Foreign Investment Fund (FIF) — the basics.

The NZ regime for taxing foreign equity holdings — including SPY, VOO, QQQ and other US-listed ETFs Kiwis hold via Hatch, Stake, Sharesies or Interactive Brokers. Kicks in at NZ$50,000 cost base; calculation method matters more than most people realise.

What is FIF?

FIF is shorthand for the NZ Foreign Investment Fund regime. Its purpose: stop NZ residents from indefinitely deferring tax by holding income-producing assets offshore. Instead of waiting for the foreign asset to actually pay you a dividend, FIF deems an annual taxable income — calculated under one of five methods[1][2].

For ETF investors specifically, the practical reality is simpler than the legislation suggests. Most NZ retail investors holding US-listed ETFs use the FDR (Fair Dividend Rate) method, which deems 5% of the opening market value as taxable income, regardless of actual dividends or capital gains.

When FIF applies

The NZ$50,000 threshold

FIF applies to NZ-tax-resident individuals once the total cost base of qualifying foreign investments exceeds NZ$50,000 at any point during the tax year[2].

  • Cost base means what you paid, in NZD, at the time of purchase — not the current market value.
  • The threshold is per individual, not per couple. Joint accounts can split the cost base — see de minimis explained.
  • NZ-domiciled PIE funds (Smartshares, Kernel) are excluded from the FIF cost base, even if they hold US shares internally.
  • ASX-listed Australian-resident-listed companies are exempt under the Australian-shares carve-out.

FIF calculation methods

Five methods · two that matter for ETF holders

IRD lists five FIF methods[1]: Fair Dividend Rate (FDR), Comparative Value (CV), Cost, Deemed Rate of Return, and Attributable FIF Income. For an individual NZ retail ETF investor, only two are practically available — FDR (the default) and CV (an annual election that can be cheaper in down years).

Compare the two side-by-side at FDR vs Comparative Value — the choice can swing your tax bill several thousand dollars in a flat or negative year.

FAQ

Do I have to file FIF income on my IR3?⌄

If your foreign-investment cost base is over NZ$50,000 and none of the FIF exemptions apply, yes — FIF income goes on your IR3 individual return. The amount is calculated under one of the FIF methods (most NZ retail investors use FDR). If you are under NZ$50,000 the de minimis exemption applies and you instead declare actual dividends received.

Does FIF only apply to ETFs?⌄

No. FIF applies to most foreign equity holdings — direct US shares, foreign-domiciled mutual funds, foreign ETFs (SPY / VOO / QQQ etc.), and many foreign superannuation schemes. NZ-domiciled PIE funds are explicitly excluded. ASX-listed Australian shares have a separate exemption for Australian-resident-listed companies.

How do I find the cost base of my foreign investments?⌄

Cost base is what you paid (in NZD at the time of purchase), plus brokerage and FX cost. Most NZ-investor platforms (Hatch, Stake, Sharesies, Interactive Brokers) provide an annual tax report that consolidates this. Cross-check with your own purchase records — platform reports occasionally miss off-platform transfers in.
