PIE vs Direct Investment: Which Pays Less Tax in NZ?

A Portfolio Investment Entity (PIE) is a special tax-treatment fund structure used by KiwiSaver providers, managed funds, and most investment products. Income is taxed at the fund level using your Prescribed Investor Rate (PIR) (10.5%, 17.5%, or 28%) — the 28% cap is the main attraction over direct investment, where you'd pay your marginal rate up to 39%.

28%. PIE income at your PIR is final tax for income tax purposes — it doesn't add to your taxable income, push you into a higher marginal bracket, or add to your income for IETC. Working for Families and student loan repayment income work differently and depend on whether the PIE is locked-in: a LOCKED-IN PIE (KiwiSaver, most retirement/superannuation schemes) has no effect on either; a NON-locked-in PIE (a PIE term deposit, a managed fund you can withdraw from, most listed PIEs) DOES count toward Working for Families and student loan income and must be added back through myIR's "Adjust your income" service or an IR215 form (see the return and repayment question below). So a high earner on 39% still pays only 28% income tax on their PIE income (an 11-percentage-point saving on every dollar) — but that saving doesn't extend to a non-locked-in PIE's effect on WfF or student loan obligations.

Your PIR is based on your taxable income across your last 2 completed income years — you only need ONE of those two years to qualify at a given rate, and both conditions in that year's test must hold. For 2025-26: 10.5% applies if, in EITHER of the last 2 years, your taxable income excluding PIE was $15,600 or less AND your taxable income including PIE (less any PIE loss) was $53,500 or less; 17.5% applies if, in EITHER of the last 2 years, taxable income excluding PIE was $53,500 or less AND combined income was $78,100 or less; otherwise 28% (IRD IR861). Use the PIR calculator to work through both years and confirm.

Direct investment income is taxed at your marginal rate — up to 39% above $180,000. PIE caps at 28%. On $10,000 of investment income, that's $2,800 PIE tax versus $3,900 direct tax — a $1,100 annual saving. The gap compounds over decades for KiwiSaver and managed funds.

Two cases, since (per IRD IR860) a qualifying NZ (or certain Australian) share gain is excluded from a PIE's taxable income the same way it's tax-free for a long-term direct holder — capital gains exposure on those shares isn't itself a reason to go direct: (1) You're on the 10.5% marginal rate — direct investment matches PIE at PIR 10.5%. (2) You want to claim foreign tax credits (PIE generally absorbs them; direct holders can claim). Where a PIE genuinely loses this exclusion is on NON-qualifying holdings — foreign shares outside the small approved list, for example — where the PIE's realised gain is taxed as PIE income; a direct holder of the same non-qualifying foreign shares would typically face the FIF rules instead, so that isn't a clean win for direct investment either.

Yes. Almost all KiwiSaver schemes are PIEs, taxed at your PIR. This is why a 39% earner's KiwiSaver compounds at the 28% post-tax rate — a structural tax advantage that's central to KiwiSaver's after-tax return.

It depends entirely on whether the PIE is locked-in. IRD's own example: Ruby receives Best Start payments and holds a PIE term deposit — because those funds become accessible once the term ends, it's a NON-locked-in PIE, and Ruby needs to include that income through myIR's "Adjust your income" service or an IR215 form so it counts toward her Working for Families entitlement. Contrast that with a locked-in PIE like KiwiSaver: its investment income (as opposed to your own contributions or withdrawals) has no effect on Working for Families or student loan repayment income at all — it stays out of both calculations. If the PIE income already appears elsewhere in your assessment (for example, you've already declared it), don't add it again through Adjust your income — that would double-count it. When in doubt whether a specific PIE product is locked-in, check with the provider or IRD before filing.

Since 1 April 2020, IRD runs a separate PIE calculation using your CORRECT PIR as part of your income tax assessment — not your marginal rate. If your notified PIR was too low, the difference between what your PIE actually deducted and what your correct PIR would have deducted is added to your tax to pay; if it was too high, the difference is refunded (or offset against other tax owing). For example: $10,000 of attributed PIE income where your correct PIR is 17.5% but your PIE deducted tax at 10.5% — the rate difference is $700 ($1,750 owed minus $1,050 paid) added to your assessment, before any other adjustments, regardless of your salary's marginal rate. Either way, PIE income is reconciled against your correct PIR, not a marginal-rate top-up — but you avoid surprises by checking your PIR each April.

Some PIEs hold foreign assets and pass FIF tax up to PIR. Direct overseas investments above the $50,000 FIF threshold force FDR or CV calculations on your IR3. PIE wrapping simplifies admin and caps the rate at 28%, which is why platforms like Sharesies offer PIE versions of overseas exposures.
