R&D Tax Relief Reform

Lifecycle: Response Published HM Revenue & Customs · HM Treasury Last regenerated 4 days, 2 hours ago

Summary

What this is

HM Treasury and HMRC are reforming the UK's R&D Tax Relief system, merging the existing RDEC and SME schemes into a single merged scheme, introducing enhanced support for R&D-intensive SMEs, and consulting on advance clearances to reduce fraud and error.

Why it matters

R&D tax reliefs cost the Exchequer several billion pounds annually and are a primary lever for stimulating business investment in innovation; reform aims to improve value for money, reduce abuse, and widen eligibility including to arts, humanities and social sciences research.

Current status

The merged RDEC scheme is now in force following the November 2023 legislation; the advance clearances consultation closed in May 2025 and its outcome was published in November 2025, alongside administrative changes to R&D and creative industries reliefs.

Open questions & gaps

Known gaps in the evidence base and what's still pending.

Pending in the lifecycle

  • Government response to the advance clearances consultation has been published but no draft legislation or statutory instrument implementing the expanded clearance regime has yet appeared on this thread.
  • The administrative changes note (pk=31601) references three changes to R&D and creative industries reliefs but no accompanying draft SI or Finance Bill clause has been published on this thread.

Beyond the corpus

  • MISSING Draft statutory instrument or Finance Bill provisions implementing the advance clearances regime — Following a consultation outcome, we would normally expect a draft SI or Finance Bill clause to be published for technical scrutiny before enactment.
  • MISSING Full Equality Impact Assessment (not just screening) for the merged scheme — The screening EIAs (pk=35338, pk=35455) indicate a full assessment may be warranted; no full EIA has appeared on this thread.
  • MISSING HMRC compliance/evaluation data on error and fraud rates under the merged scheme — One stated objective of the reform is to reduce error and fraud; an evaluation or compliance report would be expected within 1-2 years of the merged scheme going live.

Confidence gaps

  • The exact legislative vehicle (Finance Bill clause number or SI reference) for the November 2025 administrative changes (pk=31601) is not identifiable from the events list alone.
  • No sponsoring minister names are grounded in the events list; ministerial responsibility may have shifted across the Conservative-to-Labour transition in 2024 and cannot be confirmed without additional evidence.
  • The scope of the three administrative changes in pk=31601 is described only at a high level; the precise policy content cannot be fully characterised without reading the underlying document.
