New Zealand FIF Tax for Advisers: the NZ$50,000 Test, Fair Dividend Rate and PIEs

Published 22 October 2026 by Borderfolio

A New Zealand tax resident who holds US-listed ETFs, Irish UCITS funds or most Australian ETFs is usually not taxed on the dividends and gains they actually receive. Above a threshold, those holdings fall under the foreign investment fund (FIF) rules, and the client is taxed on deemed income instead. For a client who has just moved to New Zealand, or whose offshore portfolio has grown, the rules change both the tax bill and the choice of fund. This note sets out how the rules work, with a worked example, and where a New Zealand PIE changes the answer. It is decision support for a professional conversation, not tax advice.

Who is in the FIF rules

The rules apply to New Zealand tax residents who are not transitional residents. A FIF interest is an interest in a foreign company or foreign unit trust, so US ETFs, Irish UCITS funds and most overseas shares qualify. Some holdings are outside the rules:

• New Zealand companies and New Zealand funds (PIEs) are not foreign, so they are never FIF interests.
• ASX-listed Australian companies are exempt if they are Australian resident, on the ASX official list and required to keep a franking account (s EX 31). IRD publishes a lookup tool for this.
• Australian unit trusts, which includes most ASX-listed ETFs, are exempt only if they meet every condition in s EX 32. These include an NZ resident withholding tax proxy and minimum turnover and distribution tests. Treat an Australian ETF as a FIF interest until the issuer confirms it qualifies.

The NZ$50,000 test is on cost, not value

For an individual, FIF income arises in a year when the total cost of their FIF interests is more than NZ$50,000 at any time in that year (s CQ 5(1)(d)). Three details matter in practice:

• Cost, not market value. A holding bought for NZ$45,000 and now worth NZ$100,000 is still under the threshold. Cost includes transaction fees and is converted to NZD.
• Over the threshold, everything is in. The first NZ$50,000 is not exempt. One purchase that takes the total cost over the line at any point in the year brings every FIF interest into the rules for that year.
• Opting in locks the client in. A client who returned FIF income while under the threshold in one of the previous four years stays in the rules (s CQ 5(1)(d)(iii)). Ask before assuming a small portfolio is outside them.

Below the threshold, dividends are taxed in the ordinary way at the client's marginal rate, with a credit for foreign withholding.

How FIF income is calculated

Most listed holdings use the fair dividend rate (FDR) method: FIF income is 5% of the market value of the holdings at the start of the income year, 1 April (s EX 52). The dividends actually received are not taxed separately, and no loss can arise. When a holding is bought and sold within the same year, a quick sale adjustment can add to the figure.

An individual may instead use the comparative value (CV) method in any year (s EX 51): closing value plus dividends and sale proceeds, less opening value and purchases. A loss under CV is reduced to zero for ordinary shares. The choice applies to all FDR-eligible holdings for the year. In a year when the portfolio falls, CV often gives nil FIF income where FDR would still give 5%.

FIF income is taxed at the client's marginal rate. From the 2026 income year these are 10.5%, 17.5%, 30%, 33% and 39%, with 39% applying above NZ$180,000.

Foreign tax credits are narrower than they look

A credit is allowed for foreign tax the client paid, limited to the lesser of the foreign tax and the NZ tax on that holding's FIF income (subpart LJ). Under the New Zealand–US treaty that means US withholding of up to 15%. Two cases catch clients out:

• No W-8BEN on file. The broker withholds 30%, but only 15% can be credited. The other 15% is a pure cost.
• Irish funds. An Irish UCITS fund suffers 15% on its US dividends inside the fund. That is the fund's tax, not the client's, so it gives no credit in New Zealand. The usual argument for Irish domicile does not carry over to a FIF investor.

A worked example

A New Zealand resident on a 33% marginal rate holds an S&P 500 ETF worth NZ$100,000 on 1 April. It cost NZ$80,000 and pays NZ$1,300 of dividends a year. Exchange rates, the quick sale adjustment and the CV method are left aside.

