R&D eligibility checker
Seven questions at most, and fewer if your answers settle it early — about a minute. It applies the tests that decide most claims and tells you plainly where you land, including when the answer is no. Nothing is stored, and there is no sign-up.

Who is claiming
Do you qualify for R&D tax relief?
This checker needs JavaScript, which does not appear to be running. The same ground is covered in writing on what counts as qualifying R&D, and we are happy to answer it directly — tell us what you are working on and we will tell you where you stand.
What this is, and what it is not
This checker walks the same ground a scoping call covers, in the same order. It is a first read on the answers you give, not a review of your claim and not tax advice: it cannot see your contracts, your cost records or the technical detail that decides a real position. Every route through it ends in the same place — a conversation with a chartered adviser, or a link to the guide that explains the point properly.
It will tell you when a claim looks unlikely. That is deliberate. If you would rather talk it through than click through, that costs nothing either.
Provided for illustration only. The tests applied here are the statutory ones as we describe them across this site, but a real eligibility position turns on detail this tool cannot see, including the scheme that applies to your accounting period, the treatment of your costs, contract terms and the state of the field at the time the work began. Its output is not tax advice and must not be relied on for any decision or filing. We build these tools carefully, but they are provided as they are, without warranty that they are accurate, complete or current: the rules change, and the tool may itself be wrong. To the fullest extent permitted by law we accept no liability for any error in it, or for any loss arising from its use or from reliance on its output. Our full website terms apply. Before acting, have the position confirmed by a competent chartered tax adviser.
Tests last reviewed 24 August 2026.

A first conversation costs nothing and commits you to nothing. You will speak to a qualified adviser, not a salesperson.
