Cleary Gottlieb Steen & Hamilton has hired Diana Wollman, the former director of international strategy for the Internal Revenue Service ’s Large Business & International Division (LB&I), as a tax partner in the New York office.

She will advise clients on a broad range of federal and state tax issues, particularly tax controversy.


Wollman was responsible for developing and managing the international strategic programme for LB&I, the IRS division that audits multinational companies and individuals with international income, which she joined in September 2013. She focused on improving how the IRS audits international businesses and manages and uses its institutional knowledge and data. She also represented the IRS in OECD working groups, including some of the working groups on BEPS (Base Erosion and Profit Shifting), the Forum on Harmful Tax Practices, and the Forum on Tax Administration. She was one of a string of senior international tax figures to leave the IRS in 2014.


Before the IRS, Wollman was a partner of Sullivan & Cromwell in New York, where her practice covered federal and New York State tax controversies, complex cross-border transactions, fund and private equity work, and bankruptcy.
