International Tax


Domestic and foreign clients regularly retain Steptoe for tax-efficient structuring of their cross-border transactions and operations, as well as international tax advocacy before Congress, the Treasury Department, the IRS, the courts, as well as foreign tax authorities.  Our successes in these areas are achieved by leading lawyers with decades of practical experience and a strong commitment to solving our clients’ problems with practical judgment, technical skill, professionalism, and integrity.

Steptoe lawyers assist clients in the planning and the implementation of transactions, alert to the possibility that an audit or controversy may ensue.  Our substantial tax litigation experience enables us to anticipate how issues may be presented in the controversies and to plan accordingly.  Decisions made at the pre-controversy stage about substantive strategies, procedural tactics, and privilege questions may have a dramatic impact in later adversary proceedings.
