PIR thresholds 2025–26

These are set by the Income Tax Act — they're different from your PAYE income tax brackets.

Check annually

Your PIR is based on a rolling two-year window. A pay rise, a new rental property, or a change in PIE income can all shift your correct rate. Your fund will never update it automatically — you have to notify them.

What is PIE income?

It's the income attributed to you from your KiwiSaver or PIE fund during the year. Find it on the annual tax certificate your fund issues after 31 March. You can also see it in myIR.

28% is the cap

Even if your marginal tax rate is 33% or 39%, your PIR is capped at 28%. This is one of the main tax advantages of holding investments through a PIE fund.
