The Foreign Account Tax Compliance Act (FATCA) is a United States law that requires certain financial institutions and other non-financial entities outside the US to report information about financial accounts held by US persons. Failure to comply may result in withholding on certain payments.


FATCA Registration and Reporting

  • If your organisation is required to report under FATCA, you must first register with the US Internal Revenue Service (IRS) using the FATCA Registration Website.

  • Once approved, the IRS will provide a Global Intermediary Identification Number (GIIN), which must be included in all FATCA reports.

  • All FATCA reports must be prepared in XML format, following the FATCA XML Schema and User Guide provided by the IRS.


FATCA Reporting in Australia

  • The Australian Tax Office (ATO) provides the Small Reporter Tool for organisations with up to 50 individual and 50 organisational reportable accounts. This tool helps you prepare and submit your FATCA report.

  • For volumes exceeding these limits, please contact Caruso for support in generating the required XML file.

  • The Small Reporter Tool can also be used to lodge a nil report if there are no reportable accounts for the reporting period.
