Child Tax Credit for Americans in Sweden: SSNs and Foreign Births

Which tax year is this guide about?

The 2027 filing season generally covers tax year 2026—income earned during 2026. The final 2026 Form 1040 instructions and Schedule 8812 should be checked before filing. Do not assume a credit amount from an earlier year automatically remains unchanged.

Who may be a qualifying child?

The Child Tax Credit has several tests. In general, the child must be under age 17 at the end of the tax year, meet the relationship and dependency requirements, have lived with you for more than half the year under the applicable rules, and satisfy the U.S. citizenship, national or resident-alien requirement. Income limits and other restrictions can also apply.

A child’s Swedish residence or Swedish citizenship alone does not determine eligibility. A child who lives in Sweden may still meet the residence test in the right circumstances, but the complete facts and the current IRS instructions control.

The SSN requirement

For the Child Tax Credit, the qualifying child generally must have an SSN that is valid for employment and issued on or before the due date of the return, including extensions. An Individual Taxpayer Identification Number (ITIN) for the child does not satisfy the Child Tax Credit’s SSN requirement.

For a joint return, the post-2025 rules generally require at least one spouse to have an SSN valid for employment; the other spouse must have an SSN or ITIN issued by the return due date, including extensions. For a single filer, the taxpayer’s own SSN rules also matter. Read the current Form 1040 instructions and Schedule 8812 rather than relying on this summary for a filing decision.

If your child was born outside the United States

First determine whether the child acquired U.S. citizenship at birth. Citizenship transmission to a child born abroad depends on the U.S. citizen parent’s circumstances and the applicable law; it is not automatic in every family situation.

• Review the U.S. Department of State’s rules for acquisition of citizenship by a child born abroad.
• If appropriate, apply for a Consular Report of Birth Abroad (CRBA) and/or U.S. passport through the U.S. Embassy or consular process.
• Understand that a CRBA documents U.S. citizenship at birth; it is not itself a Social Security number.
• Follow the Social Security Administration’s process for obtaining an SSN for a child abroad.
• Keep the child’s citizenship and SSN documents with your tax records.

A Swedish birth certificate alone does not establish that a child acquired U.S. citizenship. If the citizenship transmission rules are unclear, use the official State Department guidance or seek qualified advice before assuming the child qualifies for the credit.

How much is the credit for tax year 2026?

The 2025 tax-year instructions raised the maximum Child Tax Credit to $2,200 per qualifying child and provide for inflation adjustment after 2025. Because the exact tax-year 2026 amount should be confirmed in the final 2026 IRS instructions, this guide does not state a 2026 dollar limit as settled. Check the current Schedule 8812 and IRS Child Tax Credit page when preparing the return.

Do not confuse the maximum credit with the amount you can actually claim. Income, filing status, the qualifying-child tests, SSN rules and other limitations can change the result. The refundable Additional Child Tax Credit also has separate rules.

Americans abroad: FEIE, FTC and refundable credits

Choosing the Foreign Earned Income Exclusion (FEIE) rather than the Foreign Tax Credit (FTC) can affect other parts of a U.S. return. The interaction with the refundable Additional Child Tax Credit can be technical, particularly where foreign earned income is excluded. Do not choose FEIE solely because its headline exclusion looks large without comparing the overall return and credit consequences.

If you have multiple children, a non-U.S. spouse, a child with no SSN, a recent foreign birth, or prior-year returns that omitted a qualifying child, consider having a qualified U.S. international-tax professional review the facts.

Before claiming the credit

• Confirm the tax year and use that year’s Form 1040 instructions and Schedule 8812.
• Check the child’s age, relationship, dependency, residence and citizenship/residency tests.
• Confirm the child has the required SSN valid for employment, issued by the applicable deadline.
• For a child born abroad, confirm citizenship status and retain CRBA/passport and SSN records as applicable.
• Check the taxpayer and spouse identification-number rules for the filing status used.
• Compare the effects of FEIE and FTC before finalizing the return.
