COMMON IR3 ITEMS TO CHECK

  • Final income summary agrees to payslips and myIR.
  • Include untaxed or under-taxed income over $200 where required.
  • Check RWT, dividend credits, PIE credits and schedular tax deducted.
  • Donation tax credits are usually claimed separately, not directly in IR3.

IMPORTANT NOTES

  • For salary/wage earners, ACC earners levy is normally included in PAYE and should be separated when checking income tax payable.
  • IETC depends on eligibility, income level, and whether excluded assistance was received.
  • This calculator does not calculate student loan, Working for Families, child support, or KiwiSaver.
  • Use myIR / final IR3 assessment as the source of truth before payment.
