An R&D Tax enquiry or compliance check is an HMRC investigation that examines whether your claim contains costs or projects that are not eligible for relief.

Even if your claim was 100% accurate and compliant, your enquiry is likely to be time-consuming, stressful, and take months to resolve.

But you can make the process much easier and faster by working with GrantTree.
