Is there a standard format I need to use to provide the information to HMRC?

Your R&D tax credit claim is submitted along with your corporation tax return (CT600) and is required to be submitted digitally.

HMRC does not provide a specific template for the supporting information, but they do specify the type of details they require for an R&D tax credit claim. This includes a breakdown of the qualifying expenditure and a description of your R&D activities.

After determining the benefit using an R&D tax credit calculator, you must enter this information in your company tax return (CT600). This includes the enhanced qualifying R&D expenditure, and if applicable, the payable tax credit amount.
