Does your work qualify as R&D? The Revenue science and technology test
The R&D tax credit is one of the most valuable supports available to Irish companies, and one of the most misunderstood. Many businesses that genuinely qualify never claim, assuming R&D means laboratories and people in white coats, while others assume any product development counts and claim on work that would not survive scrutiny. Both mistakes come from not understanding the actual test Revenue applies. It is not about your industry; it is about whether your work meets a specific science and technology standard.
This guide explains that test in plain terms: what Revenue means by a scientific or technological advance and uncertainty, the kinds of work that can qualify, and how to tell whether your project is likely to meet the standard before you invest in a claim.
To qualify for the R&D tax credit in Ireland, work must be systematic activity in a field of science or technology that seeks to achieve a scientific or technological advance and involves the resolution of scientific or technological uncertainty. It is the advance and the uncertainty that matter, not the industry: the question is whether you were trying to do something that a competent professional in the field could not readily deduce, and whether you faced genuine technical uncertainty in doing it. Routine work, or applying existing knowledge in a known way, does not qualify, even if it is difficult or commercially valuable.
It is a test of the work, not the sector
This article is general information, not tax advice. Ireland’s R&D tax credit and grant rules are detailed and set by Revenue and the funding bodies, and they change, so confirm the current position with Revenue and take professional advice before you act. McManus McCabe are chartered accountants and can advise on your specific circumstances.
The first thing to understand is that the R&D tax credit is defined by the nature of the activity, not the type of business. Software firms, manufacturers, food producers, engineering companies and many others all claim successfully, because what Revenue examines is whether the specific work meets the science and technology test. Equally, a high-tech company doing only routine work will not qualify. Drop the assumption that R&D belongs to certain industries and focus on whether the work itself meets the standard.
The two things Revenue looks for
A scientific or technological advance
The work must seek to achieve an advance in the overall knowledge or capability in a field of science or technology, not merely an advance for your own company. The question is whether you were trying to create or improve something in a way that was not already readily available or deducible to a competent professional in that field. Making your business better is not enough on its own; the work must push at what is technically known or possible.
The resolution of scientific or technological uncertainty
There must be genuine technological uncertainty: a point where a competent professional could not simply know in advance whether something was achievable, or how to achieve it, and had to resolve that through systematic investigation. If the outcome was reasonably certain and only required applying existing techniques, there is no qualifying uncertainty, however much effort it took. The uncertainty is the heart of the test.
What can qualify, and what usually does not
Work that often qualifies includes developing new or improved products, processes, materials or software where the technical route was not obvious and had to be worked out, integrating technologies in ways that raised real technical problems, and experimental development to overcome technical barriers. Work that usually does not qualify includes:
- 1Routine development using established methods with a predictable outcome.
- 2Cosmetic or aesthetic changes with no technological advance.
- 3Simply adopting or configuring existing off-the-shelf technology in the intended way.
- 4Market research, commercial or financial planning, and routine software configuration.
- 5Work where the only uncertainty was commercial, not scientific or technological.
The difficulty of the work is not the deciding factor. A hard commercial problem solved with known techniques does not qualify, while a smaller project that resolved a real technical unknown might.
How to judge your own project
Before committing to a claim, ask a few honest questions about each project:
- 1Were we trying to achieve an advance in science or technology, beyond what is already available in the field?
- 2Did we face a technological uncertainty that a competent professional could not readily resolve?
- 3Did we investigate it systematically, testing and iterating rather than applying a known solution?
- 4Can we identify the specific technical problem, what was uncertain, and how we sought to resolve it?
If you can answer yes and describe the advance and the uncertainty concretely, the project is worth assessing properly for a claim. If the honest answer is that the work was valuable but technically routine, it is better to know that now than to make a claim that will not stand up.
Getting the assessment right
Whether a project meets the science and technology test is a judgement that rewards experience, because the line between qualifying and non-qualifying work is where claims succeed or fail. As chartered accountants, McManus McCabe can help you assess your projects against the test, identify what genuinely qualifies, and avoid both missing a valid claim and overreaching on one that will not hold.

Frequently asked questions
-
What work qualifies for the R&D tax credit in Ireland?
Work qualifies if it is systematic activity in a field of science or technology that seeks a scientific or technological advance and resolves scientific or technological uncertainty. It is the advance and the uncertainty that matter, not the industry. Routine work using known methods with a predictable outcome does not qualify, even if it is difficult or valuable. -
Does my industry decide whether I can claim R&D?
No. The credit is defined by the nature of the work, not the sector. Software, manufacturing, food, engineering and many other businesses claim successfully, while a high-tech company doing only routine work would not. The test is whether the specific activity meets the science and technology standard. -
What is technological uncertainty?
It is a point where a competent professional in the field could not simply know in advance whether something was achievable, or how, and had to resolve it through systematic investigation. If the outcome was reasonably certain and only required applying existing techniques, there is no qualifying uncertainty, however much effort was involved. -
Does difficult or expensive work automatically qualify?
No. Difficulty and cost are not the test. A hard commercial problem solved with known techniques does not qualify, while a smaller project that resolved a genuine technical unknown might. The deciding factors are the scientific or technological advance sought and the uncertainty resolved.
