The R&D Tax Relief Guide for Software Leaders

Don't get caught out by HMRC's changes to Software R&D Tax Credits

In the last couple of years, there have been a number of changes to the R&D tax credit scheme, the most significant of which was a document issued in October 2018 called CIRD81980 - Case Studies demonstrating R&D tax credit claims for software projects. 

The primary goal of the document is to define boundaries, particularly those detailing what qualifies for R&D, and what doesn’t.

HMRC defines R&D as taking place “when a project seeks to achieve an advance in overall knowledge of capability in a field of science or technology.” They later go on to say that this focuses on “projects and activities that help resolve scientific or technological uncertainties.”

The guide defines an R&D project as starting when it begins work to resolve uncertainty, and ends when that uncertainty is either resolved, or found to be unresolvable. It is these boundaries that are often the hardest part of any software claim to explain properly to HMRC in a technical narrative.

The advance needs to be an advance in overall knowledge in software technology, not merely an advance in a company’s own knowledge alone, except only when the details of such advance are not publicly available due to the intellectual property being owned by another company. 

As it stands, it means that credits cannot be applied to routine analysis or work that has commercial considerations. However, many software businesses are finding that the number of challenges issued by HMRC are increasing, making the counselling of external R&D tax credit experts all the more important.    


Some common examples of software projects that might qualify for R&D tax relief include:  

  • Integration of software and hardware platforms.
  • Software that enables new computer hardware.
  • New methods of capturing, utilising or communicating data..
  • Improvements to programming language.
  • Methods that extend the functionality of software or an operating system.
  • Software development tools. 


Many companies have found it difficult to determine when R&D begins and when it finishes. There is also confusion when it comes to differentiating between commercial projects and R&D, and differentiating between which parts of a software project are claimable and which parts are not. 

In order to combat these issues, HMRC published CIRD81980, containing a number of case studies that showed where the boundaries in software claims are, what costs can be claimed and what costs can’t.  

All these influences have led to R&D software claims becoming rather nuanced processes. Here’s an example of what we mean: 

It may be obvious that marketing costs or implementation bug-fixing costs are not claimable, but there is a category of costs called qualified indirect activity that can be included in a claim.

Say you’re building a test harness for a new piece of software algorithm: the algorithm itself may have been an attempt to solve technical uncertainty, but it can’t be tested without the test harness. Hence the harness creation costs will qualify as indirect activity whereas the algorithm qualifies directly, meaning that although they’re both working towards solving technical uncertainty, they satisfy different criteria in different ways.  


It’s clear from the examples contained within CIRD81980 that documenting and qualifying a software claim is by no means a quick and simple process. Getting the maximum amount out of a claim while satisfying all of the required criteria needs experienced and skilled specialists. 

HMRC challenges can be a difficult and lengthy process; introducing a competent professional to carry out the exchange can therefore help to navigate the complexities of making a claim and save a considerable amount of time. 

MSC R&D are fortunate enough to have a low challenge rate with the claims we work on. This is due to the fact that we employ many former HMRC employees and specialists who understand how to properly interact with and satisfy one of the largest financial institutions in the country.
