Tax Residency in New Zealand
The 183-Day Rule
Spending more than 183 days in New Zealand during any 12-month period makes you a New Zealand tax resident, backdated to the first of those days.
The days do not need to be consecutive, and part-days, including your arrival and departure days, count as full days.
The Permanent Place of Abode Test
You can also become a tax resident without spending 183 days in the country if you have a permanent place of abode there, a home you have an enduring right to occupy, considered alongside your family, social, and economic ties to New Zealand.
Renting counts, as does a family home you can return to.
Getting an IRD number is required on arrival, needed for banking, work, and most financial transactions. Skip it, and employers withhold tax at the 45% no-notification rate. It alone doesn’t make you a tax resident, but it’s one of the first ties Inland Revenue checks.
To stop being a New Zealand tax resident, you generally need to be absent from New Zealand for more than 325 days in a 12-month period and give up any permanent place of abode there.
The Visa You Arrived on Matters Less Than You Think
New Zealand does not offer a dedicated passive-income or digital nomad visa the way some countries do. Americans most commonly arrive on:
Skilled Migrant Category Resident Visa, for points-based skilled workers
Essential Skills or Accredited Employer Work Visa, tied to a specific job offer
Active Investor Plus Visa, New Zealand’s investor route, opened in 2022 with tiers based on investment amount
Partnership or Parent Category Visa, for family reunification
The visa type does not determine your tax residency. Your physical presence and housing situation do. Most work visa holders become New Zealand tax residents within their first year.
New Zealand Income Tax Rates (2025-26 Tax Year)
New Zealand’s tax year runs from 1 April to 31 March, not the calendar year.
For the 2025-26 tax year (1 April 2025 to 31 March 2026), income tax uses five progressive brackets with no tax-free threshold, meaning tax applies from the first dollar earned.
| Taxable Income (NZD) | Rate |
| $0 - $15,600 | 10.5% |
| $15,600 - $53,500 | 17.5% |
| $53,500 - $78,100 | 30% |
| $78,100 - $180,000 | 33% |
| Over $180,000 | 39% |
Other New Zealand Taxes Americans Should Know
Capital gains: New Zealand has no general capital gains tax. The main exception is the bright-line rule, which taxes profit on residential property sold within 2 years of purchase (for property sold on or after 1 July 2024) at your marginal income tax rate. Your main home is generally excluded.
GST: New Zealand’s goods and services tax is 15%, applied to most goods and services. Businesses must register once turnover exceeds $60,000 in any 12-month period.
ACC earner’s levy: A separate 1.67% levy funds New Zealand’s no-fault accident compensation scheme and is deducted alongside PAYE, capped at an annual earnings threshold.
KiwiSaver: Employees are auto-enrolled unless they opt out within the first weeks of employment, contributing 3% to 10% of gross pay, matched by a minimum employer contribution.

New Zealand’s Transitional Resident Exemption: Your 4-Year Tax Window
Unlike Portugal’s NHR regime or similar programs that have closed to new arrivals, New Zealand’s transitional resident exemption remains open, automatic, and available to nearly every qualifying new migrant, including most Americans.
How the Exemption Works
Once you become a New Zealand tax resident for the first time (or return after at least 10 years away), most types of foreign income, including foreign dividends, interest, rental income, and overseas capital gains, are exempt from New Zealand tax for approximately 4 years.
The exemption period runs from your residency start date and ends 4 years after the end of the month in which you qualified. It applies automatically; you do not need to apply for it.
Who Qualifies
You have not been a New Zealand tax resident at any point in the previous 10 years
You can only use the exemption once in your lifetime
Employment or business income earned by working in New Zealand is not covered; the exemption applies to passive and foreign-sourced income
You can opt out if it works against you, for example if you want to claim Working for Families tax credits
What This Means for Your US Taxes
This is where the exemption gets complicated on the US side.
If your foreign income is exempt from New Zealand tax during this window, there is no New Zealand tax to credit against your US liability using the Foreign Tax Credit.
For many new arrivals with US investment income, the Foreign Earned Income Exclusion, or careful use of the exemption’s opt-out provision, can matter more during these 4 years than it will afterward.
Once the exemption ends and standard New Zealand rates apply to worldwide income, the Foreign Tax Credit typically becomes the stronger tool again.
Avoiding Double Taxation: FTC vs. FEIE
Americans living in New Zealand have two main tools to prevent the IRS from taxing income New Zealand already taxed.
