US Tax for Banks in Singapore (QI, FATCA, CRS/AEOI)
Welcome to the Singapore hub. This page brings together key information for financial institutions: the regulatory framework, reporting mechanisms via the Inland Revenue Authority of Singapore (IRAS), supervision & enforcement, QI specifics for Singapore-based institutions and local tax features & practical examples.
Highlights (at a glance)
FATCA: Model 1 IGA (Singapore–US)
Reporting is made to IRAS, which then exchanges data with the IRS under the Singapore–US FATCA Intergovernmental Agreement. Institutions need a GIIN and must collect and report US TINs where required.
CRS/AEOI via IRAS
Automatic exchange of information under the OECD Common Reporting Standard (CRS), with Singapore-based financial institutions reporting foreign tax resident accounts to IRAS in prescribed electronic formats.

QI as a US regime
Singapore is on the IRS list of Approved KYC jurisdictions. Still, W-forms, pooling & treaty rates, 1042/1042-S and the QI Periodic Review cycle remain central for Singapore QIs.

FAQ
Do Singapore financial institutions report directly to the IRS?
No. Singapore has a Model 1 IGA; reporting is made to the Inland Revenue Authority of Singapore (IRAS), which then exchanges information with the IRS. However, IRS registration (GIIN) and ongoing FATCA/QI compliance remain required for in-scope Singapore financial institutions.
How do QI and FATCA/CRS fit together in Singapore?
QI is a US withholding and documentation regime focused on US-source income, W-forms, pooling and Forms 1042/1042-S. FATCA/CRS are due-diligence and reporting regimes (with reporting via IRAS for Singapore financial institutions). Data must be consistent across all regimes – KYC, QI, FATCA and CRS/AEOI.
