Last updated: July 2026 Reviewed & verified by Galvin Mendonca

Definition

A collective investment fund taxed at the investor's PIR rate, capped at a maximum of 28%.

Key Takeaways

  • PIE funds (KiwiSaver, managed funds, unit trusts) receive favorable tax treatment in NZ.
  • Investment income taxed at investor's PIR (10.5%, 17.5%, 28%), not marginal tax rate (up to 39%).
  • PIE funds automatically calculate and deduct tax, so investors don't report PIE income in tax returns.
  • PIE structure can result in significant tax savings for higher-income earners.

Detailed Explanation

A Portfolio Investment Entity (PIE) is a special type of investment fund in New Zealand that receives favorable tax treatment. PIEs include KiwiSaver schemes, managed funds, unit trusts, and group investment funds. The key advantage of PIEs is that investment income (interest, dividends, capital gains) is taxed at the investor's Prescribed Investor Rate (PIR), which is capped at 28%, rather than at their marginal income tax rate (which can be as high as 39%).

PIE funds calculate and deduct tax on investment returns automatically at each investor's chosen PIR (10.5%, 17.5%, or 28%). This means investors don't need to report PIE income in their annual tax returns, simplifying compliance. PIE status also allows funds to distribute tax credits and avoid double taxation on NZ-sourced dividends.

Real-World Example If Emily invests $50,000 in a PIE fund and earns $3,000 in investment returns, the fund taxes this at her PIR of 17.5% ($525), not her marginal rate of 30% ($900). This PIE structure saves Emily $375 in taxes annually while simplifying her tax obligations.
