Tax litigation and investigations

Our advice on all aspects of tax is designed to avoid disputes, but we are ideally placed to provide support when, or even after, various issues with revenue authorities arise.

A&O Shearman advises a broad range of clients on tax compliance and tax-related disputes and investigations, with particular experience of advising financial institutions. We handle litigation before national and international courts and specialist tax tribunals, including Corporation Tax and VAT disputes, and we liaise with tax authorities and advise on all issues associated with enforcement proceedings.

What sets us apart is our deep experience in handling cross-border transactions, with tax teams in our international offices enjoying strong relationships with local revenue authorities to support the smooth resolution of disputes for the benefit of all parties.
