Cross-Border Software Payments

When Does Withholding Tax Apply?

When an NZ business pays an overseas supplier for software, or an NZ developer is paid by an overseas customer, does tax need to be withheld? Generally, the answer turns on whether the payment is a royalty.


Withholding tax is tax that the payer must deduct from a payment and pay to the relevant tax authority on the recipient’s behalf. Cross-border royalty payments generally require the payer to deduct withholding tax, subject to any relief available under a Double Tax Agreement (‘DTA’). For software payments, the key question is therefore whether the payment is a royalty, or something else.


This matters both for New Zealand businesses paying overseas software suppliers and for NZ developers receiving payments from overseas customers or subsidiaries.


A payment described as a “licensing fee” may be a royalty, or it may simply be payment for software access. The answer depends on the rights granted, the contractual arrangements and the tax rules in the countries involved.


Why look at this now?

Inland Revenue has released draft guidance on payments to non-resident software suppliers (PUB00266), with consultation closing on 31 October 2026. It updates guidance dating back to 2003, including new discussion of cloud computing and expanded coverage of distributors and resellers.


The draft considers two withholding regimes: non-resident withholding tax (NRWT) on passive income, including royalties and certain interest, and non-resident contractors’ tax (NRCT) on qualifying contractor payments. This article focuses on royalties and NRWT.


When is a software payment a royalty?

The key distinction is between paying to use software and paying for rights to use its underlying copyright or other intellectual property.


A royalty may arise where the payment is for:

  • Rights under copyright, such as rights to reproduce software for sale or distribution, or to adapt it for commercial purposes;
  • Rights to other intellectual property, such as a patent, trademark, design or secret process;
  • Know-how, meaning confidential technical or programming information supplied for the recipient to apply itself; or
  • Assistance that enables the recipient to use those rights or know-how, where it falls within the relevant royalty definition.


By contrast, purchasing software for ordinary end use, subscribing to standard cloud services or obtaining routine technical support generally does not involve paying a royalty. Calling the arrangement a “licence” does not determine its treatment.


For example, acquiring rights to reproduce a program and sell copies to customers is different from purchasing 50 installations for staff use. Similarly, subscribing to an online scheduling platform is different from acquiring rights to adapt and reproduce its underlying software.


Some agreements contain several elements. Where copyright, intellectual property or know-how rights are supplied alongside services, the payment may need to be apportioned so that withholding tax applies only to the royalty component.


Paying an overseas software supplier

Where a payment is a New Zealand-sourced royalty to a non-resident, the NZ payer generally needs to deduct NRWT. The standard royalty rate is 15% of the gross payment, although an applicable double tax agreement (DTA) may reduce this, commonly to 5% or 10%.


The contract determines who bears the commercial cost. If the supplier must receive its fee without any deduction for withholding tax, the NZ purchaser may need to increase, or “gross up”, the payment.


For example, if the supplier must receive $10,000 after tax and a 10% withholding rate applies, the total cost would be $11,111.11: $10,000 paid to the supplier and $1,111.11 paid to Inland Revenue.


Withholding tax clauses therefore deserve attention before the price is agreed.


Receiving payments from overseas customers or subsidiaries

An NZ software developer also needs to consider withholding tax on payments it receives from overseas.

The treatment depends on the payer’s domestic tax rules and the relevant DTA.


If the payment is a royalty, the overseas customer or subsidiary may need to deduct withholding tax in that overseas jurisdiction before paying the NZ company. Treaty relief may reduce the rate, but the requirements for obtaining that relief must be satisfied.


The role of an overseas subsidiary is particularly important when assessing payments within a software group.


What if the overseas subsidiary is simply a local distributor?

Consider an NZ developer that operates a software platform. Its overseas subsidiary markets subscriptions, contracts with local customers and collects their fees. The subsidiary retains a distribution margin and pays the balance to the NZ company.


Under the approach in Inland Revenue’s draft, a basic reseller simply buying and reselling software access generally does not pay a royalty. Limited rights to use the provider’s name, logos or product names for marketing may be incidental and disregarded when classifying the payment.


