Does my business qualify?

R&D Tax Credits are a UK Government incentive designed to encourage innovation by rewarding companies that invest in advancing science and technology.

01.

Subject to UK Corporation Tax

You must be a UK registered company that is liable for Corporation Tax.

02.

Advance in science or technology

Your project aims to advance science or technology by going beyond routine improvements.

03.

Technical uncertainty
