Tax Investigations and Disputes

Our practice not only comprises specialists in handling tax investigations and disputes for both corporates and individuals, but all of our lawyers have a background in transactional and advisory work that gives them technical expertise and commercial experience.

Our dedicated team of tax investigations and disputes lawyers includes former HMRC personnel, current Tribunal judges and CEDR accredited mediators. 

We have experience in taking cases to every level of the UK courts from the Tax Tribunal through to the Supreme Court, as well as to the European Court of Justice and in proceedings before foreign courts.

Our objective, however, is to deal with matters without recourse to litigation and for every success before the Courts, there are many cases that we have been able to resolve through discussions with HMRC, mediation or more formal alternative dispute resolution.

They're technically gifted, and they work incredibly hard."
