    Taxation statistics - whole document


    In the Taxation statistics 2006-07 publication, the ATO released confidentialised 1% sample files containing individual tax return information. This was an attempt to satisfy the requirements of more advanced users of tax data and further demonstrates our commitment to an open and transparent tax system.

    The files are confidentialised in order to protect the identities of those contained in the files. Last year, sample files were released for the 2003-04 to 2008-09 income years. The data in these sample files was based on data contained in Taxation statistics for each of these income years.

    This year we are releasing the sample file for the 2009-10 income year based on data contained in Taxation statistics 2009-10.


    In summary, the 2009-10 sample file:

    • represents 1% of returns lodged by individuals
    • contains around 124,000 individual records
    • contains 50 data items, including demographic information such as gender, marital status, year of birth (five-year range), occupation code (one digit level) and geographic region (based on postcodes) - the remainder of the data items are income, deductions, losses and some other indicators sourced from individual tax returns.
