Phil West, Steptoe’s chair, advises major global clients on international tax issues, and is widely regarded as one of the premier international tax lawyers in the United States.  Drawing on decades of experience and prior service as the Treasury Department’s international tax counsel, the senior international tax lawyer and policy official in the US government, he guides companies and high-net-worth individuals on issues of income deferral, foreign tax credits, transfer pricing, tax treaties, tax withholding and reporting (including FATCA), and the tax aspects of cross-border mergers, acquisitions, joint ventures, investment funds, and financings.  He helps clients favorably resolve controversies with, and obtain rulings from, the IRS, including on audit, at the administrative appeal level, with the Office of Chief Counsel, and, for issues arising under US tax treaties, with the United States competent authority.  He also has extensive practical experience advocating before the Treasury Department, Congress, and international organizations on both technical matters and on issues of broad policy significance.

In his role at Treasury, Mr. West played a central role in virtually every policy, legislative, and regulatory development in the international tax area.  He led tax treaty negotiations, discussions, and ratification efforts involving countries throughout the world, and played a major role in the US work at the OECD.  He has practical experience with many foreign tax systems and good relationships with foreign tax officials and private practitioners around the world.  He is regularly called on to advise government officials with respect to sensitive and complex tax matters, and has testified before Congress several times on international tax matters.  Chambers, The Legal 500 and other rankings consistently place him in the top tier of international tax practitioners.
