About Constantine Costas
Constantine Costas is a Partner in our innovation and capital tax reliefs team with extensive experience helping businesses claim tax incentives for innovation, including research & development (R&D) tax credits and patent box tax relief. He works with clients across all industries and at all stages of growth, from start-ups to FTSE100 companies. He has a special interest in technology and media, and financial services.
Constantine is a qualified Chartered Accountant (ACA) and began his career in corporate international tax at a top 10 accountancy practice. He has specialised in innovation reliefs for more than a decade, having spent time in a boutique R&D practice before joining RSM, with a brief to develop our client base in the London region.
"I live by the advice of US business executive Meg Whitman, who said: “Do what you love and success will follow. Passion is the fuel behind a successful career.” I’ve always had an interest in science and new technology, and my job allows me to focus on this. I’m passionate about innovation reliefs and the benefits they create, both for the companies I support and for the economy."
Outside of work, Constantine loves to travel and tries to ensure he experiences at least one new country (and perhaps just as importantly, one new cuisine) every year.
He is a self-confessed sports nerd who watches everything from football and rugby to the NFL.
