  • Average taxable professional income (ATPI)



    This information may not apply to the current year. Check the content carefully to ensure it is applicable to your circumstances.

    End of attention

    Generally, average taxable professional income (ATPI) in an income year is one-quarter of the sum of the TPIs for the preceding four years. Special rules apply for working out the ATPI where your income averaging year 1 was less than four years ago. So, in the first four years, ATPI is worked out as follows:

    • year 1 nil
    • year 2 one-third of TPl in year 1
    • year 3 one-quarter of TPI in years 1 and 2
    • year 4 one-quarter of TPl in years 1, 2 and 3.

    If you were not a resident at any time during the year immediately before your year 1, phone the Tax Office.
