The Foreign Investment Fund (FIF) rules are one of the most misunderstood parts of New Zealand tax. They tax New Zealand residents on certain overseas investments, such as shares in foreign companies and many global funds, in a special way that can tax you even when no dividend is paid. This guide explains why the rules exist, the threshold below which they do not apply, and the main methods for working out FIF income. It covers the concepts so you can recognise when the rules affect you; it is not tax advice.
New Zealand taxes residents on their worldwide income. Without special rules, you could hold foreign shares that grow strongly but pay tiny dividends, and pay almost no tax on that growth. The FIF rules counter this by deeming an income from such holdings, so foreign and domestic investments are taxed more comparably. That is the policy logic behind a regime that otherwise seems strange.
The rules do not apply to everyone. If the total original cost of all your attributing foreign investments is below a de minimis threshold, you are outside the FIF rules and simply pay tax on any actual dividends, like a domestic share. Crucially, the threshold is based on what you paid (your cost), not the current market value, so a portfolio that has grown can still be under the threshold.
Above the threshold, the most common method is the Fair Dividend Rate (FDR): your taxable FIF income is deemed to be a set percentage of the market value at the start of the tax year, regardless of whether the investment paid a dividend or rose in value. The comparative value (CV) method instead taxes the actual change in value over the year plus any distributions. Individuals can usually choose the lower of FDR and CV each year, which helps in a year where investments fell.
Under FDR you are taxed on a deemed percentage of your opening value, not on what you actually earned. In a strong year that can be less than your real gain; in a flat or down year it can be more, which is why individuals can switch to the comparative value method when it gives a lower result.
Not every foreign holding is caught. Certain Australian-listed shares are exempt, and the rules have particular treatment for different investment types. Many investors hold global shares through NZ-domiciled PIE funds, which handle the FIF calculations for you at your PIR. The rules are complex, so significant foreign portfolios usually warrant tax advice.
Reality: Above the threshold, FIF rules can tax a deemed income even when no dividend is paid. It is not just about cash received.
Reality: The de minimis threshold is based on the original cost of your foreign investments, not their current market value.
Reality: FDR taxes a deemed percentage of your opening value, regardless of actual gains or dividends. Comparative value taxes the actual change instead.
Reality: Some investments, notably certain Australian shares, are exempt, and holdings below the threshold are outside the rules.
Reality: Individuals can usually choose the lower of FDR and CV each year, which helps in a poor year for the investments.
Reality: Many ordinary investors with global shares or ETFs cross the threshold. Often a PIE fund handles it, but direct holders may need to apply the rules themselves.
Work out the total cost of your foreign investments to see if you are over the threshold. If you are, understand whether a PIE fund is handling FIF for you or whether you must apply FDR or CV yourself, and get advice for a sizeable portfolio. Knowing your position avoids a nasty surprise at tax time.
