About FIFtax
We built FIFtax because the Foreign Investment Fund (FIF) rules are hard to understand when you are trying to manage a real portfolio, not read tax law for its own sake. We had to work through FIF calculations ourselves and found the process far more difficult than it should be, which was a big part of the motivation for building this site and the calculator.
The site explains the common rules in plain English, points back to Inland Revenue guidance, and provides calculators for common ordinary-share scenarios. The goal is to help you ask better questions, keep better records, and understand what may need to go into your tax return.
This is an independent information resource. We aim to keep it accurate and readable, but the information is general and may not fit every investor's situation.
Who runs FIFtax
FIFtax is owned and operated by Enoki Limited, a privately funded New Zealand limited-liability company.
How we keep the site useful
We link back to source material
Pages are written from public Inland Revenue guidance, especially IR461, and include links to official guidance where the full rule matters.
We keep calculators explainable
The calculators are designed for common ordinary-share workflows. They show assumptions and warnings so you can review the result instead of treating it as a black box.
We draw a clear advice boundary
FIFtax does not provide personal tax, legal, investment, or financial advice. If your facts are unusual, use the site to prepare better questions for IRD or a qualified adviser.
Please note: We cannot provide any personal financial or tax advice. If you have questions about your specific investment situation or tax obligations, please consult a qualified tax professional or contact Inland Revenue (IRD) directly.
