It is widely recognised for its financial services tax practice, which has included recent advice on major corporate restructurings, investments and acquisitions. The firm is also acclaimed for its indirect tax expertise and abilities in tax controversy. Joe Duffy, Turlough Galvin, Shane Hogan, Catherine O’Meara and Gerry Thornton are at the top of the market, with Tomás Bailey and indirect tax specialist Matthew Broadstock also impressing.
