The UK tax authority, His Majesty’s Revenue and Customs (HMRC) has released a report, which was commissioned to BMG, on regional data on Corporate Tax reliefs on 24 April 2025, detailing research on R&D tax relief for SMEs, the R&D expenditure credit, and the Patent Box

The overarching aim was to understand the regional spread of activities underlying R&D. The core objectives of this research were to:

  • understand the firmographics of businesses claiming these tax reliefs
  • understand where research and product development is taking place and how activity is split across multiple locations
  • understand the level of activity taking place across different regions
  • understand whether the regions where activity is taking place are different from where the claims are being made or the company is registered
  • explore companies’ R&D activities in more detail.

The research consisted of 525 interviews with SME claimants, 201 interviews with RDEC claimants and 89 interviews with Patent Box claimants. The same questionnaire was used for SME and RDEC claimants, a separate questionnaire was developed for Patent Box claimants.
