Competent professional in R&D tax relief: everything you need to know

A ‘competent professional’ in R&D tax relief is a term used by HMRC to determine if the work your business undertakes qualifies for R&D tax credits. When assessing if your claim is eligible, HMRC consults the opinion of this knowledgeable professional in your field to judge if you’re making a legitimate advance in the industry.

What is a competent professional in R&D according to HMRC?

A competent professional (CP) according to HMRC and the department for Science, Innovation and Technology (DSIT) is someone who has the qualifications, experience or authority in your industry to determine if a scientific or technical advancement is necessary to solve a problem in the field.

Your CP should be able to determine which activities seek this advance, and where the R&D activity starts and ends.

Who can be listed as a competent professional?

A competent professional in an R&D claim can be anyone with a high level of expertise, qualifications or experience in your field. This could be your most senior representative, but it doesn’t have to be. For life sciences, this may be a biomedical scientist. In construction, the CP could be an engineer.

Ask yourself:

• Is there only one person working on your R&D project? – If so, this will likely be your CP
• Does one person mainly make decisions about this work? – If so, this is a good candidate for a CP
• Does one person working on your project have more experience, qualifications or authority? – This is a good CP

How do you show evidence of competency for your CP?

Competency is shown through qualifications, track record, and documented judgements on uncertainty and feasibility. HMRC will want to see a named competent professional listed on your R&D tax relief claim, and details of the time they spent on the task, plus evidence of how risks were assessed.

A competent professional in an R&D claim must have:

1. Knowledge – they must understand the scientific and technological aspects you’re working with
2. Awareness – they must have a good grasp of the knowledge in your field
3. Experience – they must have a decent amount of experience and a positive track record in your industry

What is the most important role of competent professionals in R&D claims?

The role of the CP includes span scoping, documenting uncertainty, selecting evidence, and sign-off, streamlining effort and reducing rework across R&D Tax Credits.

How does a CP identify scientific or technological uncertainty?

Only a competent professional can state that an outcome was not readily deducible in the field, applying DSIT’s definition of scientific and technological uncertainty to show why public knowledge could not resolve the problem.

In practice, competent professionals in R&D map the baseline, evidence gaps with recorded trials, and underpin eligibility for R&D tax credits.

How do I distinguish R&D from routine activities?

Competent professionals in R&D tax credits separate routine engineering, debugging, and configuration from qualifying R&D by evidencing work that moved beyond known solutions into experimental development.

They show success was not assured at the outset, consistent with DSIT (Department for Science, Innovation and Technology) and HMRC (His Majesty’s Revenue and Customs) tax credits guidance.

• Qualifying R&D: novel algorithms or processes, prototyping new materials, testing unproven designs
• Non-qualifying routine activities: bug fixing, parameter tuning, standard commissioning

How do I put together a strong technical narrative for HMRC?

Why is a competent professional so important for an R&D claim?

Without a named competent professional for R&D, HMRC may question eligibility and reject your claim. Risk therefore increases for HMRC enquiries, delays, and potential penalties.

How does an HMRC enquiry challenge competency?

During an HMRC enquiry, officers examine who made technical judgements and whether they were suitably qualified. They cross-check titles against responsibilities and ask for relevant evidence.

Your competent professional in R&D tax relief may be questioned – HMRC may ask who identified the uncertainty, what prior research was reviewed, which tests failed and why, and who approved your method changes.

What are the real-world consequences of CPs in tribunal rulings and case studies?

The absence of competent professionals in R&D claims have been denied in the past, even at tribunal. In one case, the tribunal state that to build a strong case for R&D, it’s advantageous to have evidence from competent professional who can testify that the advance you’re seeking is different from what is already available.

How do I document my competent professional?

When you submit your R&D claim, you’ll need to document information about your competent professional, their education, experience and reputation. Competent professionals claiming R&D tax relief should lead the narrative, but other workers can contribute.

Maintain versioned documentation aligned to your cost schedules and narrative to support competent professional R&D tax credits.

What are internal vs external professionals?

Your competent professional in R&D tax credits can be internal or external where appropriate, provided they possess the right authority and knowledge. External specialists may support smaller firms or niche fields.

Internal CPs will be easier to access and give your claim continuity. However, they may have limited capacity. External CPs may offer more thorough expertise. 

If you choose EPW or subcontractors, ensure contracts and records show who made technical decisions, and how they worked on the project.

What are practical steps for documentation and reporting?

Keep a short, living dossier for each project with the competent professional’s credentials, judgements, and evidence. Align it with your technical narrative and cost schedules to boost the evidence of your competent professional’s authority in your R&D claim.

Use a simple template that contains their:

• Name
• Credentials
• Role
• Key judgements
• Artefacts
• Timestamps
• Sign-offs

Support this with meeting summaries, test logs, and an indexed evidence folder. This saves drafting time and speeds up HMRC reviews.

How do I ensure governance and sign-off workflow?

Implement a simple governance path where the competent professional validates scope, reviews evidence, and signs the final claim. This reduces rework and strengthens audit defence against HMRC enquiries.
