Tax advisory & planning
in New Zealand.

New Zealand has concluded double taxation agreements with over 40 jurisdictions, including Australia, the United Kingdom, the United States, Japan, China and most major trading partners in Asia and Europe. DTAs take precedence over domestic law where they provide a more favourable outcome for the taxpayer.

For companies with cross-border operations, DTAs primarily affect two areas. First, they determine whether a foreign company’s activities in New Zealand create a taxable permanent establishment. Second, they reduce withholding tax on dividends, interest and royalties below the default domestic NRWT rates of 15%, with the specific reduced rate varying by jurisdiction and payment type.

To access treaty benefits, a company must be tax resident in the relevant treaty partner country and provide evidence of that residency to the New Zealand payer. Where no DTA applies, unilateral foreign tax credits may still be available to reduce double taxation on the same income. For a full overview of how DTAs interact with New Zealand’s corporate tax framework, see our international taxation guide.

New Zealand requires multinational companies to price cross-border related-party transactions on an arm’s length basis under sections GC 6 to GC 14 of the Income Tax Act 2007, aligned with the OECD Transfer Pricing Guidelines. The rules were strengthened by BEPS reforms in 2018, which shifted the burden of proof to taxpayers. Documentation is not filed with tax returns but must be provided to Inland Revenue upon request.

New Zealand recognises the OECD master file and local file framework. Country-by-country reporting applies to New Zealand-headquartered groups with consolidated annual revenue exceeding NZD 1.3 billion. Where transfer pricing documentation is absent or inadequate, Inland Revenue may adjust taxable income and apply shortfall penalties of up to 20% for unacceptable tax positions or 40% for gross carelessness. For a full breakdown of documentation requirements, see our transfer pricing guide.

Non-resident withholding tax (NRWT) applies to interest, dividends and royalties paid from New Zealand to non-residents. Default domestic rates are as follows:

• Dividends: 15%
• Interest: 15%
• Royalties: 15%

Where New Zealand has a double taxation agreement with the recipient’s jurisdiction, reduced rates typically apply. For interest payments, payers may elect to pay the approved issuer levy of 2% as an alternative to NRWT, which can reduce the cost of cross-border borrowing where the lender is unrelated. The payer is responsible for withholding and remitting the correct amount to Inland Revenue.

Foreign companies operating in New Zealand through a fixed place of business create a taxable presence and are subject to New Zealand income tax on profits attributable to that presence at the standard 28% corporate rate. A foreign company may register as an overseas company or incorporate a local subsidiary. A subsidiary incorporated in New Zealand is treated as a New Zealand tax resident and is taxed on worldwide income. A branch is taxed only on New Zealand-sourced income.

Both structures require registration with the Companies Office and Inland Revenue, including obtaining an IRD number. GST registration is required if taxable turnover exceeds NZD 60,000 in any 12-month period. Foreign-owned entities are also subject to thin capitalisation rules, which limit interest deductions on related-party debt and should be assessed as part of the initial structuring decision. For a full overview of the tax considerations involved, see our international taxation guide.

New Zealand operates an imputation system designed to prevent double taxation of company profits. When a New Zealand company pays corporate tax at 28% it can attach imputation credits to dividends distributed to shareholders. Fully imputed dividends paid to non-resident shareholders are exempt from non-resident withholding tax, making them the most tax-efficient method of repatriating profits to an overseas parent.

Where dividends are partially or wholly unimputed, NRWT applies at 15% or at the reduced rate available under an applicable double taxation agreement. Imputation credits cannot be utilised directly by non-resident shareholders but their effect is to eliminate the withholding tax obligation on the New Zealand side when the dividend is fully imputed. Companies must maintain an imputation credit account to track credits available for attachment to distributions. For further detail, see our profit repatriation guide.
