FAQ
Do Australian institutions report FATCA data directly to the IRS?
No. Australia has a Model 1 IGA. Australian financial institutions report FATCA data to the Australian Taxation Office (ATO), which then exchanges information with the IRS. IRS registration (GIIN) and ongoing FATCA compliance remain required for in-scope Australian institutions.
Is IRS registration still required under the Australia–US FATCA IGA?
Yes. Reporting Australian 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 Australian institutions.
How do you ensure data quality for ATO FATCA reporting?
We run structured validation and plausibility checks before any submission to the ATO. This includes completeness checks (GIIN/TIN, classifications, address data), basic reconciliations and review of ATO error files. Issues are addressed before the final filing and documented in an evidence pack.