Which one works best depends heavily on your income level, since New Zealand’s bottom two brackets (10.5% and 17.5%) sit well below equivalent US rates, while the top brackets (33% and 39%) generally exceed them.
| Foreign Tax Credit | Foreign Earned Income Exclusion | |
| IRS Form | Form 1116 | Form 2555 |
| Best suited for | Mid-to-high earners paying NZ's 30%-39% brackets | Lower earners, contractors, and those inside the transitional resident exemption |
| Reduces | US tax, dollar for dollar | Taxable foreign earned income (up to $130,000 for 2025) |
| Effect on SE tax | No effect on self-employment tax | No effect on self-employment tax either |
| Unused amounts | Can carry forward up to 10 years | Does not carry forward |
| Watch out for | Requires NZ tax actually paid on the income | Reduces AGI, which can affect the Child Tax Credit and IRA eligibility |
The Foreign Tax Credit (FTC): Best for Mid-to-High Earners
The Foreign Tax Credit (Form 1116) lets you apply New Zealand taxes paid against your US tax liability on the same income, dollar for dollar.
Example: An employee in Auckland earning $110,000 NZD (approximately $65,000 USD) pays roughly $23,700 NZD in New Zealand income tax. US federal tax on the equivalent income would be lower, so the FTC typically eliminates the US liability entirely and carries unused credit forward for up to 10 years.
The Foreign Earned Income Exclusion (FEIE): Useful for Lower Earners and the Self-Employed
The FEIE (Form 2555) allows qualifying Americans to exclude up to $130,000 (2025) of foreign earned income from US taxation.
Because New Zealand’s lower tax brackets can sit below comparable US rates, and because there is no totalization agreement to offset US self-employment tax, the FEIE is worth serious consideration for lower-income earners, contractors, and the newly arrived still inside their transitional resident exemption.
The tradeoff: FEIE reduces Adjusted Gross Income, which can affect eligibility for the refundable Additional Child Tax Credit and IRA contributions.
Not Sure Whether to Use the FTC or the FEIE?
New Zealand’s tax brackets cross above and below US rates depending on income, so the wrong choice can cost thousands. Let us help.
The US-New Zealand Tax Treaty
The United States and New Zealand have had a tax treaty in force since 1983, updated by a protocol that entered into force in 2010. It allocates taxing rights between the two countries on income types including business profits, dividends, interest, and pensions.
The Saving Clause Still Applies
Like nearly every US tax treaty, the US-New Zealand treaty includes a saving clause that allows the United States to tax its citizens as though the treaty did not exist. For most working Americans in New Zealand, this means the treaty does not eliminate your US filing obligation or automatically exempt your income from US tax.
Where the Treaty Still Helps
Treaty positions remain useful in specific situations, particularly around pension income and avoiding discriminatory taxation. Claiming a treaty position requires disclosure on Form 8833.
Tax Deadlines: New Zealand and the US
New Zealand Tax Deadlines
| Date | What Happens |
| 1 April | New tax year begins (runs to 31 March the following year) |
| April - June | Inland Revenue pre-populates income tax assessments for most PAYE-only taxpayers |
| 7 July | Standard deadline to file an Individual Income Tax Return (IR3), if required |
| 31 March (following year) | Extended deadline available automatically if you file through a registered tax agent |
US Tax Deadlines for Expats in New Zealand
| Date | What It Covers |
| April 15 | Standard filing deadline; unpaid tax begins accruing interest from this date |
| June 15 | Automatic 2-month extension for Americans living abroad, no form required |
| October 15 | Final extended deadline for taxpayers who filed Form 4868 |
| December 15 | Additional discretionary extension, subject to IRS approval |
Reporting Your New Zealand Bank Accounts to the US Government
Opening a bank account is one of the first things Americans do after arriving in New Zealand, and it is also one of the first things that creates a US reporting obligation.
FBAR (FinCEN Form 114)
If the combined value of all your foreign financial accounts exceeds $10,000 at any point during the calendar year, you must file an FBAR.
Combined means every account added together: checking, savings, KiwiSaver, and any other financial account held outside the US.
The FBAR is filed separately from your tax return, directly with FinCEN, electronically, due April 15 with an automatic extension to October 15.
Penalties for willful failure to file can reach the greater of $100,000 or 50% of the account balance per violation. Even non-willful failures carry penalties of up to $10,000 per account per year.
FATCA (Form 8938)
FATCA captures a broader set of foreign assets than the FBAR, including KiwiSaver, foreign pensions, and equity in foreign companies. Thresholds for Americans living abroad are higher than for US residents:
- Single filers: over $200,000 at year-end, or over $300,000 at any point during the year
- Married filing jointly: over $400,000 at year-end, or over $600,000 at any point
Form 8938 is filed with your annual Form 1040, not separately. FBAR and FATCA overlap in some areas but capture different things, and both may be required.
