Apply for advance assurance on a Research and Development (R&D) tax relief claim
Ask HMRC if your first R&D Corporation Tax relief claim will be accepted, if you're a small and medium-sized enterprise.
There may be other steps you must complete before applying for advance assurance. Check the steps you need to take to correctly claim R&D tax relief.
What advance assurance is
Advance assurance is a voluntary scheme that allows you to send HMRC details of your company’s R&D work, before claiming R&D tax relief on your Company Tax Return.
We’ll check the details in your application and if we agree the relief applies to you, we’ll guarantee the claim will be accepted, as long as it’s in line with what was discussed and agreed in your application. This is known as an ‘advance assurance agreement’.
The advance assurance agreement will be for your first 3 accounting periods only.
An advance assurance agreement does not mean that you’ve claimed the R&D tax relief. You must still claim it using your Company Tax Return.

After you’ve applied
HMRC will contact you by email to arrange a telephone call with your company so that we can talk about your R&D in more detail. This is normally a short telephone call, but it may involve a longer discussion or a visit to your company if the case is more complex.
We will then send you a letter telling you if your application for advance assurance was successful or not.
If you’re given advance assurance
We will send you a letter explaining your company’s responsibilities and what happens if your R&D activities change.
We may contact you after you’ve submitted your first claim on your Company Tax Return, to check it matches the details in your advance assurance application.
If you’re not given advance assurance
We will send you a letter detailing the reasons why. You will not be able to appeal this decision or re-submit an application for advance assurance. If you still think you’re due R&D tax relief you can submit a claim in your Company Tax Return.

You must tell HMRC you want to claim R&D tax relief before you claim it on your Company Tax Return by completing a claim notification form. If you’ve applied for advance assurance, you still need to do this form.
