Corporate tax veteran Shane Wallace has rejoined Deloitte Ireland as a partner in the tax practice.
The qualified solicitor joins from law firm William Fry, which he joined in 2014 from a previous stint with Deloitte of more than 10 years.
In his new role, Mr Wallace will support indigenous Irish companies and foreign-owned multinationals across industries including life sciences, technology, consumer products and property.
Mr Wallace is a chartered tax adviser as well as a qualified solicitor, and has "used these combined skills to work on a range of significant M&A and real estate transactions, both on the buy and sell side", Deloitte said.
He is also an elected council member of the Irish Tax Institute.
"I know first-hand the emphasis the team at Deloitte place on quality and delivering impact for our clients in a changing market and regulatory environment, and I am delighted to be joining the fold once again. I look forward to working with our clients as they navigate their way through ... significant changes, and support them in achieving their ambitions for their businesses," Mr Wallace said.
Head of tax at Deloitte Ireland, Lorraine Griffin, said: "Shane's breadth of experience and knowledge is an important addition to our team. We deliver the most value for our clients when we bring the breadth of our expertise to the challenges and the opportunities that they face.
"Shane's tax and legal background across a range of industries, and indeed disciplines, will strengthen our tax advisory and M&A offerings in this regard. We are delighted to welcome him back."
Tax professionals are in demand among Ireland's top advisory firms as a result of the economic recovery at home, record foreign direct investment, and demand from industry for advice on changes in global corporate tax structures and standards.
