      Budget 2027 introduces five targeted enhancements to Ireland’s research and development (R&D) tax credit, alongside changes to the Knowledge Development Box (KDB).

      Together, the measures are intended to improve access to the credit, support collaboration, and provide greater certainty for businesses undertaking R&D in Ireland.


      Key measures

      • Increased limits for outsourced R&D

        The limits applying to payments made by claimant companies in respect of R&D activity outsourced to unconnected third parties and third-level institutions will increase from the greater of 15% of a company’s non-outsourced R&D expenditure or €100,000 to the greater of 20% of non-outsourced R&D expenditure or €200,000.


        This change should provide greater flexibility to access external expertise and encourage collaboration between businesses and third-level institutions. The limits are linked to a claimant company’s ‘in-house’ R&D costs, which reinforces the key policy objective of creating and maintaining highly skilled R&D employment by the claimant company.

      • Higher first-year payment threshold

        The first-year payment threshold will increase from €87,500 to €105,000. Companies with an R&D tax credit claim of €105,000 or less will receive the full benefit of their claim in the first year. Claimants with credits between €105,000 and €210,000 will also benefit by receiving their refunds more quickly than those with larger claims. The measure is designed to improve access to funding, particularly for small and medium-sized enterprises (SMEs).

      • Improved preliminary corporation tax treatment

        Budget 2027 provides for improved recognition of the R&D tax credit when calculating preliminary corporation tax. This is expected to provide a cash flow benefit where a company offsets its R&D tax credit against tax liabilities.

      • New 5% uplift for supporting R&D costs

        A new provision has also been announced which will allow a claimant company to increase its qualifying R&D cost base by 5% of its qualifying R&D wage costs, subject to having incurred a sufficient level of expenditure.


        The measure recognises that R&D-active companies incur additional supporting costs to carry out R&D projects that may not otherwise fall within the definition of qualifying R&D expenditure.


        While this is a positive enhancement, we look forward to further clarification with respect to the requirements for companies to have incurred “a sufficient level of expenditure” and how this will apply.

      • Simplification for regulated clinical trials

        Budget 2027 proposes an amendment in respect of clinical trials. Where a clinical trial is regulated, this may be used by claimant companies to satisfy the science test for R&D tax credit purposes. The proposed amendment is intended to recognise R&D work carried out by Irish companies as part of global trials.


        It should be particularly relevant to the pharmaceutical, biotechnology and medical device sectors, where trials involve rigorous scientific methods, extensive testing, and the resolution of technological uncertainty. The measure is expected to reduce compliance costs, improve certainty and support Ireland’s position as a location for R&D and clinical research.


        This measure will be provided for at Committee Stage of the Finance Bill as technical work on the relevant legislation is ongoing.

      • Knowledge Development Box

        In addition to the R&D tax credit enhancements, Budget 2027 extends Ireland’s Knowledge Development Box (KDB) regime to 1 January 2032.  The KDB regime has had only a limited number of claimants availing themselves of the relief since its introduction in 2016.


        Budget 2027 also introduces a time-limited option for existing claimants to elect out of the KDB regime, subject to certain conditions. This is a welcome announcement and should provide flexibility for companies that have claimed KDB in the past but may not wish to continue submitting claims.


        The evolution of the international tax landscape (e.g. Pillar Two) has meant that companies that may previously have claimed the KDB may no longer receive any benefit from their KDB claims.


      The measures build on the increase in the headline R&D tax credit rate from 30% to 35% in last year’s Budget. Many of the enhancements also reflect proposals in the Department of Finance’s “Research and Development Tax Credit and Innovation Compass”, published in February 2026.

      KPMG insights – our view

      The enhancements announced by Budget 2027 are welcome and represent positive developments for Ireland’s R&D tax credit regime. These enhancements, coupled with the increase in the headline rate to 35% in Budget 2026, maintain Ireland’s R&D tax credit as highly competitive internationally.

      One key area of focus contained within the R&D Compass is dedicated support for innovation, otherwise referred to as an Innovation Tax Credit. The intention is that this would support high-value and strategic innovative projects which may not fall within the R&D tax credit definition.

      Despite the positive announcements in Budget 2027, there was no reference to any innovation support or tax credit.  However, to ensure that Ireland does not fall behind its international peers as an innovation hub and to maintain its competitiveness, we would recommend that options for the implementation of an innovation tax incentive continue to be examined for future Budgets.
