Tax Disputes

In the increasingly complex and international area of tax legislation and practice, our team of global tax disputes experts can successfully support your business.

Our experience in all aspects of corporate, commercial, VAT and finance tax is designed to avoid disputes arising, however, we are often called upon to advise when, or even after, various schemes or transactions have completed and issues with the revenue authorities have arisen.

One area which distinguishes us from our competitors is the handling of cross-border transactions. The proliferation of tax disputes, which often involve one or more jurisdictions, is where we can bring clarity of focus. It is the strength of our tax teams in international offices and their relationships with local revenue authorities which has allowed clarity and transparency to solve disputes to the benefit of all parties. This same strength also allows us to build structures to take advantage of benign tax treatment in certain countries to produce innovative solutions for clients.
