Call 1997 Silk 2002

Malcolm Gammie started his tax career in the City with Linklaters & Paines. After a period of tax policy work at the Confederation of British Industry, he was among the first lawyers to work in the tax field with a leading accounting firm. At KMG Thomson McLintock (now part of KPMG), he was the first Director of the firm's National Tax Office before becoming its Director of National Tax Services.

In 1985 he returned to Linklaters & Paines and from 1987 to 1997 was one of its senior tax partners. He moved to the Bar in 1997 to concentrate on tax litigation and advisory work and took silk in 2002. Over his career, Malcolm has gained experience in most aspects of taxation and is noted as a leading practitioner in the commercial, European and international taxation fields.  In the 2018 UK Chambers Bar Awards Malcolm won Tax Silk of the Year. 

He is instructed by many of the leading tax practices in the City, and advises incorporated and unincorporated entities on all aspects of commercial, European and international taxation. 


Malcolm Gammie is among the leading advocates at the Revenue Bar. He has represented both Her Majesty’s Revenue and Customs and taxpayers is a series of high profile disputes, including for HMRC the long-running Eclipse 35 and Ingenious film scheme litigation. His experience as a solicitor in preparing cases, including handling both documentary and witness evidence, provides him with a unique insight into the conduct of litigation. At Linklaters, he had charge of cases before the Tax Tribunals as well as before both the High Court and the Court of Appeal. As an advocate he has represented taxpayers and the Revenue at all stages of tax appeals including the House of Lords, the Supreme Court and the European Court of Justice. He is noted for his painstaking attention to detail on all aspects of the litigation process. He has also assisted in negotiations with the Revenue leading to the satisfactory settlement of disputes.

In addition to his substantial litigation practice Malcolm also advises on all aspects of commercial, European and international taxation, for both incorporated and unincorporated entities, their shareholders and employees. He covers all the main direct taxes, value added tax, national insurance, stamp and other duties, and the related double tax treaty, European and administrative law. Malcolm's clients include many leading UK and foreign multi-national companies, banks, insurance companies and other financial institutions.