• US ETF. FIF income is 5% × 100,000 = 5,000. NZ tax at 33% is 1,650. The 195 of US withholding (15% of 1,300) is credited, so the client pays 1,455 in New Zealand and 195 in the US: 1,650 in total.
• Without a W-8BEN. 390 is withheld and only 195 is credited, so the total is 1,845.
• Irish fund. The 195 lost inside the fund cannot be credited, so the client pays the full 1,650 in New Zealand on top: 1,845.
• Listed PIE. The fund pays FDR tax at 28% on its own holdings (5,000 × 28% = 1,400) and credits the US withholding it suffers against that. Its distributions are excluded income for the client.

At 33% the PIE costs NZ$60 a year more than the US ETF, because its fee outweighs the lower tax rate. At 39%, the US ETF's tax rises to 1,950 and its total to 1,980, so the PIE costs NZ$240 a year less. At 30% and below, the US ETF stays cheaper. The answer depends on the client's rate and the fees, not on the structure alone.

Where a PIE changes the answer

A portfolio investment entity pays tax on its offshore holdings at fund level, usually under FDR, and credits the foreign tax it suffers there. Two kinds matter for this comparison:

• Listed PIEs, such as the Smart ETFs on the NZX, pay tax at 28%. Their distributions are excluded income unless the client chooses to include them in a return (s CX 56C). A client on a lower rate can include them to recover the difference.
• Unlisted multi-rate PIEs tax each investor at their prescribed investor rate (PIR): 10.5%, 17.5% or 28%, based on income in the two previous years. For a client on 33% or 39% the PIR is capped at 28%. That cap is the main tax advantage, before fees.

A PIE also takes the FIF administration off the client: no FIF disclosure and no annual choice between FDR and CV for those holdings. Against that, compare the fees, the tracking difference, and the cost of selling the existing holdings to switch.

What to settle with the client

• Are they an NZ tax resident, and are they still a transitional resident?
• What is the total NZD cost of their FIF interests, including holdings at other brokers and their share of joint holdings?
• Have they returned FIF income in any of the last four years?
• Which Australian holdings are companies, and which are unit trusts that need EX 32 confirmed?
• What is their marginal rate, and what PIR applies to them?
• Is a W-8BEN on file at every broker that holds US-domiciled funds?

How Borderfolio for Advisors handles it

• Classification per holding. NZ holdings are marked as not FIF interests, ASX companies as exempt under s EX 31, and Australian unit trusts as FIF interests until you mark them as meeting s EX 32.
• The threshold from cost. The cost test uses the cost basis from the client's confirmed statements, with switches for prior opt-in and transitional residence. If a cost is missing, the result says so rather than guessing.
• FDR, credit and total tax cost. Each holding shows FIF income, the credit capped at 15% and at the NZ tax, and the withholding lost inside Irish funds as a cost.
• The PIE comparison. S&P 500 and total-world funds are compared with Smart listed PIEs and with an unlisted PIE at the client's PIR, as tax and fees a year.
• In scenarios and reports. The estimate appears for NZ residents, and for a planned or what-if move to New Zealand. The report includes it as a finding with its sources.

The documentation shows the screen and lists every input.

Where the estimate stops

• FDR is estimated on today's value as a guide to the next income year. The CV method, the quick sale adjustment and the client's exchange-rate election are not calculated.
• Credits for withholding by countries other than the US are not applied.
• KiwiSaver balances and unlisted funds are recorded as other assets, not analysed.

Frequently asked questions

Is the NZ$50,000 FIF threshold based on cost or market value?

Cost. The test is whether the total cost of the person's FIF interests exceeded NZ$50,000 at any time in the income year. A portfolio worth more than NZ$50,000 can still be under the threshold if it cost less.

Are Australian shares and ETFs subject to the FIF rules?

ASX-listed Australian companies that keep a franking account are generally exempt. Australian unit trusts, which include most ASX ETFs, are exempt only if they meet the conditions in s EX 32. Otherwise they are FIF interests.

Can an investor choose between the FDR and CV methods?

An individual can choose each year, for all their FDR-eligible holdings together. FDR taxes 5% of the opening value. CV taxes the actual gain including dividends, and a loss is reduced to zero, so CV gives less in a year when the portfolio falls.

Is a New Zealand PIE always cheaper than an offshore ETF?

No. A PIE caps the tax rate at 28%, which helps clients on 33% or 39%, but local funds often charge more. In the worked example the PIE costs NZ$60 a year more at a 33% marginal rate and NZ$240 a year less at 39%.
