What is the Prescribed Investor Rate (PIR)?

The Prescribed Investor Rate (PIR) is the tax rate applied to your share of investment income inside a Portfolio Investment Entity (PIE) — including KiwiSaver funds, managed funds, and listed PIEs. There are three NZ-resident PIR options for 2027: 10.5%, 17.5%, and 28%. The PIR is the FINAL tax — when you withdraw your funds, there is no further income tax. This makes choosing the right PIR critical, because under rules in effect since 2020, IRD cannot refund overpayments if you used a higher PIR than required.

How the IRD two-year test works

To pick the right PIR, look at your taxable income (excluding PIE) for the last TWO completed years. Take the LOWER of the two. Then apply this test: if income ≤ NZ$14,000 AND combined income+PIE ≤ NZ$48,000 → 10.5% PIR; if income ≤ NZ$48,000 AND combined ≤ NZ$70,000 → 17.5% PIR; otherwise 28% PIR. Use the lower-year rule even if this year's income is higher — that's how IRD designs the system to avoid year-to-year flipping.

Example: part-time worker with KiwiSaver

Sarah earned NZ$25,000 in 2025 and NZ$28,000 in 2026 (taxable, excluding PIE). Her KiwiSaver returned NZ$3,000 in 2025 and NZ$3,500 in 2026. Lower year: 2025 — NZ$25,000 income + NZ$3,000 PIE = NZ$28,000 combined. Income ≤ NZ$48,000 AND combined ≤ NZ$70,000 → 17.5% PIR applies. Her 2026 KiwiSaver tax = NZ$3,500 × 17.5% = NZ$612. If she had defaulted to 28% PIR, tax would have been NZ$980 — and IRD would NOT refund the NZ$368 difference. PIR matters.

How to use this PIR calculator

Enter your taxable income (salary, wages, interest, dividends — excluding PIE) for the last two completed years, plus your PIE income for each year. The calculator applies IRD's two-year lower-test and tells you your correct PIR. Then update each KiwiSaver / fund provider via their online portal. Re-check your PIR every April when the new tax year starts.
