not yet received their SSN can have the application submitted at the hospital or at any Social Security Administration office.

The IRS has a specific rule for children born near the tax filing deadline: if your child was born in 2026 and you have applied for an SSN on or before the due date of your return, and the SSN is subsequently issued, the IRS will treat it as issued before the deadline. This means you should not delay applying — even a newborn born in late December may still qualify for the full CTC if you act quickly.

If Your Child Is Not a U.S. Citizen

A child who is a U.S. resident alien can still qualify for the CTC if they have a valid SSN. “Resident alien” for this purpose follows the same Substantial Presence Test described in immigration and tax residency guidance. If your child has lived in the United States for a sufficient period of time and passes the Substantial Presence Test, their resident alien status makes them CTC-eligible — provided they also have a valid SSN.

A child who is a non-resident alien does not qualify for the CTC under current rules.

The ITIN Renewal Warning: Do Not Miss This Step

An expired ITIN can cost you the entire ODC claim. This is one of the most preventable mistakes that ITIN-holding families make each filing season.

ITINs expire if they are not used to file a federal tax return for three consecutive years. They also expire on a rolling schedule if they were issued before 2013, based on the middle digits of the ITIN number. If your ITIN — or your dependent’s ITIN — has expired, the IRS will process your return but disallow any credit associated with the expired number.

To renew an ITIN, you submit Form W-7 to the IRS along with required identity documentation. Processing times for ITIN renewal can run 11 weeks or longer during filing season, so starting early matters. You can file your return with a renewal application in progress — you just need to have applied by the return’s due date. Renewing your own ITIN and your children’s ITINs before the tax year begins is the cleanest approach.

Check your ITIN status at irs.gov/itin before filing each year. If there is any doubt, renew proactively.

Filing the Right Forms: A Practical Walkthrough

Knowing which credits you qualify for is only half the task. Filing them correctly is the other half.

Form 1040 or 1040-NR

ITIN filers who are U.S. tax residents under the Substantial Presence Test file Form 1040, the same return as U.S. citizens. Non-resident aliens file Form 1040-NR. Note that the Child Tax Credit and the Credit for Other Dependents are both available on Form 1040, but the treatment on 1040-NR is more limited — non-resident aliens generally cannot claim the CTC, which is one of many reasons that your residency classification matters so much before you begin any return.

Schedule 8812

Schedule 8812 (Credits for Qualifying Children and Other Dependents) is attached to your Form 1040 and is where all child-related credit calculations happen.

Part I calculates the non-refundable Child Tax Credit and Credit for Other Dependents. You list each qualifying child and dependent, their TIN, and whether they have an SSN or ITIN — this determines which column they fall into and which credit applies.

Part II-A calculates the Additional Child Tax Credit for most filers. It applies the 15% formula to your earned income above $2,500 to determine how much of the remaining CTC you can receive as a refund.

Part II-B applies to filers with three or more qualifying children and provides an alternative calculation based on Social Security taxes paid — which can produce a larger refund in some situations.

Where Errors Typically Occur

The most common mistakes on ITIN-related returns involve mismatched identification numbers. The name and TIN on your return must exactly match what the IRS has on file. A transposed ITIN digit, a name mismatch, or an expired ITIN will cause the credit to be disallowed — often without a clear explanation until weeks after your return is processed.

Using tax software or a professional preparer with experience in immigrant returns is strongly recommended. Many free filing resources — including Volunteer Income Tax Assistance (VITA) sites — specialize in ITIN filer returns at no cost.

What Cannot Be Fixed After the Fact

Two specific errors on child tax credit returns carry lasting consequences that most filers do not know about.

Claiming a credit you are not entitled to through reckless disregard of the rules results in a two-year ban on claiming those credits, even in years where you would otherwise qualify. If the IRS determines the error was fraudulent, the ban extends to ten years.

Filing with an incorrect SSN for the child — for example, using an ITIN in the SSN field to attempt to claim the CTC — triggers disallowance of the credit. The IRS cross-checks SSNs against Social Security Administration records automatically. Errors of this kind are detected at the processing stage and can flag your return for review.

If you are uncertain about your eligibility, the correct move is to claim what you clearly qualify for — the ODC, in most ITIN situations — and to consult a qualified tax professional about more complex questions before filing, not after.

State Child Tax Credits: A Second Pathway Worth Checking

The federal CTC discussion is only part of the picture. Many states have their own child tax credits or dependent exemptions, and the state-level rules are often different from the federal rules — including, in some states, rules that are more favorable to ITIN filers.

States including California, New York, Colorado, and several others have enacted state-level child tax credits that may be available to ITIN filers regardless of the federal SSN requirements. California’s Young Child Tax Credit, for example, has historically been available to ITIN filers with children under six. New York provides a child credit that also has less stringent identification requirements.

If you live in a state with a state income tax, check your state’s revenue department website or consult a tax professional familiar with your state’s rules. The federal rules changed in 2025; your state’s rules may not have changed, and that difference is money you are owed.

Building a Practical Filing Plan

Most ITIN filers navigating these rules for the first time face the same set of questions. Here is a concrete priority order for addressing them before you file:

Step 1 — Check every ITIN in your household. Confirm that your ITIN and each dependent’s ITIN is active and matches IRS records. If any are expired, start the renewal process immediately using Form W-7.

Step 2 — Identify which children have SSNs. For each child with a valid SSN, confirm you have the physical Social Security card — the name must match the return exactly. For children with ITINs, accept that the ODC is the applicable credit and plan accordingly.

Step 3 — Confirm your own filing position. If you are married and your spouse has a valid work-authorized SSN, you are in a stronger position than a solo ITIN filer. Married filing jointly with one SSN-holding spouse opens the door to the full CTC for SSN-holding children.

Step 4 — Get organized before visiting a preparer. Bring Social Security cards and ITIN assignment letters for every person on the return. Bring proof of each child’s residency — school enrollment records, medical records, or a lease showing your household members. Bring your prior-year tax return. The more documentation you have in hand, the faster and more accurate the preparation will be.

Step 5 — File early. The IRS holds ACTC refunds until mid-February of the following year, regardless of when you file. But filing early means your return is processed first in line after that hold lifts. E-filing with direct deposit is the fastest combination. Paper returns take six to eight weeks even in favorable circumstances.
