THE FIRM JHA’s contentious tax team is led by the renowned Graham Aaronson QC, who has developed a trusted relationship with HMRC (appointed by them to chair the GAAR interim advisory panel), and with the UK Government (appointed by the Treasury to lead the GAAR study, and subsequently by the Prime Minister, David Cameron, in relation to the “Panama Papers“ allegations about his family).

The team includes Michael Anderson, Paul Farmer, Iain MacWhannell, Daniel Margolin QC, Simon Whitehead, Nahuel Acevedo-Peña, Francisco Alvarez, Steve Bousher, Megan Durnford, Joe Irwin, Jill Kaur, Ray McCann, Helen McGhee, Shofiq Miah and Tom O’Reilly. They are supported by in-house barristers, solicitors, and accountants, combining the best qualities of the bar and a law firm to deliver a cohesive approach to advising and representing clients throughout all stages of a dispute. In some of the most complex and sensitive private client cases we bring in the expertise of Emma Chamberlain, the renowned private client counsel with whom the firm has a close and long-standing relationship.

The team has particular expertise in highly sensitive matters across direct and indirect taxes (especially VAT and excise), including in relation to COP8 and COP9 HMRC enquiries (and in some cases criminal investigations), where it works proactively with HMRC to achieve the best possible outcome for clients, while paying the closest attention to preserving their privacy and maintaining confidentiality. The firm also has deep expertise in representing clients in disputes with overseas tax authorities.

Revelations such as the “Panama Papers” and “Pandora Papers” serve as important reminders that taxpayers need to consider their tax affairs and compliance obligations carefully and where relevant seek specialist advice from those that have a relationship of mutual respect and professionalism with HMRC. This is exactly what JHA offers. 

The firm's team members have acted in many of the most sensitive and highest value disputes of recent years, including those involving novel issues in transfer pricing, diverted profits tax, penalties and the compatibility of domestic tax rules with EU state aid rules.

Where it is essential to do so the team will carry a dispute through to litigation to achieve the result which they and the client consider to be the correct application of the tax law to the particular facts. But the firm’s preference wherever possible is to seek to persuade HMRC (or the relevant overseas tax authority) that the client’s filing position is correct, or to reach a settlement on the best possible terms.

Where litigation is required, JHA’s lawyers have experience across all of the domestic courts and tribunal system, from the First Tier Tribunal to the Supreme Court. The firm also represents clients in cases which are continuing before the General Court of the European Union and the Court of Justice of the European Union, and in overseas courts in high-value, complex tax disputes.

As is well known, JHA have also been the lead and test-case solicitors in almost all corporation tax Group Litigation Orders (GLOs), which bring together high court claims made by more than 50 multinational corporations. These are ground-breaking claims that challenge various discriminatory elements of UK tax legislation.
