NZ Tax Resident With US Income: 7 Essential Tax & Foreign Tax Credit Rules

If you are a NZ tax resident with US income, understanding your tax obligations can be complicated. Income from US employment, dividends, interest, rental property or investments may need to be considered in both countries.

New Zealand generally taxes its tax residents on worldwide income, even when overseas income is not transferred to New Zealand and even when tax has already been deducted overseas.

At the same time, the United States has its own rules for US-source income and for people who remain US citizens or US tax residents.

This guide explains what a NZ tax resident with US income should know about overseas income reporting, the NZ–US Double Tax Agreement, foreign tax credits, US tax withholding and common reporting mistakes.

Important: International tax depends on your individual circumstances. This article provides general information and is not personalised New Zealand or US tax advice.

NZ Tax Resident With US Income

A NZ tax resident with US income will generally need to consider that income when preparing their New Zealand tax return because NZ tax residents are generally taxed on worldwide income.

If US tax has already been paid on the same income, a foreign tax credit may be available in New Zealand, subject to the applicable rules and limitations.

A NZ tax resident with US income should also determine whether they have separate US filing obligations. US citizens and US resident aliens are generally subject to US tax on worldwide income even when living outside the United States.

Quick Answer

• NZ tax residents generally report worldwide income.
• US income may need to be included in your NZ tax return.
• US tax already paid does not automatically remove the NZ reporting obligation.
• A foreign tax credit may be available for qualifying foreign tax.
• The NZ–US Double Tax Agreement can affect the final tax treatment.
• US citizens and US tax residents may have additional US filing obligations.

Do NZ Tax Residents Pay Tax on US Income?

Generally, yes.

New Zealand tax residents are generally taxed on their worldwide income. This can include income received from the United States.

Overseas income may need to be reported even when the income is not transferred to New Zealand and even when tax has already been deducted overseas.

For example, a NZ tax resident with US income may receive:

• US salary or wages
• US dividends
• US interest
• US rental income
• US royalties
• US business income
• US investment income
• Certain pension or retirement income

The correct treatment depends on the type of income, your tax residency, where the income arises and any applicable treaty provisions.

What Is the NZ–US Double Tax Agreement?

New Zealand and the United States have a Double Tax Agreement that helps determine how certain cross-border income is treated.

A DTA can potentially:

• Allocate taxing rights between New Zealand and the US
• Reduce certain withholding taxes
• Provide relief from double taxation
• Set rules for specific categories of income
• Address certain dual-residency situations

However, having a DTA does not mean that US income is automatically exempt from New Zealand tax.

For a NZ tax resident with US income, the relevant treaty article and the type of income need to be considered.

For more information, you can review the New Zealand–United States tax treaty information .

What Is a Foreign Tax Credit in New Zealand?

A foreign tax credit is one of the main mechanisms that can help prevent the same income from being taxed twice.

For example, suppose a NZ tax resident with US income receives US investment income and US income tax has been paid or withheld.

If New Zealand also taxes that income, the taxpayer may potentially claim a foreign tax credit for qualifying US tax.

However, the credit is not automatically equal to the amount of US tax withheld.

The applicable credit can be limited by:

1. The tax paid to the other country
2. The New Zealand tax attributable to the same income
3. The amount permitted under the applicable Double Tax Agreement

For more information, see the IRD guidance on foreign tax credits and Double Tax Agreements .

How Does a Foreign Tax Credit Work?

A foreign tax credit is designed to reduce the possibility of the same income being taxed twice.

However, you cannot simply subtract every dollar of US tax from your NZ tax bill without considering the applicable rules.

The calculation can depend on the income type, foreign jurisdiction, tax paid and treaty provisions.

This is why a NZ tax resident with US income should review the foreign tax credit position carefully before filing a return.

Foreign Tax Credit Example

Consider a simplified example.

• US income: NZ$10,000
• US tax paid: NZ$1,500
• NZ tax attributable to that income: NZ$2,000

A foreign tax credit may potentially be available, but the actual credit must be calculated under the relevant New Zealand rules.

The amount of the credit cannot simply be assumed to equal the full amount of US tax paid.

How Do You Report US Income to IRD?

If you receive overseas income while you are a NZ tax resident, you generally need to consider how that income should be reported to Inland Revenue.

IRD requires taxpayers with overseas income to provide the required overseas income information, including through the Overseas Income Summary — IR1261 where applicable.

The information can include:

• Type of overseas income
• Amount of income
• Country or jurisdiction
• Foreign tax credit claimed

Supporting documentation may also be required.

You can review the IRD overseas income reporting guidance for current requirements.

What US Income Does a NZ Tax Resident Need to Consider?

US Employment Income

If you live in New Zealand and work for a US company, do not automatically assume that being paid by a US employer means the income is taxable only in America.

The location where employment services are performed, your tax residence and treaty provisions can all be relevant.

A NZ tax resident with US income should consider both the NZ reporting position and any US obligations before filing.

US Dividends

US dividends are another common source of overseas income for New Zealand residents.

