PIE Tax Structure NZ: Complete Guide to Portfolio Investment Entities
A Portfolio Investment Entity (PIE) is a NZ fund structure that taxes investment income at your Prescribed Investor Rate (PIR), currently 0%–28%, instead of your personal marginal rate. For investors on the 39% tax bracket, PIE funds can save up to 11% on investment income.

How Much Can You Save with PIE Funds?
For high-income New Zealand investors, PIE funds provide significant tax advantages. Compare your tax on $100,000 of investment income:
| Your Marginal Rate | Tax on Non-PIE | Tax on PIE (28%) | Annual Savings |
|---|---|---|---|
| 39% (income >$180K) | $39,000 | $28,000 | $11,000 |
| 33% ($70K-$180K) | $33,000 | $28,000 | $5,000 |
| 30% ($48K-$70K) | $30,000 | $28,000 | $2,000 |
| 17.5% ($14K-$48K) | $17,500 | $17,500 | $0 |
💡 Key insight: If you're on the 39% tax bracket, every $1 million invested in PIE funds saves you approximately $11,000 per year in tax compared to non-PIE investments with the same return.
Prescribed Investor Rates (PIR) for 2025/26
Your PIR is determined by your income over the past two tax years. It's your responsibility to select the correct rate—using a rate that's too low can result in penalties.
| PIR | Taxable Income (last 2 years) | PIE Income + Taxable Income |
|---|---|---|
| 10.5% | $14,000 or less | $48,000 or less |
| 17.5% | $48,000 or less | $70,000 or less |
| 28% | All other NZ tax residents | |
Non-Resident Investors
Non-residents may have a PIR of 28% or different rates depending on their tax residence status and any applicable double tax agreements. Consult a tax adviser for your specific situation.
PIE vs Non-PIE Fund Comparison
| Feature | PIE Fund | Non-PIE (LP/Trust) |
|---|---|---|
| Maximum Tax Rate | 28% | 39% (your marginal rate) |
| Tax Filing | Not in tax return (fund pays) | Include in tax return |
| Loss Offset | Only within same PIE fund | Can offset other income |
| Capital Gains | Taxed within fund at PIR | Generally not taxed (on revenue account may be) |
| Best For | High-income investors, income funds | Capital growth strategies, PE/VC |
| Common Asset Classes | Private credit, bonds, income funds | Private equity, VC, property development |
| Student Loan Repayments | Not counted as income | Counted as income (affects repayments) |
Advantages of PIE Funds
Taxed at PIR (0%–28%)
Investment income is taxed within the fund at your Prescribed Investor Rate, which may be lower than your marginal tax rate.
No RWT for PIE Income
Resident Withholding Tax is handled inside the fund, simplifying your tax obligations and cash flow management.
Consolidated Reporting
Receive consolidated year-end reporting from the fund manager, reducing your administrative burden.
Who Can Use a PIE?
New Zealand Tax Residents
Most NZ tax residents can invest in PIE funds and benefit from PIR taxation.
Non-Residents
Non-residents may invest via certain PIE classes, but tax treatment varies. Professional advice is recommended.

- • 10.5% - Income ≤ $14,000 and taxable income ≤ $48,000
- • 17.5% - Income ≤ $48,000 and taxable income ≤ $70,000

