Hugh Gunson


Hugh specialises in disputes and investigations across all areas of tax, both direct and indirect, for clients including individuals, trustees, family businesses and corporates.



Hugh specialises in tax disputes and investigations. His clients include internationally mobile high net worth clients and other private individuals, family businesses, trustees, entrepreneurs and corporates, both small and large. His practice covers the full range of UK taxes, both direct and indirect; including income tax, CGT, inheritance tax, SDLT, corporation tax and VAT. Hugh’s work frequently has a significant cross-border element, often combined with allegations of tax fraud or criminal behaviour.  

Hugh has experience of litigating tax cases at all levels, from the specialist tax tribunals through to the Court of Appeal and the Supreme Court.

A significant element of Hugh’s practice involves remedying unsuccessful planning (often involving complex trust arrangements), including by way of claims for mistake and rectification in both the UK and offshore jurisdictions. He also acts on tax-related professional negligence disputes and other trust and commercial disputes with a tax angle.

Hugh is a regular conference speaker and frequently writes in a number of tax and trust related publications, such as Tax Journal and Trusts and Trustees. He is a contributor to the most recent edition of Clarke's Offshore Tax Planning and the upcoming edition of Trust Taxation and Estate Planning.

Hugh is a Solicitor-Advocate (Higher Courts Civil Proceedings). Prior to joining Charles Russell Speechlys, he spent over six years in the tax department of a magic circle law firm and a year as a barrister at Pump Court Tax Chambers.
