R&D Tax Claim changes coming in on 1st August

Published on 19th July 2023Author: Graeme Blair - Partner

if you've been investing in innovation and are planning on making a claim for R&D tax relief, there are some significant changes coming into effect from 1st August.  Make sure you’re up to speed with the requirements for the new additional information form.

It will:

  • Need to be submitted electronically (where exemptions don’t apply)
  • Need to be signed by a Senior Officer from the claimant company, including the name of the agent who advised on the claim
  • Need to include a breakdown of costs in the claim (this form is to go in, alongside an R&D technical report, which will still be used to showcase the methodologies and cost sampling techniques)
  • If not filed alongside the claim, HMRC will have the power to remove the claim from the Companies tax return
  • This is in addition to notifying HMRC that you plan to make a claim for accounting periods post 1st April 2023 (if you are claiming for the first time or your last claim was 3 years before the last date of the claim notification period).
