Graham Aaronson KC is a founding partner of Joseph Hage Aaronson LLP and chairs the firm’s tax disputes team.
During his time as a member of Pump Court Tax Chambers he established a reputation as one of the leading tax advisers and advocates of his generation. He has advised or represented most of the major corporations conducting business in the UK, appearing in many landmark cases such as BMBF v Mawson. He initiated the EU law challenges to the UK corporation tax regime in the ground-breaking Hoechst case, and since then he has been the lead counsel in most of the EU law based group litigation actions dealing with corporation tax.
Since founding JHA, he has focused on helping clients resolve their tax disputes with HMRC or other tax authorities. Where necessary this will include careful preparation and conduct of litigation, but wherever possible his preference is to seek to persuade the tax authorities to accept the client’s position, or to agree a negotiated settlement that achieves the best possible outcome for the client.
He specialises in commercial/corporate taxation, with particular sub-specialities in transfer pricing, oil and gas taxation, structured finance, State Aid and EU Law. He also has particular experience and expertise in dealing with football-related tax disputes, representing several very high profile players and agents.
