FAQ
Do Singapore institutions report FATCA data directly to the IRS?
No. Singapore has a Model 1 IGA. Singapore Reporting Financial Institutions report FATCA data to IRAS, which then exchanges information with the IRS. IRS registration (GIIN) and ongoing FATCA compliance remain required for in-scope Singapore institutions.
Is IRS registration still required under the Singapore–US FATCA IGA?
Yes. Reporting Singapore financial institutions need a valid GIIN and must apply the FATCA due-diligence rules, including collection and reporting of US TINs where required. Our START module covers IRS registration and GIIN housekeeping for Singapore institutions.
How do you ensure data quality for IRAS FATCA reporting?
We run structured validation and plausibility checks before any submission to IRAS. This includes completeness checks (GIIN/TIN, classifications, address data), basic reconciliations and review of IRAS error files. Issues are addressed before the final filing and documented in an evidence pack.
