Research and development – apply for advance assurance – HMRC publish guidance

18 May 2026

HMRC have published the following new guidance on applying for advance assurance when making a claim for research and development tax relief:

  • Apply for targeted advance assurance on up to 2 areas of your Research and Development (R&D) tax relief claim – “Ask HMRC for assurance on particular areas of your Research and Development (R&D) tax relief claim, if you’re a small or medium-sized enterprise (SME).”
  • Apply for full claim advance assurance on your first Research and Development (R&D) tax relief claim – “Ask HMRC for assurance on your first Research and Development (R&D) tax relief claim, if you are a small or medium-sized enterprise.”
