What Is the R&D Tax Claims Notification Form?
The R&D tax claims notification form is a document submitted to tax authorities to declare your company’s R&D activities and expenses. It provides detailed information about the projects you consider eligible for R&D tax relief. The form acts as a formal notification that your business is claiming relief and helps tax officials assess the validity of your claim.
Completing this form correctly is crucial because it:
Demonstrates compliance with tax rules
Provides evidence of your R&D activities
Helps avoid delays in processing your claim
Reduces the risk of audits or penalties
Key Sections of the Notification Form
The form typically includes several sections that require specific information. Understanding what each section asks for will help you prepare accurate and thorough responses.
1. Company Information
This section collects basic details about your business, such as:
Company name and registration number
Contact details
Accounting period relevant to the claim
Make sure this information matches your official company records to avoid confusion.
2. Description of R&D Projects
Here, you must describe the projects you believe qualify as R&D. This description should:
Explain the scientific or technological uncertainties your project aimed to resolve

For example, if your company developed a new software algorithm to improve data processing speed, describe the technical challenges and how your approach was experimental.
3. Financial Details
This section requires a breakdown of the costs associated with your R&D activities, including:
Staff salaries directly involved in R&D

You will need to calculate the amount of tax relief you are claiming based on your eligible costs. This involves:
Applying the correct rates for your scheme (e.g., SME or large company scheme)
Including any adjustments or exclusions required by tax rules
If you are unsure about the calculations, consulting a tax professional can help ensure accuracy.
