Are you submitting an R&D Tax Relief claim to HMRC?

From 1st August 2023, HMRC are requiring that R&D Tax Relief submissions will need to be accompanied by an ‘additional information form’ containing detailed information about your projects. Don’t worry as we take care of this paperwork for you, but we are anticipating that HMRC will incur significant delays in processing claims, therefore we advise you submit your claim this month to avoid delays to your benefit.

If you’re curious to know what HMRC are expecting to see in the form, you can find out what you need to prepare here.

If you have any questions about these requirements, reach out to a member of our team at rrabess@rck.partners.
