You will need to describe the type of R&D your company is doing. 

You will need to complete three sections: 

  1. Key details
  2. Provide the project name, contact details and confirm the tax year the R&D claim is for.

  3. R&D activity
  4. Provide information about the R&D activity you're doing and if it's eligible for the purposes of the tax loss credit.

  5. R&D expenditure
  6. You must spend 20% or more of your total labour expenditure on R&D.

    You will need to provide a breakdown of the total labour expenditure and R&D labour expenditure.

    R&D expenditure is incurred on R&D related goods and services. Certain expenditure is excluded.
