1. What Are Double Tax Agreements (DTAs)?

Double Tax Agreements (DTAs) are treaties between two countries designed to prevent individuals and businesses from being taxed twice on the same income. These agreements allocate taxing rights between the two countries and provide mechanisms to resolve disputes and avoid double taxation.

New Zealand has DTAs with over 40 countries, including major trading partners such as Australia, the United States, the United Kingdom, China, and India. These agreements are particularly important for residents earning income overseas or non-residents earning income in New Zealand.

2. Key Objectives of DTAs

• Avoidance of Double Taxation: Ensures that income is not taxed twice in both countries.
• Tax Certainty: Provides clarity on which country has the right to tax specific types of income.
• Prevention of Tax Evasion: Facilitates the exchange of information between tax authorities to combat tax evasion.
• Encouragement of Cross-Border Trade and Investment: Reduces tax barriers for international business and investment.

3. Relevant National Regulations

New Zealand’s DTAs are governed by the Income Tax Act 2007 and the Tax Administration Act 1994. These laws outline how DTAs are applied and enforced. The Inland Revenue Department (IRD) is the government agency responsible for administering DTAs.

Key provisions include:

• Tax Residency Rules: DTAs often rely on residency status to determine which country has taxing rights.
• Source of Income Rules: Income is taxed based on where it is earned or sourced.
• Relief Mechanisms: DTAs provide methods such as tax credits or exemptions to eliminate double taxation.

4. Types of Income Covered by DTAs

DTAs typically cover the following types of income:

• Employment Income: Wages and salaries.
• Business Profits: Income from business operations.
• Dividends, Interest, and Royalties: Investment income.
• Capital Gains: Gains from the sale of assets (though New Zealand does not have a general capital gains tax).
• Pensions and Annuities: Retirement income.
• Real Property Income: Income from rental properties or real estate.

5. Standard Procedures for Applying a DTA

To benefit from a DTA, individuals and businesses must follow specific procedures:

Step 1: Determine Tax Residency

• Use the IRD’s Tax Residency Tool to determine whether you are a New Zealand tax resident or a non-resident.
• Residency is based on factors such as the number of days spent in New Zealand and whether you have a permanent place of abode in the country.

Step 2: Identify the Relevant DTA

• Check whether New Zealand has a DTA with the other country involved. The full list of DTAs is available on the IRD website.

Step 3: Claim Tax Relief

• If you are eligible for relief under a DTA, you may need to complete specific forms, such as:
  • IR330C: For non-residents claiming reduced withholding tax rates on income like dividends, interest, or royalties.
  • IR292: For non-resident contractors seeking an exemption from withholding tax.
• Submit the completed forms to the IRD or your employer/payer.

Step 4: Provide a Certificate of Tax Residency (if required)

• Some countries require a Certificate of Tax Residency to confirm your tax status in New Zealand. You can request this certificate from the IRD.

Step 5: File Tax Returns

• File tax returns in both countries (if required) and claim any tax credits or exemptions under the DTA.

6. Costs Associated with DTAs

There are generally no direct costs for applying a DTA, but there may be associated expenses, such as:

• Fees for obtaining a Certificate of Tax Residency (if applicable).
• Professional fees for tax advisors or accountants to assist with DTA claims.
• Compliance costs for filing tax returns in multiple jurisdictions.

7. Country-Specific Considerations

Each DTA is unique, and the specific provisions depend on the agreement between New Zealand and the other country. Below are some examples of country-specific considerations:

Australia

• The New Zealand-Australia DTA is one of the most comprehensive agreements, reflecting the close economic relationship between the two countries.
• Special provisions exist for trans-Tasman pensions and superannuation funds.

United States

• The New Zealand-US DTA includes provisions for the Foreign Account Tax Compliance Act (FATCA), requiring financial institutions to report on US citizens’ accounts.
• US citizens living in New Zealand must comply with US tax laws, even if they are New Zealand tax residents.

United Kingdom

• The New Zealand-UK DTA includes specific rules for pensions and annuities, ensuring that retirement income is taxed only in the country of residence.

China

• The New Zealand-China DTA includes reduced withholding tax rates on dividends, interest, and royalties to encourage investment between the two countries.

8. Common Challenges and Tips

• Understanding Residency Rules: Tax residency rules can be complex, especially for individuals who split their time between countries. Seek professional advice if unsure.
• Navigating Dual Tax Obligations: Even with a DTA, you may need to file tax returns in both countries. Ensure you understand your obligations.
• Keeping Documentation: Maintain records of income, tax payments, and correspondence with tax authorities to support your DTA claims.
• Seeking Professional Advice: Consult a tax advisor or accountant with expertise in international tax to ensure compliance and maximize benefits.
