The integration of artificial intelligence (AI) into the preparation of R&D tax credit claims is transforming a traditionally manual and time-intensive process. From automating information gathering to analysing technical narratives, AI has the potential to improve both the efficiency and accuracy of claim preparation.

However, this emerging capability has generated mixed reactions across the industry, and rightly so. The application of AI must be carefully managed, particularly when used in connection with complex tax legislation and eligibility rules.

When guided by experienced tax professionals, AI can be a powerful tool in enhancing the robustness and defensibility of an R&D tax claim. Left unchecked or used without appropriate oversight, however, can expose claimants to avoidable compliance risks.

The Role of AI in R&D Tax Credit Preparation

AI is being used in a variety of ways across the R&D tax credit process. These include:

Automated data extraction from technical documents, meeting transcripts and project notes to reduce administrative burden

Natural  language processing (NLP) to draft or structure responses for the Additional Information Form (AIF), aligning with HMRC’s expectations

Classification algorithms to help identify qualifying R&D activities based on the BEIS and CIRD guidance

Comparative analysis across previous claims or internal case studies to ensure  consistency in reporting

Real-time flagging of common risks or missing information that could trigger HMRC scrutiny

‍

When used correctly, AI enables professionals to devote more time to advising clients and assessing eligibility rather than wrestling with paperwork. It supports better documentation and a faster turnaround.

Enhancing Claims with Expert-Led AI Use

In the hands of a Chartered Tax Adviser, AI can significantly improve the quality and defensibility of an R&D tax credit claim by:

• Ensuring technical language is aligned with legislative definitions
• Cross-referencing terminology with HMRC’s CIRD manual and GfC3 criteria
• Structuring claim narratives to clearly demonstrate the scientific or technological uncertainties, the advance sought and the systematic approach taken which are the core principles of a legitimate R&D claim
• Highlighting gaps or inconsistencies early in the process, giving professionals time to refine the submission before it reaches HMRC
• Streamlining the collation of supporting documentation such as patent filings, grant applications, and engineering reports

‍

With expert oversight, AI does not replace human judgement; it amplifies it.

The Limitations of AI Without Professional Oversight

Despite its many benefits, AI is not without its limitations. It does not possess a deep understanding of R&D legislation or sector-specific eligibility criteria. Misinterpretation or generic responses generated without human review can lead to:

• Overstated claims that do not meet the strict definitions under UK legislation
• Poorly drafted narratives that fail to demonstrate how the project overcame uncertainty
• Submissions that miss critical supporting evidence, increasing the likelihood of an HMRC enquiry or adjustment
• Misinterpretation of commercial innovation as technological advance, leading to non-compliance with BEIS guidelines

‍

Inaccurate or unsubstantiated claims can risk financial penalties and reputational damage with HMRC. AI should not be treated as a substitute for professional expertise, especially in an environment that demands precision.

‍

Conclusion: Experience + Technology = Better Outcomes

AI has a meaningful role to play in the future of R&D tax credit preparation. But its value is best realised when combined with professional experience, technical understanding and ethical judgement. In the hands of trained tax advisers, AI can accelerate workflows, reduce errors and help companies realise the value of their innovation more effectively.

Used responsibly, the combination of human expertise and smart technology can raise the standard of claims across the board.
