PIR rate guide
Understanding the New Zealand PIR system.
10.5% PIR
Taxable income ≤ $14,000 AND total income ≤ $48,000
17.5% PIR
Taxable income ≤ $48,000 AND total income ≤ $70,000
28% PIR
Taxable income > $48,000 OR total income > $70,000
Important notes
- Use income from either of the last two tax years
- Choose the year that gives you the lowest PIR
- Total income = taxable income + PIE income
- You can elect a higher PIR but not a lower one
- Notify your fund provider if your rate changes
What is PIR?
PIR (Prescribed Investor Rate) is the tax rate applied to your Portfolio Investment Entity (PIE) investments, including KiwiSaver funds. Your PIR is based on your taxable income and PIE income from the previous two tax years.
Key benefits of PIE taxation
- PIR rates are generally lower than personal income tax rates
- No need to declare PIE income in your tax return (if using the correct PIR)
- Tax is automatically deducted at source
- Helps maximise your investment returns
Important: Using the wrong (higher) PIR means you overpay tax — and you cannot claim a refund for PIE income. Always use the lowest rate you qualify for.
