Data matching

Data matching is an administrative and law enforcement tool we use for education and compliance activities.

Last updated 11 May 2023

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

Data matching allows us to:

  • pre-fill tax returns, making it easier for everyone to lodge their tax
  • reassure the community that we protect honest people and businesses from unfair competition
  • ensure 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.
  • detect people and businesses operating outside the tax system
  • detect fraud against the Commonwealth
  • recover debt.

We run our data matching programs throughout the year, specifically when you lodge your tax return as well as after you receive your tax assessment.
