Mercer & Hole, which industry sources say is one of the UK’s “top 50” accountancy firms, was founded in 1905, and has offices in London, Milton Keynes and St Albans.
Penman began his career in the field of tax more than 25 years ago, initially with the Inland Revenue.
In leaving BDO in the wake of its merger with PKF, Penman follows out the door fellow former PKF tax specialist John Cassidy, who, in April, joined Crowe Clark Whitehill’s tax investigations unit as a partner, after more than 12 years with PKF. Anne-Marie Boden, also with PKF at the time of the merger, is now a senior manager with KPMG.
At Mercer & Hole, where his title is senior private client tax manager, Penman said international tax issues, such as residence and domicile matters, will account for around 65% of his work. He is based at Mercer & Hole’s Fleet Place offices in London.
