Investing in a PIE could influence your other Inland Revenue responsibilities. It is less likely to have an effect if the income is from a locked-in PIE (KiwiSaver, retirement saving scheme or superannuation fund).
Income from a locked-in PIE will not affect your Working for Families Tax Credits or your student loan repayment obligations. Other PIE income will affect your Working for Families Tax Credits and should be included in the IR215.
Your child support payments are not affected if you PIE income does not have to be included in your income tax assessment.
If you have included income from a locked-in PIE in your income tax assessment, you can exclude it from your income by completing the IR215.
