Tax Disputes & Enquiries

As the leading contentious tax practice in Ireland, A&L Goodbody consistently acts on the most significant tax disputes and enquiries, frequently having an international dimension.

Our team comprises experienced lawyers from our Tax and Litigation practices in collaboration with specialists from our other practice areas. We represent clients at all stages of domestic and international tax dispute and enquiry processes, including on tax authority queries and audits, liaison with Competent Authorities and proceedings before the Irish Tax Appeals Commission (TAC) and the Courts.
