    Taxation statistics - whole document


    This year the ATO embarked on an ambitious project to produce and release a confidentialised 1% sample file containing individual tax return information. This was an attempt to satisfy the requirements of more advanced users of taxation data and further demonstrates the ATO's commitment to an open and transparent tax system.

    The file is confidentialised in order to protect the identities of those contained in the file. This year we are releasing two sample files. A file for the 2005-06 income year based on data contained in Taxation statistics 2005-06 and a file for the 2006-07 income year based on data in Taxation statistics 2006-07. Each year the file will be released in conjunction with the release of Taxation statistics.

    The data used to compile the 2005-06 unit record sample file has been sourced from the 2005-06 individual income tax returns processed by 31 October 2007. The 2006-07 unit record sample file has been sourced from the 2006-07 individual income tax returns processed by 31 October 2008.


    Some key information about the 2005-06 and 2006-07 sample files:

    • The files represent 1% of returns lodged by individuals
    • Each file contains around 115,000 individual records
    • The files contains 49 data items, including demographic information such as gender, marital status, year of birth (five year range), occupation code (one digit level) and a geographic region based on postcodes.
    • The remainder of the data items are income, deduction, losses and some other indicators sourced from the individual tax return.
