  • Unique identifiers

    There are two types of unique identifiers used to ensure corrections or amendments can be aligned to the correct report and account information.

    • Unique message identifier (MessageRefId) – identifies the specific report and appears once (C7) in the Report information tab.
    • Document reference (DocRefId) – identifies the specific data element within the report and appears in the      
      • Report information (C26)
      • Individual accounts in column AM for each account reported
      • Organisation accounts in column BE for each account reported.

    These elements must be unique across all time and space, meaning it can only ever be used once.

    In all CRS files the Unique message identifier and Document reference elements must be in the following format:

    • AUReportingYearAUSendingCompanyINUniqueReference for example      
      • AU2017AU12345679121RBF123

    This format has been built into the spreadsheet.

    The Unique message identifier is automatically populated based on the following:

    • AU – the reporter’s Country of residence
    • C6 – the reporting year reported in the Reporting period end date
    • AU – the reporter’s country of lodgment
    • C2 – Sending company Id number
    • C7 – Unique message identifier/

    The Document reference is automatically populated based on the following:

    • AU – the reporter’s Country of residence
    • C6 – the year reported in the Reporting period end date
    • AU – the reporter’s country of lodgment
    • C2– Sending company Id number
    • Unique document identifiers      
      • Report information C25
      • Individual accounts AL3 – AL52
      • Organisation accounts BD4 – BD53/

    The Unique message identifier and Document reference will not automatically populate if the Sending company Id number is invalid. If this occurs you need to correct the ABN, TFN or GIIN in the Sending company Id (C2).
