What FATCA obligations apply to a Cayman Islands fund or company?

A Cayman Islands fund or company subject to the Foreign Account Tax Compliance Act (FATCA) must classify itself typically as a Foreign Financial Institution (FFI) or a Non-Financial Foreign Entity (NFFE), or in some cases as a Non-Reporting Financial Institution or exempt beneficial owner). It must also perform due diligence on its account holders and investors, register with the United States Internal Revenue Service (IRS) if required, and report annually to the Cayman Islands Tax Information Authority (TIA).

The Cayman Islands FATCA framework

FATCA was enacted by the United States Congress in 2010 as part of the Hiring Incentives to Restore Employment (HIRE) Act and became effective for Cayman Islands entities from 1 July 2014. Rather than requiring Cayman entities to report directly to the IRS, the Cayman-US Model 1 IGA establishes a government-to-government reporting mechanism: Cayman Islands Reporting Financial Institutions report to the Cayman Islands Tax Information Authority (TIA), which then transmits that information to the IRS. This structure is automatic exchange of information (AEOI) under FATCA.

Classifying your entity: FFI or NFFE?

The first FATCA obligation for any Cayman entity is to determine its classification. A Foreign Financial Institution (FFI) is broadly defined and includes investment funds, hedge funds, private equity funds, feeder funds, and certain SPVs that meet the definition of an Investment Entity.

A Non-Financial Foreign Entity (NFFE) is any entity that is not an FFI. NFFEs are divided into Active NFFEs (entities whose income and assets are predominantly non-passive) and Passive NFFEs (entities that do not meet the Active NFFE test). Passive NFFEs must identify and disclose any Substantial US Owners, meaning any US person holding more than 10% of the entity by vote or value, to the withholding agent or financial institution through which they receive payments.

Obligations for Reporting Financial Institutions

A Cayman Islands entity classified as a Reporting Financial Institution (RFI) under the IGA must:

1. Register with the IRS on the FATCA Registration Portal to obtain a Global Intermediary Identification Number (GIIN);
2. Conduct due diligence on existing accounts and new accounts opened on or after 1 July 2014 to identify US reportable accounts;
3. Prepare an annual FATCA return disclosing required account information for each US reportable account; and
4. Submit that return to the TIA via the Cayman Islands Financial Account Reporting System (CFARS) by 31 July each year for the prior calendar year. Required information includes the account holder’s name, address, US taxpayer identification number (TIN), account number, account balance or value, and income or proceeds credited to the account.

Non-Reporting FFIs and exempt entities

Not all FFIs are required to register and report.

Under Annex II of the Cayman-US IGA, certain categories of entities are treated as Non-Reporting Cayman Islands Financial Institutions and are deemed compliant without registration. These include: Cayman Islands Government entities; international organisations; certain exempt collective investment vehicles; certain retirement or pension funds; and trustee-documented trusts where the trustee is a Reporting FFI.

Entities qualifying for Non-Reporting status should document their classification and retain evidence of why they qualify, as they may need to confirm their status to withholding agents paying US-source income.

Withholding consequences for non-compliance

FATCA imposes a 30% withholding tax on withholdable payments made to non-compliant FFIs. Withholdable payments include US-source interest, dividends, rents, salaries, annuities, and certain other fixed or determinable annual or periodic income, but not gross proceeds from the sale of US securities, which were removed from the definition of withholdable payments by Treasury regulations effective 2019.

A Cayman fund that holds or expects to receive US-source income and fails to register as a Reporting FFI, or whose GIIN does not appear on the IRS-published FFI List, risks having 30% withheld on those payments. Even funds with limited US investments must assess their FATCA classification carefully to avoid unexpected withholding costs.

Annual reporting deadlines and nil returns

The annual FATCA reporting deadline in the Cayman Islands is 31 July.

Returns must be submitted via the CFARS portal maintained by the TIA. Importantly, the filing of FATCA nil returns is non-mandatory under the Cayman FATCA Regulations: Reporting Financial Institutions with no US reportable accounts in a given year are not required to file a nil return, although the CFARS portal provides a voluntary facility to do so and many practitioners submit nil returns as a matter of good practice.

Failure to submit an annual return where US reportable accounts do in fact exist can result in enforcement action by the TIA under the Tax Information Authority Law (2021 Revision) and related regulations.
