William J. Kambas

Bill provides tax planning advice relating to multi-national and multi-state residency, business, and investment activities, with a particular emphasis on tax structuring and choice of business entity for US and non-US business owners and investors.  This includes planning for inbound and outbound business transactions, cross-border investments, US tax treaty analysis, and the US income and estate tax consequences associated with the ownership of US real estate by non-US persons.  It also includes assisting clients with responding to inquiries from US federal and state tax authorities.  An integral part of Bill's practice involves working with families and/or their family offices to assist with the formation, management, and periodic evaluation of multi-national, multi-generational centralized control and management structures.

Bill is involved with Withers Bergman's Family Office special interest group and International Corporate Tax Group.  He is admitted to practice before the United States Tax Court.