If the overseas country applies the same classification, the subsidiary’s payment would generally fall under the business profits article of the DTA rather than the royalties article. Provided the NZ company has no Permanent Establishment (broadly, a taxable presence such as a fixed place of business) in that country, that country generally should not be able to tax those business profits, including through royalty withholding tax (sales tax, VAT/GST etc may still apply).


A different outcome may arise if the subsidiary receives substantive rights to reproduce or adapt the software, or rights to other intellectual property or confidential know-how. Providing local support or implementation services does not, by itself, establish that those rights have been granted.


Earning a margin from software sales does not necessarily mean the subsidiary is paying for rights to use the software’s copyright.


Can the NZ company recover overseas withholding tax?

If an overseas customer or subsidiary deducts withholding tax from a royalty payment to the NZ company, the NZ company may be entitled to a foreign tax credit for overseas withholding tax.  However, the credit is limited to the NZ tax payable on the relevant foreign income.


If the NZ company is in a tax loss position, it cannot use the foreign tax credit. This also applies where losses brought forward eliminate its NZ income tax liability. The unused credit cannot be refunded or carried forward, so the benefit is forfeited. Overseas withholding tax correctly imposed becomes a permanent cost to the business or group.


This can be particularly significant for software developers investing heavily in development. Overseas withholding tax may still be payable even while the NZ company is making losses.


Review the arrangement before payments begin

For businesses buying, integrating or distributing software across borders, the questions to ask are:

  • What does each party actually do, and what rights does it receive?
  • Is the payment for software access, copyright rights, development services or a combination?
  • Which country’s withholding rules apply, and what treaty relief is available?
  • Does the agreement allow tax to be deducted, or must the payer bear it?
  • Can the recipient use any resulting foreign tax credit?


For related companies, the intercompany agreement, actual activities and transfer pricing policy should support a consistent treatment.


These questions are best addressed when the arrangement is established. An invoice labelled “software licensing” is not enough to determine the answer.

Artificial intelligence is now part of a growing number of product-development projects. For New Zealand businesses, this raises a practical tax question: could any of the development expenditure qualify for the Research and Development Tax Incentive (RDTI) or the R&D Tax Loss Credit (RDTLC)? The starting point is to identify the particular development activity, the scientific or technological uncertainty being addressed and the systematic process used to investigate it. Two forms of R&D tax support The RDTI generally provides a 15% tax credit for eligible R&D expenditure. It may assist established businesses undertaking R&D as well as earlier-stage companies, subject to the applicable eligibility, approval, expenditure and filing requirements. The RDTLC is directed at eligible loss-making companies. Broadly, it may allow a company to obtain the cashflow benefit of tax losses attributable to qualifying R&D expenditure rather than carrying all those losses forward. It has its own eligibility rules, calculations and future tax consequences. When might AI development qualify? The strongest starting point may be where a business is developing its own AI technology. This could include experimental work on a new model, algorithm, training method or technical architecture where it is not known at the outset whether the required capability or performance can be achieved. However, potential R&D is not limited to businesses creating the underlying AI model. It may also arise when an existing AI model is integrated into a new product and that integration creates technological problems that cannot readily be resolved using existing knowledge and established techniques. For example, experimental development may be required to determine whether an integrated system can: achieve the required level of accuracy and consistency; identify unreliable or fabricated outputs; validate results against trusted data; meet defined processing-speed, scale, security or privacy requirements; operate reliably when information is incomplete or unusual; or continue to perform when a third-party AI provider changes its model. The potentially eligible R&D is the systematic work undertaken to resolve those technical uncertainties. It is not simply the decision to include AI in a product. Using AI to undertake ordinary development Many businesses now use AI assistants to write code, design workflows, analyse data, prepare content or automate routine tasks. These tools may reduce the time and cost of development, but their use does not make the underlying work R&D. If a business uses an AI coding assistant to build a conventional customer portal, for example, the project does not qualify merely because AI generated some of the code. The development activity must independently satisfy the R&D requirements. This distinction is important when preparing a tax credit claim. The relevant question is not how the development team used AI. It is what scientific or technological uncertainty the team was seeking to resolve. Example: an AI-enabled equipment-monitoring system Consider a business developing a platform that monitors specialist industrial equipment. The system receives data from sensors operating under variable environmental conditions and is intended to identify emerging faults before the equipment fails. The business incorporates a third-party AI model but also develops its own analytical layer to interpret incomplete sensor data, distinguish genuine warning signs from background variation and decide when an alert should be escalated for human review. It is not known whether the AI model and the analytical layer can be combined to achieve the required accuracy without producing an unacceptable number of false alerts. Established methods do not provide the answer, so the development team designs and tests different technical approaches against defined performance measures. That experimental work may qualify as R&D. However, the whole platform would not necessarily qualify. Standard dashboard development, customer account functions, routine reporting, deployment and ongoing monitoring may fall outside the eligible core activity. Review eligibility before claiming the credit AI development can involve genuine R&D, including where a business builds its own technology or undertakes experimental work to integrate an external model into a new product. However, neither the use of AI nor the novelty of the finished product determines tax-credit eligibility. Before including expenditure in an RDTI or RDTLC claim, the business should establish: which activities may satisfy the relevant R&D definition; where those activities begin and end; which expenditure is eligible under the applicable regime; and what approvals, returns and supporting evidence are required.

