FATCA Compliance for Caribbean CBI Citizens: What US Passport Holders Must Do

FATCA compliance for Caribbean CBI US passport holders is a non-negotiable obligation that carries penalties of up to $50,000 per year for non-compliance. If you hold US citizenship or a green card and have acquired a second passport through a Caribbean citizenship by investment programme, you must understand how the Foreign Account Tax Compliance Act affects your financial reporting — both in the United States and in your new country of citizenship. Processing a fully compliant CBI application typically takes 3–7 months, but the tax obligations that follow last a lifetime.

What Is FATCA and Why Does It Matter for CBI Citizens?

The Foreign Account Tax Compliance Act (FATCA) is a United States federal law enacted in 2010 as part of the HIRE Act. It requires US citizens, US residents, and US green card holders to report foreign financial accounts and assets to the Internal Revenue Service (IRS) when those assets exceed certain thresholds. FATCA also compels foreign financial institutions (FFIs) worldwide to identify and report accounts held by US persons or face a 30% withholding tax on US-source payments.

For high-net-worth individuals who have obtained Caribbean citizenship through investment — whether via Antigua & Barbuda, St. Kitts & Nevis, Dominica, Grenada, or St. Lucia — FATCA compliance is critically important for several reasons:

US Tax Obligations Follow the Passport, Not the Address

Unlike almost every other country in the world (with the notable exception of Eritrea), the United States taxes its citizens on their worldwide income regardless of where they live. Acquiring a Caribbean passport does not change this fundamental obligation. Even if you relocate to Antigua, open bank accounts in St. Kitts, and conduct all your business from the Caribbean, the IRS considers you a US taxpayer until you formally renounce your US citizenship — a process that itself triggers significant tax consequences under Section 877A of the Internal Revenue Code (the "exit tax").

Caribbean Banks Are Obligated to Report

Every Caribbean CBI jurisdiction has entered into an Intergovernmental Agreement (IGA) with the United States. These bilateral agreements require local financial institutions to identify accounts held by US persons and transmit that information to the IRS, typically through the jurisdiction's local tax authority. This means that any bank account you open using your new Caribbean passport will still be flagged if the bank's due diligence process identifies you as a US person — which it will, because OECD Common Reporting Standard (CRS) protocols and Know Your Customer (KYC) requirements mandate disclosure of all citizenships and tax residencies.

FATCA Reporting Thresholds for US Persons with Caribbean CBI Citizenship

Understanding the precise thresholds is essential to maintaining compliance. FATCA reporting obligations are triggered when your specified foreign financial assets exceed certain values, and these thresholds vary depending on your filing status and whether you reside in the United States or abroad.

FATCA Reporting Thresholds (Form 8938) for US Persons

Filing Status	Residing in the US — Year-End Threshold	Residing in the US — At Any Time During Year	Residing Abroad — Year-End Threshold	Residing Abroad — At Any Time During Year
Single / Married Filing Separately	$50,000	$75,000	$200,000	$300,000
Married Filing Jointly	$100,000	$150,000	$400,000	$600,000

For UHNW individuals investing a minimum of $130,000 to $250,000 in a Caribbean CBI programme, plus maintaining foreign bank accounts, investment portfolios, and potentially real estate holdings, these thresholds are almost always exceeded. This means Form 8938 (Statement of Specified Foreign Financial Assets) must be filed alongside your annual US tax return.

FATCA vs. FBAR: Two Separate Obligations

Many CBI citizens confuse FATCA reporting (Form 8938) with FBAR reporting (FinCEN Form 114). These are separate requirements with different thresholds, filing deadlines, and penalties:

• FATCA (Form 8938): Filed with your annual tax return to the IRS. Covers specified foreign financial assets including bank accounts, securities, financial instruments, and interests in foreign entities. Thresholds vary as shown above.
• FBAR (FinCEN Form 114): Filed electronically with the Financial Crimes Enforcement Network (FinCEN). Required when the aggregate value of all foreign financial accounts exceeds $10,000 at any point during the calendar year. Due 15 April (with automatic extension to 15 October).

If you hold accounts in both your Caribbean CBI jurisdiction and other countries, the balances are aggregated for FBAR purposes. A US citizen with a Grenadian passport who maintains accounts in Grenada, Switzerland, and Dubai could easily trigger both FATCA and FBAR thresholds simultaneously.

