FATCA and Investment Migration: What US Persons Must Know Before Planning Second Citizenship
The Foreign Account Tax Compliance Act (FATCA), enacted in 2010 and progressively implemented from 2014 onwards, fundamentally changed the relationship between US persons and the global financial system. For HNW US persons pursuing second citizenship, residency abroad, or both, FATCA creates obligations and complications that must be understood and managed before any investment migration planning begins.
This guide explains FATCA's core mechanics, its interaction with the FBAR reporting regime, the practical consequences for banking access abroad, and the planning considerations relevant to US citizens and long-term residents considering investment migration.
US tax law and FATCA regulations are complex and change frequently. Nothing in this guide constitutes US tax advice. US persons engaged in investment migration planning must engage US-qualified tax counsel — specifically a practitioner with experience in international tax and expatriate matters — before taking any action.
What FATCA Does
FATCA requires foreign financial institutions (FFIs) — banks, investment firms, insurance companies, pension managers, and others — to identify accounts held by US persons and report information about those accounts to the US Internal Revenue Service (IRS), either directly or through their government under an Intergovernmental Agreement (IGA).
In exchange, FFIs that comply are exempt from a 30% withholding tax on certain US-source payments. Non-compliant FFIs face that withholding — creating a powerful financial incentive for global compliance.
The result is that more than 110 countries and territories have signed IGAs with the United States, and more than 500,000 financial institutions worldwide have registered with the IRS as FATCA-compliant. Information about US persons' offshore accounts flows routinely to the IRS.
Who Is a "US Person" for FATCA Purposes?
The FATCA definition of US person is broad:
- US citizens, wherever resident or domiciled
- US lawful permanent residents (Green Card holders)
- Individuals who meet the US Substantial Presence Test (spending sufficient days in the US over a rolling three-year period)
- Certain trusts and estates with US connections
Critically, this definition follows US tax law rather than residency. A US citizen who has lived outside the United States for 30 years, holds no US property, and maintains no other US connections remains a US person for FATCA purposes.
The FBAR Trap
Separate from FATCA, the Foreign Bank Account Report (FBAR) — filed on FinCEN Form 114 — requires US persons to report foreign financial accounts with an aggregate maximum value exceeding $10,000 at any point during the calendar year. FBAR reporting is extraordinarily broad: it captures bank accounts, investment accounts, insurance policies with cash value, and beneficial interests in foreign entities holding such accounts.
FBAR penalties for wilful violations are severe — up to the greater of $100,000 or 50% of the account balance per violation. Non-wilful penalties are up to $10,000 per violation. The US government has pursued FBAR enforcement aggressively against US persons who held undisclosed offshore accounts.
For HNW individuals, the FBAR regime means that offshore accounts — whether in Switzerland, Singapore, UAE, or anywhere else — are not private from the US government. Any investment migration strategy must assume full IRS visibility of offshore financial holdings.
Non-US Spouses: The Reporting Complication
One of the most practically challenging FATCA interactions involves non-US spouses of US persons. Where a non-US citizen is married to a US person:
Joint accounts: Any jointly held financial account is reportable under FATCA and FBAR. The non-US spouse's financial information in a joint account becomes visible to the IRS.
Separately held accounts: A non-US spouse's accounts that are held solely in their name (with no US person as an account holder or beneficial owner) are generally not reportable by the US person. However, FFIs may still apply enhanced due diligence and some institutions restrict services to spouses of US persons even where no technical reporting obligation exists.
Gift tax implications: Gifts from a US person to a non-US citizen spouse are treated differently from gifts to a US citizen spouse. The annual exclusion for gifts to a non-US citizen spouse is limited to an inflation-adjusted amount ($194,000 in 2026), compared to unlimited marital gift exclusions for US citizen spouses. This affects how assets can be transferred within a married couple for investment migration purposes.
Community property states: For couples with any US connection, community property rules in certain US states can further complicate the attribution of foreign accounts between spouses.
Foreign Financial Institution Account Closures
A less discussed but practically significant consequence of FATCA is the phenomenon of FFIs declining to open accounts — or closing existing accounts — for US persons.
The compliance burden of maintaining FATCA-compliant accounts for US persons is material. For smaller banks in particular, the administrative cost of identifying, reporting, and managing US person accounts can outweigh the commercial benefit. The result has been a pattern of account closures and restrictions:
- Swiss private banks have closed accounts of non-ultra-HNW US persons in significant numbers since 2014
- Several European retail banks have declined new US person clients
- Some Asian banks have restricted investment products available to US persons
For HNW US persons pursuing investment migration, this creates practical challenges: establishing banking relationships in new residency jurisdictions can be more difficult than for non-US persons. The UAE, Singapore, and Switzerland — all popular destinations for HNW individuals — have seen these dynamics at varying levels of intensity.
Planning should include early engagement with banking partners in target jurisdictions to confirm their US person policy before residency arrangements are finalised.
FATCA-Compliant Banking in Popular Expatriate Destinations
UAE: The UAE has an IGA with the United States. Major UAE banks — Emirates NBD, First Abu Dhabi Bank, Abu Dhabi Commercial Bank — are FATCA-registered and can maintain accounts for US persons. The practical experience varies: private banking relationships are generally accessible for HNW US persons; retail banking is more variable.
Singapore: Singapore has an IGA. Major banks (DBS, UOB, OCBC, and international private banks with Singapore operations) maintain US person accounts, subject to enhanced due diligence. Private banking in Singapore remains accessible for HNW US persons, though institutional costs are higher than for non-US clients.
Switzerland: Switzerland's IGA with the US took effect in 2014 after the US-Swiss banking crisis. Swiss private banks maintain FATCA compliance and do serve US person clients, but typically only at the private banking level ($1 million or more in assets under management). Retail banking for US persons in Switzerland is difficult.
Cayman Islands, BVI: Both have IGAs and are routinely used for HNW investment structures. The key is that all US person beneficial ownership must be disclosed.
Caribbean CBI destinations: The Caribbean jurisdictions operating CBI programmes (St Kitts, Dominica, Grenada, Antigua, St Lucia) all have IGAs in effect. Local banking in these jurisdictions is accessible but limited in sophistication; most HNW clients who acquire Caribbean citizenship maintain banking relationships elsewhere.
Key Planning Points for US Persons
Do not assume offshore means invisible: FATCA and FBAR ensure that foreign accounts are visible to the IRS in all practical terms. Any planning based on the premise of hiding assets from the US government creates criminal exposure, not protection.
Exit tax: US citizens and long-term residents who renounce citizenship or relinquish their Green Card may be subject to the US exit tax (mark-to-market deemed disposition of worldwide assets) if they meet the net worth threshold ($2 million or more) or fail the five-year tax compliance test. Exit tax planning is a sophisticated discipline and should be addressed before, not after, any renunciation.
Foreign trust reporting: US persons with interests in foreign trusts — whether as settlors, beneficiaries, or protectors — face extensive Form 3520 reporting requirements. This interacts heavily with trust structures used in CBI jurisdictions.
Treaty overrides: The US has tax treaties with many countries, but the "Savings Clause" in most US treaties preserves the US right to tax its own citizens regardless of residence. Most treaty benefits that reduce withholding or tax residency do not apply to reduce US taxation of US persons.
The only complete solution: Renunciation of US citizenship is the only way to fully exit the US worldwide tax system. This is a major decision with permanent consequences and should be considered only after comprehensive planning.
