Large public companies, banks and government bodies turn to Arthur Cox‘s tax group for assistance with a broad range of matters. The team has a particularly strong corporate advisory practice, with expertise in IP structuring and financial services, including tax issues connected to securitisations, CLOs, CDOs and CMBSs; the group’s experience representing clients before the Tax Appeals Commission and the Irish superior courts is also noted. With expertise in structured finance, David Kilty heads the group, and is supported by chair of the firm Fintan Clancy, who is recognised for his experience advising on the tax issues arising from transactions. Chair of the firm Ailish Finnerty is another key member of the group, who focuses on international clients (particularly US clients) doing business in and through Ireland.
