• Data matching

    Data matching is a powerful administrative and law enforcement tool; with information from a variety of third-party sources compiled electronically, validated, analysed and used for a range of education and compliance activities.

    Data matching makes it possible for us to ensure that people and businesses:

    • lodge tax returns and activity statements when required to do so
    • correctly declare their income and claim offsets and other benefits
    • comply with their obligations.

    It allows us to detect people and businesses operating outside the tax system, detect fraud against the Commonwealth, and recover debt.



    This video outlines how we use data matching to identify people who are doing the wrong thing. Duration 2:10. A transcript of It’s not worth the risk is also available.
