Whether you are working for an overseas company, hold international investments, or have assets abroad, the New Zealand tax system—and your obligations to the IRD—can get complicated quickly. This calculator helps you estimate your potential NZ tax liability and foreign tax credits so you can plan your finances with more confidence.

How to Use This Calculator
Getting an estimate only takes a few seconds. Follow these steps:
- Set Your Residency: Choose your status (Standard Resident, Transitional Resident, or Non-Resident). This is the biggest factor in how the IRD views your foreign income.
- Input Domestic Income: Enter your current NZ-based income. This is necessary because tax in NZ is cumulative; adding foreign income can push you into a higher tax bracket.
- Employment & Passive Income: Input any gross income earned from overseas. If you paid tax in that foreign country, enter that amount in the “Foreign Tax Paid” box so the calculator can apply your Foreign Tax Credit (FTC).
- Portfolio Check: If your overseas portfolio exceeds $100,000 NZD, pay attention to the warning regarding FIF (Foreign Investment Fund) rules.
Frequently Asked Questions (FAQ)
What is the difference between a Standard and Transitional Resident? Transitional residents are generally exempt from paying tax on most foreign-sourced income for their first 48 months in New Zealand. If you are new to the country, this status can significantly lower your immediate tax burden.
How do Foreign Tax Credits (FTC) work? The goal of the FTC is to prevent “double taxation.” If you have already paid tax on money earned in another country, the IRD generally allows you to credit that against the tax you owe in NZ. Our calculator accounts for this to ensure you aren’t over-estimating your liability.
What are the FIF (Foreign Investment Fund) rules? If you hold overseas investments (shares, etc.) exceeding $100,000 NZD at any point in the income year, you likely fall under FIF rules. This means you are taxed on deemed income from those investments, regardless of whether you actually withdrew the money or sold the assets.
