Key Takeaways
- FATCA reaches Anguilla entities and accounts through an intergovernmental agreement with the US, even where owners are non-resident.
- Many Anguilla entities qualify as foreign financial institutions and must register for a GIIN and report accounts linked to US persons.
- Reporting flows from Anguilla institutions to the IRS, and gaps can trigger 30 percent withholding alongside other non-compliance consequences.
- Owners holding Anguilla structures should confirm FFI classification, identify any US persons, and keep registration and reporting current.
FATCA and Anguilla: Where the Caribbean Territory Stands with US Tax Reporting
FATCA in Anguilla operates through a Model 1B intergovernmental agreement with the United States, under which Anguilla financial institutions report US account information to a local authority that forwards it to the IRS. The framework is administered on-island by the International Tax Cooperation Department (ITCD), and the agreement itself is published in full by the US State Department. It affects any Anguilla-incorporated company, trust, fund, or partnership that holds financial accounts connected to a US person, even where the owner has never set foot in the United States.
This article explains how the agreement works, which entities fall within scope, what registration and reporting it demands, and what happens when an institution fails to comply. It is written for non-resident owners and advisers weighing an Anguilla structure or maintaining one that may touch US persons or US-source income.
The Anguilla-US Intergovernmental Agreement: Model and Current Status
Anguilla is a party to a FATCA intergovernmental agreement with the United States, classified as Model 1B (Nonreciprocal). Under a Model 1 arrangement, local financial institutions report specified US account data to the Anguillian competent authority, which then transmits it to the IRS automatically.
"Nonreciprocal" carries a direct meaning for you: the information flow runs in one direction only. The US does not commit to sending equivalent automatic data back about Anguilla-resident persons holding US accounts.
The agreement sets June 30, 2014, as the operative date for pre-existing accounts, a reference point that also governs certain relief from US TIN-reporting requirements. A double tax convention or a tax information exchange agreement is not a precondition for the agreement to function; a TIEA between the two governments predates it but is not what makes it operate.
Administration sits with the ITCD as the local competent authority. The department confirmed a reporting deadline of May 31, 2025, for FATCA and CRS returns covering the 2024 reportable period.

Why FATCA Reaches Anguilla Entities and Accounts
FATCA was enacted as part of the US HIRE Act. It requires foreign financial institutions to report information about accounts held by US taxpayers, or by foreign entities in which US taxpayers hold a substantial ownership interest, or face withholding on certain US-source payments.
The reach extends to your structure directly. An Anguilla-incorporated company, trust, or fund with even a single US beneficial owner or controlling person falls within scope of the regime.
Anguilla levies no corporate or income tax on offshore entities, which makes its structures a common vehicle for non-resident international planning. The agreement fills the information gap that domestic tax law would otherwise leave open, so compliance carries real weight for foreign owners.
The territory also sits among the first-wave OECD jurisdictions committed to automatic exchange under the Common Reporting Standard, alongside the British Virgin Islands and the Cayman Islands. FATCA and CRS therefore run in parallel for local financial institutions, and an entity in scope of one is frequently in scope of both.
Which Anguilla Entities Count as Foreign Financial Institutions
The regime sorts entities into two broad categories: foreign financial institutions (FFIs) and certain non-financial foreign entities (NFFEs). Every Anguilla entity must be placed in one of these before any obligation can be assessed.
An FFI under the agreement falls into one of four functional types:
- Depository institutions, such as banks.
- Custodial institutions.
- Investment entities, including funds, portfolio managers, and discretionary asset managers.
- Specified insurance companies issuing cash-value insurance or annuity contracts.
An entity may meet more than one of these definitions, and all must be considered before its status is settled. The agreement also permits local institutions to apply US Treasury Regulation definitions in place of the corresponding agreement definitions, provided doing so does not frustrate the agreement's purpose.
Several common offshore vehicles qualify as investment-entity FFIs: International Business Companies, trusts where a trustee that is itself a financial institution acts on the structure's behalf, and limited partnerships run by a professional fund manager. Each is subject to classification review under the due-diligence procedures in Annex I.
An IBC managed by a professional manager will often be an FFI, while a passively held company may be an NFFE. The classification determines who registers, who reports, and who must collect owner documentation.
Local retirement plans receive separate treatment. Arrangements established and regulated under Anguilla law to provide pension or retirement benefits are treated by the United States as deemed-compliant FFIs or exempt beneficial owners, as appropriate.
