  • Data matching

    We receive information from a variety of third-party sources, such as employers and financial institutions. We use this data for a range of activities, including data matching. Matching data ensures that taxpayers declare all their income, offsets and exemptions correctly.

    Pre-filled data is available from 1 July, with most data finalised by the end of July.

    This year we amended over 500,000 individual tax returns before issuing tax assessments. We used third-party data that was available through your pre-fill service yet was omitted from their tax returns.

    We also corrected tax returns for around 150,000 individual taxpayers with discrepancies. We were able to validate information using third-party sources after the issue of their tax assessments.

    With improved data available from more sources, we are expanding our data matching to include areas such as:

    • cryptocurrency transactions
    • sharing economy – accommodation providers
    • property management reports
    • novated lease vehicle information.

    Take extra care when preparing your clients' tax returns at the start of the financial year. Remind your clients they need to provide all the necessary information.
