Matthew McKim is a seasoned international tax and trust lawyer, bringing twenty years of experience counseling clients on a wide range of U.S. and non-U.S. tax planning matters. Matt’s clients range from entrepreneurs wishing to establish a family office, to established global families managing their own wealth in the multibillions, to some of the world’s most renowned trust companies. Matt has extensive experience with a wide range of global family structures and common issues and prides himself on delivering efficient, strategic and results-oriented solutions for his clients.

He regularly assists clients (most often multinationals and their families) in navigating the United States legal system, generally from a tax perspective, but also with respect to the various other considerations which arise when families (or select family members) move to, or invest in, the United States. Matt has been referred to by his clients as their “global quarterback”, wherein he works with families to identify legal considerations (tax and non-tax alike) and provide solutions that are tax-efficient in nature but most importantly capture the client’s business needs and family succession considerations. Matt is versatile and resolute on delivering innovative, yet practical, legal strategies.

Matt has significant experience working with families in Latin America, Europe, Middle East and Africa, PRC, Hong Kong, Southeast Asia and, of course, the United States. He considers himself fortunate to work with some of the most successful businessmen, businesswomen, former politicians, professional athletes and celebrities in these regions and the trust companies and private banks that act for them.
