Has HMRC changed its tune on R&D tax relief?

For the past few years, the conversation around Research & Development (R&D) tax relief has been dominated by warnings. HMRC has been increasingly focused on tackling incorrect and fraudulent claims, introducing tighter rules, additional information requirements and more compliance checks. So, when HMRC recently published new guidance on R&D tax relief, something stood out. Is the tide finally turning on attitudes towards R&D?

A different message from HMRC

The new guidance, published in July 2026, starts by reminding businesses that R&D tax relief is a government incentive designed to encourage innovation. It highlights the fact that thousands of SMEs already benefit from R&D relief and explains how it can help businesses reduce the cost of innovation, improve competitiveness and reinvest in their businesses.

That might not sound revolutionary, but it is a noticeable change in emphasis from the compliance-heavy messaging we've become accustomed to.

Could it be that HMRC is becoming more confident that the message now needs to be about encouraging legitimate claims, as well as stopping illegitimate ones?

There is certainly evidence that the R&D claims landscape has changed significantly.

HMRC's own estimates suggest that levels of error and fraud have fallen substantially from the highs seen in previous years. At the same time, the number of claims has also fallen following a series of reforms designed to improve compliance and reduce abuse.

That doesn't mean the problem has disappeared. HMRC continues to investigate claims and recover money where it believes relief has been incorrectly claimed. But the picture today is arguably very different from the one that prompted some of the strongest warnings around R&D claims.

Don't assume R&D is just for scientists

One of the most useful aspects of HMRC's latest guidance is its attempt to explain what R&D actually means for tax purposes. For tax purposes, the focus is on whether a project is seeking an advance in science or technology and involves resolving technological uncertainty.

That could mean developing a new manufacturing process, creating software that solves a technological problem, developing a new product or trying to overcome technical challenges that existing solutions cannot resolve.

In other words, there could be R&D happening in a business without anyone necessarily calling it R&D, but there is an important distinction here.

HMRC's more positive messaging shouldn't be interpreted as the rules becoming easier or HMRC taking a softer approach to compliance. Businesses still need to meet the qualifying criteria and be able to demonstrate why their projects qualify.

A new chapter for R&D relief?

Perhaps the most interesting thing about HMRC's latest guidance isn't what it says about the rules themselves, but what it says about the wider R&D landscape.

After several years of tightening the system and tackling questionable claims, HMRC appears keen to remind businesses that R&D relief is still very much available for genuine innovation.

It may not mean that HMRC has changed its tune completely, but perhaps the message is becoming a little more balanced: bad claims will continue to be challenged, but good claims are still very much encouraged.
