Personal Income in Australia (PIA), along with Jobs in Australia (JIA), is one of two releases containing data from the Linked Employer-Employee Dataset (LEED). The Jobs and Income of Employed Persons, 2021-22 TableBuilder product contains more detailed data from the LEED.
Revisions due to the inclusion of non-lodgers
Non-lodgers are individuals who do not lodge a tax return. This can include employees who have employee income reported by their employers, persons who receive an income below certain levels (i.e. the tax-free threshold), or persons who derive their income from some Commonwealth of Australia Government pension, benefit and allowance payments that are exempt from income tax. Due to the unavailability of detailed age and sex data, non-lodgers who have employee income have previously been excluded from download tables 1, 2 and 4.
From this release, detailed age and sex data will include non-lodgers with employee income in download tables 1,2 and 4 for all years from 2017-18 and 2021-22. As a result, key statistics, including total personal income, median total personal income, proportion of employee income in total personal income, sources of person income and Gini coefficients are revised relative to estimates for previous reference years, from 2017-18 to 2020-21.
Other standard revisions
Whilst the majority of revisions to data from 2017-18 to 2020-21 reflect the inclusion of non-lodgers, revisions to data also includes standard revisions. Standard revisions are the result of reprocessing historical data (i.e. with updated records or missing information) which usually result in very minor differences to previous years.
