Executive Summary
Are RSUs taxed at vest in New Zealand?
Typically yes for NZ employment: RSU-like benefits are included in taxable income when shares are received or forfeiture ends—subject to PAYE withholding and employer scheme rules.
What is FIF and why does it matter for RSUs?
Foreign Investment Fund rules can attribute income to NZ tax residents holding certain offshore interests—separate from employment tax on vesting. Thresholds, exemptions, and calculation methods differ. Consult an NZ tax advisor for your portfolio.
Do US citizens in Auckland file US returns?
US citizens remain taxable on worldwide income and may claim foreign tax credits for NZ tax paid—subject to limitations.
Auckland and Wellington support strong SaaS and fintech sectors with US listed equity.
Use relocating with equity, Australia ESS for Trans-Tasman context, ISO vs NSO.
The bottom line: Model PAYE on vest and FIF on holdings — two different questions.
Critical Warning: FIF rules are not intuitive for first-time US holders of offshore ETFs — get professional help if you hold broad portfolios.
Employment Income vs FIF
| Layer | Question |
|---|---|
| Vest | Salary tax via PAYE |
| Ongoing holdings | FIF attribution — if applicable |
Trans-Tasman Mobility
Australia vs NZ residency — see Australia guide for comparison.
US Tax Coordination
AMT, Form 1116.
Narrative: The Double Stack (PAYE + FIF)
An employee might pay PAYE on RSU vest, then hold US listed shares that fall under FIF methods in later years. This feels like double counting — it is not the same economic tax twice, but two different statutory regimes. Your advisor should map cost basis and FIF methods together.
Practical Checklist
- ☐ IRD summary vs broker
- ☐ FIF worksheet if offshore holdings
- ☐ FX NZD documentation
Common Mistakes
- Ignoring FIF after vest because PAYE felt final.
- Assuming Australia ESS rules match NZ exactly.
- Skipping US PFIC analysis for non-US funds.
