HM Revenue & Customs: Enquiry Support Service for R&D Tax Claims
Typical Enquiry Process
Enquiries start with a compliance check letter giving you 30 days to respond. You may receive follow-up requests, calls, or interviews with HMRC’s technical and financial teams. HMRC will then make a decision which you can accept or appeal.
You might get a ‘nudge letter’ asking if your company’s tax affairs are up to date—this often precedes an enquiry. If your R&D tax claim is delayed beyond three to six months without updates, a compliance check is likely underway.
Outcomes of HMRC enquiries can include delayed payments, claim reductions, reputational impact, and fines. To reduce the risk of enquiries, submit robust, accurate R&D tax claims.