New Zealand’s foreign investment fund (FIF) rules have long caused problems for migrants holding overseas shares, particularly US citizens and Green Card holders living in New Zealand. The United States generally continues to tax these individuals on their worldwide income even when they are tax resident in New Zealand. At the same time, New Zealand’s FIF rules can impose tax on deemed income that does not match the income or gains recognised in the United States. This mismatch can create cash flow problems and, in some cases, double taxation because the tax paid in one country may not be available as a credit in the other. A new revenue account method (RAM) was introduced to address these concerns. However, the original rules were narrowly targeted. Following lobbying from tax advisers, migrants, investors and others affected by the rules, the Government announced a significant expansion as part of Budget 2026. These changes have already been widely discussed. In this article, we explain what they mean, particularly for US citizens living in New Zealand, and provide an update on where they have reached in the legislative process. Why are the FIF rules difficult? The FIF rules generally apply when a New Zealand tax resident holds shares in a foreign company. The most commonly used calculation method is the fair dividend rate (FDR) method. Broadly, FDR taxes 5% of the opening market value of a foreign share portfolio, together with an adjustment for certain shares bought and sold during the year. This can produce taxable income even where: no shares have been sold; no dividends have been received; the investment has produced no cash; or the investment has ultimately fallen in value or failed. This can be particularly harsh for people holding shares in an overseas private company or start-up. Tax may be payable each year on deemed income, even though the company has not paid a dividend and the shares cannot readily be sold to fund the tax. It is also problematic for US citizens. New Zealand may impose tax each year under FDR, while the United States may not tax the gain until the shares are sold. Because the two countries are taxing different amounts at different times, effective foreign tax credits may not be available. RAM: a “pay when you sell” method The new RAM taxes qualifying foreign shares on a realisation basis. Instead of being taxed each year on deemed income, an eligible taxpayer is generally taxed on: dividends received; and 70% of the gain realised when the shares are sold. A corresponding 70% of a realised loss may be recognised, although the use of RAM losses is restricted. For example, if an eligible taxpayer receives a $1,000 dividend and realises a $100,000 gain, their taxable RAM income would generally be: $1,000 dividend + 70% of the $100,000 gain = $71,000. RAM does not impose tax at a flat rate of 70%. Rather, 70% of the gain is included in the person’s taxable income and taxed at their applicable marginal tax rate. This approach is much closer to the capital gains regimes familiar to migrants from countries such as the US. It also means the taxpayer generally has cash from the sale available to fund the resulting tax. RAM was introduced but the initial rules were narrow The original RAM legislation applies from 1 April 2025. However, it is broadly limited to recent migrants and returning New Zealanders who: became fully subject to New Zealand tax on or after 1 April 2024; and had been non-resident for at least five years before becoming resident. Ordinary RAM generally applies only to qualifying unlisted foreign shares acquired before the person became a New Zealand tax resident. An extended version of RAM can cover listed and unlisted shares held by people who remain liable to tax in another treaty country because of their citizenship or right to live and work there. This is principally aimed at US citizens and Green Card holders. However, under the enacted rules, these individuals must still satisfy the recent-migrant requirements. This