What if my R&D project runs over multiple years?

You won’t be alone in this. In fact, many R&D projects have multi-year extensions, meaning that as long as you have expenditure that falls within the parameters of the guidance, then these projects can be used in more than one Research and development tax credit claim.

This means you can take the same approach each year that is shown within your supporting documents (as long as the costs and descriptions change), and then can proceed to submit your application. However, if you simply re-submit the same documentation, then you are more than likely to have an enquiry opened and will need to answer a range of questions about how you collated and prepared your submission.
