  • Validating the data we receive

    Legislated data collected from third-party providers is sent to us in reports through a secure electronic channel. Each report contains information such as tax file number (TFN), name and date of birth, to allow us to match it to the correct person.

    Integrity checks are conducted to confirm the quality of the data, including:

    • checking the data provider’s identity to prevent possible fraudulent reports
    • checking for duplicate reports, so we don’t end up with two sets of data – if a second data set is received we generally reject the earlier one
    • matching reported data to valid TFN records in our systems
    • ensuring overall integrity by identifying recurring quality issues in the data collecting and matching process.

    Once a report has passed our integrity checks, we use algorithms and other analytical methods to refine the data. This validated data is then matched to information reported in tax returns.

    The data we collect for specific data-matching projects is often sourced from providers' systems and may not be available in a format that can be readily processed by our systems. In these instances, we apply extra levels of scrutiny and analytics to verify the quality of the data before matching data to taxpayers' returns.