The agreement also distinguishes "Non-Reporting Anguilla Financial Institutions," the exempt and deemed-compliant categories, from institutions whose branches sit in jurisdictions that prevent FATCA compliance.

Identifying a US Person Under FATCA in the Anguilla Context
A "US taxpayer" for these purposes includes US citizens, US residents holding a green card or meeting the substantial presence test, and certain US-formed entities. US citizenship is the central trigger, because the US taxes its citizens on worldwide income regardless of residence.
A US citizen holding an interest in an Anguilla IBC or trust is in scope even if they have never lived in the United States. That single connection can render an account reportable.
Under the Annex I due-diligence rules, a non-US entity becomes a US reportable account when one or more of its "controlling persons" is a "Specified US Person." Reporting then captures the entity's name and address, together with the US TIN where one exists.
Trust structures demand particular care. An equity interest in a trust that is a financial institution is treated as held by any settlor, any beneficiary of all or part of the trust, and any natural person exercising ultimate effective control. In practice, all relevant roles, settlor, beneficiary, protector, and controlling person, must be reviewed for US status.
For pre-existing accounts held as of June 30, 2014, an institution that does not hold a relevant person's US TIN in its records is not required to obtain it, but must report the date of birth instead.
GIIN Registration and Reporting Obligations for Anguilla FFIs
The IRS issues a Global Intermediary Identification Number, a 19-character code, to each Anguilla financial institution that completes FATCA registration through the IRS online system. Registration is handled on the FATCA Registration Website, a secure portal accessible from anywhere at any hour.
Once approved, the institution and its branches receive their GIINs, and the institution uses that number to identify itself to withholding agents and tax administrators. No registration fee is documented; the IRS portal operates without charge.
Approved institutions appear on the IRS FFI List, refreshed on the first day of each month. The list includes only entities in approved status on that day that were approved at least five business days earlier.
Registration is distinct from certification. Responsible officers of certain entities must submit two types of certification to the IRS: one addressing pre-existing accounts and a periodic certification covering overall compliance.
The on-island filing is separate again. The ITCD confirmed May 31, 2025, as the deadline for FATCA returns covering the 2024 reportable period, a submission made to the Anguillian competent authority rather than to the IRS directly.
You can confirm whether an institution holds a valid GIIN through the IRS search tool.

How FATCA Reporting Flows from Anguilla to the IRS
Under the Model 1 mechanism, a reporting institution does not report to the IRS directly. It identifies US accounts using the Annex I due-diligence rules, reports the specified information to the ITCD, and the ITCD passes it on to the IRS automatically.
Because the agreement is nonreciprocal, only the Anguilla-to-IRS flow is required. The reported data must include the US TIN for each Specified US Person who is an account holder and for each US person treated as a controlling person of certain accounts held by a non-US entity.
Technical transmission runs through the International Data Exchange Service (IDES). A reporting institution, or an entity acting for it, must make a written election and deliver it to the US Competent Authority before uploading or downloading through that service.
Where pre-existing account holders refuse consent to reporting, the institution reports aggregate information instead. On that basis the IRS may make a "group request" to the ITCD for more specific detail. The Anguillian authority is bound to maintain confidentiality over information it receives back from the US side through IDES.
Withholding Exposure and the 30 Percent Penalty Risk
FATCA carries a 30% withholding tax on US-source interest, dividends, and other financial payments. The mechanism is designed to compel participation: an institution in a jurisdiction without an agreement in effect must register and agree to an FFI agreement, or obtain deemed-compliant status, to avoid being withheld upon.
Because Anguilla has a Model 1 agreement in effect, compliant local institutions are not themselves required to withhold on US-source payments. The withholding obligation rests with US payors dealing with non-compliant institutions.
The protection is conditional. An institution that fails to meet its agreement obligations, including adequate reporting, may be treated as in "significant non-compliance," and if that is left unresolved it can become subject to the 30% withholding on certain US-source receipts.
The United States will also not require a reporting institution to withhold on a recalcitrant account holder's account, provided the required information reaches the US Competent Authority through the ITCD. Losing that relief is the practical incentive to file accurately and on time, since recovering an overpaid withholding amount can demand considerable effort from account holders.