KiwiSaver, PIE Funds, and the PFIC Problem
This is one of the costliest traps for Americans living in New Zealand who do not know what to watch for.
KiwiSaver is structured in New Zealand as a Portfolio Investment Entity (PIE), taxed at a Prescribed Investor Rate (PIR) capped at 28%, even for members in the 33% or 39% personal tax bracket. On the US side, the picture is very different.
Most KiwiSaver funds hold underlying mutual funds or managed investments that meet the definition of a Passive Foreign Investment Company (PFIC) under US tax law.
Separately, depending on how contributions are structured, KiwiSaver can also be treated as a foreign trust, requiring Form 3520 and, in some cases, Form 3520-A.
A limited IRS relief procedure (Rev. Proc. 2020-17) exempts some tax-favored foreign retirement plans from Form 3520 and 3520-A. KiwiSaver generally does not qualify for that relief, so most KiwiSaver holders still face the full reporting picture. Do not assume your KiwiSaver is exempt without professional review.
How US Reporting Breaks Down
| Form | What It Covers | When It Applies |
| Form 8621 | PFIC reporting for underlying KiwiSaver or PIE fund investments | Generally, each year the fund is held; narrow exceptions exist |
| Form 3520 / 3520-A | Foreign trust reporting for the KiwiSaver structure itself | Depends on whether employee or employer contributions are larger |
| FBAR | KiwiSaver balance counted toward the $10,000 aggregate threshold | Every year the threshold is met |
| Form 8938 | KiwiSaver counted toward FATCA specified asset thresholds | When total foreign assets exceed the threshold |

New Zealand Retirement Accounts
Retirement income for Americans in New Zealand typically comes from three sources, each taxed differently in each country:
| Income Source | Taxed in New Zealand? | Taxed in the US? |
| NZ Superannuation (NZ Super) | Yes, as ordinary income | Yes, generally as foreign pension income |
| KiwiSaver withdrawals | Yes, depending on scheme and age | Yes; may also carry PFIC and foreign trust history |
| US Social Security | Yes, under NZ tax law | Up to 85% may be taxable depending on total income |
New Zealand Superannuation (NZ Super)
NZ Super is a universal government pension paid to qualifying New Zealand residents from age 65, largely independent of prior earnings or contributions. It is taxable in New Zealand as income and, because it is a government-paid benefit, has historically interacted with certain US Social Security offset rules.
US Social Security While Living in New Zealand
US Social Security benefits received by New Zealand residents are generally taxable in New Zealand under local tax law, and up to 85% may also be taxable on your US return depending on total income.
The Social Security Fairness Act Changed the Math
For anyone receiving both NZ Super and US Social Security, a major US law change matters here. The Social Security Fairness Act, signed January 5, 2025, repealed the Windfall Elimination Provision (WEP) and Government Pension Offset (GPO), effective for benefits payable from January 2024 onward.
Those provisions previously reduced US Social Security benefits for people also receiving a pension from work not covered by US Social Security, which could include NZ Super.
If your US Social Security was ever reduced because of NZ Super, you may be owed a retroactive adjustment. The repeal does not make Social Security tax-free, and it does not create a totalization agreement where none exists, but it removes a penalty that used to apply directly to this exact situation.
Retiring in New Zealand?
NZ Super, KiwiSaver, and US Social Security interact in unexpected ways, and the WEP/GPO repeal has changed the math. We help Americans retiring to New Zealand get this right from year one.
No Totalization Agreement
A totalization agreement is a treaty that normally stops Americans working abroad from paying into two countries’ social security systems on the same income, letting them combine credits from both to qualify for benefits.
The US has about 30 such agreements, but not with New Zealand, and none is being negotiated. That’s the biggest structural difference between NZ and most other expat destinations.
W-2 employees of NZ employers are usually fine, since NZ employers don’t withhold US Social Security or Medicare.
But self-employed Americans and contractors can get hit twice: the IRS can still charge the full 15.3% self-employment tax on net earnings, on top of New Zealand’s ACC levy, with no agreement to prevent the overlap.
| Work Status | NZ Side | US Side |
| W-2 employee of a NZ employer | PAYE and ACC earner's levy withheld automatically | No US self-employment tax; income tax exposure handled via FTC or FEIE |
| Self-employed / contractor | Pays ACC earner's levy on net income | Full 15.3% US self-employment tax applies, with no offset from NZ contributions |
The FIF Regime: New Zealand’s Tax on Your US Investments
Here is a wrinkle most Portugal, Spain, or UK expat guides never mention, because it does not exist there. New Zealand taxes its own residents on offshore investments through the Foreign Investment Fund (FIF) rules, and that includes US brokerage accounts, US mutual funds, and other American holdings once you become a New Zealand tax resident.
