Step 1: Secure the child's US citizenship documents
A child born in Switzerland to at least one US citizen parent generally acquires US citizenship at birth, provided the parent meets the physical-presence-in-the-US transmission test. You document that with a Consular Report of Birth Abroad (CRBA), the child's first US passport, and a Social Security number. Start the process at the US Embassy or consulate well before the child's 18th birthday—there is no need to wait, and the SSN is required to claim the child as a dependent on your US return.
- File the CRBA (Form DS-2029, now increasingly handled through the eCRBA system) with your evidence of physical presence.
- Apply for the child's first US passport using Form DS-11.
- After the CRBA and passport are issued, submit Form SS-5 for the Social Security number.
- Use that SSN on your next federal return to claim the child as a dependent.
Step 2: The US Child Tax Credit and the FEIE trap
For tax year 2025 returns, the Child Tax Credit is worth up to $2,200 per qualifying child under age 17 with a valid Social Security number. It has two parts: a non-refundable part that reduces your US tax to zero, and the Additional Child Tax Credit (ACTC), the refundable portion worth up to $1,700 per child. The ACTC requires at least $2,500 of earned income and is calculated as 15% of your earned income above $2,500, capped at $1,700 per child.
Here is the expat trap. If you use the Foreign Earned Income Exclusion (FEIE) on Form 2555, excluded income does not count as 'earned income' for the ACTC. A family that excludes all of its income can end up with $0 of the refundable credit. Using the Foreign Tax Credit on Form 1116 instead keeps earned income on the return and preserves the ACTC—this is one of the most consequential tax elections for new parents.
The FEIE trap in one sentence
If you eliminate all of your earned income with the Foreign Earned Income Exclusion, the refundable Additional Child Tax Credit can disappear. The Foreign Tax Credit usually keeps that income visible for ACTC purposes.

Maximum refundable Additional Child Tax Credit per qualifying child
Phase-out begins at $200,000 of modified adjusted gross income for single filers and $400,000 for married filing jointly, reducing the credit by $50 per $1,000 above the threshold. The credit is claimed on Schedule 8812. A child must have a valid Social Security number; an ITIN does not qualify for the CTC, though the $500 Credit for Other Dependents may still apply in some cases.
Step 3: Swiss family allowances (Kinderzulagen / Familienzulagen)
Swiss family allowances are a separate monthly payment from the Swiss system, paid out per child. The federal minimum is CHF 215 per child per month from birth to the 16th birthday, and CHF 268 per month for the education allowance (Ausbildungszulage) during post-compulsory education from around age 15/16 to the 25th birthday. Cantons often pay more: Zurich pays CHF 215 for children under 12 and CHF 268 from age 12, Bern CHF 250, Zug CHF 330, Geneva CHF 311, Vaud CHF 322 and Valais CHF 327. Eligibility generally requires paid work—employee or self-employed—earning at least CHF 7,560 per year (CHF 630 per month); non-employed low-income residents can apply through their canton's compensation office.

Federal minimum Swiss child allowance per child per month from birth
Swiss family allowances are taxable on the Swiss side and should be declared on your Swiss return. On the US side, many leading expat preparers treat Swiss family allowances as a welfare or family benefit that is not includible in US taxable income. That position is not a single bright-line IRS rule, so confirm it with a preparer rather than assume—it is a nuance that matters when the same money reaches a US account.
Swiss allowance and your US return
Swiss family allowances are taxable in Switzerland, but many expat tax preparers argue they are a welfare benefit outside US taxable income. Because this is an interpretive area, get the treatment confirmed as part of your preparation.
Step 4: The child's Swiss accounts and your FBAR
If you open a Swiss bank or savings account for the child and you have signature authority, that account counts toward your own FBAR reporting once your combined foreign accounts exceed $10,000 at any point during the year—even if the money is 'for the child.' Many parents don't realize this overlap until it is time to file. The mechanics are straightforward, but the aggregation rules catch people; see FBAR Filing for Americans in Switzerland: 2026 Deadlines and Rules for the details.
Putting the pieces together
The birth itself triggers several parallel tracks: citizenship documentation at the embassy, a tax election on your US return, a Swiss family allowance application, and careful FBAR aggregation. None of these require you to become a tax expert. Get the CRBA and SSN process moving early, model the FEIE-versus-FTC decision with your actual numbers, apply for the Swiss allowance through your employer or canton, and watch account balances.
If you are already thinking about education funding, the next question is usually whether a 529 still makes sense under Swiss tax rules—529 College Savings Plans for US Expats in Switzerland: Do They Still Make Sense? covers that decision separately.
Every family's mix of Swiss employer, US filing status and future plans is different. Use this as a framework, then have the actual implementation checked by a cross-border tax specialist.
