What you owe, and to whom
US tax-treaty status, residency triggers, and state-exit considerations.
New Zealand has a US income tax treaty but no totalization agreement — partial coverage. Tax residency triggers at 183 days of presence, after which NZ taxes worldwide income; the treaty and Foreign Tax Credit prevent most double taxation on income. Because there is no totalization agreement, self-employed Americans face 15.3% US self-employment tax on top of NZ contributions. US filing (including FBAR/FATCA) always remains.
Income Tax Treaty in Force
Treaty Protection ActiveThe US–New Zealand income tax treaty provides reduced withholding on dividends, interest, royalties, and pensions, and the Foreign Tax Credit prevents most double taxation on employment income.
No Totalization Agreement
Double SS Tax RiskNew Zealand has no Social Security totalization agreement with the US. Self-employed Americans owe 15.3% US self-employment tax on top of any NZ contributions — the FEIE does not cover self-employment tax.
Worldwide Tax System
183-Day TriggerNew Zealand taxes residents on worldwide income once you pass 183 days of presence. The treaty and FTC mechanism relieve most double taxation, but cross-border filing complexity is real.
US Filing Never Stops
FBAR / FATCAUS citizens file annually regardless of residence. NZ accounts over $10K trigger FBAR; FATCA reporting applies. The FEIE (~$126,500) and FTC are the primary relief mechanisms.
Americans should know
- You file US taxes regardless — New Zealand residency doesn't change that
- Passing 183 days of presence makes you an NZ tax resident on worldwide income
- No totalization: self-employed Americans owe 15.3% US SE tax on top of NZ contributions — the FEIE doesn't cover it
- NZ accounts over $10K trigger FBAR reporting; FATCA applies
