Summary

This is the consolidated 2021 Revision of the Cayman Islands regulations that implement the Cayman Islands–United States FATCA Intergovernmental Agreement (IGA) domestically. The Regulations set out the definitions (Financial Institution, Reporting Financial Institution, Non-Reporting Financial Institution, NFFE, Reportable Account, Specified Person, etc.) and the operative rules that Cayman-based Financial Institutions must follow to identify, document and report US reportable accounts to the Cayman Tax Information Authority (the Competent Authority), which in turn exchanges the information with the US Internal Revenue Service.

The Regulations apply to any person carrying on business in the Cayman Islands as a custodial institution, depository institution, investment entity or specified insurance company (i.e. a "Financial Institution" under the Regulations), distinguishing between Reporting Financial Institutions and Non-Reporting/Registered Deemed-Compliant Financial Institutions. They cover the following areas:

  • Registration: Registration with the US IRS.
  • Due diligence: Due diligence and identification of account holders, including modified due diligence for certain account types.
  • Reporting: Annual reporting obligations.
  • Non-participating institutions: Special rules for non-participating financial institutions.
  • Anti-avoidance: Anti-avoidance provisions.
  • Notification: Notification duties to the Competent Authority.
  • Compliance powers: Inspection and compliance powers.
  • Offences: Offences for non-compliance, including director/officer liability.
  • Third-party agents: The ability to appoint third-party agents.
  • Guidance: The Competent Authority's power to issue guidance.

This 2021 Revision consolidates the original 2014 Regulations with subsequent 2015, 2018 and 2020 amendments and is presented as the current in-force text as at 31 December 2020; it does not itself introduce new substantive changes beyond consolidating prior amendments.