Caribbean CBI Jurisdictions and Their FATCA Agreements with the United States

Each of the five Caribbean CBI nations has formalised its FATCA cooperation with the United States. Understanding the specific type of IGA your new country has signed helps you anticipate how your financial information flows to the IRS.

FATCA Intergovernmental Agreement Status of Caribbean CBI Jurisdictions

Caribbean CBI Jurisdiction	IGA Type	CBI Minimum Investment	Visa-Free Destinations	Processing Time
Antigua & Barbuda	Model 1 IGA	$230,000	144	3–6 months
St. Kitts & Nevis	Model 1 IGA	$250,000	148	4–6 months
Dominica	Model 1 IGA	$200,000	136	4–6 months
Grenada	Model 1 IGA	$235,000	140	5–7 months
St. Lucia	Model 1 IGA	$240,000	140	4–10 months

Under a Model 1 IGA, foreign financial institutions report US account holder information to their local government authority, which then transmits the data to the IRS. This means banks in all five Caribbean CBI jurisdictions are legally compelled to identify and report your accounts. Attempting to open accounts using only your new Caribbean passport without disclosing US citizenship is not only futile — it constitutes a federal offence.

The ECCIRA Effect: How the New Caribbean CBI Regulator Impacts FATCA Compliance

The establishment of the Eastern Caribbean CBI Regulatory Authority (ECCIRA) in December 2025, with full operations commencing in April 2026, marks a transformative moment for Caribbean investment migration. Headquartered in Grenada, ECCIRA will harmonise CBI standards across participating Caribbean nations, and its mandate includes enhanced due diligence protocols that have direct implications for FATCA compliance.

Stricter Due Diligence Benefits Compliant Applicants

ECCIRA's unified framework is expected to include standardised background checks that verify applicants' tax compliance status in their home jurisdictions. For US passport holders, this means demonstrating FATCA compliance will likely become an implicit — if not explicit — component of the CBI application process. Applicants who can demonstrate a clean tax record and proper FATCA filing history will find their applications processed more smoothly and with greater confidence from CBI units.

Information Sharing and Transparency

ECCIRA's regulatory oversight will also facilitate greater information sharing between Caribbean jurisdictions and international tax authorities. This enhanced transparency reinforces the importance of proactive FATCA compliance: the days of regulatory gaps between Caribbean nations are numbered, and the cost of non-compliance will only increase.

Common FATCA Mistakes Made by US Citizens with Caribbean CBI Passports

In our experience processing over 250 Caribbean CBI cases at Mirabello Consultancy, we have observed several recurring FATCA compliance errors among US passport holders. Avoiding these mistakes can save you significant penalties and legal costs.

Mistake 1: Assuming a Second Passport Reduces US Tax Obligations

Acquiring citizenship in Dominica or any other Caribbean nation does not reduce, defer, or eliminate your US tax obligations. Your worldwide income remains reportable to the IRS. A second passport provides mobility, security, and lifestyle benefits — it is not a tax planning instrument in and of itself.

Mistake 2: Failing to Disclose the New Citizenship to Financial Institutions

When you acquire Caribbean citizenship, your existing banks and financial institutions — in the US, the Caribbean, and worldwide — must be informed if they request updated KYC information. Deliberately concealing a new citizenship or using it to open accounts without disclosing US person status violates both FATCA and anti-money laundering regulations.

Mistake 3: Not Filing Form 8938 Alongside Annual Tax Returns

Many US citizens with Caribbean CBI passports file their standard tax returns but neglect Form 8938 — the FATCA-specific disclosure. If your specified foreign financial assets exceed the thresholds outlined above, this form is mandatory. Failure to file carries a penalty of $10,000 per violation, rising to $50,000 for continued non-compliance after IRS notification.

Mistake 4: Confusing Tax Residency with Tax Citizenship

Some CBI clients believe that by establishing tax residency in a zero-income-tax Caribbean jurisdiction, they can eliminate US tax liability. This is incorrect. Tax residency and tax citizenship are distinct concepts. As a US citizen, you remain subject to US taxation regardless of where you are tax-resident. Dual tax residency may, however, entitle you to certain treaty benefits or foreign tax credits — but only if properly structured with qualified tax counsel.

