Open a bank account in Grenada and somewhere in the pile of forms you will find questions about your tax residence, your tax identification numbers and, where relevant, your status as a US person. Those questions exist because Grenada participates in two international systems of automatic tax information exchange: the United States' Foreign Account Tax Compliance Act (FATCA) and the OECD's Common Reporting Standard (CRS).
Many newcomers assume that a bank account in a small Caribbean country is invisible to tax authorities at home. That has not been true for years. This explainer covers what the two regimes are, which account holders are affected, what information is sent abroad, and how to complete the paperwork accurately. It is general information: for your own position, confirm with a licensed tax adviser in each country where you may be tax resident.
FATCA: the US system
FATCA is a US law requiring foreign financial institutions to identify accounts held by US persons, meaning US citizens, green-card holders and US tax residents, and to report information about them to the US Internal Revenue Service. Rather than have each bank report directly, many countries signed intergovernmental agreements with the United States. Under Grenada's agreement, Grenadian financial institutions report to the Inland Revenue Division, which passes the information to the IRS.
For a US citizen living in Grenada, this means the bank will ask for a Form W-9 with a US taxpayer identification number. US citizens remain taxable in the United States on worldwide income wherever they live, and they have separate US filing obligations for foreign accounts, such as the annual report of foreign bank accounts above certain thresholds. FATCA does not create those obligations; it makes it likely the IRS already knows about the account. US persons living in Grenada should work with an adviser who understands both US expatriate tax and Grenadian rules.
CRS: the international system
The Common Reporting Standard, developed by the OECD, applies the same idea among more than a hundred participating jurisdictions. Banks identify account holders who are tax resident in another participating country and report their account information to the local tax authority, which exchanges it annually with the authority of the holder's country of residence. Grenada committed to the CRS and has exchanged information under it for several years, again through the Inland Revenue Division.
CRS is based on tax residence, not citizenship. A British citizen who is tax resident only in Grenada is generally not reported to the UK, while one who remains UK tax resident is. Someone with several tax residences may be reported to each. The United States is not part of CRS, which is why FATCA operates as a separate track. Because the system depends on self-certification, the forms you sign at account opening, and keep updated, decide where your information goes.
What information is reported
The details exchanged under FATCA and CRS are broadly similar, and they cover identity and money rather than individual transactions. A bank does not send a list of your purchases or transfers; it sends a snapshot of who holds the account and what it held or earned over the year. For each reportable account, the bank typically provides:
- Name, address and date of birth of the account holder, and for entities, the controlling persons.
- Tax identification numbers in the relevant country or countries of residence.
- Account number and the name of the reporting financial institution.
- The account balance or value at the end of the reporting period, or on closure.
- Gross interest, dividends and other income credited to the account, and for some accounts, gross proceeds from sales of financial assets.
- For companies and trusts, information about the individuals who control them where the entity is passive, such as a holding company with mainly investment income.
Who handles the data and how it travels
Banks do not send your information straight to a foreign tax office. They file reports with Grenada's Inland Revenue Division, which acts as the competent authority and exchanges the data with partner authorities under the agreements Grenada has signed. Exchanges are annual and relate to the previous calendar year, so information about an account opened in March typically travels the following year.
Partner authorities are bound by confidentiality rules in the agreements and may use the data only for tax purposes. Countries that fail to meet the OECD's data-protection standards can be excluded from receiving information. For account holders, the practical consequence is timing: a tax authority abroad may write to you about a Grenadian account a year or more after it was opened, and it helps to have the bank statements and your self-certification at hand when that happens. If your tax adviser at home asks for the account details, provide them; consistency between your return and the exchanged data is the point of the system.
Completing the self-certification correctly
Mistakes on these forms create problems later. A sensible approach is:
- Work out your tax residence before you sign, using the rules of each country concerned; residence can depend on days spent, home availability and other ties, not just where you live most of the time.
- List every country where you are tax resident, with a tax identification number for each. If a country does not issue numbers, the form usually allows an explanation.
- US citizens and green-card holders complete a W-9 regardless of where they live.
- For company accounts, identify whether the entity is active or passive under the definitions on the form, and list controlling persons where required; ask your accountant if unsure.
- Keep a copy of what you signed and diarise a review whenever your circumstances change.
- Tell the bank within the time it requests if your residence changes, for example after moving to Grenada full-time or leaving it.
Investor citizens and residence schemes
Holders of Grenadian citizenship by investment should be particularly careful. The OECD has identified some citizenship and residence by investment schemes as potentially usable to misrepresent tax residence under CRS, and banks around the world have been told to ask extra questions when a client presents such documents. A Grenadian passport does not make someone tax resident in Grenada. Tax residence depends on the facts, mainly presence and ties, under Grenada's income tax rules and those of other countries.
In practice, a bank may ask an investor citizen where they actually live, how many days they spend in each country and whether they file tax returns anywhere. Answering honestly and consistently is essential. Claiming Grenadian residence without the facts to support it, to avoid reporting to another country, can expose the account holder to penalties and the account to closure. An adviser who understands both Grenada's rules and the other jurisdictions involved should review your position before you complete the forms.
Common misunderstandings
Several myths circulate among newcomers. One is that only large balances are reported. Thresholds exist for some pre-existing accounts, but new individual accounts are generally reviewed regardless of size, and once an account is reportable, its balance is reported whatever it is. Another is that credit unions are exempt. Many financial institutions beyond commercial banks, including some credit unions, insurers with investment products and investment entities, fall within the rules, though exceptions apply to some low-risk institutions.
A third myth is that reporting equals tax. FATCA and CRS share information; they do not impose tax. Whether you owe anything depends on the law of each country of residence. Equally, being reported does not mean you are in trouble: most reports simply confirm what taxpayers already declare. The aim should be consistency between what your bank reports and what you file. For anything beyond a simple situation, confirm with a licensed tax professional rather than relying on general guidance. Advice taken before the account is opened is cheaper than correcting years of inconsistent filings afterwards.
Frequently asked questions
Does a Grenadian bank report accounts to the IRS?
Indirectly, yes. Under the FATCA agreement, Grenadian financial institutions report information on accounts held by US persons to the Inland Revenue Division, which forwards it to the IRS. US citizens and green-card holders should expect to complete a Form W-9.
Is someone who lives in Grenada full-time reported under CRS?
If you are tax resident only in Grenada, CRS reporting to another country generally does not arise. If you remain tax resident elsewhere, your information may be reported there. Your self-certification determines this, so complete it carefully and keep it updated.
Does citizenship by investment change tax residence?
No. Citizenship and tax residence are different things. Tax residence depends on presence and ties under each country's rules. Banks may ask investor citizens additional questions about where they actually live, so answer accurately and take professional advice.
Are credit union accounts covered by CRS and FATCA?
Some credit unions and other non-bank institutions fall within the rules, while certain low-risk institutions may be exempt. Ask your credit union whether it reports and complete any self-certification it requests. Do not assume an account is outside the regime.
What happens if the self-certification form is refused or left blank?
Banks generally cannot open an account without a valid self-certification, and existing accounts may be restricted or closed if documentation is not provided. Providing false information can carry penalties under Grenadian law and the law of other countries.
