Children and dependents tax credit

Yes — US expats can claim the Child Tax Credit for each qualifying child under 17, worth up to $2,200 per child for the 2025 tax year, under the same rules that apply to taxpayers living in the US. The child generally needs a valid Social Security Number, and the credit phases out once your income passes $200,000 (single or head of household) or $400,000 (married filing jointly). Living abroad doesn't disqualify you from the credit itself, but it does affect how much of it you can actually collect as a refund, depending on which foreign income relief method you use.

Yes — where a child physically lives doesn't disqualify them as your dependent, but the child themselves must be a US citizen, US national, US resident alien, or a resident of Canada or Mexico to qualify. Alongside that citizenship/residency test, the usual relationship, age, and support tests still apply. This comes up often for expat families with children born abroad or with a non-US-citizen spouse; if you're navigating a custody arrangement on top of that, Form 8332 governs which parent gets to claim the dependency-related benefits.

Yes, if that foreign income crosses the same filing thresholds that apply to any dependent — for 2025, more than $15,750 in earned income, more than $1,350 in unearned income, or $400 or more in net self-employment earnings. Foreign-source income counts exactly the same as US-source income for this test; there's no exemption just because the income was earned or paid abroad. If your child's foreign earnings are the issue, it's worth checking whether they qualify for their own foreign income relief, since the filing requirement and the tax owed are separate questions — see how minors' filing obligations work in more detail.

Yes, but which foreign-income relief method you use changes how much of the credit you can actually collect. The Child Tax Credit itself isn't restricted to US residents, but $1,700 of the $2,200 per-child amount is refundable through the Additional Child Tax Credit — and that refundable portion is only available if you have qualifying earned income after using the Foreign Tax Credit rather than the Foreign Earned Income Exclusion. Many expat parents accidentally give up the refundable portion simply by defaulting to Form 2555 without comparing the two options first.

The Additional Child Tax Credit (ACTC) is the refundable portion of the Child Tax Credit — up to $1,700 per child for 2025 — that you can receive even if you owe little or no US tax. Expats can claim it, but only if they have qualifying earned income to calculate it against; claiming the Foreign Earned Income Exclusion on Form 2555 disqualifies the refundable ACTC entirely, even if every other requirement is met, because it zeroes out the earned income the refund is calculated from. Claiming the Foreign Tax Credit instead usually preserves access to this refundable amount.

Not necessarily to be claimed as a dependent, but yes to unlock the full Child Tax Credit — a child without a Social Security Number can still be claimed with an ITIN or ATIN, but only qualifies you for the $500 Credit for Other Dependents instead of the $2,200 Child Tax Credit. The SSN generally needs to be issued before the filing deadline for the return it's being claimed on; a number obtained later can't retroactively unlock the larger credit for that year. For many expat families with a child born abroad, getting the SSN application filed early avoids losing a full year of the credit.

Using the Foreign Earned Income Exclusion doesn't take away the nonrefundable part of the Child Tax Credit, but it blocks the $1,700 refundable Additional Child Tax Credit completely. The nonrefundable portion can only offset actual US tax owed — and for many expats, the FEIE already excludes enough income that little or no US tax is left to offset, making that portion effectively worthless too. This is one of the most common FEIE-related traps for families with kids, and it's worth running the numbers both ways (FEIE vs. Foreign Tax Credit) before defaulting to the exclusion.

Yes, but only if the foreign school is an "eligible educational institution" — meaning it participates in the US Department of Education's federal student aid program and has a Federal School Code. If it qualifies, tuition and required fees can count toward the American Opportunity Tax Credit or the Lifetime Learning Credit just like a US school would. One added wrinkle for expat families: if you use the Foreign Earned Income Exclusion, the excluded amount gets added back when calculating your MAGI for these education credits, which can push you over the income phase-out even though your taxable income looks low.

There's no age cutoff at all — the filing requirement is based on income, not age, so even a young child can owe their own return the moment their income crosses the threshold. For 2025, that means more than $15,750 in earned income, more than $1,350 in unearned income (interest, dividends, capital gains), or $400 or more in net self-employment earnings. Parents can sometimes avoid a separate return for a child's investment income by electing to report it directly on their own return using Form 8814 instead — worth checking before assuming a return is required. See how minors' filing obligations apply in more detail.

Not directly — studying abroad has no bearing on the Child Tax Credit itself, since that credit is tied to the child's age (under 17) and dependency status, not their school or its location. Where this gets confused: once a dependent turns 17 or is in college, they typically age out of the Child Tax Credit and shift to the $500 Credit for Other Dependents, and separately, their tuition may qualify you for an education credit — but that's a different benefit governed by different rules, including whether the Foreign Earned Income Exclusion gets added back for MAGI purposes.

Yes — your child's physical location doesn't disqualify you from the Child Tax Credit, the Credit for Other Dependents, or education credits, as long as the child otherwise meets the dependency, citizenship or residency, and support tests. What actually determines eligibility is the child's citizenship/residency status (US citizen, national, resident alien, or resident of Canada or Mexico) and whether you provide more than half their support — not which country they happen to be living or going to school in.

Yes — your own residency abroad doesn't affect your eligibility for the Child Tax Credit, since US citizens and green card holders are taxed (and eligible for most credits) on worldwide income regardless of where they live. Your foreign-currency income is converted to US dollars and counted the same way domestic income would be for the $200,000/$400,000 phase-out thresholds. The part that actually changes when you live abroad isn't eligibility — it's whether you can access the refundable Additional Child Tax Credit, which depends on choosing the Foreign Tax Credit over the Foreign Earned Income Exclusion.