Mistake 5: Ignoring PFIC Rules on Foreign Investment Funds

US citizens who invest in foreign mutual funds or pooled investment vehicles through their Caribbean accounts may trigger Passive Foreign Investment Company (PFIC) rules, which impose punitive tax rates. This is particularly relevant for CBI citizens who invest in Caribbean real estate funds or development projects as part of their citizenship application.

Step-by-Step FATCA Compliance Checklist for Caribbean CBI Citizens

Whether you have already obtained your Caribbean passport or are in the application phase, the following checklist will help you maintain full FATCA compliance:

Before Your CBI Application

1. Engage a US cross-border tax adviser experienced in both CBI structuring and FATCA/FBAR requirements. Ideally, this adviser should work in coordination with your CBI consultant.
2. Compile a complete inventory of all foreign financial accounts and assets, including bank accounts, brokerage accounts, insurance policies with cash value, pension plans, and interests in foreign entities.
3. Review historical FBAR and Form 8938 filings for accuracy and completeness. If prior filings were missed, consider the IRS Streamlined Filing Compliance Procedures to remedy the situation with reduced penalties.
4. Evaluate your CBI investment structure with tax implications in mind. A donation to a national fund has different FATCA reporting implications than a real estate investment that generates rental income in a foreign jurisdiction.

During and After Your CBI Application

1. Disclose your US citizenship on your CBI application. Reputable programmes such as those administered by Antigua & Barbuda's CIP Unit and St. Kitts & Nevis's CIU require full disclosure of all existing citizenships.
2. Inform all financial institutions of your new citizenship when updating KYC documentation. Do not attempt to compartmentalise identities across jurisdictions.
3. File Form 8938 with your US tax return each year if thresholds are met. Report all specified foreign financial assets, including accounts in your new CBI country.
4. File FinCEN Form 114 (FBAR) by the annual deadline if aggregate foreign account balances exceed $10,000 at any point during the year.
5. Report foreign rental income if your CBI investment involves real estate that generates income. This income must be declared on your US return, though foreign tax credits may apply.
6. Maintain meticulous records of all CBI-related transactions, including government fees, agent fees, due diligence costs, and investment documentation. These records support your tax filings and may be relevant in the event of an IRS audit.

Grenada's E-2 Treaty: Unique FATCA Considerations for US Investors

Grenada occupies a unique position among Caribbean CBI programmes because it is the only one with an E-2 Investor Visa treaty with the United States. This treaty allows Grenadian citizens to invest in and manage a US-based business whilst residing in the United States on an E-2 visa.

For US citizens who already hold a US passport, the E-2 treaty is less directly relevant — you already have the right to work and invest in the US. However, if you are considering Grenadian citizenship as part of a broader family strategy (for example, for a non-US spouse or family members), the FATCA implications multiply:

• Joint accounts between a US citizen and a non-US Grenadian citizen spouse may still be reportable if the US citizen has signatory authority or a financial interest in the account.
• Business structures established in Grenada by family members may constitute Controlled Foreign Corporations (CFCs) or Passive Foreign Investment Companies (PFICs) from a US tax perspective, depending on ownership percentages.
• Gift and inheritance tax implications arise when assets flow between US and non-US family members with different citizenships.

These complexities underscore the importance of integrated tax and immigration planning from the outset. At Mirabello Consultancy, we coordinate with specialist tax advisers to ensure that your CBI strategy aligns with your broader wealth structuring objectives. For those exploring alternative residency-based options, our golden visa hub provides a complementary overview.

Penalties for FATCA Non-Compliance: What US-Caribbean Dual Citizens Risk

The consequences of FATCA non-compliance are severe and escalating. US citizens with Caribbean CBI passports who fail to meet their reporting obligations face the following penalties:

• Form 8938 non-filing: $10,000 penalty per violation. If non-compliance continues for more than 90 days after IRS notification, an additional $10,000 penalty accrues for each 30-day period (up to $50,000).
• FBAR non-filing (non-wilful): Up to $10,000 per account per year.
• FBAR non-filing (wilful): The greater of $100,000 or 50% of the account balance per violation. Criminal penalties may also apply, including up to five years' imprisonment.
• Accuracy-related penalties: A 40% penalty on underpayments attributable to undisclosed foreign financial assets.
• Criminal prosecution: In cases of wilful tax evasion or fraudulent concealment of foreign accounts, the US Department of Justice may pursue criminal charges carrying sentences of up to five years per count.

