What goes into the technical documentation?

by Tom Heslin

The technical documentation in a research and development (R&D) tax credit claim should provide a compelling demonstration of the technological innovation(s) that your company has sought, the challenges you faced, the resources used, and the outcomes achieved. 

There is no standard format for presenting the information in a technical documentation to HMRC. However, it will usually begin with a background of your company to explain the context of your R&D work.

The technical documentation describes how a company’s activities and projects have been assessed to determine if they qualify for the R&D tax credit incentives. There may be commercial aspects of a project which cannot be included; these should be isolated. In this way, the documentation should be able to detail how your associated costs have been treated.

Sample projects in an R&D tax credit technical documentation

You should also include case studies that explain some example projects in detail. These demonstrate to HMRC that the guidelines for R&D are being properly applied and have been understood.

The case studies need sufficient detail for an HMRC inspector to understand how the projects you have undertaken have been assessed, and how they align with the R&D guidelines. As far as possible, you should explain your projects in layman’s terms, but be careful to explain the technological complexities you faced in enough detail to support your claim.

As well as explaining the associated costs and some example projects, your technical documentation might include:

  • Some contextual information about your company;
  • Some details of the key individuals who have worked on your projects; and
  • Some of the technical difficulties you encountered in your projects.
