Budget 2026: What the R&D Tax Incentive Changes Mean for Businesses
The Government's Budget 2026 includes a number of changes to the Research and Development Tax Incentive (RDTI).
The changes are generally positive. For businesses claiming the RDTI, the key changes are the proposed introduction of in-year payments, greater administrative flexibility for Inland Revenue and a significant reduction in the cap applying to internal software development expenditure.
Unfortunately, the changes stop well short of a significant expansion of New Zealand's innovation policy settings.
In-Year Payments Could Be the Most Significant Change
The headline change is the proposal to introduce in-year payments of RDTI credits.
Under the current regime, businesses incur R&D expenditure during the year and generally do not receive the benefit of the tax credit until well after balance date. In practice, there can be a delay of 12 to 18 months between expenditure being incurred and the credit being received.
The Government has announced that a new mechanism will be developed to allow businesses to access the benefit of the credit during the year.
While there is little detail available at this stage, the proposal has the potential to materially improve the effectiveness of the regime. However, the benefit of the proposal will depend heavily on the detail.
This is not the first time New Zealand has attempted to provide businesses with early access to the RDTI payouts. The previous regime allowed taxpayers to access in-year RDTI payments; however, it struggled with uptake because the compliance costs associated with obtaining the funding were often too high. Once accountant fees, administration costs and management time were taken into account, the effective cost of accessing the funding outweighed alternative funding sources.
Ultimately, businesses will assess the proposal based on the net benefit received rather than simply the timing of the payment. If accessing an in-year payment requires extensive reporting, frequent Inland Revenue reviews or significant professional costs, the benefit may be largely eroded. Conversely, if the Government can leverage existing General Approval processes and keep compliance requirements relatively light, the proposal could significantly improve the attractiveness of the regime.
The concept is promising, but the practical detail will determine whether this is genuinely helpful.
Inland Revenue Given More Flexibility
A welcome change is the proposal to provide Inland Revenue with greater discretion to deal with administrative defects and late filings.
The current RDTI regime contains strict filing requirements. Missing a deadline means a complete loss of entitlement, even where the underlying R&D activity would otherwise qualify.
This has been a source of frustration for taxpayers and advisors since the regime was introduced.
The proposed changes should allow Inland Revenue greater flexibility to accept late filings and remedy certain procedural issues.
From our perspective, this may prove to be one of the most valuable changes in the package.
Internal Software Cap Reduced
The principal tightening measure announced in Budget 2026 is a significant reduction in the cap applying to internal software development expenditure.
Under the current rules, up to $25 million of eligible internal software expenditure can qualify for the RDTI each year. This cap will be reduced to $3 million.
The change appears to reflect concerns that the regime may have been providing substantial support for large internal software projects that primarily benefit the business undertaking the development rather than generating wider spillover benefits for the New Zealand economy.
For many claimants, this change will have little impact.
What Hasn't Changed?
The core framework of the RDTI remains unchanged. The following key features continue to apply:
- A 15% tax credit;
- A minimum expenditure threshold of $50,000 (subject to approved research provider rules);
- The General Approval process;
- Annual supplementary return requirements; and
- The existing definitions of eligible and ineligible R&D activities.
Businesses will still need to demonstrate that they are attempting to resolve scientific or technological uncertainty through a systematic approach.
Good documentation remains critical.
Positive Signals, but Not a Major Shift
The Budget sends a positive signal that science, innovation and technology continue to be viewed as important drivers of New Zealand's future.
The policy direction appears increasingly focused on ensuring publicly funded research generates tangible economic and commercial outcomes.
However, it is difficult to view the Budget as a major expansion of New Zealand's support for innovation. Most of the announced changes are refinements to the existing framework rather than substantial new investment.
That is somewhat disappointing given New Zealand's long-standing productivity challenges.
For now, Budget 2026 appears to be less about reimagining the RDTI and more about fine-tuning the existing regime. For most claimants, that is still a step in the right direction.