Non-Compliance Consequences for Anguilla Institutions and Owners
Removal from the IRS FFI List is the headline sanction. Where an issue of significant non-compliance is not resolved within 18 months, a registered Anguilla institution is taken off the list, exposing its US-source receipts to withholding.
The Competent Authority Arrangement gives concrete examples of significant non-compliance. These include failure to report information on US reportable accounts as the agreement specifies, and failure to correct administrative errors on time, which the US Competent Authority may at its discretion treat as significant non-compliance.
Failure to report required US TINs can prompt the US authority to notify the ITCD that an institution is significantly non-compliant. The United States may then treat that institution as a nonparticipating financial institution subject to withholding. A related entity or branch operating in a jurisdiction that prevents compliance can itself be treated as nonparticipating.
The exposure reaches owners differently where the structure is a passive NFFE rather than an FFI. In that case the bank or other account-holding institution must collect information on substantial US owners, and a failure to provide it can trigger account closure or withholding at source.
Local enforcement continues to develop. Amendments to the International Tax Compliance (CRS) Regulations, 2016, made on July 26, 2024, introduced new compliance provisions for financial institutions, an indication that the on-island framework backing these obligations is being tightened over time.
Practical Steps for Non-Resident Owners Holding Anguilla Structures
Work through the obligations in order, starting with the question that drives everything else: how each entity is classified.
- Classify each entity. Determine whether your IBC, LLC, trust, partnership, or fund is an FFI, a passive NFFE, or an active NFFE before anything else.
- Register for a GIIN where required. An FFI registers on the IRS FATCA Registration Website and receives its GIIN on approval; the portal is available worldwide and charges no fee.
- Collect documentation from account holders. Gather W-8 and W-9 forms under the Annex I rules, and apply re-certification procedures for new and existing accounts.
- File annual returns on time. The deadline for the 2024 reportable period was May 31, 2025; timely filing with the ITCD avoids a significant non-compliance finding.
- Use the TIN-relief window. IRS Notice 2024-78, issued October 2024, extends temporary relief from significant non-compliance for missing US TINs on pre-existing accounts through calendar years 2025, 2026, and 2027; solicit the missing numbers during that period.
- Verify GIIN status monthly. Check the IRS-published FFI list, since an institution that loses its GIIN exposes your US-source receipts to 30% withholding.
The ITCD is the on-island point of contact for registrations, returns, and compliance questions; reach it through official Anguilla government channels. Owners advised by US tax counsel should confirm the chosen classification holds consistently under both the agreement and the US Treasury Regulations, since the agreement permits institutions to apply the regulation definitions where doing so does not undercut its purpose. The full list of partner agreements is maintained by the US Treasury.
Conclusion
FATCA applies to Anguilla through a live Model 1B agreement, so a foreign-owned company, trust, or fund with any US connection sits squarely within its reporting reach. The practical work falls on classification, GIIN registration where needed, accurate collection of account-holder documentation, and meeting the annual ITCD filing deadline. Get those right and the 30% withholding exposure stays off the table; let them slip toward significant non-compliance and the institution risks removal from the IRS list. For non-resident owners, the message is straightforward: an Anguilla structure carries real US reporting duties, and they are best managed with proper classification and timely filing from the outset.

Frequently Asked Questions
Yes. The territory is a party to a Model 1B intergovernmental agreement with the United States, administered locally by the International Tax Cooperation Department, under which financial institutions report US account information to the IRS through that department.
It means information moves in one direction only: Anguilla institutions report to the IRS, but the United States does not commit to sending equivalent automatic data back. For your structure, the practical effect is that all reporting obligations run toward the IRS.
The ITCD confirmed May 31, 2025, as the deadline for FATCA and CRS returns covering the 2024 reportable period. This filing is made to the Anguillian competent authority, which then transmits the data to the IRS, rather than to the IRS directly.
Yes. Because the US taxes citizens on worldwide income regardless of residence, a US citizen holding an interest in an Anguilla IBC or trust is in scope even with no physical connection to the United States.
An unresolved issue of significant non-compliance can lead to removal from the IRS FFI List after 18 months, after which the institution's US-source receipts become subject to 30% withholding. Examples of such non-compliance include failure to report US reportable accounts or to report required US TINs.
No fee is documented. The IRS FATCA Registration System operates as a no-cost online portal accessible worldwide, and on approval it issues the institution a 19-character GIIN.
