Australia to NZ Tax: What Australians Need to Know About New Zealand Tax

Quick Answer: What Should Australians Know About NZ Tax?

If you live in Australia and are moving to New Zealand, working in New Zealand, owning NZ property, investing in New Zealand or earning income across both countries, your tax obligations can depend on your New Zealand tax residency, the source and type of income and the Australia-New Zealand tax treaty.

New Zealand tax residency is different from immigration or citizenship status. Under New Zealand’s domestic rules, you can become a NZ tax resident if you have been in New Zealand for more than 183 days in any 12-month period, or if you establish a permanent place of abode in New Zealand. The 183-day test is backdated to the first of those days.

New Zealand tax residents generally pay tax on worldwide income, while non-resident taxpayers generally pay New Zealand tax on income from New Zealand sources.

This means an Australian living in Sydney who owns an Auckland investment property may have NZ tax obligations even while remaining Australian-based.

What Is Australia to NZ Tax?

Australia to NZ tax refers to the New Zealand tax considerations that can arise when an Australian resident moves to New Zealand, works in New Zealand, earns NZ income, owns New Zealand property or has financial interests across both countries.

There is no single tax rule that applies to every Australian moving to or investing in New Zealand.

Your tax position can depend on factors such as:

• Where you are tax resident
• How long you spend in New Zealand
• Whether you have a permanent place of abode in New Zealand
• Where your income is earned
• Whether you own NZ property
• Whether you operate a business
• Your Australian investments
• Your New Zealand investments
• Your employment arrangements
• The Australia-New Zealand Double Tax Agreement

7 Essential Australia to NZ Tax Rules Australians Need to Know

1. NZ tax residency is different from immigration status

One of the first things Australians moving to New Zealand should understand is that immigration status and tax residency are separate concepts.

Being an Australian citizen or holding a particular New Zealand visa does not, by itself, determine your New Zealand tax residency.

New Zealand uses specific tax residency rules to determine whether an individual is a NZ tax resident or non-resident taxpayer.

2. The 183-day rule can make you a NZ tax resident

Under New Zealand’s domestic tax rules, you generally become a NZ tax resident if you are in New Zealand for more than 183 days in any 12-month period, unless a specific exception applies.

The days do not have to be consecutive. Parts of days can also count as whole days. If you become resident under this test, your residency is generally backdated to the first of the 183 days.

3. A permanent place of abode can also matter

The 183-day test is not the only consideration.

You can also become a New Zealand tax resident if you have a permanent place of abode in New Zealand.

When considering whether you have a permanent place of abode, factors can include your connections with New Zealand, how often you return, your family and social connections, economic interests, employment or business connections and whether you intend to return to live in New Zealand.

This means an Australian should not assume that spending fewer than 183 days in New Zealand automatically means they are a NZ non-resident.

4. NZ tax residents generally need to consider worldwide income

Once you become a New Zealand tax resident, your NZ tax position can extend beyond income earned inside New Zealand.

New Zealand tax residents generally need to consider worldwide income, including certain income earned from overseas investments, employment, businesses, pensions and property.

This can be particularly important for Australians who move to New Zealand while retaining:

• Australian bank accounts
• Australian shares and investments
• Australian rental property
• Australian business interests
• Australian employment or consulting income
• Superannuation or other overseas financial interests

The applicable treatment can depend on the type of income and the relevant NZ tax rules.

5. Non-residents can still have NZ tax obligations

Remaining an Australian tax resident does not automatically mean you have no New Zealand tax obligations.

Non-resident taxpayers generally pay New Zealand tax on income from New Zealand sources.

For example, an Australian resident who owns an Auckland rental property may need to consider New Zealand tax on rental income from that property.

Similarly, someone working in New Zealand or operating activities that create NZ-source income may have New Zealand tax obligations even if they live in Australia.

6. The Australia-New Zealand tax treaty can affect cross-border income

Australia and New Zealand have a Double Tax Agreement that is currently in force. The agreement contains rules dealing with different categories of cross-border income and can help address situations where income could otherwise be taxed by both countries.

A Double Tax Agreement does not mean that you automatically pay tax in only one country. The relevant treaty provisions depend on the type of income and the individual’s residency circumstances.

Where both countries can tax particular income, domestic foreign-tax-credit rules and the applicable treaty provisions may be relevant.

7. New residents may qualify for a temporary exemption on some overseas income

Some people who become New Zealand tax residents for the first time, or return to New Zealand after a qualifying period overseas, may be eligible for a temporary exemption from NZ income tax on most types of foreign income for around four years.

The exemption has eligibility requirements and does not cover every type of overseas income. The start and end dates also need to be determined correctly.

Australians moving to New Zealand should therefore check whether they qualify before assuming that all Australian income will immediately be taxed in New Zealand.

Do Australians Pay Tax in New Zealand?

Australians may have New Zealand tax obligations depending on their tax residency and the type and source of their income.

For example:

• An Australian moving permanently to Auckland may become a NZ tax resident.
• An Australian living in Sydney may have NZ tax obligations on rental income from an Auckland property.
• An Australian working in New Zealand may have NZ employment income and PAYE obligations.
• An Australian operating a business in New Zealand may need to consider NZ business and tax obligations.
• An Australian investor may need to consider NZ tax rules for New Zealand investments.

The key question is therefore not simply whether you are Australian. It is how the New Zealand tax rules apply to your particular circumstances.

What Happens to Australian Income If You Move to NZ?

Moving from Australia to New Zealand can change how your overseas income needs to be considered for tax purposes.

Once you become a New Zealand tax resident, you will generally need to consider worldwide income for NZ tax purposes.

