  • Navigating Taxation statistics

    The following will help you understand the data in Taxation statistics 2017–18:

    Summary tables and charts

    The summary tables and charts in each section provide an overview of taxation statistics for the topic.

    Below each table and chart is a link to the data in Microsoft Excel spreadsheet format. The spreadsheets include same or similar historical data going back many years.

    Using detailed tables

    Detailed tables contain substantially more data than summary tables and charts. Data about most labels on our most common return forms and schedules are in the detailed tables.

    There are two main ways to identify which detailed tables you want.

    Option 1 – View the detailed tables list in each section

    Go to Statistics for 2017–18 and navigate to the section you are interested in. Select the Detailed tables link to be taken to the list. Select the link to the relevant detailed table. This will take you to data.gov.auExternal Link where all our detailed tables are stored.

    Option 2 – Use the index

    If you are unsure which detailed table contains the information go to the 2017–18 indexExternal Link on data.gov.au. The index covers individuals, companies, super funds, partnerships, trusts and fringe benefits tax (FBT). All item and label descriptions are as per the 2018 income tax return forms and the 2019 FBT return form. The index includes direct links to detailed tables.

    Once you have found the detailed table you want on data.gov.au, select the Download button, then open or save the file.

    Changes in data over time

    We recommend you exercise caution when comparing statistics from current and previous income years.

    Each year we receive lodgments, amendments or cancellations, after the processing cut-off date for the data in the previous publication.

    Additionally, changes in legislation (such as changing income tax rates or thresholds) can impact year-on-year analysis.

    Our detailed tables are updated differently depending on the type of data:

    The currency of the data is documented in the notes tab of each detailed table.

    Previous year data in summary tables and charts is not updated. This allows for a quick year-on-year (point-in-time) comparison.

    Taxation statistics numbers compared to other ATO publications

    There are several reasons why data in this publication may not match data in other ATO, government or non-government publications, including:

    Cut-off processing dates

    We choose a cut-off date of 31 October the following year to compile our statistics. A majority of returns will have been lodged and processed during this 16-month period.

    Data from forms or amendments processed after this cut-off date is not included in the statistics for that year's publication.

    It is likely the statistics will be different in another ATO publication if it uses a different cut-off date, even if it refers to the same income, financial or FBT year.

    The following data is based on income year:

    • individuals
    • companies
    • super funds
    • partnerships
    • trusts
    • capital gains tax (CGT)
    • industry benchmarks (financial ratios).

    The following data is based on financial year:

    • member contribution statement (MCS)
    • goods and services tax (GST)
    • wine equalisation tax (WET)
    • luxury car tax (LCT)
    • petroleum resource rent tax (PRRT)
    • excise and fuel schemes
    • pay as you go (PAYG) withholding and instalments
    • industry benchmarks (activity statement ratios).

    Fringe benefit tax data is based on the FBT year, while cost of tax compliance includes data relating to income, FBT and financial years.
