Mr. Allison’s clients include multinational corporations, financial institutions, sovereign wealth funds, global high-net-worth individuals, and professional athletes and entertainers. He has substantial industry experience in financial services, healthcare, utilities, and infrastructure.

Mr. Allison's practice involves complex federal, state, and cross-border tax controversy and litigation matters; related civil, criminal, and regulatory proceedings; and internal investigations.

Mr. Allison uses his tax controversy background to uniquely advise clients in a range of transactional and planning settings, including mergers, acquisitions and divestitures; private equity, hedge fund and real estate investments; bankruptcy and other restructurings; transfer pricing; and estate and gift tax issues. His work also involves pre- and post-transaction review and analysis of potential tax disputes for purposes of ASC 740, Schedule UTP, and other regulatory reporting and internal risk management, as well as the tax treatment and implications of non-tax litigation and investigations.

Mr. Allison serves as general counsel to a New York City-based SEC-registered fund manager and often counsels on SEC regulatory and enforcement matters and related compliance and oversight issues for investment advisers.
