US tax for banks in Ireland (QI, FATCA, CRS/AEOI)
Welcome to the Ireland hub. This page consolidates key information for financial institutions on the regulatory framework, reporting mechanisms via Irish Revenue, supervision & penalties, QI specifics and local tax/practice points – with links to all underlying pages and service modules.
Highlights (short)
FATCA: Model-1 IGA
Reporting is made to Irish Revenue, which then transmits data to the IRS. Institutions need a GIIN and must collect/report US TINs where required.
CRS/AEOI (OECD standard)
Automatic exchange of information via Irish Revenue; due-diligence and XML formats follow OECD/CRS specifications and Irish AEOI guidance.
See: Reporting mechanisms
QI as US regime
Approved KYC (Ireland) is recognised for QI; nevertheless, W-forms, pooling, 1042/1042-S and the Periodic Review remain central.

FAQ
Do Irish institutions report directly to the IRS?
No. Ireland has a Model-1 IGA; reporting is made to Irish Revenue, which forwards FATCA data to the IRS. Registration with the IRS (GIIN) is still required.
How does QI relate to FATCA/CRS?
QI governs US withholding tax and documentation (W-forms). FATCA/CRS govern due-diligence and reporting to Irish Revenue. Data must be consistent across all regimes.
