Foreign Investment Fund (FIF) rules apply to New Zealand tax residents who hold investments in offshore companies and funds. The Fair Dividend Rate (FDR) method is the most common way to calculate tax on these foreign investments. Understanding FIF and FDR matters if you hold overseas shares, international mutual funds, or ETFs based outside New Zealand - even if you haven't sold them or received actual dividends.
Foreign Investment Fund (FIF) rules are New Zealand's system for taxing offshore investments. Designed to prevent tax avoidance through accumulating wealth overseas without paying NZ tax.
| Investment Type | FIF Treatment | Notes |
|---|---|---|
| Foreign company shares | Subject to FIF | US, European, Asian stocks held directly |
| Offshore mutual funds/ETFs | Subject to FIF | Even if NZ-listed (e.g., Smartshares US500 fund) |
| Australian shares | Generally exempt | Trans-Tasman agreement - treated like NZ shares |
| NZ company shares | Not FIF | Taxed under normal NZ rules (dividends) |
| Under $50k total foreign investments | Exempt from FIF | De minimis exemption threshold |
Fair Dividend Rate (FDR) is the most commonly used calculation method for FIF income. It assumes your foreign investments returned 5% annually and taxes you on that deemed income.
Opening balance 1 April: $100,000 in US shares. FDR income: $100,000 × 5% = $5,000. This $5,000 added to your income and taxed at your marginal rate. If 33% tax rate: $5,000 × 0.33 = $1,650 tax owed. Applies even if shares fell in value or paid no dividends.
FDR taxes you on deemed income (assumed 5% return) not actual income. This creates situations where tax obligations don't match economic reality.
| Actual Performance | FDR Income Taxed | Result |
|---|---|---|
| Investment up 10% | 5% of opening value | Tax less than actual gain - favorable |
| Investment up 3% | 5% of opening value | Tax more than actual gain - unfavorable |
| Investment flat (0%) | 5% of opening value | Tax on non-existent gain - unfavorable |
| Investment down 5% | 5% of opening value | Tax despite actual loss - very unfavorable |
The paradox: You can owe tax on foreign investments that lost money. Conversely, if investments performed very well (15% gain), you're only taxed on deemed 5% return - favorable in that scenario.
If you hold multiple FIF investments (different funds, different countries), calculate FDR on combined total opening value, or can calculate separately for each and sum FDR income amounts.
FDR isn't the only method - alternatives exist but rarely used due to complexity.
Why FDR dominates: Simplicity. Opening value × 5% is straightforward. Other methods require complex calculations tracking cost base, currency movements, etc. For most investors, FDR is easiest despite occasionally unfavorable results.
If total cost of all foreign investments (excluding Australian shares) is under $50,000, you're exempt from FIF rules entirely.
| Scenario | FIF Treatment |
|---|---|
| Foreign investments total cost $40,000 | Exempt - no FIF calculations needed |
| Foreign investments total cost $60,000 | FIF rules apply to all investments |
| Breach $50k during year | FIF applies from when threshold breached |
| Australian shares $100k + other foreign $40k | Exempt - Australian shares don't count toward threshold |
Important: Threshold based on cost (what you paid), not current market value. Once you breach $50k, FIF applies even if value later falls below.
Australian shares get special treatment due to trans-Tasman tax agreement.
Buying shares in foreign companies directly - clearly subject to FIF if over threshold.
Investing through funds domiciled overseas - also subject to FIF. This catches many investors who don't realize: NZ-listed fund tracking US market (like Smartshares US500) is FIF because underlying fund is offshore.
NZ-domiciled Portfolio Investment Entities (PIE) are NOT subject to FIF for investors, even if PIE invests in foreign assets. PIE handles FIF at fund level. This is major advantage of PIE funds - individual investors don't deal with FIF complexity.
FIF income must be included in annual tax return (IR3). Section specifically for FIF income where you report calculated FDR amount.
If close to threshold, might strategically keep foreign investments below $50k to avoid FIF complexity. Limits offshore diversification but eliminates FIF admin burden.
Australian shares exempt from FIF and don't count toward threshold. Can hold significant Australian exposure without FIF implications.
NZ-domiciled PIE funds handle FIF at fund level. You pay tax through PIR (prescribed investor rate) on fund returns, but don't do FIF calculations yourself. Simpler for individual investors even if end result similar.
If near threshold, timing of new purchases relative to 1 April matters. Purchasing just after 1 April means not included in that year's opening balance calculation.
FIF rules are complex. If you have substantial offshore investments, professional tax advice recommended.
Final insight: FIF and FDR rules ensure NZ tax residents pay tax on offshore investment returns, even if returns aren't realized or distributed. FDR method's 5% deemed income simplifies calculations but can result in tax on losses or underreporting of large gains. Under $50k threshold exempts small investors. Australian shares get favorable treatment. PIE funds eliminate individual FIF calculations. If holding significant offshore investments, understand FIF implications and consider professional advice to ensure compliance and optimize tax position.
