The UAE launched Phase 1 of its Research and Development (R&D) Tax Incentives Programme in March 2026. For businesses operating across multiple jurisdictions, or groups considering where to locate development activity, an important question is how the new regime compares with the UK and Irish schemes that have been established for more than two decades.
The technical principles are familiar. However, there are important differences in how the schemes are structured and administered.
Three schemes, one underlying test
UK R&D incentives have existed since 2000, while Ireland’s R&D corporation tax credit was introduced in 2004. Both have evolved significantly, including the UK’s move to a merged expenditure credit for accounting periods beginning on or after 1 April 2024, and Ireland’s increase in the R&D tax credit rate to 30%, with a further increase to 35% for later periods.
The UAE regime is newer, but its technical principles will be familiar to businesses with UK or Irish experience. Qualifying activity must involve novelty and creativity, address uncertainty, be undertaken systematically and produce results that are transferable or reproducible.
In practice, similar activities can potentially qualify across all three jurisdictions. This could include developing software architecture that existing platforms cannot support, redesigning manufacturing processes to achieve outcomes current methods cannot deliver or testing new materials and engineering solutions where the result could not be known in advance.
The key differences are how this activity is evidenced, approved and valued.
Where the schemes diverge
Value and structure of the benefit
The UK merged scheme provides a 20% above-the-line expenditure credit. After corporation tax, this is worth 15% to 16.2% of qualifying expenditure, with Enhanced R&D Intensive Support providing a more generous route for eligible loss-making SMEs.
Ireland’s R&D tax credit is currently 30% of qualifying expenditure, payable in instalments and is scheduled to increase to 35% for later periods.
The UAE Phase 1 credit is non-refundable and tiered, reaching up to 50% of qualifying R&D expenditure, with qualifying expenditure considered up to AED 5 million per period. The headline UAE rate can therefore appear more generous. However, because the credit is currently non-refundable, its value depends on whether the business has a Corporate Tax liability against which it can be offset.
Approval and timing
The biggest operational difference is when businesses need to engage with the process.
In the UK, a claim notification is required for first-time claimants and for companies that have not claimed in the previous three years. An Additional Information Form must be filed with every claim.
Ireland requires first-time claimants and businesses that have not claimed in the previous three years to submit a pre-filing notification at least 90 days before making a claim.
The UAE goes further. Projects require pre-approval from the Emirates Research and Development Council before they can form part of a claim. This means UAE businesses need to consider their R&D evidence and technical narrative while projects are underway, rather than relying primarily on a retrospective process after year-end.
Small Business Relief
The interaction with other tax reliefs is another important difference.
In the UK and Ireland, claiming R&D incentives does not require a business to give up a separate small-business Corporate Tax relief.
In the UAE, however, a business that elects for Small Business Relief cannot claim the R&D Tax Credit for the same tax period. Small Business Relief is available to companies with revenue of AED 3 million or less and has been extended to periods ending on or before 31 December 2029.
For growing businesses, understanding the potential value of each relief is therefore an important part of tax planning.
What does this mean for the technical file?
Across all three jurisdictions, claim quality starts long before a report is written.
Businesses need to demonstrate the technical uncertainty they faced, the alternatives considered, the challenges encountered and the systematic work undertaken to resolve them.
The evidence can be similar across jurisdictions, including design files, test results, method statements, sprint records, CAD, commissioning data and change logs. The difference is how that evidence is mapped against the requirements of each tax authority.
For UAE projects, the pre-approval requirement makes this particularly important. If a project is expected to form part of an R&D claim, the technical narrative needs to be developed while the relevant uncertainties and activities are still current. It cannot simply be reconstructed at year-end.
What should businesses consider?
For groups with development activity across multiple countries, the comparison is practical. Consider where the R&D is being undertaken, which entity bears the costs, which scheme can recognise the activity and when the relevant processes need to begin.
A UK or Irish claim may follow a more familiar retrospective process, whereas UAE projects require earlier technical engagement.
For businesses operating solely in the UAE, the experience of the UK and Irish schemes also provides a useful indication of what robust R&D evidence looks like: contemporaneous records, a clear account of technical uncertainty and expenditure that can be connected to the work undertaken.
Building these processes into normal project activity from the beginning can help create a stronger foundation for future claims.
Looking ahead
The UAE R&D Tax Incentive is new, but the principles behind identifying and evidencing qualifying R&D are well established.
The key difference is timing. The UAE’s pre-approval requirement means businesses need to engage with their technical evidence earlier, while the interaction with Small Business Relief adds another consideration to tax planning.
As the incentive develops, businesses that establish strong technical records now will be better prepared for future changes to the regime.
For businesses operating across the UAE, UK or Ireland, understanding these differences can help ensure R&D activity is identified, evidenced and considered under the relevant regime from the outset.
