Ireland — Regulatory Framework
Overview of the key legal sources, competent authorities and technical standards in Ireland for FATCA (Model 1 IGA), CRS/DAC2 and the QI regime – including interfaces and practical notes for Irish financial institutions.
Key points
- FATCA is implemented via a Model 1 IGA: reporting to Revenue (Irish Tax and Customs), which forwards data to the IRS.
- CRS/DAC2 is implemented in Irish law and operated via Revenue’s AEOI framework.
- QI remains a US regime (IRS) but can rely on Irish Approved KYC Rules for documentation checks.
Who is in scope?
- Banks, custodians, brokers, MiFID firms and other Irish Reporting FIs.
- Investment funds, management companies and other collective investment vehicles.
- Insurance companies with relevant cash value / annuity products.
1) Legal sources (selection)
| Area | Source | Content / focus |
|---|---|---|
| FATCA (IGA) | US–Ireland FATCA Intergovernmental Agreement (Model 1) + Annex I/II | Definitions, due diligence and reporting requirements; Annex II exemptions for specific Irish entities/products. |
| FATCA (domestic) | Section 891E TCA 1997; Financial Accounts Reporting (United States of America) Regulations 2014 (S.I. 292/2014) as amended | Domestic implementation of the IGA: reporting obligations, Revenue’s powers and AEOI framework. |
| CRS / DAC2 | Sections 891F & 891G TCA 1997; CRS/DAC2 regulations and Revenue guidance | Automatic exchange of information under CRS and the EU Directive on Administrative Cooperation (DAC2) for non-resident account holders. |
| QI | IRS QI Agreement; Approved KYC Rules (Ireland) | US withholding and documentation regime; recognition of Irish KYC processes for W-8/W-9 review. |
| AML / KYC | Criminal Justice (Money Laundering and Terrorist Financing) Acts; Central Bank of Ireland guidance | Customer due diligence, ongoing monitoring and governance – foundation for “reason-to-know” and documentation quality. |
| Data protection | GDPR; Data Protection Act 2018; AEOI-related provisions in TCA 1997 | Legal basis for processing and transmitting account data; information requirements, retention and security. |
2) Responsibilities
- Revenue Commissioners: competent authority for FATCA and CRS/DAC2 in Ireland; receipt, validation and onward transmission of AEOI data.
- Central Bank of Ireland (CBI): prudential and conduct supervision, including AML/CFT frameworks, governance and outsourcing.
- Financial institutions: customer due diligence, classification, data capture, reporting and remediation of errors.
- IRS: primary supervisor for QI (QI Agreement, Periodic Review, certifications and potential sanctions).
3) Interfaces: FATCA ↔ CRS/DAC2 ↔ QI
- Consistency of identifiers (US TIN, Irish TIN where applicable, GIIN), customer data and documentation status across all regimes.
- Annex II exemptions (FATCA) vs. CRS/DAC2 obligations need to be clearly mapped for each product line and entity type.
- KYC synergies: Irish KYC processes can support QI and CRS/FATCA due diligence, but tax-specific requirements (e.g. self-certifications, W-forms) must still be met.
4) Technical standards (high level)
- FATCA and CRS XML prepared in line with the latest Revenue filing guidelines and schema versions.
- Electronic submission via ROS / AEOI channels with appropriate digital certificates and encryption.
- Change management process for schema updates, new validations and Revenue/IRS guidance; test submissions before go-live where feasible.
- Defined process for corrections/voids/amendments with stable record keys and audit trail.
