Maria Kitt

Tax Director, Tax Insight LLP. Maria specialises in corporation tax and Research & Development (R&D) tax relief. She brings over two decades of experience in UK corporate taxation, including eleven years at HM Revenue & Customs, where she headed a corporation tax unit. Maria was practising as a corporate tax specialist for private clients at the time the UK’s R&D tax relief regimes were introduced in 2000 and 2004, giving her rare first-hand insight into both the original policy intent and the evolution of the legislation and guidance that followed. She is widely regarded as a technical authority on R&D tax relief, particularly in complex and high-value claims. She has been a regular contributor on corporation tax matters to Taxation magazine for more than twenty years and is frequently consulted on policy developments, compliance risk, and HMRC enquiry trends. Maria is the author of Research and Development Tax Relief, published by Bloomsbury Professional, which remains a key reference work for tax professionals. She continues to advise corporates, owner-managed businesses, and advisers on navigating the increasingly complex R&D tax landscape.
