Foreign Account Tax Compliance Act (FATCA)

This page provides links and information for FATCA reporters and digital service providers.


The Foreign Account Tax Compliance Act (FATCA) was enacted by the United States Congress in March 2010 to improve compliance with US tax laws. FATCA imposes certain due diligence and reporting obligations on foreign (non-US) financial institutions, including Australian institutions. These institutions will be required to report to the US Internal Revenue Service (IRS) information on US citizens with financial accounts. 


The FATCA reporting period is for 1 January to 31 December in a calendar year. The report is due to be lodged by 31 July the following year.

FATCA reports must be lodged through the Business Portal and Tax Agent Portal.

Testing is now available through the File transfer test facility.

Once you send your report to us, we will send the information on to the IRS.

News and updates

Single file limitation and extension of BDE functionality

Under the solution to be implemented on 1 January 2018, lodgment of FATCA files will be limited to a single report per file. The report should contain all of an entity's reportable accounts.

However current BDE FATCA functionality, which enables the submission of a file for more than one rreporting institution, will continue until approximately December 2018.

New requirements for DocRefID

A new mandatory data format for the DocRefID data elements took effect from 1 January 2016 and applies to all reports lodged to us after that date, including re-lodgments for prior reporting years.

The data format is <reporting FI GIIN><period character (.)><unique value across all time for the reporting FI>

  • The first part – <reporting FI GIIN> is the GIIN for the reporting FI associated with the reporting group
  • The second part is a period character (.)
  • The third part – <unique value across all time for the reporting FI> is an identifying value for the referenced record that is unique within the reporting FI for all time.

This element should contain at least 21 characters, which includes the first part – reporting FI GIIN, the second part – period character (.), and at least one alphanumeric character to represent the third part. The maximum length of DocRefID is 200 characters.

DocRefID Examples:

Each DocRefID within the report needs to be unique.

For void or corrected reports, the new format does not apply to the CorrDocRefIDs as they must be the DocRefID from the original report that generated the error.   


Each MessageRefId in the FATCA report can only ever be used once by the ReportingFI. If a MessageRefId is used more than once an error notification will issue and the file will not be processed by the Internal Revenue Service (IRS).

Account holder Tax Identification Number (TIN)

From 1 January 2017 Pre-existing Account Holder’s TIN must be reported. For reporting years prior to this, we recommend reporting nine zeros in this sub-element.
