Thresholds

The $50,000 de minimis threshold, explained

Under NZ$50,000 of overseas shares, FIF rules may not apply. How the de minimis threshold is measured, and the traps that catch people out.

Updated 16 May 20264 min readEvery term explained

Before you wrestle with FDR or CV, there's one test that decides whether you need to deal with FIF tax at all: the de minimis threshold.

The rule in one sentence

If the total cost of all your attributing foreign shares stayed at or under NZ$50,000 at all times during the tax year, the FIF rules generally don't apply, and you simply return any actual dividends instead.

💡 Good to know: the test is on cost, not market value. It's what you paid for the shares (in NZD), not what they're worth now.

How the threshold is measured

A few details trip people up:

  • It's measured across the whole year, not just at year-end. If your cost base went over $50k at any point, even briefly, you can fall outside the exemption.
  • It's the combined cost of all your FIF holdings, not per-broker or per-share.
  • Cost is generally in New Zealand dollars, converted at the time you acquired each parcel.

The traps

  • A mid-year top-up that pushes your cumulative cost over $50k can pull you into the FIF rules for the whole year.
  • The threshold applies per person, so a couple holding shares jointly should check how their share of the cost is counted.
  • You can also elect into the FIF rules even under $50k, though most people won't want to.

What to do next

If you're confident you stayed under $50k all year, you likely don't need the FIF calculation: just return your dividends. If you went over, or you're not sure, work out your FIF income using the FDR and CV methods.

Key takeaways

  • Stay under NZ$50,000 total cost all year and the FIF rules generally don't apply.
  • The test is on cost in NZD, measured across the whole year, combined across holdings.
  • A mid-year top-up over the line can catch you for the entire year.
