Matching external data with our own helps us to ensure that people and businesses comply with their tax and super obligations. It also helps us to detect fraud against the Commonwealth.

We are required to comply with strict laws to protect your privacy when we collect data from other agencies and organisations for our data-matching programs. These laws include the Privacy Act 1988, the secrecy provisions of the Income Tax Assessment Act 1936, the Taxation Administration Act 1953 and other tax laws.

We also adhere to the Privacy Commissioner's Guidelines on Data Matching in Australian Government AdministrationExternal Link by preparing and publishing a protocol for each of our data-matching programs.

In broad terms, each protocol explains:

  • the purpose of the program
  • what data is collected
  • which agencies or organisations will be providing the data
  • how the data will be used.