This can include income from Australian:

• Rental properties
• Shares
• Managed funds
• Bank accounts
• Businesses
• Employment
• Pensions and other income sources

The specific tax treatment depends on the nature of the income, your residency status, any applicable exemptions and the relevant Australia-New Zealand treaty provisions.

What If I Live in Sydney but Own Property in Auckland?

This is a common cross-border tax situation.

If you live in Sydney and own an investment property in Auckland, you may have New Zealand tax obligations on the rental income from the property even though you live in Australia.

Your NZ property tax review may include:

• NZ rental income
• Deductible property expenses
• Mortgage interest
• Property management costs
• NZ income tax filing requirements
• Property ownership structure
• Tax treatment when the property is sold
• Potential Australian reporting requirements
• Application of the Australia-New Zealand tax treaty

You can read more about the NZ rules in our guide to investment property tax .

Do Australians Need to Pay NZ Tax on Rental Income?

An Australian resident who owns rental property in New Zealand may have New Zealand tax obligations on the rental income.

New Zealand’s rules for non-resident taxpayers specifically address rental properties located in New Zealand.

Property owners should keep detailed records of:

• Rental income
• Property management fees
• Rates
• Insurance
• Repairs and maintenance
• Qualifying interest
• Legal and accounting costs
• Property purchase and sale records

The tax treatment of individual expenses depends on the applicable NZ rules.

What If You Work in New Zealand but Live in Australia?

If you work in New Zealand while maintaining connections with Australia, your tax position may involve both countries.

The treatment can depend on factors including:

• Where you physically perform the work
• Your tax residency
• Your employer
• Where the employer is based
• The duration of your work in New Zealand
• The applicable Australia-New Zealand tax treaty provisions

Employees working in New Zealand may also need an NZ IRD number and the appropriate tax code for PAYE purposes.

What About Australian Shares and Investments After Moving to NZ?

Australian investments can require additional review when an Australian moves to New Zealand and becomes a NZ tax resident.

New Zealand tax residents generally need to consider overseas investment income for NZ tax purposes.

Depending on the investment, New Zealand rules for foreign investments may also become relevant. This can include the Foreign Investment Fund regime for certain overseas interests.

If you already have a substantial Australian investment portfolio before moving to New Zealand, it is worth reviewing the NZ tax treatment before your residency position changes.

For more information, see our guide: FIF Changes NZ .

What Happens to an Australian Business When You Move to NZ?

Moving to New Zealand while continuing to operate an Australian business can create cross-border tax and business considerations.

The review may include:

• Where the business is managed
• Where services are performed
• Where customers are located
• Where contracts are entered into
• Whether the business has activities or a taxable presence in New Zealand
• Company and shareholder residency
• GST obligations
• Employment and payroll obligations
• Australia-New Zealand treaty provisions

Business owners should review their structure before relocating rather than assuming that their existing Australian arrangements can simply continue unchanged.

Australia to NZ Tax: Do You Pay Tax Twice?

Cross-border income can potentially be subject to tax in both Australia and New Zealand. However, the Australia-New Zealand Double Tax Agreement and domestic foreign-tax-credit rules can provide mechanisms to relieve or reduce double taxation where the relevant requirements are satisfied.

The result depends on the type of income, your residency status and the applicable treaty provisions.

A Double Tax Agreement does not necessarily mean that the income is exempt from tax in one country. Instead, treaty rules can allocate taxing rights or provide mechanisms for relieving double taxation.

Australia to NZ Tax Example

Consider an Australian resident living in Sydney who owns a rental property in Auckland.

The owner receives rental income from the Auckland property but continues to live and work in Australia.

The owner may need to consider:

1. Whether the Auckland rental income is taxable in New Zealand.
2. Whether a New Zealand tax return is required.
3. Which property expenses can be claimed under NZ rules.
4. How the income needs to be reported in Australia.
5. Whether foreign tax credits or treaty provisions are relevant.
6. What happens if the Auckland property is eventually sold.

This example illustrates why Australia to NZ tax matters can require a review of both countries’ rules rather than relying on a single-country tax calculation.

What Should Australians Do Before Moving to NZ?

If you’re planning to move from Australia to New Zealand, reviewing your tax position before the move can help you identify potential issues early.

Before moving

• Review your Australian and NZ tax residency position.
• List your Australian income sources.
• List your Australian investments.
• Review any Australian rental properties.
• Review your business interests.
• Check whether you may qualify for the temporary foreign-income exemption.
• Understand how your investments may be treated under NZ tax rules.

After moving

• Determine your NZ tax residency date.
• Apply for an IRD number if required.
• Keep records of overseas income.
• Review foreign tax paid.
• Check whether a NZ tax return is required.
• Consider the Australia-New Zealand tax treaty where relevant.

Common Australia to NZ Tax Mistakes

1. Assuming Australian tax residency means no NZ tax

Australian residency does not automatically eliminate New Zealand tax obligations. NZ-source income can still be taxable in New Zealand.

2. Assuming 183 days is the only residency test

A permanent place of abode in New Zealand can also be relevant to NZ tax residency.

3. Assuming citizenship determines tax residency

Tax residency is determined under tax rules and is separate from immigration or citizenship.

4. Forgetting about Australian investments

Becoming a NZ tax resident can mean that overseas income and investments need to be considered under New Zealand tax rules.

5. Assuming the tax treaty means no tax is payable

The Australia-New Zealand Double Tax Agreement does not automatically make cross-border income tax-free. Its provisions depend on the type of income and residency circumstances.

6. Waiting until after the move to review your tax position

Some tax issues are easier to identify and plan for before residency or ownership circumstances change.
