HMRC are not able to approve or endorse applications such as RDECX. The index has been discussed in detail with HMRC R&D specialists however, at launch, there will be a significant proportion of the HMRC R&D team who will not be familiar with the index. However, even with use of the index, projects should still be evaluated in line with ongoing HMRC requirements. HMRC will be provided with a universal log in to RDECX and so our expectation is that familiarity with the index will increase over time.
