PIE vs FIF — which structure applies to your ETF?
The single most consequential tax decision a Kiwi ETF investor makes. NZX-listed Smartshares and Kernel funds are PIE; US-listed SPY / VOO / IVV are FIF (above NZ$50,000). Different rules, different rates, often different bills.
In one paragraph
A PIE (Portfolio Investment Entity) is a NZ-domiciled fund that calculates and pays your tax for you, capped at your Prescribed Investor Rate — at most 28%, regardless of your marginal income tax rate[1][2]. FIF (Foreign Investment Fund) is the regime for foreign-domiciled holdings — including US-listed ETFs — once your total foreign-investment cost base crosses NZ$50,000. You self-calculate FIF income and add it to your IR3 at your marginal rate (up to 39%)[3].
Worked example
NZ$100,000 in S&P 500 exposure, two wrappers
Same underlying index, same NZ$100,000 portfolio value at the start of the year. Investor on the 39% marginal rate (high-income earner). Assumed 7% gross return; figures rounded.
| Item | USF (NZX-listed PIE) | VOO (US-listed FIF) |
|---|---|---|
| Wrapper | Smartshares US 500 (PIE) | Vanguard S&P 500 (FIF) |
| TER | 0.34% | 0.03% |
| Taxable income | PIR-based | FDR: 5% × NZ$100k = NZ$5,000 |
| Tax rate applied | 28% PIR cap | 39% marginal |
| Annual tax bill (illustrative) | ~NZ$1,400 | ~NZ$1,950 |
| Annual fee drag (TER × NZ$100k) | NZ$340 | NZ$30 |
| Total annual cost | ~NZ$1,740 | ~NZ$1,980 |
Net of tax + fees, the PIE wrapper is roughly NZ$240/year cheaper for this investor. Below the 39% marginal rate the gap narrows; at the 17.5% PIR / 17.5% marginal rate it can flip the other way. The point: don't choose by TER alone — model your own marginal rate. Past performance is not indicative of future results; this is an arithmetic illustration based on the stated assumptions.
When PIE wins · when FIF wins
Quick rules of thumb
- PIE often wins for investors above the FIF threshold AND on the 33% or 39% marginal rate (the 28% PIR cap is the big lever).
- FIF can be cheaper for investors below the NZ$50,000 threshold (de minimis applies — pay tax on actual dividends only) or on the 10.5% / 17.5% PIR.
- Always check your PIR at the start of every tax year — the wrong rate triggers a square-up either way[2].
- FX adds noise. US-listed FIF holdings are denominated in USD; the NZD value of FDR income depends on the spot rate at the start of the tax year.

FAQ
Are all NZX-listed ETFs PIE funds?⌄
In practice, yes — every Smartshares and Kernel fund listed on the NZX is structured as a NZ Portfolio Investment Entity. That includes DIV, FNZ, NZ20, USF and the rest of the 21-fund range we cover at /nz-etfs/. Always verify on the issuer fact sheet for the specific fund you are buying.
Can the same underlying index be PIE OR FIF?⌄
Yes. The S&P 500 index is tracked by both the US-listed Vanguard VOO (FIF for NZ residents above the NZ$50,000 threshold) and the NZX-listed Smartshares US 500 (USF, a PIE fund). Same exposure, different tax wrapper.
If I am under the NZ$50,000 FIF threshold, does PIE still beat FIF?⌄
Not always. Under de minimis you only pay tax on actual dividends received, at your marginal rate. For low-yield accumulating funds that may be lower than 28% PIR. The PIE advantage compounds above the threshold and at the 33% / 39% marginal rates.