excludes US citizens who have already lived in New Zealand for several years, even though they face the same double-tax problem. Budget 2026 proposes a major expansion Following lobbying by the tax industry and people directly affected by the rules, the Government announced a broader RAM regime in Budget 2026. The changes would: allow all New Zealand residents to use RAM for qualifying unlisted foreign shares; allow qualifying US citizens and others subject to citizenship-based taxation to use extended RAM for listed and unlisted foreign shares, regardless of when they migrated to New Zealand; and increase the FIF de minimis threshold from $50,000 to $100,000. The removal of the recent-migrant restriction from extended RAM will be particularly helpful for US citizens and Green Card holders who have lived in New Zealand for many years. Once enacted, these taxpayers should be able to align their New Zealand tax more closely with the time at which the United States recognises the gain. This should reduce cash flow problems and the risk of tax being paid in both countries without an effective foreign tax credit. The expansion of ordinary RAM will also help New Zealand residents holding shares in overseas private companies. Instead of potentially paying tax each year on an investment that produces no cash, tax would generally arise when a dividend is received or the shares are sold. The de minimis threshold is also increasing Individuals generally do not have to apply the FIF rules where the total cost of their relevant foreign investments does not exceed $50,000. The Government proposes increasing this threshold to $100,000 from 1 April 2026. This should remove many smaller investors from the FIF regime, significantly reducing their compliance costs. The Budget changes are not yet law The expanded RAM rules and the $100,000 de minimis threshold were not included in the Budget night legislation and have not yet been enacted. We expect these changes to be included in the 2026–27 Annual Rates Bill later in 2026. If enacted as proposed, they should apply from 1 April 2026. The detailed legislation will be important. In particular, it should confirm the final eligibility requirements and whether the expanded RAM will be available to companies as well as individuals and qualifying trusts. Until then, taxpayers should distinguish between: the original, narrowly targeted RAM rules, which are already law; and the broader Budget 2026 changes, which remain proposals. Is RAM necessarily the best method? RAM will not always produce the lowest amount of New Zealand tax. FDR may be more favourable where an investment increases significantly in value because annual FIF income is generally based on 5% of opening value. Under RAM, 70% of a realised gain becomes taxable when the investment is sold. The method chosen can also have longer-term consequences. It may not be possible to move freely between RAM and the existing FIF methods, and leaving RAM may trigger a deemed disposal. The choice should therefore be made after considering: the nature and expected performance of the investments; whether the shares are listed or unlisted; when they were acquired; the taxpayer’s New Zealand residency history; the taxpayer’s US tax obligations; the availability and timing of foreign tax credits; and the treatment of losses. A welcome and practical change The proposed expansion of RAM is a welcome response to concerns raised by the tax industry and the people directly affected by the FIF rules. It should reduce the risk of taxpayers having to fund tax on income they have not received, provide much-needed relief for long-term US citizens living in New Zealand and make New Zealand a more attractive place for migrants and returning New Zealanders to live and invest. However, the rules are complex, and the choice of method matters. US citizens and other affected investors should review their portfolios before preparing their FY26 tax returns and obtain coordinated New Zealand and overseas tax advice.

