US citizenship by birth
Children born in US (any US territory) automatically acquire US citizenship by birth (14th Amendment), regardless of parents' status. This applies even if parents are visa holders or undocumented.
Immediate tax implications
The child is a US person for life unless they renounce US citizenship as an adult.
Implications:
- Eligible for Social Security Number (SSN) immediately
- Subject to US worldwide income taxation from day one
- Future obligations: 1040, FBAR, Form 8938 as adults
When does the child need to file taxes?
The child needs to file if they have:
- Earned income > $14,600 (2024 standard deduction)
- Unearned income (interest, dividends, etc.) > $1,300 (2024)
- Combined income above kiddie tax thresholds
For Indian parents' children with US citizenship who live in India:
- If child has any India-source income (interest on bank account in their name, mutual fund), reportable to IRS
- FBAR applies if foreign accounts in child's name > $10K
Kiddie tax rules
Children under 19 (or under 24 if full-time student) with unearned income > $2,600 (2024) face kiddie tax — unearned income above that taxed at parents' marginal rate.
Avoidance strategies:
- Keep investment income in parent's name (parent uses own bracket)
- Use 529 plans for education savings
- For Indian-side, careful with FDs and dividends in child's name
OCI for child
If both parents are Indian citizens, child born in US can get OCI card as long as one parent is Indian citizen at time of birth.
If one parent is Indian citizen and other US citizen, child can still get OCI.
OCI lets child travel to India without visa, work in India, etc. Does NOT affect US citizenship.
Indian tax position for US-citizen child
Indian tax treatment based on day-count test in India. If child spends > 182 days in India, Indian resident for that year.
Income (interest on Indian account in child's name) taxed in India per residency rules.
US estate and gift planning
US-citizen child can be beneficiary of:
- US estate (within $13.61M lifetime exemption from US-person grandparent)
- Indian estate (Form 3520 if value > $100K from foreign-person grandparent)
Gifting to US-citizen child:
- From Indian grandparent (non-US person): Form 3520 if > $100K
- Carryover basis on transferred assets
Renouncing US citizenship as adult
If child grows up and decides to renounce (often to avoid worldwide income obligation):
- Must be at least 18
- Process at US consulate, ~$2,350 fee
- Form 8854 required
- §877A exit tax may apply if Covered Expatriate (rare for young adults but possible if wealthy)
Practical advice
- Get SSN immediately at birth (Form SS-5)
- Get OCI for child if Indian-citizen parent
- Be aware of kiddie tax when structuring child's Indian accounts
- Plan estate/gift documentation
- Discuss future US tax obligations with the child as they grow
Common mistakes
- Not getting SSN early (delays many future filings)
- Putting all Indian investment in child's name to "save" parents' tax (kiddie tax + FBAR for child + complexity)
- Missing US citizenship implications in Indian property documents (TDS rules different for US-person owners)
- Not informing child of future US tax obligations
