Tax Disputes

We have a well-established Tax Disputes practice and have regularly and successfully represented and advised clients in a wide range of disputes and investigations with and including tax authorities, including Her Majesty's Revenue and Customs (HMRC) in the UK. However, most tax disputes do not result in litigation and we have considerable expertise in assisting with enquiries from and the negotiation of settlements with tax authorities.

Specialists from our Dispute Resolution and Tax groups work closely together on tax disputes, forming a formidable, integrated team of experts able to deal with all aspects of the case innovatively, seamlessly and efficiently.

Significant public successes for our clients include the clarification of the tax treatment of dividends by the Court of Appeal in Nationwide v HMRC, the Court of Appeal's decision in FCE Bank on the application of the US/UK double tax treaty and the High Court's decision in Homeserve Membership Limited v HMRC (which had significant implications for many general insurers).

As a member of the Best Friends Tax Network we won 'European Tax Disputes Firm of the Year' at the European Tax Awards 2016.
