If you own overseas shares, ETFs, or managed funds - even through Forsyth Barr, Craigs, or Sharesies - you might be liable for FIF (Foreign Investment Fund) tax. Here's what it means, what IRD looks for, and how to stay compliant.

FIF stands for Foreign Investment Fund. It's a tax regime used by Inland Revenue to capture income from overseas investments held by NZ tax residents. You may be subject to FIF tax if you've brought more than $50k NZD of:

How Is FIF Income Calculated?

*Disclaimer: This section is highly simplified, and there are other less common methods available that are not mentioned here. This article is an oversimplification with the aim of explaining the core of the FIF rules without getting bogged down by jargon

If your offshore investments cost more than NZD $50,000 for an individual ($100,000 for a joint holding), you must calculate your taxable FIF income. There are two main methods, and you can switch between them from year to year, but you must be consistent in using the same method for all your investments in a given year - you can't cherry pick one method for some investments and another method for others:

1. Fair Dividend Rate (FDR)

Example:
Opening market value = $200,000
FIF income = 5% of $200k = $10,000
Tax payable ≈ $3,300 (at 33%)

2. Comparative Value (CV)

Example:
Start value = $200,000
End value = $195,000
Dividends = $2,000
FIF income = ($195k + $2k) - $200k = –$3,000
No tax payable, but the loss is not carried forward to offset future income.

Common Mistakes

❌ Misreporting income from Vanguard Funds

→ These are foreign shares, even if bought in NZ dollars

❌ Not claiming the correct fees

→ Brokerage fees for buying and selling are typically not deductible for long-term investors, while portfolio management fees are

❌ Applying FIF rules on a portfolio costing < $50k

→ While you can elect into the FIF rules, you may not need to report FIF income at all if under the threshold (individuals only)

❌ Using a mix of FDR and CV methods

→ You must choose one method consistently for all relevant investments

Over or underclaiming overseas tax credits

Some distributions come with overseas tax credits attached. The extent to which you can claim these is on a case-by-case basis.