How FIF Rules Work
If the total cost of your foreign shares, funds, and similar investments exceeds $50,000 NZD, New Zealand generally taxes you on deemed income from those holdings each year, regardless of whether you actually received a dividend or sold anything.
The two common calculation methods are the Fair Dividend Rate (FDR) method, which taxes 5% of the opening market value of your investments each year, and the Comparative Value (CV) method, which taxes the actual increase in value over the year. Most taxpayers use whichever produces the lower result, subject to Inland Revenue’s rules on which method applies to which assets.
What Typically Counts as a FIF Interest
US brokerage accounts holding individual shares or ETFs above the $50,000 threshold
US mutual funds and index funds held outside a retirement account
Foreign life insurance policies with an investment component
US retirement accounts such as 401(k)s and traditional or Roth IRAs are generally treated differently from ordinary FIF interests and taxed under New Zealand’s foreign superannuation rules instead, which use a separate schedule-based method when funds are withdrawn or transferred.
Get this analyzed before you touch a US retirement account after becoming a New Zealand tax resident.
Why This Matters Alongside US Rules
The FIF regime and the US PFIC regime were built independently, by two different countries, with no coordination between them.
It is entirely possible for the same US-based investment to be taxed on deemed income in New Zealand under FIF while also being subject to PFIC-style scrutiny if it happens to be a foreign fund from the US perspective, or to sit outside PFIC rules entirely if it is a straightforward US-domiciled holding.
Liquidating US investments simply to avoid FIF exposure can also trigger US capital gains tax you were not otherwise planning for.
This is a genuine two-country planning problem, not a one-sided compliance task, and it deserves review before you move, not after your first New Zealand tax return is due.
Business Ownership in New Zealand and IRS Compliance
The New Zealand Limited Company
A New Zealand Limited company is the standard private company structure, the rough equivalent of a US LLC taxed as a corporation.
Americans commonly set one up to run a business, freelance through, or hold investments, and registering one also generates an IRD number and, if turnover exceeds $60,000, a GST registration.
If you own 10% or more of a New Zealand Limited company, you are required to file Form 5471 annually with the IRS. The penalty for failure to file is $10,000 per form per year, even if the company made no money and you owe zero US tax.
GILTI and Retained Earnings
If your New Zealand company is a profitable service business, the IRS may require you to pay US tax on the company’s retained earnings each year under the GILTI (Global Intangible Low-Taxed Income) rules, even if the company never made a distribution to you.
A New Zealand Limited company does not shield its US-citizen owner from US tax the way a US LLC does. The structure matters, and the tax treatment is not automatic.
| IRS Requirement | Trigger | Penalty for Missing It |
| Form 5471 | Owning 10% or more of a NZ Limited company | $10,000 minimum per form, per year |
| GILTI inclusion | Profitable NZ company with retained earnings | US tax owed on retained earnings, even with no distribution |
American Business Owner in NZ?
Form 5471, GILTI, and self-employment tax can all apply, even without a distribution. We help American business owners in New Zealand stay compliant.
State Taxes: The Issue Americans Often Miss
Moving to New Zealand does not automatically end your US state tax obligations. Several states apply aggressive residency rules and may continue to tax your income after you move abroad if you retain meaningful ties: a bank account, a driver’s license, a storage unit, or family property.
| State | Why It's Aggressive |
| California | Presumes continued residency if ties like property, bank accounts, or a driver's license remain |
| New York | Applies a strict statutory residency test based on days present and a permanent place of abode |
| Virginia | Requires a clear, documented change of domicile before residency ends for tax purposes |
Behind on Your US Taxes? The IRS Streamlined Program Exists for This
If you have been living in New Zealand without filing US tax returns, you are not alone, and there is a legal, penalty-free path back into compliance.
The IRS Streamlined Foreign Offshore Procedures allow Americans living abroad who are behind on their US taxes to:
File three years of delinquent tax returns
File six years of delinquent FBARs
Pay any outstanding tax owed, plus a small interest charge
Have all penalties waived, provided the failure was non-willful
“Non-willful” means you were not intentionally hiding income from the IRS. Many Americans who moved abroad simply did not know they had to keep filing. That is exactly the population this program was designed for.
The critical deadline is not a calendar date; it is when the IRS contacts you first. Once the IRS initiates an examination or inquiry, the Streamlined program closes permanently for that taxpayer.
Universal Tax Professionals has a 100% success rate in Streamlined Filing Procedures, guiding Americans across New Zealand, Australia, and the Pacific through this process from first contact to final confirmation.