How To Prepare For Your Year-End Accounting.

The Government has recently released a proposal that would fundamentally change how shareholder loans are taxed in New Zealand (Officials’ Issues Paper Improving taxation of loans made by companies to shareholders). At its core, the proposal could turn loans from a company to shareholders into a deemed dividend. Broadly, where a company advances funds to a shareholder and that loan is not repaid within a specified period, the outstanding balance would be treated as taxable income to the shareholder, most likely as a deemed dividend. This would apply to new loans made on or after 4 December 2025, with a proposed $50,000 de minimis per company (not per loan). This would mean that, for example, money taken out of a company by shareholders and left in an overdrawn current account could be treated as taxable income for the shareholders. Alongside this, Inland Revenue proposes a separate rule for companies that are removed from the Companies Register. Any shareholder loan still outstanding at the time of removal would be taxed at that point, on the basis that these loans are frequently never repaid and Inland Revenue has no practical way to recover tax once the company no longer exists. The stated problem: large loans that are never repaid Inland Revenue’s explanation for these changes relies on the concern that shareholders are taking funds out of the company, not declaring dividends, and not paying the funds back. The concern is not ordinary short-term lending. It is large shareholder loan balances that: build up over many years, fund private consumption, are never realistically repaid, and are often abandoned when a company is liquidated or removed from the register. From Inland Revenue’s perspective, these arrangements allow shareholders to enjoy company profits without ever paying shareholder-level tax, while IRD has (apparently) no effective recovery mechanism once the company disappears. That concern is understandable. However, the difficulty lies in how far the proposed solution strays from that original framing and the practical reality of how to implement the proposal. The $50,000 de minimis tells a different story Despite repeated references to very large balances and long-term non-repayment, the proposed rules would apply once shareholder loans exceed a $50,000 de minimis. This threshold applies to the company, so it will include all shareholder loans, not on a loan-by-loan basis. That threshold is not particularly high in the context of owner-managed businesses and does little to confine the rules to the behaviour Inland Revenue says it is targeting. In practice, the proposals could capture many ordinary commercial arrangements that bear little resemblance to the “never repaid” loans highlighted in IRD’s communications. New Zealand’s deliberate departure from Australia This tension becomes clearer when compared with Australia. Australia is cited as a model for taxing shareholder loans, but the Australian regime includes a critical safeguard: a commercial loan exemption. Where a shareholder loan is structured and documented on commercial terms, it is not treated as a disguised (or deemed) dividend. Inland Revenue has rejected adopting a similar exemption for New Zealand. The Issues Paper states that a commercial loan carve-out would be too easy to manipulate and would undermine the integrity of the regime. That decision has far-reaching consequences. It means that even a genuinely commercial loan, indistinguishable from third-party debt, remains exposed to the proposed deemed dividend rules purely because the borrower is also a shareholder. When a “loan” is taxed like income but still behaves like a loan Rejecting a commercial loan exemption also creates a series of unresolved technical and practical issues. If a shareholder loan is deemed to be income for tax purposes, but continues to exist legally, several questions follow: What happens to interest? Is this still taxable income for the company? Remember that, for tax purposes, the loan has been repaid via a deemed dividend. How are repayments treated? If the shareholder later repays the principal, should there be a deduction available to the shareholder for that repayment? i.e., to reverse the tax impact of the deemed dividend? What about future dividends? At this stage, the deemed dividend appears to be a tax fiction. The retained earnings remain in the company for accounting purposes. Unless the deemed dividend is matched by a reduction in retained earnings or tracked some other way, the same underlying profits could be distributed again later as an actual dividend — and taxed again in the ordinary way. What this would mean in practice From a practical perspective, the proposals would mean that overdrawn shareholder current accounts could be treated as taxable income for the shareholder, rather than simply being viewed as loans that remain outstanding. Inland Revenue has framed the changes around situations where large shareholder loans are not repaid, and shareholder-level tax is not ultimately collected. The proposed rules would apply more broadly than those scenarios, including to loans that are documented, interest-bearing, and intended to be repaid. As the proposals currently stand, further guidance will be needed on how deemed income amounts interact with ongoing loan balances, interest payments, repayments of principal, and future dividends funded from the same company profits. These interactions will be important in determining the overall tax outcome.
