Ellis has held a variety of positions in Deloitte, including in regional offices in Southampton and Reading as well as London. Most recently he led Deloitte UK’s global employer services business (GES) and served as talent leader for tax.
He succeeds Andy Hodge, who has led the practice for the past five years and is retiring from the firm.
David Sproul, senior partner and chief executive of Deloitte, said, “I am delighted to announce Matt as our new managing partner for tax. Matt has been a great leader of our global employer services practice and I am sure that he will bring the same leadership and focus to his new role as head of our tax practice.
“I also want to thank Andy Hodge for the great leadership he provided as managing partner for tax over the past five years.”
Ellis added, “I am thrilled to be taking on this role and feel extremely privileged and humbled to lead such a tremendous business at this crucial time. The tax environment has changed rapidly over the past few years. Technology and data analytics are playing an ever greater part in taxation, as compliance is now digital and HMRC continues to develop new systems.
"The UK is also at the forefront of legislating the agreed actions from the G20/ OECD Base Erosion and Profit Shifting project and there are major changes for employers and individuals too.
“I look forward to working with our talented teams across the country as we help clients understand, navigate and comply with these complex changes and build and grow our practice.”
The Big Four firm also announced that Andrew Bulley has been appointed as partner in the EMEA Centre for Regulatory Strategy.
Bulley joins from the Bank of England where he is director of life insurance supervision for the Prudential Regulatory Authority (PRA).
He played a key leadership role in the PRA’s roll-out of Solvency II to the life insurance industry.
Bulley is also a voting member of the board of supervisors of the European Insurance and Occupational Pensions Authority (EIOPA).
He also previously held senior roles at the Financial Services Authority (FSA).
Julian Leake, head of Deloitte’s financial services risk advisory practice, said, “Andrew’s extensive experience in insurance supervision, most recently in the life market, and his role on the Board of EIOPA make him a very significant addition to our risk and regulatory advisory practice.
"He will broaden the scope of our Centre’s work in insurance, further enhance our technical expertise and bring an extensive network of contacts, both in the UK and internationally.”
Bulley added, “Now is a time of far-reaching change for the global insurance industry. This is a tremendous opportunity for me to build on the Centre’s success to date and to work with colleagues in the UK, EMEA and internationally to make it a leading force in the area of insurance regulation.”