Which Wholesale Funds Use PIE Structure?
Many income-generating wholesale funds use PIE structure to provide tax efficiency. Here's a breakdown by asset class:
✅ Commonly PIE Structure
- • Private Credit Funds - AAM, Pallas, NZ Private Credit
- • First Mortgage Funds - Norfolk, Southern Cross
- • Managed Equity Funds - Devon, Kernel, Milford
- • Bond Funds - Most fixed income funds
- • Income Funds - Diversified income portfolios
- • KiwiSaver - All KiwiSaver schemes
⚠️ Typically Non-PIE (LP/Trust)
- • Private Equity - Movac, Pioneer, Direct Capital
- • Venture Capital - GD1, Icehouse Ventures, 2040
- • Property Syndications - Quarry, Jasper, Augusta
- • Forestry - Forest Enterprises, PF Olsen
- • Agriculture - Dairy, horticulture partnerships
- • Development Projects - Single-asset SPVs
Why PE/VC Use Limited Partnerships
Private equity and venture capital funds typically use LP structures because: (1) capital gains on share sales are generally not taxed in NZ, unlike PIE income; (2) losses can flow through to investors for offset; and (3) the structure aligns with global PE/VC norms for co-investment with institutional investors.
Non-PIE Fund Structures Explained
Not all investment structures qualify as PIEs. Understanding alternatives helps you choose the right structure for your tax situation and investment goals:
Limited Partnerships (LP)
Tax treatment: "Look-through" structure where income/gains flow directly to your tax return at your marginal rate. Best for: Capital gains strategies (PE, VC, property development) where gains may be tax-free. Drawback: Income taxed at up to 39%.
Company Structures
Tax treatment: Company pays 28% tax, dividends may carry imputation credits.Best for: Reinvesting profits, family trusts, estate planning.Drawback: Double taxation if profits distributed without full imputation.
Unit Trusts
Tax treatment: Income flows through to unitholders at their marginal rates.Best for: Pooled investments without PIE election.Drawback: No tax cap—high earners pay full 39% on income.
Multi-Rate PIE (MRP)
Tax treatment: Each investor taxed at their individual PIR (10.5%, 17.5%, or 28%).Best for: Most retail and wholesale funds.Benefit: Tax paid within fund, no tax return filing for PIE income.
April 2025 Tax Changes: Why PIE Funds Matter More
Changes to New Zealand's tax thresholds from April 2025 have increased the tax advantage of PIE funds for high-income investors:
| Change | Before April 2025 | After April 2025 |
|---|---|---|
| Top marginal rate | 33% (over $70K) | 39% (over $180K) |
| PIR cap | 28% | 28% (unchanged) |
| Max PIE benefit | 5% tax saving | 11% tax saving |
Impact for Wholesale Investors
For investors earning over $180,000, the gap between their marginal rate (39%) and the PIE cap (28%) has increased from 5% to 11%. This makes PIE-structured income funds significantly more attractive than non-PIE alternatives for income-generating investments.
Example: A wholesale investor with $500K in a private credit fund earning 10% p.a. ($50K income) saves $5,500/year by using a PIE-structured fund vs. a non-PIE LP structure.
How PIE Tax Treatment Works
Tax Calculation
PIE funds calculate and pay tax on your investment income using your PIR, which you declare when investing. This happens automatically within the fund, so you don't need to calculate it yourself.
Example:
If you earn $10,000 in PIE income and your PIR is 17.5%, the fund withholds $1,750 in tax. You receive $8,250, with no additional tax obligations on that income.
Determining Your PIR
Your PIR is based on your taxable income from the previous two tax years. You must use the correct rate - using a rate that's too low can result in penalties.
- Review your income from the last two years before selecting your PIR
- Update your PIR if your income situation changes significantly
- Consult your accountant if you're unsure which rate to use
Distribution vs Accumulation
Some PIE funds distribute income (paying dividends/distributions to investors), while others accumulate income (reinvesting it within the fund). In both cases, tax is calculated and paid at your PIR rate.
Frequently Asked Questions
What is the difference between PIR and marginal tax rates?
PIR rates (10.5%, 17.5%, 28%) are often lower than marginal tax rates (10.5%, 17.5%, 30%, 33%, 39%). This can result in tax savings for higher-income earners investing in PIE funds.
Can I change my PIR during the year?
You can notify the fund manager to change your PIR, but it's important to ensure you're using the correct rate based on your income levels. Changes typically take effect for future periods.
Do I need to declare PIE income in my tax return?
PIE income is generally not included in your tax return as tax is paid within the fund. However, you should keep records and may need to declare for other purposes like student loan repayments or Working for Families.
Are PIE funds better than non-PIE investments?
It depends on your circumstances. PIE funds can offer tax efficiency and administrative simplicity. However, the right investment should be chosen based on your overall investment objectives, risk tolerance, and tax situation - not just the structure.
Can overseas investors use PIE funds?
Some PIE funds offer classes for non-resident investors, but tax treatment varies. Non-residents should seek professional tax advice before investing in PIE funds to understand the implications.
How do PIE losses work?
PIE tax losses cannot be offset against other income or carried forward to future years like regular tax losses. They can only be used to reduce future PIE income from the same fund.
