Advisers make break from Big 4 to set up new Swiss firm

MME – Legal Tax Compliance is the name of the new Swiss firm which four former Big 4 practitioners have started.

Thomas Linder and Andreas Müller, both ex-KPMG, Samuel Bussmann, formerly of PwC, and Christoph Rechsteiner, previously at Deloitte, will be partners in the new firm, which will advise companies and their executives, and private clients on business law and tax issues. MME – Legal Tax Compliance will have offices in Zurich and Zug.

The tax practice will advise mid-sized companies, multinational groups, business owners and family offices on acquisitions; corporate restructurings and migrations; and international tax planning, particularly relating to venture capital, intellectual property and financing; real estate and cross-border transactions.
