Your above-average special professional income is the amount of TPI you earned during the income year that is more than your average TPI. Your tax payable is the sum of tax on your above-average special professional income and tax on your other income (step 1 explains ‘other income’). If there is no above-average special professional income (that is, your TPI is equal to or less than your average TPI) you will pay tax at ordinary rates on your taxable income.
Completing your tax return
For us to work out your income averaging, you must complete Z item 24 on your Tax return for individuals (supplementary section) 2016. See step 3 question 24 in Individual tax return instructions supplement 2016 and read the following:
The amount to write at Z item 24 on your tax return (supplementary section) is your assessable professional income less the total of your deductions that reasonably relate to this income. Do not deduct any apportionable deductions, for example, gifts to charity that you have shown at item D9 on your tax return. We will take these into account to work out your TPI and your income averaging.
At V item 24 on your tax return (supplementary section), write the total of your category 2 other income (see step 1 question 24 in Individual tax return instructions supplement 2016), including the amount you wrote at Z item 24. Do not include any amounts already shown at item 1, 2, 13, 14 or 15 on your tax return. If you have not shown your TPI at other items on your tax return, you must include it at V item 24. If you include your TPI at V, do not claim any deductions you used to work out your TPI at items D1 to D10 or D11 to D15 on your tax return.
