Concept: CRS vs. US FATCA: Key Differences
While both the Common Reporting Standard (CRS) and the Foreign Account Tax Compliance Act (FATCA) are designed to promote automatic exchange of financial account information (AEOI), they operate under different legal frameworks. In the Cayman Islands, both are implemented via local regulations, but key differences exist that impact day-to-day compliance.
Side-by-Side Comparison
| Feature | US FATCA | OECD CRS |
|---|---|---|
| Primary Scope | US citizens, green card holders, and US tax residents globally. | Tax residents of participating CRS jurisdictions (over 100 countries). |
| Citizenship Trigger | Yes. A US citizen is reportable even if resident in the Cayman Islands. | No. Reports are based strictly on tax residency, not citizenship. |
| Nil Returns | Mandatory for Cayman Model 1 IGA. | Mandatory in the Cayman Islands. |
| Entity Exclusions | Exemptions for many local FIs, small banks, and retirement funds. | Very narrow exemptions. Fewer NRFIs than under FATCA. |
| De Minimis Thresholds | Generally exempts individual preexisting accounts under $50,000. | No de minimis threshold for individual accounts. |
| Entity Classification | Uses the term Non-Financial Foreign Entity (NFFE). | Uses the term Non-Financial Entity (NFE). |
| Sponsored Entities | Allows "Sponsored FIs" to use the sponsoring entity's GIIN. | Does not support sponsoring concepts. Each RFI must register individually. |
Sponsoring and Registration Differences
- FATCA Sponsoring: Under FATCA, fund managers can act as a "Sponsoring Entity" for multiple investment funds, allowing the sponsor to perform due diligence and reporting on behalf of the "Sponsored FIs" under the sponsor's GIIN.
- CRS Individual Responsibility: CRS does not recognize sponsored entities. Every Cayman Reporting Financial Institution (RFI) must register individually on the DITC Portal and submit returns under its own unique Organisation ID (Ref ID), even if it outsources the reporting activity to a third-party administrator.
Entity Classification Nuances
An entity might be classified differently under the two regimes. For example, certain investment managers are non-reporting under FATCA but are classified as Reporting FIs under the CRS. Due to these nuances, Self-Certifications are designed to capture both FATCA and CRS statuses separately on the same form.