US withholding may apply to dividends paid to nonresident investors, although treaty provisions can affect the applicable rate.

The dividend may also need to be included when preparing your New Zealand tax return.

If you are a NZ tax resident with US income from shares or investment portfolios, keep your dividend statements and evidence of US tax withheld.

US Interest

Interest earned from US bank accounts, investments or other sources can also create reporting obligations.

New Zealand residents generally need to consider overseas interest as part of their worldwide income.

Keeping accurate records of gross interest and tax withheld can make foreign tax credit calculations easier.

US Rental Income

If you own a rental property in the United States, the property may create tax obligations in the US as well as reporting considerations in New Zealand.

The location of the property is particularly relevant when determining the source of rental income.

A NZ tax resident with US income from rental property should keep records of:

• Rental income
• Property expenses
• US tax paid
• Property management costs
• Mortgage interest where relevant
• Exchange-rate calculations

What If US Tax Has Already Been Withheld?

This is one of the most common questions from a NZ tax resident with US income.

US tax withholding does not automatically mean that the income does not need to be reported in New Zealand.

Instead, you generally need to determine:

• What type of income you received
• How much income you received
• How much US tax was withheld
• Whether the US tax qualifies for a NZ foreign tax credit
• Whether the NZ–US DTA affects the result
• How the income should be reported in NZ

IRD guidance confirms that NZ residents need to consider overseas income even where another country has already deducted tax.

What Documents Should You Keep?

Good records are particularly important when dealing with cross-border income.

A NZ tax resident with US income should consider keeping:

• US Form W-2 where applicable
• US Form 1099
• Form 1042-S where applicable
• Brokerage statements
• Dividend statements
• Interest statements
• Rental statements
• US tax payment evidence
• Bank statements
• Exchange-rate records
• NZ tax return information
• Foreign tax credit calculations

IRD advises taxpayers to retain supporting information for overseas income and foreign tax credits.

How Should US Dollars Be Converted to NZ Dollars?

US income needs to be considered in New Zealand dollars when preparing your NZ tax information.

Currency conversion can become important when the amounts are large or when payments are received throughout the year.

Keep a record of:

• US-dollar amount
• Date received
• Exchange rate used
• NZD equivalent
• US tax paid
• NZD equivalent of the foreign tax

For significant amounts, professional advice can help ensure the conversion method is appropriate.

What If You Are a US Citizen Living in New Zealand?

This is a particularly important issue.

Being a NZ tax resident does not necessarily end your US tax obligations if you are a US citizen.

The IRS states that US citizens and resident aliens generally remain subject to US tax on worldwide income while living overseas.

That means someone who is both a NZ tax resident and US citizen may have obligations in both countries.

For example:

• NZ worldwide income reporting
• US federal income tax reporting
• Foreign tax credit considerations
• Potential foreign financial account reporting
• Cross-border treaty considerations

The IRS provides additional information for US citizens and resident aliens living abroad .

What If You Are Not a US Citizen?

If you are a NZ tax resident but not a US citizen or US tax resident, your US obligations depend on the type and source of your US income.

US tax rules distinguish between different types of income and different categories of taxpayers.

For example, US-source investment income may be subject to withholding, while other income may be treated differently depending on the circumstances.

Therefore, a NZ tax resident with US income should not assume that the tax treatment of one US income source applies to every other US income source.

Can You Claim the Same Foreign Tax Credit Twice?

No. You cannot simply claim the same foreign tax multiple times.

Foreign tax credit rules contain specific limitations and calculations.

This can become particularly complicated if you have:

• US dividends
• US interest
• US rental income
• US employment income
• Multiple foreign jurisdictions
• Investment funds
• Business interests
• Trust income

If you have several income sources, professional tax advice can help ensure the foreign tax credit calculation is appropriate.

What About New NZ Tax Residents?

If you’ve recently moved to New Zealand from the United States, your tax position may be different from someone who has been a NZ tax resident for many years.

New or returning NZ tax residents may qualify for a temporary exemption on most types of foreign income for around four years, subject to eligibility and exclusions.

This means residency timing can be extremely important.

If you recently moved from the US to New Zealand, don’t assume that every type of US income is automatically treated in the same way.

You can learn more about NZ tax residency and overseas income through IRD’s guidance for New Zealand tax residents .

7 Common Mistakes NZ Residents Make With US Income

1. Assuming US Tax Means No NZ Tax

US tax paid does not automatically remove your NZ reporting obligations.

2. Leaving the Money in a US Account

A NZ tax resident with US income may still need to report the income even if the money remains in a US bank or investment account.

3. Assuming All US Tax Is Fully Creditable

Foreign tax credits have limitations and eligibility requirements.

4. Ignoring the Income Type

Dividends, interest, employment income and rental income can have different tax treatments.

5. Forgetting US Filing Requirements

US citizens and US tax residents may continue to have US filing obligations while living overseas.

6. Not Keeping Evidence

Without appropriate documentation, proving foreign tax paid can become difficult.

7. Waiting for an IRD Notice

Cross-border tax problems are often easier to address when identified before a filing issue develops.
