Claiming Research and Development (R&D) tax credits in the UK allows innovative companies to recover a proportion of their R&D costs through tax relief. Whether you’re developing new products, improving existing technologies, or solving complex technical challenges, eligible R&D activities can lead to significant financial benefits.
What is the R&D additional information form?
The Additional Information Form is a mandatory submission to HMRC that supports your company’s claim for Research and Development (R&D) tax relief or R&D Expenditure Credit (RDEC). It applies to all companies making R&D claims for accounting periods starting on or after 1 April 2023. This must be submitted the same day (or before) as your Company Tax Return (CT600) making the claim.
What you need to include
Company Details:
- Unique Taxpayer Reference (UTR)
- Contact details for the company and any agents
For each project, you must describe in detail:
- The field of science or technology involved
- The advance being sought
- The uncertainties faced
- Why those uncertainties could not be easily resolved by a competent professional
- The steps taken to resolve them
- Details of the qualifying expenditure for each project
This form is essential for validating your R&D claim. It helps HMRC assess whether your projects meet the criteria for scientific or technological advancement and ensures transparency in your claim process.
Failure to submit the form correctly and on time will result in your R&D claim being invalid, even if the rest of your tax return is accurate.