These penalties apply regardless of whether the US citizen's Caribbean CBI passport was obtained through St. Kitts & Nevis (the world's oldest CBI programme, established in 1984), St. Lucia, or any other jurisdiction. The IRS does not distinguish between citizenships acquired by birth, naturalisation, or investment.

Frequently Asked Questions

Does Acquiring Caribbean CBI Citizenship Eliminate My US Tax Obligations?

No. The United States taxes its citizens on worldwide income regardless of additional citizenships, residencies, or where they physically reside. Acquiring a passport from Antigua & Barbuda, St. Kitts & Nevis, Dominica, Grenada, or St. Lucia does not change your US tax status. Only formal renunciation of US citizenship — which triggers an exit tax assessment under IRC Section 877A — ends the obligation, and even then, prior-year liabilities must be fully resolved.

What Is the FATCA Filing Threshold for US Citizens Living in the Caribbean?

If you reside outside the United States (including in a Caribbean CBI jurisdiction), the FATCA reporting threshold for Form 8938 is $200,000 in specified foreign financial assets at year-end, or $300,000 at any point during the year, for single filers. Married couples filing jointly face thresholds of $400,000 and $600,000 respectively. These higher thresholds for overseas residents recognise that foreign accounts are a necessity, not an anomaly, for expatriates.

Will My Caribbean Bank Automatically Report My Accounts to the IRS?

Yes. All five Caribbean CBI jurisdictions have signed Model 1 Intergovernmental Agreements with the United States. Under these agreements, local financial institutions identify US person accounts and report the information to their national tax authority, which then transmits it to the IRS. Banks use KYC procedures to identify US indicia — including US place of birth, US address, US telephone number, and self-certification of US citizenship — making it virtually impossible to avoid detection.

Can I Use My Caribbean Passport to Open a Bank Account Without Disclosing US Citizenship?

Absolutely not. Deliberately concealing US citizenship from a foreign financial institution to avoid FATCA reporting constitutes a criminal offence under US law. Banks that comply with FATCA regulations (as all Caribbean CBI jurisdiction banks must) ask customers to self-certify their tax residencies and citizenships. Providing false information on these forms exposes you to criminal prosecution, account closure, and blacklisting by compliant financial institutions worldwide.

How Does the CBI Investment Itself Get Reported Under FATCA?

The reporting depends on the type of CBI investment. A donation to a government fund (such as Dominica's Economic Diversification Fund) is a one-time expenditure that does not create an ongoing foreign financial asset requiring annual FATCA reporting. However, a real estate investment creates a foreign asset that may generate rental income — and whilst real estate itself is not a "specified foreign financial asset" under Form 8938, any foreign bank account holding rental proceeds or investment returns is reportable. Additionally, investments in approved development projects structured as shares or partnership interests may qualify as specified foreign financial assets.

What Happens If I Have Not Filed FATCA Forms in Previous Years?

If you have failed to file Form 8938 or FBAR in prior years, the IRS offers remediation pathways. The Streamlined Filing Compliance Procedures allow taxpayers who can certify that their non-compliance was non-wilful to file amended returns for the prior three years and delinquent FBARs for the prior six years, typically with a reduced penalty of 5% of the highest aggregate balance (or no penalty for those residing abroad). The Voluntary Disclosure Practice is available for those whose non-compliance may be considered wilful. We strongly recommend engaging a qualified US cross-border tax attorney before pursuing either pathway.

Does Vanuatu's CBI Programme Have the Same FATCA Implications?

Vanuatu, whilst offering the fastest CBI processing at approximately 45–60 days with a minimum investment of $130,000, has a different FATCA posture than the Caribbean jurisdictions. Vanuatu has entered into a FATCA agreement with the United States, and its financial institutions are expected to comply with reporting requirements. However, Vanuatu's passport offers only 91 visa-free destinations with no Schengen access, which may affect its suitability for some US investors. For details, visit our Vanuatu programme page. The FATCA obligations for a US citizen holding a Vanuatu passport are identical to those holding a Caribbean passport — the filing requirements follow the person, not the passport.
