New Zealand FIF Tax

FIF Tax, Explained for Kiwis with Overseas Shares

Work out whether the rules may apply, understand the main methods, and estimate FDR/CV outcomes in plain English.

If you're a New Zealand tax resident with overseas shares, ETFs, or foreign unit trusts, you may need to deal with the Foreign Investment Fund (FIF) rules. The official guidance is detailed, but it can be hard to turn into a practical checklist.

FIFtax covers the questions investors usually need to answer first: whether the rules may apply, how the FDR and CV methods work, what records matter, and where the calculator can help. It is a guide and estimation tool, not a substitute for advice on your own tax return.
