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Inland Revenue has released draft guidance on payments to non-resident software suppliers (PUB00266), with consultation closing on 31 October 2026.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.
